Unfortunately, existing files already have the bug and may not properly be processed. The fix uses constants from the GuardTime API lib to prevent such problems in the future.

However, it bugs under valgrind and similar memory debuggers. - fix build on FreeBSD Thanks to Christiano Rolim for the patch --------------------------------------------------------------------------- Version 7.4.2 [v7.4-stable] 2013-07-04 - bugfix: in RFC5425 TLS, multiple wildcards in auth could cause segfault - bugfix: RainerScript object required parameters were not properly checked - this clould result to segfaults on startup if parameters were missing. - bugfix: double-free in omelasticsearch closes: http://bugzilla.adiscon.com/show_bug.cgi?id=461 a security advisory for this bug is available at: http://www.lsexperts.de/advisories/lse-2013-07-03.txt CVE: CVE-2013-4758 PLEASE NOTE: This issue only existed if omelasticsearch was used in a non-default configuration, where the "errorfile" parameter was specified. Without that parameter set, the bug could not be triggered. Thanks to Markus Vervier and Marius Ionescu for providing a detailled bug report.

We now have our own ratelimiter. This can mitigate against journal database corruption, when the journal re-sends old data. This is a current bug in systemd journal, but we won't outrule this to happen in the future again. So it is better to have a safeguard in place. By default, we permit 20,000 messages witin 10 minutes. This may be a bit restrictive, but given the risk potential it seems reasonable. Users requiring larger traffic flows can always adjust the value. - bugfix: potential loop in rate limiting if the message that tells about rate-limiting gets rate-limited itself, it will potentially create and endless loop - bugfix: potential segfault in imjournal if journal DB is corrupted - bugfix: prevent a segfault in imjournal if state file is not defined - bugfix imzmq3: potential segfault on startup if no problem happend at startup, everything went fine Thanks to Hongfei Cheng and Brian Knox for the patch --------------------------------------------------------------------------- Version 7.4.0 [v7.4-stable] 2013-06-06 This starts a new stable branch based on 7.3.15 plus the following changes: - add --enable-cached-man-pages ./configure option permits to build rsyslog on a system where rst2man is not installed. In that case, cached versions of the man pages are used (they were built during "make dist", so they should be current for the version in question. - doc bugfix: ReadMode wrong in imfile doc, two values were swapped Thanks to jokajak@gmail.com for mentioning this closes: http://bugzilla.adiscon.com/show_bug.cgi?id=450 - imjournal: no longer do periodic wakeup - bugfix: potential hang *in debug mode* on rsyslogd termination This ONLY affected rsyslogd if it were running with debug output enabled. - bugfix: $template statement with multiple spaces lead to invalid tpl name If multiple spaces were used in front of the template name, all but one of them became actually part of the template name. So $template a,"..." would be name " a", and as such "a" was not available, e.g. in *.* /var/log/file;a This is a legacy config problem. As it was unreported for many years, no backport of the fix to old versions will happen. This is a long-standing bug that was only recently reported by forum user mc-sim.

Thanks to Marius Tomaschewski for reporting the bug. - bugfix: segfault due to invalid dynafile cache handling Accidently, the old-style cache size parameter was used when the dynafile cache was created in a RainerScript action. If the old-style size was lower than the one actually set, this lead to misadressing when the size was overrun, and that could lead to all kinds of "interesting things", often in segfaults. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=440 --------------------------------------------------------------------------- Version 7.3.13 [beta] 2013-04-29 - added omrabbitmq module (contributed, untested) Note: this is unsupported and as such was moved immediately into the beta version. Thanks to Vaclav Tomec for providing this module. - bugfix: build problem when --enable-encryption was not selected Thanks to Michael Biebl for fixing this. - doc bugfix: omfile parameter "VeryRobustZip" was documentas as "VeryReliableZip" closes: http://bugzilla.adiscon.com/show_bug.cgi?id=437 Thanks to Thomas Doll for reporting this. --------------------------------------------------------------------------- Version 7.3.12 [devel] 2013-04-25 - added doc for omelasticsearch Thanks to Radu Gheorghe for the doc contribution. - omelasticsearch: _id field support for bulk operations closes: http://bugzilla.adiscon.com/show_bug.cgi?id=392 Thanks to Jérôme Renard for the idea and patches. - max number of templates for plugin use has been increased to five - platform compatibility enhancement: solve compile issue with libgcrypt do not use GCRY_CIPHER_MODE_AESWRAP where not available - fix compile on Solaris Thanks to Martin Carpenter for the patch. - bugfix: off-by-one error in handling local FQDN name (regression) A remporary buffer was allocated one byte too small. Did only affect startup, not actual operations. Came up during routine tests, and can have no effect once the engine runs. Bug was introduced in 7.3.11. - bugfix: build problems on Solaris closes: http://bugzilla.adiscon.com/show_bug.cgi?id=436 - bugfix: block size limit was not properly honored - bugfix: potential segfault in guardtime signature provider it could segfault if an error was reported by the GuardTime API, because an invalid free could happen then --------------------------------------------------------------------------- Version 7.3.11 [devel] 2013-04-23 - added support for encrypting log files - omhiredis: added support for redis pipeline support Thanks to Brian Knox for the patch. - bugfix: $PreserveFQDN is not properly working Thanks to Louis Bouchard for the patch closes: http://bugzilla.adiscon.com/show_bug.cgi?id=426 - bugfix: imuxsock aborted due to problem in ratelimiting code Thanks to Tomas Heinrich for the patch. - bugfix: imuxsock aborted under some conditions regression from ratelimiting enhancements - this was a different one to the one Tomas Heinrich patched. - bugfix: timestamp problems in imkmsg --------------------------------------------------------------------------- Version 7.3.10 [devel] 2013-04-10 - added RainerScript re_extract() function - omrelp: added support for RainerScript-based configuration - omrelp: added ability to specify session timeout - templates now permit substring extraction relative to end-of-string - bugfix: failover/action suspend did not work correctly This was experienced if the retry action took more than one second to complete. For suspending, a cached timestamp was used, and if the retry took longer, that timestamp was already in the past. As a result, the action never was kept in suspended state, and as such no failover happened. The suspend functionalit now does no longer use the cached timestamp (should not have any performance implication, as action suspend occurs very infrequently). - bugfix: gnutls RFC5425 driver had some undersized buffers Thanks to Tomas Heinrich for the patch. - bugfix: nested if/prifilt conditions did not work properly closes: http://bugzilla.adiscon.com/show_bug.cgi?id=415 - bugfix: imuxsock aborted under some conditions regression from ratelimiting enhancements - bugfix: build problems on Solaris Thanks to Martin Carpenter for the patches. --------------------------------------------------------------------------- Version 7.3.9 [devel] 2013-03-27 - support for signing logs added - imudp: now supports user-selectable inputname - omlibdbi: now supports transaction interface if recent enough lbdbi is present - imuxsock: add ability to NOT create/delete sockets during startup and shutdown closes: http://bugzilla.adiscon.com/show_bug.cgi?id=259 - imfile: errors persisting state file are now reported closes: http://bugzilla.adiscon.com/show_bug.cgi?id=292 - imfile: now detects file change when rsyslog was inactive Previosly, this case could not be detected, so if a file was overwritten or rotated away while rsyslog was stopped, some data was missing. This is now detected and the new file being forwarded right from the beginning. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=228 - updated systemd files to match current systemd source - bugfix: imudp scheduling parameters did affect main thread, not imudp closes: http://bugzilla.adiscon.com/show_bug.cgi?id=409 - bugfix: build problem on platforms without GLOB_NOMAGIC - bugfix: build problems on non-Linux platforms - bugfix: stdout/stderr were not closed on forking but were closed when running in the forground - this was just reversed of what it should be. This is a regression of a recent change. --------------------------------------------------------------------------- Version 7.3.8 [devel] 2013-03-18 - imrelp: now supports listening to IPv4/v6 only instead of always both build now requires librelp 1.0.2 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=378 - bugfix: mmanon did not build on some platforms (e.g. Ubuntu) - bugfix: segfault in expression optimizer closes: http://bugzilla.adiscon.com/show_bug.cgi?id=423 - bugfix: imuxsock was missing SysSock.ParseTrusted module parameter To use that functionality, legacy rsyslog.conf syntax had to be used. Also, the doc was missing information on the "ParseTrusted" set of config directives. - bugfix: include files got included in the wrong order closes: http://bugzilla.adiscon.com/show_bug.cgi?id=411 This happens if an $IncludeConfig directive was done on multiple files (e.g. the distro default of $IncludeConfig /etc/rsyslog.d/*.conf). In that case, the order of include file processing is reversed, which could lead to all sorts of problems. Thanks to Nathan Stratton Treadway for his great analysis of the problem, which made bug fixing really easy. --------------------------------------------------------------------------- Version 7.3.7 [devel] 2013-03-12 - add support for anonymizing IPv4 addresses - add support for writing to the Linux Journal (omjournal) - imuxsock: add capability to ignore messages from ourselfes This helps prevent message routing loops, and is vital to have if omjournal is used together with traditional syslog. - field() function now supports a string as field delimiter - added ability to configure debug system via rsyslog.conf - bugfix: imuxsock segfault when system log socket was used - bugfix: mmjsonparse segfault if new-style config was used - bugfix: script == comparison did not work properly on JSON objects - bugfix: field() function did never return "***FIELD NOT FOUND***" instead it returned "***ERROR in field() FUNCTION***" in that case --------------------------------------------------------------------------- Version 7.3.6 [devel] 2013-01-28 - greatly improved speed of large-array [N]EQ RainerScript comparisons Thanks to David Lang for a related discussion that inspired the idea to do this with a much simpler (yet sufficient) approach than orignally planned for. - greatly improved speed of DNS cache for large cache sizes - general performance improvements - omfile: added stats counters for dynafile caches - omfile: improved async writing, finally enabled full async write also fixed a couple of smaller issues along that way - impstats: added ability to write stats records to local file and avoid going through the syslog log stream. syslog logging can now also be turned off (see doc for details). - bugfix: imklog issued wrong facility in error messages ...what could lead to problems in other parts of the code - fix compile problem in imklog - added capability to output thread-id-to-function debug info This is a useful debug aid, but nothing of concern for regular users. --------------------------------------------------------------------------- Version 7.3.5 [devel] 2012-12-19 - ommysql: addded batching/transaction support - enhanced script optimizer to optimize common PRI-based comparisons These constructs are especially used in SUSE default config files, but also by many users (as they are more readable than the equivalent PRI-based filter). - omudpspoof: add support for new config system - omudpspoof: add support for packets larger than 1472 bytes On Ethernet, they need to be transmitted in multiple fragments. While it is known that fragmentation can cause issues, it is the best choice to be made in that case. Also improved debug output. - bugfix: omudpspoof failed depending on the execution environment The v7 engine closes fds, and closed some of libnet's fds as well, what lead to problems (unfortunately, at least some libnet versions do not report a proper error state but still "success"...). The order of libnet calls has been adjusted to by in sync with what the core engine does. - bugfix: segfault on imuxsock startup if system log socket is used and no ratelimiting supported. Happens only during initial config read phase, once this is over, everything works stable. - bugfix: mmnormalize build problems - bugfix: mmnormalize could abort rsyslog if config parameter was in error - bugfix: no error message for invalid string template parameters rather a malformed template was generated, and error information emitted at runtime. However, this could be quite confusing. Note that with this "bugfix" user experience changes: formerly, rsyslog and the affected actions properly started up, but the actions did not produce proper data. Now, there are startup error messages and the actions are NOT executed (due to missing template due to template error). - bugfix[minor]: invalid error code when mmnormalize could not access rulebase - bugfix(kind of): script optimizer did not work for complex boolean expressions - doc bugfix: corrections and improvements in mmnormalize html doc page - bugfix: some message properties could be garbled due to race condition This happened only on very high volume systems, if the same message was being processed by two different actions. This was a regression caused by the new config processor, which did no longer properly enable msg locking in multithreaded cases. The bugfix is actually a refactoring of the msg locking code - we no longer do unlocked operations, as the use case for it has mostly gone away. It is potentially possible only at very low-end systems, and there the small additional overhead of doing the locking does not really hurt. Instead, the removal of that capability can actually slightly improve performance in common cases, as the code path is smaller and requires slightly less memory writes. That probably outperforms the extra locking overhead (which in the low-end case always happens in user space, without need for kernel support as we can always directly aquire the lock - there is no contention at all). - build system cleanup (thanks to Michael Biebl for this!) - bugfix: omelasticsearch did not properly compile on some platforms due to missing libmath. Thanks to Michael Biebl for the fix --------------------------------------------------------------------------- Version 7.3.4 [devel] 2012-11-23 - further (and rather drastically) improved disk queue performance we now save one third of the IO calls - imklog: added ParseKernelTimestamp parameter (import from 5.10.2) Thanks to Marius Tomaschewski for the patch. - imklog: added KeepKernelTimestamp parameter (import from 5.10.2) Thanks to Marius Tomaschewski for the patch. - bugfix: improper handling of backslash in string-type template()s - bugfix: leading quote (") in string-type template() lead to thight loop on startup - bugfix: no error msg on invalid field option in legacy/string template - bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds ... actually, they are microseconds. So the fractional part of the timestamp was not properly formatted. (import from 5.10.2) Thanks to Marius Tomaschewski for the bug report and the patch idea. --------------------------------------------------------------------------- Version 7.3.3 [devel] 2012-11-07 - improved disk queue performance - bugfix: dynafile zip files could be corrupted This could happen if a dynafile was destructed before the first write. In practice, this could happen if few lines were written to a file and it then became evicted from the dynafile cache. This would probably look very random, because it depended on the timing in regard to message volume and dynafile cache size. --------------------------------------------------------------------------- Version 7.3.2 [devel] 2012-10-30 - mmnormalize: support for v6+ config interface added - mmjsonparse: support for v6+ config interface added --------------------------------------------------------------------------- Version 7.3.2 [devel] 2012-10-30 - totally reworked ratelimiting and "last message repeated n times" all over rsyslog code. Each of the supported inputs now supports linux-like ratelimiting (formerly only imuxsock did). Also, the "last message repeated n times" is now processed at the input side and no longer at the output side of rsyslog processing. This provides the basis for new future additions as well as usually more performance and a much simpler output part (which can be even further refactored). - imtcp: support for Linux-Type ratelimiting added - imptcp: support for Linux-Type ratelimiting added - imudp enhancements: * support for input batching added (performance improvement) * support for Linux-Type ratelimiting added - permited action-like statements (stop, call, ...) in action lists - bugfix: segfault on startup when modules using MSG_PASSING mode are used - omelasticsearch: support for writing data errors to local file added - omelasticsearch: fix check for bulk processing status response --------------------------------------------------------------------------- Version 7.3.1 [devel] 2012-10-19 - optimized template processing performance, especially for $NOW family of properties - change lumberjack cookie to "@cee:" from "@cee: " CEE originally specified the cookie with SP, whereas other lumberjack tools used it without space. In order to keep interop with lumberjack, we now use the cookie without space as well. I hope this can be changed in CEE as well when it is released at a later time. Thanks to Miloslav Trmač for pointing this out and a similiar v7 patch. - bugfix: imuxsock and imklog truncated head of received message This happened only under some circumstances. Thanks to Marius Tomaschewski, Florian Piekert and Milan Bartos for their help in solving this issue. - bugfix: imuxsock did not properly honor $LocalHostIPIF --------------------------------------------------------------------------- Version 7.3.0 [devel] 2012-10-09 - omlibdbi improvements, added * support for config load phases & module() parameters * support for default templates * driverdirectory is now cleanly a global parameter, but can no longer be specified as an action paramter. Note that in previous versions this parameter was ignored in all but the first action definition - improved omfile zip writer to increase compression This was achieved by somewhat reducing the robustness of the zip archive. This is controlled by the new action parameter "VeryReliableZip". ---------------------------------------------------------------------------- Version 7.2.8 [v7-stable] 2013-0?-?? - bugfix: potential segfault on startup when builtin module was specified in module() statement. Thanks to Marius Tomaschewski for reporting the bug. - bugfix: segfault due to invalid dynafile cache handling Accidently, the old-style cache size parameter was used when the dynafile cache was created in a RainerScript action. If the old-style size was lower than the one actually set, this lead to misadressing when the size was overrun, and that could lead to all kinds of "interesting things", often in segfaults. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=440 ---------------------------------------------------------------------------- Version 7.2.7 [v7-stable] 2013-04-17 - rsyslogd startup information is now properly conveyed back to init when privileges are beging dropped Actually, we have moved termination of the parent in front of the priv drop. So it shall work now in all cases. See code comments in commit for more details. - If forking, the parent now waits for a maximum of 60 seconds for termination by the child - improved debugging support in forked (auto-backgrounding) mode The rsyslog debug log file is now continued to be written across the fork. - updated systemd files to match current systemd source - bugfix: failover/action suspend did not work correctly This was experienced if the retry action took more than one second to complete. For suspending, a cached timestamp was used, and if the retry took longer, that timestamp was already in the past. As a result, the action never was kept in suspended state, and as such no failover happened. The suspend functionalit now does no longer use the cached timestamp (should not have any performance implication, as action suspend occurs very infrequently). - bugfix: nested if/prifilt conditions did not work properly closes: http://bugzilla.adiscon.com/show_bug.cgi?id=415 - bugfix: script == comparison did not work properly on JSON objects [backport from 7.3 branch] - bugfix: imudp scheduling parameters did affect main thread, not imudp closes: http://bugzilla.adiscon.com/show_bug.cgi?id=409 - bugfix: imuxsock rate-limiting could not be configured via legacy conf Rate-limiting for the system socket could not be configured via legacy configuration directives. However, the new-style RainerScript config options worked. Thanks to Milan Bartos for the patch. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=390 - bugfix: using group resolution could lead to endless loop Thanks to Tomas Heinrich for the patch. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=310 - bugfix: $mmnormalizeuseramsg paramter was specified with wrong type Thank to Renzhong Zhang for alerting us of the problem. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=420 - bugfix: RainerScript getenv() function caused segfault when var was not found. Thanks to Philippe Muller for the patch. - bugfix: several issues in imkmsg see bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=421#c8 - bugfix: imuxsock was missing SysSock.ParseTrusted module parameter To use that functionality, legacy rsyslog.conf syntax had to be used. Also, the doc was missing information on the "ParseTrusted" set of config directives. - bugfix: parameter action.execOnlyWhenPreviousIsSuspended was accidently of integer-type. For obvious reasons, it needs to be boolean. Note that this change can break existing configurations if they circumvented the problem by using 0/1 values. - doc bugfix: rsyslog.conf man page had invalid file format info closes: http://bugzilla.adiscon.com/show_bug.cgi?id=418 ---------------------------------------------------------------------------- Version 7.2.6 [v7-stable] 2013-03-05 - slightly improved config parser error messages when invalid escapes happen - bugfix: include files got included in the wrong order closes: http://bugzilla.adiscon.com/show_bug.cgi?id=411 This happens if an $IncludeConfig directive was done on multiple files (e.g. the distro default of $IncludeConfig /etc/rsyslog.d/*.conf). In that case, the order of include file processing is reversed, which could lead to all sorts of problems. Thanks to Nathan Stratton Treadway for his great analysis of the problem, which made bug fixing really easy. - bugfix: omelasticsearch failed when authentication data was provided ... at least in most cases it emitted an error message: "snprintf failed when trying to build auth string" Thanks to Joerg Heinemann for alerting us. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=404 - bugfix: some property-based filter were incorrectly parsed This usually lead to a syntax error on startup and rsyslogd not actually starting up. The problem was the regex, which did not care for double quote characters to follow in the action part - unfortunately something that can frequently happen with v6+ format. An example: :programname, isequal, "as" {action(type="omfile" ...) } Here, the part :programname, isequal, "as" {action(type="omfile" was treated as the property filter, and the rest as action part. Obviously, this did not work out. Unfortunately, such situations usually resulted in very hard to understand error messages. ---------------------------------------------------------------------------- Version 7.2.5 [v7-stable] 2013-01-08 - build system cleanup (thanks to Michael Biebl for this!) - bugfix: omelasticsearch did not properly compile on some platforms due to missing libmath. Thanks to Michael Biebl for the fix - bugfix: invalid DST handling under Solaris Thanks to Scott Severtson for the patch. - bugfix: on termination, actions were incorrectly called The problem was that incomplete fiter evaluation was done *during the shutdown phase*. This affected only the LAST batches being processed. No problem existed during the regular run. Could usually only happen on very busy systems, which were still busy during shutdown. - bugfix: very large memory consumption (and probably out of memory) when FromPos was specified in template, but ToPos not. Thanks to Radu Gheorghe for alerting us of this bug. - bugfix: timeval2syslogTime cause problems on some platforms due to invalid assumption on structure data types. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=394 Thanks to David Hill for the patch [under ASL2.0 as per email conversation 2013-01-03]. - bugfix: compile errors in im3195 Thanks to Martin Körper for the patch - bugfix: doGetFileCreateMode() had invalid validity check ;) Thanks to Chandler Latour for the patch. - bugfix: mmjsonparse errornously returned action error when no CEE cookie was present. ---------------------------------------------------------------------------- Version 7.2.4 [v7-stable] 2012-12-07 - enhance: permit RFC3339 timestamp in local log socket messages Thanks to Sebastien Ponce for the patch. - imklog: added ParseKernelTimestamp parameter (import from 5.10.2) Thanks to Marius Tomaschewski for the patch. - fix missing functionality: ruleset(){} could not specify ruleset queue The "queue.xxx" parameter set was not supported, and legacy ruleset config statements did not work (by intention). The fix introduces the "queue.xxx" parameter set. It has some regression potential, but only for the new functionality. Note that using that interface it is possible to specify duplicate queue file names, which will cause trouble. This will be solved in v7.3, because there is a too-large regression potential for the v7.2 stable branch. - imklog: added KeepKernelTimestamp parameter (import from 5.10.2) Thanks to Marius Tomaschewski for the patch. - bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds ... actually, they are microseconds. So the fractional part of the timestamp was not properly formatted. (import from 5.10.2) Thanks to Marius Tomaschewski for the bug report and the patch idea. - bugfix: supportoctetcountedframing parameter did not work in imptcp - bugfix: modules not (yet) supporting new conf format were not properly registered. This lead to a "module not found" error message instead of the to-be-expected "module does not support new style" error message. That invalid error message could be quite misleading and actually stop people from addressing the real problem (aka "go nuts" ;)) - bugfix: template "type" parameter is mandatory (but was not) - bugfix: some message properties could be garbled due to race condition This happened only on very high volume systems, if the same message was being processed by two different actions. This was a regression caused by the new config processor, which did no longer properly enable msg locking in multithreaded cases. The bugfix is actually a refactoring of the msg locking code - we no longer do unlocked operations, as the use case for it has mostly gone away. It is potentially possible only at very low-end systems, and there the small additional overhead of doing the locking does not really hurt. Instead, the removal of that capability can actually slightly improve performance in common cases, as the code path is smaller and requires slightly less memory writes. That probably outperforms the extra locking overhead (which in the low-end case always happens in user space, without need for kernel support as we can always directly aquire the lock - there is no contention at all). ---------------------------------------------------------------------------- Version 7.2.3 [v7-stable] 2012-10-21 - regression fix: rsyslogd terminated when wild-card $IncludeConfig did not find actual include files. For example, if this directive is present: $IncludeConfig /etc/rsyslog.d/*.conf and there are no *.conf files in /etc/rsyslog.d (but rsyslog.d exists), rsyslogd will emit an error message and terminate. Previous (and expected) behaviour is that an empty file set is no problem. HOWEVER, if the directory itself does not exist, this is flagged as an error and will load to termination (no startup). Unfortunately, this is often the case by default in many distros, so this actually prevents rsyslog startup. ---------------------------------------------------------------------------- Version 7.2.2 [v7-stable] 2012-10-16 - doc improvements - enabled to build without libuuid, at loss of uuid functionality this enables smoother builds on older systems that do not support libuuid. Loss of functionality should usually not matter too much as uuid support has only recently been added and is very seldom used. - bugfix: omfwd did not properly support "template" parameter - bugfix: potential segfault when re_match() function was used Thanks to oxpa for the patch. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=371 - bugfix: potential abort of imtcp on rsyslogd shutdown - bugfix: imzmq3 segfault with PULL subscription Thanks to Martin Nilsson for the patch. - bugfix: improper handling of backslash in string-type template()s - bugfix: leading quote (") in string-type template() lead to thight loop on startup - bugfix: no error msg on invalid field option in legacy/string template - bugfix: potential segfault due to invalid param handling in comparisons This could happen in RainerScript comparisons (like contains); in some cases an unitialized variable was accessed, which could lead to an invalid free and in turn to a segfault. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=372 Thanks to Georgi Georgiev for reporting this bug and his great help in solving it. - bugfix: no error msg on unreadable $IncludeConfig path - bugfix: $IncludeConfig did not correctly process directories closes: http://bugzilla.adiscon.com/show_bug.cgi?id=376 The testbench was also enhanced to check for these cases. Thanks to Georgi Georgiev for the bug report. - bugfix: make rsyslog compile on kfreebsd again closes: http://bugzilla.adiscon.com/show_bug.cgi?id=380 Thanks to Guillem Jover for the patch. - bugfix: garbled message if field name was used with jsonf property option The length for the field name was invalidly computed, resulting in either truncated field names or including extra random data. If the random data contained NULs, the rest of the message became unreadable. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=374 - bugfix: potential segfault at startup with property-based filter If the property name was followed by a space before the comma, rsyslogd aborted on startup. Note that no segfault could happen if the initial startup went well (this was a problem with the config parser). closes: http://bugzilla.adiscon.com/show_bug.cgi?id=381 - bugfix: imfile discarded some file parts File lines that were incomplete (LF missing) *at the time imfile polled the file* were partially discarded. That part of the line that was read without the LF was discarded, and the rest of the line was submitted in the next polling cycle. This is now changed so that the partial content is saved until the complete line is read. Note that the patch affects only read mode 0. Thanks to Milan Bartos for providing the base idea for the solution. ---------------------------------------------------------------------------- Version 7.2.1 [v7-stable] 2012-10-29 - bugfix: ruleset()-object did only support a single statement - added -D rsyslogd option to enable config parser debug mode - improved syntax error messages by outputting the error token - the rsyslog core now suspeneds actions after 10 failures in a row This was former the case after 1,000 failures and could cause rsyslog to be spammed/ressources misused. See the v6 compatibility doc for more details. - ommongodb rate-limits error messages to prevent spamming the syslog closes (for v7.2): http://bugzilla.adiscon.com/show_bug.cgi?id=366 ---------------------------------------------------------------------------- Version 7.2.0 [v7-stable] 2012-10-22 This starts a new stable branch based on 7.1.12 plus the following changes: - bugfix: imuxsock did not properly honor $LocalHostIPIF - omruleset/omdiscard do no longer issue "deprecated" warings, as 7.1 grammar does not permit to use the replacements under all circumstances ---------------------------------------------------------------------------- Version 7.1.12 [beta] 2012-10-18 - minor updates to better support newer systemd developments Thanks to Michael Biebl for the patches. - build system cleanup Thanks to Michael Biebl for the patch series. - cleanup: removed remains of -c option (compatibility mode) both from code & doc and emitted warning message if still used closes: http://bugzilla.adiscon.com/show_bug.cgi?id=361 Thanks to Michael Biebl for reporting & suggestions - bugfix: imklog truncated head of received message This happened only under some circumstances. Thanks to Marius Tomaschewski and Florian Piekert for their help in solving this issue. ---------------------------------------------------------------------------- Version 7.1.11 [beta] 2012-10-16 - bugfix: imuxsock truncated head of received message This happened only under some circumstances. Thanks to Marius Tomaschewski, Florian Piekert and Milan Bartos for their help in solving this issue. - bugfix: do not crash if set statement is used with date field Thanks to Miloslav Trmač for the patch. - change lumberjack cookie to "@cee:" from "@cee: " CEE originally specified the cookie with SP, whereas other lumberjack tools used it without space. In order to keep interop with lumberjack, we now use the cookie without space as well. I hope this can be changed in CEE as well when it is released at a later time. Thanks to Miloslav Trmač for pointing this out and a similiar v7 patch. - added deprecated note to omruleset (plus clue to use "call") - added deprecated note to discard action (plus clue to use "stop") --------------------------------------------------------------------------- Version 7.1.10 [beta] 2012-10-11 - bugfix: m4 directory was not present in release tarball - bugfix: small memory leak with string-type templates - bugfix: small memory leak when template was specified in omfile - bugfix: some config processing warning messages were treated as errors - bugfix: small memory leak when processing action() statements - bugfix: unknown action() parameters were not reported --------------------------------------------------------------------------- Version 7.1.9 [beta] 2012-10-09 - bugfix: comments inside objects (e.g. action()) were not properly handled - bugfix: in (non)equal comparisons the position of arrays influenced result This behaviour is OK for "contains"-type of comparisons (which have quite different semantics), but not for == and <>, which shall be commutative. This has been fixed now, so there is no difference any longer if the constant string array is the left or right hand operand. We solved this via the optimizer, as it keeps the actual script execution code small. --------------------------------------------------------------------------- Version 7.1.8 [beta] 2012-10-02 - bugfix: ruleset(){} directive errornously changed default ruleset much like the $ruleset legacy conf statement. This potentially lead to statements being assigned to the wrong ruleset. - improved module doc - added "parser" parameter to ruleset(), so that parser chain can be configured - implemented "continue" RainerScript statement --------------------------------------------------------------------------- Version 7.1.7 [devel] 2012-10-01 - implemented RainerScript "call" statement - implemented RainerScript array-based string comparison operations - implemented imtcp "permittedPeers" module-global parameter - imudp: support for specifying multiple ports via array added --------------------------------------------------------------------------- Version 7.1.6 [devel] 2012-09-28 - implemented RainerScript input() statement, including support for it in major input plugins - implemented RainerScript ruleset() statement --------------------------------------------------------------------------- Version 7.1.5 [devel] 2012-09-25 - implemented RainerScript prifield() function - implemented RainerScript field() function - added new module imkmsg to process structured kernel log Thanks to Milan Bartos for contributing this module - implemented basic RainerScript optimizer, which will speed up script operations - bugfix: invalid free if function re_match() was incorrectly used if the config file parser detected that param 2 was not constant, some data fields were not initialized. The destructor did not care about that. This bug happened only if rsyslog startup was unclean. --------------------------------------------------------------------------- Version 7.1.4 [devel] 2012-09-19 - implemented ability for CEE-based properties to be stored in disk queues - implemented string concatenation in expressions via &-operator - implemented json subtree copy in variable assignment - implemented full JSON support for variable manipulation - introduced "subtree"-type templates - bugfix: omfile action did not respect "template" parameter ... and used default template in all cases - bugfix: MsgDup() did not copy CEE structure This function was called at various places, most importantly during "last messages repeated n times" processing and omruleset. If CEE(JSON) data was present, it was lost as part of the copy process. - bugfix: debug output indicated improper queue type --------------------------------------------------------------------------- Version 7.1.3 [devel] 2012-09-17 - introduced "set" and "unset" config statements - bugfix: missing support for escape sequences in RainerScript only \' was supported. Now the usual set is supported. Note that v5 used \x as escape where x was any character (e.g. "\n" meant "n" and NOT LF). This also means there is some incompatibility to v5 for well-know sequences. Better break it now than later. - bugfix: invalid property name in property-filter could cause abort if action chaining (& operator) was used http://bugzilla.adiscon.com/show_bug.cgi?id=355 Thanks to pilou@gmx.com for the bug report --------------------------------------------------------------------------- Version 7.1.2 [devel] 2012-09-12 - bugfix: messages were duplicated, sometimes massively regression from new code in 7.1.1 and reason for early release - bugfix: remove invalid socket option call from imuxsock Thanks to Cristian Ionescu-Idbohrn and Jonny Törnbom - bugfix: abort when invalid property name was configured in property-based filter - bugfix: multiple rulesets did no longer work correctly (7.1.1 regression) --------------------------------------------------------------------------- Version 7.1.1 [devel] 2012-09-11 - MAJOR NEW FEATURE: rulengine now fully supports nesting including if ... then ... else ... constructs. This is a big change and it obviously has a lot of bug potential. - BSD-style (filter) blocks are no longer supported see http://www.rsyslog.com/g/BSD for details and solution - imuxsock now stores trusted properties by default in the CEE root This was done in order to keep compatible with other implementations of the lumberjack schema Thanks to Miloslav Trmač for pointing to this. - bugfix: string-generating templates caused abort if CEE field could not be found --------------------------------------------------------------------------- Version 7.1.0 [devel] 2012-09-06 - added support for hierarchical properties (CEE/lumberjack) - added pure JSON output plugin parameter passing mode - ommongodb now supports templates - bugfix: imtcp could abort on exit due to invalid free() - imported bugfixes from 6.4.1 --------------------------------------------------------------------------- Version 6.6.1 [v6-stable] 2012-10-?? - bugfix: build problems on some platforms - bugfix: misaddressing of $mmnormalizeuserawmsg parameter On many platforms, this has no effect at all. At some, it may cause a segfault. The problem occurs only during config phase, no segfault happens when rsyslog has fully started. - fix API "glitch" in some plugins This did not affect users, but could have caused trouble in the future for developers. - bugfix: no error msg on invalid field option in legacy/string template - bugfix: no error msg on unreadable $IncludeConfig path - bugfix: $IncludeConfig did not correctly process directories closes: http://bugzilla.adiscon.com/show_bug.cgi?id=376 The testbench was also enhanced to check for these cases. Thanks to Georgi Georgiev for the bug report. - bugfix: spurios error messages from imuxsock about (non-error) EAGAIN Thanks to Marius Tomaschewski for the patch. - imklog: added $klogParseKernelTimestamp option When enabled, kernel message [timestamp] is converted for message time. Default is to use receive time as in 5.8.x and before, because the clock used to create the timestamp is not supposed to be as accurate as the monotonic clock (depends on hardware and kernel) resulting in differences between kernel and system messages which occurred at same time. Thanks to Marius Tomaschewski for the patch. - imklog: added $klogKeepKernelTimestamp option When enabled, the kernel [timestamp] remains at begin of each message, even it is used for the message time too. Thanks to Marius Tomaschewski for the patch. - bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds ... actually, they are microseconds. So the fractional part of the timestamp was not properly formatted. Thanks to Marius Tomaschewski for the bug report and the patch idea. - bugfix: hostname set in rsyslog.conf was not picked up until HUP which could also mean "never" or "not for a very long time". Thanks to oxpa for providing analysis and a patch - bugfix: some message properties could be garbled due to race condition This happened only on very high volume systems, if the same message was being processed by two different actions. This was a regression caused by the new config processor, which did no longer properly enable msg locking in multithreaded cases. The bugfix is actually a refactoring of the msg locking code - we no longer do unlocked operations, as the use case for it has mostly gone away. It is potentially possible only at very low-end systems, and there the small additional overhead of doing the locking does not really hurt. Instead, the removal of that capability can actually slightly improve performance in common cases, as the code path is smaller and requires slightly less memory writes. That probably outperforms the extra locking overhead (which in the low-end case always happens in user space, without need for kernel support as we can always directly aquire the lock - there is no contention at all). - bugfix: invalid DST handling under Solaris Thanks to Scott Severtson for the patch. --------------------------------------------------------------------------- Version 6.6.0 [v6-stable] 2012-10-22 This starts a new stable branch, based on the 6.5.x series, plus: - bugfix: imuxsock did not properly honor $LocalHostIPIF --------------------------------------------------------------------------- Version 6.5.1 [beta] 2012-10-11 - added tool "logctl" to handle lumberjack logs in MongoDB - imfile ported to new v6 config interface - imfile now supports config parameter for maximum number of submits which is a fine-tuning parameter in regard to input baching - added pure JSON output plugin parameter passing mode - ommongodb now supports templates - bugfix: imtcp could abort on exit due to invalid free() - bugfix: remove invalid socket option call from imuxsock Thanks to Cristian Ionescu-Idbohrn and Jonny Törnbom - added pure JSON output plugin parameter passing mode - ommongodb now supports templates - bugfix: imtcp could abort on exit due to invalid free() - bugfix: missing support for escape sequences in RainerScript only \' was supported. Now the usual set is supported. Note that v5 used \x as escape where x was any character (e.g. "\n" meant "n" and NOT LF). This also means there is some incompatibility to v5 for well-know sequences. Better break it now than later. - bugfix: small memory leaks in template() statements these were one-time memory leaks during startup, so they did NOT grow during runtime - bugfix: config validation run did not always return correct return state - bugfix: config errors did not always cause statement to fail This could lead to startup with invalid parameters. --------------------------------------------------------------------------- Version 6.5.0 [devel] 2012-08-28 - imrelp now supports non-cancel thread termination (but now requires at least librelp 1.0.1) - implemented freeCnf() module interface This was actually not present in older versions, even though some modules already used it. The implementation was now done, and not in 6.3/6.4 because the resulting memory leak was ultra-slim and the new interface handling has some potential to seriously break things. Not the kind of thing you want to add in late beta state, if avoidable. - added --enable-debugless configure option for very high demanding envs This actually at compile time disables a lot of debug code, resulting in some speedup (but serious loss of debugging capabilities) - added new 0mq plugins (via czmq lib) Thanks to David Kelly for contributing these modules - bugfix: omhdfs did no longer compile - bugfix: SystemLogSocketAnnotate did not work correctly Thanks to Miloslav Trmač for the patch - $SystemLogParseTrusted config file option Thanks to Milan Bartos for the patch - added template config directive - added new uuid message property Thanks to Jérôme Renard for the idea and patches. Note: patches were released under ASL 2.0, see http://bugzilla.adiscon.com/show_bug.cgi?id=353 --------------------------------------------------------------------------- Version 6.4.3 [V6-STABLE/NEVER RELEASED] 2012-??-?? This version was never released as 6.6.0 came quickly enough. Note that all these patches here are present in 6.6.0. - cleanup: removed remains of -c option (compatibility mode) both from code & doc and emitted warning message if still used closes: http://bugzilla.adiscon.com/show_bug.cgi?id=361 Thanks to Michael Biebl for reporting & suggestions - bugfix: imuxsock and imklog truncated head of received message This happened only under some circumstances. Thanks to Marius Tomaschewski, Florian Piekert and Milan Bartos for their help in solving this issue. - change lumberjack cookie to "@cee:" from "@cee: " CEE originally specified the cookie with SP, whereas other lumberjack tools used it without space. In order to keep interop with lumberjack, we now use the cookie without space as well. I hope this can be changed in CEE as well when it is released at a later time. Thanks to Miloslav Trmač for pointing this out and a similiar v7 patch. - bugfix: comments inside objects (e.g. action()) were not properly handled - bugfix: sysklogd-emulating standard template was no longer present in v6 This was obviously lost during the transition to the new config format. Thanks to Milan Bartos for alerting us and a patch! - bugfix: some valid legacy PRI filters were flagged as errornous closes: http://bugzilla.adiscon.com/show_bug.cgi?id=358 This happend to filters of the style "local0,local1.*", where the multiple facilities were comma-separated. - bugfix: imuxsock did not properly honor $LocalHostIPIF --------------------------------------------------------------------------- Version 6.4.2 [V6-STABLE] 2012-09-20 - bugfix: potential abort, if action queue could not be properly started This most importantly could happen due to configuration errors. - bugfix: remove invalid socket option call from imuxsock Thanks to Cristian Ionescu-Idbohrn and Jonny Törnbom - bugfix: missing support for escape sequences in RainerScript only \' was supported. Now the usual set is supported. Note that v5 used \x as escape where x was any character (e.g. "\n" meant "n" and NOT LF). This also means there is some incompatibility to v5 for well-know sequences. Better break it now than later. - bugfix: config validation run did not always return correct return state --------------------------------------------------------------------------- Version 6.4.1 [V6-STABLE] 2012-09-06 - bugfix: multiple main queues with same queue file name were not detected This lead to queue file corruption. While the root cause is a config error, it is a bug that this important and hard to find config error was not detected by rsyslog. - bugfix: "jsonf" property replacer option did generate invalid JSON in JSON, we have "fieldname":"value", but the option emitted "fieldname"="value". Interestingly, this was accepted by a couple of sinks, most importantly elasticsearch. Now the correct format is emitted, which causes a remote chance that some things that relied on the wrong format will break. Thanks to Miloslav Trmač for the patch - change $!all-json did emit an empty (thus non-JSON) string if no libee data was present. It now emits {} and thus valid JSON. There is a small risk that this may break some things that relied on the previous inconsistency. Thanks to Miloslav Trmač for the patch - bugfix: omusrsmsg incorrect return state & config warning handling During config file processing, Omusrmsg often incorrectly returned a warning status, even when no warning was present (caused by uninitialized variable). Also, the core handled warning messages incorrectly, and treated them as errors. As a result, omusrmsg (most often) could not properly be loaded. Note that this only occurs with legacy config action syntax. This was a regression caused by an incorrect merge in to the 6.3.x codebase. Thanks to Stefano Mason for alerting us of this bug. - bugfix: Fixed TCP CheckConnection handling in omfwd.c. Interface needed to be changed in lower stream classes. Syslog TCP Sending is now resumed properly. Unfixed, that lead to non-detection of downstate of remote hosts. --------------------------------------------------------------------------- Version 6.4.0 [V6-STABLE] 2012-08-20 - THIS IS THE FIRST VERSION OF THE 6.4.x STABLE BRANCH It includes all enhancements made in 6.3.x plus what is written in the ChangeLog below. - omelasticsearch: support for parameters parent & dynparent added - bugfix: imtcp aborted when more than 2 connections were used. Incremented pthread stack size to 4MB for imtcp, imptcp and imttcp closes: http://bugzilla.adiscon.com/show_bug.cgi?id=342 - bugfix: imptcp aborted when $InputPTCPServerBindRuleset was used - bugfix: problem with cutting first 16 characters from message with bAnnotate Thanks to Milan Bartos for the patch. --------------------------------------------------------------------------- Version 6.3.12 [BETA] 2012-07-02 - support for elasticsearch via omelasticsearch added Note that this module has been tested quite well by a number of folks, and this is why we merge in new functionality in a late beta stage. Even if problems would exist, only users of omelasticsearch would experience them, making it a pretty safe addition. - bugfix: $ActionName was not properly honored Thanks to Abby Edwards for alerting us --------------------------------------------------------------------------- Version 6.3.11 [BETA] 2012-06-18 - bugfix: expression-based filters with AND/OR could segfault due to a problem with boolean shortcut operations. From the user's perspective, the segfault is almost non-deterministic (it occurs when a shortcut is used). Thanks to Lars Peterson for providing the initial bug report and his support in solving it. - bugfix: "last message repeated n times" message was missing hostname Thanks to Zdenek Salvet for finding this bug and to Bodik for reporting --------------------------------------------------------------------------- Version 6.3.10 [BETA] 2012-06-04 - bugfix: delayble source could block action queue, even if there was a disk queue associated with it. The root cause of this problem was that it makes no sense to delay messages once they arrive in the action queue - the "input" that is being held in that case is the main queue worker, what makes no sense. Thanks to Marcin for alerting us on this problem and providing instructions to reproduce it. - bugfix: invalid free in imptcp could lead to abort during startup - bugfix: if debug message could end up in log file when forking if rsyslog was set to auto-background (thus fork, the default) and debug mode to stdout was enabled, debug messages ended up in the first log file opened. Currently, stdout logging is completely disabled in forking mode (but writing to the debug log file is still possible). This is a change in behaviour, which is under review. If it causes problems to you, please let us know. Thanks to Tomas Heinrich for the patch. - bugfix: --enable-smcustbindcdr configure directive did not work closes: http://bugzilla.adiscon.com/show_bug.cgi?id=330 Thanks to Ultrabug for the patch. - bugfix: made rsyslog compile when libestr ist not installed in /usr Thanks to Miloslav Trmač for providing patches and suggestions --------------------------------------------------------------------------- Version 6.3.9 [BETA] 2012-05-22 - bugfix: imtcp could cause hang during reception this also applied to other users of core file tcpsrv.c, but imtcp was by far the most prominent and widely-used, the rest rather exotic (like imdiag) - added capability to specify substrings for field extraction mode - added the "jsonf" property replacer option (and fieldname) - bugfix: omudpspoof did not work correctly if no spoof hostname was configured - bugfix: property replacer option "json" could lead to content loss message was truncated if escaping was necessary - bugfix: assigned ruleset was lost when using disk queues This looked quite hard to diagnose for disk-assisted queues, as the pure memory part worked well, but ruleset info was lost for messages stored inside the disk queue. - bugfix/imuxsock: solving abort if hostname was not set; configured hostname was not used (both merge regressions) -bugfix/omfile: template action parameter was not accepted (and template name set to "??" if the parameter was used) Thanks to Brian Knox for alerting us on this bug. - bugfix: ommysql did not properly init/exit the mysql runtime library this could lead to segfaults. Triggering condition: multiple action instances using ommysql. Thanks to Tomas Heinrich for reporting this problem and providing an initial patch (which my solution is based on, I need to add more code to clean the mess up). - bugfix: rsyslog did not terminate when delayable inputs were blocked due to unvailable sources. Fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=299 Thanks to Marcin M for bringing up this problem and Andre Lorbach for helping to reproduce and fix it. - added capability to specify substrings for field extraction mode - bugfix: disk queue was not persisted on shutdown, regression of fix to http://bugzilla.adiscon.com/show_bug.cgi?id=299 The new code also handles the case of shutdown of blocking light and full delayable sources somewhat smarter and permits, assuming sufficient timouts, to persist message up to the max queue capacity. Also some nits in debug instrumentation have been fixed. --------------------------------------------------------------------------- Version 6.3.8 [DEVEL] 2012-04-16 - added $PStatJSON directive to permit stats records in JSON format - added "date-unixtimestamp" property replacer option to format as a unix timestamp (seconds since epoch) - added "json" property replacer option to support JSON encoding on a per-property basis - added omhiredis (contributed module) - added mmjsonparse to support recognizing and parsing JSON enhanced syslog messages - upgraded more plugins to support the new v6 config format: - ommysql - omlibdbi - omsnmp - added configuration directives to customize queue light delay marks $MainMsgQueueLightDelayMark, $ActionQueueLightDelayMark; both specify number of messages starting at which a delay happens. - added message property parsesuccess to indicate if the last run higher-level parser could successfully parse the message or not (see property replacer html doc for details) - bugfix: abort during startup when rsyslog.conf v6+ format was used in a certain way - bugfix: property $!all-json made rsyslog abort if no normalized data was available - bugfix: memory leak in array passing output module mode - added configuration directives to customize queue light delay marks - permit size modifiers (k,m,g,...) in integer config parameters Thanks to Jo Rhett for the suggestion. - bugfix: hostname was not requeried on HUP Thanks to Per Jessen for reporting this bug and Marius Tomaschewski for his help in testing the fix. - bugfix: imklog invalidly computed facility and severity closes: http://bugzilla.adiscon.com/show_bug.cgi?id=313 - added configuration directive to disable octet-counted framing for imtcp, directive is $InputTCPServerSupportOctetCountedFraming for imptcp, directive is $InputPTCPServerSupportOctetCountedFraming - added capability to use a local interface IP address as fromhost-ip for locally originating messages. New directive $LocalHostIPIF --------------------------------------------------------------------------- Version 6.3.7 [DEVEL] 2012-02-02 - imported refactored v5.9.6 imklog linux driver, now combined with BSD driver - removed imtemplate/omtemplate template modules, as this was waste of time The actual input/output modules are better copy templates. Instead, the now-removed modules cost time for maintenance AND often caused confusion on what their role was. - added a couple of new stats objects - improved support for new v6 config system. The build-in output modules now all support the new config language - bugfix: facility local was not correctly interpreted in legacy filters Was only accepted if it was the first PRI in a multi-filter PRI. Thanks to forum user Mark for bringing this to our attention. - bugfix: potential abort after reading invalid X.509 certificate closes: http://bugzilla.adiscon.com/show_bug.cgi?id=290 Thanks to Tomas Heinrich for the patch - bufgix: legacy parsing of some filters did not work correctly - bugfix: rsyslog aborted during startup if there is an error in loading an action and legacy configuration mode is used - bugfix: bsd klog driver did no longer compile - relicensed larger parts of the code under Apache (ASL) 2.0 --------------------------------------------------------------------------- Version 6.3.6 [DEVEL] 2011-09-19 - added $InputRELPServerBindRuleset directive to specify rulesets for RELP - bugfix: config parser did not support properties with dashes in them inside property-based filters. Thanks to Gerrit Seré for reporting this. --------------------------------------------------------------------------- Version 6.3.5 [DEVEL] (rgerhards/al), 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: mark message processing did not work correctly - imudp&imtcp now report error if no listener at all was defined Thanks to Marcin for suggesting this error message. - bugfix: potential misadressing in property replacer --------------------------------------------------------------------------- Version 6.3.4 [DEVEL] (rgerhards), 2011-08-02 - added support for action() config object * in rsyslog core engine * in omfile * in omusrmsg - bugfix: omusrmsg format usr1,usr2 was no longer supported - bugfix: misaddressing in config handler In theory, can cause segfault, in practice this is extremely unlikely Thanks to Marcin for alertig me. --------------------------------------------------------------------------- Version 6.3.3 [DEVEL] (rgerhards), 2011-07-13 - rsyslog.conf format: now parsed by RainerScript parser this provides the necessary base for future enhancements as well as some minor immediate ones. For details see: http://blog.gerhards.net/2011/07/rsyslog-633-config-format-improvements.html - performance of script-based filters notably increased - removed compatibility mode as we expect people have adjusted their confs by now - added support for the ":omfile:" syntax for actions --------------------------------------------------------------------------- Version 6.3.2 [DEVEL] (rgerhards), 2011-07-06 - added support for the ":omusrmsg:" syntax in configuring user messages - systemd support: set stdout/stderr to null - thx to Lennart for the patch - added support for obtaining timestamp for kernel message from message If the kernel time-stamps messages, time is now take from that timestamp instead of the system time when the message was read. This provides much better accuracy. Thanks to Lennart Poettering for suggesting this feature and his help during implementation. - added support for obtaining timestamp from system for imuxsock This permits to read the time a message was submitted to the system log socket. Most importantly, this is provided in microsecond resolution. So we are able to obtain high precision timestampis even for messages that were - as is usual - not formatted with them. This also simplifies things in regard to local time calculation in chroot environments. Many thanks to Lennart Poettering for suggesting this feature, providing some guidance on implementing it and coordinating getting the necessary support into the Linux kernel. - bugfix: timestamp was incorrectly calculated for timezones with minute offset closes: http://bugzilla.adiscon.com/show_bug.cgi?id=271 - bugfix: memory leak in imtcp & subsystems under some circumstances This leak is tied to error conditions which lead to incorrect cleanup of some data structures. --------------------------------------------------------------------------- Version 6.3.1 [DEVEL] (rgerhards), 2011-06-07 - added a first implementation of a DNS name cache this still has a couple of weaknesses, like no expiration of entries, suboptimal algorithms -- but it should perform much better than what we had previously. Implementation will be improved based on feedback during the next couple of releases --------------------------------------------------------------------------- Version 6.3.0 [DEVEL] (rgerhards), 2011-06-01 - introduced new config system http://blog.gerhards.net/2011/06/new-rsyslog-config-system-materializes.html --------------------------------------------------------------------------- Version 6.2.2 [v6-stable], 2012-06-13 - build system improvements and spec file templates Thanks to Abby Edwards for providing these enhancements - bugfix: disk queue was not persisted on shutdown, regression of fix to http://bugzilla.adiscon.com/show_bug.cgi?id=299 The new code also handles the case of shutdown of blocking light and full delayable sources somewhat smarter and permits, assuming sufficient timouts, to persist message up to the max queue capacity. Also some nits in debug instrumentation have been fixed. - bugfix: --enable-smcustbindcdr configure directive did not work closes: http://bugzilla.adiscon.com/show_bug.cgi?id=330 Thanks to Ultrabug for the patch. - add small delay (50ms) after sending shutdown message There seem to be cases where the shutdown message is otherwise not processed, not even on an idle system. Thanks to Marcin for bringing this problem up. - support for resolving huge groups closes: http://bugzilla.adiscon.com/show_bug.cgi?id=310 Thanks to Alec Warner for the patch - bugfix: potential hang due to mutex deadlock closes: http://bugzilla.adiscon.com/show_bug.cgi?id=316 Thanks to Andreas Piesk for reporting&analyzing this bug as well as providing patches and other help in resolving it. - bugfix: property PROCID empty instead of proper nilvalue if not present If it is not present, it must have the nilvalue "-" as of RFC5424 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=332 Thanks to John N for reporting this issue. - bugfix: did not compile under solaris due to $uptime property code For the time being, $uptime is not supported on Solaris - bugfix: "last message repeated n times" message was missing hostname Thanks to Zdenek Salvet for finding this bug and to Bodik for reporting --------------------------------------------------------------------------- Version 6.2.1 [v6-stable], 2012-05-10 - change plugin config interface to be compatible with pre-v6.2 system The functionality was already removed (because it is superseeded by the v6.3+ config language), but code was still present. I have now removed those parts that affect interface. Full removal will happen in v6.3, in order to limit potential regressions. However, it was considered useful enough to do the interface change in v6-stable; this also eases merging branches! - re-licensed larger parts of the codebase under the Apache license 2.0 - bugfix: omprog made rsyslog abort on startup if not binary to execute was configured - bugfix: imklog invalidly computed facility and severity closes: http://bugzilla.adiscon.com/show_bug.cgi?id=313 - bugfix: stopped DA queue was never processed after a restart due to a regression from statistics module - bugfix: memory leak in array passing output module mode - bugfix: ommysql did not properly init/exit the mysql runtime library this could lead to segfaults. Triggering condition: multiple action instances using ommysql. Thanks to Tomas Heinrich for reporting this problem and providing an initial patch (which my solution is based on, I need to add more code to clean the mess up). - bugfix: rsyslog did not terminate when delayable inputs were blocked due to unvailable sources. Fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=299 Thanks to Marcin M for bringing up this problem and Andre Lorbach for helping to reproduce and fix it. - bugfix/tcpflood: sending small test files did not work correctly --------------------------------------------------------------------------- Version 6.2.0 [v6-stable], 2012-01-09 - bugfix (kind of): removed numerical part from pri-text see v6 compatibility document for reasons - bugfix: race condition when extracting program name, APPNAME, structured data and PROCID (RFC5424 fields) could lead to invalid characters e.g. in dynamic file names or during forwarding (general malfunction of these fields in templates, mostly under heavy load) - bugfix: imuxsock did no longer ignore message-provided timestamp, if so configured (the *default*). Lead to no longer sub-second timestamps. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=281 - bugfix: omfile returns fatal error code for things that go really wrong previously, RS_RET_RESUME was returned, which lead to a loop inside the rule engine as omfile could not really recover. - bugfix: rsyslogd -v always said 64 atomics were not present thanks to mono_matsuko for the patch - bugfix: potential abort after reading invalid X.509 certificate closes: http://bugzilla.adiscon.com/show_bug.cgi?id=290 Thanks to Tomas Heinrich for the patch - enhanced module loader to not rely on PATH_MAX - imuxsock: added capability to "annotate" messages with "trusted information", which contains some properties obtained from the system and as such sure to not be faked. This is inspired by the similiar idea introduced in systemd. --------------------------------------------------------------------------- Version 6.1.12 [BETA], 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: mark message processing did not work correctly - bugfix: potential misadressing in property replacer - bugfix: memcpy overflow can occur in allowed sender checkig if a name is resolved to IPv4-mapped-on-IPv6 address Found by Ismail Dönmez at suse - bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) - bugfix: fixed incorrect state handling for Discard Action (transactions) Note: This caused all messages in a batch to be set to COMMITTED, even if they were discarded. --------------------------------------------------------------------------- Version 6.1.11 [BETA] (rgerhards), 2011-07-11 - systemd support: set stdout/stderr to null - thx to Lennart for the patch - added support for the ":omusrmsg:" syntax in configuring user messages - added support for the ":omfile:" syntax in configuring user messages --------------------------------------------------------------------------- Version 6.1.10 [BETA] (rgerhards), 2011-06-22 - bugfix: problems in failover action handling closes: http://bugzilla.adiscon.com/show_bug.cgi?id=270 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=254 - bugfix: mutex was invalidly left unlocked during action processing At least one case where this can occur is during thread shutdown, which may be initiated by lower activity. In most cases, this is quite unlikely to happen. However, if it does, data structures may be corrupted which could lead to fatal failure and segfault. I detected this via a testbench test, not a user report. But I assume that some users may have had unreproducable aborts that were cause by this bug. --------------------------------------------------------------------------- Version 6.1.9 [BETA] (rgerhards), 2011-06-14 - bugfix: problems in failover action handling closes: http://bugzilla.adiscon.com/show_bug.cgi?id=270 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=254 - bugfix: mutex was invalidly left unlocked during action processing At least one case where this can occur is during thread shutdown, which may be initiated by lower activity. In most cases, this is quite unlikely to happen. However, if it does, data structures may be corrupted which could lead to fatal failure and segfault. I detected this via a testbench test, not a user report. But I assume that some users may have had unreproducable aborts that were cause by this bug. - bugfix/improvement:$WorkDirectory now gracefully handles trailing slashes - bugfix: memory leak in imtcp & subsystems under some circumstances This leak is tied to error conditions which lead to incorrect cleanup of some data structures. [backport from v6.3] - bugfix: $ActionFileDefaultTemplate did not work closes: http://bugzilla.adiscon.com/show_bug.cgi?id=262 --------------------------------------------------------------------------- Version 6.1.8 [BETA] (rgerhards), 2011-05-20 - official new beta version (note that in a sense 6.1.7 was already beta, so we may release the first stable v6 earlier than usual) - new module mmsnmptrapd, a sample message modification module - import of minor bug fixes from v4 & v5 --------------------------------------------------------------------------- Version 6.1.7 [DEVEL] (rgerhards), 2011-04-15 - added log classification capabilities (via mmnormalize & tags) - speeded up tcp forwarding by reducing number of API calls this especially speeds up TLS processing - somewhat improved documentation index - bugfix: enhanced imudp config processing code disabled due to wrong merge (affected UDP realtime capabilities) - bugfix (kind of): memory leak with tcp reception epoll handler This was an extremely unlikely leak and, if it happend, quite small. Still it is better to handle this border case. - bugfix: IPv6-address could not be specified in omrelp this was due to improper parsing of ":" closes: http://bugzilla.adiscon.com/show_bug.cgi?id=250 - bugfix: do not open files with full privileges, if privs will be dropped This make the privilege drop code more bulletproof, but breaks Ubuntu's work-around for log files created by external programs with the wrong user and/or group. Note that it was long said that this "functionality" would break once we go for serious privilege drop code, so hopefully nobody still depends on it (and, if so, they lost...). - bugfix: pipes not opened in full priv mode when privs are to be dropped --------------------------------------------------------------------------- Version 6.1.6 [DEVEL] (rgerhards), 2011-03-14 - enhanced omhdfs to support batching mode. This permits to increase performance, as we now call the HDFS API with much larger message sizes and far more infrequently - improved testbench among others, life tests for ommysql (against a test database) have been added, valgrind-based testing enhanced, ... - bugfix: minor memory leak in omlibdbi (< 1k per instance and run) - bugfix: (regression) omhdfs did no longer compile - bugfix: omlibdbi did not use password from rsyslog.con closes: http://bugzilla.adiscon.com/show_bug.cgi?id=203 - systemd support somewhat improved (can now take over existing log sockt) - bugfix: discard action did not work under some circumstances fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=217 - bugfix: file descriptor leak in gnutls netstream driver fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=222 - fixed compile problem in imtemplate fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=235 --------------------------------------------------------------------------- Version 6.1.5 [DEVEL] (rgerhards), 2011-03-04 - improved testbench - enhanced imtcp to use a pool of worker threads to process incoming messages. This enables higher processing rates, especially in the TLS case (where more CPU is needed for the crypto functions) - added support for TLS (in anon mode) to tcpflood - improved TLS error reporting - improved TLS startup (Diffie-Hellman bits do not need to be generated, as we do not support full anon key exchange -- we always need certs) - bugfix: fixed a memory leak and potential abort condition this could happen if multiple rulesets were used and some output batches contained messages belonging to more than one ruleset. fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=226 fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=218 - bugfix: memory leak when $RepeatedMsgReduction on was used bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=225 - bugfix: potential abort condition when $RepeatedMsgReduction set to on as well as potentially in a number of other places where MsgDup() was used. This only happened when the imudp input module was used and it depended on name resolution not yet had taken place. In other words, this was a strange problem that could lead to hard to diagnose instability. So if you experience instability, chances are good that this fix will help. --------------------------------------------------------------------------- Version 6.1.4 [DEVEL] (rgerhards), 2011-02-18 - bugfix/omhdfs: directive $OMHDFSFileName rendered unusable due to a search and replace-induced bug ;) - bugfix: minor race condition in action.c - considered cosmetic This is considered cosmetic as multiple threads tried to write exactly the same value into the same memory location without sync. The method has been changed so this can no longer happen. - added pmsnare parser module (written by David Lang) - enhanced imfile to support non-cancel input termination - improved systemd socket activation thanks to Marius Tomaschewski - improved error reporting for $WorkDirectory non-existance and other detectable problems are now reported, and the work directory is NOT set in this case - bugfix: pmsnare causded abort under some conditions - bugfix: abort if imfile reads file line of more than 64KiB Thanks to Peter Eisentraut for reporting and analysing this problem. bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=221 - bugfix: queue engine did not properly slow down inputs in FULL_DELAY mode when in disk-assisted mode. This especially affected imfile, which created unnecessarily queue files if a large set of input file data was to process. - bugfix: very long running actions could prevent shutdown under some circumstances. This has now been solved, at least for common situations. - bugfix: fixed compile problem due to empty structs this occured only on some platforms/compilers. thanks to Dražen Kačar for the fix --------------------------------------------------------------------------- Version 6.1.3 [DEVEL] (rgerhards), 2011-02-01 - experimental support for monogodb added - added $IMUDPSchedulingPolicy and $IMUDPSchedulingPriority config settings - added $LocalHostName config directive - improved tcpsrv performance by enabling multiple-entry epoll so far, we always pulled a single event from the epoll interface. Now 128, what should result in performance improvement (less API calls) on busy systems. Most importantly affects imtcp. - imptcp now supports non-cancel termination mode, a plus in stability - imptcp speedup: multiple worker threads can now be used to read data - new directive $InputIMPTcpHelperThreads added - bugfix: fixed build problems on some platforms namely those that have 32bit atomic operations but not 64 bit ones - bugfix: local hostname was pulled too-early, so that some config directives (namely FQDN settings) did not have any effect - enhanced tcpflood to support multiple sender threads this is required for some high-throughput scenarios (and necessary to run some performance tests, because otherwise the sender is too slow). - added some new custom parsers (snare, aix, some Cisco "specialities") thanks to David Lang --------------------------------------------------------------------------- Version 6.1.2 [DEVEL] (rgerhards), 2010-12-16 - added experimental support for log normalizaton (via liblognorm) support for normalizing log messages has been added in the form of mmnormalize. The core engine (property replacer, filter engine) has been enhanced to support properties from normalized events. Note: this is EXPERIMENTAL code. It is currently know that there are issues if the functionality is used with - disk-based queues - asynchronous action queues You can not use the new functionality together with these features. This limitation will be removed in later releases. However, we preferred to release early, so that one can experiment with the new feature set and accepted the price that this means the full set of functionality is not yet available. If not used together with these features, log normalizing should be pretty stable. - enhanced testing tool tcpflood now supports sending via UDP and the capability to run multiple iterations and generate statistics data records - bugfix: potential abort when output modules with different parameter passing modes were used in configured output modules --------------------------------------------------------------------------- Version 6.1.1 [DEVEL] (rgerhards), 2010-11-30 - bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194 - support for omhdfs officially added (import from 5.7.1) - merged imuxsock improvements from 5.7.1 (see there) - support for systemd officially added (import from 5.7.0) - bugfix: a couple of problems that imfile had on some platforms, namely Ubuntu (not their fault, but occured there) - bugfix: imfile utilizes 32 bit to track offset. Most importantly, this problem can not experienced on Fedora 64 bit OS (which has 64 bit long's!) - a number of other bugfixes from older versions imported --------------------------------------------------------------------------- Version 6.1.0 [DEVEL] (rgerhards), 2010-08-12 *********************************** NOTE ********************************** The v6 versions of rsyslog feature a greatly redesigned config system which, among others, supports scoping. However, the initial version does not contain the whole new system. Rather it will evolve. So it is expected that interfaces, even new ones, break during the initial 6.x.y releases. *********************************** NOTE ********************************** - added $Begin, $End and $ScriptScoping config scope statments (at this time for actions only). - added imptcp, a simplified, Linux-specific and potentielly fast syslog plain tcp input plugin (NOT supporting TLS!) [ported from v4] --------------------------------------------------------------------------- Version 5.10.2 [V5-STABLE], 201?-??-?? - bugfix: queue file size was not correctly processed this could lead to using one queue file per message for sizes >2GiB Thanks to Tomas Heinrich for the patch. - updated systemd files to match current systemd source - bugfix: spurios error messages from imuxsock about (non-error) EAGAIN Thanks to Marius Tomaschewski for the patch. - imklog: added $klogParseKernelTimestamp option When enabled, kernel message [timestamp] is converted for message time. Default is to use receive time as in 5.8.x and before, because the clock used to create the timestamp is not supposed to be as accurate as the monotonic clock (depends on hardware and kernel) resulting in differences between kernel and system messages which occurred at same time. Thanks to Marius Tomaschewski for the patch. - imklog: added $klogKeepKernelTimestamp option When enabled, the kernel [timestamp] remains at begin of each message, even it is used for the message time too. Thanks to Marius Tomaschewski for the patch. - bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds ... actually, they are microseconds. So the fractional part of the timestamp was not properly formatted. Thanks to Marius Tomaschewski for the bug report and the patch idea. - imklog: added $klogKeepKernelTimestamp option When enabled, the kernel [timestamp] remains at begin of each message, even it is used for the message time too. Thanks to Marius Tomaschewski for the patch. - bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds ... actually, they are microseconds. So the fractional part of the timestamp was not properly formatted. Thanks to Marius Tomaschewski for the bug report and the patch idea. - bugfix: invalid DST handling under Solaris Thanks to Scott Severtson for the patch. - bugfix: invalid decrement in pm5424 could lead to log truncation Thanks to Tomas Heinrich for the patch. - bugfix[kind of]: omudpspoof discarded messages >1472 bytes (MTU size) it now truncates these message, but ensures they are sent. Note that 7.3.5+ will switch to fragmented UDP messages instead (up to 64K) --------------------------------------------------------------------------- Version 5.10.1 [V5-STABLE], 2012-10-17 - bugfix: imuxsock and imklog truncated head of received message This happened only under some circumstances. Thanks to Marius Tomaschewski, Florian Piekert and Milan Bartos for their help in solving this issue. - enable DNS resolution in imrelp Thanks to Apollon Oikonomopoulos for the patch - bugfix: invalid property name in property-filter could cause abort if action chaining (& operator) was used http://bugzilla.adiscon.com/show_bug.cgi?id=355 Thanks to pilou@gmx.com for the bug report - bugfix: remove invalid socket option call from imuxsock Thanks to Cristian Ionescu-Idbohrn and Jonny Törnbom - bugfix: fixed wrong bufferlength for snprintf in tcpflood.c when using the -f (dynafiles) option. - fixed issues in build system (namely related to cust1 dummy plugin) --------------------------------------------------------------------------- Version 5.10.0 [V5-STABLE], 2012-08-23 NOTE: this is the new rsyslog v5-stable, incorporating all changes from the 5.9.x series. In addition to that, it contains the fixes and enhancements listed below in this entry. - bugfix: delayble source could block action queue, even if there was a disk queue associated with it. The root cause of this problem was that it makes no sense to delay messages once they arrive in the action queue - the "input" that is being held in that case is the main queue worker, what makes no sense. Thanks to Marcin for alerting us on this problem and providing instructions to reproduce it. - bugfix: disk queue was not persisted on shutdown, regression of fix to http://bugzilla.adiscon.com/show_bug.cgi?id=299 The new code also handles the case of shutdown of blocking light and full delayable sources somewhat smarter and permits, assuming sufficient timouts, to persist message up to the max queue capacity. Also some nits in debug instrumentation have been fixed. - add small delay (50ms) after sending shutdown message There seem to be cases where the shutdown message is otherwise not processed, not even on an idle system. Thanks to Marcin for bringing this problem up. - support for resolving huge groups closes: http://bugzilla.adiscon.com/show_bug.cgi?id=310 Thanks to Alec Warner for the patch - bugfix: potential hang due to mutex deadlock closes: http://bugzilla.adiscon.com/show_bug.cgi?id=316 Thanks to Andreas Piesk for reporting&analyzing this bug as well as providing patches and other help in resolving it. - bugfix: property PROCID empty instead of proper nilvalue if not present If it is not present, it must have the nilvalue "-" as of RFC5424 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=332 Thanks to John N for reporting this issue. - bugfix: "last message repeated n times" message was missing hostname Thanks to Zdenek Salvet for finding this bug and to Bodik for reporting - bugfix: multiple main queues with same queue file name was not detected This lead to queue file corruption. While the root cause is a config error, it is a bug that this important and hard to find config error was not detected by rsyslog. --------------------------------------------------------------------------- Version 5.9.7 [V5-BETA], 2012-05-10 - added capability to specify substrings for field extraction mode - bugfix: ommysql did not properly init/exit the mysql runtime library this could lead to segfaults. Triggering condition: multiple action instances using ommysql. Thanks to Tomas Heinrich for reporting this problem and providing an initial patch (which my solution is based on, I need to add more code to clean the mess up). - bugfix: rsyslog did not terminate when delayable inputs were blocked due to unvailable sources. Fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=299 Thanks to Marcin M for bringing up this problem and Andre Lorbach for helping to reproduce and fix it. - bugfix/tcpflood: sending small test files did not work correctly --------------------------------------------------------------------------- Version 5.9.6 [V5-BETA], 2012-04-12 - added configuration directives to customize queue light delay marks - permit size modifiers (k,m,g,...) in integer config parameters Thanks to Jo Rhett for the suggestion. - bugfix: hostname was not requeried on HUP Thanks to Per Jessen for reporting this bug and Marius Tomaschewski for his help in testing the fix. - bugfix: imklog invalidly computed facility and severity closes: http://bugzilla.adiscon.com/show_bug.cgi?id=313 - bugfix: imptcp input name could not be set config directive was accepted, but had no effect - added configuration directive to disable octet-counted framing for imtcp, directive is $InputTCPServerSupportOctetCountedFraming for imptcp, directive is $InputPTCPServerSupportOctetCountedFraming - added capability to use a local interface IP address as fromhost-ip for locally originating messages. New directive $LocalHostIPIF - added configuration directives to customize queue light delay marks $MainMsgQueueLightDelayMark, $ActionQueueLightDelayMark; both specify number of messages starting at which a delay happens. --------------------------------------------------------------------------- Version 5.9.5 [V5-DEVEL], 2012-01-27 - improved impstats subsystem, added many new counters - enhanced module loader to not rely on PATH_MAX - refactored imklog linux driver, now combined with BSD driver The Linux driver no longer supports outdated kernel symbol resolution, which was disabled by default for very long. Also overall cleanup, resulting in much smaller code. Linux and BSD are now covered by a single small driver. - $IMUXSockRateLimitInterval DEFAULT CHANGED, was 5, now 0 The new default turns off rate limiting. This was chosen as people experienced problems with rate-limiting activated by default. Now it needs an explicit opt-in by setting this parameter. Thanks to Chris Gaffney for suggesting to make it opt-in; thanks to many unnamed others who already had complained at the time Chris made the suggestion ;-) --------------------------------------------------------------------------- Version 5.9.4 [V5-DEVEL], 2011-11-29 - imuxsock: added capability to "annotate" messages with "trusted information", which contains some properties obtained from the system and as such sure to not be faked. This is inspired by the similiar idea introduced in systemd. - removed dependency on gcrypt for recently-enough GnuTLS see: http://bugzilla.adiscon.com/show_bug.cgi?id=289 - bugfix: imuxsock did no longer ignore message-provided timestamp, if so configured (the *default*). Lead to no longer sub-second timestamps. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=281 - bugfix: omfile returns fatal error code for things that go really wrong previously, RS_RET_RESUME was returned, which lead to a loop inside the rule engine as omfile could not really recover. - bugfix: rsyslogd -v always said 64 atomics were not present thanks to mono_matsuko for the patch --------------------------------------------------------------------------- Version 5.9.3 [V5-DEVEL], 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: mark message processing did not work correctly - added capability to emit config error location info for warnings otherwise, omusrmsg's warning about new config format was not accompanied by problem location. - bugfix: potential misadressing in property replacer - bugfix: MSGID corruption in RFC5424 parser under some circumstances closes: http://bugzilla.adiscon.com/show_bug.cgi?id=275 - bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) --------------------------------------------------------------------------- Version 5.9.2 [V5-DEVEL] (rgerhards), 2011-07-11 - systemd support: set stdout/stderr to null - thx to Lennart for the patch - added support for the ":omusrmsg:" syntax in configuring user messages - added support for the ":omfile:" syntax for actions --------------------------------------------------------------------------- Version 5.9.1 [V5-DEVEL] (rgerhards), 2011-06-30 - added support for obtaining timestamp for kernel message from message If the kernel time-stamps messages, time is now take from that timestamp instead of the system time when the message was read. This provides much better accuracy. Thanks to Lennart Poettering for suggesting this feature and his help during implementation. - added support for obtaining timestamp from system for imuxsock This permits to read the time a message was submitted to the system log socket. Most importantly, this is provided in microsecond resolution. So we are able to obtain high precision timestampis even for messages that were - as is usual - not formatted with them. This also simplifies things in regard to local time calculation in chroot environments. Many thanks to Lennart Poettering for suggesting this feature, providing some guidance on implementing it and coordinating getting the necessary support into the Linux kernel. - bugfix: timestamp was incorrectly calculated for timezones with minute offset closes: http://bugzilla.adiscon.com/show_bug.cgi?id=271 - bugfix: problems in failover action handling closes: http://bugzilla.adiscon.com/show_bug.cgi?id=270 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=254 - bugfix: mutex was invalidly left unlocked during action processing At least one case where this can occur is during thread shutdown, which may be initiated by lower activity. In most cases, this is quite unlikely to happen. However, if it does, data structures may be corrupted which could lead to fatal failure and segfault. I detected this via a testbench test, not a user report. But I assume that some users may have had unreproducable aborts that were cause by this bug. - bugfix: memory leak in imtcp & subsystems under some circumstances This leak is tied to error conditions which lead to incorrect cleanup of some data structures. [backport from v6] - bugfix/improvement:$WorkDirectory now gracefully handles trailing slashes --------------------------------------------------------------------------- Version 5.9.0 [V5-DEVEL] (rgerhards), 2011-06-08 - imfile: added $InputFileMaxLinesAtOnce directive - enhanced imfile to support input batching - added capability for imtcp and imptcp to activate keep-alive packets at the socket layer. This has not been added to imttcp, as the latter is only an experimental module, and one which did not prove to be useful. reference: http://kb.monitorware.com/post20791.html - added support to control KEEPALIVE settings in imptcp this has not yet been added to imtcp, but could be done on request. - $ActionName is now also used for naming of queues in impstats as well as in the debug output - bugfix: do not open files with full privileges, if privs will be dropped This make the privilege drop code more bulletproof, but breaks Ubuntu's work-around for log files created by external programs with the wrong user and/or group. Note that it was long said that this "functionality" would break once we go for serious privilege drop code, so hopefully nobody still depends on it (and, if so, they lost...). - bugfix: pipes not opened in full priv mode when privs are to be dropped - this begins a new devel branch for v5 - better handling of queue i/o errors in disk queues. This is kind of a bugfix, but a very intrusive one, this it goes into the devel version first. Right now, "file not found" is handled and leads to the new emergency mode, in which disk action is stopped and the queue run in direct mode. An error message is emited if this happens. - added support for user-level PRI provided via systemd - added new config directive $InputTCPFlowControl to select if tcp received messages shall be flagged as light delayable or not. - enhanced omhdfs to support batching mode. This permits to increase performance, as we now call the HDFS API with much larger message sizes and far more infrequently - bugfix: failover did not work correctly if repeated msg reduction was on affected directive was: $ActionExecOnlyWhenPreviousIsSuspended on closes: http://bugzilla.adiscon.com/show_bug.cgi?id=236 --------------------------------------------------------------------------- Version 5.8.13 [V5-stable] 2012-08-22 - bugfix: DA queue could cause abort - bugfix: "last message repeated n times" message was missing hostname Thanks to Zdenek Salvet for finding this bug and to Bodik for reporting - bugfix "$PreserveFQDN on" was not honored in some modules Thanks to bodik for reporting this bug. - bugfix: randomized IP option header in omudpspoof caused problems closes: http://bugzilla.adiscon.com/show_bug.cgi?id=327 Thanks to Rick Brown for helping to test out the patch. - bugfix: potential abort if output plugin logged message during shutdown note that none of the rsyslog-provided plugins does this Thanks to bodik and Rohit Prasad for alerting us on this bug and analyzing it. fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=347 - bugfix: multiple main queues with same queue file name was not detected This lead to queue file corruption. While the root cause is a config error, it is a bug that this important and hard to find config error was not detected by rsyslog. --------------------------------------------------------------------------- Version 5.8.12 [V5-stable] 2012-06-06 - add small delay (50ms) after sending shutdown message There seem to be cases where the shutdown message is otherwise not processed, not even on an idle system. Thanks to Marcin for bringing this problem up. - support for resolving huge groups closes: http://bugzilla.adiscon.com/show_bug.cgi?id=310 Thanks to Alec Warner for the patch - bugfix: delayble source could block action queue, even if there was a disk queue associated with it. The root cause of this problem was that it makes no sense to delay messages once they arrive in the action queue - the "input" that is being held in that case is the main queue worker, what makes no sense. Thanks to Marcin for alerting us on this problem and providing instructions to reproduce it. - bugfix: disk queue was not persisted on shutdown, regression of fix to http://bugzilla.adiscon.com/show_bug.cgi?id=299 The new code also handles the case of shutdown of blocking light and full delayable sources somewhat smarter and permits, assuming sufficient timouts, to persist message up to the max queue capacity. Also some nits in debug instrumentation have been fixed. - bugfix/omudpspoof: problems, including abort, happend when run on multiple threads. Root cause is that libnet is not thread-safe. omudpspoof now guards libnet calls with their own mutex. - bugfix: if debug message could end up in log file when forking if rsyslog was set to auto-background (thus fork, the default) and debug mode to stdout was enabled, debug messages ended up in the first log file opened. Currently, stdout logging is completely disabled in forking mode (but writing to the debug log file is still possible). This is a change in behaviour, which is under review. If it causes problems to you, please let us know. Thanks to Tomas Heinrich for the patch. - bugfix/tcpflood: sending small test files did not work correctly - bugfix: potential hang due to mutex deadlock closes: http://bugzilla.adiscon.com/show_bug.cgi?id=316 Thanks to Andreas Piesk for reporting&analyzing this bug as well as providing patches and other help in resolving it. - bugfix: property PROCID empty instead of proper nilvalue if not present If it is not present, it must have the nilvalue "-" as of RFC5424 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=332 Thanks to John N for reporting this issue. --------------------------------------------------------------------------- Version 5.8.11 [V5-stable] 2012-05-03 - bugfix: ommysql did not properly init/exit the mysql runtime library this could lead to segfaults. Triggering condition: multiple action instances using ommysql. Thanks to Tomas Heinrich for reporting this problem and providing an initial patch (which my solution is based on, I need to add more code to clean the mess up). - bugfix: rsyslog did not terminate when delayable inputs were blocked due to unvailable sources. Fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=299 Thanks to Marcin M for bringing up this problem and Andre Lorbach for helping to reproduce and fix it. - bugfix: active input in "light delay state" could block rsyslog termination, at least for prolonged period of time - bugfix: imptcp input name could not be set config directive was accepted, but had no effect - bugfix: assigned ruleset was lost when using disk queues This looked quite hard to diagnose for disk-assisted queues, as the pure memory part worked well, but ruleset info was lost for messages stored inside the disk queue. - bugfix: hostname was not requeried on HUP Thanks to Per Jessen for reporting this bug and Marius Tomaschewski for his help in testing the fix. - bugfix: inside queue.c, some thread cancel states were not correctly reset. While this is a bug, we assume it did have no practical effect because the reset as it was done was set to the state the code actually had at this point. But better fix this... --------------------------------------------------------------------------- Version 5.8.10 [V5-stable] 2012-04-05 - bugfix: segfault on startup if $actionqueuefilename was missing for disk queue config Thanks to Tomas Heinrich for the patch. - bugfix: segfault if disk-queue was started up with old queue file Thanks to Tomas Heinrich for the patch. - bugfix: memory leak in array passing output module mode --------------------------------------------------------------------------- Version 5.8.9 [V5-stable] 2012-03-15 - added tool to recover disk queue if .qi file is missing (recover_qi.pl) Thanks to Kaiwang Chen for contributing this tool - bugfix: stopped DA queue was never processed after a restart due to a regression from statistics module - added better doc for statsobj interface Thanks to Kaiwang Chen for his suggestions and analysis in regard to the stats subsystem. --------------------------------------------------------------------------- Version 5.8.8 [V5-stable] 2012-03-05 - added capability to use a local interface IP address as fromhost-ip for imuxsock imklog new config directives: $IMUXSockLocalIPIF, $klogLocalIPIF - added configuration directives to customize queue light delay marks $MainMsgQueueLightDelayMark, $ActionQueueLightDelayMark; both specify number of messages starting at which a delay happens. - bugfix: omprog made rsyslog abort on startup if not binary to execute was configured - bugfix: imklog invalidly computed facility and severity closes: http://bugzilla.adiscon.com/show_bug.cgi?id=313 --------------------------------------------------------------------------- Version 5.8.7 [V5-stable] 2012-01-17 - bugfix: instabilities when using RFC5424 header fields Thanks to Kaiwang Chen for the patch - bugfix: imuxsock did truncate part of received message if it did not contain a proper date. The truncation occured because we removed that part of the messages that was expected to be the date. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=295 - bugfix: potential abort after reading invalid X.509 certificate closes: http://bugzilla.adiscon.com/show_bug.cgi?id=290 Thanks to Tomas Heinrich for the patch - bugfix: stats counter were not properly initialized on creation - FQDN hostname for multihomed host was not always set to the correct name if multiple aliases existed. Thanks to Tomas Heinreich for the patch. - re-licensed larger parts of the codebase under the Apache license 2.0 --------------------------------------------------------------------------- Version 5.8.6 [V5-stable] 2011-10-21 - bugfix: missing whitespace after property-based filter was not detected - bugfix: $OMFileFlushInterval period was doubled - now using correct value - bugfix: ActionQueue could malfunction due to index error Thanks to Vlad Grigorescu for the patch - bugfix: $ActionExecOnlyOnce interval did not work properly Thanks to Tomas Heinrich for the patch - bugfix: race condition when extracting program name, APPNAME, structured data and PROCID (RFC5424 fields) could lead to invalid characters e.g. in dynamic file names or during forwarding (general malfunction of these fields in templates, mostly under heavy load) - bugfix: imuxsock did no longer ignore message-provided timestamp, if so configured (the *default*). Lead to no longer sub-second timestamps. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=281 - bugfix: omfile returns fatal error code for things that go really wrong previously, RS_RET_RESUME was returned, which lead to a loop inside the rule engine as omfile could not really recover. - bugfix: imfile did invalid system call under some circumstances when a file that was to be monitored did not exist BUT the state file actually existed. Mostly a cosmetic issue. Root cause was incomplete error checking in stream.c; so patch may affect other code areas. - bugfix: rsyslogd -v always said 64 atomics were not present thanks to mono_matsuko for the patch --------------------------------------------------------------------------- Version 5.8.5 [V5-stable] (rgerhards/al), 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: mark message processing did not work correctly - bugfix: potential hang condition during tag emulation - bugfix: too-early string termination during tag emulation - bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) - bugfix: fixed incorrect state handling for Discard Action (transactions) Note: This caused all messages in a batch to be set to COMMITTED, even if they were discarded. --------------------------------------------------------------------------- Version 5.8.4 [V5-stable] (al), 2011-08-10 - bugfix: potential misadressing in property replacer - bugfix: memcpy overflow can occur in allowed sender checkig if a name is resolved to IPv4-mapped-on-IPv6 address Found by Ismail Dönmez at suse - bugfix: potential misadressing in property replacer - bugfix: MSGID corruption in RFC5424 parser under some circumstances closes: http://bugzilla.adiscon.com/show_bug.cgi?id=275 --------------------------------------------------------------------------- Version 5.8.3 [V5-stable] (rgerhards), 2011-07-11 - systemd support: set stdout/stderr to null - thx to Lennart for the patch - added support for the ":omusrmsg:" syntax in configuring user messages - added support for the ":omfile:" syntax for actions Note: previous outchannel syntax will generate a warning message. This may be surprising to some users, but it is quite urgent to alert them of the new syntax as v6 can no longer support the previous one. --------------------------------------------------------------------------- Version 5.8.2 [V5-stable] (rgerhards), 2011-06-21 - bugfix: problems in failover action handling closes: http://bugzilla.adiscon.com/show_bug.cgi?id=270 closes: http://bugzilla.adiscon.com/show_bug.cgi?id=254 - bugfix: mutex was invalidly left unlocked during action processing At least one case where this can occur is during thread shutdown, which may be initiated by lower activity. In most cases, this is quite unlikely to happen. However, if it does, data structures may be corrupted which could lead to fatal failure and segfault. I detected this via a testbench test, not a user report. But I assume that some users may have had unreproducable aborts that were cause by this bug. - bugfix: memory leak in imtcp & subsystems under some circumstances This leak is tied to error conditions which lead to incorrect cleanup of some data structures. [backport from v6] - bugfix/improvement:$WorkDirectory now gracefully handles trailing slashes --------------------------------------------------------------------------- Version 5.8.1 [V5-stable] (rgerhards), 2011-05-19 - bugfix: invalid processing in QUEUE_FULL condition If the the multi-submit interface was used and a QUEUE_FULL condition occured, the failed message was properly destructed. However, the rest of the input batch, if it existed, was not processed. So this lead to potential loss of messages and a memory leak. The potential loss of messages was IMHO minor, because they would have been dropped in most cases due to the queue remaining full, but very few lucky ones from the batch may have made it. Anyhow, this has now been changed so that the rest of the batch is properly tried to be enqueued and, if not possible, destructed. - new module mmsnmptrapd, a sample message modification module This can be useful to reformat snmptrapd messages and also serves as a sample for how to write message modification modules using the output module interface. Note that we introduced this new functionality directly into the stable release, as it does not modify the core and as such cannot have any side-effects if it is not used (and thus the risk is solely on users requiring that functionality). - bugfix: rate-limiting inside imuxsock did not work 100% correct reason was that a global config variable was invalidly accessed where a listener variable should have been used. Also performance-improved the case when rate limiting is turned off (this is a very unintrusive change, thus done directly to the stable version). - bugfix: $myhostname not available in RainerScript (and no error message) closes: http://bugzilla.adiscon.com/show_bug.cgi?id=233 - bugfix: memory and file descriptor leak in stream processing Leaks could occur under some circumstances if the file stream handler errored out during the open call. Among others, this could cause very big memory leaks if there were a problem with unreadable disk queue files. In regard to the memory leak, this closes: http://bugzilla.adiscon.com/show_bug.cgi?id=256 - bugfix: doc for impstats had wrong config statements also, config statements were named a bit inconsistent, resolved that problem by introducing an alias and only documenting the consistent statements Thanks to Marcin for bringing up this problem. - bugfix: IPv6-address could not be specified in omrelp this was due to improper parsing of ":" closes: http://bugzilla.adiscon.com/show_bug.cgi?id=250 - bugfix: TCP connection invalidly aborted when messages needed to be discarded (due to QUEUE_FULL or similar problem) - bugfix: $LocalHostName was not honored under all circumstances closes: http://bugzilla.adiscon.com/show_bug.cgi?id=258 - bugfix(minor): improper template function call in syslogd.c --------------------------------------------------------------------------- Version 5.8.0 [V5-stable] (rgerhards), 2011-04-12 This is the new v5-stable branch, importing all feature from the 5.7.x versions. To see what has changed in regard to the previous v5-stable, check the Changelog for 5.7.x below. - bugfix: race condition in deferred name resolution closes: http://bugzilla.adiscon.com/show_bug.cgi?id=238 Special thanks to Marcin for his persistence in helping to solve this bug. - bugfix: DA queue was never shutdown once it was started closes: http://bugzilla.adiscon.com/show_bug.cgi?id=241 --------------------------------------------------------------------------- Version 5.7.10 [V5-BETA] (rgerhards), 2011-03-29 - bugfix: ompgsql did not work properly with ANSI SQL strings closes: http://bugzilla.adiscon.com/show_bug.cgi?id=229 - bugfix: rsyslog did not build with --disable-regexp configure option closes: http://bugzilla.adiscon.com/show_bug.cgi?id=243 - bugfix: PRI was invalid on Solaris for message from local log socket - enhance: added $BOM system property to ease writing byte order masks - bugfix: RFC5424 parser confused by empty structured data closes: http://bugzilla.adiscon.com/show_bug.cgi?id=237 - bugfix: error return from strgen caused abort, now causes action to be ignored (just like a failed filter) - new sample plugin for a strgen to generate sql statement consumable by a database plugin - bugfix: strgen could not be used together with database outputs because the sql/stdsql option could not be specified. This has been solved by permitting the strgen to include the opton inside its name. closes: http://bugzilla.adiscon.com/show_bug.cgi?id=195 --------------------------------------------------------------------------- Version 5.7.9 [V5-BETA] (rgerhards), 2011-03-16 - improved testbench among others, life tests for ommysql (against a test database) have been added, valgrind-based testing enhanced, ... - enhance: fallback *at runtime* to epoll_create if epoll_create1 is not available. Thanks to Michael Biebl for analysis and patch! - bugfix: failover did not work correctly if repeated msg reduction was on closes: http://bugzilla.adiscon.com/show_bug.cgi?id=236 affected directive was: $ActionExecOnlyWhenPreviousIsSuspended on - bugfix: minor memory leak in omlibdbi (< 1k per instance and run) - bugfix: (regression) omhdfs did no longer compile - bugfix: omlibdbi did not use password from rsyslog.conf closes: http://bugzilla.adiscon.com/show_bug.cgi?id=203 --------------------------------------------------------------------------- Version 5.7.8 [V5-BETA] (rgerhards), 2011-03-09 - systemd support somewhat improved (can now take over existing log sockt) - bugfix: discard action did not work under some circumstances fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=217 - bugfix: file descriptor leak in gnutls netstream driver fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=222 --------------------------------------------------------------------------- Version 5.7.7 [V5-BETA] (rgerhards), 2011-03-02 - bugfix: potential abort condition when $RepeatedMsgReduction set to on as well as potentially in a number of other places where MsgDup() was used. This only happened when the imudp input module was used and it depended on name resolution not yet had taken place. In other words, this was a strange problem that could lead to hard to diagnose instability. So if you experience instability, chances are good that this fix will help. --------------------------------------------------------------------------- Version 5.7.6 [V5-BETA] (rgerhards), 2011-02-25 - bugfix: fixed a memory leak and potential abort condition this could happen if multiple rulesets were used and some output batches contained messages belonging to more than one ruleset. fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=226 fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=218 - bugfix: memory leak when $RepeatedMsgReduction on was used bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=225 --------------------------------------------------------------------------- Version 5.7.5 [V5-BETA] (rgerhards), 2011-02-23 - enhance: imfile did not yet support multiple rulesets, now added we do this directly in the beta because a) it does not affect existing functionality and b) one may argue that this missing functionality is close to a bug. - improved testbench, added tests for imuxsock - bugfix: imuxsock did no longer sanitize received messages This was a regression from the imuxsock partial rewrite. Happened because the message is no longer run through the standard parsers. bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=224 - bugfix: minor race condition in action.c - considered cosmetic This is considered cosmetic as multiple threads tried to write exactly the same value into the same memory location without sync. The method has been changed so this can no longer happen. --------------------------------------------------------------------------- Version 5.7.4 [V5-BETA] (rgerhards), 2011-02-17 - added pmsnare parser module (written by David Lang) - enhanced imfile to support non-cancel input termination - improved systemd socket activation thanks to Marius Tomaschewski - improved error reporting for $WorkDirectory non-existance and other detectable problems are now reported, and the work directory is NOT set in this case - bugfix: pmsnare causded abort under some conditions - bugfix: abort if imfile reads file line of more than 64KiB Thanks to Peter Eisentraut for reporting and analysing this problem. bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=221 - bugfix: queue engine did not properly slow down inputs in FULL_DELAY mode when in disk-assisted mode. This especially affected imfile, which created unnecessarily queue files if a large set of input file data was to process. - bugfix: very long running actions could prevent shutdown under some circumstances. This has now been solved, at least for common situations. - bugfix: fixed compile problem due to empty structs this occured only on some platforms/compilers. thanks to Dražen Kačar for the fix --------------------------------------------------------------------------- Version 5.7.3 [V5-BETA] (rgerhards), 2011-02-07 - added support for processing multi-line messages in imfile - added $IMUDPSchedulingPolicy and $IMUDPSchedulingPriority config settings - added $LocalHostName config directive - bugfix: fixed build problems on some platforms namely those that have 32bit atomic operations but not 64 bit ones - bugfix: local hostname was pulled too-early, so that some config directives (namely FQDN settings) did not have any effect - bugfix: imfile did duplicate messages under some circumstances - added $OMMySQLConfigFile config directive - added $OMMySQLConfigSection config directive --------------------------------------------------------------------------- Version 5.7.2 [V5-DEVEL] (rgerhards), 2010-11-26 - bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194 - bugfix: imfile state file was not written when relative file name for it was specified - bugfix: compile failed on systems without epoll_create1() Thanks to David Hill for providing a fix. - bugfix: atomic increment for msg object may not work correct on all platforms. Thanks to Chris Metcalf for the patch - bugfix: replacements for atomic operations for non-int sized types had problems. At least one instance of that problem could potentially lead to abort (inside omfile). --------------------------------------------------------------------------- Version 5.7.1 [V5-DEVEL] (rgerhards), 2010-10-05 - support for Hadoop's HDFS added (via omhdfs) - imuxsock now optionally use SCM_CREDENTIALS to pull the pid from the log socket itself (thanks to Lennart Poettering for the suggesting this feature) - imuxsock now optionally uses per-process input rate limiting, guarding the user against processes spamming the system log (thanks to Lennart Poettering for suggesting this feature) - added new config statements * $InputUnixListenSocketUsePIDFromSystem * $SystemLogUsePIDFromSystem * $SystemLogRateLimitInterval * $SystemLogRateLimitBurst * $SystemLogRateLimitSeverity * $IMUxSockRateLimitInterval * $IMUxSockRateLimitBurst * $IMUxSockRateLimitSeverity - imuxsock now supports up to 50 different sockets for input - some code cleanup in imuxsock (consider this a release a major modification, especially if problems show up) - bugfix: /dev/log was unlinked even when passed in from systemd in which case it should be preserved as systemd owns it --------------------------------------------------------------------------- Version 5.7.0 [V5-DEVEL] (rgerhards), 2010-09-16 - added module impstat to emit periodic statistics on rsyslog counters - support for systemd officially added * acquire /dev/log socket optionally from systemd thanks to Lennart Poettering for this patch * sd-systemd API added as part of rsyslog runtime library --------------------------------------------------------------------------- Version 5.6.5 [V5-STABLE] (rgerhards), 2011-03-22 - bugfix: failover did not work correctly if repeated msg reduction was on affected directive was: $ActionExecOnlyWhenPreviousIsSuspended on closes: http://bugzilla.adiscon.com/show_bug.cgi?id=236 - bugfix: omlibdbi did not use password from rsyslog.con closes: http://bugzilla.adiscon.com/show_bug.cgi?id=203 - bugfix(kind of): tell users that config graph can currently not be generated closes: http://bugzilla.adiscon.com/show_bug.cgi?id=232 - bugfix: discard action did not work under some circumstances fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=217 (backport from 5.7.8) --------------------------------------------------------------------------- Version 5.6.4 [V5-STABLE] (rgerhards), 2011-03-03 - bugfix: potential abort condition when $RepeatedMsgReduction set to on as well as potentially in a number of other places where MsgDup() was used. This only happened when the imudp input module was used and it depended on name resolution not yet had taken place. In other words, this was a strange problem that could lead to hard to diagnose instability. So if you experience instability, chances are good that this fix will help. - bugfix: fixed a memory leak and potential abort condition this could happen if multiple rulesets were used and some output batches contained messages belonging to more than one ruleset. fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=226 fixes: http://bugzilla.adiscon.com/show_bug.cgi?id=218 - bugfix: memory leak when $RepeatedMsgReduction on was used bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=225 --------------------------------------------------------------------------- Version 5.6.3 [V5-STABLE] (rgerhards), 2011-01-26 - bugfix: action processor released memory too early, resulting in potential issue in retry cases (but very unlikely due to another bug, which I also fixed -- only after the fix this problem here became actually visible). - bugfix: batch processing flagged invalid message as "bad" under some circumstances - bugfix: unitialized variable could cause issues under extreme conditions plus some minor nits. This was found after a clang static code analyzer analysis (great tool, and special thanks to Marcin for telling me about it!) - bugfix: batches which had actions in error were not properly retried in all cases - bugfix: imfile did duplicate messages under some circumstances - bugfix: testbench was not activated if no Java was present on system ... what actually was a left-over. Java is no longer required. --------------------------------------------------------------------------- Version 5.6.2 [V5-STABLE] (rgerhards), 2010-11-30 - bugfix: compile failed on systems without epoll_create1() Thanks to David Hill for providing a fix. - bugfix: atomic increment for msg object may not work correct on all platforms. Thanks to Chris Metcalf for the patch - bugfix: replacements for atomic operations for non-int sized types had problems. At least one instance of that problem could potentially lead to abort (inside omfile). - added the $InputFilePersistStateInterval config directive to imfile - changed imfile so that the state file is never deleted (makes imfile more robust in regard to fatal failures) - bugfix: a slightly more informative error message when a TCP connections is aborted --------------------------------------------------------------------------- Version 5.6.1 [V5-STABLE] (rgerhards), 2010-11-24 - bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194 - permitted imptcp to work on systems which support epoll(), but not epoll_create(). Bug: http://bugzilla.adiscon.com/show_bug.cgi?id=204 Thanks to Nicholas Brink for reporting this problem. - bugfix: testbench failed if imptcp was not enabled - bugfix: segfault when an *empty* template was used Bug: http://bugzilla.adiscon.com/show_bug.cgi?id=206 Thanks to David Hill for alerting us. - bugfix: compile failed with --enable-unlimited-select thanks varmojfekoj for the patch --------------------------------------------------------------------------- Version 5.6.0 [V5-STABLE] (rgerhards), 2010-10-19 This release brings all changes and enhancements of the 5.5.x series to the v5-stable branch. - bugfix: a couple of problems that imfile had on some platforms, namely Ubuntu (not their fault, but occured there) - bugfix: imfile utilizes 32 bit to track offset. Most importantly, this problem can not experienced on Fedora 64 bit OS (which has 64 bit long's!) --------------------------------------------------------------------------- Version 5.5.7 [V5-BETA] (rgerhards), 2010-08-09 - changed omudpspoof default spoof address to simplify typical use case thanks to David Lang for suggesting this - doc bugfix: pmlastmsg doc samples had errors - bugfix[minor]: pmrfc3164sd had invalid name (resided in rsyslog name space, what should not be the case for a contributed module) - added omuxsock, which permits to write message to local Unix sockets this is the counterpart to imuxsock, enabling fast local forwarding --------------------------------------------------------------------------- Version 5.5.6 [DEVEL] (rgerhards), 2010-07-21 - added parser modules * pmlastmsg, which supports the notoriously malformed "last message repeated n times" messages from some syslogd's (namely sysklogd) * pmrfc3164sd (contributed), supports RFC5424 structured data in RFC3164 messages [untested] - added new module type "string generator", used to speed up output processing. Expected speedup for (typical) rsyslog processing is roughly 5 to 6 percent compared to using string-based templates. They may also be used to do more complex formatting with custom C code, what provided greater flexibility and probably far higher speed, for example if using multiple regular expressions within a template. - added 4 string generators for * RSYSLOG_FileFormat * RSYSLOG_TraditionalFileFormat * RSYSLOG_ForwardFormat * RSYSLOG_TraditionalForwardFormat - bugfix: mutexes used to simulate atomic instructions were not destructed - bugfix: regression caused more locking action in msg.c than necessary - bugfix: "$ActionExecOnlyWhenPreviousIsSuspended on" was broken - bugfix: segfault on HUP when "HUPIsRestart" was set to "on" thanks varmojfekoj for the patch - bugfix: default for $OMFileFlushOnTXEnd was wrong ("off"). This, in default mode, caused buffered writing to be used, what means that it looked like no output were written or partial lines. Thanks to Michael Biebl for pointing out this bug. - bugfix: programname filter in ! configuration can not be reset Thanks to Kiss Gabor for the patch. --------------------------------------------------------------------------- Version 5.5.5 [DEVEL] (rgerhards), 2010-05-20 - added new cancel-reduced action thread termination method We now manage to cancel threads that block inside a retry loop to terminate without the need to cancel the thread. Avoiding cancellation helps keep the system complexity minimal and thus provides for better stability. This also solves some issues with improper shutdown when inside an action retry loop. --------------------------------------------------------------------------- Version 5.5.4 [DEVEL] (rgerhards), 2010-05-03 - This version offers full support for Solaris on Intel and Sparc - bugfix: problems with atomic operations emulation replaced atomic operation emulation with new code. The previous code seemed to have some issue and also limited concurrency severely. The whole atomic operation emulation has been rewritten. - bugfix: netstream ptcp support class was not correctly build on systems without epoll() support - bugfix: segfault on Solaris/Sparc --------------------------------------------------------------------------- Version 5.5.3 [DEVEL] (rgerhards), 2010-04-09 - added basic but functional support for Solaris - imported many bugfixes from 3.6.2/4.6.1 (see ChangeLog below!) - added new property replacer option "date-rfc3164-buggyday" primarily to ease migration from syslog-ng. See property replacer doc for details. - added capability to turn off standard LF delimiter in TCP server via new directive "$InputTCPServerDisableLFDelimiter on" - bugfix: failed to compile on systems without epoll support - bugfix: comment char ('#') in literal terminated script parsing and thus could not be used. but tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=119 [merged in from v3.22.2] - imported patches from 4.6.0: * improved testbench to contain samples for totally malformed messages which miss parts of the message content * bugfix: some malformed messages could lead to a missing LF inside files or some other missing parts of the template content. * bugfix: if a message ended immediately with a hostname, the hostname was mistakenly interpreted as TAG, and localhost be used as hostname --------------------------------------------------------------------------- Version 5.5.2 [DEVEL] (rgerhards), 2010-02-05 - applied patches that make rsyslog compile under Apple OS X. Thanks to trey for providing these. - replaced data type "bool" by "sbool" because this created some portability issues. - added $Escape8BitCharactersOnReceive directive Thanks to David Lang for suggesting it. - worked around an issue where omfile failed to compile on 32 bit platforms under some circumstances (this smells like a gcc problem, but a simple solution was available). Thanks to Kenneth Marshall for some advice. - extended testbench --------------------------------------------------------------------------- Version 5.5.1 [DEVEL] (rgerhards), 2009-11-27 - introduced the ablity for netstream drivers to utilize an epoll interface This offers increased performance and removes the select() FDSET size limit from imtcp. Note that we fall back to select() if there is no epoll netstream drivers. So far, an epoll driver has only been implemented for plain tcp syslog, the rest will follow once the code proves well in practice AND there is demand. - re-implemented $EscapeControlCharacterTab config directive Based on Jonathan Bond-Caron's patch for v4. This now also includes some automatted tests. - bugfix: enabling GSSServer crashes rsyslog startup Thanks to Tomas Kubina for the patch [imgssapi] - bugfix (kind of): check if TCP connection is still alive if using TLS Thanks to Jonathan Bond-Caron for the patch. --------------------------------------------------------------------------- Version 5.5.0 [DEVEL] (rgerhards), 2009-11-18 - moved DNS resolution code out of imudp and into the backend processing Most importantly, DNS resolution now never happens if the resolved name is not required. Note that this applies to imudp - for the other inputs, DNS resolution almost comes for free, so we do not do it there. However, the new method has been implemented in a generic way and as such may also be used by other modules in the future. - added option to use unlimited-size select() calls Thanks to varmjofekoj for the patch This is not done in imudp, as it natively supports epoll(). - doc: improved description of what loadable modules can do --------------------------------------------------------------------------- Version 5.4.2 [v5-stable] (rgerhards), 2010-03-?? - bugfix(kind of): output plugin retry behaviour could cause engine to loop The rsyslog engine did not guard itself against output modules that do not properly convey back the tryResume() behaviour. This then leads to what looks like an endless loop. I consider this to be a bug of the engine not only because it should be hardened against plugin misbehaviour, but also because plugins may not be totally able to avoid this situation (depending on the type of and processing done by the plugin). - bugfix: testbench failed when not executed in UTC+1 timezone accidently, the time zone information was kept inside some to-be-checked-for responses - temporary bugfix replaced by permanent one for message-induced off-by-one error (potential segfault) (see 4.6.2) The analysis has been completed and a better fix been crafted and integrated. - bugfix(minor): status variable was uninitialized However, this would have caused harm only if NO parser modules at all were loaded, which would lead to a defunctional configuration at all. And, even more important, this is impossible as two parser modules are built-in and thus can not be "not loaded", so we always have a minimum of two. --------------------------------------------------------------------------- Version 5.4.1 [v5-stable] (rgerhards), 2010-03-?? - added new property replacer option "date-rfc3164-buggyday" primarily to ease migration from syslog-ng. See property replacer doc for details. [backport from 5.5.3 because urgently needed by some] - imported all bugfixes vom 4.6.2 (see below) --------------------------------------------------------------------------- Version 5.4.0 [v5-stable] (rgerhards), 2010-03-08 *************************************************************************** * This is a new stable v5 version. It contains all fixes and enhancements * * made during the 5.3.x phase as well as those listed below. * * Note that the 5.2.x series was quite buggy and as such all users are * * strongly advised to upgrade to 5.4.0. * *************************************************************************** - bugfix: omruleset failed to work in many cases bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=179 Thanks to Ryan B. Lynch for reporting this issue. - bugfix: comment char ('#') in literal terminated script parsing and thus could not be used. but tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=119 [merged in from v3.22.2] --------------------------------------------------------------------------- Version 5.3.7 [BETA] (rgerhards), 2010-01-27 - bugfix: queues in direct mode could case a segfault, especially if an action failed for action queues. The issue was an invalid increment of a stack-based pointer which lead to destruction of the stack frame and thus a segfault on function return. Thanks to Michael Biebl for alerting us on this problem. - bugfix: hostname accidently set to IP address for some message sources, for example imudp. Thanks to Anton for reporting this bug. [imported v4] - bugfix: ompgsql had problems with transaction support, what actually rendered it unsuable. Thanks to forum user "horhe" for alerting me on this bug and helping to debug/fix it! [imported from 5.3.6] - bugfix: $CreateDirs variable not properly initialized, default thus was random (but most often "on") [imported from v3] - bugfix: potential segfaults during queue shutdown (bugs require certain non-standard settings to appear) Thanks to varmojfekoj for the patch [imported from 4.5.8] [backport from 5.5.2] - bugfix: wrong memory assignment for a config variable (probably without causing any harm) [backport from 5.2.2] - bugfix: rsyslog hangs when writing to a named pipe which nobody was reading. Thanks to Michael Biebl for reporting this bug. Bugzilla entry: http://bugzilla.adiscon.com/show_bug.cgi?id=169 [imported from 4.5.8] --------------------------------------------------------------------------- Version 5.3.6 [BETA] (rgerhards), 2010-01-13 - bugfix: ompgsql did not properly check the server connection in tryResume(), which could lead to rsyslog running in a thight loop - bugfix: suspension during beginTransaction() was not properly handled by rsyslog core - bugfix: omfile output was only written when buffer was full, not at end of transaction - bugfix: commit transaction was not properly conveyed to message layer, potentially resulting in non-message destruction and thus hangs - bugfix: enabling GSSServer crashes rsyslog startup Thanks to Tomas Kubina for the patch [imgssapi] - bugfix (kind of): check if TCP connection is still alive if using TLS Thanks to Jonathan Bond-Caron for the patch. - bugfix: $CreateDirs variable not properly initialized, default thus was random (but most often "on") [imported from v3] - bugfix: ompgsql had problems with transaction support, what actually rendered it unsuable. Thanks to forum user "horhe" for alerting me on this bug and helping to debug/fix it! - bugfix: memory leak when sending messages in zip-compressed format Thanks to Naoya Nakazawa for analyzing this issue and providing a patch. - worked around an issue where omfile failed to compile on 32 bit platforms under some circumstances (this smells like a gcc problem, but a simple solution was available). Thanks to Kenneth Marshall for some advice. [backported from 5.5.x branch] --------------------------------------------------------------------------- Version 5.3.5 [BETA] (rgerhards), 2009-11-13 - some light performance enhancement by replacing time() call with much faster (at least under linux) gettimeofday() calls. - some improvement of omfile performance with dynafiles saved costly time() calls by employing a logical clock, which is sufficient for the use case - bugfix: omudpspoof miscalculated source and destination ports while this was probably not noticed for source ports, it resulted in almost all destination ports being wrong, except for the default port of 514, which by virtue of its binary representation was calculated correct (and probably thus the bug not earlier detected). - bugfixes imported from earlier releases * bugfix: named pipes did no longer work (they always got an open error) this was a regression from the omfile rewrite in 4.5.0 * bugfix(testbench): sequence check was not always performed correctly, that could result in tests reporting success when they actually failed - improved testbench: added tests for UDP forwarding and omudpspoof - doc bugfix: omudpspoof had wrong config command names ("om" missing) - bugfix [imported from 4.4.3]: $ActionExecOnlyOnceEveryInterval did not work. - [inport v4] improved testbench, contains now tcp and gzip test cases - [import v4] added a so-called "On Demand Debug" mode, in which debug output can be generated only after the process has started, but not right from the beginning. This is assumed to be useful for hard-to-find bugs. Also improved the doc on the debug system. - bugfix: segfault on startup when -q or -Q option was given [imported from v3-stable] --------------------------------------------------------------------------- Version 5.3.4 [DEVEL] (rgerhards), 2009-11-04 - added the ability to create custom message parsers - added $RulesetParser config directive that permits to bind specific parsers to specific rulesets - added omruleset output module, which provides great flexibility in action processing. THIS IS A VERY IMPORTANT ADDITION, see its doc for why. - added the capability to have ruleset-specific main message queues This offers considerable additional flexibility AND superior performance (in cases where multiple inputs now can avoid lock contention) - bugfix: correct default for escape ('#') character restored This was accidently changed to '\\', thanks to David Lang for reporting - bugfix(testbench): testcase did not properly wait for rsyslogd shutdown thus some unpredictable behavior and a false negative test result could occur. --------------------------------------------------------------------------- Version 5.3.3 [DEVEL] (rgerhards), 2009-10-27 - simplified and thus speeded up the queue engine, also fixed some potential race conditions (in very unusual shutdown conditions) along the way. The threading model has seriously changes, so there may be some regressions. - enhanced test environment (inlcuding testbench): support for enhancing probability of memory addressing failure by using non-NULL default value for malloced memory (optional, only if requested by configure option). This helps to track down some otherwise undetected issues within the testbench. - bugfix: potential abort if inputname property was not set primarily a problem of imdiag - bugfix: message processing states were not set correctly in all cases however, this had no negative effect, as the message processing state was not evaluated when a batch was deleted, and that was the only case where the state could be wrong. --------------------------------------------------------------------------- Version 5.3.2 [DEVEL] (rgerhards), 2009-10-21 - enhanced omfile to support transactional interface. This will increase performance in many cases. - added multi-ruleset support to imudp - re-enabled input thread termination handling that does avoid thread cancellation where possible. This provides a more reliable mode of rsyslogd termination (canceling threads my result in not properly freed resouces and potential later hangs, even though we perform proper cancel handling in our code). This is part of an effort to reduce thread cancellation as much as possible in rsyslog. NOTE: the code previously written code for this functionality had a subtle race condition. The new code solves that. - enhanced immark to support non-cancel input module termination - improved imudp so that epoll can be used in more environments, fixed potential compile time problem if EPOLL_CLOEXEC is not available. - some cleanup/slight improvement: * changed imuxsock to no longer use deprecated submitAndParseMsg() IF * changed submitAndParseMsg() interface to be a wrapper around the new way of message creation/submission. This enables older plugins to be used together with the new interface. The removal also enables us to drop a lot of duplicate code, reducing complexity and increasing maintainability. - bugfix: segfault when starting up with an invalid .qi file for a disk queue Failed for both pure disk as well as DA queues. Now, we emit an error message and disable disk queueing facility. - bugfix: potential segfault on messages with empty MSG part. This was a recently introduced regression. - bugfix: debug string larger than 1K were improperly displayed. Max size is now 32K, and if a string is even longer it is meaningfully truncated. --------------------------------------------------------------------------- Version 5.3.1 [DEVEL] (rgerhards), 2009-10-05 - added $AbortOnUncleanConfig directive - permits to prevent startup when there are problems with the configuration file. See it's doc for details. - included some important fixes from v4-stable: * bugfix: invalid handling of zero-sized messages * bugfix: zero-sized UDP messages are no longer processed * bugfix: random data could be appended to message * bugfix: reverse lookup reduction logic in imudp do DNS queries too often - bugfixes imported from 4.5.4: * bugfix: potential segfault in stream writer on destruction * bugfix: potential race in object loader (obj.c) during use/release * bugfixes: potential problems in out file zip writer --------------------------------------------------------------------------- Version 5.3.0 [DEVEL] (rgerhards), 2009-09-14 - begun to add simple GUI programs to gain insight into running rsyslogd instances and help setup and troubleshooting (active via the --enable-gui ./configure switch) - changed imudp to utilize epoll(), where available. This shall provide slightly better performance (just slightly because we called select() rather infrequently on a busy system) --------------------------------------------------------------------------- Version 5.2.2 [v5-stable] (rgerhards), 2009-11-?? - bugfix: enabling GSSServer crashes rsyslog startup Thanks to Tomas Kubina for the patch [imgssapi] --------------------------------------------------------------------------- Version 5.2.1 [v5-stable] (rgerhards), 2009-11-02 - bugfix [imported from 4.4.3]: $ActionExecOnlyOnceEveryInterval did not work. - bugfix: segfault on startup when -q or -Q option was given [imported from v3-stable] --------------------------------------------------------------------------- Version 5.2.0 [v5-stable] (rgerhards), 2009-11-02 This is a re-release of version 5.1.6 as stable after we did not get any bug reports during the whole beta phase. Still, this first v5-stable may not be as stable as one hopes for, I am not sure if we did not get bug reports just because nobody tried it. Anyhow, we need to go forward and so we have the initial v5-stable. --------------------------------------------------------------------------- Version 5.1.6 [v5-beta] (rgerhards), 2009-10-15 - feature imports from v4.5.6 - bugfix: potential race condition when queue worker threads were terminated - bugfix: solved potential (temporary) stall of messages when the queue was almost empty and few new data added (caused testbench to sometimes hang!) - fixed some race condition in testbench - added more elaborate diagnostics to parts of the testbench - bugfixes imported from 4.5.4: * bugfix: potential segfault in stream writer on destruction * bugfix: potential race in object loader (obj.c) during use/release * bugfixes: potential problems in out file zip writer - included some important fixes from 4.4.2: * bugfix: invalid handling of zero-sized messages * bugfix: zero-sized UDP messages are no longer processed * bugfix: random data could be appended to message * bugfix: reverse lookup reduction logic in imudp do DNS queries too often --------------------------------------------------------------------------- Version 5.1.5 [v5-beta] (rgerhards), 2009-09-11 - added new config option $ActionWriteAllMarkMessages this option permites to process mark messages under all circumstances, even if an action was recently called. This can be useful to use mark messages as a kind of heartbeat. - added new config option $InputUnixListenSocketCreatePath to permit the auto-creation of pathes to additional log sockets. This turns out to be useful if they reside on temporary file systems and rsyslogd starts up before the daemons that create these sockets (rsyslogd always creates the socket itself if it does not exist). - added $LogRSyslogStatusMessages configuration directive permitting to turn off rsyslog start/stop/HUP messages. See Debian ticket http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=463793 - bugfix: hostnames with dashes in them were incorrectly treated as malformed, thus causing them to be treated as TAG (this was a regression introduced from the "rfc3164 strict" change in 4.5.0). Testbench has been updated to include a smaple message with a hostname containing a dash. - bugfix: strings improperly reused, resulting in some message properties be populated with strings from previous messages. This was caused by an improper predicate check. - added new config directive $omfileForceChown [import from 4.7.0] --------------------------------------------------------------------------- Version 5.1.4 [DEVEL] (rgerhards), 2009-08-20 - legacy syslog parser changed so that it now accepts date stamps in wrong case. Some devices seem to create them and I do not see any harm in supporting that. - added $InputTCPMaxListeners directive - permits to specify how many TCP servers shall be possible (default is 20). - bugfix: memory leak with some input modules. Those inputs that use parseAndSubmitMsg() leak two small memory blocks with every message. Typically, those process only relatively few messages, so the issue does most probably not have any effect in practice. - bugfix: if tcp listen port could not be created, no error message was emitted - bugfix: discard action did not work (did not discard messages) - bugfix: discard action caused segfault - bugfix: potential segfault in output file writer (omfile) In async write mode, we use modular arithmetic to index the output buffer array. However, the counter variables accidently were signed, thus resulting in negative indizes after integer overflow. That in turn could lead to segfaults, but was depending on the memory layout of the instance in question (which in turn depended on a number of variables, like compile settings but also configuration). The counters are now unsigned (as they always should have been) and so the dangling mis-indexing does no longer happen. This bug potentially affected all installations, even if only some may actually have seen a segfault. --------------------------------------------------------------------------- Version 5.1.3 [DEVEL] (rgerhards), 2009-07-28 - architecture change: queue now always has at least one worker thread if not running in direct mode. Previous versions could run without any active workers. This simplifies the code at a very small expense. See v5 compatibility note document for more in-depth discussion. - enhance: UDP spoofing supported via new output module omudpspoof See the omudpspoof documentation for details and samples - bugfix: message could be truncated after TAG, often when forwarding This was a result of an internal processing error if maximum field sizes had been specified in the property replacer. - bugfix: minor static memory leak while reading configuration did NOT leak based on message volume - internal: added ability to terminate input modules not via pthread_cancel but an alternate approach via pthread_kill. This is somewhat safer as we do not need to think about the cancel-safeness of all libraries we use. However, not all inputs can easily supported, so this now is a feature that can be requested by the input module (the most important ones request it). --------------------------------------------------------------------------- Version 5.1.2 [DEVEL] (rgerhards), 2009-07-08 - bugfix: properties inputname, fromhost, fromhost-ip, msg were lost when working with disk queues - some performance enhancements - bugfix: abort condition when RecvFrom was not set and message reduction was on. Happend e.g. with imuxsock. - added $klogConsoleLogLevel directive which permits to set a new console log level while rsyslog is active - some internal code cleanup --------------------------------------------------------------------------- Version 5.1.1 [DEVEL] (rgerhards), 2009-07-03 - bugfix: huge memory leak in queue engine (made rsyslogd unusable in production). Occured if at least one queue was in direct mode (the default for action queues) - imported many performance optimizations from v4-devel (4.5.0) - bugfix: subtle (and usually irrelevant) issue in timout processing timeout could be one second too early if nanoseconds wrapped - set a more sensible timeout for shutdow, now 1.5 seconds to complete processing (this also removes those cases where the shutdown message was not written because the termination happened before it) --------------------------------------------------------------------------- Version 5.1.0 [DEVEL] (rgerhards), 2009-05-29 *********************************** NOTE ********************************** The v5 versions of rsyslog feature a greatly redesigned queue engine. The major theme for the v5 release is twofold: a) greatly improved performance b) enable audit-grade processing Here, audit-grade processing means that rsyslog, if used together with audit-grade transports and configured correctly, will never lose messages that already have been acknowledged, not even in fatal failure cases like sudden loss of power. Note that large parts of rsyslog's important core components have been restructured to support these design goals. As such, early versions of the engine will probably be less stable than the v3/v4 engine. Also note that the initial versions do not cover all and everything. As usual, the code will evolve toward the final goal as version numbers increase. *********************************** NOTE ********************************** - redesigned queue engine so that it supports ultra-reliable operations This resulted in a rewrite of large parts. The new capability can be used to build audit-grade systems on the basis of rsyslog. - added $MainMsgQueueDequeueBatchSize and $ActionQueueDequeueBatchSize configuration directives - implemented a new transactional output module interface which provides superior performance (for databases potentially far superior performance) - increased ompgsql performance by adapting to new transactional output module interface --------------------------------------------------------------------------- Version 4.8.1 [v4-stable], 2011-09-?? - increased max config file line size to 64k We now also emit an error message if even 64k is not enough (not doing so previously may rightfully be considered as a bug) - bugfix: omprog made rsyslog abort on startup if not binary to execute was configured - bugfix: $ActionExecOnlyOnce interval did not work properly Thanks to Tomas Heinrich for the patch - bugfix: potential abort if ultra-large file io buffers are used and dynafile cache exhausts address space (primarily a problem on 32 bit platforms) - bugfix: potential abort after reading invalid X.509 certificate closes: http://bugzilla.adiscon.com/show_bug.cgi?id=290 Thanks to Tomas Heinrich for the patch. - bugfix: potential fatal abort in omgssapi Thanks to Tomas Heinrich for the patch. - added doc for omprog - FQDN hostname for multihomed host was not always set to the correct name if multiple aliases existed. Thanks to Tomas Heinreich for the patch. - re-licensed larger parts of the codebase under the Apache license 2.0 --------------------------------------------------------------------------- Version 4.8.0 [v4-stable] (rgerhards), 2011-09-07 *************************************************************************** * This is a new stable v4 version. It contains all fixes and enhancements * * made during the 4.7.x phase as well as those listed below. * * Note: major new development to v4 is concluded and will only be done * * for custom projects. * *************************************************************************** There are no changes compared to 4.7.5, just a re-release with the new version number as new v4-stable. The most important new feature is Solaris support. --------------------------------------------------------------------------- Version 4.7.5 [v4-beta], 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: potential misadressing in property replacer - bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) --------------------------------------------------------------------------- Version 4.7.4 [v4-beta] (rgerhards), 2011-07-11 - added support for the ":omusrmsg:" syntax in configuring user messages - added support for the ":omfile:" syntax in configuring user messages - added $LocalHostName config directive - bugfix: PRI was invalid on Solaris for message from local log socket Version 4.7.3 [v4-devel] (rgerhards), 2010-11-25 - added omuxsock, which permits to write message to local Unix sockets this is the counterpart to imuxsock, enabling fast local forwarding - added imptcp, a simplified, Linux-specific and potentielly fast syslog plain tcp input plugin (NOT supporting TLS!) - bugfix: a couple of problems that imfile had on some platforms, namely Ubuntu (not their fault, but occured there) - bugfix: imfile utilizes 32 bit to track offset. Most importantly, this problem can not experienced on Fedora 64 bit OS (which has 64 bit long's!) - added the $InputFilePersistStateInterval config directive to imfile - changed imfile so that the state file is never deleted (makes imfile more robust in regard to fatal failures) --------------------------------------------------------------------------- Version 4.7.2 [v4-devel] (rgerhards), 2010-05-03 - bugfix: problems with atomic operations emulaton replaced atomic operation emulation with new code. The previous code seemed to have some issue and also limited concurrency severely. The whole atomic operation emulation has been rewritten. - added new $Sleep directive to hold processing for a couple of seconds during startup - bugfix: programname filter in ! configuration can not be reset Thanks to Kiss Gabor for the patch. --------------------------------------------------------------------------- Version 4.7.1 [v4-devel] (rgerhards), 2010-04-22 - Solaris support much improved -- was not truely usable in 4.7.0 Solaris is no longer supported in imklog, but rather there is a new plugin imsolaris, which is used to pull local log sources on a Solaris machine. - testbench improvement: Java is no longer needed for testing tool creation --------------------------------------------------------------------------- Version 4.7.0 [v4-devel] (rgerhards), 2010-04-14 - new: support for Solaris added (but not yet the Solaris door API) - added function getenv() to RainerScript - added new config option $InputUnixListenSocketCreatePath to permit the auto-creation of pathes to additional log sockets. This turns out to be useful if they reside on temporary file systems and rsyslogd starts up before the daemons that create these sockets (rsyslogd always creates the socket itself if it does not exist). - added $LogRSyslogStatusMessages configuration directive permitting to turn off rsyslog start/stop/HUP messages. See Debian ticket http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=463793 - added new config directive $omfileForceChown to (try to) fix some broken system configs. See ticket for details: http://bugzilla.adiscon.com/show_bug.cgi?id=150 - added $EscapeControlCharacterTab config directive Thanks to Jonathan Bond-Caron for the patch. - added option to use unlimited-size select() calls Thanks to varmjofekoj for the patch - debugondemand mode caused backgrounding to fail - close to a bug, but I'd consider the ability to background in this mode a new feature... - bugfix (kind of): check if TCP connection is still alive if using TLS Thanks to Jonathan Bond-Caron for the patch. - imported changes from 4.5.7 and below - bugfix: potential segfault when -p command line option was used Thanks for varmojfekoj for pointing me at this bug. - imported changes from 4.5.6 and below --------------------------------------------------------------------------- Version 4.6.8 [v4-stable] (rgerhards), 2011-09-01 - bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 - bugfix: potential misadressing in property replacer - bugfix: memcpy overflow can occur in allowed sender checking if a name is resolved to IPv4-mapped-on-IPv6 address Found by Ismail Dönmez at suse - bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) --------------------------------------------------------------------------- Version 4.6.7 [v4-stable] (rgerhards), 2011-07-11 - added support for the ":omusrmsg:" syntax in configuring user messages - added support for the ":omfile:" syntax for actions --------------------------------------------------------------------------- Version 4.6.6 [v4-stable] (rgerhards), 2011-06-24 - bugfix: memory leak in imtcp & subsystems under some circumstances This leak is tied to error conditions which lead to incorrect cleanup of some data structures. [backport from v6, limited testing under v4] - bugfix: invalid processing in QUEUE_FULL condition If the the multi-submit interface was used and a QUEUE_FULL condition occured, the failed message was properly destructed. However, the rest of the input batch, if it existed, was not processed. So this lead to potential loss of messages and a memory leak. The potential loss of messages was IMHO minor, because they would have been dropped in most cases due to the queue remaining full, but very few lucky ones from the batch may have made it. Anyhow, this has now been changed so that the rest of the batch is properly tried to be enqueued and, if not possible, destructed. - bugfix: invalid storage type for config variables - bugfix: stream driver mode was not correctly set on tcp ouput on big endian systems. thanks varmojfekoj for the patch - bugfix: IPv6-address could not be specified in omrelp this was due to improper parsing of ":" closes: http://bugzilla.adiscon.com/show_bug.cgi?id=250 - bugfix: memory and file descriptor leak in stream processing Leaks could occur under some circumstances if the file stream handler errored out during the open call. Among others, this could cause very big memory leaks if there were a problem with unreadable disk queue files. In regard to the memory leak, this closes: http://bugzilla.adiscon.com/show_bug.cgi?id=256 - bugfix: imfile potentially duplicates lines This can happen when 0 bytes are read from the input file, and some writer appends data to the file BEFORE we check if a rollover happens. The check for rollover uses the inode and size as a criterion. So far, we checked for equality of sizes, which is not given in this scenario, but that does not indicate a rollover. From the source code comments: Note that when we check the size, we MUST NOT check for equality. The reason is that the file may have been written right after we did try to read (so the file size has increased). That is NOT in indicator of a rollover (this is an actual bug scenario we experienced). So we need to check if the new size is smaller than what we already have seen! Also, under some circumstances an invalid truncation was detected. This code has now been removed, a file change (and thus resent) is only detected if the inode number changes. - bugfix: a couple of problems that imfile had on some platforms, namely Ubuntu (not their fault, but occured there) - bugfix: imfile utilizes 32 bit to track offset. Most importantly, this problem can not experienced on Fedora 64 bit OS (which has 64 bit long's!) - bugfix: abort if imfile reads file line of more than 64KiB Thanks to Peter Eisentraut for reporting and analysing this problem. bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=221 - bugfix: omlibdbi did not use password from rsyslog.con closes: http://bugzilla.adiscon.com/show_bug.cgi?id=203 - bugfix: TCP connection invalidly aborted when messages needed to be discarded (due to QUEUE_FULL or similar problem) - bugfix: a slightly more informative error message when a TCP connections is aborted - bugfix: timestamp was incorrectly calculated for timezones with minute offset closes: http://bugzilla.adiscon.com/show_bug.cgi?id=271 - some improvements thanks to clang's static code analyzer o overall cleanup (mostly unnecessary writes and otherwise unused stuff) o bugfix: fixed a very remote problem in msg.c which could occur when running under extremely low memory conditions --------------------------------------------------------------------------- Version 4.6.5 [v4-stable] (rgerhards), 2010-11-24 - bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194 --------------------------------------------------------------------------- Version 4.6.4 [v4-stable] (rgerhards), 2010-08-05 - bugfix: zero-sized (empty) messages were processed by imtcp they are now dropped as they always should have been - bugfix: programname filter in ! configuration can not be reset Thanks to Kiss Gabor for the patch. --------------------------------------------------------------------------- Version 4.6.3 [v4-stable] (rgerhards), 2010-07-07 - improvded testbench - added test with truly random data received via syslog to test robustness - added new configure option that permits to disable and enable an extended testbench - bugfix: segfault on HUP when "HUPIsRestart" was set to "on" thanks varmojfekoj for the patch - bugfix: default for $OMFileFlushOnTXEnd was wrong ("off"). This, in default mode, caused buffered writing to be used, what means that it looked like no output were written or partial lines. Thanks to Michael Biebl for pointing out this bug. - bugfix: testbench failed when not executed in UTC+1 timezone accidently, the time zone information was kept inside some to-be-checked-for responses - temporary bugfix replaced by permanent one for message-induced off-by-one error (potential segfault) (see 4.6.2) The analysis has been completed and a better fix been crafted and integrated. - bugfix: the T/P/E config size specifiers did not work properly under all 32-bit platforms - bugfix: local unix system log socket was deleted even when it was not configured - some doc fixes; incorrect config samples could cause confusion thanks to Anthony Edwards for pointing the problems out --------------------------------------------------------------------------- Version 4.6.2 [v4-stable] (rgerhards), 2010-03-26 - new feature: "." action type added to support writing files to relative pathes (this is primarily meant as a debug aid) - added replacements for atomic instructions on systems that do not support them. [backport of Stefen Sledz' patch for v5) - new feature: $OMFileAsyncWriting directive added it permits to specifiy if asynchronous writing should be done or not - bugfix(temporary): message-induced off-by-one error (potential segfault) Some types of malformed messages could trigger an off-by-one error (for example, \0 or \n as the last character, and generally control character escaption is questionable). This is due to not strictly following a the \0 or string counted string paradigm (during the last optimization on the cstring class). As a temporary fix, we have introduced a proper recalculation of the size. However, a final patch is expected in the future. See bug tracker for further details and when the final patch will be available: http://bugzilla.adiscon.com/show_bug.cgi?id=184 Note that the current patch is considered sufficient to solve the situation, but it requires a bit more runtime than desirable. - bugfix: potential segfault in dynafile cache This bug was triggered by an open failure. The the cache was full and a new entry needed to be placed inside it, a victim for eviction was selected. That victim was freed, then the open of the new file tried. If the open failed, the victim entry was still freed, and the function exited. However, on next invocation and cache search, the victim entry was used as if it were populated, most probably resulting in a segfault. - bugfix: race condition during directory creation If multiple files try to create a directory at (almost) the same time, some of them may fail. This is a data race and also exists with other processes that may create the same directory. We do now check for this condition and gracefully handle it. - bugfix: potential re-use of free()ed file stream object in omfile when dynaCache is enabled, the cache is full, a new entry needs to be allocated, thus the LRU discarded, then a new entry is opend and that fails. In that case, it looks like the discarded stream may be reused improperly (based on code analysis, test case and confirmation pending) - added new property replacer option "date-rfc3164-buggyday" primarily to ease migration from syslog-ng. See property replacer doc for details. [backport from 5.5.3 because urgently needed by some] - improved testbench - bugfix: invalid buffer write in (file) stream class currently being accessed buffer could be overwritten with new data. While this probably did not cause access violations, it could case loss and/or duplication of some data (definitely a race with no deterministic outcome) - bugfix: potential hang condition during filestream close predicate was not properly checked when waiting for the background file writer - bugfix: improper synchronization when "$OMFileFlushOnTXEnd on" was used Internal data structures were not properly protected due to missing mutex calls. - bugfix: potential data loss during file stream shutdown - bugfix: potential problems during file stream shutdown The shutdown/close sequence was not clean, what potentially (but unlikely) could lead to some issues. We have not been able to describe any fatal cases, but there was some bug potential. Sequence has now been straighted out. - bugfix: potential problem (loop, abort) when file write error occured When a write error occured in stream.c, variable iWritten had the error code but this was handled as if it were the actual number of bytes written. That was used in pointer arithmetic later on, and thus could lead to all sorts of problems. However, this could only happen if the error was EINTR or the file in question was a tty. All other cases were handled properly. Now, iWritten is reset to zero in such cases, resulting in proper retries. - bugfix: $omfileFlushOnTXEnd was turned on when set to off and vice versa due to an invalid check - bugfix: recent patch to fix small memory leak could cause invalid free. This could only happen during config file parsing. - bugfix(minor): handling of extremely large strings in dbgprintf() fixed Previously, it could lead to garbagge output and, in extreme cases, also to segfaults. Note: this was a problem only when debug output was actually enabled, so it caused no problem in production use. - bugfix(minor): BSD_SO_COMPAT query function had some global vars not properly initialized. However, in practice the loader initializes them with zero, the desired value, so there were no actual issue in almost all cases. --------------------------------------------------------------------------- Version 4.6.1 [v4-stable] (rgerhards), 2010-03-04 - re-enabled old pipe output (using new module ompipe, built-in) after some problems with pipes (and especially in regard to xconsole) were discovered. Thanks to Michael Biebl for reporting the issues. - bugfix: potential problems with large file support could cause segfault ... and other weird problems. This seemed to affect 32bit-platforms only, but I can not totally outrule there were issues on other platforms as well. The previous code could cause system data types to be defined inconsistently, and that could lead to various troubles. Special thanks go to the Mandriva team for identifying an initial problem, help discussing it and ultimately a fix they contributed. - bugfix: fixed problem that caused compilation on FreeBSD 9.0 to fail. bugtracker: http://bugzilla.adiscon.com/show_bug.cgi?id=181 Thanks to Christiano for reporting. - bugfix: potential segfault in omfile when a dynafile open failed In that case, a partial cache entry was written, and some internal pointers (iCurrElt) not correctly updated. In the next iteration, that could lead to a segfault, especially if iCurrElt then points to the then-partial record. Not very likely, but could happen in practice. - bugfix (theoretical): potential segfault in omfile under low memory condition. This is only a theoretical bug, because it would only happen when strdup() fails to allocate memory - which is highly unlikely and will probably lead to all other sorts of errors. - bugfix: comment char ('#') in literal terminated script parsing and thus could not be used. but tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=119 [merged in from v3.22.2] --------------------------------------------------------------------------- Version 4.6.0 [v4-stable] (rgerhards), 2010-02-24 *************************************************************************** * This is a new stable v4 version. It contains all fixes and enhancements * * made during the 4.5.x phase as well as those listed below. * * Note: this version is scheduled to conclude the v4 development process. * * Do not expect any more new developments in v4. The focus is now * * on v5 (what also means we have a single devel branch again). * * ("development" means new feature development, bug fixes are of * * course provided for v4-stable) * *************************************************************************** - improved testbench to contain samples for totally malformed messages which miss parts of the message content - bugfix: some malformed messages could lead to a missing LF inside files or some other missing parts of the template content. - bugfix: if a message ended immediately with a hostname, the hostname was mistakenly interpreted as TAG, and localhost be used as hostname - bugfix: message without MSG part could case a segfault [backported from v5 commit 98d1ed504ec001728955a5bcd7916f64cd85f39f] This actually was a "recent" regression, but I did not realize that it was introduced by the performance optimization in v4-devel. Shame on me for having two devel versions at the same time... --------------------------------------------------------------------------- Version 4.5.8 [v4-beta] (rgerhards), 2010-02-10 - enhanced doc for using PostgreSQL Thanks to Marc Schiffbauer for the new/updated doc - bugfix: property replacer returned invalid parameters under some (unusual) conditions. In extreme cases, this could lead to garbled logs and/or a system failure. - bugfix: invalid length returned (often) when using regular expressions inside the property replacer - bugfix: submatch regex in property replacer did not honor "return 0 on no match" config case - bugfix: imuxsock incorrectly stated inputname "imudp" Thanks to Ryan Lynch for reporting this. - (slightly) enhanced support for FreeBSD by setting _PATH_MODDIR to the correct value on FreeBSD. Thanks to Cristiano for the patch. - bugfix: -d did not enable display of debug messages regression from introduction of "debug on demand" mode Thanks to Michael Biebl for reporting this bug - bugfix: blanks inside file names did not terminate file name parsing. This could reslult in the whole rest of a line (including comments) to be treated as file name in "write to file" actions. Thanks to Jack for reporting this issue. - bugfix: rsyslog hang when writing to a named pipe which nobody was reading. Thanks to Michael Biebl for reporting this bug. Bugzilla entry: http://bugzilla.adiscon.com/show_bug.cgi?id=169 - bugfix: potential segfaults during queue shutdown (bugs require certain non-standard settings to appear) Thanks to varmojfekoj for the patch --------------------------------------------------------------------------- Version 4.5.7 [v4-beta] (rgerhards), 2009-11-18 - added a so-called "On Demand Debug" mode, in which debug output can be generated only after the process has started, but not right from the beginning. This is assumed to be useful for hard-to-find bugs. Also improved the doc on the debug system. - bugfix (kind of): check if TCP connection is still alive if using TLS Thanks to Jonathan Bond-Caron for the patch. - bugfix: hostname accidently set to IP address for some message sources, for example imudp. Thanks to Anton for reporting this bug. - bugfix [imported from 4.4.3]: $ActionExecOnlyOnceEveryInterval did not work. --------------------------------------------------------------------------- Version 4.5.6 [v4-beta] (rgerhards), 2009-11-05 - bugfix: named pipes did no longer work (they always got an open error) this was a regression from the omfile rewrite in 4.5.0 - bugfix(minor): diag function returned wrong queue memeber count for the main queue if an active DA queue existed. This had no relevance to real deployments (assuming they are not running the debug/diagnostic module...), but sometimes caused grief and false alerts in the testbench. - included some important fixes from v4-stable: * bugfix: invalid handling of zero-sized messages * bugfix: zero-sized UDP messages are no longer processed * bugfix: random data could be appended to message * bugfix: reverse lookup reduction logic in imudp do DNS queries too often - bugfix(testbench): testcase did not properly wait for rsyslod shutdown thus some unpredictable behavior and a false negative test result could occur. [BACKPORTED from v5] - bugfix(testbench): sequence check was not always performed correctly, that could result in tests reporting success when they actually failed --------------------------------------------------------------------------- Version 4.5.5 [v4-beta] (rgerhards), 2009-10-21 - added $InputTCPServerNotifyOnConnectionClose config directive see doc for details - bugfix: debug string larger than 1K were improperly displayed. Max size is now 32K - bugfix: invalid storage class selected for some size config parameters. This resulted in wrong values. The most prominent victim was the directory creation mode, which was set to zero in some cases. For details, see related blog post: http://blog.gerhards.net/2009/10/another-note-on-hard-to-find-bugs.html --------------------------------------------------------------------------- Version 4.5.4 [v4-beta] (rgerhards), 2009-09-29 - bugfix: potential segfault in stream writer on destruction Most severely affected omfile. The problem was that some buffers were freed before the asynchronous writer thread was shut down. So the writer thread accessed invalid data, which may even already be overwritten. Symptoms (with omfile) were segfaults, grabled data and files with random names placed around the file system (most prominently into the root directory). Special thanks to Aaron for helping to track this down. - bugfix: potential race in object loader (obj.c) during use/release of object interface - bugfixes: potential problems in out file zip writer. Problems could lead to abort and/or memory leak. The module is now hardened in a very conservative way, which is sub-optimal from a performance point of view. This should be improved if it has proven reliable in practice. --------------------------------------------------------------------------- Version 4.5.3 [v4-beta] (rgerhards), 2009-09-17 - bugfix: repeated messages were incorrectly processed this could lead to loss of the repeated message content. As a side- effect, it could probably also be possible that some segfault occurs (quite unlikely). The root cause was that some counters introduced during the malloc optimizations were not properly duplicated in MsgDup(). Note that repeated message processing is not enabled by default. - bugfix: message sanitation had some issues: - control character DEL was not properly escaped - NUL and LF characters were not properly stripped if no control character replacement was to be done - NUL characters in the message body were silently dropped (this was a regeression introduced by some of the recent optimizations) - bugfix: strings improperly reused, resulting in some message properties be populated with strings from previous messages. This was caused by an improper predicate check. [backported from v5] - fixed some minor portability issues - bugfix: reverse lookup reduction logic in imudp do DNS queries too often [imported from 4.4.2] --------------------------------------------------------------------------- Version 4.5.2 [v4-beta] (rgerhards), 2009-08-21 - legacy syslog parser changed so that it now accepts date stamps in wrong case. Some devices seem to create them and I do not see any harm in supporting that. - added $InputTCPMaxListeners directive - permits to specify how many TCP servers shall be possible (default is 20). - bugfix: memory leak with some input modules. Those inputs that use parseAndSubmitMsg() leak two small memory blocks with every message. Typically, those process only relatively few messages, so the issue does most probably not have any effect in practice. - bugfix: if tcp listen port could not be created, no error message was emitted - bugfix: potential segfault in output file writer (omfile) In async write mode, we use modular arithmetic to index the output buffer array. However, the counter variables accidently were signed, thus resulting in negative indizes after integer overflow. That in turn could lead to segfaults, but was depending on the memory layout of the instance in question (which in turn depended on a number of variables, like compile settings but also configuration). The counters are now unsigned (as they always should have been) and so the dangling mis-indexing does no longer happen. This bug potentially affected all installations, even if only some may actually have seen a segfault. - bugfix: hostnames with dashes in them were incorrectly treated as malformed, thus causing them to be treated as TAG (this was a regression introduced from the "rfc3164 strict" change in 4.5.0). --------------------------------------------------------------------------- Version 4.5.1 [DEVEL] (rgerhards), 2009-07-15 - CONFIG CHANGE: $HUPisRestart default is now "off". We are doing this to support removal of restart-type HUP in v5. - bugfix: fromhost-ip was sometimes truncated - bugfix: potential segfault when zip-compressed syslog records were received (double free) - bugfix: properties inputname, fromhost, fromhost-ip, msg were lost when working with disk queues - performance enhancement: much faster, up to twice as fast (depending on configuration) - bugfix: abort condition when RecvFrom was not set and message reduction was on. Happend e.g. with imuxsock. - added $klogConsoleLogLevel directive which permits to set a new console log level while rsyslog is active - bugfix: message could be truncated after TAG, often when forwarding This was a result of an internal processing error if maximum field sizes had been specified in the property replacer. - added ability for the TCP output action to "rebind" its send socket after sending n messages (actually, it re-opens the connection, the name is used because this is a concept very similiar to $ActionUDPRebindInterval). New config directive $ActionSendTCPRebindInterval added for the purpose. By default, rebinding is disabled. This is considered useful for load balancers. - testbench improvements --------------------------------------------------------------------------- Version 4.5.0 [DEVEL] (rgerhards), 2009-07-02 - activation order of inputs changed, they are now activated only after privileges are dropped. Thanks to Michael Terry for the patch. - greatly improved performance - greatly reduced memory requirements of msg object to around half of the previous demand. This means that more messages can be stored in core! Due to fewer cache misses, this also means some performance improvement. - improved config error messages: now contain a copy of the config line that (most likely) caused the error - reduced max value for $DynaFileCacheSize to 1,000 (the former maximum of 10,000 really made no sense, even 1,000 is very high, but we like to keep the user in control ;)). - added capability to fsync() queue disk files for enhanced reliability (also add's speed, because you do no longer need to run the whole file system in sync mode) - more strict parsing of the hostname in rfc3164 mode, hopefully removes false positives (but may cause some trouble with hostname parsing). For details, see this bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=126 - omfile rewrite to natively support zip files (includes large extension of the stream class) - added configuration commands (see doc for explanations) * $OMFileZipLevel * $OMFileIOBufferSize * $OMFileFlushOnTXEnd * $MainMsgQueueSyncQueueFiles * $ActionQueueSyncQueueFiles - done some memory accesses explicitely atomic - bugfix: subtle (and usually irrelevant) issue in timout processing timeout could be one second too early if nanoseconds wrapped - set a more sensible timeout for shutdow, now 1.5 seconds to complete processing (this also removes those cases where the shutdown message was not written because the termination happened before it) - internal bugfix: object pointer was only reset to NULL when an object was actually destructed. This most likely had no effect to existing code, but it may also have caused trouble in remote cases. Similarly, the fix may also cause trouble... - bugfix: missing initialization during timestamp creation This could lead to timestamps written in the wrong format, but not to an abort --------------------------------------------------------------------------- Version 4.4.3 [v4-stable] (rgerhards), 2009-10-?? - bugfix: several smaller bugs resolved after flexelint review Thanks to varmojfekoj for the patch. - bugfix: $ActionExecOnlyOnceEveryInterval did not work. This was a regression from the time() optimizations done in v4. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=143 Thanks to Klaus Tachtler for reporting this bug. - bugfix: potential segfault on queue shutdown Thanks to varmojfekoj for the patch. - bugfix: potential hang condition on queue shutdown [imported from v3-stable] - bugfix: segfault on startup when -q or -Q option was given [imported from v3-stable] --------------------------------------------------------------------------- Version 4.4.2 [v4-stable] (rgerhards), 2009-10-09 - bugfix: invalid handling of zero-sized messages, could lead to mis- addressing and potential memory corruption/segfault - bugfix: zero-sized UDP messages are no longer processed until now, they were forwarded to processing, but this makes no sense Also, it looks like the system seems to provide a zero return code on a UDP recvfrom() from time to time for some internal reasons. These "receives" are now silently ignored. - bugfix: random data could be appended to message, possibly causing segfaults - bugfix: reverse lookup reduction logic in imudp do DNS queries too often A comparison was done between the current and the former source address. However, this was done on the full sockaddr_storage structure and not on the host address only. This has now been changed for IPv4 and IPv6. The end result of this bug could be a higher UDP message loss rate than necessary (note that UDP message loss can not totally be avoided due to the UDP spec) --------------------------------------------------------------------------- Version 4.4.1 [v4-stable] (rgerhards), 2009-09-02 - features requiring Java are automatically disabled if Java is not present (thanks to Michael Biebl for his help!) - bugfix: invalid double-quoted PRI, among others in outgoing messages This causes grief with all receivers. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=147 - bugfix: Java testing tools were required, even if testbench was disabled This resulted in build errors if no Java was present on the build system, even though none of the selected option actually required Java. (I forgot to backport a similar fix to newer releases). - bugfix (backport): omfwd segfault Note that the orginal (higher version) patch states this happens only when debugging mode is turned on. That statement is wrong: if debug mode is turned off, the message is not being emitted, but the division by zero in the actual parameters still happens. --------------------------------------------------------------------------- Version 4.4.0 [v4-stable] (rgerhards), 2009-08-21 - bugfix: stderr/stdout were not closed to be able to emit error messages, but this caused ssh sessions to hang. Now we close them after the initial initialization. See forum thread: http://kb.monitorware.com/controlling-terminal-issues-t9875.html - bugfix: sending syslog messages with zip compression did not work --------------------------------------------------------------------------- Version 4.3.2 [v4-beta] (rgerhards), 2009-06-24 - removed long-obsoleted property UxTradMsg - added a generic network stream server (in addition to rather specific syslog tcp server) - added ability for the UDP output action to rebind its send socket after sending n messages. New config directive $ActionSendUDPRebindInterval added for the purpose. By default, rebinding is disabled. This is considered useful for load balancers. - bugfix: imdiag/imtcp had a race condition - improved testbench (now much better code design and reuse) - added config switch --enable-testbench=no to turn off testbench --------------------------------------------------------------------------- Version 4.3.1 [DEVEL] (rgerhards), 2009-05-25 - added capability to run multiple tcp listeners (on different ports) - performance enhancement: imtcp calls parser no longer on input thread but rather inside on of the potentially many main msg queue worker threads (an enhancement scheduled for all input plugins where this is possible) - added $GenerateConfigGraph configuration command which can be used to generate nice-looking (and very informative) rsyslog configuration graphs. - added $ActionName configuration directive (currently only used for graph generation, but may find other uses) - improved doc * added (hopefully) easier to grasp queue explanation - improved testbench * added tests for queue disk-only mode (checks disk queue logic) - bugfix: light and full delay watermarks had invalid values, badly affecting performance for delayable inputs - build system improvements - thanks to Michael Biebl - added new testing module imdiag, which enables to talk to the rsyslog core at runtime. The current implementation is only a beginning, but can be expanded over time --------------------------------------------------------------------------- Version 4.3.0 [DEVEL] (rgerhards), 2009-04-17 - new feature: new output plugin omprog, which permits to start program and feed it (via its stdin) with syslog messages. If the program terminates, it is restarted. - improved internal handling of RainerScript functions, building the necessary plumbing to support more functions with decent runtime performance. This is also necessary towards the long-term goal of loadable library modules. - added new RainerScript function "tolower" - improved testbench * added tests for tcp-based reception * added tcp-load test (1000 connections, 20,000 messages) - added $MaxOpenFiles configuration directive - bugfix: solved potential memory leak in msg processing, could manifest itself in imtcp - bugfix: ompgsql did not detect problems in sql command execution this could cause loss of messages. The handling was correct if the connection broke, but not if there was a problem with statement execution. The most probable case for such a case would be invalid sql inside the template, and this is now much easier to diagnose. --------------------------------------------------------------------------- Version 4.2.0 [v4-stable] (rgerhards), 2009-06-23 - bugfix: light and full delay watermarks had invalid values, badly affecting performance for delayable inputs - imported all patches from 3.22.1 as of today (see below) - bugfix: compile problems in im3195 --------------------------------------------------------------------------- Version 4.1.7 [BETA] (rgerhards), 2009-04-22 - bugfix: $InputTCPMaxSessions config directive was accepted, but not honored. This resulted in a fixed upper limit of 200 connections. - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html - bugfix: ompgsql did not detect problems in sql command execution this could cause loss of messages. The handling was correct if the connection broke, but not if there was a problem with statement execution. The most probable case for such a case would be invalid sql inside the template, and this is now much easier to diagnose. --------------------------------------------------------------------------- Version 4.1.6 [DEVEL] (rgerhards), 2009-04-07 - added new "csv" property replacer options to enable simple creation of CSV-formatted outputs (format from RFC4180 is used) - implemented function support in RainerScript. That means the engine parses and compile functions, as well as executes a few build-in ones. Dynamic loading and registration of functions is not yet supported - but we now have a good foundation to do that later on. - implemented the strlen() RainerScript function - added a template output module - added -T rsyslogd command line option, enables to specify a directory where to chroot() into on startup. This is NOT a security feature but introduced to support testing. Thus, -T does not make sure chroot() is used in a secure way. (may be removed later) - added omstdout module for testing purposes. Spits out all messages to stdout - no config option, no other features - added a parser testing suite (still needs to be extended, but a good start) - modified $ModLoad statement so that for modules whom's name starts with a dot, no path is prepended (this enables relative-pathes and should not break any valid current config) - fixed a bug that caused action retries not to work correctly situation was only cleared by a restart - bugfix: closed dynafile was potentially never written until another dynafile name was generated - potential loss of messages - improved omfile so that it properly suspends itself if there is an i/o or file name generation error. This enables it to be used with the full high availability features of rsyslog's engine - bugfix: fixed some segaults on Solaris, where vsprintf() does not check for NULL pointers - improved performance of regexp-based filters Thanks to Arnaud Cornet for providing the idea and initial patch. - added a new way how output plugins may be passed parameters. This is more effcient for some outputs. They new can receive fields not only as a single string but rather in an array where each string is seperated. - added (some) developer documentation for output plugin interface - bugfix: potential abort with DA queue after high watermark is reached There exists a race condition that can lead to a segfault. Thanks go to vbernetr, who performed the analysis and provided patch, which I only tweaked a very little bit. - bugfix: imtcp did incorrectly parse hostname/tag Thanks to Luis Fernando Muñoz Mejías for the patch. --------------------------------------------------------------------------- Version 4.1.5 [DEVEL] (rgerhards), 2009-03-11 - bugfix: parser did not correctly parse fields in UDP-received messages - added ERE support in filter conditions new comparison operation "ereregex" - added new config directive $RepeatedMsgContainsOriginalMsg so that the "last message repeated n times" messages, if generated, may have an alternate format that contains the message that is being repeated --------------------------------------------------------------------------- Version 4.1.4 [DEVEL] (rgerhards), 2009-01-29 - bugfix: inconsistent use of mutex/atomic operations could cause segfault details are too many, for full analysis see blog post at: http://blog.gerhards.net/2009/01/rsyslog-data-race-analysis.html - bugfix: unitialized mutex was used in msg.c:getPRI This was subtle, because getPRI is called as part of the debugging code (always executed) in syslogd.c:logmsg. - bufgix: $PreserveFQDN was not properly handled for locally emitted messages --------------------------------------------------------------------------- Version 4.1.3 [DEVEL] (rgerhards), 2008-12-17 - added $InputTCPServerAddtlFrameDelimiter config directive, which enables to specify an additional, non-standard message delimiter for processing plain tcp syslog. This is primarily a fix for the invalid framing used in Juniper's NetScreen products. Credit to forum user Arv for suggesting this solution. - added $InputTCPServerInputName property, which enables a name to be specified that will be available during message processing in the inputname property. This is considered useful for logic that treats messages differently depending on which input received them. - added $PreserveFQDN config file directive Enables to use FQDNs in sender names where the legacy default would have stripped the domain part. Thanks to BlinkMind, Inc. http://www.blinkmind.com for sponsoring this development. - bugfix: imudp went into an endless loop under some circumstances (but could also leave it under some other circumstances...) Thanks to David Lang and speedfox for reporting this issue. --------------------------------------------------------------------------- Version 4.1.2 [DEVEL] (rgerhards), 2008-12-04 - bugfix: code did not compile without zlib - security bugfix: $AllowedSender was not honored, all senders were permitted instead (see http://www.rsyslog.com/Article322.phtml) - security fix: imudp emitted a message when a non-permitted sender tried to send a message to it. This behaviour is operator-configurable. If enabled, a message was emitted each time. That way an attacker could effectively fill the disk via this facility. The message is now emitted only once in a minute (this currently is a hard-coded limit, if someone comes up with a good reason to make it configurable, we will probably do that). - doc bugfix: typo in v3 compatibility document directive syntax thanks to Andrej for reporting - imported other changes from 3.21.8 and 3.20.1 (see there) --------------------------------------------------------------------------- Version 4.1.1 [DEVEL] (rgerhards), 2008-11-26 - added $PrivDropToGroup, $PrivDropToUser, $PrivDropToGroupID, $PrivDropToUserID config directives to enable dropping privileges. This is an effort to provide a security enhancement. For the limits of this approach, see http://wiki.rsyslog.com/index.php/Security - re-enabled imklog to compile on FreeBSD (brought in from beta) --------------------------------------------------------------------------- Version 4.1.0 [DEVEL] (rgerhards), 2008-11-18 ********************************* WARNING ********************************* This version has a slightly different on-disk format for message entries. As a consequence, old queue files being read by this version may have an invalid output timestamp, which could result to some malfunction inside the output driver. It is recommended to drain queues with the previous version before switching to this one. ********************************* WARNING ********************************* - greatly enhanced performance when compared to v3. - added configuration directive "HUPisRestart" which enables to configure HUP to be either a full restart or "just" a leightweight way to close open files. - enhanced legacy syslog parser to detect year if part of the timestamp the format is based on what Cisco devices seem to emit. - added a setting "$OptimizeForUniprocessor" to enable users to turn off pthread_yield calls which are counter-productive on multiprocessor machines (but have been shown to be useful on uniprocessors) - reordered imudp processing. Message parsing is now done as part of main message queue worker processing (was part of the input thread) This should also improve performance, as potentially more work is done in parallel. - bugfix: compressed syslog messages could be slightly mis-uncompressed if the last byte of the compressed record was a NUL - added $UDPServerTimeRequery option which enables to work with less acurate timestamps in favor of performance. This enables querying of the time only every n-th time if imudp is running in the tight receive loop (aka receiving messsages at a high rate) - doc bugfix: queue doc had wrong parameter name for setting controlling worker thread shutdown period - restructured rsyslog.conf documentation - bugfix: memory leak in ompgsql Thanks to Ken for providing the patch --------------------------------------------------------------------------- Version 3.22.4 [v3-stable] (rgerhards), 2010-??-?? - bugfix: action resume interval incorrectly handled, thus took longer to resume - bugfix: cosmetic: proper constant used instead of number in open call - bugfix: timestamp was incorrectly calculated for timezones with minute offset closes: http://bugzilla.adiscon.com/show_bug.cgi?id=271 - improved some code based on clang static analyzer results - bugfix: potential misadressing in property replacer --------------------------------------------------------------------------- Version 3.22.3 [v3-stable] (rgerhards), 2010-11-24 - bugfix(important): problem in TLS handling could cause rsyslog to loop in a tight loop, effectively disabling functionality and bearing the risk of unresponsiveness of the whole system. Bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=194 --------------------------------------------------------------------------- Version 3.22.2 [v3-stable] (rgerhards), 2010-08-05 - bugfix: comment char ('#') in literal terminated script parsing and thus could not be used. but tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=119 - enhance: imrelp now also provides remote peer's IP address [if librelp != 1.0.0 is used] - bugfix: sending syslog messages with zip compression did not work - bugfix: potential hang condition on queue shutdown - bugfix: segfault on startup when -q or -Q option was given bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=157 Thanks to Jonas Nogueira for reporting this bug. - clarified use of $ActionsSendStreamDriver[AuthMode/PermittedPeers] in doc set (require TLS drivers) - bugfix: $CreateDirs variable not properly initialized, default thus was random (but most often "on") - bugfix: potential segfault when -p command line option was used thanks to varmojfekoj for pointing me at this bug - bugfix: programname filter in ! configuration can not be reset Thanks to Kiss Gabor for the patch. --------------------------------------------------------------------------- Version 3.22.1 [v3-stable] (rgerhards), 2009-07-02 - bugfix: invalid error message issued if $inlcudeConfig was on an empty set of files (e.g. *.conf, where none such files existed) thanks to Michael Biebl for reporting this bug - bugfix: when run in foreground (but not in debug mode), a debug message ("DoDie called") was emitted at shutdown. Removed. thanks to Michael Biebl for reporting this bug - bugfix: some garbagge was emitted to stderr on shutdown. This garbage consisted of file names, which were written during startup (key point: not a pointer error) thanks to Michael Biebl for reporting this bug - bugfix: startup and shutdown message were emitted to stdout thanks to Michael Biebl for reporting this bug - bugfix: error messages were not emitted to stderr in forked mode (stderr and stdo are now kept open across forks) - bugfix: internal messages were emitted to whatever file had fd2 when rsyslogd ran in forked mode (as usual!) Thanks to varmojfekoj for the patch - small enhancement: config validation run now exits with code 1 if an error is detected. This change is considered important but small enough to apply it directly to the stable version. [But it is a border case, the change requires more code than I had hoped. Thus I have NOT tried to actually catch all cases, this is left for the current devel releases, if necessary] - bugfix: light and full delay watermarks had invalid values, badly affecting performance for delayable inputs - bugfix: potential segfault issue when multiple $UDPServerRun directives are specified. Thanks to Michael Biebl for helping to debug this one. - relaxed GnuTLS version requirement to 1.4.0 after confirmation from the field that this version is sufficient - bugfix: parser did not properly handle empty structured data - bugfix: invalid mutex release in msg.c (detected under thread debugger, seems not to have any impact on actual deployments) --------------------------------------------------------------------------- Version 3.22.0 [v3-stable] (rgerhards), 2009-04-21 This is the first stable release that includes the full functionality of the 3.21.x version tree. - bugfix: $InputTCPMaxSessions config directive was accepted, but not honored. This resulted in a fixed upper limit of 200 connections. - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html - bugfix: ompgsql did not detect problems in sql command execution this could cause loss of messages. The handling was correct if the connection broke, but not if there was a problem with statement execution. The most probable case for such a case would be invalid sql inside the template, and this is now much easier to diagnose. --------------------------------------------------------------------------- Version 3.21.11 [BETA] (rgerhards), 2009-04-03 - build system improvements contributed by Michael Biebl - thx! - all patches from 3.20.5 incorporated (see it's ChangeLog entry) --------------------------------------------------------------------------- Version 3.21.10 [BETA] (rgerhards), 2009-02-02 - bugfix: inconsistent use of mutex/atomic operations could cause segfault details are too many, for full analysis see blog post at: http://blog.gerhards.net/2009/01/rsyslog-data-race-analysis.html - the string "Do Die" was accidently emited upon exit in non-debug mode This has now been corrected. Thanks to varmojfekoj for the patch. - some legacy options were not correctly processed. Thanks to varmojfekoj for the patch. - doc bugfix: v3-compatiblity document had typo in config directive thanks to Andrej for reporting this --------------------------------------------------------------------------- Version 3.21.9 [BETA] (rgerhards), 2008-12-04 - re-release of 3.21.8 with an additional fix, that could also lead to DoS; 3.21.8 has been removed from the official download archives - security fix: imudp emitted a message when a non-permitted sender tried to send a message to it. This behaviour is operator-configurable. If enabled, a message was emitted each time. That way an attacker could effectively fill the disk via this facility. The message is now emitted only once in a minute (this currently is a hard-coded limit, if someone comes up with a good reason to make it configurable, we will probably do that). --------------------------------------------------------------------------- Version 3.21.8 [BETA] (rgerhards), 2008-12-04 - bugfix: imklog did not compile on FreeBSD - security bugfix: $AllowedSender was not honored, all senders were permitted instead (see http://www.rsyslog.com/Article322.phtml) - merged in all other changes from 3.20.1 (see there) --------------------------------------------------------------------------- Version 3.21.7 [BETA] (rgerhards), 2008-11-11 - this is the new beta branch, based on the former 3.21.6 devel - new functionality: ZERO property replacer nomatch option (from v3-stable) --------------------------------------------------------------------------- Version 3.21.6 [DEVEL] (rgerhards), 2008-10-22 - consolidated time calls during msg object creation, improves performance and consistency - bugfix: solved a segfault condition - bugfix: subsecond time properties generated by imfile, imklog and internal messages could be slightly inconsistent - bugfix: (potentially big) memory leak on HUP if queues could not be drained before timeout - thanks to David Lang for pointing this out - added capability to support multiple module search pathes. Thank to Marius Tomaschewski for providing the patch. - bugfix: im3195 did no longer compile - improved "make distcheck" by ensuring everything relevant is recompiled --------------------------------------------------------------------------- Version 3.21.5 [DEVEL] (rgerhards), 2008-09-30 - performance optimization: unnecessary time() calls during message parsing removed - thanks to David Lang for his excellent performance analysis - added new capability to property replacer: multiple immediately successive field delimiters are treated as a single one. Thanks to Zhuang Yuyao for the patch. - added message property "inputname", which contains the name of the input (module) that generated it. Presence is depending on suport in each input module (else it is blank). - added system property "$myhostname", which contains the name of the local host as it knows itself. - imported a number of fixes and enhancements from the stable and devel branches, including a fix to a potential segfault on HUP when using UDP listners - re-enabled gcc builtin atomic operations and added a proper ./configure check - bugfix: potential race condition when adding messages to queue There was a wrong order of mutex lock operations. It is hard to believe that really caused problems, but in theory it could and with threading we often see that theory becomes practice if something is only used long enough on a fast enough machine with enough CPUs ;) - cleaned up internal debug system code and made it behave better in regard to multi-threading --------------------------------------------------------------------------- Version 3.21.4 [DEVEL] (rgerhards), 2008-09-04 - removed compile time fixed message size limit (was 2K), limit can now be set via $MaxMessageSize global config directive (finally gotten rid of MAXLINE ;)) - enhanced doc for $ActionExecOnlyEveryNthTimeTimeout - integrated a number of patches from 3.18.4, namely - bugfix: order-of magnitude issue with base-10 size definitions in config file parser. Could lead to invalid sizes, constraints etc for e.g. queue files and any other object whose size was specified in base-10 entities. Did not apply to binary entities. Thanks to RB for finding this bug and providing a patch. - bugfix: action was not called when system time was set backwards (until the previous time was reached again). There are still some side-effects when time is rolled back (A time rollback is really a bad thing to do, ideally the OS should issue pseudo time (like NetWare did) when the user tries to roll back time). Thanks to varmojfekoj for this patch. - doc bugfix: rsyslog.conf man page improved and minor nit fixed thanks to Lukas Kuklinek for the patch. --------------------------------------------------------------------------- Version 3.21.3 [DEVEL] (rgerhards), 2008-08-13 - added ability to specify flow control mode for imuxsock - added ability to execute actions only after the n-th call of the action This also lead to the addition of two new config directives: $ActionExecOnlyEveryNthTime and $ActionExecOnlyEveryNthTimeTimeout This feature is useful, for example, for alerting: it permits you to send an alert only after at least n occurences of a specific message have been seen by rsyslogd. This protectes against false positives due to waiting for additional confirmation. - bugfix: IPv6 addresses could not be specified in forwarding actions New syntax @[addr]:port introduced to enable that. Root problem was IPv6 addresses contain colons. - somewhat enhanced debugging messages - imported from 3.18.3: - enhanced ommysql to support custom port to connect to server Port can be set via new $ActionOmmysqlServerPort config directive Note: this was a very minor change and thus deemed appropriate to be done in the stable release. - bugfix: misspelled config directive, previously was $MainMsgQueueWorkeTimeoutrThreadShutdown, is now $MainMsgQueueWorkerTimeoutThreadShutdown. Note that the misspelled directive is not preserved - if the misspelled directive was used (which I consider highly unlikely), the config file must be changed. Thanks to lperr for reporting the bug. --------------------------------------------------------------------------- Version 3.21.2 [DEVEL] (rgerhards), 2008-08-04 - added $InputUnixListenSocketHostName config directive, which permits to override the hostname being used on a local unix socket. This is useful for differentiating "hosts" running in several jails. Feature was suggested by David Darville, thanks for the suggestion. - enhanced ommail to support multiple email recipients. This is done by specifying $ActionMailTo multiple times. Note that this introduces a small incompatibility to previous config file syntax: the recipient list is now reset for each action (we honestly believe that will not cause any problem - apologies if it does). - enhanced troubleshooting documentation --------------------------------------------------------------------------- Version 3.21.1 [DEVEL] (rgerhards), 2008-07-30 - bugfix: no error was reported if the target of a $IncludeConfig could not be accessed. - added testbed for common config errors - added doc for -u option to rsyslogd man page - enhanced config file checking - no active actions are detected - added -N rsyslogd command line option for a config validation run (which does not execute actual syslogd code and does not interfere with a running instance) - somewhat improved emergency configuration. It is now also selected if the config contains no active actions - rsyslogd error messages are now reported to stderr by default. can be turned off by the new "$ErrorMessagesToStderr off" directive Thanks to HKS for suggesting the new features. --------------------------------------------------------------------------- Version 3.21.0 [DEVEL] (rgerhards), 2008-07-18 - starts a new devel branch - added a generic test driver for RainerScript plus some test cases to the testbench - added a small diagnostic tool to obtain result of gethostname() API - imported all changes from 3.18.1 until today (some quite important, see below) --------------------------------------------------------------------------- Version 3.20.6 [v3-stable] (rgerhards), 2009-04-16 - this is the last v3-stable for the 3.20.x series - bugfix: $InputTCPMaxSessions config directive was accepted, but not honored. This resulted in a fixed upper limit of 200 connections. - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html --------------------------------------------------------------------------- Version 3.20.5 [v3-stable] (rgerhards), 2009-04-02 - bugfix: potential abort with DA queue after high watermark is reached There exists a race condition that can lead to a segfault. Thanks go to vbernetr, who performed the analysis and provided patch, which I only tweaked a very little bit. - fixed bugs in RainerScript: o when converting a number and a string to a common type, both were actually converted to the other variable's type. o the value of rsCStrConvertToNumber() was miscalculated. Thanks to varmojfekoj for the patch - fixed a bug in configure.ac which resulted in problems with environment detection - thanks to Michael Biebl for the patch - fixed a potential segfault problem in gssapi code thanks to varmojfekoj for the patch - doc enhance: provide standard template for MySQL module and instructions on how to modify schema --------------------------------------------------------------------------- Version 3.20.4 [v3-stable] (rgerhards), 2009-02-09 - bugfix: inconsistent use of mutex/atomic operations could cause segfault details are too many, for full analysis see blog post at: http://blog.gerhards.net/2009/01/rsyslog-data-race-analysis.html - bugfix: invalid ./configure settings for RFC3195 thanks to Michael Biebl for the patch - bugfix: invalid mutex access in msg.c - doc bugfix: dist tarball missed 2 files, had one extra file that no longer belongs into it. Thanks to Michael Biebl for pointing this out. --------------------------------------------------------------------------- Version 3.20.3 [v3-stable] (rgerhards), 2009-01-19 - doc bugfix: v3-compatiblity document had typo in config directive thanks to Andrej for reporting this - fixed a potential segfault condition with $AllowedSender directive On HUP, the root pointers were not properly cleaned up. Thanks to Michael Biebel, olgoat, and Juha Koho for reporting and analyzing the bug. --------------------------------------------------------------------------- Version 3.20.2 [v3-stable] (rgerhards), 2008-12-04 - re-release of 3.20.1 with an additional fix, that could also lead to DoS; 3.20.1 has been removed from the official download archives - security fix: imudp emitted a message when a non-permitted sender tried to send a message to it. This behaviour is operator-configurable. If enabled, a message was emitted each time. That way an attacker could effectively fill the disk via this facility. The message is now emitted only once in a minute (this currently is a hard-coded limit, if someone comes up with a good reason to make it configurable, we will probably do that). --------------------------------------------------------------------------- Version 3.20.1 [v3-stable] (rgerhards), 2008-12-04 - security bugfix: $AllowedSender was not honored, all senders were permitted instead - enhance: regex nomatch option "ZERO" has been added This allows to return the string 0 if a regular expression is not found. This is probably useful for storing numerical values into database columns. - bugfix: memory leak in gtls netstream driver fixed memory was lost each time a TLS session was torn down. This could result in a considerable memory leak if it happened quite frequently (potential system crash condition) - doc update: documented how to specify multiple property replacer options + link to new online regex generator tool added - minor bufgfix: very small memory leak in gtls netstream driver around a handful of bytes (< 20) for each HUP - improved debug output for regular expressions inside property replacer RE's seem to be a big trouble spot and I would like to have more information inside the debug log. So I decided to add some additional debug strings permanently. --------------------------------------------------------------------------- Version 3.20.0 [v3-stable] (rgerhards), 2008-11-05 - this is the inital release of the 3.19.x branch as a stable release - bugfix: double-free in pctp netstream driver. Thank to varmojfeko for the patch --------------------------------------------------------------------------- Version 3.19.12 [BETA] (rgerhards), 2008-10-16 - bugfix: subseconds where not correctly extracted from a timestamp if that timestamp did not contain any subsecond information (the resulting string was garbagge but should have been "0", what it now is). - increased maximum size of a configuration statement to 4K (was 1K) - imported all fixes from the stable branch (quite a lot) - bugfix: (potentially big) memory leak on HUP if queues could not be drained before timeout - thanks to David Lang for pointing this out --------------------------------------------------------------------------- Version 3.19.11 [BETA] (rgerhards), 2008-08-25 This is a refresh of the beta. No beta-specific fixes have been added. - included fixes from v3-stable (most importantly 3.18.3) --------------------------------------------------------------------------- Version 3.19.10 [BETA] (rgerhards), 2008-07-15 - start of a new beta branch based on former 3.19 devel branch - bugfix: bad memory leak in disk-based queue modes - bugfix: UDP syslog forwarding did not work on all platforms the ai_socktype was incorrectly set to 1. On some platforms, this lead to failing name resolution (e.g. FreeBSD 7). Thanks to HKS for reporting the bug. - bugfix: priority was incorrectly calculated on FreeBSD 7, because the LOG_MAKEPRI() C macro has a different meaning there (it is just a simple addition of faciltity and severity). I have changed this to use own, consistent, code for PRI calculation. Thank to HKS for reporting this bug. - bugfix (cosmetical): authorization was not checked when gtls handshake completed immediately. While this sounds scary, the situation can not happen in practice. We use non-blocking IO only for server-based gtls session setup. As TLS requires the exchange of multiple frames before the handshake completes, it simply is impossible to do this in one step. However, it is useful to have the code path correct even for this case - otherwise, we may run into problems if the code is changed some time later (e.g. to use blocking sockets). Thanks to varmojfekoj for providing the patch. - important queue bugfix from 3.18.1 imported (see below) - cleanup of some debug messages --------------------------------------------------------------------------- Version 3.19.9 (rgerhards), 2008-07-07 - added tutorial for creating a TLS-secured syslog infrastructure - rewritten omusrmsg to no longer fork() a new process for sending messages this caused some problems with the threading model, e.g. zombies. Also, it was far less optimal than it is now. - bugfix: machine certificate was required for client even in TLS anon mode Reference: http://bugzilla.adiscon.com/show_bug.cgi?id=85 The fix also slightly improves performance by not storing certificates in client sessions when there is no need to do so. - bugfix: RainerScript syntax error was not always detected --------------------------------------------------------------------------- Version 3.19.8 (rgerhards), 2008-07-01 - bugfix: gtls module did not correctly handle EGAIN (and similar) recv() states. This has been fixed by introducing a new abstraction layer inside gtls. - added (internal) error codes to error messages; added redirector to web description of error codes closes bug http://bugzilla.adiscon.com/show_bug.cgi?id=20 - disabled compile warnings caused by third-party libraries - reduced number of compile warnings in gcc's -pedantic mode - some minor documentation improvements - included all fixes from beta 3.17.5 --------------------------------------------------------------------------- Version 3.19.7 (rgerhards), 2008-06-11 - added new property replacer option "date-subseconds" that enables to query just the subsecond part of a high-precision timestamp - somewhat improved plain tcp syslog reliability by doing a connection check before sending. Credits to Martin Schuette for providing the idea. Details are available at http://blog.gerhards.net/2008/06/reliable-plain-tcp-syslog-once-again.html - made rsyslog tickless in the (usual and default) case that repeated message reduction is turned off. More info: http://blog.gerhards.net/2008/06/coding-to-save-environment.html - some build system cleanup, thanks to Michael Biebl - bugfix: compile under (Free)BSD failed due to some invalid library definitions - this is fixed now. Thanks to Michael Biebl for the patch. --------------------------------------------------------------------------- Version 3.19.6 (rgerhards), 2008-06-06 - enhanced property replacer to support multiple regex matches - bugfix: part of permittedPeer structure was not correctly initialized thanks to varmojfekoj for spotting this - bugfix: off-by-one bug during certificate check - bugfix: removed some memory leaks in TLS code --------------------------------------------------------------------------- Version 3.19.5 (rgerhards), 2008-05-30 - enabled Posix ERE expressions inside the property replacer (previously BRE was permitted only) - provided ability to specify that a regular expression submatch shall be used inside the property replacer - implemented in property replacer: if a regular expression does not match, it can now either return "**NO MATCH** (default, as before), a blank property or the full original property text - enhanced property replacer to support multiple regex matches --------------------------------------------------------------------------- Version 3.19.4 (rgerhards), 2008-05-27 - implemented x509/certvalid gtls auth mode - implemented x509/name gtls auth mode (including wildcards) - changed fingerprint gtls auth mode to new format fingerprint - protected gtls error string function by a mutex. Without it, we could have a race condition in extreme cases. This was very remote, but now can no longer happen. - changed config directive name to reflect different use $ActionSendStreamDriverCertFingerprint is now $ActionSendStreamDriverPermittedPeer and can be used both for fingerprint and name authentication (similar to the input side) - bugfix: sender information (fromhost et al) was missing in imudp thanks to sandiso for reporting this bug - this release fully inplements IETF's syslog-transport-tls-12 plus the latest text changes Joe Salowey provided via email. Not included is ipAddress subjectAltName authentication, which I think will be dropped from the draft. I don't think there is any real need for it. This release also includes all bug fix up to today from the beta and stable branches. Most importantly, this means the bugfix for 100% CPU utilization by imklog. --------------------------------------------------------------------------- Version 3.19.3 (rgerhards), 2008-05-21 - added ability to authenticate the server against its certificate fingerprint - added ability for client to provide its fingerprint - added ability for server to obtain client cert's fingerprint - bugfix: small mem leak in omfwd on exit (strmdriver name was not freed) - bugfix: $ActionSendStreamDriver had no effect - bugfix: default syslog port was no longer used if none was configured. Thanks to varmojfekoj for the patch - bugfix: missing linker options caused build to fail on some systems. Thanks to Tiziano Mueller for the patch. --------------------------------------------------------------------------- Version 3.19.2 (rgerhards), 2008-05-16 - bugfix: TCP input modules did incorrectly set fromhost property (always blank) - bugfix: imklog did not set fromhost property - added "fromhost-ip" property Note that adding this property changes the on-disk format for messages. However, that should not have any bad effect on existing spool files. But you will run into trouble if you create a spool file with this version and then try to process it with an older one (after a downgrade). Don't do that ;) - added "RSYSLOG_DebugFormat" canned template - bugfix: hostname and fromhost were swapped when a persisted message (in queued mode) was read in - bugfix: lmtcpclt, lmtcpsrv and lmgssutil did all link to the static runtime library, resulting in a large size increase (and potential "interesting" effects). Thanks to Michael Biebel for reporting the size issue. - bugfix: TLS server went into an endless loop in some situations. Thanks to Michael Biebl for reporting the problem. - fixed potential segfault due to invalid call to cfsysline thanks to varmojfekoj for the patch --------------------------------------------------------------------------- Version 3.19.1 (rgerhards), 2008-05-07 - configure help for --enable-gnutls wrong - said default is "yes" but default actually is "no" - thanks to darix for pointing this out - file dirty.h was missing - thanks to darix for pointing this out - bugfix: man files were not properly distributed - thanks to darix for reporting and to Michael Biebl for help with the fix - some minor cleanup --------------------------------------------------------------------------- Version 3.19.0 (rgerhards), 2008-05-06 - begins new devel branch version - implemented TLS for plain tcp syslog (this is also the world's first implementation of IETF's upcoming syslog-transport-tls draft) - partly rewritten and improved omfwd among others, now loads TCP code only if this is actually necessary - split of a "runtime library" for rsyslog - this is not yet a clean model, because some modularization is still outstanding. In theory, this shall enable other utilities but rsyslogd to use the same runtime - implemented im3195, the RFC3195 input as a plugin - changed directory structure, files are now better organized - a lot of cleanup in regard to modularization - -c option no longer must be the first option - thanks to varmjofekoj for the patch --------------------------------------------------------------------------- Version 3.18.7 (rgerhards), 2008-12-?? - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html - fixed a potential segfault condition with $AllowedSender directive On HUP, the root pointers were not properly cleaned up. Thanks to Michael Biebel, olgoat, and Juha Koho for reporting and analyzing the bug. - some legacy options were not correctly processed. Thanks to varmojfekoj for the patch. - doc bugfix: some spelling errors in man pages corrected. Thanks to Geoff Simmons for the patch. --------------------------------------------------------------------------- Version 3.18.6 (rgerhards), 2008-12-08 - security bugfix: $AllowedSender was not honored, all senders were permitted instead (see http://www.rsyslog.com/Article322.phtml) (backport from v3-stable, v3.20.9) - minor bugfix: dual close() call on tcp session closure --------------------------------------------------------------------------- Version 3.18.5 (rgerhards), 2008-10-09 - bugfix: imudp input module could cause segfault on HUP It did not properly de-init a variable acting as a linked list head. That resulted in trying to access freed memory blocks after the HUP. - bugfix: rsyslogd could hang on HUP because getnameinfo() is not cancel-safe, but was not guarded against being cancelled. pthread_cancel() is routinely being called during HUP processing. - bugfix[minor]: if queue size reached light_delay mark, enqueuing could potentially be blocked for a longer period of time, which was not the behaviour desired. - doc bugfix: $ActionExecOnlyWhenPreviousIsSuspended was still misspelled as $...OnlyIfPrev... in some parts of the documentation. Thanks to Lorenzo M. Catucci for reporting this bug. - added doc on malformed messages, cause and how to work-around, to the doc set - added doc on how to build from source repository --------------------------------------------------------------------------- Version 3.18.4 (rgerhards), 2008-09-18 - bugfix: order-of magnitude issue with base-10 size definitions in config file parser. Could lead to invalid sizes, constraints etc for e.g. queue files and any other object whose size was specified in base-10 entities. Did not apply to binary entities. Thanks to RB for finding this bug and providing a patch. - bugfix: action was not called when system time was set backwards (until the previous time was reached again). There are still some side-effects when time is rolled back (A time rollback is really a bad thing to do, ideally the OS should issue pseudo time (like NetWare did) when the user tries to roll back time). Thanks to varmojfekoj for this patch. - doc bugfix: rsyslog.conf man page improved and minor nit fixed thanks to Lukas Kuklinek for the patch. - bugfix: error code -2025 was used for two different errors. queue full is now -2074 and -2025 is unique again. (did cause no real problem except for troubleshooting) - bugfix: default discard severity was incorrectly set to 4, which lead to discard-on-queue-full to be enabled by default. That could cause message loss where non was expected. The default has now been changed to the correct value of 8, which disables the functionality. This problem applied both to the main message queue and the action queues. Thanks to Raoul Bhatia for pointing out this problem. - bugfix: option value for legacy -a option could not be specified, resulting in strange operations. Thanks to Marius Tomaschewski for the patch. - bugfix: colon after date should be ignored, but was not. This has now been corrected. Required change to the internal ParseTIMESTAMP3164() interface. --------------------------------------------------------------------------- Version 3.18.3 (rgerhards), 2008-08-18 - bugfix: imfile could cause a segfault upon rsyslogd HUP and termination Thanks to lperr for an excellent bug report that helped detect this problem. - enhanced ommysql to support custom port to connect to server Port can be set via new $ActionOmmysqlServerPort config directive Note: this was a very minor change and thus deemed appropriate to be done in the stable release. - bugfix: misspelled config directive, previously was $MainMsgQueueWorkeTimeoutrThreadShutdown, is now $MainMsgQueueWorkerTimeoutThreadShutdown. Note that the misspelled directive is not preserved - if the misspelled directive was used (which I consider highly unlikely), the config file must be changed. Thanks to lperr for reporting the bug. - disabled flow control for imuxsock, as it could cause system hangs under some circumstances. The devel (3.21.3 and above) will re-enable it and provide enhanced configurability to overcome the problems if they occur. --------------------------------------------------------------------------- Version 3.18.2 (rgerhards), 2008-08-08 - merged in IPv6 forwarding address bugfix from v2-stable --------------------------------------------------------------------------- Version 3.18.1 (rgerhards), 2008-07-21 - bugfix: potential segfault in creating message mutex in non-direct queue mode. rsyslogd segfaults on freeeBSD 7.0 (an potentially other platforms) if an action queue is running in any other mode than non-direct. The same problem can potentially be triggered by some main message queue settings. In any case, it will manifest during rsylog's startup. It is unlikely to happen after a successful startup (the only window of exposure may be a relatively seldom executed action running in queued mode). This has been corrected. Thank to HKS for point out the problem. - bugfix: priority was incorrectly calculated on FreeBSD 7, because the LOG_MAKEPRI() C macro has a different meaning there (it is just a simple addition of faciltity and severity). I have changed this to use own, consistent, code for PRI calculation. [Backport from 3.19.10] - bugfix: remove PRI part from kernel message if it is present Thanks to Michael Biebl for reporting this bug - bugfix: mark messages were not correctly written to text log files the markmessageinterval was not correctly propagated to all places where it was needed. This resulted in rsyslog using the default (20 minutes) in some code pathes, what looked to the user like mark messages were never written. - added a new property replacer option "sp-if-no-1st-sp" to cover a problem with RFC 3164 based interpreation of tag separation. While it is a generic approach, it fixes a format problem introduced in 3.18.0, where kernel messages no longer had a space after the tag. This is done by a modifcation of the default templates. Please note that this may affect some messages where there intentionally is no space between the tag and the first character of the message content. If so, this needs to be worked around via a specific template. However, we consider this scenario to be quite remote and, even if it exists, it is not expected that it will actually cause problems with log parsers (instead, we assume the new default template behaviour may fix previous problems with log parsers due to the missing space). - bugfix: imklog module was not correctly compiled for GNU/kFreeBSD. Thanks to Petr Salinger for the patch - doc bugfix: property replacer options secpath-replace and secpath-drop were not documented - doc bugfix: fixed some typos in rsyslog.conf man page - fixed typo in source comment - thanks to Rio Fujita - some general cleanup (thanks to Michael Biebl) --------------------------------------------------------------------------- Version 3.18.0 (rgerhards), 2008-07-11 - begun a new v3-stable based on former 3.17.4 beta plus patches to previous v3-stable - bugfix in RainerScript: syntax error was not always detected --------------------------------------------------------------------------- Version 3.17.5 (rgerhards), 2008-06-27 - added doc: howto set up a reliable connection to remote server via queued mode (and plain tcp protocol) - bugfix: comments after actions were not properly treated. For some actions (e.g. forwarding), this could also lead to invalid configuration --------------------------------------------------------------------------- Version 3.17.4 (rgerhards), 2008-06-16 - changed default for $KlogSymbolLookup to "off". The directive is also scheduled for removal in a later version. This was necessary because on kernels >= 2.6, the kernel does the symbol lookup itself. The imklog lookup logic then breaks the log message and makes it unusable. --------------------------------------------------------------------------- Version 3.17.3 (rgerhards), 2008-05-28 - bugfix: imklog went into an endless loop if a PRI value was inside a kernel log message (unusual case under Linux, frequent under BSD) --------------------------------------------------------------------------- Version 3.17.2 (rgerhards), 2008-05-04 - this version is the new beta, based on 3.17.1 devel feature set - merged in imklog bug fix from v3-stable (3.16.1) --------------------------------------------------------------------------- Version 3.17.1 (rgerhards), 2008-04-15 - removed dependency on MAXHOSTNAMELEN as much as it made sense. GNU/Hurd does not define it (because it has no limit), and we have taken care for cases where it is undefined now. However, some very few places remain where IMHO it currently is not worth fixing the code. If it is not defined, we have used a generous value of 1K, which is above IETF RFC's on hostname length at all. The memory consumption is no issue, as there are only a handful of this buffers allocated *per run* -- that's also the main reason why we consider it not worth to be fixed any further. - enhanced legacy syslog parser to handle slightly malformed messages (with a space in front of the timestamp) - at least HP procurve is known to do that and I won't outrule that others also do it. The change looks quite unintrusive and so we added it to the parser. - implemented klogd functionality for BSD - implemented high precision timestamps for the kernel log. Thanks to Michael Biebl for pointing out that the kernel log did not have them. - provided ability to discard non-kernel messages if they are present in the kernel log (seems to happen on BSD) - implemented $KLogInternalMsgFacility config directive - implemented $KLogPermitNonKernelFacility config directive Plus a number of bugfixes that were applied to v3-stable and beta branches (not mentioned here in detail). --------------------------------------------------------------------------- Version 3.17.0 (rgerhards), 2008-04-08 - added native ability to send mail messages - removed no longer needed file relptuil.c/.h - added $ActionExecOnlyOnceEveryInterval config directive - bugfix: memory leaks in script engine - bugfix: zero-length strings were not supported in object deserializer - properties are now case-insensitive everywhere (script, filters, templates) - added the capability to specify a processing (actually dequeue) timeframe with queues - so things can be configured to be done at off-peak hours - We have removed the 32 character size limit (from RFC3164) on the tag. This had bad effects on existing envrionments, as sysklogd didn't obey it either (probably another bug in RFC3164...). We now receive the full size, but will modify the outputs so that only 32 characters max are used by default. If you need large tags in the output, you need to provide custom templates. - changed command line processing. -v, -M, -c options are now parsed and processed before all other options. Inter-option dependencies have been relieved. Among others, permits to specify intial module load path via -M only (not the environment) which makes it much easier to work with non-standard module library locations. Thanks to varmojfekoj for suggesting this change. Matches bugzilla bug 55. - bugfix: some messages were emited without hostname Plus a number of bugfixes that were applied to v3-stable and beta branches (not mentioned here in detail). --------------------------------------------------------------------------- Version 3.16.3 (rgerhards), 2008-07-11 - updated information on rsyslog packages - bugfix: memory leak in disk-based queue modes --------------------------------------------------------------------------- Version 3.16.2 (rgerhards), 2008-06-25 - fixed potential segfault due to invalid call to cfsysline thanks to varmojfekoj for the patch - bugfix: some whitespaces where incorrectly not ignored when parsing the config file. This is now corrected. Thanks to Michael Biebl for pointing out the problem. --------------------------------------------------------------------------- Version 3.16.1 (rgerhards), 2008-05-02 - fixed a bug in imklog which lead to startup problems (including segfault) on some platforms under some circumsances. Thanks to Vieri for reporting this bug and helping to troubleshoot it. --------------------------------------------------------------------------- Version 3.16.0 (rgerhards), 2008-04-24 - new v3-stable (3.16.x) based on beta 3.15.x (RELP support) - bugfix: omsnmp had a too-small sized buffer for hostname+port. This could not lead to a segfault, as snprintf() was used, but could cause some trouble with extensively long hostnames. - applied patch from Tiziano Müller to remove some compiler warnings - added gssapi overview/howto thanks to Peter Vrabec - changed some files to grant LGPLv3 extended persmissions on top of GPLv3 this also is the first sign of something that will evolve into a well-defined "rsyslog runtime library" --------------------------------------------------------------------------- Version 3.15.1 (rgerhards), 2008-04-11 - bugfix: some messages were emited without hostname - disabled atomic operations for the time being because they introduce some cross-platform trouble - need to see how to fix this in the best possible way - bugfix: zero-length strings were not supported in object deserializer - added librelp check via PKG_CHECK thanks to Michael Biebl's patch - file relputil.c deleted, is not actually needed - added more meaningful error messages to rsyslogd (when some errors happens during startup) - bugfix: memory leaks in script engine - bugfix: $hostname and $fromhost in RainerScript did not work This release also includes all changes applied to the stable versions up to today. --------------------------------------------------------------------------- Version 3.15.0 (rgerhards), 2008-04-01 - major new feature: imrelp/omrelp support reliable delivery of syslog messages via the RELP protocol and librelp (http://www.librelp.com). Plain tcp syslog, so far the best reliability solution, can lose messages when something goes wrong or a peer goes down. With RELP, this can no longer happen. See imrelp.html for more details. - bugfix: rsyslogd was no longer build by default; man pages are only installed if corresponding option is selected. Thanks to Michael Biebl for pointing these problems out. --------------------------------------------------------------------------- Version 3.14.2 (rgerhards), 2008-04-09 - bugfix: segfault with expression-based filters - bugfix: omsnmp did not deref errmsg object on exit (no bad effects caused) - some cleanup - bugfix: imklog did not work well with kernel 2.6+. Thanks to Peter Vrabec for patching it based on the development in sysklogd - and thanks to the sysklogd project for upgrading klogd to support the new functionality - some cleanup in imklog - bugfix: potential segfault in imklog when kernel is compiled without /proc/kallsyms and the file System.map is missing. Thanks to Andrea Morandi for pointing it out and suggesting a fix. - bugfixes, credits to varmojfekoj: * reset errno before printing a warning message * misspelled directive name in code processing legacy options - bugfix: some legacy options not correctly interpreted - thanks to varmojfekoj for the patch - improved detection of modules being loaded more than once thanks to varmojfekoj for the patch --------------------------------------------------------------------------- Version 3.14.1 (rgerhards), 2008-04-04 - bugfix: some messages were emited without hostname - bugfix: rsyslogd was no longer build by default; man pages are only installed if corresponding option is selected. Thanks to Michael Biebl for pointing these problems out. - bugfix: zero-length strings were not supported in object deserializer - disabled atomic operations for this stable build as it caused platform problems - bugfix: memory leaks in script engine - bugfix: $hostname and $fromhost in RainerScript did not work - bugfix: some memory leak when queue is runing in disk mode - man pages improved thanks to varmofekoj and Peter Vrabec - We have removed the 32 character size limit (from RFC3164) on the tag. This had bad effects on existing envrionments, as sysklogd didn't obey it either (probably another bug in RFC3164...). We now receive the full size, but will modify the outputs so that only 32 characters max are used by default. If you need large tags in the output, you need to provide custom templates. - bugfix: some memory leak when queue is runing in disk mode --------------------------------------------------------------------------- Version 3.14.0 (rgerhards), 2008-04-02 An interim version was accidently released to the web. It was named 3.14.0. To avoid confusion, we have not assigned this version number to any official release. If you happen to use 3.14.0, please update to 3.14.1. --------------------------------------------------------------------------- Version 3.13.0-dev0 (rgerhards), 2008-03-31 - bugfix: accidently set debug option in 3.12.5 reset to production This option prevented dlclose() to be called. It had no real bad effects, as the modules were otherwise correctly deinitialized and dlopen() supports multiple opens of the same module without any memory footprint. - removed --enable-mudflap, added --enable-valgrind ./configure setting - bugfix: tcp receiver could segfault due to uninitialized variable - docfix: queue doc had a wrong directive name that prevented max worker threads to be correctly set - worked a bit on atomic memory operations to support problem-free threading (only at non-intrusive places) - added a --enable/disable-rsyslogd configure option so that source-based packaging systems can build plugins without the need to compile rsyslogd - some cleanup - test of potential new version number scheme --------------------------------------------------------------------------- Version 3.12.5 (rgerhards), 2008-03-28 - changed default for "last message repeated n times", which is now off by default - implemented backward compatibility commandline option parsing - automatically generated compatibility config lines are now also logged so that a user can diagnose problems with them - added compatibility mode for -a, -o and -p options - compatibility mode processing finished - changed default file output format to include high-precision timestamps - added a buid-in template for previous syslogd file format - added new $ActionFileDefaultTemplate directive - added support for high-precision timestamps when receiving legacy syslog messages - added new $ActionForwardDefaultTemplate directive - added new $ActionGSSForwardDefaultTemplate directive - added build-in templates for easier configuration - bugfix: fixed small memory leak in tcpclt.c - bugfix: fixed small memory leak in template regular expressions - bugfix: regular expressions inside property replacer did not work properly - bugfix: QHOUR and HHOUR properties were wrongly calculated - bugfix: fixed memory leaks in stream class and imfile - bugfix: $ModDir did invalid bounds checking, potential overlow in dbgprintf() - thanks to varmojfekoj for the patch - bugfix: -t and -g legacy options max number of sessions had a wrong and much too high value --------------------------------------------------------------------------- Version 3.12.4 (rgerhards), 2008-03-25 - Greatly enhanced rsyslogd's file write performance by disabling file syncing capability of output modules by default. This feature is usually not required, not useful and an extreme performance hit (both to rsyslogd as well as the system at large). Unfortunately, most users enable it by default, because it was most intuitive to enable it in plain old sysklogd syslog.conf format. There is now the $ActionFileEnableSync config setting which must be enabled in order to support syncing. By default it is off. So even if the old-format config lines request syncing, it is not done unless explicitely enabled. I am sure this is a very useful change and not a risk at all. I need to think if I undo it under compatibility mode, but currently this does not happen (I fear a lot of lazy users will run rsyslogd in compatibility mode, again bringing up this performance problem...). - added flow control options to other input sources - added $HHOUR and $QHOUR system properties - can be used for half- and quarter-hour logfile rotation - changed queue's discard severities default value to 8 (do not discard) to prevent unintentional message loss - removed a no-longer needed callback from the output module interface. Results in reduced code complexity. - bugfix/doc: removed no longer supported -h option from man page - bugfix: imklog leaked several hundered KB on each HUP. Thanks to varmojfekoj for the patch - bugfix: potential segfault on module unload. Thanks to varmojfekoj for the patch - bugfix: fixed some minor memory leaks - bugfix: fixed some slightly invalid memory accesses - bugfix: internally generated messages had "FROMHOST" property not set --------------------------------------------------------------------------- Version 3.12.3 (rgerhards), 2008-03-18 - added advanced flow control for congestion cases (mode depending on message source and its capablity to be delayed without bad side effects) - bugfix: $ModDir should not be reset on $ResetConfig - this can cause a lot of confusion and there is no real good reason to do so. Also conflicts with the new -M option and environment setting. - bugfix: TCP and GSSAPI framing mode variable was uninitialized, leading to wrong framing (caused, among others, interop problems) - bugfix: TCP (and GSSAPI) octet-counted frame did not work correctly in all situations. If the header was split across two packet reads, it was invalidly processed, causing loss or modification of messages. - bugfix: memory leak in imfile - bugfix: duplicate public symbol in omfwd and omgssapi could lead to segfault. thanks to varmojfekoj for the patch. - bugfix: rsyslogd aborted on sigup - thanks to varmojfekoj for the patch - some more internal cleanup ;) - begun relp modules, but these are not functional yet - Greatly enhanced rsyslogd's file write performance by disabling file syncing capability of output modules by default. This feature is usually not required, not useful and an extreme performance hit (both to rsyslogd as well as the system at large). Unfortunately, most users enable it by default, because it was most intuitive to enable it in plain old sysklogd syslog.conf format. There is now a new config setting which must be enabled in order to support syncing. By default it is off. So even if the old-format config lines request syncing, it is not done unless explicitely enabled. I am sure this is a very useful change and not a risk at all. I need to think if I undo it under compatibility mode, but currently this does not happen (I fear a lot of lazy users will run rsyslogd in compatibility mode, again bringing up this performance problem...). --------------------------------------------------------------------------- Version 3.12.2 (rgerhards), 2008-03-13 - added RSYSLOGD_MODDIR environment variable - added -M rsyslogd option (allows to specify module directory location) - converted net.c into a loadable library plugin - bugfix: debug module now survives unload of loadable module when printing out function call data - bugfix: not properly initialized data could cause several segfaults if there were errors in the config file - thanks to varmojfekoj for the patch - bugfix: rsyslogd segfaulted when imfile read an empty line - thanks to Johnny Tan for an excellent bug report - implemented dynamic module unload capability (not visible to end user) - some more internal cleanup - bugfix: imgssapi segfaulted under some conditions; this fix is actually not just a fix but a change in the object model. Thanks to varmojfekoj for providing the bug report, an initial fix and lots of good discussion that lead to where we finally ended up. - improved session recovery when outbound tcp connection breaks, reduces probability of message loss at the price of a highly unlikely potential (single) message duplication --------------------------------------------------------------------------- Version 3.12.1 (rgerhards), 2008-03-06 - added library plugins, which can be automatically loaded - bugfix: actions were not correctly retried; caused message loss - changed module loader to automatically add ".so" suffix if not specified (over time, this shall also ease portability of config files) - improved debugging support; debug runtime options can now be set via an environment variable - bugfix: removed debugging code that I forgot to remove before releasing 3.12.0 (does not cause harm and happened only during startup) - added support for the MonitorWare syslog MIB to omsnmp - internal code improvements (more code converted into classes) - internal code reworking of the imtcp/imgssapi module - added capability to ignore client-provided timestamp on unix sockets and made this mode the default; this was needed, as some programs (e.g. sshd) log with inconsistent timezone information, what messes up the local logs (which by default don't even contain time zone information). This seems to be consistent with what sysklogd did for the past four years. Alternate behaviour may be desirable if gateway-like processes send messages via the local log slot - in this case, it can be enabled via the $InputUnixListenSocketIgnoreMsgTimestamp and $SystemLogSocketIgnoreMsgTimestamp config directives - added ability to compile on HP UX; verified that imudp worked on HP UX; however, we are still in need of people trying out rsyslogd on HP UX, so it can not yet be assumed it runs there - improved session recovery when outbound tcp connection breaks, reduces probability of message loss at the price of a highly unlikely potential (single) message duplication --------------------------------------------------------------------------- Version 3.12.0 (rgerhards), 2008-02-28 - added full expression support for filters; filters can now contain arbitrary complex boolean, string and arithmetic expressions --------------------------------------------------------------------------- Version 3.11.6 (rgerhards), 2008-02-27 - bugfix: gssapi libraries were still linked to rsyslog core, what should no longer be necessary. Applied fix by Michael Biebl to solve this. - enabled imgssapi to be loaded side-by-side with imtcp - added InputGSSServerPermitPlainTCP config directive - split imgssapi source code somewhat from imtcp - bugfix: queue cancel cleanup handler could be called with invalid pointer if dequeue failed - bugfix: rsyslogd segfaulted on second SIGHUP tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=38 - improved stability of queue engine - bugfix: queue disk file were not properly persisted when immediately after closing an output file rsyslog was stopped or huped (the new output file open must NOT have happend at that point) - this lead to a sparse and invalid queue file which could cause several problems to the engine (unpredictable results). This situation should have happened only in very rare cases. tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=40 - bugfix: during queue shutdown, an assert invalidly triggered when the primary queue's DA worker was terminated while the DA queue's regular worker was still executing. This could result in a segfault during shutdown. tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=41 - bugfix: queue properties sizeOnDisk, bytesRead were persisted to disk with wrong data type (long instead of int64) - could cause problems on 32 bit machines - bugfix: queue aborted when it was shut down, DA-enabled, DA mode was just initiated but not fully initialized (a race condition) - bugfix: imfile could abort under extreme stress conditions (when it was terminated before it could open all of its to be monitored files) - applied patch from varmojfekoj to fix an issue with compatibility mode and default module directories (many thanks!): I've also noticed a bug in the compatibility code; the problem is that options are parsed before configuration file so options which need a module to be loaded will currently ignore any $moddir directive. This can be fixed by moving legacyOptsHook() after config file parsing. (see the attached patch) This goes against the logical order of processing, but the legacy options are only few and it doesn't seem to be a problem. - bugfix: object property deserializer did not handle negative numbers --------------------------------------------------------------------------- Version 3.11.5 (rgerhards), 2008-02-25 - new imgssapi module, changed imtcp module - this enables to load/package GSSAPI support separately - thanks to varmojfekoj for the patch - compatibility mode (the -c option series) is now at least partly completed - thanks to varmojfekoj for the patch - documentation for imgssapi and imtcp added - duplicate $ModLoad's for the same module are now detected and rejected -- thanks to varmojfekoj for the patch --------------------------------------------------------------------------- Version 3.11.4 (rgerhards), 2008-02-21 - bugfix: debug.html was missing from release tarball - thanks to Michael Biebl for bringing this to my attention - some internal cleanup on the stringbuf object calling interface - general code cleanup and further modularization - $MainMessageQueueDiscardSeverity can now also handle textual severities (previously only integers) - bugfix: message object was not properly synchronized when the main queue had a single thread and non-direct action queues were used - some documentation improvements --------------------------------------------------------------------------- Version 3.11.3 (rgerhards), 2008-02-18 - fixed a bug in imklog which lead to duplicate message content in kernel logs - added support for better plugin handling in libdbi (we contributed a patch to do that, we just now need to wait for the next libdbi version) - bugfix: fixed abort when invalid template was provided to an action bug http://bugzilla.adiscon.com/show_bug.cgi?id=4 - re-instantiated SIGUSR1 function; added SIGUSR2 to generate debug status output - added some documentation on runtime-debug settings - slightly improved man pages for novice users --------------------------------------------------------------------------- Version 3.11.2 (rgerhards), 2008-02-15 - added the capability to monitor text files and process their content as syslog messages (including forwarding) - added support for libdbi, a database abstraction layer. rsyslog now also supports the following databases via dbi drivers: * Firebird/Interbase * FreeTDS (access to MS SQL Server and Sybase) * SQLite/SQLite3 * Ingres (experimental) * mSQL (experimental) * Oracle (experimental) Additional drivers may be provided by the libdbi-drivers project, which can be used by rsyslog as soon as they become available. - removed some left-over unnecessary dbgprintf's (cluttered screen, cosmetic) - doc bugfix: html documentation for omsnmp was missing --------------------------------------------------------------------------- Version 3.11.1 (rgerhards), 2008-02-12 - SNMP trap sender added thanks to Andre Lorbach (omsnmp) - added input-plugin interface specification in form of a (copy) template input module - applied documentation fix by Michael Biebl -- many thanks! - bugfix: immark did not have MARK flags set... - added x-info field to rsyslogd startup/shutdown message. Hopefully points users to right location for further info (many don't even know they run rsyslog ;)) - bugfix: trailing ":" of tag was lost while parsing legacy syslog messages without timestamp - thanks to Anders Blomdell for providing a patch! - fixed a bug in stringbuf.c related to STRINGBUF_TRIM_ALLOCSIZE, which wasn't supposed to be used with rsyslog. Put a warning message up that tells this feature is not tested and probably not worth the effort. Thanks to Anders Blomdell fro bringing this to our attention - somewhat improved performance of string buffers - fixed bug that caused invalid treatment of tabs (HT) in rsyslog.conf - bugfix: setting for $EscapeCopntrolCharactersOnReceive was not properly initialized - clarified usage of space-cc property replacer option - improved abort diagnostic handler - some initial effort for malloc/free runtime debugging support - bugfix: using dynafile actions caused rsyslogd abort - fixed minor man errors thanks to Michael Biebl --------------------------------------------------------------------------- Version 3.11.0 (rgerhards), 2008-01-31 - implemented queued actions - implemented simple rate limiting for actions - implemented deliberate discarding of lower priority messages over higher priority ones when a queue runs out of space - implemented disk quotas for disk queues - implemented the $ActionResumeRetryCount config directive - added $ActionQueueFilename config directive - added $ActionQueueSize config directive - added $ActionQueueHighWaterMark config directive - added $ActionQueueLowWaterMark config directive - added $ActionQueueDiscardMark config directive - added $ActionQueueDiscardSeverity config directive - added $ActionQueueCheckpointInterval config directive - added $ActionQueueType config directive - added $ActionQueueWorkerThreads config directive - added $ActionQueueTimeoutshutdown config directive - added $ActionQueueTimeoutActionCompletion config directive - added $ActionQueueTimeoutenQueue config directive - added $ActionQueueTimeoutworkerThreadShutdown config directive - added $ActionQueueWorkerThreadMinimumMessages config directive - added $ActionQueueMaxFileSize config directive - added $ActionQueueSaveonShutdown config directive - addded $ActionQueueDequeueSlowdown config directive - addded $MainMsgQueueDequeueSlowdown config directive - bugfix: added forgotten docs to package - improved debugging support - fixed a bug that caused $MainMsgQueueCheckpointInterval to work incorrectly - when a long-running action needs to be cancelled on shutdown, the message that was processed by it is now preserved. This finishes support for guaranteed delivery of messages (if the output supports it, of course) - fixed bug in output module interface, see http://sourceforge.net/tracker/index.php?func=detail&aid=1881008&group_id=123448&atid=696552 - changed the ommysql output plugin so that the (lengthy) connection initialization now takes place in message processing. This works much better with the new queued action mode (fast startup) - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! - bugfixed stream class offset handling on 32bit platforms --------------------------------------------------------------------------- Version 3.10.3 (rgerhards), 2008-01-28 - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - run-time instrumentation added - implemented disk-assisted queue mode, which enables on-demand disk spooling if the queue's in-memory queue is exhausted - implemented a dynamic worker thread pool for processing incoming messages; workers are started and shut down as need arises - implemented a run-time instrumentation debug package - implemented the $MainMsgQueueSaveOnShutdown config directive - implemented the $MainMsgQueueWorkerThreadMinimumMessages config directive - implemented the $MainMsgQueueTimeoutWorkerThreadShutdown config directive --------------------------------------------------------------------------- Version 3.10.2 (rgerhards), 2008-01-14 - added the ability to keep stop rsyslogd without the need to drain the main message queue. In disk queue mode, rsyslog continues to run from the point where it stopped. In case of a system failure, it continues to process messages from the last checkpoint. - fixed a bug that caused a segfault on startup when no $WorkDir directive was specified in rsyslog.conf - provided more fine-grain control over shutdown timeouts and added a way to specify the enqueue timeout when the main message queue is full - implemented $MainMsgQueueCheckpointInterval config directive - implemented $MainMsgQueueTimeoutActionCompletion config directive - implemented $MainMsgQueueTimeoutEnqueue config directive - implemented $MainMsgQueueTimeoutShutdown config directive --------------------------------------------------------------------------- Version 3.10.1 (rgerhards), 2008-01-10 - implemented the "disk" queue mode. However, it currently is of very limited use, because it does not support persistence over rsyslogd runs. So when rsyslogd is stopped, the queue is drained just as with the in-memory queue modes. Persistent queues will be a feature of the next release. - performance-optimized string class, should bring an overall improvement - fixed a memory leak in imudp -- thanks to varmojfekoj for the patch - fixed a race condition that could lead to a rsyslogd hang when during HUP or termination - done some doc updates - added $WorkDirectory config directive - added $MainMsgQueueFileName config directive - added $MainMsgQueueMaxFileSize config directive --------------------------------------------------------------------------- Version 3.10.0 (rgerhards), 2008-01-07 - implemented input module interface and initial input modules - enhanced threading for input modules (each on its own thread now) - ability to bind UDP listeners to specific local interfaces/ports and ability to run multiple of them concurrently - added ability to specify listen IP address for UDP syslog server - license changed to GPLv3 - mark messages are now provided by loadble module immark - rklogd is no longer provided. Its functionality has now been taken over by imklog, a loadable input module. This offers a much better integration into rsyslogd and makes sure that the kernel logger process is brought up and down at the appropriate times - enhanced $IncludeConfig directive to support wildcard characters (thanks to Michael Biebl) - all inputs are now implemented as loadable plugins - enhanced threading model: each input module now runs on its own thread - enhanced message queue which now supports different queueing methods (among others, this can be used for performance fine-tuning) - added a large number of new configuration directives for the new input modules - enhanced multi-threading utilizing a worker thread pool for the main message queue - compilation without pthreads is no longer supported - much cleaner code due to new objects and removal of single-threading mode --------------------------------------------------------------------------- Version 2.0.8 V2-STABLE (rgerhards), 2008-??-?? - bugfix: ompgsql did not detect problems in sql command execution this could cause loss of messages. The handling was correct if the connection broke, but not if there was a problem with statement execution. The most probable case for such a case would be invalid sql inside the template, and this is now much easier to diagnose. - doc bugfix: default for $DirCreateMode incorrectly stated --------------------------------------------------------------------------- Version 2.0.7 V2-STABLE (rgerhards), 2008-04-14 - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html - bugfix: "$CreateDirs off" also disabled file creation Thanks to William Tisater for analyzing this bug and providing a patch. The actual code change is heavily based on William's patch. - bugfix: memory leak in ompgsql Thanks to Ken for providing the patch - bugfix: potential memory leak in msg.c This one did not surface yet and the issue was actually found due to a problem in v4 - but better fix it here, too --------------------------------------------------------------------------- Version 2.0.6 V2-STABLE (rgerhards), 2008-08-07 - bugfix: memory leaks in rsyslogd, primarily in singlethread mode Thanks to Frederico Nunez for providing the fix - bugfix: copy&paste error lead to dangling if - this caused a very minor issue with re-formatting a RFC3164 date when the message was invalidly formatted and had a colon immediately after the date. This was in the code for some years (even v1 had it) and I think it never had any effect at all in practice. Though, it should be fixed - but definitely nothing to worry about. --------------------------------------------------------------------------- Version 2.0.6 V2-STABLE (rgerhards), 2008-08-07 - bugfix: IPv6 addresses could not be specified in forwarding actions New syntax @[addr]:port introduced to enable that. Root problem was IPv6 addresses contain colons. (backport from 3.21.3) --------------------------------------------------------------------------- Version 2.0.5 STABLE (rgerhards), 2008-05-15 - bugfix: regular expressions inside property replacer did not work properly - adapted to liblogging 0.7.1+ --------------------------------------------------------------------------- Version 2.0.4 STABLE (rgerhards), 2008-03-27 - bugfix: internally generated messages had "FROMHOST" property not set - bugfix: continue parsing if tag is oversize (discard oversize part) - thanks to mclaughlin77@gmail.com for the patch - added $HHOUR and $QHOUR system properties - can be used for half- and quarter-hour logfile rotation --------------------------------------------------------------------------- Version 2.0.3 STABLE (rgerhards), 2008-03-12 - bugfix: setting for $EscapeCopntrolCharactersOnReceive was not properly initialized - bugfix: resolved potential segfault condition on HUP (extremely unlikely to happen in practice), for details see tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=38 - improved the man pages a bit - thanks to Michael Biebl for the patch - bugfix: not properly initialized data could cause several segfaults if there were errors in the config file - thanks to varmojfekoj for the patch --------------------------------------------------------------------------- Version 2.0.2 STABLE (rgerhards), 2008-02-12 - fixed a bug that could cause invalid string handling via strerror_r varmojfekoj provided the patch - many thanks! - added x-info field to rsyslogd startup/shutdown message. Hopefully points users to right location for further info (many don't even know they run rsyslog ;)) - bugfix: suspended actions were not always properly resumed varmojfekoj provided the patch - many thanks! - bugfix: errno could be changed during mark processing, leading to invalid error messages when processing inputs. Thank to varmojfekoj for pointing out this problem. - bugfix: trailing ":" of tag was lost while parsing legacy syslog messages without timestamp - thanks to Anders Blomdell for providing a patch! - bugfix (doc): misspelled config directive, invalid signal info - applied some doc fixes from Michel Biebl and cleaned up some no longer needed files suggested by him - cleaned up stringbuf.c to fix an annoyance reported by Anders Blomdell - fixed bug that caused invalid treatment of tabs (HT) in rsyslog.conf --------------------------------------------------------------------------- Version 2.0.1 STABLE (rgerhards), 2008-01-24 - fixed a bug in integer conversion - but this function was never called, so it is not really a useful bug fix ;) - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! --------------------------------------------------------------------------- Version 2.0.0 STABLE (rgerhards), 2008-01-02 - re-release of 1.21.2 as STABLE with no modifications except some doc updates --------------------------------------------------------------------------- Version 1.21.2 (rgerhards), 2007-12-28 - created a gss-api output module. This keeps GSS-API code and TCP/UDP code separated. It is also important for forward- compatibility with v3. Please note that this change breaks compatibility with config files created for 1.21.0 and 1.21.1 - this was considered acceptable. - fixed an error in forwarding retry code (could lead to message corruption but surfaced very seldom) - increased portability for older platforms (AI_NUMERICSERV moved) - removed socket leak in omfwd.c - cross-platform patch for GSS-API compile problem on some platforms thanks to darix for the patch! --------------------------------------------------------------------------- Version 1.21.1 (rgerhards), 2007-12-23 - small doc fix for $IncludeConfig - fixed a bug in llDestroy() - bugfix: fixing memory leak when message queue is full and during parsing. Thanks to varmojfekoj for the patch. - bugfix: when compiled without network support, unix sockets were not properply closed - bugfix: memory leak in cfsysline.c/doGetWord() fixed --------------------------------------------------------------------------- Version 1.21.0 (rgerhards), 2007-12-19 - GSS-API support for syslog/TCP connections was added. Thanks to varmojfekoj for providing the patch with this functionality - code cleanup - enhanced $IncludeConfig directive to support wildcard filenames - changed some multithreading synchronization --------------------------------------------------------------------------- Version 1.20.1 (rgerhards), 2007-12-12 - corrected a debug setting that survived release. Caused TCP connections to be retried unnecessarily often. - When a hostname ACL was provided and DNS resolution for that name failed, ACL processing was stopped at that point. Thanks to mildew for the patch. Fedora Bugzilla: http://bugzilla.redhat.com/show_bug.cgi?id=395911 - fixed a potential race condition, see link for details: http://rgerhards.blogspot.com/2007/12/rsyslog-race-condition.html Note that the probability of problems from this bug was very remote - fixed a memory leak that happend when PostgreSQL date formats were used --------------------------------------------------------------------------- Version 1.20.0 (rgerhards), 2007-12-07 - an output module for postgres databases has been added. Thanks to sur5r for contributing this code - unloading dynamic modules has been cleaned up, we now have a real implementation and not just a dummy "good enough for the time being". - enhanced platform independence - thanks to Bartosz Kuzma and Michael Biebl for their very useful contributions - some general code cleanup (including warnings on 64 platforms, only) --------------------------------------------------------------------------- Version 1.19.12 (rgerhards), 2007-12-03 - cleaned up the build system (thanks to Michael Biebl for the patch) - fixed a bug where ommysql was still not compiled with -pthread option --------------------------------------------------------------------------- Version 1.19.11 (rgerhards), 2007-11-29 - applied -pthread option to build when building for multi-threading mode hopefully solves an issue with segfaulting --------------------------------------------------------------------------- Version 1.19.10 (rgerhards), 2007-10-19 - introdcued the new ":modulename:" syntax for calling module actions in selector lines; modified ommysql to support it. This is primarily an aid for further modules and a prequisite to actually allow third party modules to be created. - minor fix in slackware startup script, "-r 0" is now "-r0" - updated rsyslogd doc set man page; now in html format - undid creation of a separate thread for the main loop -- this did not turn out to be needed or useful, so reduce complexity once again. - added doc fixes provided by Michael Biebl - thanks --------------------------------------------------------------------------- Version 1.19.9 (rgerhards), 2007-10-12 - now packaging system which again contains all components in a single tarball - modularized main() a bit more, resulting in less complex code - experimentally added an additional thread - will see if that affects the segfault bug we experience on some platforms. Note that this change is scheduled to be removed again later. --------------------------------------------------------------------------- Version 1.19.8 (rgerhards), 2007-09-27 - improved repeated message processing - applied patch provided by varmojfekoj to support building ommysql in its own way (now also resides in a plugin subdirectory); ommysql is now a separate package - fixed a bug in cvthname() that lead to message loss if part of the source hostname would have been dropped - created some support for distributing ommysql together with the main rsyslog package. I need to re-think it in the future, but for the time being the current mode is best. I now simply include one additional tarball for ommysql inside the main distribution. I look forward to user feedback on how this should be done best. In the long term, a separate project should be spawend for ommysql, but I'd like to do that only after the plugin interface is fully stable (what it is not yet). --------------------------------------------------------------------------- Version 1.19.7 (rgerhards), 2007-09-25 - added code to handle situations where senders send us messages ending with a NUL character. It is now simply removed. This also caused trailing LF reduction to fail, when it was followed by such a NUL. This is now also handled. - replaced some non-thread-safe function calls by their thread-safe counterparts - fixed a minor memory leak that occured when the %APPNAME% property was used (I think nobody used that in practice) - fixed a bug that caused signal handlers in cvthname() not to be restored when a malicious pointer record was detected and processing of the message been stopped for that reason (this should be really rare and can not be related to the segfault bug we are hunting). - fixed a bug in cvthname that lead to passing a wrong parameter - in practice, this had no impact. - general code cleanup (e.g. compiler warnings, comments) --------------------------------------------------------------------------- Version 1.19.6 (rgerhards), 2007-09-11 - applied patch by varmojfekoj to change signal handling to the new sigaction API set (replacing the depreciated signal() calls and its friends. - fixed a bug that in --enable-debug mode caused an assertion when the discard action was used - cleaned up compiler warnings - applied patch by varmojfekoj to FIX a bug that could cause segfaults if empty properties were processed using modifying options (e.g. space-cc, drop-cc) - fixed man bug: rsyslogd supports -l option --------------------------------------------------------------------------- Version 1.19.5 (rgerhards), 2007-09-07 - changed part of the CStr interface so that better error tracking is provided and the calling sequence is more intuitive (there were invalid calls based on a too-weired interface) - (hopefully) fixed some remaining bugs rooted in wrong use of the CStr class. These could lead to program abort. - applied patch by varmojfekoj two fix two potential segfault situations - added $ModDir config directive - modified $ModLoad so that an absolute path may be specified as module name (e.g. /rsyslog/ommysql.so) --------------------------------------------------------------------------- Version 1.19.4 (rgerhards/varmojfekoj), 2007-09-04 - fixed a number of small memory leaks - thanks varmojfekoj for patching - fixed an issue with CString class that could lead to rsyslog abort in tplToString() - thanks varmojfekoj for patching - added a man-version of the config file documenation - thanks to Michel Samia for providing the man file - fixed bug: a template like this causes an infinite loop: $template opts,"%programname:::a,b%" thanks varmojfekoj for the patch - fixed bug: case changing options crash freeing the string pointer because they modify it: $template opts2,"%programname::1:lowercase%" thanks varmojfekoj for the patch --------------------------------------------------------------------------- Version 1.19.3 (mmeckelein/varmojfekoj), 2007-08-31 - small mem leak fixed (after calling parseSelectorAct) - Thx varmojkekoj - documentation section "Regular File" und "Blocks" updated - solved an issue with dynamic file generation - Once again many thanks to varmojfekoj - the negative selector for program name filter (Blocks) does not work as expected - Thanks varmojfekoj for patching - added forwarding information to sysklogd (requires special template) to config doc --------------------------------------------------------------------------- Version 1.19.2 (mmeckelein/varmojfekoj), 2007-08-28 - a specifically formed message caused a segfault - Many thanks varmojfekoj for providing a patch - a typo and a weird condition are fixed in msg.c - Thanks again varmojfekoj - on file creation the file was always owned by root:root. This is fixed now - Thanks ypsa for solving this issue --------------------------------------------------------------------------- Version 1.19.1 (mmeckelein), 2007-08-22 - a bug that caused a high load when a TCP/UDP connection was closed is fixed now - Thanks mildew for solving this issue - fixed a bug which caused a segfault on reinit - Thx varmojfekoj for the patch - changed the hardcoded module path "/lib/rsyslog" to $(pkglibdir) in order to avoid trouble e.g. on 64 bit platforms (/lib64) - many thanks Peter Vrabec and darix, both provided a patch for solving this issue - enhanced the unloading of modules - thanks again varmojfekoj - applied a patch from varmojfekoj which fixes various little things in MySQL output module --------------------------------------------------------------------------- Version 1.19.0 (varmojfekoj/rgerhards), 2007-08-16 - integrated patch from varmojfekoj to make the mysql module a loadable one many thanks for the patch, MUCH appreciated --------------------------------------------------------------------------- Version 1.18.2 (rgerhards), 2007-08-13 - fixed a bug in outchannel code that caused templates to be incorrectly parsed - fixed a bug in ommysql that caused a wrong ";template" missing message - added some code for unloading modules; not yet fully complete (and we do not yet have loadable modules, so this is no problem) - removed debian subdirectory by request of a debian packager (this is a special subdir for debian and there is also no point in maintaining it when there is a debian package available - so I gladly did this) in some cases - improved overall doc quality (some pages were quite old) and linked to more of the online resources. - improved /contrib/delete_mysql script by adding a host option and some other minor modifications --------------------------------------------------------------------------- Version 1.18.1 (rgerhards), 2007-08-08 - applied a patch from varmojfekoj which solved a potential segfault of rsyslogd on HUP - applied patch from Michel Samia to fix compilation when the pthreads feature is disabled - some code cleanup (moved action object to its own file set) - add config directive $MainMsgQueueSize, which now allows to configure the queue size dynamically - all compile-time settings are now shown in rsyslogd -v, not just the active ones - enhanced performance a little bit more - added config file directive $ActionResumeInterval - fixed a bug that prevented compilation under debian sid - added a contrib directory for user-contributed useful things --------------------------------------------------------------------------- Version 1.18.0 (rgerhards), 2007-08-03 - rsyslog now supports fallback actions when an action did not work. This is a great feature e.g. for backup database servers or backup syslog servers - modified rklogd to only change the console log level if -c is specified - added feature to use multiple actions inside a single selector - implemented $ActionExecOnlyWhenPreviousIsSuspended config directive - error messages during startup are now spit out to the configured log destinations --------------------------------------------------------------------------- Version 1.17.6 (rgerhards), 2007-08-01 - continued to work on output module modularization - basic stage of this work is now FINISHED - fixed bug in OMSRcreate() - always returned SR_RET_OK - fixed a bug that caused ommysql to always complain about missing templates - fixed a mem leak in OMSRdestruct - freeing the object itself was forgotten - thanks to varmojfekoj for the patch - fixed a memory leak in syslogd/init() that happend when the config file could not be read - thanks to varmojfekoj for the patch - fixed insufficient memory allocation in addAction() and its helpers. The initial fix and idea was developed by mildew, I fine-tuned it a bit. Thanks a lot for the fix, I'd probably had pulled out my hair to find the bug... - added output of config file line number when a parsing error occured - fixed bug in objomsr.c that caused program to abort in debug mode with an invalid assertion (in some cases) - fixed a typo that caused the default template for MySQL to be wrong. thanks to mildew for catching this. - added configuration file command $DebugPrintModuleList and $DebugPrintCfSysLineHandlerList - fixed an invalid value for the MARK timer - unfortunately, there was a testing aid left in place. This resulted in quite frequent MARK messages - added $IncludeConfig config directive - applied a patch from mildew to prevent rsyslogd from freezing under heavy load. This could happen when the queue was full. Now, we drop messages but rsyslogd remains active. --------------------------------------------------------------------------- Version 1.17.5 (rgerhards), 2007-07-30 - continued to work on output module modularization - fixed a missing file bug - thanks to Andrea Montanari for reporting this problem - fixed a problem with shutting down the worker thread and freeing the selector_t list - this caused messages to be lost, because the message queue was not properly drained before the selectors got destroyed. --------------------------------------------------------------------------- Version 1.17.4 (rgerhards), 2007-07-27 - continued to work on output module modularization - fixed a situation where rsyslogd could create zombie processes thanks to mildew for the patch - applied patch from Michel Samia to fix compilation when NOT compiled for pthreads --------------------------------------------------------------------------- Version 1.17.3 (rgerhards), 2007-07-25 - continued working on output module modularization - fixed a bug that caused rsyslogd to segfault on exit (and probably also on HUP), when there was an unsent message in a selector that required forwarding and the dns lookup failed for that selector (yes, it was pretty unlikely to happen;)) thanks to varmojfekoj for the patch - fixed a memory leak in config file parsing and die() thanks to varmojfekoj for the patch - rsyslogd now checks on startup if it is capable to performa any work at all. If it cant, it complains and terminates thanks to Michel Samia for providing the patch! - fixed a small memory leak when HUPing syslogd. The allowed sender list now gets freed. thanks to mildew for the patch. - changed the way error messages in early startup are logged. They now do no longer use the syslogd code directly but are rather send to stderr. --------------------------------------------------------------------------- Version 1.17.2 (rgerhards), 2007-07-23 - made the port part of the -r option optional. Needed for backward compatibility with sysklogd - replaced system() calls with something more reasonable. Please note that this might break compatibility with some existing configuration files. We accept this in favour of the gained security. - removed a memory leak that could occur if timegenerated was used in RFC 3164 format in templates - did some preparation in msg.c for advanced multithreading - placed the hooks, but not yet any active code - worked further on modularization - added $ModLoad MySQL (dummy) config directive - added DropTrailingLFOnReception config directive --------------------------------------------------------------------------- Version 1.17.1 (rgerhards), 2007-07-20 - fixed a bug that caused make install to install rsyslogd and rklogd under the wrong names - fixed bug that caused $AllowedSenders to handle IPv6 scopes incorrectly; also fixed but that could grabble $AllowedSender wildcards. Thanks to mildew@gmail.com for the patch - minor code cleanup - thanks to Peter Vrabec for the patch - fixed minimal memory leak on HUP (caused by templates) thanks to varmojfekoj for the patch - fixed another memory leak on HUPing and on exiting rsyslogd again thanks to varmojfekoj for the patch - code cleanup (removed compiler warnings) - fixed portability bug in configure.ac - thanks to Bartosz Kuźma for patch - moved msg object into its own file set - added the capability to continue trying to write log files when the file system is full. Functionality based on patch by Martin Schulze to sysklogd package. --------------------------------------------------------------------------- Version 1.17.0 (RGer), 2007-07-17 - added $RepeatedLineReduction config parameter - added $EscapeControlCharactersOnReceive config parameter - added $ControlCharacterEscapePrefix config parameter - added $DirCreateMode config parameter - added $CreateDirs config parameter - added $DebugPrintTemplateList config parameter - added $ResetConfigVariables config parameter - added $FileOwner config parameter - added $FileGroup config parameter - added $DirOwner config parameter - added $DirGroup config parameter - added $FailOnChownFailure config parameter - added regular expression support to the filter engine thanks to Michel Samia for providing the patch! - enhanced $AllowedSender functionality. Credits to mildew@gmail.com for the patch doing that - added IPv6 support - allowed DNS hostnames - allowed DNS wildcard names - added new option $DropMsgsWithMaliciousDnsPTRRecords - added autoconf so that rfc3195d, rsyslogd and klogd are stored to /sbin - added capability to auto-create directories with dynaFiles --------------------------------------------------------------------------- Version 1.16.0 (RGer/Peter Vrabec), 2007-07-13 - The Friday, 13th Release ;) - build system switched to autotools - removed SYSV preprocessor macro use, replaced with autotools equivalents - fixed a bug that caused rsyslogd to segfault when TCP listening was disabled and it terminated - added new properties "syslogfacility-text" and "syslogseverity-text" thanks to varmojfekoj for the patch - added the -x option to disable hostname dns reslution thanks to varmojfekoj for the patch - begun to better modularize syslogd.c - this is an ongoing project; moved type definitions to a separate file - removed some now-unused fields from struct filed - move file size limit fields in struct field to the "right spot" (the file writing part of the union - f_un.f_file) - subdirectories linux and solaris are no longer part of the distribution package. This is not because we cease support for them, but there are no longer any files in them after the move to autotools --------------------------------------------------------------------------- Version 1.15.1 (RGer), 2007-07-10 - fixed a bug that caused a dynaFile selector to stall when there was an open error with one file - improved template processing for dynaFiles; templates are now only looked up during initialization - speeds up processing - optimized memory layout in struct filed when compiled with MySQL support - fixed a bug that caused compilation without SYSLOG_INET to fail - re-enabled the "last message repeated n times" feature. This feature was not taken care of while rsyslogd evolved from sysklogd and it was more or less defunct. Now it is fully functional again. - added system properties: $NOW, $YEAR, $MONTH, $DAY, $HOUR, $MINUTE - fixed a bug in iovAsString() that caused a memory leak under stress conditions (most probably memory shortage). This was unlikely to ever happen, but it doesn't hurt doing it right - cosmetic: defined type "uchar", change all unsigned chars to uchar --------------------------------------------------------------------------- Version 1.15.0 (RGer), 2007-07-05 - added ability to dynamically generate file names based on templates and thus properties. This was a much-requested feature. It makes life easy when it e.g. comes to splitting files based on the sender address. - added $umask and $FileCreateMode config file directives - applied a patch from Bartosz Kuzma to compile cleanly under NetBSD - checks for extra (unexpected) characters in system config file lines have been added - added IPv6 documentation - was accidently missing from CVS - begun to change char to unsigned char --------------------------------------------------------------------------- Version 1.14.2 (RGer), 2007-07-03 ** this release fixes all known nits with IPv6 ** - restored capability to do /etc/service lookup for "syslog" service when -r 0 was given - documented IPv6 handling of syslog messages - integrate patch from Bartosz Kuźma to make rsyslog compile under Solaris again (the patch replaced a strndup() call, which is not available under Solaris - improved debug logging when waiting on select - updated rsyslogd man page with new options (-46A) --------------------------------------------------------------------------- Version 1.14.1 (RGer/Peter Vrabec), 2007-06-29 - added Peter Vrabec's patch for IPv6 TCP - prefixed all messages send to stderr in rsyslogd with "rsyslogd: " --------------------------------------------------------------------------- Version 1.14.0 (RGer/Peter Vrabec), 2007-06-28 - Peter Vrabec provided IPv6 for rsyslog, so we are now IPv6 enabled IPv6 Support is currently for UDP only, TCP is to come soon. AllowedSender configuration does not yet work for IPv6. - fixed code in iovCreate() that broke C's strict aliasing rules - fixed some char/unsigned char differences that forced the compiler to spit out warning messages - updated the Red Hat init script to fix a known issue (thanks to Peter Vrabec) --------------------------------------------------------------------------- Version 1.13.5 (RGer), 2007-06-22 - made the TCP session limit configurable via command line switch now -t , - added man page for rklogd(8) (basically a copy from klogd, but now there is one...) - fixed a bug that caused internal messages (e.g. rsyslogd startup) to appear without a tag. - removed a minor memory leak that occurred when TAG processing requalified a HOSTNAME to be a TAG (and a TAG already was set). - removed potential small memory leaks in MsgSet***() functions. There would be a leak if a property was re-set, something that happened extremely seldom. --------------------------------------------------------------------------- Version 1.13.4 (RGer), 2007-06-18 - added a new property "PRI-text", which holds the PRI field in textual form (e.g. "syslog.info") - added alias "syslogseverity" for "syslogpriority", which is a misleading property name that needs to stay for historical reasons (and backward-compatility) - added doc on how to record PRI value in log file - enhanced signal handling in klogd, including removal of an unsafe call to the logging system during signal handling --------------------------------------------------------------------------- Version 1.13.3 (RGer), 2007-06-15 - create a version of syslog.c from scratch. This is now - highly optimized for rsyslog - removes an incompatible license problem as the original version had a BSD license with advertising clause - fixed in the regard that rklogd will continue to work when rsysogd has been restarted (the original version, as well as sysklogd, will remain silent then) - solved an issue with an extra NUL char at message end that the original version had - applied some changes to klogd to care for the new interface - fixed a bug in syslogd.c which prevented compiling under debian --------------------------------------------------------------------------- Version 1.13.2 (RGer), 2007-06-13 - lib order in makefile patched to facilitate static linking - thanks to Bennett Todd for providing the patch - Integrated a patch from Peter Vrabec (pvrabec@redheat.com): - added klogd under the name of rklogd (remove dependency on original sysklogd package - createDB.sql now in UTF - added additional config files for use on Red Hat --------------------------------------------------------------------------- Version 1.13.1 (RGer), 2007-02-05 - changed the listen backlog limit to a more reasonable value based on the maximum number of TCP connections configurd (10% + 5) - thanks to Guy Standen for the hint (actually, the limit was 5 and that was a left-over from early testing). - fixed a bug in makefile which caused DB-support to be disabled when NETZIP support was enabled - added the -e option to allow transmission of every message to remote hosts (effectively turns off duplicate message suppression) - (somewhat) improved memory consumption when compiled with MySQL support - looks like we fixed an incompatibility with MySQL 5.x and above software At least in one case, the remote server name was destroyed, leading to a connection failure. The new, improved code does not have this issue and so we see this as solved (the new code is generally somewhat better, so there is a good chance we fixed this incompatibility). --------------------------------------------------------------------------- Version 1.13.0 (RGer), 2006-12-19 - added '$' as ToPos proptery replacer specifier - means "up to the end of the string" - property replacer option "escape-cc", "drop-cc" and "space-cc" added - changed the handling of \0 characters inside syslog messages. We now consistently escape them to "#000". This is somewhat recommended in the draft-ietf-syslog-protocol-19 draft. While the real recomendation is to not escape any characters at all, we can not do this without considerable modification of the code. So we escape it to "#000", which is consistent with a sample found in the Internet-draft. - removed message glue logic (see printchopped() comment for details) Also caused removal of parts table and thus some improvements in memory usage. - changed the default MAXLINE to 2048 to take care of recent syslog standardization efforts (can easily be changed in syslogd.c) - added support for byte-counted TCP syslog messages (much like syslog-transport-tls-05 Internet Draft). This was necessary to support compression over TCP. - added support for receiving compressed syslog messages - added support for sending compressed syslog messages - fixed a bug where the last message in a syslog/tcp stream was lost if it was not properly terminated by a LF character --------------------------------------------------------------------------- Version 1.12.3 (RGer), 2006-10-04 - implemented some changes to support Solaris (but support is not yet complete) - commented out (via #if 0) some methods that are currently not being use but should be kept for further us - added (interim) -u 1 option to turn off hostname and tag parsing - done some modifications to better support Fedora - made the field delimiter inside property replace configurable via template - fixed a bug in property replacer: if fields were used, the delimitor became part of the field. Up until now, this was barely noticable as the delimiter as TAB only and thus invisible to a human. With other delimiters available now, it quickly showed up. This bug fix might cause some grief to existing installations if they used the extra TAB for whatever reasons - sorry folks... Anyhow, a solution is easy: just add a TAB character contstant into your template. Thus, there has no attempt been made to do this in a backwards-compatible way. --------------------------------------------------------------------------- Version 1.12.2 (RGer), 2006-02-15 - fixed a bug in the RFC 3339 date formatter. An extra space was added after the actual timestamp - added support for providing high-precision RFC3339 timestamps for (rsyslogd-)internally-generated messages - very (!) experimental support for syslog-protocol internet draft added (the draft is experimental, the code is solid ;)) - added support for field-extracting in the property replacer - enhanced the legacy-syslog parser so that it can interpret messages that do not contain a TIMESTAMP - fixed a bug that caused the default socket (usually /dev/log) to be opened even when -o command line option was given - fixed a bug in the Debian sample startup script - it caused rsyslogd to listen to remote requests, which it shouldn't by default --------------------------------------------------------------------------- Version 1.12.1 (RGer), 2005-11-23 - made multithreading work with BSD. Some signal-handling needed to be restructured. Also, there might be a slight delay of up to 10 seconds when huping and terminating rsyslogd under BSD - fixed a bug where a NULL-pointer was passed to printf() in logmsg(). - fixed a bug during "make install" where rc3195d was not installed Thanks to Bennett Todd for spotting this. - fixed a bug where rsyslogd dumped core when no TAG was found in the received message - enhanced message parser so that it can deal with missing hostnames in many cases (may not be totally fail-safe) - fixed a bug where internally-generated messages did not have the correct TAG --------------------------------------------------------------------------- Version 1.12.0 (RGer), 2005-10-26 - moved to a multi-threaded design. single-threading is still optionally available. Multi-threading is experimental! - fixed a potential race condition. In the original code, marking was done by an alarm handler, which could lead to all sorts of bad things. This has been changed now. See comments in syslogd.c/domark() for details. - improved debug output for property-based filters - not a code change, but: I have checked all exit()s to make sure that none occurs once rsyslogd has started up. Even in unusual conditions (like low-memory conditions) rsyslogd somehow remains active. Of course, it might loose a message or two, but at least it does not abort and it can also recover when the condition no longer persists. - fixed a bug that could cause loss of the last message received immediately before rsyslogd was terminated. - added comments on thread-safety of global variables in syslogd.c - fixed a small bug: spurios printf() when TCP syslog was used - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug with regular expression support (thanks to Andres Riancho) - a little bit of code restructuring (especially main(), which was horribly large) --------------------------------------------------------------------------- Version 1.11.1 (RGer), 2005-10-19 - support for BSD-style program name and host blocks - added a new property "programname" that can be used in templates - added ability to specify listen port for rfc3195d - fixed a bug that rendered the "startswith" comparison operation unusable. - changed more functions to "static" storage class to help compiler optimize (should have been static in the first place...) - fixed a potential memory leak in the string buffer class destructor. As the destructur was previously never called, the leak did not actually appear. - some internal restructuring in anticipation/preparation of minimal multi-threading support - rsyslogd still shares some code with the sysklogd project. Some patches for this shared code have been brought over from the sysklogd CVS. --------------------------------------------------------------------------- Version 1.11.0 (RGer), 2005-10-12 - support for receiving messages via RFC 3195; added rfc3195d for that purpose - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases --------------------------------------------------------------------------- Version 1.10.2 (RGer), 2005-09-27 - added comparison operations in property-based filters: * isequal * startswith - added ability to negate all property-based filter comparison operations by adding a !-sign right in front of the operation name - added the ability to specify remote senders for UDP and TCP received messages. Allows to block all but well-known hosts - changed the $-config line directives to be case-INsensitive - new command line option -w added: "do not display warnings if messages from disallowed senders are received" - fixed a bug that caused rsyslogd to dump core when the compare value was not quoted in property-based filters - fixed a bug in the new CStr compare function which lead to invalid results (fortunately, this function was not yet used widely) - added better support for "debugging" rsyslog.conf property filters (only if -d switch is given) - changed some function definitions to static, which eventually enables some compiler optimizations - fixed a bug in MySQL code; when a SQL error occured, rsyslogd could run in a tight loop. This was due to invalid sequence of error reporting and is now fixed. --------------------------------------------------------------------------- Version 1.10.1 (RGer), 2005-09-23 - added the ability to execute a shell script as an action. Thanks to Bjoern Kalkbrenner for providing the code! - fixed a bug in the MySQL code; due to the bug the automatic one-time retry after an error did not happen - this lead to error message in cases where none should be seen (e.g. after a MySQL restart) - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.10.0 (RGer), 2005-09-20 REMINDER: 1.10 is the first unstable version if the 1.x series! - added the capability to filter on any property in selector lines (not just facility and priority) - changed stringbuf into a new counted string class - added support for a "discard" action. If a selector line with discard (~ character) is found, no selector lines *after* that line will be processed. - thanks to Andres Riancho, regular expression support has been added to the template engine - added the FROMHOST property in the template processor, which could previously not be obtained. Thanks to Cristian Testa for pointing this out and even providing a fix. - added display of compile-time options to -v output - performance improvement for production build - made some checks to happen only during debug mode - fixed a problem with compiling on SUSE and - while doing so - removed the socket call to set SO_BSDCOMPAT in cases where it is obsolete. --------------------------------------------------------------------------- Version 1.0.4 (RGer), 2006-02-01 - a small but important fix: the tcp receiver had two forgotten printf's in it that caused a lot of unnecessary output to stdout. This was important enough to justify a new release --------------------------------------------------------------------------- Version 1.0.3 (RGer), 2005-11-14 - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases - applied some patches available from the sysklogd project to code shared from there - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug in the TCP sender that caused the retry logic to fail after an error or receiver overrun - fixed a bug in init() that could lead to dumping core - fixed a bug that could lead to dumping core when no HOSTNAME or no TAG was present in the syslog message --------------------------------------------------------------------------- Version 1.0.2 (RGer), 2005-10-05 - fixed an issue with MySQL error reporting. When an error occured, the MySQL driver went into an endless loop (at least in most cases). --------------------------------------------------------------------------- Version 1.0.1 (RGer), 2005-09-23 - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.0.0 (RGer), 2005-09-12 - changed install doc to cover daily cron scripts - a trouble source - added rc script for slackware (provided by Chris Elvidge - thanks!) - fixed a really minor bug in usage() - the -r option was still reported as without the port parameter --------------------------------------------------------------------------- Version 0.9.8 (RGer), 2005-09-05 - made startup and shutdown message more consistent and included the pid, so that they can be easier correlated. Used syslog-protocol structured data format for this purpose. - improved config info in startup message, now tells not only if it is listening remote on udp, but also for tcp. Also includes the port numbers. The previous startup message was misleading, because it did not say "remote reception" if rsyslogd was only listening via tcp (but not via udp). - added a "how can you help" document to the doc set --------------------------------------------------------------------------- Version 0.9.7 (RGer), 2005-08-15 - some of the previous doc files (like INSTALL) did not properly reflect the changes to the build process and the new doc. Fixed that. - changed syslogd.c so that when compiled without database support, an error message is displayed when a database action is detected in the config file (previously this was used as an user rule ;)) - fixed a bug in the os-specific Makefiles which caused MySQL support to not be compiled, even if selected --------------------------------------------------------------------------- Version 0.9.6 (RGer), 2005-08-09 - greatly enhanced documentation. Now available in html format in the "doc" folder and FreeBSD. Finally includes an install howto. - improved MySQL error messages a little - they now show up as log messages, too (formerly only in debug mode) - added the ability to specify the listen port for udp syslog. WARNING: This introduces an incompatibility. Formerly, udp syslog was enabled by the -r command line option. Now, it is "-r [port]", which is consistent with the tcp listener. However, just -r will now return an error message. - added sample startup scripts for Debian and FreeBSD - added support for easy feature selection in the makefile. Un- fortunately, this also means I needed to spilt the make file for different OS and distros. There are some really bad syntax differences between FreeBSD and Linux make. --------------------------------------------------------------------------- Version 0.9.5 (RGer), 2005-08-01 - the "semicolon bug" was actually not (fully) solved in 0.9.4. One part of the bug was solved, but another still existed. This one is fixed now, too. - the "semicolon bug" actually turned out to be a more generic bug. It appeared whenever an invalid template name was given. With some selector actions, rsyslogd dumped core, with other it "just" had a small ressource leak with others all worked well. These anomalies are now fixed. Note that they only appeared during system initaliziation once the system was running, nothing bad happened. - improved error reporting for template errors on startup. They are now shown on the console and the start-up tty. Formerly, they were only visible in debug mode. - support for multiple instances of rsyslogd on a single machine added - added new option "-o" --> omit local unix domain socket. This option enables rsyslogd NOT to listen to the local socket. This is most helpful when multiple instances of rsyslogd (or rsyslogd and another syslogd) shall run on a single system. - added new option "-i " which allows to specify the pidfile. This is needed when multiple instances of rsyslogd are to be run. - the new project home page is now online at www.rsyslog.com --------------------------------------------------------------------------- Version 0.9.4 (RGer), 2005-07-25 - finally added the TCP sender. It now supports non-blocking mode, no longer disabling message reception during connect. As it is now, it is usable in production. The code could be more sophisticated, but I've kept it short in anticipation of the move to liblogging, which will lead to the removal of the code just written ;) - the "exiting on signal..." message still had the "syslogd" name in it. Changed this to "rsyslogd", as we do not have a large user base yet, this should pose no problem. - fixed "the semiconlon" bug. rsyslogd dumped core if a write-db action was specified but no semicolon was given after the password (an empty template was ok, but the semicolon needed to be present). - changed a default for traditional output format. During testing, it was seen that the timestamp written to file in default format was the time of message reception, not the time specified in the TIMESTAMP field of the message itself. Traditionally, the message TIMESTAMP is used and this has been changed now. --------------------------------------------------------------------------- Version 0.9.3 (RGer), 2005-07-19 - fixed a bug in the message parser. In June, the RFC 3164 timestamp was not correctly parsed (yes, only in June and some other months, see the code comment to learn why...) - added the ability to specify the destination port when forwarding syslog messages (both for TCP and UDP) - added an very experimental TCP sender (activated by @@machine:port in config). This is not yet for production use. If the receiver is not alive, rsyslogd will wait quite some time until the connection request times out, which most probably leads to loss of incoming messages. --------------------------------------------------------------------------- Version 0.9.2 (RGer), around 2005-07-06 - I intended to change the maxsupported message size to 32k to support IHE - but given the memory inefficiency in the usual use cases, I have not done this. I have, however, included very specific instructions on how to do this in the source code. I have also done some testing with 32k messages, so you can change the max size without taking too much risk. - added a syslog/tcp receiver; we now can receive messages via plain tcp, but we can still send only via UDP. The syslog/tcp receiver is the primary enhancement of this release. - slightly changed some error messages that contained a spurios \n at the end of the line (which gives empty lines in your log...) --------------------------------------------------------------------------- Version 0.9.1 (RGer) - fixed code so that it compiles without errors under FreeBSD - removed now unused function "allocate_log()" from syslogd.c - changed the make file so that it contains more defines for different environments (in the long term, we need a better system for disabling/enabling features...) - changed some printf's printing off_t types to %lld and explicit (long long) casts. I tried to figure out the exact type, but did not succeed in this. In the worst case, ultra-large peta- byte files will now display funny informational messages on rollover, something I think we can live with for the neersion 3.11.2 (rgerhards), 2008-02-?? --------------------------------------------------------------------------- Version 3.11.1 (rgerhards), 2008-02-12 - SNMP trap sender added thanks to Andre Lorbach (omsnmp) - added input-plugin interface specification in form of a (copy) template input module - applied documentation fix by Michael Biebl -- many thanks! - bugfix: immark did not have MARK flags set... - added x-info field to rsyslogd startup/shutdown message. Hopefully points users to right location for further info (many don't even know they run rsyslog ;)) - bugfix: trailing ":" of tag was lost while parsing legacy syslog messages without timestamp - thanks to Anders Blomdell for providing a patch! - fixed a bug in stringbuf.c related to STRINGBUF_TRIM_ALLOCSIZE, which wasn't supposed to be used with rsyslog. Put a warning message up that tells this feature is not tested and probably not worth the effort. Thanks to Anders Blomdell fro bringing this to our attention - somewhat improved performance of string buffers - fixed bug that caused invalid treatment of tabs (HT) in rsyslog.conf - bugfix: setting for $EscapeCopntrolCharactersOnReceive was not properly initialized - clarified usage of space-cc property replacer option - improved abort diagnostic handler - some initial effort for malloc/free runtime debugging support - bugfix: using dynafile actions caused rsyslogd abort - fixed minor man errors thanks to Michael Biebl --------------------------------------------------------------------------- Version 3.11.0 (rgerhards), 2008-01-31 - implemented queued actions - implemented simple rate limiting for actions - implemented deliberate discarding of lower priority messages over higher priority ones when a queue runs out of space - implemented disk quotas for disk queues - implemented the $ActionResumeRetryCount config directive - added $ActionQueueFilename config directive - added $ActionQueueSize config directive - added $ActionQueueHighWaterMark config directive - added $ActionQueueLowWaterMark config directive - added $ActionQueueDiscardMark config directive - added $ActionQueueDiscardSeverity config directive - added $ActionQueueCheckpointInterval config directive - added $ActionQueueType config directive - added $ActionQueueWorkerThreads config directive - added $ActionQueueTimeoutshutdown config directive - added $ActionQueueTimeoutActionCompletion config directive - added $ActionQueueTimeoutenQueue config directive - added $ActionQueueTimeoutworkerThreadShutdown config directive - added $ActionQueueWorkerThreadMinimumMessages config directive - added $ActionQueueMaxFileSize config directive - added $ActionQueueSaveonShutdown config directive - addded $ActionQueueDequeueSlowdown config directive - addded $MainMsgQueueDequeueSlowdown config directive - bugfix: added forgotten docs to package - improved debugging support - fixed a bug that caused $MainMsgQueueCheckpointInterval to work incorrectly - when a long-running action needs to be cancelled on shutdown, the message that was processed by it is now preserved. This finishes support for guaranteed delivery of messages (if the output supports it, of course) - fixed bug in output module interface, see http://sourceforge.net/tracker/index.php?func=detail&aid=1881008&group_id=123448&atid=696552 - changed the ommysql output plugin so that the (lengthy) connection initialization now takes place in message processing. This works much better with the new queued action mode (fast startup) - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! - bugfixed stream class offset handling on 32bit platforms --------------------------------------------------------------------------- Version 3.10.3 (rgerhards), 2008-01-28 - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - run-time instrumentation added - implemented disk-assisted queue mode, which enables on-demand disk spooling if the queue's in-memory queue is exhausted - implemented a dynamic worker thread pool for processing incoming messages; workers are started and shut down as need arises - implemented a run-time instrumentation debug package - implemented the $MainMsgQueueSaveOnShutdown config directive - implemented the $MainMsgQueueWorkerThreadMinimumMessages config directive - implemented the $MainMsgQueueTimeoutWorkerThreadShutdown config directive --------------------------------------------------------------------------- Version 3.10.2 (rgerhards), 2008-01-14 - added the ability to keep stop rsyslogd without the need to drain the main message queue. In disk queue mode, rsyslog continues to run from the point where it stopped. In case of a system failure, it continues to process messages from the last checkpoint. - fixed a bug that caused a segfault on startup when no $WorkDir directive was specified in rsyslog.conf - provided more fine-grain control over shutdown timeouts and added a way to specify the enqueue timeout when the main message queue is full - implemented $MainMsgQueueCheckpointInterval config directive - implemented $MainMsgQueueTimeoutActionCompletion config directive - implemented $MainMsgQueueTimeoutEnqueue config directive - implemented $MainMsgQueueTimeoutShutdown config directive --------------------------------------------------------------------------- Version 3.10.1 (rgerhards), 2008-01-10 - implemented the "disk" queue mode. However, it currently is of very limited use, because it does not support persistence over rsyslogd runs. So when rsyslogd is stopped, the queue is drained just as with the in-memory queue modes. Persistent queues will be a feature of the next release. - performance-optimized string class, should bring an overall improvement - fixed a memory leak in imudp -- thanks to varmojfekoj for the patch - fixed a race condition that could lead to a rsyslogd hang when during HUP or termination - done some doc updates - added $WorkDirectory config directive - added $MainMsgQueueFileName config directive - added $MainMsgQueueMaxFileSize config directive --------------------------------------------------------------------------- Version 3.10.0 (rgerhards), 2008-01-07 - implemented input module interface and initial input modules - enhanced threading for input modules (each on its own thread now) - ability to bind UDP listeners to specific local interfaces/ports and ability to run multiple of them concurrently - added ability to specify listen IP address for UDP syslog server - license changed to GPLv3 - mark messages are now provided by loadble module immark - rklogd is no longer provided. Its functionality has now been taken over by imklog, a loadable input module. This offers a much better integration into rsyslogd and makes sure that the kernel logger process is brought up and down at the appropriate times - enhanced $IncludeConfig directive to support wildcard characters (thanks to Michael Biebl) - all inputs are now implemented as loadable plugins - enhanced threading model: each input module now runs on its own thread - enhanced message queue which now supports different queueing methods (among others, this can be used for performance fine-tuning) - added a large number of new configuration directives for the new input modules - enhanced multi-threading utilizing a worker thread pool for the main message queue - compilation without pthreads is no longer supported - much cleaner code due to new objects and removal of single-threading mode --------------------------------------------------------------------------- Version 2.0.1 STABLE (rgerhards), 2008-01-24 - fixed a bug in integer conversion - but this function was never called, so it is not really a useful bug fix ;) - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! --------------------------------------------------------------------------- Version 2.0.0 STABLE (rgerhards), 2008-01-02 - re-release of 1.21.2 as STABLE with no modifications except some doc updates --------------------------------------------------------------------------- Version 1.21.2 (rgerhards), 2007-12-28 - created a gss-api output module. This keeps GSS-API code and TCP/UDP code separated. It is also important for forward- compatibility with v3. Please note that this change breaks compatibility with config files created for 1.21.0 and 1.21.1 - this was considered acceptable. - fixed an error in forwarding retry code (could lead to message corruption but surfaced very seldom) - increased portability for older platforms (AI_NUMERICSERV moved) - removed socket leak in omfwd.c - cross-platform patch for GSS-API compile problem on some platforms thanks to darix for the patch! --------------------------------------------------------------------------- Version 1.21.1 (rgerhards), 2007-12-23 - small doc fix for $IncludeConfig - fixed a bug in llDestroy() - bugfix: fixing memory leak when message queue is full and during parsing. Thanks to varmojfekoj for the patch. - bugfix: when compiled without network support, unix sockets were not properply closed - bugfix: memory leak in cfsysline.c/doGetWord() fixed --------------------------------------------------------------------------- Version 1.21.0 (rgerhards), 2007-12-19 - GSS-API support for syslog/TCP connections was added. Thanks to varmojfekoj for providing the patch with this functionality - code cleanup - enhanced $IncludeConfig directive to support wildcard filenames - changed some multithreading synchronization --------------------------------------------------------------------------- Version 1.20.1 (rgerhards), 2007-12-12 - corrected a debug setting that survived release. Caused TCP connections to be retried unnecessarily often. - When a hostname ACL was provided and DNS resolution for that name failed, ACL processing was stopped at that point. Thanks to mildew for the patch. Fedora Bugzilla: http://bugzilla.redhat.com/show_bug.cgi?id=395911 - fixed a potential race condition, see link for details: http://rgerhards.blogspot.com/2007/12/rsyslog-race-condition.html Note that the probability of problems from this bug was very remote - fixed a memory leak that happend when PostgreSQL date formats were used --------------------------------------------------------------------------- Version 1.20.0 (rgerhards), 2007-12-07 - an output module for postgres databases has been added. Thanks to sur5r for contributing this code - unloading dynamic modules has been cleaned up, we now have a real implementation and not just a dummy "good enough for the time being". - enhanced platform independence - thanks to Bartosz Kuzma and Michael Biebl for their very useful contributions - some general code cleanup (including warnings on 64 platforms, only) --------------------------------------------------------------------------- Version 1.19.12 (rgerhards), 2007-12-03 - cleaned up the build system (thanks to Michael Biebl for the patch) - fixed a bug where ommysql was still not compiled with -pthread option --------------------------------------------------------------------------- Version 1.19.11 (rgerhards), 2007-11-29 - applied -pthread option to build when building for multi-threading mode hopefully solves an issue with segfaulting --------------------------------------------------------------------------- Version 1.19.10 (rgerhards), 2007-10-19 - introdcued the new ":modulename:" syntax for calling module actions in selector lines; modified ommysql to support it. This is primarily an aid for further modules and a prequisite to actually allow third party modules to be created. - minor fix in slackware startup script, "-r 0" is now "-r0" - updated rsyslogd doc set man page; now in html format - undid creation of a separate thread for the main loop -- this did not turn out to be needed or useful, so reduce complexity once again. - added doc fixes provided by Michael Biebl - thanks --------------------------------------------------------------------------- Version 1.19.9 (rgerhards), 2007-10-12 - now packaging system which again contains all components in a single tarball - modularized main() a bit more, resulting in less complex code - experimentally added an additional thread - will see if that affects the segfault bug we experience on some platforms. Note that this change is scheduled to be removed again later. --------------------------------------------------------------------------- Version 1.19.8 (rgerhards), 2007-09-27 - improved repeated message processing - applied patch provided by varmojfekoj to support building ommysql in its own way (now also resides in a plugin subdirectory); ommysql is now a separate package - fixed a bug in cvthname() that lead to message loss if part of the source hostname would have been dropped - created some support for distributing ommysql together with the main rsyslog package. I need to re-think it in the future, but for the time being the current mode is best. I now simply include one additional tarball for ommysql inside the main distribution. I look forward to user feedback on how this should be done best. In the long term, a separate project should be spawend for ommysql, but I'd like to do that only after the plugin interface is fully stable (what it is not yet). --------------------------------------------------------------------------- Version 1.19.7 (rgerhards), 2007-09-25 - added code to handle situations where senders send us messages ending with a NUL character. It is now simply removed. This also caused trailing LF reduction to fail, when it was followed by such a NUL. This is now also handled. - replaced some non-thread-safe function calls by their thread-safe counterparts - fixed a minor memory leak that occured when the %APPNAME% property was used (I think nobody used that in practice) - fixed a bug that caused signal handlers in cvthname() not to be restored when a malicious pointer record was detected and processing of the message been stopped for that reason (this should be really rare and can not be related to the segfault bug we are hunting). - fixed a bug in cvthname that lead to passing a wrong parameter - in practice, this had no impact. - general code cleanup (e.g. compiler warnings, comments) --------------------------------------------------------------------------- Version 1.19.6 (rgerhards), 2007-09-11 - applied patch by varmojfekoj to change signal handling to the new sigaction API set (replacing the depreciated signal() calls and its friends. - fixed a bug that in --enable-debug mode caused an assertion when the discard action was used - cleaned up compiler warnings - applied patch by varmojfekoj to FIX a bug that could cause segfaults if empty properties were processed using modifying options (e.g. space-cc, drop-cc) - fixed man bug: rsyslogd supports -l option --------------------------------------------------------------------------- Version 1.19.5 (rgerhards), 2007-09-07 - changed part of the CStr interface so that better error tracking is provided and the calling sequence is more intuitive (there were invalid calls based on a too-weired interface) - (hopefully) fixed some remaining bugs rooted in wrong use of the CStr class. These could lead to program abort. - applied patch by varmojfekoj two fix two potential segfault situations - added $ModDir config directive - modified $ModLoad so that an absolute path may be specified as module name (e.g. /rsyslog/ommysql.so) --------------------------------------------------------------------------- Version 1.19.4 (rgerhards/varmojfekoj), 2007-09-04 - fixed a number of small memory leaks - thanks varmojfekoj for patching - fixed an issue with CString class that could lead to rsyslog abort in tplToString() - thanks varmojfekoj for patching - added a man-version of the config file documenation - thanks to Michel Samia for providing the man file - fixed bug: a template like this causes an infinite loop: $template opts,"%programname:::a,b%" thanks varmojfekoj for the patch - fixed bug: case changing options crash freeing the string pointer because they modify it: $template opts2,"%programname::1:lowercase%" thanks varmojfekoj for the patch --------------------------------------------------------------------------- Version 1.19.3 (mmeckelein/varmojfekoj), 2007-08-31 - small mem leak fixed (after calling parseSelectorAct) - Thx varmojkekoj - documentation section "Regular File" und "Blocks" updated - solved an issue with dynamic file generation - Once again many thanks to varmojfekoj - the negative selector for program name filter (Blocks) does not work as expected - Thanks varmojfekoj for patching - added forwarding information to sysklogd (requires special template) to config doc --------------------------------------------------------------------------- Version 1.19.2 (mmeckelein/varmojfekoj), 2007-08-28 - a specifically formed message caused a segfault - Many thanks varmojfekoj for providing a patch - a typo and a weird condition are fixed in msg.c - Thanks again varmojfekoj - on file creation the file was always owned by root:root. This is fixed now - Thanks ypsa for solving this issue --------------------------------------------------------------------------- Version 1.19.1 (mmeckelein), 2007-08-22 - a bug that caused a high load when a TCP/UDP connection was closed is fixed now - Thanks mildew for solving this issue - fixed a bug which caused a segfault on reinit - Thx varmojfekoj for the patch - changed the hardcoded module path "/lib/rsyslog" to $(pkglibdir) in order to avoid trouble e.g. on 64 bit platforms (/lib64) - many thanks Peter Vrabec and darix, both provided a patch for solving this issue - enhanced the unloading of modules - thanks again varmojfekoj - applied a patch from varmojfekoj which fixes various little things in MySQL output module --------------------------------------------------------------------------- Version 1.19.0 (varmojfekoj/rgerhards), 2007-08-16 - integrated patch from varmojfekoj to make the mysql module a loadable one many thanks for the patch, MUCH appreciated --------------------------------------------------------------------------- Version 1.18.2 (rgerhards), 2007-08-13 - fixed a bug in outchannel code that caused templates to be incorrectly parsed - fixed a bug in ommysql that caused a wrong ";template" missing message - added some code for unloading modules; not yet fully complete (and we do not yet have loadable modules, so this is no problem) - removed debian subdirectory by request of a debian packager (this is a special subdir for debian and there is also no point in maintaining it when there is a debian package available - so I gladly did this) in some cases - improved overall doc quality (some pages were quite old) and linked to more of the online resources. - improved /contrib/delete_mysql script by adding a host option and some other minor modifications --------------------------------------------------------------------------- Version 1.18.1 (rgerhards), 2007-08-08 - applied a patch from varmojfekoj which solved a potential segfault of rsyslogd on HUP - applied patch from Michel Samia to fix compilation when the pthreads feature is disabled - some code cleanup (moved action object to its own file set) - add config directive $MainMsgQueueSize, which now allows to configure the queue size dynamically - all compile-time settings are now shown in rsyslogd -v, not just the active ones - enhanced performance a little bit more - added config file directive $ActionResumeInterval - fixed a bug that prevented compilation under debian sid - added a contrib directory for user-contributed useful things --------------------------------------------------------------------------- Version 1.18.0 (rgerhards), 2007-08-03 - rsyslog now supports fallback actions when an action did not work. This is a great feature e.g. for backup database servers or backup syslog servers - modified rklogd to only change the console log level if -c is specified - added feature to use multiple actions inside a single selector - implemented $ActionExecOnlyWhenPreviousIsSuspended config directive - error messages during startup are now spit out to the configured log destinations --------------------------------------------------------------------------- Version 1.17.6 (rgerhards), 2007-08-01 - continued to work on output module modularization - basic stage of this work is now FINISHED - fixed bug in OMSRcreate() - always returned SR_RET_OK - fixed a bug that caused ommysql to always complain about missing templates - fixed a mem leak in OMSRdestruct - freeing the object itself was forgotten - thanks to varmojfekoj for the patch - fixed a memory leak in syslogd/init() that happend when the config file could not be read - thanks to varmojfekoj for the patch - fixed insufficient memory allocation in addAction() and its helpers. The initial fix and idea was developed by mildew, I fine-tuned it a bit. Thanks a lot for the fix, I'd probably had pulled out my hair to find the bug... - added output of config file line number when a parsing error occured - fixed bug in objomsr.c that caused program to abort in debug mode with an invalid assertion (in some cases) - fixed a typo that caused the default template for MySQL to be wrong. thanks to mildew for catching this. - added configuration file command $DebugPrintModuleList and $DebugPrintCfSysLineHandlerList - fixed an invalid value for the MARK timer - unfortunately, there was a testing aid left in place. This resulted in quite frequent MARK messages - added $IncludeConfig config directive - applied a patch from mildew to prevent rsyslogd from freezing under heavy load. This could happen when the queue was full. Now, we drop messages but rsyslogd remains active. --------------------------------------------------------------------------- Version 1.17.5 (rgerhards), 2007-07-30 - continued to work on output module modularization - fixed a missing file bug - thanks to Andrea Montanari for reporting this problem - fixed a problem with shutting down the worker thread and freeing the selector_t list - this caused messages to be lost, because the message queue was not properly drained before the selectors got destroyed. --------------------------------------------------------------------------- Version 1.17.4 (rgerhards), 2007-07-27 - continued to work on output module modularization - fixed a situation where rsyslogd could create zombie processes thanks to mildew for the patch - applied patch from Michel Samia to fix compilation when NOT compiled for pthreads --------------------------------------------------------------------------- Version 1.17.3 (rgerhards), 2007-07-25 - continued working on output module modularization - fixed a bug that caused rsyslogd to segfault on exit (and probably also on HUP), when there was an unsent message in a selector that required forwarding and the dns lookup failed for that selector (yes, it was pretty unlikely to happen;)) thanks to varmojfekoj for the patch - fixed a memory leak in config file parsing and die() thanks to varmojfekoj for the patch - rsyslogd now checks on startup if it is capable to performa any work at all. If it cant, it complains and terminates thanks to Michel Samia for providing the patch! - fixed a small memory leak when HUPing syslogd. The allowed sender list now gets freed. thanks to mildew for the patch. - changed the way error messages in early startup are logged. They now do no longer use the syslogd code directly but are rather send to stderr. --------------------------------------------------------------------------- Version 1.17.2 (rgerhards), 2007-07-23 - made the port part of the -r option optional. Needed for backward compatibility with sysklogd - replaced system() calls with something more reasonable. Please note that this might break compatibility with some existing configuration files. We accept this in favour of the gained security. - removed a memory leak that could occur if timegenerated was used in RFC 3164 format in templates - did some preparation in msg.c for advanced multithreading - placed the hooks, but not yet any active code - worked further on modularization - added $ModLoad MySQL (dummy) config directive - added DropTrailingLFOnReception config directive --------------------------------------------------------------------------- Version 1.17.1 (rgerhards), 2007-07-20 - fixed a bug that caused make install to install rsyslogd and rklogd under the wrong names - fixed bug that caused $AllowedSenders to handle IPv6 scopes incorrectly; also fixed but that could grabble $AllowedSender wildcards. Thanks to mildew@gmail.com for the patch - minor code cleanup - thanks to Peter Vrabec for the patch - fixed minimal memory leak on HUP (caused by templates) thanks to varmojfekoj for the patch - fixed another memory leak on HUPing and on exiting rsyslogd again thanks to varmojfekoj for the patch - code cleanup (removed compiler warnings) - fixed portability bug in configure.ac - thanks to Bartosz Kuźma for patch - moved msg object into its own file set - added the capability to continue trying to write log files when the file system is full. Functionality based on patch by Martin Schulze to sysklogd package. --------------------------------------------------------------------------- Version 1.17.0 (RGer), 2007-07-17 - added $RepeatedLineReduction config parameter - added $EscapeControlCharactersOnReceive config parameter - added $ControlCharacterEscapePrefix config parameter - added $DirCreateMode config parameter - added $CreateDirs config parameter - added $DebugPrintTemplateList config parameter - added $ResetConfigVariables config parameter - added $FileOwner config parameter - added $FileGroup config parameter - added $DirOwner config parameter - added $DirGroup config parameter - added $FailOnChownFailure config parameter - added regular expression support to the filter engine thanks to Michel Samia for providing the patch! - enhanced $AllowedSender functionality. Credits to mildew@gmail.com for the patch doing that - added IPv6 support - allowed DNS hostnames - allowed DNS wildcard names - added new option $DropMsgsWithMaliciousDnsPTRRecords - added autoconf so that rfc3195d, rsyslogd and klogd are stored to /sbin - added capability to auto-create directories with dynaFiles --------------------------------------------------------------------------- Version 1.16.0 (RGer/Peter Vrabec), 2007-07-13 - The Friday, 13th Release ;) - build system switched to autotools - removed SYSV preprocessor macro use, replaced with autotools equivalents - fixed a bug that caused rsyslogd to segfault when TCP listening was disabled and it terminated - added new properties "syslogfacility-text" and "syslogseverity-text" thanks to varmojfekoj for the patch - added the -x option to disable hostname dns reslution thanks to varmojfekoj for the patch - begun to better modularize syslogd.c - this is an ongoing project; moved type definitions to a separate file - removed some now-unused fields from struct filed - move file size limit fields in struct field to the "right spot" (the file writing part of the union - f_un.f_file) - subdirectories linux and solaris are no longer part of the distribution package. This is not because we cease support for them, but there are no longer any files in them after the move to autotools --------------------------------------------------------------------------- Version 1.15.1 (RGer), 2007-07-10 - fixed a bug that caused a dynaFile selector to stall when there was an open error with one file - improved template processing for dynaFiles; templates are now only looked up during initialization - speeds up processing - optimized memory layout in struct filed when compiled with MySQL support - fixed a bug that caused compilation without SYSLOG_INET to fail - re-enabled the "last message repeated n times" feature. This feature was not taken care of while rsyslogd evolved from sysklogd and it was more or less defunct. Now it is fully functional again. - added system properties: $NOW, $YEAR, $MONTH, $DAY, $HOUR, $MINUTE - fixed a bug in iovAsString() that caused a memory leak under stress conditions (most probably memory shortage). This was unlikely to ever happen, but it doesn't hurt doing it right - cosmetic: defined type "uchar", change all unsigned chars to uchar --------------------------------------------------------------------------- Version 1.15.0 (RGer), 2007-07-05 - added ability to dynamically generate file names based on templates and thus properties. This was a much-requested feature. It makes life easy when it e.g. comes to splitting files based on the sender address. - added $umask and $FileCreateMode config file directives - applied a patch from Bartosz Kuzma to compile cleanly under NetBSD - checks for extra (unexpected) characters in system config file lines have been added - added IPv6 documentation - was accidently missing from CVS - begun to change char to unsigned char --------------------------------------------------------------------------- Version 1.14.2 (RGer), 2007-07-03 ** this release fixes all known nits with IPv6 ** - restored capability to do /etc/service lookup for "syslog" service when -r 0 was given - documented IPv6 handling of syslog messages - integrate patch from Bartosz Kuźma to make rsyslog compile under Solaris again (the patch replaced a strndup() call, which is not available under Solaris - improved debug logging when waiting on select - updated rsyslogd man page with new options (-46A) --------------------------------------------------------------------------- Version 1.14.1 (RGer/Peter Vrabec), 2007-06-29 - added Peter Vrabec's patch for IPv6 TCP - prefixed all messages send to stderr in rsyslogd with "rsyslogd: " --------------------------------------------------------------------------- Version 1.14.0 (RGer/Peter Vrabec), 2007-06-28 - Peter Vrabec provided IPv6 for rsyslog, so we are now IPv6 enabled IPv6 Support is currently for UDP only, TCP is to come soon. AllowedSender configuration does not yet work for IPv6. - fixed code in iovCreate() that broke C's strict aliasing rules - fixed some char/unsigned char differences that forced the compiler to spit out warning messages - updated the Red Hat init script to fix a known issue (thanks to Peter Vrabec) --------------------------------------------------------------------------- Version 1.13.5 (RGer), 2007-06-22 - made the TCP session limit configurable via command line switch now -t , - added man page for rklogd(8) (basically a copy from klogd, but now there is one...) - fixed a bug that caused internal messages (e.g. rsyslogd startup) to appear without a tag. - removed a minor memory leak that occurred when TAG processing requalified a HOSTNAME to be a TAG (and a TAG already was set). - removed potential small memory leaks in MsgSet***() functions. There would be a leak if a property was re-set, something that happened extremely seldom. --------------------------------------------------------------------------- Version 1.13.4 (RGer), 2007-06-18 - added a new property "PRI-text", which holds the PRI field in textual form (e.g. "syslog.info") - added alias "syslogseverity" for "syslogpriority", which is a misleading property name that needs to stay for historical reasons (and backward-compatility) - added doc on how to record PRI value in log file - enhanced signal handling in klogd, including removal of an unsafe call to the logging system during signal handling --------------------------------------------------------------------------- Version 1.13.3 (RGer), 2007-06-15 - create a version of syslog.c from scratch. This is now - highly optimized for rsyslog - removes an incompatible license problem as the original version had a BSD license with advertising clause - fixed in the regard that rklogd will continue to work when rsysogd has been restarted (the original version, as well as sysklogd, will remain silent then) - solved an issue with an extra NUL char at message end that the original version had - applied some changes to klogd to care for the new interface - fixed a bug in syslogd.c which prevented compiling under debian --------------------------------------------------------------------------- Version 1.13.2 (RGer), 2007-06-13 - lib order in makefile patched to facilitate static linking - thanks to Bennett Todd for providing the patch - Integrated a patch from Peter Vrabec (pvrabec@redheat.com): - added klogd under the name of rklogd (remove dependency on original sysklogd package - createDB.sql now in UTF - added additional config files for use on Red Hat --------------------------------------------------------------------------- Version 1.13.1 (RGer), 2007-02-05 - changed the listen backlog limit to a more reasonable value based on the maximum number of TCP connections configurd (10% + 5) - thanks to Guy Standen for the hint (actually, the limit was 5 and that was a left-over from early testing). - fixed a bug in makefile which caused DB-support to be disabled when NETZIP support was enabled - added the -e option to allow transmission of every message to remote hosts (effectively turns off duplicate message suppression) - (somewhat) improved memory consumption when compiled with MySQL support - looks like we fixed an incompatibility with MySQL 5.x and above software At least in one case, the remote server name was destroyed, leading to a connection failure. The new, improved code does not have this issue and so we see this as solved (the new code is generally somewhat better, so there is a good chance we fixed this incompatibility). --------------------------------------------------------------------------- Version 1.13.0 (RGer), 2006-12-19 - added '$' as ToPos proptery replacer specifier - means "up to the end of the string" - property replacer option "escape-cc", "drop-cc" and "space-cc" added - changed the handling of \0 characters inside syslog messages. We now consistently escape them to "#000". This is somewhat recommended in the draft-ietf-syslog-protocol-19 draft. While the real recomendation is to not escape any characters at all, we can not do this without considerable modification of the code. So we escape it to "#000", which is consistent with a sample found in the Internet-draft. - removed message glue logic (see printchopped() comment for details) Also caused removal of parts table and thus some improvements in memory usage. - changed the default MAXLINE to 2048 to take care of recent syslog standardization efforts (can easily be changed in syslogd.c) - added support for byte-counted TCP syslog messages (much like syslog-transport-tls-05 Internet Draft). This was necessary to support compression over TCP. - added support for receiving compressed syslog messages - added support for sending compressed syslog messages - fixed a bug where the last message in a syslog/tcp stream was lost if it was not properly terminated by a LF character --------------------------------------------------------------------------- Version 1.12.3 (RGer), 2006-10-04 - implemented some changes to support Solaris (but support is not yet complete) - commented out (via #if 0) some methods that are currently not being use but should be kept for further us - added (interim) -u 1 option to turn off hostname and tag parsing - done some modifications to better support Fedora - made the field delimiter inside property replace configurable via template - fixed a bug in property replacer: if fields were used, the delimitor became part of the field. Up until now, this was barely noticable as the delimiter as TAB only and thus invisible to a human. With other delimiters available now, it quickly showed up. This bug fix might cause some grief to existing installations if they used the extra TAB for whatever reasons - sorry folks... Anyhow, a solution is easy: just add a TAB character contstant into your template. Thus, there has no attempt been made to do this in a backwards-compatible way. --------------------------------------------------------------------------- Version 1.12.2 (RGer), 2006-02-15 - fixed a bug in the RFC 3339 date formatter. An extra space was added after the actual timestamp - added support for providing high-precision RFC3339 timestamps for (rsyslogd-)internally-generated messages - very (!) experimental support for syslog-protocol internet draft added (the draft is experimental, the code is solid ;)) - added support for field-extracting in the property replacer - enhanced the legacy-syslog parser so that it can interpret messages that do not contain a TIMESTAMP - fixed a bug that caused the default socket (usually /dev/log) to be opened even when -o command line option was given - fixed a bug in the Debian sample startup script - it caused rsyslogd to listen to remote requests, which it shouldn't by default --------------------------------------------------------------------------- Version 1.12.1 (RGer), 2005-11-23 - made multithreading work with BSD. Some signal-handling needed to be restructured. Also, there might be a slight delay of up to 10 seconds when huping and terminating rsyslogd under BSD - fixed a bug where a NULL-pointer was passed to printf() in logmsg(). - fixed a bug during "make install" where rc3195d was not installed Thanks to Bennett Todd for spotting this. - fixed a bug where rsyslogd dumped core when no TAG was found in the received message - enhanced message parser so that it can deal with missing hostnames in many cases (may not be totally fail-safe) - fixed a bug where internally-generated messages did not have the correct TAG --------------------------------------------------------------------------- Version 1.12.0 (RGer), 2005-10-26 - moved to a multi-threaded design. single-threading is still optionally available. Multi-threading is experimental! - fixed a potential race condition. In the original code, marking was done by an alarm handler, which could lead to all sorts of bad things. This has been changed now. See comments in syslogd.c/domark() for details. - improved debug output for property-based filters - not a code change, but: I have checked all exit()s to make sure that none occurs once rsyslogd has started up. Even in unusual conditions (like low-memory conditions) rsyslogd somehow remains active. Of course, it might loose a message or two, but at least it does not abort and it can also recover when the condition no longer persists. - fixed a bug that could cause loss of the last message received immediately before rsyslogd was terminated. - added comments on thread-safety of global variables in syslogd.c - fixed a small bug: spurios printf() when TCP syslog was used - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug with regular expression support (thanks to Andres Riancho) - a little bit of code restructuring (especially main(), which was horribly large) --------------------------------------------------------------------------- Version 1.11.1 (RGer), 2005-10-19 - support for BSD-style program name and host blocks - added a new property "programname" that can be used in templates - added ability to specify listen port for rfc3195d - fixed a bug that rendered the "startswith" comparison operation unusable. - changed more functions to "static" storage class to help compiler optimize (should have been static in the first place...) - fixed a potential memory leak in the string buffer class destructor. As the destructur was previously never called, the leak did not actually appear. - some internal restructuring in anticipation/preparation of minimal multi-threading support - rsyslogd still shares some code with the sysklogd project. Some patches for this shared code have been brought over from the sysklogd CVS. --------------------------------------------------------------------------- Version 1.11.0 (RGer), 2005-10-12 - support for receiving messages via RFC 3195; added rfc3195d for that purpose - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases --------------------------------------------------------------------------- Version 1.10.2 (RGer), 2005-09-27 - added comparison operations in property-based filters: * isequal * startswith - added ability to negate all property-based filter comparison operations by adding a !-sign right in front of the operation name - added the ability to specify remote senders for UDP and TCP received messages. Allows to block all but well-known hosts - changed the $-config line directives to be case-INsensitive - new command line option -w added: "do not display warnings if messages from disallowed senders are received" - fixed a bug that caused rsyslogd to dump core when the compare value was not quoted in property-based filters - fixed a bug in the new CStr compare function which lead to invalid results (fortunately, this function was not yet used widely) - added better support for "debugging" rsyslog.conf property filters (only if -d switch is given) - changed some function definitions to static, which eventually enables some compiler optimizations - fixed a bug in MySQL code; when a SQL error occured, rsyslogd could run in a tight loop. This was due to invalid sequence of error reporting and is now fixed. --------------------------------------------------------------------------- Version 1.10.1 (RGer), 2005-09-23 - added the ability to execute a shell script as an action. Thanks to Bjoern Kalkbrenner for providing the code! - fixed a bug in the MySQL code; due to the bug the automatic one-time retry after an error did not happen - this lead to error message in cases where none should be seen (e.g. after a MySQL restart) - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.10.0 (RGer), 2005-09-20 REMINDER: 1.10 is the first unstable version if the 1.x series! - added the capability to filter on any property in selector lines (not just facility and priority) - changed stringbuf into a new counted string class - added support for a "discard" action. If a selector line with discard (~ character) is found, no selector lines *after* that line will be processed. - thanks to Andres Riancho, regular expression support has been added to the template engine - added the FROMHOST property in the template processor, which could previously not be obtained. Thanks to Cristian Testa for pointing this out and even providing a fix. - added display of compile-time options to -v output - performance improvement for production build - made some checks to happen only during debug mode - fixed a problem with compiling on SUSE and - while doing so - removed the socket call to set SO_BSDCOMPAT in cases where it is obsolete. --------------------------------------------------------------------------- Version 1.0.4 (RGer), 2006-02-01 - a small but important fix: the tcp receiver had two forgotten printf's in it that caused a lot of unnecessary output to stdout. This was important enough to justify a new release --------------------------------------------------------------------------- Version 1.0.3 (RGer), 2005-11-14 - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases - applied some patches available from the sysklogd project to code shared from there - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug in the TCP sender that caused the retry logic to fail after an error or receiver overrun - fixed a bug in init() that could lead to dumping core - fixed a bug that could lead to dumping core when no HOSTNAME or no TAG was present in the syslog message --------------------------------------------------------------------------- Version 1.0.2 (RGer), 2005-10-05 - fixed an issue with MySQL error reporting. When an error occured, the MySQL driver went into an endless loop (at least in most cases). --------------------------------------------------------------------------- Version 1.0.1 (RGer), 2005-09-23 - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.0.0 (RGer), 2005-09-12 - changed install doc to cover daily cron scripts - a trouble source - added rc script for slackware (provided by Chris Elvidge - thanks!) - fixed a really minor bug in usage() - the -r option was still reported as without the port parameter --------------------------------------------------------------------------- Version 0.9.8 (RGer), 2005-09-05 - made startup and shutdown message more consistent and included the pid, so that they can be easier correlated. Used syslog-protocol structured data format for this purpose. - improved config info in startup message, now tells not only if it is listening remote on udp, but also for tcp. Also includes the port numbers. The previous startup message was misleading, because it did not say "remote reception" if rsyslogd was only listening via tcp (but not via udp). - added a "how can you help" document to the doc set --------------------------------------------------------------------------- Version 0.9.7 (RGer), 2005-08-15 - some of the previous doc files (like INSTALL) did not properly reflect the changes to the build process and the new doc. Fixed that. - changed syslogd.c so that when compiled without database support, an error message is displayed when a database action is detected in the config file (previously this was used as an user rule ;)) - fixed a bug in the os-specific Makefiles which caused MySQL support to not be compiled, even if selected --------------------------------------------------------------------------- Version 0.9.6 (RGer), 2005-08-09 - greatly enhanced documentation. Now available in html format in the "doc" folder and FreeBSD. Finally includes an install howto. - improved MySQL error messages a little - they now show up as log messages, too (formerly only in debug mode) - added the ability to specify the listen port for udp syslog. WARNING: This introduces an incompatibility. Formerly, udp syslog was enabled by the -r command line option. Now, it is "-r [port]", which is consistent with the tcp listener. However, just -r will now return an error message. - added sample startup scripts for Debian and FreeBSD - added support for easy feature selection in the makefile. Un- fortunately, this also means I needed to spilt the make file for different OS and distros. There are some really bad syntax differences between FreeBSD and Linux make. --------------------------------------------------------------------------- Version 0.9.5 (RGer), 2005-08-01 - the "semicolon bug" was actually not (fully) solved in 0.9.4. One part of the bug was solved, but another still existed. This one is fixed now, too. - the "semicolon bug" actually turned out to be a more generic bug. It appeared whenever an invalid template name was given. With some selector actions, rsyslogd dumped core, with other it "just" had a small ressource leak with others all worked well. These anomalies are now fixed. Note that they only appeared during system initaliziation once the system was running, nothing bad happened. - improved error reporting for template errors on startup. They are now shown on the console and the start-up tty. Formerly, they were only visible in debug mode. - support for multiple instances of rsyslogd on a single machine added - added new option "-o" --> omit local unix domain socket. This option enables rsyslogd NOT to listen to the local socket. This is most helpful when multiple instances of rsyslogd (or rsyslogd and another syslogd) shall run on a single system. - added new option "-i " which allows to specify the pidfile. This is needed when multiple instances of rsyslogd are to be run. - the new project home page is now online at www.rsyslog.com --------------------------------------------------------------------------- Version 0.9.4 (RGer), 2005-07-25 - finally added the TCP sender. It now supports non-blocking mode, no longer disabling message reception during connect. As it is now, it is usable in production. The code could be more sophisticated, but I've kept it short in anticipation of the move to liblogging, which will lead to the removal of the code just written ;) - the "exiting on signal..." message still had the "syslogd" name in it. Changed this to "rsyslogd", as we do not have a large user base yet, this should pose no problem. - fixed "the semiconlon" bug. rsyslogd dumped core if a write-db action was specified but no semicolon was given after the password (an empty template was ok, but the semicolon needed to be present). - changed a default for traditional output format. During testing, it was seen that the timestamp written to file in default format was the time of message reception, not the time specified in the TIMESTAMP field of the message itself. Traditionally, the message TIMESTAMP is used and this has been changed now. --------------------------------------------------------------------------- Version 0.9.3 (RGer), 2005-07-19 - fixed a bug in the message parser. In June, the RFC 3164 timestamp was not correctly parsed (yes, only in June and some other months, see the code comment to learn why...) - added the ability to specify the destination port when forwarding syslog messages (both for TCP and UDP) - added an very experimental TCP sender (activated by @@machine:port in config). This is not yet for production use. If the receiver is not alive, rsyslogd will wait quite some time until the connection request times out, which most probably leads to loss of incoming messages. --------------------------------------------------------------------------- Version 0.9.2 (RGer), around 2005-07-06 - I intended to change the maxsupported message size to 32k to support IHE - but given the memory inefficiency in the usual use cases, I have not done this. I have, however, included very specific instructions on how to do this in the source code. I have also done some testing with 32k messages, so you can change the max size without taking too much risk. - added a syslog/tcp receiver; we now can receive messages via plain tcp, but we can still send only via UDP. The syslog/tcp receiver is the primary enhancement of this release. - slightly changed some error messages that contained a spurios \n at the end of the line (which gives empty lines in your log...) --------------------------------------------------------------------------- Version 0.9.1 (RGer) - fixed code so that it compiles without errors under FreeBSD - removed now unused function "allocate_log()" from syslogd.c - changed the make file so that it contains more defines for different environments (in the long term, we need a better system for disabling/enabling features...) - changed some printf's printing off_t types to %lld and explicit (long long) casts. I tried to figure out the exact type, but did not succeed in this. In the worst case, ultra-large peta- byte files will now display funny informational messages on rollover, something I think we can live with for the neersion 3.11.2 (rgerhards), 2008-02-?? --------------------------------------------------------------------------- Version 3.11.1 (rgerhards), 2008-02-12 - SNMP trap sender added thanks to Andre Lorbach (omsnmp) - added input-plugin interface specification in form of a (copy) template input module - applied documentation fix by Michael Biebl -- many thanks! - bugfix: immark did not have MARK flags set... - added x-info field to rsyslogd startup/shutdown message. Hopefully points users to right location for further info (many don't even know they run rsyslog ;)) - bugfix: trailing ":" of tag was lost while parsing legacy syslog messages without timestamp - thanks to Anders Blomdell for providing a patch! - fixed a bug in stringbuf.c related to STRINGBUF_TRIM_ALLOCSIZE, which wasn't supposed to be used with rsyslog. Put a warning message up that tells this feature is not tested and probably not worth the effort. Thanks to Anders Blomdell fro bringing this to our attention - somewhat improved performance of string buffers - fixed bug that caused invalid treatment of tabs (HT) in rsyslog.conf - bugfix: setting for $EscapeCopntrolCharactersOnReceive was not properly initialized - clarified usage of space-cc property replacer option - improved abort diagnostic handler - some initial effort for malloc/free runtime debugging support - bugfix: using dynafile actions caused rsyslogd abort - fixed minor man errors thanks to Michael Biebl --------------------------------------------------------------------------- Version 3.11.0 (rgerhards), 2008-01-31 - implemented queued actions - implemented simple rate limiting for actions - implemented deliberate discarding of lower priority messages over higher priority ones when a queue runs out of space - implemented disk quotas for disk queues - implemented the $ActionResumeRetryCount config directive - added $ActionQueueFilename config directive - added $ActionQueueSize config directive - added $ActionQueueHighWaterMark config directive - added $ActionQueueLowWaterMark config directive - added $ActionQueueDiscardMark config directive - added $ActionQueueDiscardSeverity config directive - added $ActionQueueCheckpointInterval config directive - added $ActionQueueType config directive - added $ActionQueueWorkerThreads config directive - added $ActionQueueTimeoutshutdown config directive - added $ActionQueueTimeoutActionCompletion config directive - added $ActionQueueTimeoutenQueue config directive - added $ActionQueueTimeoutworkerThreadShutdown config directive - added $ActionQueueWorkerThreadMinimumMessages config directive - added $ActionQueueMaxFileSize config directive - added $ActionQueueSaveonShutdown config directive - addded $ActionQueueDequeueSlowdown config directive - addded $MainMsgQueueDequeueSlowdown config directive - bugfix: added forgotten docs to package - improved debugging support - fixed a bug that caused $MainMsgQueueCheckpointInterval to work incorrectly - when a long-running action needs to be cancelled on shutdown, the message that was processed by it is now preserved. This finishes support for guaranteed delivery of messages (if the output supports it, of course) - fixed bug in output module interface, see http://sourceforge.net/tracker/index.php?func=detail&aid=1881008&group_id=123448&atid=696552 - changed the ommysql output plugin so that the (lengthy) connection initialization now takes place in message processing. This works much better with the new queued action mode (fast startup) - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! - bugfixed stream class offset handling on 32bit platforms --------------------------------------------------------------------------- Version 3.10.3 (rgerhards), 2008-01-28 - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - run-time instrumentation added - implemented disk-assisted queue mode, which enables on-demand disk spooling if the queue's in-memory queue is exhausted - implemented a dynamic worker thread pool for processing incoming messages; workers are started and shut down as need arises - implemented a run-time instrumentation debug package - implemented the $MainMsgQueueSaveOnShutdown config directive - implemented the $MainMsgQueueWorkerThreadMinimumMessages config directive - implemented the $MainMsgQueueTimeoutWorkerThreadShutdown config directive --------------------------------------------------------------------------- Version 3.10.2 (rgerhards), 2008-01-14 - added the ability to keep stop rsyslogd without the need to drain the main message queue. In disk queue mode, rsyslog continues to run from the point where it stopped. In case of a system failure, it continues to process messages from the last checkpoint. - fixed a bug that caused a segfault on startup when no $WorkDir directive was specified in rsyslog.conf - provided more fine-grain control over shutdown timeouts and added a way to specify the enqueue timeout when the main message queue is full - implemented $MainMsgQueueCheckpointInterval config directive - implemented $MainMsgQueueTimeoutActionCompletion config directive - implemented $MainMsgQueueTimeoutEnqueue config directive - implemented $MainMsgQueueTimeoutShutdown config directive --------------------------------------------------------------------------- Version 3.10.1 (rgerhards), 2008-01-10 - implemented the "disk" queue mode. However, it currently is of very limited use, because it does not support persistence over rsyslogd runs. So when rsyslogd is stopped, the queue is drained just as with the in-memory queue modes. Persistent queues will be a feature of the next release. - performance-optimized string class, should bring an overall improvement - fixed a memory leak in imudp -- thanks to varmojfekoj for the patch - fixed a race condition that could lead to a rsyslogd hang when during HUP or termination - done some doc updates - added $WorkDirectory config directive - added $MainMsgQueueFileName config directive - added $MainMsgQueueMaxFileSize config directive --------------------------------------------------------------------------- Version 3.10.0 (rgerhards), 2008-01-07 - implemented input module interface and initial input modules - enhanced threading for input modules (each on its own thread now) - ability to bind UDP listeners to specific local interfaces/ports and ability to run multiple of them concurrently - added ability to specify listen IP address for UDP syslog server - license changed to GPLv3 - mark messages are now provided by loadble module immark - rklogd is no longer provided. Its functionality has now been taken over by imklog, a loadable input module. This offers a much better integration into rsyslogd and makes sure that the kernel logger process is brought up and down at the appropriate times - enhanced $IncludeConfig directive to support wildcard characters (thanks to Michael Biebl) - all inputs are now implemented as loadable plugins - enhanced threading model: each input module now runs on its own thread - enhanced message queue which now supports different queueing methods (among others, this can be used for performance fine-tuning) - added a large number of new configuration directives for the new input modules - enhanced multi-threading utilizing a worker thread pool for the main message queue - compilation without pthreads is no longer supported - much cleaner code due to new objects and removal of single-threading mode --------------------------------------------------------------------------- Version 2.0.1 STABLE (rgerhards), 2008-01-24 - fixed a bug in integer conversion - but this function was never called, so it is not really a useful bug fix ;) - fixed a bug with standard template definitions (not a big deal) - thanks to varmojfekoj for spotting it - fixed a bug that caused a potential hang in file and fwd output module varmojfekoj provided the patch - many thanks! --------------------------------------------------------------------------- Version 2.0.0 STABLE (rgerhards), 2008-01-02 - re-release of 1.21.2 as STABLE with no modifications except some doc updates --------------------------------------------------------------------------- Version 1.21.2 (rgerhards), 2007-12-28 - created a gss-api output module. This keeps GSS-API code and TCP/UDP code separated. It is also important for forward- compatibility with v3. Please note that this change breaks compatibility with config files created for 1.21.0 and 1.21.1 - this was considered acceptable. - fixed an error in forwarding retry code (could lead to message corruption but surfaced very seldom) - increased portability for older platforms (AI_NUMERICSERV moved) - removed socket leak in omfwd.c - cross-platform patch for GSS-API compile problem on some platforms thanks to darix for the patch! --------------------------------------------------------------------------- Version 1.21.1 (rgerhards), 2007-12-23 - small doc fix for $IncludeConfig - fixed a bug in llDestroy() - bugfix: fixing memory leak when message queue is full and during parsing. Thanks to varmojfekoj for the patch. - bugfix: when compiled without network support, unix sockets were not properply closed - bugfix: memory leak in cfsysline.c/doGetWord() fixed --------------------------------------------------------------------------- Version 1.21.0 (rgerhards), 2007-12-19 - GSS-API support for syslog/TCP connections was added. Thanks to varmojfekoj for providing the patch with this functionality - code cleanup - enhanced $IncludeConfig directive to support wildcard filenames - changed some multithreading synchronization --------------------------------------------------------------------------- Version 1.20.1 (rgerhards), 2007-12-12 - corrected a debug setting that survived release. Caused TCP connections to be retried unnecessarily often. - When a hostname ACL was provided and DNS resolution for that name failed, ACL processing was stopped at that point. Thanks to mildew for the patch. Fedora Bugzilla: http://bugzilla.redhat.com/show_bug.cgi?id=395911 - fixed a potential race condition, see link for details: http://rgerhards.blogspot.com/2007/12/rsyslog-race-condition.html Note that the probability of problems from this bug was very remote - fixed a memory leak that happend when PostgreSQL date formats were used --------------------------------------------------------------------------- Version 1.20.0 (rgerhards), 2007-12-07 - an output module for postgres databases has been added. Thanks to sur5r for contributing this code - unloading dynamic modules has been cleaned up, we now have a real implementation and not just a dummy "good enough for the time being". - enhanced platform independence - thanks to Bartosz Kuzma and Michael Biebl for their very useful contributions - some general code cleanup (including warnings on 64 platforms, only) --------------------------------------------------------------------------- Version 1.19.12 (rgerhards), 2007-12-03 - cleaned up the build system (thanks to Michael Biebl for the patch) - fixed a bug where ommysql was still not compiled with -pthread option --------------------------------------------------------------------------- Version 1.19.11 (rgerhards), 2007-11-29 - applied -pthread option to build when building for multi-threading mode hopefully solves an issue with segfaulting --------------------------------------------------------------------------- Version 1.19.10 (rgerhards), 2007-10-19 - introdcued the new ":modulename:" syntax for calling module actions in selector lines; modified ommysql to support it. This is primarily an aid for further modules and a prequisite to actually allow third party modules to be created. - minor fix in slackware startup script, "-r 0" is now "-r0" - updated rsyslogd doc set man page; now in html format - undid creation of a separate thread for the main loop -- this did not turn out to be needed or useful, so reduce complexity once again. - added doc fixes provided by Michael Biebl - thanks --------------------------------------------------------------------------- Version 1.19.9 (rgerhards), 2007-10-12 - now packaging system which again contains all components in a single tarball - modularized main() a bit more, resulting in less complex code - experimentally added an additional thread - will see if that affects the segfault bug we experience on some platforms. Note that this change is scheduled to be removed again later. --------------------------------------------------------------------------- Version 1.19.8 (rgerhards), 2007-09-27 - improved repeated message processing - applied patch provided by varmojfekoj to support building ommysql in its own way (now also resides in a plugin subdirectory); ommysql is now a separate package - fixed a bug in cvthname() that lead to message loss if part of the source hostname would have been dropped - created some support for distributing ommysql together with the main rsyslog package. I need to re-think it in the future, but for the time being the current mode is best. I now simply include one additional tarball for ommysql inside the main distribution. I look forward to user feedback on how this should be done best. In the long term, a separate project should be spawend for ommysql, but I'd like to do that only after the plugin interface is fully stable (what it is not yet). --------------------------------------------------------------------------- Version 1.19.7 (rgerhards), 2007-09-25 - added code to handle situations where senders send us messages ending with a NUL character. It is now simply removed. This also caused trailing LF reduction to fail, when it was followed by such a NUL. This is now also handled. - replaced some non-thread-safe function calls by their thread-safe counterparts - fixed a minor memory leak that occured when the %APPNAME% property was used (I think nobody used that in practice) - fixed a bug that caused signal handlers in cvthname() not to be restored when a malicious pointer record was detected and processing of the message been stopped for that reason (this should be really rare and can not be related to the segfault bug we are hunting). - fixed a bug in cvthname that lead to passing a wrong parameter - in practice, this had no impact. - general code cleanup (e.g. compiler warnings, comments) --------------------------------------------------------------------------- Version 1.19.6 (rgerhards), 2007-09-11 - applied patch by varmojfekoj to change signal handling to the new sigaction API set (replacing the depreciated signal() calls and its friends. - fixed a bug that in --enable-debug mode caused an assertion when the discard action was used - cleaned up compiler warnings - applied patch by varmojfekoj to FIX a bug that could cause segfaults if empty properties were processed using modifying options (e.g. space-cc, drop-cc) - fixed man bug: rsyslogd supports -l option --------------------------------------------------------------------------- Version 1.19.5 (rgerhards), 2007-09-07 - changed part of the CStr interface so that better error tracking is provided and the calling sequence is more intuitive (there were invalid calls based on a too-weired interface) - (hopefully) fixed some remaining bugs rooted in wrong use of the CStr class. These could lead to program abort. - applied patch by varmojfekoj two fix two potential segfault situations - added $ModDir config directive - modified $ModLoad so that an absolute path may be specified as module name (e.g. /rsyslog/ommysql.so) --------------------------------------------------------------------------- Version 1.19.4 (rgerhards/varmojfekoj), 2007-09-04 - fixed a number of small memory leaks - thanks varmojfekoj for patching - fixed an issue with CString class that could lead to rsyslog abort in tplToString() - thanks varmojfekoj for patching - added a man-version of the config file documenation - thanks to Michel Samia for providing the man file - fixed bug: a template like this causes an infinite loop: $template opts,"%programname:::a,b%" thanks varmojfekoj for the patch - fixed bug: case changing options crash freeing the string pointer because they modify it: $template opts2,"%programname::1:lowercase%" thanks varmojfekoj for the patch --------------------------------------------------------------------------- Version 1.19.3 (mmeckelein/varmojfekoj), 2007-08-31 - small mem leak fixed (after calling parseSelectorAct) - Thx varmojkekoj - documentation section "Regular File" und "Blocks" updated - solved an issue with dynamic file generation - Once again many thanks to varmojfekoj - the negative selector for program name filter (Blocks) does not work as expected - Thanks varmojfekoj for patching - added forwarding information to sysklogd (requires special template) to config doc --------------------------------------------------------------------------- Version 1.19.2 (mmeckelein/varmojfekoj), 2007-08-28 - a specifically formed message caused a segfault - Many thanks varmojfekoj for providing a patch - a typo and a weird condition are fixed in msg.c - Thanks again varmojfekoj - on file creation the file was always owned by root:root. This is fixed now - Thanks ypsa for solving this issue --------------------------------------------------------------------------- Version 1.19.1 (mmeckelein), 2007-08-22 - a bug that caused a high load when a TCP/UDP connection was closed is fixed now - Thanks mildew for solving this issue - fixed a bug which caused a segfault on reinit - Thx varmojfekoj for the patch - changed the hardcoded module path "/lib/rsyslog" to $(pkglibdir) in order to avoid trouble e.g. on 64 bit platforms (/lib64) - many thanks Peter Vrabec and darix, both provided a patch for solving this issue - enhanced the unloading of modules - thanks again varmojfekoj - applied a patch from varmojfekoj which fixes various little things in MySQL output module --------------------------------------------------------------------------- Version 1.19.0 (varmojfekoj/rgerhards), 2007-08-16 - integrated patch from varmojfekoj to make the mysql module a loadable one many thanks for the patch, MUCH appreciated --------------------------------------------------------------------------- Version 1.18.2 (rgerhards), 2007-08-13 - fixed a bug in outchannel code that caused templates to be incorrectly parsed - fixed a bug in ommysql that caused a wrong ";template" missing message - added some code for unloading modules; not yet fully complete (and we do not yet have loadable modules, so this is no problem) - removed debian subdirectory by request of a debian packager (this is a special subdir for debian and there is also no point in maintaining it when there is a debian package available - so I gladly did this) in some cases - improved overall doc quality (some pages were quite old) and linked to more of the online resources. - improved /contrib/delete_mysql script by adding a host option and some other minor modifications --------------------------------------------------------------------------- Version 1.18.1 (rgerhards), 2007-08-08 - applied a patch from varmojfekoj which solved a potential segfault of rsyslogd on HUP - applied patch from Michel Samia to fix compilation when the pthreads feature is disabled - some code cleanup (moved action object to its own file set) - add config directive $MainMsgQueueSize, which now allows to configure the queue size dynamically - all compile-time settings are now shown in rsyslogd -v, not just the active ones - enhanced performance a little bit more - added config file directive $ActionResumeInterval - fixed a bug that prevented compilation under debian sid - added a contrib directory for user-contributed useful things --------------------------------------------------------------------------- Version 1.18.0 (rgerhards), 2007-08-03 - rsyslog now supports fallback actions when an action did not work. This is a great feature e.g. for backup database servers or backup syslog servers - modified rklogd to only change the console log level if -c is specified - added feature to use multiple actions inside a single selector - implemented $ActionExecOnlyWhenPreviousIsSuspended config directive - error messages during startup are now spit out to the configured log destinations --------------------------------------------------------------------------- Version 1.17.6 (rgerhards), 2007-08-01 - continued to work on output module modularization - basic stage of this work is now FINISHED - fixed bug in OMSRcreate() - always returned SR_RET_OK - fixed a bug that caused ommysql to always complain about missing templates - fixed a mem leak in OMSRdestruct - freeing the object itself was forgotten - thanks to varmojfekoj for the patch - fixed a memory leak in syslogd/init() that happend when the config file could not be read - thanks to varmojfekoj for the patch - fixed insufficient memory allocation in addAction() and its helpers. The initial fix and idea was developed by mildew, I fine-tuned it a bit. Thanks a lot for the fix, I'd probably had pulled out my hair to find the bug... - added output of config file line number when a parsing error occured - fixed bug in objomsr.c that caused program to abort in debug mode with an invalid assertion (in some cases) - fixed a typo that caused the default template for MySQL to be wrong. thanks to mildew for catching this. - added configuration file command $DebugPrintModuleList and $DebugPrintCfSysLineHandlerList - fixed an invalid value for the MARK timer - unfortunately, there was a testing aid left in place. This resulted in quite frequent MARK messages - added $IncludeConfig config directive - applied a patch from mildew to prevent rsyslogd from freezing under heavy load. This could happen when the queue was full. Now, we drop messages but rsyslogd remains active. --------------------------------------------------------------------------- Version 1.17.5 (rgerhards), 2007-07-30 - continued to work on output module modularization - fixed a missing file bug - thanks to Andrea Montanari for reporting this problem - fixed a problem with shutting down the worker thread and freeing the selector_t list - this caused messages to be lost, because the message queue was not properly drained before the selectors got destroyed. --------------------------------------------------------------------------- Version 1.17.4 (rgerhards), 2007-07-27 - continued to work on output module modularization - fixed a situation where rsyslogd could create zombie processes thanks to mildew for the patch - applied patch from Michel Samia to fix compilation when NOT compiled for pthreads --------------------------------------------------------------------------- Version 1.17.3 (rgerhards), 2007-07-25 - continued working on output module modularization - fixed a bug that caused rsyslogd to segfault on exit (and probably also on HUP), when there was an unsent message in a selector that required forwarding and the dns lookup failed for that selector (yes, it was pretty unlikely to happen;)) thanks to varmojfekoj for the patch - fixed a memory leak in config file parsing and die() thanks to varmojfekoj for the patch - rsyslogd now checks on startup if it is capable to performa any work at all. If it cant, it complains and terminates thanks to Michel Samia for providing the patch! - fixed a small memory leak when HUPing syslogd. The allowed sender list now gets freed. thanks to mildew for the patch. - changed the way error messages in early startup are logged. They now do no longer use the syslogd code directly but are rather send to stderr. --------------------------------------------------------------------------- Version 1.17.2 (rgerhards), 2007-07-23 - made the port part of the -r option optional. Needed for backward compatibility with sysklogd - replaced system() calls with something more reasonable. Please note that this might break compatibility with some existing configuration files. We accept this in favour of the gained security. - removed a memory leak that could occur if timegenerated was used in RFC 3164 format in templates - did some preparation in msg.c for advanced multithreading - placed the hooks, but not yet any active code - worked further on modularization - added $ModLoad MySQL (dummy) config directive - added DropTrailingLFOnReception config directive --------------------------------------------------------------------------- Version 1.17.1 (rgerhards), 2007-07-20 - fixed a bug that caused make install to install rsyslogd and rklogd under the wrong names - fixed bug that caused $AllowedSenders to handle IPv6 scopes incorrectly; also fixed but that could grabble $AllowedSender wildcards. Thanks to mildew@gmail.com for the patch - minor code cleanup - thanks to Peter Vrabec for the patch - fixed minimal memory leak on HUP (caused by templates) thanks to varmojfekoj for the patch - fixed another memory leak on HUPing and on exiting rsyslogd again thanks to varmojfekoj for the patch - code cleanup (removed compiler warnings) - fixed portability bug in configure.ac - thanks to Bartosz Kuźma for patch - moved msg object into its own file set - added the capability to continue trying to write log files when the file system is full. Functionality based on patch by Martin Schulze to sysklogd package. --------------------------------------------------------------------------- Version 1.17.0 (RGer), 2007-07-17 - added $RepeatedLineReduction config parameter - added $EscapeControlCharactersOnReceive config parameter - added $ControlCharacterEscapePrefix config parameter - added $DirCreateMode config parameter - added $CreateDirs config parameter - added $DebugPrintTemplateList config parameter - added $ResetConfigVariables config parameter - added $FileOwner config parameter - added $FileGroup config parameter - added $DirOwner config parameter - added $DirGroup config parameter - added $FailOnChownFailure config parameter - added regular expression support to the filter engine thanks to Michel Samia for providing the patch! - enhanced $AllowedSender functionality. Credits to mildew@gmail.com for the patch doing that - added IPv6 support - allowed DNS hostnames - allowed DNS wildcard names - added new option $DropMsgsWithMaliciousDnsPTRRecords - added autoconf so that rfc3195d, rsyslogd and klogd are stored to /sbin - added capability to auto-create directories with dynaFiles --------------------------------------------------------------------------- Version 1.16.0 (RGer/Peter Vrabec), 2007-07-13 - The Friday, 13th Release ;) - build system switched to autotools - removed SYSV preprocessor macro use, replaced with autotools equivalents - fixed a bug that caused rsyslogd to segfault when TCP listening was disabled and it terminated - added new properties "syslogfacility-text" and "syslogseverity-text" thanks to varmojfekoj for the patch - added the -x option to disable hostname dns reslution thanks to varmojfekoj for the patch - begun to better modularize syslogd.c - this is an ongoing project; moved type definitions to a separate file - removed some now-unused fields from struct filed - move file size limit fields in struct field to the "right spot" (the file writing part of the union - f_un.f_file) - subdirectories linux and solaris are no longer part of the distribution package. This is not because we cease support for them, but there are no longer any files in them after the move to autotools --------------------------------------------------------------------------- Version 1.15.1 (RGer), 2007-07-10 - fixed a bug that caused a dynaFile selector to stall when there was an open error with one file - improved template processing for dynaFiles; templates are now only looked up during initialization - speeds up processing - optimized memory layout in struct filed when compiled with MySQL support - fixed a bug that caused compilation without SYSLOG_INET to fail - re-enabled the "last message repeated n times" feature. This feature was not taken care of while rsyslogd evolved from sysklogd and it was more or less defunct. Now it is fully functional again. - added system properties: $NOW, $YEAR, $MONTH, $DAY, $HOUR, $MINUTE - fixed a bug in iovAsString() that caused a memory leak under stress conditions (most probably memory shortage). This was unlikely to ever happen, but it doesn't hurt doing it right - cosmetic: defined type "uchar", change all unsigned chars to uchar --------------------------------------------------------------------------- Version 1.15.0 (RGer), 2007-07-05 - added ability to dynamically generate file names based on templates and thus properties. This was a much-requested feature. It makes life easy when it e.g. comes to splitting files based on the sender address. - added $umask and $FileCreateMode config file directives - applied a patch from Bartosz Kuzma to compile cleanly under NetBSD - checks for extra (unexpected) characters in system config file lines have been added - added IPv6 documentation - was accidently missing from CVS - begun to change char to unsigned char --------------------------------------------------------------------------- Version 1.14.2 (RGer), 2007-07-03 ** this release fixes all known nits with IPv6 ** - restored capability to do /etc/service lookup for "syslog" service when -r 0 was given - documented IPv6 handling of syslog messages - integrate patch from Bartosz Kuźma to make rsyslog compile under Solaris again (the patch replaced a strndup() call, which is not available under Solaris - improved debug logging when waiting on select - updated rsyslogd man page with new options (-46A) --------------------------------------------------------------------------- Version 1.14.1 (RGer/Peter Vrabec), 2007-06-29 - added Peter Vrabec's patch for IPv6 TCP - prefixed all messages send to stderr in rsyslogd with "rsyslogd: " --------------------------------------------------------------------------- Version 1.14.0 (RGer/Peter Vrabec), 2007-06-28 - Peter Vrabec provided IPv6 for rsyslog, so we are now IPv6 enabled IPv6 Support is currently for UDP only, TCP is to come soon. AllowedSender configuration does not yet work for IPv6. - fixed code in iovCreate() that broke C's strict aliasing rules - fixed some char/unsigned char differences that forced the compiler to spit out warning messages - updated the Red Hat init script to fix a known issue (thanks to Peter Vrabec) --------------------------------------------------------------------------- Version 1.13.5 (RGer), 2007-06-22 - made the TCP session limit configurable via command line switch now -t , - added man page for rklogd(8) (basically a copy from klogd, but now there is one...) - fixed a bug that caused internal messages (e.g. rsyslogd startup) to appear without a tag. - removed a minor memory leak that occurred when TAG processing requalified a HOSTNAME to be a TAG (and a TAG already was set). - removed potential small memory leaks in MsgSet***() functions. There would be a leak if a property was re-set, something that happened extremely seldom. --------------------------------------------------------------------------- Version 1.13.4 (RGer), 2007-06-18 - added a new property "PRI-text", which holds the PRI field in textual form (e.g. "syslog.info") - added alias "syslogseverity" for "syslogpriority", which is a misleading property name that needs to stay for historical reasons (and backward-compatility) - added doc on how to record PRI value in log file - enhanced signal handling in klogd, including removal of an unsafe call to the logging system during signal handling --------------------------------------------------------------------------- Version 1.13.3 (RGer), 2007-06-15 - create a version of syslog.c from scratch. This is now - highly optimized for rsyslog - removes an incompatible license problem as the original version had a BSD license with advertising clause - fixed in the regard that rklogd will continue to work when rsysogd has been restarted (the original version, as well as sysklogd, will remain silent then) - solved an issue with an extra NUL char at message end that the original version had - applied some changes to klogd to care for the new interface - fixed a bug in syslogd.c which prevented compiling under debian --------------------------------------------------------------------------- Version 1.13.2 (RGer), 2007-06-13 - lib order in makefile patched to facilitate static linking - thanks to Bennett Todd for providing the patch - Integrated a patch from Peter Vrabec (pvrabec@redheat.com): - added klogd under the name of rklogd (remove dependency on original sysklogd package - createDB.sql now in UTF - added additional config files for use on Red Hat --------------------------------------------------------------------------- Version 1.13.1 (RGer), 2007-02-05 - changed the listen backlog limit to a more reasonable value based on the maximum number of TCP connections configurd (10% + 5) - thanks to Guy Standen for the hint (actually, the limit was 5 and that was a left-over from early testing). - fixed a bug in makefile which caused DB-support to be disabled when NETZIP support was enabled - added the -e option to allow transmission of every message to remote hosts (effectively turns off duplicate message suppression) - (somewhat) improved memory consumption when compiled with MySQL support - looks like we fixed an incompatibility with MySQL 5.x and above software At least in one case, the remote server name was destroyed, leading to a connection failure. The new, improved code does not have this issue and so we see this as solved (the new code is generally somewhat better, so there is a good chance we fixed this incompatibility). --------------------------------------------------------------------------- Version 1.13.0 (RGer), 2006-12-19 - added '$' as ToPos proptery replacer specifier - means "up to the end of the string" - property replacer option "escape-cc", "drop-cc" and "space-cc" added - changed the handling of \0 characters inside syslog messages. We now consistently escape them to "#000". This is somewhat recommended in the draft-ietf-syslog-protocol-19 draft. While the real recomendation is to not escape any characters at all, we can not do this without considerable modification of the code. So we escape it to "#000", which is consistent with a sample found in the Internet-draft. - removed message glue logic (see printchopped() comment for details) Also caused removal of parts table and thus some improvements in memory usage. - changed the default MAXLINE to 2048 to take care of recent syslog standardization efforts (can easily be changed in syslogd.c) - added support for byte-counted TCP syslog messages (much like syslog-transport-tls-05 Internet Draft). This was necessary to support compression over TCP. - added support for receiving compressed syslog messages - added support for sending compressed syslog messages - fixed a bug where the last message in a syslog/tcp stream was lost if it was not properly terminated by a LF character --------------------------------------------------------------------------- Version 1.12.3 (RGer), 2006-10-04 - implemented some changes to support Solaris (but support is not yet complete) - commented out (via #if 0) some methods that are currently not being use but should be kept for further us - added (interim) -u 1 option to turn off hostname and tag parsing - done some modifications to better support Fedora - made the field delimiter inside property replace configurable via template - fixed a bug in property replacer: if fields were used, the delimitor became part of the field. Up until now, this was barely noticable as the delimiter as TAB only and thus invisible to a human. With other delimiters available now, it quickly showed up. This bug fix might cause some grief to existing installations if they used the extra TAB for whatever reasons - sorry folks... Anyhow, a solution is easy: just add a TAB character contstant into your template. Thus, there has no attempt been made to do this in a backwards-compatible way. --------------------------------------------------------------------------- Version 1.12.2 (RGer), 2006-02-15 - fixed a bug in the RFC 3339 date formatter. An extra space was added after the actual timestamp - added support for providing high-precision RFC3339 timestamps for (rsyslogd-)internally-generated messages - very (!) experimental support for syslog-protocol internet draft added (the draft is experimental, the code is solid ;)) - added support for field-extracting in the property replacer - enhanced the legacy-syslog parser so that it can interpret messages that do not contain a TIMESTAMP - fixed a bug that caused the default socket (usually /dev/log) to be opened even when -o command line option was given - fixed a bug in the Debian sample startup script - it caused rsyslogd to listen to remote requests, which it shouldn't by default --------------------------------------------------------------------------- Version 1.12.1 (RGer), 2005-11-23 - made multithreading work with BSD. Some signal-handling needed to be restructured. Also, there might be a slight delay of up to 10 seconds when huping and terminating rsyslogd under BSD - fixed a bug where a NULL-pointer was passed to printf() in logmsg(). - fixed a bug during "make install" where rc3195d was not installed Thanks to Bennett Todd for spotting this. - fixed a bug where rsyslogd dumped core when no TAG was found in the received message - enhanced message parser so that it can deal with missing hostnames in many cases (may not be totally fail-safe) - fixed a bug where internally-generated messages did not have the correct TAG --------------------------------------------------------------------------- Version 1.12.0 (RGer), 2005-10-26 - moved to a multi-threaded design. single-threading is still optionally available. Multi-threading is experimental! - fixed a potential race condition. In the original code, marking was done by an alarm handler, which could lead to all sorts of bad things. This has been changed now. See comments in syslogd.c/domark() for details. - improved debug output for property-based filters - not a code change, but: I have checked all exit()s to make sure that none occurs once rsyslogd has started up. Even in unusual conditions (like low-memory conditions) rsyslogd somehow remains active. Of course, it might loose a message or two, but at least it does not abort and it can also recover when the condition no longer persists. - fixed a bug that could cause loss of the last message received immediately before rsyslogd was terminated. - added comments on thread-safety of global variables in syslogd.c - fixed a small bug: spurios printf() when TCP syslog was used - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug with regular expression support (thanks to Andres Riancho) - a little bit of code restructuring (especially main(), which was horribly large) --------------------------------------------------------------------------- Version 1.11.1 (RGer), 2005-10-19 - support for BSD-style program name and host blocks - added a new property "programname" that can be used in templates - added ability to specify listen port for rfc3195d - fixed a bug that rendered the "startswith" comparison operation unusable. - changed more functions to "static" storage class to help compiler optimize (should have been static in the first place...) - fixed a potential memory leak in the string buffer class destructor. As the destructur was previously never called, the leak did not actually appear. - some internal restructuring in anticipation/preparation of minimal multi-threading support - rsyslogd still shares some code with the sysklogd project. Some patches for this shared code have been brought over from the sysklogd CVS. --------------------------------------------------------------------------- Version 1.11.0 (RGer), 2005-10-12 - support for receiving messages via RFC 3195; added rfc3195d for that purpose - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases --------------------------------------------------------------------------- Version 1.10.2 (RGer), 2005-09-27 - added comparison operations in property-based filters: * isequal * startswith - added ability to negate all property-based filter comparison operations by adding a !-sign right in front of the operation name - added the ability to specify remote senders for UDP and TCP received messages. Allows to block all but well-known hosts - changed the $-config line directives to be case-INsensitive - new command line option -w added: "do not display warnings if messages from disallowed senders are received" - fixed a bug that caused rsyslogd to dump core when the compare value was not quoted in property-based filters - fixed a bug in the new CStr compare function which lead to invalid results (fortunately, this function was not yet used widely) - added better support for "debugging" rsyslog.conf property filters (only if -d switch is given) - changed some function definitions to static, which eventually enables some compiler optimizations - fixed a bug in MySQL code; when a SQL error occured, rsyslogd could run in a tight loop. This was due to invalid sequence of error reporting and is now fixed. --------------------------------------------------------------------------- Version 1.10.1 (RGer), 2005-09-23 - added the ability to execute a shell script as an action. Thanks to Bjoern Kalkbrenner for providing the code! - fixed a bug in the MySQL code; due to the bug the automatic one-time retry after an error did not happen - this lead to error message in cases where none should be seen (e.g. after a MySQL restart) - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.10.0 (RGer), 2005-09-20 REMINDER: 1.10 is the first unstable version if the 1.x series! - added the capability to filter on any property in selector lines (not just facility and priority) - changed stringbuf into a new counted string class - added support for a "discard" action. If a selector line with discard (~ character) is found, no selector lines *after* that line will be processed. - thanks to Andres Riancho, regular expression support has been added to the template engine - added the FROMHOST property in the template processor, which could previously not be obtained. Thanks to Cristian Testa for pointing this out and even providing a fix. - added display of compile-time options to -v output - performance improvement for production build - made some checks to happen only during debug mode - fixed a problem with compiling on SUSE and - while doing so - removed the socket call to set SO_BSDCOMPAT in cases where it is obsolete. --------------------------------------------------------------------------- Version 1.0.4 (RGer), 2006-02-01 - a small but important fix: the tcp receiver had two forgotten printf's in it that caused a lot of unnecessary output to stdout. This was important enough to justify a new release --------------------------------------------------------------------------- Version 1.0.3 (RGer), 2005-11-14 - added an additional guard to prevent rsyslogd from aborting when the 2gb file size limit is hit. While a user can configure rsyslogd to handle such situations, it would abort if that was not done AND large file support was not enabled (ok, this is hopefully an unlikely scenario) - fixed a bug that caused additional Unix domain sockets to be incorrectly processed - could lead to message loss in extreme cases - applied some patches available from the sysklogd project to code shared from there - fixed a bug that causes rsyslogd to dump core on termination when one of the selector lines did not receive a message during the run (very unlikely) - fixed an one-too-low memory allocation in the TCP sender. Could result in rsyslogd dumping core. - fixed a bug in the TCP sender that caused the retry logic to fail after an error or receiver overrun - fixed a bug in init() that could lead to dumping core - fixed a bug that could lead to dumping core when no HOSTNAME or no TAG was present in the syslog message --------------------------------------------------------------------------- Version 1.0.2 (RGer), 2005-10-05 - fixed an issue with MySQL error reporting. When an error occured, the MySQL driver went into an endless loop (at least in most cases). --------------------------------------------------------------------------- Version 1.0.1 (RGer), 2005-09-23 - fixed a security issue with SQL-escaping in conjunction with non-(SQL-)standard MySQL features. --------------------------------------------------------------------------- Version 1.0.0 (RGer), 2005-09-12 - changed install doc to cover daily cron scripts - a trouble source - added rc script for slackware (provided by Chris Elvidge - thanks!) - fixed a really minor bug in usage() - the -r option was still reported as without the port parameter --------------------------------------------------------------------------- Version 0.9.8 (RGer), 2005-09-05 - made startup and shutdown message more consistent and included the pid, so that they can be easier correlated. Used syslog-protocol structured data format for this purpose. - improved config info in startup message, now tells not only if it is listening remote on udp, but also for tcp. Also includes the port numbers. The previous startup message was misleading, because it did not say "remote reception" if rsyslogd was only listening via tcp (but not via udp). - added a "how can you help" document to the doc set --------------------------------------------------------------------------- Version 0.9.7 (RGer), 2005-08-15 - some of the previous doc files (like INSTALL) did not properly reflect the changes to the build process and the new doc. Fixed that. - changed syslogd.c so that when compiled without database support, an error message is displayed when a database action is detected in the config file (previously this was used as an user rule ;)) - fixed a bug in the os-specific Makefiles which caused MySQL support to not be compiled, even if selected --------------------------------------------------------------------------- Version 0.9.6 (RGer), 2005-08-09 - greatly enhanced documentation. Now available in html format in the "doc" folder and FreeBSD. Finally includes an install howto. - improved MySQL error messages a little - they now show up as log messages, too (formerly only in debug mode) - added the ability to specify the listen port for udp syslog. WARNING: This introduces an incompatibility. Formerly, udp syslog was enabled by the -r command line option. Now, it is "-r [port]", which is consistent with the tcp listener. However, just -r will now return an error message. - added sample startup scripts for Debian and FreeBSD - added support for easy feature selection in the makefile. Un- fortunately, this also means I needed to spilt the make file for different OS and distros. There are some really bad syntax differences between FreeBSD and Linux make. --------------------------------------------------------------------------- Version 0.9.5 (RGer), 2005-08-01 - the "semicolon bug" was actually not (fully) solved in 0.9.4. One part of the bug was solved, but another still existed. This one is fixed now, too. - the "semicolon bug" actually turned out to be a more generic bug. It appeared whenever an invalid template name was given. With some selector actions, rsyslogd dumped core, with other it "just" had a small ressource leak with others all worked well. These anomalies are now fixed. Note that they only appeared during system initaliziation once the system was running, nothing bad happened. - improved error reporting for template errors on startup. They are now shown on the console and the start-up tty. Formerly, they were only visible in debug mode. - support for multiple instances of rsyslogd on a single machine added - added new option "-o" --> omit local unix domain socket. This option enables rsyslogd NOT to listen to the local socket. This is most helpful when multiple instances of rsyslogd (or rsyslogd and another syslogd) shall run on a single system. - added new option "-i " which allows to specify the pidfile. This is needed when multiple instances of rsyslogd are to be run. - the new project home page is now online at www.rsyslog.com --------------------------------------------------------------------------- Version 0.9.4 (RGer), 2005-07-25 - finally added the TCP sender. It now supports non-blocking mode, no longer disabling message reception during connect. As it is now, it is usable in production. The code could be more sophisticated, but I've kept it short in anticipation of the move to liblogging, which will lead to the removal of the code just written ;) - the "exiting on signal..." message still had the "syslogd" name in it. Changed this to "rsyslogd", as we do not have a large user base yet, this should pose no problem. - fixed "the semiconlon" bug. rsyslogd dumped core if a write-db action was specified but no semicolon was given after the password (an empty template was ok, but the semicolon needed to be present). - changed a default for traditional output format. During testing, it was seen that the timestamp written to file in default format was the time of message reception, not the time specified in the TIMESTAMP field of the message itself. Traditionally, the message TIMESTAMP is used and this has been changed now. --------------------------------------------------------------------------- Version 0.9.3 (RGer), 2005-07-19 - fixed a bug in the message parser. In June, the RFC 3164 timestamp was not correctly parsed (yes, only in June and some other months, see the code comment to learn why...) - added the ability to specify the destination port when forwarding syslog messages (both for TCP and UDP) - added an very experimental TCP sender (activated by @@machine:port in config). This is not yet for production use. If the receiver is not alive, rsyslogd will wait quite some time until the connection request times out, which most probably leads to loss of incoming messages. --------------------------------------------------------------------------- Version 0.9.2 (RGer), around 2005-07-06 - I intended to change the maxsupported message size to 32k to support IHE - but given the memory inefficiency in the usual use cases, I have not done this. I have, however, included very specific instructions on how to do this in the source code. I have also done some testing with 32k messages, so you can change the max size without taking too much risk. - added a syslog/tcp receiver; we now can receive messages via plain tcp, but we can still send only via UDP. The syslog/tcp receiver is the primary enhancement of this release. - slightly changed some error messages that contained a spurios \n at the end of the line (which gives empty lines in your log...) --------------------------------------------------------------------------- Version 0.9.1 (RGer) - fixed code so that it compiles without errors under FreeBSD - removed now unused function "allocate_log()" from syslogd.c - changed the make file so that it contains more defines for different environments (in the long term, we need a better system for disabling/enabling features...) - changed some printf's printing off_t types to %lld and explicit (long long) casts. I tried to figure out the exact type, but did not succeed in this. In the worst case, ultra-large peta- byte files will now display funny informational messages on rollover, something I think we can live with for the next 10 years or so... --------------------------------------------------------------------------- Version 0.9.0 (RGer) - changed the filed structure to be a linked list. Previously, it was a table - well, for non-SYSV it was defined as linked list, but from what I see that code did no longer work after my modifications. I am now using a linked list in general because that is needed for other upcoming modifications. - fixed a bug that caused rsyslogd not to listen to anything if the configuration file could not be read - pervious versions disabled network logging (send/receive) if syslog/udp port was not in /etc/services. Now defaulting to port 514 in this case. - internal error messages are now supported up to 256 bytes - error message seen during config file read are now also displayed to the attached tty and not only the console - changed some error messages during init to be sent to the console and/or emergency log. Previously, they were only seen if the -d (debug) option was present on the command line. - fixed the "2gb file issue on 32bit systems". If a file grew to more than 2gb, the syslogd was aborted with "file size exceeded". Now, defines have been added according to http://www.daimi.au.dk/~kasperd/comp.os.linux.development.faq.html#LARGEFILE Testing revealed that they work ;) HOWEVER, if your file system, glibc, kernel, whatever does not support files larger 2gb, you need to set a file size limit with the new output channel mechanism. - updated man pages to reflect the changes --------------------------------------------------------------------------- Version 0.8.4 - improved -d debug output (removed developer-only content) - now compiles under FreeBSD and NetBSD (only quick testing done on NetBSD) --------------------------------------------------------------------------- Version 0.8.3 - security model in "make install" changed - minor doc updates --------------------------------------------------------------------------- Version 0.8.2 - added man page for rsyslog.conf and rsyslogd - gave up on the concept of rsyslog being a "drop in" replacement for syslogd. Now, the user installs rsyslogd and also needs to adjust his system settings to this specifically. This also lead to these changes: * changed Makefile so that install now installs rsyslogd instead of dealing with syslogd * changed the default config file name to rsyslog.conf --------------------------------------------------------------------------- Version 0.8.1 - fixed a nasty memory leak (probably not the last one with this release) - some enhancements to Makefile as suggested by Bennett Todd - syslogd-internal messages (like restart) were missing the hostname this has been corrected --------------------------------------------------------------------------- Version 0.8.0 Initial testing release. Based on the sysklogd package. Thanks to the sysklogd maintainers for all their good work! --------------------------------------------------------------------------- ---------------------------------------------------------------------- The following comments were left in the syslogd source. While they provide not too much detail, the help to date when Rainer started work on the project (which was 2003, now even surprising for Rainer himself ;)). * \author Rainer Gerhards * \date 2003-10-17 * Some initial modifications on the sysklogd package to support * liblogging. These have actually not yet been merged to the * source you see currently (but they hopefully will) * * \date 2004-10-28 * Restarted the modifications of sysklogd. This time, we * focus on a simpler approach first. The initial goal is to * provide MySQL database support (so that syslogd can log * to the database). ---------------------------------------------------------------------- The following comments are from the stock syslogd.c source. They provide some insight into what happened to the source before we forked rsyslogd. However, much of the code already has been replaced and more is to be replaced. So over time, these comments become less valuable. I have moved them out of the syslogd.c file to shrink it, especially as a lot of them do no longer apply. For historical reasons and understanding of how the daemon evolved, they are probably still helpful. * Author: Eric Allman * extensive changes by Ralph Campbell * more extensive changes by Eric Allman (again) * * Steve Lord: Fix UNIX domain socket code, added linux kernel logging * change defines to * SYSLOG_INET - listen on a UDP socket * SYSLOG_UNIXAF - listen on unix domain socket * SYSLOG_KERNEL - listen to linux kernel * * Mon Feb 22 09:55:42 CST 1993: Dr. Wettstein * Additional modifications to the source. Changed priority scheme * to increase the level of configurability. In its stock configuration * syslogd no longer logs all messages of a certain priority and above * to a log file. The * wildcard is supported to specify all priorities. * Note that this is a departure from the BSD standard. * * Syslogd will now listen to both the inetd and the unixd socket. The * strategy is to allow all local programs to direct their output to * syslogd through the unixd socket while the program listens to the * inetd socket to get messages forwarded from other hosts. * * Fri Mar 12 16:55:33 CST 1993: Dr. Wettstein * Thanks to Stephen Tweedie (dcs.ed.ac.uk!sct) for helpful bug-fixes * and an enlightened commentary on the prioritization problem. * * Changed the priority scheme so that the default behavior mimics the * standard BSD. In this scenario all messages of a specified priority * and above are logged. * * Add the ability to specify a wildcard (=) as the first character * of the priority name. Doing this specifies that ONLY messages with * this level of priority are to be logged. For example: * * *.=debug /usr/adm/debug * * Would log only messages with a priority of debug to the /usr/adm/debug * file. * * Providing an * as the priority specifies that all messages are to be * logged. Note that this case is degenerate with specifying a priority * level of debug. The wildcard * was retained because I believe that * this is more intuitive. * * Thu Jun 24 11:34:13 CDT 1993: Dr. Wettstein * Modified sources to incorporate changes in libc4.4. Messages from * syslog are now null-terminated, syslogd code now parses messages * based on this termination scheme. Linux as of libc4.4 supports the * fsync system call. Modified code to fsync after all writes to * log files. * * Sat Dec 11 11:59:43 CST 1993: Dr. Wettstein * Extensive changes to the source code to allow compilation with no * complaints with -Wall. * * Reorganized the facility and priority name arrays so that they * compatible with the syslog.h source found in /usr/include/syslog.h. * NOTE that this should really be changed. The reason I do not * allow the use of the values defined in syslog.h is on account of * the extensions made to allow the wildcard character in the * priority field. To fix this properly one should malloc an array, * copy the contents of the array defined by syslog.h and then * make whatever modifications that are desired. Next round. * * Thu Jan 6 12:07:36 CST 1994: Dr. Wettstein * Added support for proper decomposition and re-assembly of * fragment messages on UNIX domain sockets. Lack of this capability * was causing 'partial' messages to be output. Since facility and * priority information is encoded as a leader on the messages this * was causing lines to be placed in erroneous files. * * Also added a patch from Shane Alderton (shane@ion.apana.org.au) to * correct a problem with syslogd dumping core when an attempt was made * to write log messages to a logged-on user. Thank you. * * Many thanks to Juha Virtanen (jiivee@hut.fi) for a series of * interchanges which lead to the fixing of problems with messages set * to priorities of none and emerg. Also thanks to Juha for a patch * to exclude users with a class of LOGIN from receiving messages. * * Shane Alderton provided an additional patch to fix zombies which * were conceived when messages were written to multiple users. * * Mon Feb 6 09:57:10 CST 1995: Dr. Wettstein * Patch to properly reset the single priority message flag. Thanks * to Christopher Gori for spotting this bug and forwarding a patch. * * Wed Feb 22 15:38:31 CST 1995: Dr. Wettstein * Added version information to startup messages. * * Added defines so that paths to important files are taken from * the definitions in paths.h. Hopefully this will insure that * everything follows the FSSTND standards. Thanks to Chris Metcalf * for a set of patches to provide this functionality. Also thanks * Elias Levy for prompting me to get these into the sources. * * Wed Jul 26 18:57:23 MET DST 1995: Martin Schulze * Linux' gethostname only returns the hostname and not the fqdn as * expected in the code. But if you call hostname with an fqdn then * gethostname will return an fqdn, so we have to mention that. This * has been changed. * * The 'LocalDomain' and the hostname of a remote machine is * converted to lower case, because the original caused some * inconsistency, because the (at least my) nameserver did respond an * fqdn containing of upper- _and_ lowercase letters while * 'LocalDomain' consisted only of lowercase letters and that didn't * match. * * Sat Aug 5 18:59:15 MET DST 1995: Martin Schulze * Now no messages that were received from any remote host are sent * out to another. At my domain this missing feature caused ugly * syslog-loops, sometimes. * * Remember that no message is sent out. I can't figure out any * scenario where it might be useful to change this behavior and to * send out messages to other hosts than the one from which we * received the message, but I might be shortsighted. :-/ * * Thu Aug 10 19:01:08 MET DST 1995: Martin Schulze * Added my pidfile.[ch] to it to perform a better handling with * pidfiles. Now both, syslogd and klogd, can only be started * once. They check the pidfile. * * Sun Aug 13 19:01:41 MET DST 1995: Martin Schulze * Add an addition to syslog.conf's interpretation. If a priority * begins with an exclamation mark ('!') the normal interpretation * of the priority is inverted: ".!*" is the same as ".none", ".!=info" * don't logs the info priority, ".!crit" won't log any message with * the priority crit or higher. For example: * * mail.*;mail.!=info /usr/adm/mail * * Would log all messages of the facility mail except those with * the priority info to /usr/adm/mail. This makes the syslogd * much more flexible. * * Defined TABLE_ALLPRI=255 and changed some occurrences. * * Sat Aug 19 21:40:13 MET DST 1995: Martin Schulze * Making the table of facilities and priorities while in debug * mode more readable. * * If debugging is turned on, printing the whole table of * facilities and priorities every hexadecimal or 'X' entry is * now 2 characters wide. * * The number of the entry is prepended to each line of * facilities and priorities, and F_UNUSED lines are not shown * anymore. * * Corrected some #ifdef SYSV's. * * Mon Aug 21 22:10:35 MET DST 1995: Martin Schulze * Corrected a strange behavior during parsing of configuration * file. The original BSD syslogd doesn't understand spaces as * separators between specifier and action. This syslogd now * understands them. The old behavior caused some confusion over * the Linux community. * * Thu Oct 19 00:02:07 MET 1995: Martin Schulze * The default behavior has changed for security reasons. The * syslogd will not receive any remote message unless you turn * reception on with the "-r" option. * * Not defining SYSLOG_INET will result in not doing any network * activity, i.e. not sending or receiving messages. I changed * this because the old idea is implemented with the "-r" option * and the old thing didn't work anyway. * * Thu Oct 26 13:14:06 MET 1995: Martin Schulze * Added another logfile type F_FORW_UNKN. The problem I ran into * was a name server that runs on my machine and a forwarder of * kern.crit to another host. The hosts address can only be * fetched using the nameserver. But named is started after * syslogd, so syslogd complained. * * This logfile type will retry to get the address of the * hostname ten times and then complain. This should be enough to * get the named up and running during boot sequence. * * Fri Oct 27 14:08:15 1995: Dr. Wettstein * Changed static array of logfiles to a dynamic array. This * can grow during process. * * Fri Nov 10 23:08:18 1995: Martin Schulze * Inserted a new tabular sys_h_errlist that contains plain text * for error codes that are returned from the net subsystem and * stored in h_errno. I have also changed some wrong lookups to * sys_errlist. * * Wed Nov 22 22:32:55 1995: Martin Schulze * Added the fabulous strip-domain feature that allows us to * strip off (several) domain names from the fqdn and only log * the simple hostname. This is useful if you're in a LAN that * has a central log server and also different domains. * * I have also also added the -l switch do define hosts as * local. These will get logged with their simple hostname, too. * * Thu Nov 23 19:02:56 MET DST 1995: Martin Schulze * Added the possibility to omit fsyncing of logfiles after every * write. This will give some performance back if you have * programs that log in a very verbose manner (like innd or * smartlist). Thanks to Stephen R. van den Berg * for the idea. * * Thu Jan 18 11:14:36 CST 1996: Dr. Wettstein * Added patche from beta-testers to stop compile error. Also * added removal of pid file as part of termination cleanup. * * Wed Feb 14 12:42:09 CST 1996: Dr. Wettstein * Allowed forwarding of messages received from remote hosts to * be controlled by a command-line switch. Specifying -h allows * forwarding. The default behavior is to disable forwarding of * messages which were received from a remote host. * * Parent process of syslogd does not exit until child process has * finished initialization process. This allows rc.* startup to * pause until syslogd facility is up and operating. * * Re-arranged the select code to move UNIX domain socket accepts * to be processed later. This was a contributed change which * has been proposed to correct the delays sometimes encountered * when syslogd starts up. * * Minor code cleanups. * * Thu May 2 15:15:33 CDT 1996: Dr. Wettstein * Fixed bug in init function which resulted in file descripters * being orphaned when syslogd process was re-initialized with SIGHUP * signal. Thanks to Edvard Tuinder * (Edvard.Tuinder@praseodymium.cistron.nl) for putting me on the * trail of this bug. I am amazed that we didn't catch this one * before now. * * Tue May 14 00:03:35 MET DST 1996: Martin Schulze * Corrected a mistake that causes the syslogd to stop logging at * some virtual consoles under Linux. This was caused by checking * the wrong error code. Thanks to Michael Nonweiler * for sending me a patch. * * Mon May 20 13:29:32 MET DST 1996: Miquel van Smoorenburg * Added continuation line supported and fixed a bug in * the init() code. * * Tue May 28 00:58:45 MET DST 1996: Martin Schulze * Corrected behaviour of blocking pipes - i.e. the whole system * hung. Michael Nonweiler has sent us * a patch to correct this. A new logfile type F_PIPE has been * introduced. * * Mon Feb 3 10:12:15 MET DST 1997: Martin Schulze * Corrected behaviour of logfiles if the file can't be opened. * There was a bug that causes syslogd to try to log into non * existing files which ate cpu power. * * Sun Feb 9 03:22:12 MET DST 1997: Martin Schulze * Modified syslogd.c to not kill itself which confuses bash 2.0. * * Mon Feb 10 00:09:11 MET DST 1997: Martin Schulze * Improved debug code to decode the numeric facility/priority * pair into textual information. * * Tue Jun 10 12:35:10 MET DST 1997: Martin Schulze * Corrected freeing of logfiles. Thanks to Jos Vos * for reporting the bug and sending an idea to fix the problem. * * Tue Jun 10 12:51:41 MET DST 1997: Martin Schulze * Removed sleep(10) from parent process. This has caused a slow * startup in former times - and I don't see any reason for this. * * Sun Jun 15 16:23:29 MET DST 1997: Michael Alan Dorman * Some more glibc patches made by . * * Thu Jan 1 16:04:52 CET 1998: Martin Schulze . * This included some balance parentheses for emacs and a bug in * the exclamation mark handling. * * Fixed small bug which caused syslogd to write messages to the * wrong logfile under some very rare conditions. Thanks to * Herbert Xu for fiddling this out. * * Thu Jan 8 22:46:35 CET 1998: Martin Schulze * Reworked one line of the above patch as it prevented syslogd * from binding the socket with the result that no messages were * forwarded to other hosts. * * Sat Jan 10 01:33:06 CET 1998: Martin Schulze * Fixed small bugs in F_FORW_UNKN meachanism. Thanks to Torsten * Neumann for pointing me to it. * * Mon Jan 12 19:50:58 CET 1998: Martin Schulze * Modified debug output concerning remote receiption. * * Mon Feb 23 23:32:35 CET 1998: Topi Miettinen * Re-worked handling of Unix and UDP sockets to support closing / * opening of them in order to have it open only if it is needed * either for forwarding to a remote host or by receiption from * the network. * * Wed Feb 25 10:54:09 CET 1998: Martin Schulze * Fixed little comparison mistake that prevented the MARK * feature to work properly. * * Wed Feb 25 13:21:44 CET 1998: Martin Schulze * Corrected Topi's patch as it prevented forwarding during * startup due to an unknown LogPort. * * Sat Oct 10 20:01:48 CEST 1998: Martin Schulze * Added support for TESTING define which will turn syslogd into * stdio-mode used for debugging. * * Sun Oct 11 20:16:59 CEST 1998: Martin Schulze * Reworked the initialization/fork code. Now the parent * process activates a signal handler which the daughter process * will raise if it is initialized. Only after that one the * parent process may exit. Otherwise klogd might try to flush * its log cache while syslogd can't receive the messages yet. * * Mon Oct 12 13:30:35 CEST 1998: Martin Schulze * Redirected some error output with regard to argument parsing to * stderr. * * Mon Oct 12 14:02:51 CEST 1998: Martin Schulze * Applied patch provided vom Topi Miettinen with regard to the * people from OpenBSD. This provides the additional '-a' * argument used for specifying additional UNIX domain sockets to * listen to. This is been used with chroot()'ed named's for * example. See for http://www.psionic.com/papers/dns.html * * Mon Oct 12 18:29:44 CEST 1998: Martin Schulze * Added `ftp' facility which was introduced in glibc version 2. * It's #ifdef'ed so won't harm with older libraries. * * Mon Oct 12 19:59:21 MET DST 1998: Martin Schulze * Code cleanups with regard to bsd -> posix transition and * stronger security (buffer length checking). Thanks to Topi * Miettinen * . index() --> strchr() * . sprintf() --> snprintf() * . bcopy() --> memcpy() * . bzero() --> memset() * . UNAMESZ --> UT_NAMESIZE * . sys_errlist --> strerror() * * Mon Oct 12 20:22:59 CEST 1998: Martin Schulze * Added support for setutent()/getutent()/endutend() instead of * binary reading the UTMP file. This is the the most portable * way. This allows /var/run/utmp format to change, even to a * real database or utmp daemon. Also if utmp file locking is * implemented in libc, syslog will use it immediately. Thanks * to Topi Miettinen . * * Mon Oct 12 20:49:18 MET DST 1998: Martin Schulze * Avoid logging of SIGCHLD when syslogd is in the process of * exiting and closing its files. Again thanks to Topi. * * Mon Oct 12 22:18:34 CEST 1998: Martin Schulze * Modified printline() to support 8bit characters - such as * russion letters. Thanks to Vladas Lapinskas . * * Sat Nov 14 02:29:37 CET 1998: Martin Schulze * ``-m 0'' now turns of MARK logging entirely. * * Tue Jan 19 01:04:18 MET 1999: Martin Schulze * Finally fixed an error with `-a' processing, thanks to Topi * Miettinen . * * Sun May 23 10:08:53 CEST 1999: Martin Schulze * Removed superflous call to utmpname(). The path to the utmp * file is defined in the used libc and should not be hardcoded * into the syslogd binary referring the system it was compiled on. * * Sun Sep 17 20:45:33 CEST 2000: Martin Schulze * Fixed some bugs in printline() code that did not escape * control characters '\177' through '\237' and contained a * single-byte buffer overflow. Thanks to Solar Designer * . * * Sun Sep 17 21:26:16 CEST 2000: Martin Schulze * Don't close open sockets upon reload. Thanks to Bill * Nottingham. * * Mon Sep 18 09:10:47 CEST 2000: Martin Schulze * Fixed bug in printchopped() that caused syslogd to emit * kern.emerg messages when splitting long lines. Thanks to * Daniel Jacobowitz for the fix. * * Mon Sep 18 15:33:26 CEST 2000: Martin Schulze * Removed unixm/unix domain sockets and switch to Datagram Unix * Sockets. This should remove one possibility to play DoS with * syslogd. Thanks to Olaf Kirch for the patch. * * Sun Mar 11 20:23:44 CET 2001: Martin Schulze * Don't return a closed fd if `-a' is called with a wrong path. * Thanks to Bill Nottingham for providing * a patch. rsyslog-7.4.4/COPYING.ASL200000664000175000017500000002166111736765142012010 00000000000000Apache License Version 2.0, January 2004 http://www.apache.org/licenses/ TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION 1.

Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. HP-UX `make' updates targets which have the same time stamps as their prerequisites, which makes it generally unusable when shipped generated files such as `configure' are involved. Use GNU `make' instead. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. rsyslog-7.4.4/compat/0000775000175000017500000000000012211342071011507 500000000000000rsyslog-7.4.4/compat/ifaddrs.h0000775000175000017500000000540212210144261013220 00000000000000#include "config.h" #ifndef HAVE_GETIFADDRS /* * CDDL HEADER START * * The contents of this file are subject to the terms of the * Common Development and Distribution License (the "License"). * You may not use this file except in compliance with the License. * * You can obtain a copy of the license at usr/src/OPENSOLARIS.LICENSE * or http://www.opensolaris.org/os/licensing. * See the License for the specific language governing permissions * and limitations under the License. * * When distributing Covered Code, include this CDDL HEADER in each * file and include the License file at usr/src/OPENSOLARIS.LICENSE. * If applicable, add the following below this CDDL HEADER, with the * fields enclosed by brackets "[]" replaced with your own identifying * information: Portions Copyright [yyyy] [name of copyright owner] * * CDDL HEADER END */ /* * Copyright (c) 2010, Oracle and/or its affiliates.

User Message Output Module

Module Name:    omusrmsg

Author: Rainer Gerhards <rgergards@adiscon.com>

Description:

The omusrmsg plug-in provides the core functionality for logging output to a logged on user. It is a built-in module that does not need to be loaded.

 

Global Configuration Directives:

  • Template [templateName]
    sets a new default template for file actions.

 

Action specific Configuration Directives:

  • Users string
    Must be a valid user name or root.

Caveats/Known Bugs:

  • None.

Sample:

The following command sends all critical syslog messages to a user and to root.



Legacy Configuration Directives:

No specific configuration directives available. See configuration sample below for details on using the plugin.

Legacy Sample:

The following command sends all critical syslog messages to a user and to root.

$FileCreateMode

Type: global configuration directive

Default: 0644

Description:

The $FileCreateMode directive allows to specify the creation mode with which rsyslogd creates new files. If not specified, the value 0644 is used (which retains backward-compatibility with earlier releases). The value given must always be a 4-digit octal number, with the initial digit being zero.

Please note that the actual permission depend on rsyslogd's process umask. If in doubt, use "$umask 0000" right at the beginning of the configuration file to remove any restrictions.

$FileCreateMode may be specified multiple times. If so, it specifies the creation mode for all selector lines that follow until the next $FileCreateMode directive. Order of lines is vitally important.

Sample:

$FileCreateMode 0600

This sample lets rsyslog create files with read and write access only for the users it runs under.

The following sample is deemed to be a complete rsyslog.conf:

$umask 0000 # make sure nothing interferes with the following definitions
*.* /var/log/file-with-0644-default
$FileCreateMode 0600
*.* /var/log/file-with-0600
$FileCreateMode 0644
*.* /var/log/file-with-0644

As you can see, open modes depend on position in the config file. Note the first line, which is created with the hardcoded default creation mode.

rsyslog.conf configuration file

Rsyslog is configured via the rsyslog.conf file, typically found in /etc. By default, rsyslogd reads the file /etc/rsyslog.conf. This may be changed by command line option "-f".

Configuration file examples can be found in the rsyslog wiki. Also keep the rsyslog config snippets on your mind. These are ready-to-use real building blocks for rsyslog configuration.

While rsyslogd contains enhancements over standard syslogd, efforts have been made to keep the configuration file as compatible as possible. While, for obvious reasons, enhanced features require a different config file syntax, rsyslogd should be able to work with a standard syslog.conf file. This is especially useful while you are migrating from syslogd to rsyslogd.

Reliable Forwarding of syslog Messages with Rsyslog

Written by Rainer Gerhards (2008-06-27)

Abstract

In this paper, I describe how to forward syslog messages (quite) reliable to a central rsyslog server. This depends on rsyslog being installed on the client system and it is recommended to have it installed on the server system. Please note that industry-standard plain TCP syslog protocol is not fully reliable (thus the "quite reliable"). If you need a truely reliable solution, you need to look into RELP (natively supported by rsyslog).

The Intention

Whenever two systems talk over a network, something can go wrong. For example, the communications link may go down, or a client or server may abort. Even in regular cases, the server may be offline for a short period of time because of routine maintenance.

A logging system should be capable of avoiding message loss in situations where the server is not reachable. To do so, unsent data needs to be buffered at the client while the server is offline. Then, once the server is up again, this data is to be sent.

This can easily be acomplished by rsyslog. In rsyslog, every action runs on its own queue and each queue can be set to buffer data if the action is not ready. Of course, you must be able to detect that "the action is not ready", which means the remote server is offline. This can be detected with plain TCP syslog and RELP, but not with UDP. So you need to use either of the two. In this howto, we use plain TCP syslog.

Please note that we are using rsyslog-specific features. The are required on the client, but not on the server. So the client system must run rsyslog (at least version 3.12.0), while on the server another syslogd may be running, as long as it supports plain tcp syslog.

The rsyslog queueing subsystem tries to buffer to memory. So even if the remote server goes offline, no disk file is generated. File on disk are created only if there is need to, for example if rsyslog runs out of (configured) memory queue space or needs to shutdown (and thus persist yet unsent messages). Using main memory and going to the disk when needed is a huge performance benefit. You do not need to care about it, because, all of it is handled automatically and transparently by rsyslog.

How To Setup

First, you need to create a working directory for rsyslog. This is where it stores its queue files (should need arise). You may use any location on your local system.

Next, you need to do is instruct rsyslog to use a disk queue and then configure your action. There is nothing else to do. With the following simple config file, you forward anything you receive to a remote server and have buffering applied automatically when it goes down. This must be done on the client machine.

The port given above is optional. It may not be specified, in which case you only provide the server name. The "$ActionQueueFileName" is used to create queue files, should need arise. This value must be unique inside rsyslog.conf. No two rules must use the same queue file. Also, for obvious reasons, it must only contain those characters that can be used inside a valid file name. Rsyslog possibly adds some characters in front and/or at the end of that name when it creates files. So that name should not be at the file size name length limit (which should not be a problem these days).

Please note that actual spool files are only created if the remote server is down and there is no more space in the in-memory queue. By default, a short failure of the remote server will never result in the creation of a disk file as a couple of hundered messages can be held in memory by default. [These parameters can be fine-tuned. However, then you need to either fully understand how the queue works (read elaborate doc) or use professional services to have it done based on your specs ;) - what that means is that fine-tuning queue parameters is far from being trivial...]

If you would like to test if your buffering scenario works, you need to stop, wait a while and restart you central server. Do not watch for files being created, as this usually does not happen and never happens immediately.

Forwarding to More than One Server

If you have more than one server you would like to forward to, that's quickly done. Rsyslog has no limit on the number or type of actions, so you can define as many targets as you like. What is important to know, however, is that the full set of directives make up an action. So you can not simply add (just) a second forwarding rule, but need to duplicate the rule configuration as well. Be careful that you use different queue file names for the second action, else you will mess up your system.

A sample for forwarding to two hosts looks like this:

Note the filename used for the first rule it is "srvrfwd1" and for the second it is "srvrfwd2". I have used a server without port name in the second forwarding rule. This was just to illustrate how this can be done. You can also specify a port there (or drop the port from server1).

When there are multiple action queues, they all work independently. Thus, if server1 goes down, server2 still receives data in real-time. The client will not block and wait for server1 to come back online. Similarily, server1's operation will not be affected by server2's state.

Some Final Words on Reliability ...

Using plain TCP syslog provides a lot of reliability over UDP syslog. However, plain TCP syslog is not a fully reliable transport. In order to get full reliability, you need to use the RELP protocol.

Compatibility Notes for rsyslog v6

Written by Rainer Gerhards (2011-10-27)

This document describes things to keep in mind when moving from v5 to v6. It does not list enhancements nor does it talk about compatibility concerns introduced by earlier versions (for this, see their respective compatibility documents). Its focus is primarily on what you need to know if you used a previous version and want to use the current one without hassle.

Version 6 offers a better config language and some other improvements. As the config system has many ties into the rsyslog engine AND all plugins, the changes are somewhat intrusive. Note, however, that core processing has not been changed much in v6 and will not. So once the configuration is loaded, the stability of v6 is quite comparable to v5.

Property "pri-text"

Traditionally, this property did not only return the textual form of the pri ("local0.err"), but also appended the numerical value to it ("local0.err<133>"). This sounds odd and was left unnoticed for some years. In October 2011, this odd behaviour was brought up on the rsyslog mailing list by Gregory K. Ruiz-Ade. Code review showed that the behaviour was intentional, but no trace of what the intention was when it was introduced could be found. The documentation was also unclear, it said no numerical value was present, but the samples had it. We agreed that the additional numerical value is of disadvantage. We also guessed that this property is very rarely being used, otherwise the problem should have been raised much earlier. However, we didn't want to change behaviour in older builds. So v6 was set to clean up the situation. In v6, text-pri will always return the textual part only ("local0.err") and the numerical value will not be contained any longer inside the string. If you actually need that value, it can fairly easily be added via the template system.

If you have used this property previously and relied on the numerical part, you need to update your rsyslog configuration files.

Plugin ABI

The plugin interface has considerably been changed to support the new config language. All plugins need to be upgraded. This usually does not require much coding. However, if the new config language shall be supported, more changes must be made to plugin code. All project-supported plugins have been upgraded, so this compatibility issue is only of interest for you if you have custom plugins or use some user-contributed plugins from the rsyslog project that are not maintained by the project itself (omoracle is an example). Please expect some further plugin instablity during the initial v6 releases.

RainerScript based rsyslog.conf

A better config format was the main release target for rsyslog v6. It comes in the flavor of so-called RainerScript (why the name RainerScript?). RainerScript supports legacy syslog.conf format, much as you know it from other syslogd's (like sysklogd or the BSD syslogd's) as well as previous versions of rsyslog. Initial work on RainerScript began in v4, and the if-construct was already supported in v4 and v5. Version 6 has now taken this further. After long discussions we decided to use the legacy format as a basis, and lightly extend it by native RainerScript constructs. The main goal was to make sure that previous knowledge and config systems could still be used while offering a much more intuitive and powerful way of configuring rsyslog.

RainerScript has been implemented from scratch and with new tools (flex/bison, for those in the know). Starting with 6.3.3, this new config file processor replaces the legacy one. Note that the new processor handles all formats, extended RainerScript as well as legacy syslog.conf format. There are some legacy construct that were especially hard to translate. You'll read about them in other parts of this document (especially outchannels, which require a format change).

In v6, all legacy formats are supported. In the long term, we may remove some of the ugly rsyslog-specific constructs. Good candidates are all configuration commands starting with a dollar sign, like "$ActionFileDefaultTemplate"). However, this will not be the case before rsyslog v7 or (much more likely) v8/9. Right now, you also need to use these commands, because not all have already been converted to the new RainerScript format.

In 6.3.3, the new parser is used, but almost none of the extended RainerScript capabilities are available. They will incrementally be introduced with the following releases. Note that for some features (most importantly if-then-else nested blocks), the v6 core engine is not capable enough. It is our aim to provide a much better config language to as many rsyslog users as quickly as possible. As such, we refrain from doing big engine changes in v6. This in turn means we cannot introduce some features into RainerScript that we really want to see. These features will come up with rsyslog v7, which will have even better flow control capabilities inside the core engine. Note that v7 will fully support v6 RainerScript. Let us also say that the v6 version is not a low-end quick hack: it offers full-fledged syslog message processing control, capable of doing the best you can find inside the industry. We just say that v7 will come up with even more advanced capabilites.

Please note that we tried hard to make the RainerScript parser compatible with all legacy config files. However, we may have failed in one case or another. So if you experience problems during config processing, chances are there may be a problem on the rsyslog side. In that case, please let us know.

Please see the blog post about rsyslog 6.3.3 config format for details of what is currently supported.

compatibility mode

Compatibility mode (specified via -c option) has been removed. This was a migration aid from sysklogd and very early versions of rsyslog. As all major distros now have rsyslog as their default, and thus ship rsyslog-compliant config files, there is no longer a need for compatibility mode. Removing it provides easier to maintain code. Also, practice has shown that many users were confused by compatibility mode (and even some package maintainers got it wrong). So this not only cleans up the code but rather removes a frequent source of error.

It must be noted, though, that this means rsyslog is no longer a 100% drop-in replacement for sysklogd. If you convert an extremely old system, you need to checks its config and probably need to apply some very mild changes to the config file.

abort on config errors

Previous versions accepted some malformedness inside the config file without aborting. This could lead to some uncertainty about which configuration was actually running. In v6 there are some situations where config file errors can not be ignored. In these cases rsyslog emits error messages to stderr, and then exists with a non-zero exit code. It is important to check for those cases as this means log data is potentially lost. Please note that the root problem is the same for earlier versions as well. With them, it was just harder to spot why things went wrong (and if at all).

Default Batch Sizes

Due to their positive effect on performance and comparatively low overhead, default batch sizes have been increased. Starting with 6.3.4, the action queues have a default batch size of 128 messages.

Default action queue enqueue timeout

This timeout previously was 2seconds, and has been reduced to 50ms (starting with 6.5.0). This change was made as a long timeout will caused delays in the associated main queue, something that was quite unexpected to users. Now, this can still happen, but the effect is much less harsh (but still considerable on a busy system). Also, 50ms should be fairly enough for most output sources, except when they are really broken (like network disconnect). If they are really broken, even a 2second timeout does not help, so we hopefully get the best of both worlds with the new timeout. A specific timeout can of course still be configured, it is just the timeout that changed.

outchannels

Outchannels are a to-be-removed feature of rsyslog, at least as far as the config syntax is concerned. Nevertheless, v6 still supports it, but a new syntax is required for the action. Let's assume your outchannel is named "channel". The previous syntax was

*.* $channel
This was deprecated in v5 and no longer works in v6. Instead, you need to specify
*.* :omfile:$channel
Note that this syntax is available starting with rsyslog v4. It is important to keep on your mind that future versions of rsyslog will require different syntax and/or drop outchannel support completely. So if at all possible, avoid using this feature. If you must use it, be prepared for future changes and watch announcements very carefully.

Starting with 6.5.0, ompipe does no longer use the omfile default template. Instead, the default template must be set via the module load statement. An example is

module(load="builtin:ompipe" template="myDefaultTemplate")

For obvious reasons, the default template must be defined somewhere in the config file, otherwise errors will happen during the config load phase.

omusrmsg

The omusrmsg module is used to send messages to users. In legacy-legacy config format (that is the very old sysklogd style), it was suffucient to use just the user name to call this action, like in this example:

*.* rgerhards
This format is very ambigious and causes headache (see blog post on omusrmsg for details). Thus the format has been superseded by this syntax (which is legacy format ;-)):
*.* :omusrmsg:rgerhards
That syntax is supported since later subversions of version 4.

Rsyslog v6 still supports the legacy-legacy format, but in a very strict sense. For example, if multiple users or templates are given, no spaces must be included in the action line. For example, this works up to v5, but no longer in v6:

*.* rgerhards, bgerhards
To fix it in a way that is compatible with pre-v4, use (note the removed space!):
*.* rgerhards,bgerhards
Of course, it probably is better to understand in native v6 format:
*.* action(type="omusrmsg" users="rgerhards, bgerhards")
As you see, here you may include spaces between user names.

In the long term, legacy-legacy format will most probably totally disappear, so it is a wise decision to change config files at least to the legacy format (with ":omusrmsg:" in front of the name).

Escape Sequences in Script-Based Filters

In v5, escape sequences were very simplistic. Inside a string, "\x" meant "x" with x being any character. This has been changed so that the usual set of escapes is supported, must importantly "\n", "\t", "\xhh" (with hh being hex digits) and "\ooo" with (o being octal digits). So if one of these sequences was used previously, results are obviously different. However, that should not create any real problems, because it is hard to envision why someone should have done that (why write "\n" when you can also write "n"?).

HOWTO install rsyslog

Written by Rainer Gerhards

Abstract

In this paper, I describe how to install rsyslog. It is intentionally a brief step-by-step guide, targeted to those who want to quickly get it up and running. For more elaborate information, please consult the rest of the manual set.

How to make your life easier...

Some folks have thankfully created RPMs/packages for rsyslog. If you use them, you can spare yourself many of the steps below. This is highly recommended if there is a package for your distribution available.

Steps To Do

Rsyslog does currently only have very limited availability as a package (if you volunteer to create one, drop me a line). Thus, this guide focuses on installing from the source, which thankfully is quite easy.

Step 1 - Download Software

For obvious reasons, you need to download rsyslog. Here, I assume that you use a distribution tarball. If you would like to use a version directly from the repository, see build rsyslog from repository instead.

Load the most recent build from http://www.rsyslog.com/downloads. Extract the software with "tar xzf -nameOfDownloadSet-". This will create a new subdirectory rsyslog-version in the current working directory. CD into that.

Depending on your system configuration, you also need to install some build tools, most importantly make, the gcc compiler and the MySQL development system (if you intend to use MySQL - the package is often named "mysql-dev"). On many systems, these things should already be present. If you don't know exactly, simply skip this step for now and see if nice error messages pop up during the compile process. If they do, you can still install the missing build environment tools. So this is nothing that you need to look at very carefully.

Step 2 - Run ./configure

Run ./configure to adopt rsyslog to your environment. While doing so, you can also enable options. Configure will display selected options when it is finished. For example, to enable MySQL support, run

./configure --enable-mysql

Please note that MySQL support by default is NOT disabled.

Step 3 - Compile

That is easy. Just type "make" and let the compiler work. On any recent system, that should be a very quick task, on many systems just a matter of a few seconds. If an error message comes up, most probably a part of your build environment is not installed. Check with step 1 in those cases.

Step 4 - Install

Again, that is quite easy. All it takes is a "make install". That will copy the rsyslogd and the man pages to the relevant directories.

Step 5 - Configure rsyslogd

In this step, you tell rsyslogd what to do with received messages. If you are upgrading from stock syslogd, /etc/syslog.conf is probably a good starting point. Rsyslogd understands stock syslogd syntax, so you can simply copy over /etc/syslog.conf to /etc/rsyslog.conf. Note since version 3 rsyslog requires to load plug-in modules to perform useful work (more about compatibilty notes v3). To load the most common plug-ins, add the following to the top of rsyslog.conf:

$ModLoad immark # provides --MARK-- message capability
$ModLoad imudp # provides UDP syslog reception
$ModLoad imtcp # provides TCP syslog reception and GSS-API (if compiled to support it)
$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
$ModLoad imklog # provides kernel logging support (previously done by rklogd)

Change rsyslog.conf for any further enhancements you would like to see. For example, you can add database writing as outlined in the paper "Writing syslog Data to MySQL" (remember you need to enable MySQL support during step 2 if you want to do that!).

Step 6 - Disable stock syslogd

In almost all cases, there already is stock syslogd installed. Because both it and rsyslogd listen to the same sockets, they can NOT be run concurrently. So you need to disable the stock syslogd. To do this, you typically must change your rc.d startup scripts.

For example, under Debian this must be done as follows: The default runlevel is 2. We modify the init scripts for runlevel 2 - in practice, you need to do this for all run levels you will ever use (which probably means all). Under /etc/rc2.d there is a S10sysklogd script (actually a symlink). Change the name to _S10sysklogd (this keeps the symlink in place, but will prevent further execution - effectively disabling it).

Step 7 - Enable rsyslogd Autostart

This step is very close to step 3. Now, we want to enable rsyslogd to start automatically. The rsyslog package contains a (currently small) number of startup scripts. They are inside the distro-specific directory (e.g. debian). If there is nothing for your operating system, you can simply copy the stock syslogd startup script and make the minor modifications to run rsyslogd (the samples should be of help if you intend to do this).

In our Debian example, the actual scripts are stored in /etc/init.d. Copy the standard script to that location. Then, you need to add a symlink to it in the respective rc.d directory. In our sample, we modify rc2.d, and can do this via the command "ln -s ../init.d/rsyslogd S10rsyslogd". Please note that the S10 prefix tells the system to start rsyslogd at the same time stock sysklogd was started.

Important: if you use the database functionality, you should make sure that MySQL starts before rsyslogd. If it starts later, you will receive an error message during each restart (this might be acceptable to you). To do so, either move MySQL's start order before rsyslogd or rsyslogd's after MySQL.

Step 8 - Check daily cron scripts

Most distributions come pre-configured with some daily scripts for log rotation. As long as you use the same log file names, the log rotation scripts will probably work quite well. There is one caveat, though. The scripts need to tell syslogd that the files have been rotated. To do this, they typically have a part using syslogd's init script to do that. Obviously, the default scripts do not know about rsyslogd, so they manipulate syslogd. If that happens, in most cases an additional instance of stock syslogd is started (in almost all cases, this was not functional, but it is at least distracting). It also means that rsyslogd is not properly told about the log rotation, which will lead it to continue to write to the now-rotated files.

So you need to fix these scripts. See your distro-specific documentation how they are located. Under most Linuxes, the primary script to modify is /etc/cron.daily/sysklogd. Watch for a comment "Restart syslogd" (usually at the very end of the file). The restart command must be changed to use rsyslogd's rc script.

Also, if you use klogd together with rsyslogd (under most Linuxes you will do that), you need to make sure that klogd is restarted after rsyslogd is restarted. So it might be a good idea to put a klogd reload-or-restart command right after the rsyslogd command in your daily script. This can save you lots of troubles.

Done

This concludes the steps necessary to install rsyslogd. Of course, it is always a good idea to test everything thoroughly. At a minimalist level, you should do a reboot and after that check if everything has come up correctly. Pay attention not only to running processes, but also check if the log files (or the database) are correctly being populated.

If rsyslogd encounters any serious errors during startup, you should be able to see them at least on the system console. They might not be in log file, as errors might occur before the log file rules are in place. So it is always a good idea to check system console output when things don't go smooth. In some rare cases, enabling debug logging (-d option) in rsyslogd can be helpful. If all fails, go to www.rsyslog.com and check the forum or mailing list for help with your issue.

Housekeeping stuff

This section and its subsections contain all these nice things that you usually need to read only if you are really curios ;)

Feedback requested

$AboortOnUncleanConfig

Type: global configuration directive

Parameter Values: boolean (on/off, yes/no)

Available since: 5.3.1+

Default: off

Description:

This directive permits to prevent rsyslog from running when the configuration file is not clean. "Not Clean" means there are errors or some other annoyances that rsyslgod reports on startup. This is a user-requested feature to have a strict startup mode. Note that with the current code base it is not always possible to differentiate between an real error and a warning-like condition. As such, the startup will also prevented if warnings are present. I consider this a good thing in being "strict", but I admit there also currently is no other way of doing it.

Caveats:

Note that the consequences of a failed rsyslogd startup can be much more serious than a startup with only partial configuration. For example, log data may be lost or systems that depend on the log server in question will not be able to send logs, what in the ultimate result could result in a system hang on those systems. Also, the local system may hang when the local log socket has become full and is not read. There exist many such scenarios. As such, it is strongly recommended not to turn on this directive.

RainerScript

RainerScript is a scripting language specifically designed and well-suited for processing network events and configuring event processors (with the most prominent sample being syslog). While RainerScript is theoritically usable with various softwares, it currently is being used, and developed for, rsyslog. Please note that RainerScript may not be abreviated as rscript, because that's somebody elses trademark.

RainerScript is currently under development. It has its first appearance in rsyslog 3.12.0, where it provides complex expression support. However, this is only a very partial implementatio of the scripting language. Due to technical restrictions, the final implementation will have a slightly different syntax. So while you are invited to use the full power of expresssions, you unfortunatley need to be prepared to change your configuration files at some later points. Maintaining backwards-compatibility at this point would cause us to make too much compromise. Defering the release until everything is perfect is also not a good option. So use your own judgement.

A formal definition of the language can be found in RainerScript ABNF. The rest of this document describes the language from the user's point of view. Please note that this doc is also currently under development and can (and will) probably improve as time progresses. If you have questions, use the rsyslog forum. Feedback is also always welcome.

Data Types

RainerScript is a typeless language. That doesn't imply you don't need to care about types. Of course, expressions like "A" + "B" will not return a valid result, as you can't really add two letters (to concatenate them, use the concatenation operator &).  However, all type conversions are automatically done by the script interpreter when there is need to do so.

Expressions

The language supports arbitrary complex expressions. All usual operators are supported. The precedence of operations is as follows (with operations being higher in the list being carried out before those lower in the list, e.g. multiplications are done before additions.
  • expressions in parenthesis
  • not, unary minus
  • *, /, % (modulus, as in C)
  • +, -, & (string concatenation)
  • ==, !=, <>, <, >, <=, >=, contains (strings!), startswith (strings!)
  • and
  • or
For example, "not a == b" probably returns not what you intended. The script processor will first evaluate "not a" and then compare the resulting boolean to the value of b. What you probably intended to do is "not (a == b)". And if you just want to test for inequality, we highly suggest to use "!=" or "<>". Both are exactly the same and are provided so that you can pick whichever you like best. So inquality of a and b should be tested as "a <> b". The "not" operator should be reserved to cases where it actually is needed to form a complex boolean expression. In those cases, parenthesis are highly recommended.

Lookup Tables

Lookup tables are a powerful construct to obtain "class" information based on message content (e.g. to build log file names for different server types, departments or remote offices).

Functions

RainerScript supports a currently quite limited set of functions:

  • getenv(str) - like the OS call, returns the value of the environment variable, if it exists. Returns an empty string if it does not exist.
  • strlen(str) - returns the length of the provided string
  • tolower(str) - converts the provided string into lowercase
  • cstr(expr) - converts expr to a string value
  • cnum(expr) - converts expr to a number (integer)
  • re_match(expr, re) - returns 1, if expr matches re, 0 otherwise
  • re_extract(expr, re, match, submatch, no-found) - extracts data from a string (property) via a regular expression match. POSIX ERE regular expressions are used. The variable "match" contains the number of the match to use. This permits to pick up more than the first expression match. Submatch is the submatch to match (max 50 supported). The "no-found" parameter specifies which string is to be returned in case when the regular expression is not found. Note that match and submatch start with zero. It currently is not possible to extract more than one submatch with a single call.
  • field(str, delim, matchnbr) - returns a field-based substring. str is the string to search, delim is the delimiter and matchnbr is the match to search for (the first match starts at 1). This works similar as the field based property-replacer option. Versions prior to 7.3.7 only support a single character as delimiter character. Starting with version 7.3.7, a full string can be used as delimiter. If a single character is being used as delimiter, delim is the numerical ascii value of the field delimiter character (so that non-printable characters can by specified). If a string is used as delmiter, a multi-character string (e.g. "#011") is to be specified. Samples:
    set $!usr!field = field($msg, 32, 3); -- the third field, delimited by space
    set $!usr!field = field($msg, "#011", 3); -- the third field, delmited by "#011"
    Note that when a single character is specified as string [field($msg, ",", 3)] a string-based extraction is done, which is more performance intense than the equivalent single-character [field($msg, 44 ,3)] extraction.
  • prifilt(constant) - mimics a traditional PRI-based filter (like "*.*" or "mail.info"). The traditional filter string must be given as a constant string. Dynamic string evaluation is not permitted (for performance reasons).

The following example can be used to build a dynamic filter based on some environment variable: 

if $msg contains getenv('TRIGGERVAR') then /path/to/errfile

Input Module to Generate Periodic Statistics of Internal Counters

Module Name:    impstats

Available since: 5.7.0+, 6.1.1+

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module provides periodic output of rsyslog internal counters. Note that the whole statistics system is currently under development. So availabilty and format of counters may change and is not yet stable (so be prepared to change your trending scripts when you upgrade to a newer rsyslog version).

The set of available counters will be output as a set of syslog messages. This output is periodic, with the interval being configurable (default is 5 minutes). Be sure that your configuration records the counter messages (default is syslog.=info). Besides logging to the regular syslog stream, the module can also be configured to write statistics data into a (local) file.

Note that loading this module has impact on rsyslog performance. Depending on settings, this impact may be noticable (for high-load environments).

The rsyslog website has an updated overview of available rsyslog statistic counters.

Module Confguration Parameters:

This module supports module parameters, only.

  • interval [seconds] (default 300 [5minutes])
    Sets the interval, in seconds at which messages are generated. Please note that the actual interval may be a bit longer. We do not try to be precise and so the interval is actually a sleep period which is entered after generating all messages. So the actual interval is what is configured here plus the actual time required to generate messages. In general, the difference should not really matter.
  • facility [templateName]
    The numerical syslog facility code to be used for generated messages. Default is 5 (syslog). This is useful for filtering messages.
  • severity [templateName]
    The numerical syslog severity code to be used for generated messages. Default is 6 (info).This is useful for filtering messages.
  • format [json/cee/legacy](rsyslog v6.3.8+ only)
    Specifies the format of emitted stats messages. The default of "legacy" is compatible with pre v6-rsyslog. The other options provide support for structured formats (note the "cee" is actually "project lumberack" logging).
  • log.syslog [on/off] - available since 7.3.6
    This is a boolean setting specifying if data should be sent to the usual syslog stream. This is useful if custom formatting or more elaborate processing is desired. However, output is placed under the same restrictions as regular syslog data, especially in regard to the queue position (stats data may sit for an extended period of time in queues if they are full).
  • log.file [file name] - available since 7.3.6
    If specified, statistics data is written the specified file. For robustness, this should be a local file. The file format cannot be customized, it consists of a date header, followed by a colon, followed by the actual statistics record, all on one line. Only very limited error handling is done, so if things go wrong stats records will probably be lost. Logging to file an be a useful alternative if for some reasons (e.g. full queues) the regular syslog stream method shall not be used solely. Note that turning on file logging does NOT turn of syslog logging. If that is desired log.syslog="off" must be explicitely set.

Legacx Configuration Directives:

A limited set of parameters can also be set via the legacy configuration syntax. Note that this is intended as an upward compatibilit layer, so newer features are intentionally not available via legacy directives.
  • $PStatInterval <Seconds> - same as the "interval" parameter.
  • $PStatFacility <numerical facility> - same as the "facility" parameter.
  • $PStatSeverity <numerical severity> - same as the "severity" parameter.
  • $PStatJSON <on/off> (rsyslog v6.3.8+ only)
    If set to on, stats messages are emitted as structured cee-enhanced syslog. If set to off, legacy format is used (which is compatible with pre v6-rsyslog).
Caveats/Known Bugs:
  • This module MUST be loaded right at the top of rsyslog.conf, otherwise stats may not get turned on in all places.

Samples:

This activates the module and records messages to /var/log/rsyslog-stats in 10 minute intervals:

Legacy Sample:

This activates the module and records messages to /var/log/rsyslog-stats in 10 minute intervals:

In the next sample, the default interval of 5 minutes is used. However, this time stats data is NOT emitted to the syslog stream but to a local file instead.

And finally, we log to both the regular syslog log stream as well as a file. Within the log stream, we forward the data records to another server:

Kernel Log Input Module

Module Name:    imklog

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

Reads messages from the kernel log and submits them to the syslog engine.

Configuration Directives:

  • LogPath
    The path to the Kernel log. This value should only be changed if you really know what you are doing.
  • InternalMsgFacility <facility>
    The facility which messages internally generated by imklog will have. imklog generates some messages of itself (e.g. on problems, startup and shutdown) and these do not stem from the kernel. Historically, under Linux, these too have "kern" facility. Thus, on Linux platforms the default is "kern" while on others it is "syslogd". You usually do not need to specify this configuratin directive - it is included primarily for few limited cases where it is needed for good reason. Bottom line: if you don't have a good idea why you should use this setting, do not touch it.
  • PermitNonKernelFacility [on/off]
    At least under BSD the kernel log may contain entries with non-kernel facilities. This setting controls how those are handled. The default is "off", in which case these messages are ignored. Switch it to on to submit non-kernel messages to rsyslog processing.
  • ParseKernelTimeStamp [on/off]
    If enabled and the kernel creates a timestamp for its log messages, this timestamp will be parsed and converted into regular message time instead to use the receive time of the kernel message (as in 5.8.x and before). Default is to not parse the kernel timestamp, because the clock used by the kernel to create the timestamps is not supposed to be as accurate as the monotonic clock required to convert it. Depending on the hardware and kernel, it can result in message time differences between kernel and system messages which occurred at same time.
  • KeepKernelTimeStamp [on/off]
    If enabled, this option causes to keep the [timestamp] provided by the kernel at the begin of in each message rather than to remove it, when it could be parsed and converted into local time for use as regular message time. Only used when ParseKernelTimestamp is on.
  • ConsoleLogLevel [number] (former klogd -c option) -- sets the console log level. If specified, only messages with up to the specified level are printed to the console. The default is -1, which means that the current settings are not modified. To get this behavior, do not specify ConsoleLogLevel in the configuration file. Note that this is a global parameter. Each time it is changed, the previous definition is re-set. The one activate will be that one that is active when imklog actually starts processing. In short words: do not specify this directive more than once!
Caveats/Known Bugs:

This is obviously platform specific and requires platform drivers. Currently, imklog functionality is available on Linux and BSD.

This module is not supported on Solaris and not needed there. For Solaris kernel input, use imsolaris.

Sample:

The following sample pulls messages from the kernel log. All parameters are left by default, which is usually a good idea. Please note that loading the plugin is sufficient to activate it. No directive is needed to start pulling kernel messages.

Legacy Configuration Directives:

  • $KLogInternalMsgFacility <facility>
    equivalent to: InternalMsgFacility
  • $KLogPermitNonKernelFacility [on/off]
    equivalent to: PermitNonKernelFacility
  • $DebugPrintKernelSymbols [on/off]
    Linux only, ignored on other platforms (but may be specified)
  • $klogLocalIPIF [interface name] - (available since 5.9.6) - if provided, the IP of the specified interface (e.g. "eth0") shall be used as fromhost-ip for imklog-originating messages. If this directive is not given OR the interface cannot be found (or has no IP address), the default of "127.0.0.1" is used.
  • $klogSymbolLookup [on/off] -- disables imklog kernel symbol translation (former klogd -x option). NOTE that this option is counter-productive on recent kernels (>= 2.6) because the kernel already does the symbol translation and this option breaks the information.
    This option is scheduled for removal, probably with version 4.x. Do not use it except if you have a very good reason. If you have one, let us know because otherwise new versions will no longer support it.
    Linux only, ignored on other platforms (but may be specified)
  • $klogConsoleLogLevel [number]
    equivalent to: ConsoleLogLevel
  • $klogUseSyscallInterface [on/off] -- former klogd -s option
    Linux only, ignored on other platforms (but may be specified)
  • $klogSymbolsTwice [on/off] -- former klogd -2 option
    Linux only, ignored on other platforms (but may be specified)
  • $klogParseKernelTimeStamp [on/off]
    equivalent to: ParseKernelTimeStamp
  • $klogKeepKernelTimeStamp [on/off]
    equivalent to: KeepKernelTimeStamp

Unix Socket Input

Module Name:    imuxsock

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

Provides the ability to accept syslog messages via local Unix sockets. Most importantly, this is the mechanism by which the syslog(3) call delivers syslog messages to rsyslogd. So you need to have this module loaded to read the system log socket and be able to process log messages from applications running on the local system.

Application-provided timestamps are ignored by default. This is needed, as some programs (e.g. sshd) log with inconsistent timezone information, what messes up the local logs (which by default don't even contain time zone information). This seems to be consistent with what sysklogd did for the past four years. Alternate behaviour may be desirable if gateway-like processes send messages via the local log slot - in this case, it can be enabled via the IgnoreTimestamp and SysSock.IgnoreTimestamp config directives

There is input rate limiting available, (since 5.7.1) to guard you against the problems of a wild running logging process. If more than SysSock.RateLimit.Interval * SysSock.RateLimit.Burst log messages are emitted from the same process, those messages with SysSock.RateLimit.Severity or lower will be dropped. It is not possible to recover anything about these messages, but imuxsock will tell you how many it has dropped one the interval has expired AND the next message is logged. Rate-limiting depends on SCM_CREDENTIALS. If the platform does not support this socket option, rate limiting is turned off. If multiple sockets are configured, rate limiting works independently on each of them (that should be what you usually expect). The same functionality is available for additional log sockets, in which case the config statements just use the prefix RateLimit... but otherwise works exactly the same. When working with severities, please keep in mind that higher severity numbers mean lower severity and configure things accordingly. To turn off rate limiting, set the interval to zero.

Unix log sockets can be flow-controlled. That is, if processing queues fill up, the unix socket reader is blocked for a short while. This may be useful to prevent overruning the queues (which may cause exessive disk-io where it actually would not be needed). However, flow-controlling a log socket (and especially the system log socket) can lead to a very unresponsive system. As such, flow control is disabled by default. That means any log records are places as quickly as possible into the processing queues. If you would like to have flow control, you need to enable it via the SysSock.FlowControl and FlowControl config directives. Just make sure you thought about the implications. Note that for many systems, turning on flow control does not hurt.

Starting with rsyslog 5.9.4, trusted syslog properties are available. These require a recent enough Linux Kernel and access to the /proc file system. In other words, this may not work on all platforms and may not work fully when privileges are dropped (depending on how they are dropped). Note that trusted properties can be very useful, but also typically cause the message to grow rather large. Also, the format of log messages is obviously changed by adding the trusted properties at the end. For these reasons, the feature is not enabled by default. If you want to use it, you must turn it on (via SysSock.Annotate and Annotate).

Configuration Directives:

Global Parameters

  • SysSock.IgnoreTimestamp [on/off]
    Ignore timestamps included in the messages, applies to messages received via the system log socket.
  • SysSock.IgnoreOwnMessages [on/off] (available since 7.3.7)
    Ignores messages that originated from the same instance of rsyslogd. There usually is no reason to receive messages from ourselfs. This setting is vital when writing messages to the Linux journal. See omjournal module documentation for a more in-depth description.
  • SysSock.Use (imuxsock) [on/off] do NOT listen for the local log socket. This is most useful if you run multiple instances of rsyslogd where only one shall handle the system log socket.
  • SysSock.Name <name-of-socket>
  • SysSock.FlowControl [on/off] - specifies if flow control should be applied to the system log socket.
  • SysSock.UsePIDFromSystem [on/off] - specifies if the pid being logged shall be obtained from the log socket itself. If so, the TAG part of the message is rewritten. It is recommended to turn this option on, but the default is "off" to keep compatible with earlier versions of rsyslog.
  • SysSock.RateLimit.Interval [number] - specifies the rate-limiting interval in seconds. Default value is 5 seconds. Set it to 0 to turn rate limiting off.
  • SysSock.RateLimit.Burst [number] - specifies the rate-limiting burst in number of messages. Default is 200.
  • SysSock.RateLimit.Severity [numerical severity] - specifies the severity of messages that shall be rate-limited.
  • SysSock.UseSysTimeStamp [on/off] the same as $InputUnixListenSocketUseSysTimeStamp, but for the system log socket.
  • SysSock.Annotate <on/off> turn on annotation/trusted properties for the system log socket.
  • SysSock.ParseTrusted <on/off> if Annotation is turned on, create JSON/lumberjack properties out of the trusted properties (which can be accessed via RainerScript JSON Variables, e.g. "$!pid") instead of adding them to the message.
  • SysSock.Unlink <on/off> (available since 7.3.9)
    if turned on (default), the system socket is unlinked and re-created when opened and also unlinked when finally closed. Note that this setting has no effect when running under systemd control (because systemd handles the socket).

Input Instance Parameters

  • IgnoreTimestamp [on/off]
    Ignore timestamps included in the message. Applies to the next socket being added.
  • IgnoreOwnMessages [on/off] (available since 7.3.7)
    Ignore messages that originated from the same instance of rsyslogd. There usually is no reason to receive messages from ourselfs. This setting is vital when writing messages to the Linux journal. See omjournal module documentation for a more in-depth description.
  • FlowControl [on/off] - specifies if flow control should be applied to the next socket.
  • RateLimit.Interval [number] - specifies the rate-limiting interval in seconds. Default value is 0, which turns off rate limiting. Set it to a number of seconds (5 recommended) to activate rate-limiting. The default of 0 has been choosen as people experienced problems with this feature activated by default. Now it needs an explicit opt-in by setting this parameter.
  • RateLimit.Burst [number] - specifies the rate-limiting burst in number of messages. Default is 200.
  • RateLimit.Severity [numerical severity] - specifies the severity of messages that shall be rate-limited.
  • UsePIDFromSystem [on/off] - specifies if the pid being logged shall be obtained from the log socket itself. If so, the TAG part of the message is rewritten. It is recommended to turn this option on, but the default is "off" to keep compatible with earlier versions of rsyslog.
  • UseSysTimeStamp [on/off] instructs imuxsock to obtain message time from the system (via control messages) insted of using time recorded inside the message. This may be most useful in combination with systemd. Note: this option was introduced with version 5.9.1. Due to the usefulness of it, we decided to enable it by default. As such, 5.9.1 and above behave slightly different than previous versions. However, we do not see how this could negatively affect existing environments.
  • CreatePath [on/off] - create directories in the socket path if they do not already exist. They are created with 0755 permissions with the owner being the process under which rsyslogd runs. The default is not to create directories. Keep in mind, though, that rsyslogd always creates the socket itself if it does not exist (just not the directories by default).
    Note that this statement affects the next Socket directive that follows in sequence in the configuration file. It never works on the system log socket (where it is deemed unnecessary). Also note that it is automatically being reset to "off" after the Socket directive, so if you would have it active for two additional listen sockets, you need to specify it in front of each one. This option is primarily considered useful for defining additional sockets that reside on non-permanent file systems. As rsyslogd probably starts up before the daemons that create these sockets, it is a vehicle to enable rsyslogd to listen to those sockets even though their directories do not yet exist.
  • Socket <name-of-socket> adds additional unix socket, default none -- former -a option
  • HostName <hostname> permits to override the hostname that shall be used inside messages taken from the next Socket socket. Note that the hostname must be specified before the $AddUnixListenSocket configuration directive, and it will only affect the next one and then automatically be reset. This functionality is provided so that the local hostname can be overridden in cases where that is desired.
  • Annotate <on/off> turn on annotation/trusted properties for the non-system log socket in question.
  • ParseTrusted <on/off> equivalent to the SysSock.ParseTrusted module parameter, but applies to the input that is being defined.
  • Unlink <on/off> (available since 7.3.9)
    if turned on (default), the socket is unlinked and re-created when opened and also unlinked when finally closed. Set it to off if you handle socket creation yourself. Note that handling socket creation oneself has the advantage that a limited amount of messages may be queued by the OS if rsyslog is not running.
Caveats/Known Bugs:
  • There is a compile-time limit of 50 concurrent sockets. If you need more, you need to change the array size in imuxsock.c.
  • This documentation is sparse and incomplete.

Sample:

The following sample is the minimum setup required to accept syslog messages from applications running on the local system.

The following sample is similiar to the first one, but enables trusted properties, which are put into JSON/lumberjack variables.

The following sample is a configuration where rsyslogd pulls logs from two jails, and assigns different hostnames to each of the jails:

The following sample is a configuration where rsyslogd reads the openssh log messages via a separate socket, but this socket is created on a temporary file system. As rsyslogd starts up before the sshd, it needs to create the socket directories, because it otherwise can not open the socket and thus not listen to openssh messages. Note that it is vital not to place any other socket between the CreatePath and the Socket.

Basic rsyslog.conf Structure

This is a part of the rsyslog.conf documentation.

Back to rsyslog.conf manual

Rsyslog supports three different types of configuration statements concurrently:

  • sysklogd - this is the plain old format, thaught everywhere and still pretty useful for simple use cases. Note that some very few constructs are no longer supported because they are incompatible with newer features. These are mentioned in the compatibility docs.
  • legacy rsyslog - these are statements that begin with a dollar sign. They set some configuration parameters and modify e.g. the way actions operate. This is the only format supported in pre-v6 versions of rsyslog. It is still fully supported in v6 and above. Note that some plugins and features may still only be available through legacy format (because plugins need to be explicitely upgraded to use the new style format, and this hasn't happened to all plugins).
  • RainerScript - the new style format. This is the best and most precise format to be used for more complex cases. The rest of this page assumes RainerScript based rsyslog.conf.

The rsyslog.conf files consists of statements. For old style (sysklogd & legacy rsyslog), lines do matter. For new style (RainerScript) line spacing is irrelevant. Most importantly, this means with new style actions and all other objects can split across lines as users want to.

Comments

There are two types of comments:

  • #-Comments - start with a hash sign (#) and run to the end of the line
  • C-style Comments - start with /* and end with */, just like in the C programming language. They can be used to comment out multiple lines at one. Comment nesting is not supported, but #-Comments can be contained inside a C-style comment.

Processing Order

Directives are processed from the top of rsyslog.conf to the bottom. Sequence matters. For example, if you stop processing of a message, obviously all statements after the stop statement are never evaluated.

Flow Control Statements

  • if expr then ... else ... - conditional execution
  • stop - stops processing the current message
  • call - calls a ruleset (just like a subroutine call)
  • continue - a NOP, useful e.g. inside the then part of an if

Data Manipulation Statements

  • set - sets a user variable
  • unset - deletes a previously set user variable

Inputs

Every input requires an input module to be loaded and a listener defined for it. Full details can be found inside the rsyslog modules documentation. Once loaded, inputs are defined via the input() object.

Outputs

Outputs are also called "actions". A small set of actions is pre-loaded (like the output file writer, which is used in almost every rsyslog.conf), others must be loaded just like inputs.

An action is invoked via the action(type="type" ...) object. Type is mandatory and must contain the name of the plugin to be called (e.g. "omfile" or "ommongodb"). Other paramters may be present. Their type and use depends on the output plugin in question.

Rulesets and Rules

Rulesets and rules form the basis of rsyslog processing. In short, a rule is a way how rsyslog shall process a specific message. Usually, there is a type of filter (if-statement) in front of the rule. Complex nesting of rules is possible, much like in a programming language.

Rulesets are containers for rules. A single ruleset can contain many rules. In the programming language analogy, one may think of a ruleset like being a program. A ruleset can be "bound" (assigned) to a specific input. In the analogy, this means that when a message comes in via that input, the "program" (ruleset) bound to it will be executed (but not any other!).

There is detail documentation available for rsyslog rulesets.

For quick reference, rulesets are defined as follows: 

ruleset(name="rulesetname") {
	action(type="omfile" file="/path/to/file")
	action(type="..." ...)
	/* and so on... */
}

Generic design of a syslogd

Written 2007-04-10 by Rainer Gerhards

The text below describes a generic approach on how a syslogd can be implemented. I created this description for some other project, where it was not used. Instead of throwing it away, I thought it would be a good addition to the rsyslog documentation. While rsyslog differs in details from the description below, it is sufficiently close to it. Further development of rsyslog will probably match it even closer to the description.

If you intend to read the rsyslog source code, I recommend reading this document here first. You will not find the same names and not all of the concepts inside rsyslog. However, I think your understanding will benefit from knowing the generic architecture.

                Generic Syslog Application Architecture
  • A "syslog application" is an application whose purpose is the processing of syslog messages. It may be part of a larger application with a broader purpose. An example: a database application might come with its own syslog send subsystem and not go through a central syslog application. In the sense of this document, that application is called a "syslog application" even though a casual observer might correctly call it a database application and may not even know that it supports sending of syslog messages.
  • Payload is the information that is to be conveyed. Payload by itself may have any format and is totally independent from to format specified in this document. The "Message CoDec" of the syslog application will bring it into the required format.
  • Payload Originators ("PLOrig") are the original creators of payload. Typically, these are application programs.
  • A "Remote PLOrig" is a payload originator residing in a different application than the syslog application itself. That application may reside on a different machine and may talk to the syslog application via RPC.
  • A "PLOrig" is a payload originator residing within the syslog application itself. Typically, this PLOrig emits syslog application startup, shutdown, error and status log messages.
  • A "GWI" is a inbound gateway. For example, a SNMP-to-syslog gateway may receive SNMP messages and translate them into syslog.
  • The ellipsis after "GWI" indicates that there are potentially a variety of different other ways to originally generate payload.
  • A "PLGenerator" is a payload generator. It takes the information from the payload-generating source and integrates it into the syslog subsystem of the application. This is a highly theoretical concept. In practice, there may not actually be any such component. Instead, the payload generators (or other parts like the GWI) may talk directly to the syslog subsystem. Conceptually, the "PLGenerator" is the first component where the information is actually syslog content.
  • A "PLG Ext" is a payload generator extension. It is used to modify the syslog information. An example of a "PLG Ext" might be the addition of cryptographic signatures to the syslog information.
  • A "Message Router" is a component that accepts in- and outbound syslog information and routes it to the proper next destination inside the syslog application. The routing information itself is expected to be learnt by operator configuration.
  • A "Message CoDec" is the message encoder/decoder. The encoder takes syslog information and encodes them into the required format
    for a syslog message. The decoder takes a syslog message and decodes it into syslog information. Codecs for multiple syslog formats may be present inside a single syslog application.
  • A transport (UDP, TLS, yet-to-be-defined ones) sends and receives syslog messages. Multiple transports may be used by a single
    syslog application at the same time. A single transport instance may be used for both sending and receiving. Alternatively, a single instance might be used for sending and receiving exclusively. Multiple instances may be used for different listener ports and receivers.
  • A "RelayEng" is the relaying engine. It provides functionality necessary for receiving syslog information and sending it to another syslog application.
  • A "RelEng Ext" is an extension that processes syslog information as it enters or exits a RelayEng. An example of such a component might be a relay cryptographically signing received syslog messages. Such a function might be useful to guarantee authenticity starting from a given point inside a relay chain.
  • A "CollectorEng" is a collector engine. At this component, syslog information leaves the syslog system and is translated into some other form. After the CollectorEng, the information is no longer defined to be of native syslog type.
  • A "CollcEng Ext" is a collector engine extension. It modifies syslog information before it is passed on to the CollectorEng. An example for this might be the verification of cryptographically signed syslog message information. Please note that another implementation approach would be to do the verification outside of the syslog application or in a stage after "CollectorEng".
  • A "GWO" is an outbound gateway. An example of this might be the forwarding of syslog information via SNMP or SMTP. Please note that when a GWO directly connects to a GWI on a different syslog application, no native exchange of syslog information takes place. Instead, the native protocol of these gateways (e.g. SNMP) is used. The syslog information is embedded inside that protocol. Depending on protocol and gateway implementation, some of the native syslog information might be lost.
  • A "Store" is any way to persistently store the extracted syslog information, e.g. to the file system or to a data base.
  • "Disc" means the discarding of messages. Operators often find it useful to discard noise messages and so most syslog applications
    contain a way to do that.
  • The ellipsis after "Disc" indicates that there are potentially a variety of different other ways to consume syslog information.
  • There may be multiple instances of each of the described components in a single syslog application.
  • A syslog application is made up of all or some of the above mentioned components.

Unix sockets Output Module (omhdfs)

Module Name:    omhdfs

Available since:    5.7.1

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module supports writing message into files on Hadoop's HDFS file system.

Configuration Directives:

  • $OMHDFSFileName [name]
    The name of the file to which the output data shall be written.
  • $OMHDFSHost [name]
    Name or IP address of the HDFS host to connect to.
  • $OMHDFSPort [name]
    Port on which to connect to the HDFS host.
  • $OMHDFSDefaultTemplate [name]
    Default template to be used when none is specified. This saves the work of specifying the same template ever and ever again. Of course, the default template can be overwritten via the usual method.
Caveats/Known Bugs:

Building omhdfs is a challenge because we could not yet find out how to integrate Java properly into the autotools build process. The issue is that HDFS is written in Java and libhdfs uses JNI to talk to it. That requires that various system-specific environment options and pathes be set correctly. At this point, we leave this to the user. If someone know how to do it better, please drop us a line!

  • In order to build, you need to set these environment variables BEFORE running ./configure:
    • JAVA_INCLUDES - must have all include pathes that are needed to build JNI C programms, including the -I options necessary for gcc. An example is
      # export JAVA_INCLUDES="-I/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/include -I/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/include/linux"
    • JAVA_LIBS - must have all library pathes that are needed to build JNI C programms, including the -l/-L options necessary for gcc. An example is
      # export export JAVA_LIBS="-L/usr/java/jdk1.6.0_21/jre/lib/amd64 -L/usr/java/jdk1.6.0_21/jre/lib/amd64/server -ljava -ljvm -lverify"
  • As of HDFS architecture, you must make sure that all relevant environment variables (the usual Java stuff and HADOOP's home directory) are properly set.
  • As it looks, libhdfs makes Java throw exceptions to stdout. There is no known work-around for this (and it usually should not case any troubles.

$RulesetParser

Type: ruleset-specific configuration directive

Parameter Values: string

Available since: 5.3.4+

Default: rsyslog.rfc5424 followed by rsyslog.rfc3164

Description:

This directive permits to specify which message parsers should be used for the ruleset in question. It no ruleset is explicitely specified, the default ruleset is used. Message parsers are contained in (loadable) parser modules with the most common cases (RFC3164 and RFC5424) being build-in into rsyslogd.

When this directive is specified the first time for a ruleset, it will not only add the parser to the ruleset's parser chain, it will also wipe out the default parser chain. So if you need to have them in addition to the custom parser, you need to specify those as well.

Order of directives is important. Parsers are tried one after another, in the order they are specified inside the config. As soon as a parser is able to parse the message, it will do so and no other parsers will be executed. If no matching parser can be found, the message will be discarded and a warning message be issued (but only for the first 1,000 instances of this problem, to prevent message generation loops).

Note that the rfc3164 parser will always be able to parse a message - it may just not be the format that you like. This has two important implications: 1) always place that parser at the END of the parser list, or the other parsers after it will never be tried and 2) if you would like to make sure no message is lost, placing the rfc3164 parser at the end of the parser list ensures that.

Multiple parser modules are very useful if you have various devices that emit messages that are malformed in various ways. The route to take then is

  • make sure you find a custom parser for that device; if there is no one, you may consider writing one yourself (it is not that hard) or getting one written as part of Adiscon's professional services for rsyslog.
  • load your custom parsers via $ModLoad
  • create a ruleset for each malformed format; assign the custom parser to it
  • create a specific listening port for all devices that emit the same malformed format
  • bind the listener to the ruleset with the required parser

Note that it may be cumbersome to add all rules to all rulesets. To avoid this, you can either use $Include or omruleset (what probably provides the best solution).

More information about rulesets in general can be found in multi-ruleset support in rsyslog.

Caveats:

currently none known

Example:

This example assumes there are two devices emiting malformed messages via UDP. We have two custom parsers for them, named "device1.parser" and "device2.parser". In addition to that, we have a number of other devices sending wellformed messages, also via UDP.

The solution is to listen for data from the two devices on two special ports (10514 and 10515 in this example), create a ruleset for each and assign the custom parsers to them. The rest of the messages are received via port 514 using the regular parsers. Processing shall be equal for all messages. So we simply forward the malformed messages to the regular queue once they are parsed (keep in mind that a message is never again parsed once any parser properly processed it).

For an example of how multiple parser can be chained (and an actual use case), please see the example section on the pmlastmsg parser module.

Note the positions of the directives. With the current config language, sequence of statements is very important. This is ugly, but unfortunately the way it currently works.

SSL Encrypting Syslog with Stunnel

Written by Rainer Gerhards (2005-07-22)

Abstract

In this paper, I describe how to encrypt syslog messages on the network. Encryption is vital to keep the confidiental content of syslog messages secure. I describe the overall approach and provide an HOWTO do it with the help of rsyslogd and stunnel.

Please note that starting with rsyslog 3.19.0, rsyslog provides native TLS/SSL encryption without the need of stunnel. I strongly recomend to use that feature instead of stunnel. The stunnel documentation here is mostly provided for backwards compatibility. New deployments are advised to use native TLS mode.

Background

Syslog is a clear-text protocol. That means anyone with a sniffer can have a peek at your data. In some environments, this is no problem at all. In others, it is a huge setback, probably even preventing deployment of syslog solutions. Thankfully, there is an easy way to encrypt syslog communication. I will describe one approach in this paper.

The most straightforward solution would be that the syslogd itself encrypts messages. Unfortuantely, encryption is only standardized in RFC 3195. But there is currently no syslogd that implements RFC 3195's encryption features, so this route leads to nothing. Another approach would be to use vendor- or project-specific syslog extensions. There are a few around, but the problem here is that they have compatibility issues. However, there is one surprisingly easy and interoperable solution: though not standardized, many vendors and projects implement plain tcp syslog. In a nutshell, plain tcp syslog is a mode where standard syslog messages are transmitted via tcp and records are separated by newline characters. This mode is supported by all major syslogd's (both on Linux/Unix and Windows) as well as log sources (for example, EventReporter for Windows Event Log forwarding). Plain tcp syslog offers reliability, but it does not offer encryption in itself. However, since it operates on a tcp stream, it is now easy to add encryption. There are various ways to do that. In this paper, I will describe how it is done with stunnel (an other alternative would be IPSec, for example).

Stunnel is open source and it is available both for Unix/Linux and Windows. It provides a way to use ssl communication for any non-ssl aware client and server - in this case, our syslogd.

Stunnel works much like a wrapper. Both on the client and on the server machine, tunnel portals are created. The non-ssl aware client and server software is configured to not directly talk to the remote partner, but to the local (s)tunnel portal instead. Stunnel, in turn, takes the data received from the client, encrypts it via ssl, sends it to the remote tunnel portal and that remote portal sends it to the recipient process on the remote machine. The transfer to the portals is done via unencrypted communication. As such, it is vital that the portal and the respective program that is talking to it are on the same machine, otherwise data would travel partly unencrypted. Tunneling, as done by stunnel, requires connection oriented communication. This is why you need to use tcp-based syslog. As a side-note, you can also encrypt a plain-text RFC 3195 session via stunnel, though this definitely is not what the protocol designers had on their mind ;)

In the rest of this document, I assume that you use rsyslog on both the client and the server. For the samples, I use Debian. Interestingly, there are some annoying differences between stunnel implementations. For example, on Debian a comment line starts with a semicolon (';'). On Red Hat, it starts with a hash sign ('#'). So you need to watch out for subtle issues when setting up your system.

Overall System Setup

In ths paper, I assume two machines, one named "client" and the other named "server". It is obvious that, in practice, you will probably have multiple clients but only one server. Syslog traffic shall be transmitted via stunnel over the network. Port 60514 is to be used for that purpose. The machines are set up as follows:

Client

  • rsyslog forwards  message to stunnel local portal at port 61514
  • local stunnel forwards data via the network to port 60514 to its remote peer

Server

  • stunnel listens on port 60514 to connections from its client peers
  • all connections are forwarded to the locally-running rsyslog listening at port 61514

Setting up the system

For Debian, you need the "stunnel4" package. The "stunnel" package is the older 3.x release, which will not support the configuration I describe below. Other distributions might have other names. For example, on Red Hat it is just "stunnel". Make sure that you install the appropriate package on both the client and the server. It is also a good idea to check if there are updates for either stunnel or openssl (which stunnel uses) - there are often security fixes available and often the latest fixes are not included in the default package.

In my sample setup, I use only the bare minimum of options. For example, I do not make the server check client cerficiates. Also, I do not talk much about certificates at all. If you intend to really secure your system, you should probably learn about certificates and how to manage and deploy them. This is beyond the scope of this paper. For additional information, http://www.stunnel.org/faq/certs.html is a good starting point.

You also need to install rsyslogd on both machines. Do this before starting with the configuration. You should also familarize yourself with its configuration file syntax, so that you know which actions you can trigger with it. Rsyslogd can work as a drop-in replacement for stock sysklogd. So if you know the standard syslog.conf syntax, you do not need to learn any more to follow this paper.

Server Setup

At the server, you need to have a digital certificate. That certificate enables SSL operation, as it provides the necessary crypto keys being used to secure the connection. Many versions of stunnel come with a default certificate, often found in /etc/stunnel/stunnel.pem. If you have it, it is good for testing only. If you use it in production, it is very easy to break into your secure channel as everybody is able to get hold of your private key. I didn't find an stunnel.pem on my Debian machine. I guess the Debian folks removed it because of its insecurity.

You can create your own certificate with a simple openssl tool - you need to do it if you have none and I highly recommend to create one in any case. To create it, cd to /etc/stunnel and type:

openssl req -new -x509 -days 3650 -nodes -out stunnel.pem -keyout stunnel.pem

That command will ask you a number of questions. Provide some answer for them. If you are unsure, read http://www.stunnel.org/faq/certs.html. After the command has finished, you should have a usable stunnel.pem in your working directory.

Next is to create a configuration file for stunnel. It will direct stunnel what to do. You can used the following basic file:

; Certificate/key is needed in server mode
cert = /etc/stunnel/stunnel.pem

; Some debugging stuff useful for troubleshooting
debug = 7
foreground=yes

[ssyslog]
accept  = 60514
connect = 61514

Save this file to e.g. /etc/stunnel/syslog-server.conf. Please note that the settings in italics are for debugging only. They run stunnel with a lot of debug information in the foreground. This is very valuable while you setup the system - and very useless once everything works well. So be sure to remove these lines when going to production.

Finally, you need to start the stunnel daemon. Under Debian, this is done via "stunnel /etc/stunnel/syslog.server.conf". If you have enabled the debug settings, you will immediately see a lot of nice messages.

Now you have stunnel running, but it obviously unable to talk to rsyslog - because it is not yet running. If not already done, configure it so that it does everything you want. If in doubt, you can simply copy /etc/syslog.conf to /etc/rsyslog.conf and you probably have what you want. The really important thing in rsyslogd configuration is that you must make it listen to tcp port 61514 (remember: this is where stunnel send the messages to). Thankfully, this is easy to achive: just add "-t 61514" to the rsyslogd startup options in your system startup script. After done so, start (or restart) rsyslogd.

The server should now be fully operational.

Client Setup

The client setup is simpler. Most importantly, you do not need a certificate (of course, you can use one if you would like to authenticate the client, but this is beyond the scope of this paper). So the basic thing you need to do is create the stunnel configuration file.

; Some debugging stuff useful for troubleshooting
debug = 7
foreground=yes

client=yes

[ssyslog]
accept  = 127.0.0.1:61514
connect = 192.0.2.1:60514

Again, the text in italics is for debugging purposes only. I suggest you leave it in during your initial testing and then remove it. The most important difference to the server configuration outlined above is the "client=yes" directive. It is what makes this stunnel behave like a client. The accept directive binds stunnel only to the local host, so that it is protected from receiving messages from the network (somebody might fake to be the local sender). The address "192.0.2.1" is the address of the server machine. You must change it to match your configuration. Save this file to /etc/stunnel/syslog-client.conf.

Then, start stunnel via "stunnel4 /etc/stunnel/syslog-client.conf".  Now you should see some startup messages. If no errors appear, you have a running client stunnel instance.

Finally, you need to tell rsyslogd to send data to the remote host. In stock syslogd, you do this via the "@host" forwarding directive. The same works with rsyslog, but it suppports extensions to use tcp. Add the following line to your /etc/rsyslog.conf:

*.*      @@127.0.0.1:61514

Please note the double at-sign (@@). This is no typo. It tells rsyslog to use tcp instead of udp delivery. In this sample, all messages are forwarded to the remote host. Obviously, you may want to limit this via the usual rsyslog.conf settings (if in doubt, use man rsyslog.con).

You do not need to add any special startup settings to rsyslog on the client. Start or restart rsyslog so that the new configuration setting takes place.

Done

After following these steps, you should have a working secure syslog forwarding system. To verify, you can type "logger test" or a similar smart command on the client. It should show up in the respective server log file. If you dig out you sniffer, you should see that the traffic on the wire is actually protected. In the configuration use above, the two stunnel endpoints should be quite chatty, so that you can follow the action going on on your system.

If you have only basic security needs, you can probably just remove the debug settings and take the rest of the configuration to production. If you are security-sensitve, you should have a look at the various stunnel settings that help you further secure the system.

Preventing Systems from talking directly to the rsyslog Server

It is possible that remote systems (or attackers) talk to the rsyslog server by directly connecting to its port 61514. Currently (July of 2005), rsyslog does not offer the ability to bind to the local host, only. This feature is planned, but as long as it is missing, rsyslog must be protected via a firewall. This can easily be done via e.g iptables. Just be sure not to forget it.

Conclusion

With minumal effort, you can set up a secure logging infrastructure employing ssl encrypted syslog message transmission. As a side note, you also have the benefit of reliable tcp delivery which is far less prone to message loss than udp.

Feedback requested

I would appreciate feedback on this tutorial. If you have additional ideas, comments or find bugs (I *do* bugs - no way... ;)), please let me know.

This module provides native support for logging to MySQL databases. It offers superior performance over the more generic omlibdbi module.

Action Parameters:

  • server
    Name or address of the MySQL server
  • serverport
    Permits to select a non-standard port for the MySQL server. The default is 0, which means the system default port is used. There is no need to specify this parameter unless you know the server is running on a non-standard listen port.
  • db
    Database to use
  • uid
    logon userid used to connect to server. Must have proper permissions.
  • pwd
    the user's password
  • template
    Template to use when submitting messages.
  • mysqlconfig.file
    Permits the selection of an optional MySQL Client Library configuration file (my.cnf) for extended configuration functionality. The use of this configuration directive is necessary only if you have a non-standard environment or if fine-grained control over the database connection is desired.
  • mysqlconfig.section
    Permits the selection of the section within the configuration file specified by the myselconfig.file parameter.
    This will likely only be used where the database administrator provides a single configuration file with multiple profiles.
    This configuration parameter is ignored unless mysqlconfig.file is also used.
    If omitted, the MySQL Client Library default of "client" will be used.

Legacy (pre-v6) Configuration Directives:

ommysql mostly uses the "very old style" (v0) configuration, with almost everything on the action line itself.

  • $ActionOmmysqlServerPort <port> - like the "serverport" action parameter.
  • $OmMySQLConfigFile <file name> - like the "mysqlconfig.file" action parameter.
  • $OmMySQLConfigSection <string> - like the "mysqlconfig.file" action parameter.
  • Action line:
    :ommysql:database-server,database-name,database-userid,database-password
    All parameters should be filled in for a successful connect.

Note rsyslog contains a canned default template to write to the MySQL database. It works on the MonitorWare schema. This template is:

As you can see, the template is an actual SQL statement. Note the ",SQL" option: it tells the template processor that the template is used for SQL processing, thus quote characters are quoted to prevent security issues. You can not assign a template without ",SQL" to a MySQL output action.

If you would like to change fields contents or add or delete your own fields, you can simply do so by modifying the schema (if required) and creating your own custom template.

Sample:

The following sample writes all syslog messages to the database "syslog_db" on mysqlsever.example.com. The server is being accessed under the account of "user" with password "pwd".

Legacy Sample:

The same as above, but in legacy config format (pre rsyslog-v6):

Encrypting Syslog Traffic with TLS (SSL)

Written by Rainer Gerhards (2008-06-17)

Setting up the CA

The first step is to set up a certificate authority (CA). It must be maintained by a trustworthy person (or group) and approves the indentities of all machines. It does so by issuing their certificates. In a small setup, the administrator can provide the CA function. What is important is the the CA's private key is well-protocted and machine certificates are only issued if it is know they are valid (in a single-admin case that means the admin should not issue certificates to anyone else except himself).

The CA creates a so-called self-signed certificate. That is, it approves its own authenticy. This sounds useless, but the key point to understand is that every machine will be provided a copy of the CA's certificate. Accepting this certificate is a matter of trust. So by configuring the CA certificate, the administrator tells rsyslog which certificates to trust. This is the root of all trust under this model. That is why the CA's private key is so important - everyone getting hold of it is trusted by our rsyslog instances.

To create a self-signed certificate, use the following commands with GnuTLS (which is currently the only supported TLS library, what may change in the future). Please note that GnuTLS' tools are not installed by default on many platforms. Also, the tools do not necessarily come with the GnuTLS core package. If you do not have certtool on your system, check if there is package for the GnuTLS tools available (under Fedora, for example, this is named gnutls-utils-<version> and it is NOT installed by default).

  1. generate the private key: 
    certtool --generate-privkey --outfile ca-key.pem

    This takes a short while. Be sure to do some work on your workstation, it waits for radom input. Switching between windows is sufficient ;)
  2. now create the (self-signed) CA certificate itself:
    certtool --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem
    This generates the CA certificate. This command queries you for a number of things. Use appropriate responses. When it comes to certificate validity, keep in mind that you need to recreate all certificates when this one expires. So it may be a good idea to use a long period, eg. 3650 days (roughly 10 years). You need to specify that the certificates belongs to an authority. The certificate is used to sign other certificates.

Plain TCP Syslog Input Module

Module Name:    imptcp

Available since: 4.7.3+, 5.5.8+

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

Provides the ability to receive syslog messages via plain TCP syslog. This is a specialised input plugin tailored for high performance on Linux. It will probably not run on any other platform. Also, it does not provide TLS services. Encryption can be provided by using stunnel.

This module has no limit on the number of listeners and sessions that can be used.

Configuration Directives:

This plugin has config directives similar named as imtcp, but they all have PTCP in their name instead of just TCP. Note that only a subset of the parameters are supported.

    Module Parameters:

    These paramters can be used with the "module()" statement. They apply globaly to all inputs defined by the module.

    • Threads <number>
      Number of helper worker threads to process incoming messages. These threads are utilized to pull data off the network. On a busy system, additional helper threads (but not more than there are CPUs/Cores) can help improving performance. The default value is two, which means there is a default thread count of three (the main input thread plus two helpers). No more than 16 threads can be set (if tried to, rsyslog always resorts to 16).

    Input Parameters:

    These parameters can be used with the "input()" statement. They apply to the input they are specified with.

    • AddtlFrameDelimiter <Delimiter>
      This directive permits to specify an additional frame delimiter for plain tcp syslog. The industry-standard specifies using the LF character as frame delimiter. Some vendors, notable Juniper in their NetScreen products, use an invalid frame delimiter, in Juniper's case the NUL character. This directive permits to specify the ASCII value of the delimiter in question. Please note that this does not guarantee that all wrong implementations can be cured with this directive. It is not even a sure fix with all versions of NetScreen, as I suggest the NUL character is the effect of a (common) coding error and thus will probably go away at some time in the future. But for the time being, the value 0 can probably be used to make rsyslog handle NetScreen's invalid syslog/tcp framing. For additional information, see this forum thread.
      If this doesn't work for you, please do not blame the rsyslog team. Instead file a bug report with Juniper!
      Note that a similar, but worse, issue exists with Cisco's IOS implementation. They do not use any framing at all. This is confirmed from Cisco's side, but there seems to be very limited interest in fixing this issue. This directive can not fix the Cisco bug. That would require much more code changes, which I was unable to do so far. Full details can be found at the Cisco tcp syslog anomaly page.
    • SupportOctetCountedFraming <on|off>
      If set to "on", the legacy octed-counted framing (similar to RFC5425 framing) is activated. This is the default and should be left unchanged until you know very well what you do. It may be useful to turn it off, if you know this framing is not used and some senders emit multi-line messages into the message stream.
    • ServerNotifyOnConnectionClose [on/off]
      instructs imptcp to emit a message if the remote peer closes a connection.
    • KeepAlive <on/off>
      enable of disable keep-alive packets at the tcp socket layer. The default is to disable them.
    • KeepAlive.Probes <number>
      The number of unacknowledged probes to send before considering the connection dead and notifying the application layer. The default, 0, means that the operating system defaults are used. This has only effect if keep-alive is enabled. The functionality may not be available on all platforms.
    • KeepAlive.Interval <number>
      The interval between subsequential keepalive probes, regardless of what the connection has exchanged in the meantime. The default, 0, means that the operating system defaults are used. This has only effect if keep-alive is enabled. The functionality may not be available on all platforms.
    • KeepAlive.Time <number>
      The interval between the last data packet sent (simple ACKs are not considered data) and the first keepalive probe; after the connection is marked to need keepalive, this counter is not used any further. The default, 0, means that the operating system defaults are used. This has only effect if keep-alive is enabled. The functionality may not be available on all platforms.
    • Port <number>
      Select a port to listen on
    • Name <name>
      Sets a name for the inputname property. If no name is set "imptcp" is used by default. Setting a name is not strictly necessary, but can be useful to apply filtering based on which input the message was received from.
    • Ruleset <name>
      Binds specified ruleset to next server defined.
    • Address <name>
      On multi-homed machines, specifies to which local address the listerner should be bound.
    • RateLimit.Interval [number] - (available since 7.3.1) specifies the rate-limiting interval in seconds. Default value is 0, which turns off rate limiting. Set it to a number of seconds (5 recommended) to activate rate-limiting.
    • RateLimit.Burst [number] - (available since 7.3.1) specifies the rate-limiting burst in number of messages. Default is 10,000.

    EQUALLY-NAMED TEMPLATES

    If multiple templates with the SAME name are created, all but the first definition is IGNORED. So you can NOT (yet) replace a template definition. I also strongly doubt I will ever support this, because it does not make an awful lot of sense (after all, why not use two template names...).

    WALLMSG FORMAT (* selector)

    This format is actually not 100% compatible with stock syslogd - the date is missing. Will be fixed soon and can also be fixed just via the proper template. Anyone up for this? ;)

    MULTIPLE INSTANCES

    If multiple instances are running on a single machine, the one with the -r switch must start first. Also, UDP-based syslog forwarding between the instances does not work. Use TCP instead.

    SNMP Output Module

    Module Name:    omsnmp

    Author: Andre Lorbach <alorbach@adiscon.com>

    Description:

    Provides the ability to send syslog messages as an SNMPv1 & v2c traps. By default, SNMPv2c is preferred. The syslog message is wrapped into a OCTED STRING variable. This module uses the NET-SNMP library. In order to compile this module, you will need to have the NET-SNMP developer (headers) package installed.

     

    Action Line:

    %omsnmp% without any further parameters.

     

    Configuration Directives:

    • transport (This parameter is optional, the default value is "udp")

      Defines the transport type you wish to use. Technically we can support all transport types which are supported by NET-SNMP.
      To name a few possible values:

      udp, tcp, udp6, tcp6, icmp, icmp6 ...

      Example: transport udp
    • server

      This can be a hostname or ip address, and is our snmp target host. This parameter is required, if the snmptarget is not defined, nothing will be send.

      Example: server server.domain.xxx
    • port (This parameter is optional, the default value is "162")

      The port which will be used, common values are port 162 or 161.

      Example: port 162
    • version (This parameter is optional, the default value is "1")

      There can only be two choices for this parameter for now.
      0 means SNMPv1 will be used.
      1 means SNMPv2c will be used.
      Any other value will default to 1.

      Example: version 1
    • community (This parameter is optional, the default value is "public")

      This sets the used SNMP Community.

      Example: community public

    • trapoid (This parameter is optional, the default value is "1.3.6.1.4.1.19406.1.2.1" which means "ADISCON-MONITORWARE-MIB::syslogtrap")
      This configuration parameter is used for SNMPv2 only.

      This is the OID which defines the trap-type, or notifcation-type rsyslog uses to send the trap.
      In order to decode this OID, you will need to have the ADISCON-MONITORWARE-MIB and ADISCON-MIB mibs installed on the receiver side. Downloads of these mib files can be found here:
      http://www.adiscon.org/download/ADISCON-MIB.txt
      http://www.adiscon.org/download/ADISCON-MONITORWARE-MIB.txt

      Thanks to the net-snmp mailinglist for the help and the recommendations ;).

      Example: trapoid 1.3.6.1.4.1.19406.1.2.1
      If you have this MIBS installed, you can also configured with the OID Name: trapoid ADISCON-MONITORWARE-MIB::syslogtrap
    • messageoid (This parameter is optional, the default value is "1.3.6.1.4.1.19406.1.1.2.1" which means "ADISCON-MONITORWARE-MIB::syslogMsg")

      This OID will be used as a variable, type "OCTET STRING". This variable will contain up to 255 characters of the original syslog message including syslog header. It is recommend to use the default OID.
      In order to decode this OID, you will need to have the ADISCON-MONITORWARE-MIB and ADISCON-MIB mibs installed on the receiver side. To download these custom mibs, see the description of $actionsnmptrapoid.

      Example: messageoid 1.3.6.1.4.1.19406.1.1.2.1
      If you have this MIBS installed, you can also configured with the OID Name: messageoid ADISCON-MONITORWARE-MIB::syslogMsg

    • enterpriseoid (This parameter is optional, the default value is "1.3.6.1.4.1.3.1.1" which means "enterprises.cmu.1.1")

      Customize this value if needed. I recommend to use the default value unless you require to use a different OID.
      This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: enterpriseoid 1.3.6.1.4.1.3.1.1

    • specifictype (This parameter is optional, the default value is "0")

      This is the specific trap number. This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: specifictype 0

    • traptype (This parameter is optional, the default value is "6" which means SNMP_TRAP_ENTERPRISESPECIFIC)

      There are only 7 Possible trap types defined which can be used here. These trap types are:
      0 = SNMP_TRAP_COLDSTART
      1 = SNMP_TRAP_WARMSTART
      2 = SNMP_TRAP_LINKDOWN
      3 = SNMP_TRAP_LINKUP
      4 = SNMP_TRAP_AUTHFAIL
      5 = SNMP_TRAP_EGPNEIGHBORLOSS
      6 = SNMP_TRAP_ENTERPRISESPECIFIC

      Any other value will default to 6 automatically. This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: traptype 6
    • template [templateName]

      sets a new default template for file actions.

     

    Caveats/Known Bugs:

    • In order to decode the custom OIDs, you will need to have the adiscon mibs installed.

    Sample:

    The following commands send every message as a snmp trap.

    • $actionsnmpenterpriseoid (This parameter is optional, the default value is "1.3.6.1.4.1.3.1.1" which means "enterprises.cmu.1.1")

      Customize this value if needed. I recommend to use the default value unless you require to use a different OID.
      This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: $actionsnmpenterpriseoid 1.3.6.1.4.1.3.1.1

    • $actionsnmpspecifictype (This parameter is optional, the default value is "0")

      This is the specific trap number. This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: $actionsnmpspecifictype 0

    • $actionsnmptraptype (This parameter is optional, the default value is "6" which means SNMP_TRAP_ENTERPRISESPECIFIC)

      There are only 7 Possible trap types defined which can be used here. These trap types are:
      0 = SNMP_TRAP_COLDSTART
      1 = SNMP_TRAP_WARMSTART
      2 = SNMP_TRAP_LINKDOWN
      3 = SNMP_TRAP_LINKUP
      4 = SNMP_TRAP_AUTHFAIL
      5 = SNMP_TRAP_EGPNEIGHBORLOSS
      6 = SNMP_TRAP_ENTERPRISESPECIFIC

      Any other value will default to 6 automatically. This configuration parameter is used for SNMPv1 only. It has no effect if SNMPv2 is used.

      Example: $actionsnmptraptype 6

     

    Caveats/Known Bugs:

    • In order to decode the custom OIDs, you will need to have the adiscon mibs installed.

    $MainMsgQueueSize

    Type: global configuration directive

    Default: 10000

    Description:

    This allows to specify the maximum size of the message queue. This directive is only available when rsyslogd has been compiled with multithreading support. In this mode, receiver and output modules are de-coupled via an in-memory queue. This queue buffers messages when the output modules are not capable to process them as fast as they are received. Once the queue size is exhausted, messages will be dropped. The slower the output (e.g. MySQL), the larger the queue should be. Buffer space for the actual queue entries is allocated on an as-needed basis. Please keep in mind that a very large queue may exhaust available system memory and swap space. Keep this in mind when configuring the max size. The actual size of a message depends largely on its content and the originator. As a rule of thumb, typically messages should not take up more then roughly 1k (this is the memory structure, not what you see in a network dump!). For typical linux messages, 512 bytes should be a good bet. Please also note that there is a minimal amount of memory taken for each queue entry, no matter if it is used or not. This is one pointer value, so on 32bit systems, it should typically be 4 bytes and on 64bit systems it should typically be 8 bytes. For example, the default queue size of 10,000 entries needs roughly 40k fixed overhead on a 32 bit system.

    $MainMsgQueueSize 100000 # 100,000 may be a value to handle burst traffic

    GuardTime Log Signature Provider (gt)

    Signature Provider Name:    gt

    Author: Rainer Gerhards <rgerhards@adiscon.com>

    Supported Since: since 7.3.9

    Description:

    Provides the ability to sign syslog messages via the GuardTime signature services.

    Configuration Parameters:

    Signature providers are loaded by omfile, when the provider is selected in its "sig.providerName" parameter. Parameters for the provider are given in the omfile action instance line.

    This provider creates a signature file with the same base name but the extension ".gtsig" for each log file (both for fixed-name files as well as dynafiles). Both files together form a set. So you need to archive both in order to prove integrity.

    • sig.hashFunction <Hash Algorithm>
      The following hash algorithms are currently supported:
      • SHA1
      • RIPEMD-160
      • SHA2-224
      • SHA2-256
      • SHA2-384
      • SHA2-512
    • sig.timestampService <timestamper URL>
      This provides the URL of the timestamper service. If not selected, a default server is selected. This may not necessarily be a good one for your region.
    • sig.block.sizeLimit <nbr-records>
      The maximum number of records inside a single signature block. By default, there is no size limit, so the signature is only written on file closure. Note that a signature request typically takes between one and two seconds. So signing to frequently is probably not a good idea.
    • sig.keepRecordHashes <on/off>
      Controls if record hashes are written to the .gtsig file. This enhances the ability to spot the location of a signature breach, but costs considerable disk space (65 bytes for each log record for SHA2-512 hashes, for example).
    • sig.keepTreeHashes <on/off>
      Controls if tree (intermediate) hashes are written to the .gtsig file. This enhances the ability to spot the location of a signature breach, but costs considerable disk space (a bit mire than the amount sig.keepRecordHashes requries). Note that both Tree and Record hashes can be kept inside the signature file.
    Caveats/Known Bugs:
    • currently none known

    Samples:

    This writes a log file with it's associated signature file. Default parameters are used.

    In the next sample, we use the more secure SHA2-512 hash function, sign every 10,000 records and Tree and Record hashes are kept.

    Writing Rsyslog Output Plugins

    This page is the begin of some developer documentation for writing output plugins. Doing so is quite easy (and that was a design goal), but there currently is only sparse documentation on the process available. I was tempted NOT to write this guide here because I know I will most probably not be able to write a complete guide.

    However, I finally concluded that it may be better to have same information and pointers than to have nothing.

    Getting Started and Samples

    The best to get started with rsyslog plugin development is by looking at existing plugins. All that start with "om" are output modules. That means they are primarily thought of being message sinks. In theory, however, output plugins may aggergate other functionality, too. Nobody has taken this route so far so if you would like to do that, it is highly suggested to post your plan on the rsyslog mailing list, first (so that we can offer advise).

    The rsyslog distribution tarball contains the omstdout plugin which is extremely well targeted for getting started. Just note that this plugin itself is not meant for production use. But it is very simplistic and so a really good starting point to grasp the core ideas.

    In any case, you should also read the comments in ./runtime/module-template.h. Output plugins are build based on a large set of code-generating macros. These macros handle most of the plumbing needed by the interface. As long as no special callback to rsyslog is needed (it typically is not), an output plugin does not really need to be aware that it is executed by rsyslog. As a plug-in programmer, you can (in most cases) "code as usual". However, all macros and entry points need to be provided and thus reading the code comments in the files mentioned is highly suggested.

    For testing, you need rsyslog's debugging support. Some useful information is given in "troubleshooting rsyslog from the doc set.

    Special Topics

    Threading

    Rsyslog uses massive parallel processing and multithreading. However, a plugin's entry points are guaranteed to be never called concurrently for the same action. That means your plugin must be able to be called concurrently by two or more threads, but you can be sure that for the same instance no concurrent calls happen. This is guaranteed by the interface specification and the rsyslog core guards against multiple concurrent calls. An instance, in simple words, is one that shares a single instanceData structure.

    So as long as you do not mess around with global data, you do not need to think about multithreading (and can apply a purely sequential programming methodology).

    Please note that duringt the configuraton parsing stage of execution, access to global variables for the configuration system is safe. In that stage, the core will only call sequentially into the plugin.

    Getting Message Data

    The doAction() entry point of your plugin is provided with messages to be processed. It will only be activated after filtering and all other conditions, so you do not need to apply any other conditional but can simply process the message.

    Note that you do NOT receive the full internal representation of the message object. There are various (including historical) reasons for this and, among others, this is a design decision based on security.

    Your plugin will only receive what the end user has configured in a $template statement. However, starting with 4.1.6, there are two ways of receiving the template content. The default mode, and in most cases sufficient and optimal, is to receive a single string with the expanded template. As I said, this is usually optimal, think about writing things to files, emailing content or forwarding it.

    The important philosophy is that a plugin should never reformat any of such strings - that would either remove the user's ability to fully control message formats or it would lead to duplicating code that is already present in the core. If you need some formatting that is not yet present in the core, suggest it to the rsyslog project, best done by sending a patch ;), and we will try hard to get it into the core (so far, we could accept all such suggestions - no promise, though).

    If a single string seems not suitable for your application, the plugin can also request access to the template components. The typical use case seems to be databases, where you would like to access properties via specific fields. With that mode, you receive a char ** array, where each array element points to one field from the template (from left to right). Fields start at arrray index 0 and a NULL pointer means you have reached the end of the array (the typical Unix "poor man's linked list in an array" design). Note, however, that each of the individual components is a string. It is not a date stamp, number or whatever, but a string. This is because rsyslog processes strings (from a high-level design look at it) and so this is the natural data type. Feel free to convert to whatever you need, but keep in mind that malformed packets may have lead to field contents you'd never expected...

    If you like to use the array-based parameter passing method, think that it is only available in rsyslog 4.1.6 and above. If you can accept that your plugin will not be working with previous versions, you do not need to handle pre 4.1.6 cases. However, it would be "nice" if you shut down yourself in these cases - otherwise the older rsyslog core engine will pass you a string where you expect the array of pointers, what most probably results in a segfault. To check whether or not the core supports the functionality, you can use this code sequence: 

    
BEGINmodInit()
	rsRetVal localRet;
	rsRetVal (*pomsrGetSupportedTplOpts)(unsigned long *pOpts);
	unsigned long opts;
	int bArrayPassingSupported;		/* does core support template passing as an array? */
CODESTARTmodInit
	*ipIFVersProvided = CURR_MOD_IF_VERSION; /* we only support the current interface specification */
CODEmodInit_QueryRegCFSLineHdlr
	/* check if the rsyslog core supports parameter passing code */
	bArrayPassingSupported = 0;
	localRet = pHostQueryEtryPt((uchar*)"OMSRgetSupportedTplOpts", &pomsrGetSupportedTplOpts);
	if(localRet == RS_RET_OK) {
		/* found entry point, so let's see if core supports array passing */
		CHKiRet((*pomsrGetSupportedTplOpts)(&opts));
		if(opts & OMSR_TPL_AS_ARRAY)
			bArrayPassingSupported = 1;
	} else if(localRet != RS_RET_ENTRY_POINT_NOT_FOUND) {
		ABORT_FINALIZE(localRet); /* Something else went wrong, what is not acceptable */
	}
	DBGPRINTF("omstdout: array-passing is %ssupported by rsyslog core.\n", bArrayPassingSupported ? "" : "not ");

	if(!bArrayPassingSupported) {
		DBGPRINTF("rsyslog core too old, shutting down this plug-in\n");
		ABORT_FINALIZE(RS_RET_ERR);
	}

    The code first checks if the core supports the OMSRgetSupportedTplOpts() API (which is also not present in all versions!) and, if so, queries the core if the OMSR_TPL_AS_ARRAY mode is supported. If either does not exits, the core is too old for this functionality. The sample snippet above then shuts down, but a plugin may instead just do things different. In omstdout, you can see how a plugin may deal with the situation.

    In any case, it is recommended that at least a graceful shutdown is made and the array-passing capability not blindly be used. In such cases, we can not guard the plugin from segfaulting and if the plugin (as currently always) is run within rsyslog's process space, that results in a segfault for rsyslog. So do not do this.

    Another possible mode is OMSR_TPL_AS_JSON, where instead of the template a json-c memory object tree is passed to the module. The module can extract data via json-c API calls. It MUST NOT modify the provided structure. This mode is primarily aimed at plugins that need to process tree-like data, as found for example in MongoDB or ElasticSearch.

    Batching of Messages

    Starting with rsyslog 4.3.x, batching of output messages is supported. Previously, only a single-message interface was supported.

    With the single message plugin interface, each message is passed via a separate call to the plugin. Most importantly, the rsyslog engine assumes that each call to the plugin is a complete transaction and as such assumes that messages be properly commited after the plugin returns to the engine.

    With the batching interface, rsyslog employs something along the line of "transactions". Obviously, the rsyslog core can not make non-transactional outputs to be fully transactional. But what it can is support that the output tells the core which messages have been commited by the output and which not yet. The core can than take care of those uncommited messages when problems occur. For example, if a plugin has received 50 messages but not yet told the core that it commited them, and then returns an error state, the core assumes that all these 50 messages were not written to the output. The core then requeues all 50 messages and does the usual retry processing. Once the output plugin tells the core that it is ready again to accept messages, the rsyslog core will provide it with these 50 not yet commited messages again (actually, at this point, the rsyslog core no longer knows that it is re-submiting the messages). If, in contrary, the plugin had told rsyslog that 40 of these 50 messages were commited (before it failed), then only 10 would have been requeued and resubmitted.

    In order to provide an efficient implementation, there are some (mild) constraints in that transactional model: first of all, rsyslog itself specifies the ultimate transaction boundaries. That is, it tells the plugin when a transaction begins and when it must finish. The plugin is free to commit messages in between, but it must commit all work done when the core tells it that the transaction ends. All messages passed in between a begin and end transaction notification are called a batch of messages. They are passed in one by one, just as without transaction support. Note that batch sizes are variable within the range of 1 to a user configured maximum limit. Most importantly, that means that plugins may receive batches of single messages, so they are required to commit each message individually. If the plugin tries to be "smarter" than the rsyslog engine and does not commit messages in those cases (for example), the plugin puts message stream integrity at risk: once rsyslog has notified the plugin of transacton end, it discards all messages as it considers them committed and save. If now something goes wrong, the rsyslog core does not try to recover lost messages (and keep in mind that "goes wrong" includes such uncontrollable things like connection loss to a database server). So it is highly recommended to fully abide to the plugin interface details, even though you may think you can do it better. The second reason for that is that the core engine will have configuration settings that enable the user to tune commit rate to their use-case specific needs. And, as a relief: why would rsyslog ever decide to use batches of one? There is a trivial case and that is when we have very low activity so that no queue of messages builds up, in which case it makes sense to commit work as it arrives. (As a side-note, there are some valid cases where a timeout-based commit feature makes sense. This is also under evaluation and, once decided, the core will offer an interface plus a way to preserve message stream integrity for properly-crafted plugins).

    The second restriction is that if a plugin makes commits in between (what is perfectly legal) those commits must be in-order. So if a commit is made for message ten out of 50, this means that messages one to nine are also commited. It would be possible to remove this restriction, but we have decided to deliberately introduce it to simpify things.

    Output Plugin Transaction Interface

    In order to keep compatible with existing output plugins (and because it introduces no complexity), the transactional plugin interface is build on the traditional non-transactional one. Well... actually the traditional interface was transactional since its introduction, in the sense that each message was processed in its own transaction.

    So the current doAction() entry point can be considered to have this structure (from the transactional interface point of view): 

    
doAction()
    {
    beginTransaction()
    ProcessMessage()
    endTransaction()
    }

    For the transactional interface, we now move these implicit beginTransaction() and endTransaction(() call out of the message processing body, resulting is such a structure: 

    
beginTransaction()
    {
    /* prepare for transaction */
    }

doAction()
    {
    ProcessMessage()
    /* maybe do partial commits */
    }

endTransaction()
    {
    /* commit (rest of) batch */
    }

    And this calling structure actually is the transactional interface! It is as simple as this. For the new interface, the core calls a beginTransaction() entry point inside the plugin at the start of the batch. Similarly, the core call endTransaction() at the end of the batch. The plugin must implement these entry points according to its needs.

    But how does the core know when to use the old or the new calling interface? This is rather easy: when loading a plugin, the core queries the plugin for the beginTransaction() and endTransaction() entry points. If the plugin supports these, the new interface is used. If the plugin does not support them, the old interface is used and rsyslog implies that a commit is done after each message. Note that there is no special "downlevel" handling necessary to support this. In the case of the non-transactional interface, rsyslog considers each completed call to doAction as partial commit up to the current message. So implementation inside the core is very straightforward.

    Actually, we recommend that the transactional entry points only be defined by those plugins that actually need them. All others should not define them in which case the default commit behaviour inside rsyslog will apply (thus removing complexity from the plugin).

    In order to support partial commits, special return codes must be defined for doAction. All those return codes mean that processing completed successfully. But they convey additional information about the commit status as follows:

    RS_RET_OK The record and all previous inside the batch has been commited. Note: this definition is what makes integrating plugins without the transaction being/end calls so easy - this is the traditional "success" return state and if every call returns it, there is no need for actually calling endTransaction(), because there is no transaction open).
    RS_RET_DEFER_COMMIT The record has been processed, but is not yet commited. This is the expected state for transactional-aware plugins.
    RS_RET_PREVIOUS_COMMITTED The previous record inside the batch has been committed, but the current one not yet. This state is introduced to support sources that fill up buffers and commit once a buffer is completely filled. That may occur halfway in the next record, so it may be important to be able to tell the engine the everything up to the previouos record is commited

    Note that the typical calling cycle is beginTransaction(), followed by n times doAction() followed by endTransaction(). However, if either beginTransaction() or doAction() return back an error state (including RS_RET_SUSPENDED), then the transaction is considered aborted. In result, the remaining calls in this cycle (e.g. endTransaction()) are never made and a new cycle (starting with beginTransaction() is begun when processing resumes. So an output plugin must expect and handle those partial cycles gracefully.

    The question remains how can a plugin know if the core supports batching? First of all, even if the engine would not know it, the plugin would return with RS_RET_DEFER_COMMIT, what then would be treated as an error by the engine. This would effectively disable the output, but cause no further harm (but may be harm enough in itself).

    The real solution is to enable the plugin to query the rsyslog core if this feature is supported or not. At the time of the introduction of batching, no such query-interface exists. So we introduce it with that release. What the means is if a rsyslog core can not provide this query interface, it is a core that was build before batching support was available. So the absence of a query interface indicates that the transactional interface is not available. One might now be tempted the think there is no need to do the actual check, but is is recommended to ask the rsyslog engine explicitely if the transactional interface is present and will be honored. This enables us to create versions in the future which have, for whatever reason we do not yet know, no support for this interface.

    The logic to do these checks is contained in the INITChkCoreFeature macro, which can be used as follows: 

    
INITChkCoreFeature(bCoreSupportsBatching, CORE_FEATURE_BATCHING);

    Here, bCoreSupportsBatching is a plugin-defined integer which after execution is 1 if batches (and thus the transational interface) is supported and 0 otherwise. CORE_FEATURE_BATCHING is the feature we are interested in. Future versions of rsyslog may contain additional feature-test-macros (you can see all of them in ./runtime/rsyslog.h).

    Note that the ompsql output plugin supports transactional mode in a hybrid way and thus can be considered good example code.

    Open Issues

    • Processing errors handling
    • reliable re-queue during error handling and queue termination

    Licensing

    From the rsyslog point of view, plugins constitute separate projects. As such, we think plugins are not required to be compatible with GPLv3. However, this is no legal advise. If you intend to release something under a non-GPLV3 compatible license it is probably best to consult with your lawyer.

    Most importantly, and this is definite, the rsyslog team does not expect or require you to contribute your plugin to the rsyslog project (but of course we are happy if you do).

    Turning Lanes and Rsyslog Queues - an Analogy

    If there is a single object absolutely vital to understanding the way rsyslog works, this object is queues. Queues offer a variety of services, including support for multithreading. While there is elaborate in-depth documentation on the ins and outs of rsyslog queues, some of the concepts are hard to grasp even for experienced people. I think this is because rsyslog uses a very high layer of abstraction which includes things that look quite unnatural, like queues that do not actually queue...

    With this document, I take a different approach: I will not describe every specific detail of queue operation but hope to be able to provide the core idea of how queues are used in rsyslog by using an analogy. I will compare the rsyslog data flow with real-life traffic flowing at an intersection.

    But first let's set the stage for the rsyslog part. The graphic below describes the data flow inside rsyslog:

    rsyslog data flow

    Note that there is a video tutorial available on the data flow. It is not perfect, but may aid in understanding this picture.

    For our needs, the important fact to know is that messages enter rsyslog on "the left side" (for example, via UDP), are being preprocessed, put into the so-called main queue, taken off that queue, be filtered and be placed into one or several action queues (depending on filter results). They leave rsyslog on "the right side" where output modules (like the file or database writer) consume them.

    So there are always two stages where a message (conceptually) is queued - first in the main queue and later on in n action specific queues (with n being the number of actions that the message in question needs to be processed by, what is being decided by the "Filter Engine"). As such, a message will be in at least two queues during its lifetime (with the exception of messages being discarded by the queue itself, but for the purpose of this document, we will ignore that possibility).

    Also, it is vitally important to understand that each action has a queue sitting in front of it. If you have dug into the details of rsyslog configuration, you have probably seen that a queue mode can be set for each action. And the default queue mode is the so-called "direct mode", in which "the queue does not actually enqueue data". That sounds silly, but is not. It is an important abstraction that helps keep the code clean.

    To understand this, we first need to look at who is the active component. In our data flow, the active part always sits to the left of the object. For example, the "Preprocessor" is being called by the inputs and calls itself into the main message queue. That is, the queue receiver is called, it is passive. One might think that the "Parser & Filter Engine" is an active component that actively pulls messages from the queue. This is wrong! Actually, it is the queue that has a pool of worker threads, and these workers pull data from the queue and then call the passively waiting Parser and Filter Engine with those messages. So the main message queue is the active part, the Parser and Filter Engine is passive.

    Let's now try an analogy analogy for this part: Think about a TV show. The show is produced in some TV studio, from there sent (actively) to a radio tower. The radio tower passively receives from the studio and then actively sends out a signal, which is passively received by your TV set. In our simplified view, we have the following picture:

    rsyslog queues and TV analogy

    The lower part of the picture lists the equivalent rsyslog entities, in an abstracted way. Every queue has a producer (in the above sample the input) and a consumer (in the above sample the Parser and Filter Engine). Their active and passive functions are equivalent to the TV entities that are listed on top of the rsyslog entity. For example, a rsyslog consumer can never actively initiate reception of a message in the same way a TV set cannot actively "initiate" a TV show - both can only "handle" (display or process) what is sent to them.

    Now let's look at the action queues: here, the active part, the producer, is the Parser and Filter Engine. The passive part is the Action Processor. The later does any processing that is necessary to call the output plugin, in particular it processes the template to create the plugin calling parameters (either a string or vector of arguments). From the action queue's point of view, Action Processor and Output form a single entity. Again, the TV set analogy holds. The Output does not actively ask the queue for data, but rather passively waits until the queue itself pushes some data to it.

    Armed with this knowledge, we can now look at the way action queue modes work. My analogy here is a junction, as shown below (note that the colors in the pictures below are not related to the colors in the pictures above!):

    This is a very simple real-life traffic case: one road joins another. We look at traffic on the straight road, here shown by blue and green arrows. Traffic in the opposing direction is shown in blue. Traffic flows without any delays as long as nobody takes turns. To be more precise, if the opposing traffic takes a (right) turn, traffic still continues to flow without delay. However, if a car in the red traffic flow intends to do a (left, then) turn, the situation changes:

    The turning car is represented by the green arrow. It cannot turn unless there is a gap in the "blue traffic stream". And as this car blocks the roadway, the remaining traffic (now shown in red, which should indicate the block condition), must wait until the "green" car has made its turn. So a queue will build up on that lane, waiting for the turn to be completed. Note that in the examples below I do not care that much about the properties of the opposing traffic. That is, because its structure is not really important for what I intend to show. Think about the blue arrow as being a traffic stream that most of the time blocks left-turners, but from time to time has a gap that is sufficiently large for a left-turn to complete.

    Our road network designers know that this may be unfortunate, and for more important roads and junctions, they came up with the concept of turning lanes:

    Now, the car taking the turn can wait in a special area, the turning lane. As such, the "straight" traffic is no longer blocked and can flow in parallel to the turning lane (indicated by a now-green-again arrow).

    However, the turning lane offers only finite space. So if too many cars intend to take a left turn, and there is no gap in the "blue" traffic, we end up with this well-known situation:

    The turning lane is now filled up, resulting in a tailback of cars intending to left turn on the main driving lane. The end result is that "straight" traffic is again being blocked, just as in our initial problem case without the turning lane. In essence, the turning lane has provided some relief, but only for a limited amount of cars. Street system designers now try to weight cost vs. benefit and create (costly) turning lanes that are sufficiently large to prevent traffic jams in most, but not all cases.

    Now let's dig a bit into the mathematical properties of turning lanes. We assume that cars all have the same length. So, units of cars, the length is alsways one (which is nice, as we don't need to care about that factor any longer ;)). A turning lane has finite capacity of n cars. As long as the number of cars wanting to take a turn is less than or eqal to n, "straigth traffic" is not blocked (or the other way round, traffic is blocked if at least n + 1 cars want to take a turn!). We can now find an optimal value for n: it is a function of the probability that a car wants to turn and the cost of the turning lane (as well as the probability there is a gap in the "blue" traffic, but we ignore this in our simple sample). If we start from some finite upper bound of n, we can decrease n to a point where it reaches zero. But let's first look at n = 1, in which case exactly one car can wait on the turning lane. More than one car, and the rest of the traffic is blocked. Our everyday logic indicates that this is actually the lowest boundary for n.

    In an abstract view, however, n can be zero and that works nicely. There still can be n cars at any given time on the turning lane, it just happens that this means there can be no car at all on it. And, as usual, if we have at least n + 1 cars wanting to turn, the main traffic flow is blocked. True, but n + 1 = 0 + 1 = 1 so as soon as there is any car wanting to take a turn, the main traffic flow is blocked (remember, in all cases, I assume no sufficiently large gaps in the opposing traffic).

    This is the situation our everyday perception calls "road without turning lane". In my math model, it is a "road with turning lane of size 0". The subtle difference is important: my math model guarantees that, in an abstract sense, there always is a turning lane, it may just be too short. But it exists, even though we don't see it. And now I can claim that even in my small home village, all roads have turning lanes, which is rather impressive, isn't it? ;)

    And now we finally have arrived at rsyslog's queues! Rsyslog action queues exists for all actions just like all roads in my village have turning lanes! And as in this real-life sample, it may be hard to see the action queues for that reason. In rsyslog, the "direct" queue mode is the equivalent to the 0-sized turning lane. And actions queues are the equivalent to turning lanes in general, with our real-life n being the maximum queue size. The main traffic line (which sometimes is blocked) is the equivalent to the main message queue. And the periods without gaps in the opposing traffic are equivalent to execution time of an action. In a rough sketch, the rsyslog main and action queues look like in the following picture.

    We need to read this picture from right to left (otherwise I would need to redo all the graphics ;)). In action 3, you see a 0-sized turning lane, aka an action queue in "direct" mode. All other queues are run in non-direct modes, but with different sizes greater than 0.

    Let us first use our car analogy: Assume we are in a car on the main lane that wants to take turn into the "action 4" road. We pass action 1, where a number of cars wait in the turning lane and we pass action 2, which has a slightly smaller, but still not filled up turning lane. So we pass that without delay, too. Then we come to "action 3", which has no turning lane. Unfortunately, the car in front of us wants to turn left into that road, so it blocks the main lane. So, this time we need to wait. An observer standing on the sidewalk may see that while we need to wait, there are still some cars in the "action 4" turning lane. As such, even though no new cars can arrive on the main lane, cars still turn into the "action 4" lane. In other words, an observer standing in "action 4" road is unable to see that traffic on the main lane is blocked.

    Now on to rsyslog: Other than in the real-world traffic example, messages in rsyslog can - at more or less the same time - "take turns" into several roads at once. This is done by duplicating the message if the road has a non-zero-sized "turning lane" - or in rsyslog terms a queue that is running in any non-direct mode. If so, a deep copy of the message object is made, that placed into the action queue and then the initial message proceeds on the "main lane". The action queue then pushes the duplicates through action processing. This is also the reason why a discard action inside a non-direct queue does not seem to have an effect. Actually, it discards the copy that was just created, but the original message object continues to flow.

    In action 1, we have some entries in the action queue, as we have in action 2 (where the queue is slightly shorter). As we have seen, new messages pass action one and two almost instantaneously. However, when a messages reaches action 3, its flow is blocked. Now, message processing must wait for the action to complete. Processing flow in a direct mode queue is something like a U-turn:

    message processing in an rsyslog action queue in direct mode

    The message starts to execute the action and once this is done, processing flow continues. In a real-life analogy, this may be the route of a delivery man who needs to drop a parcel in a side street before he continues driving on the main route. As a side-note, think of what happens with the rest of the delivery route, at least for today, if the delivery truck has a serious accident in the side street. The rest of the parcels won't be delivered today, will they? This is exactly how the discard action works. It drops the message object inside the action and thus the message will no longer be available for further delivery - but as I said, only if the discard is done in a direct mode queue (I am stressing this example because it often causes a lot of confusion).

    Back to the overall scenario. We have seen that messages need to wait for action 3 to complete. Does this necessarily mean that at the same time no messages can be processed in action 4? Well, it depends. As in the real-life scenario, action 4 will continue to receive traffic as long as its action queue ("turn lane") is not drained. In our drawing, it is not. So action 4 will be executed while messages still wait for action 3 to be completed.

    Now look at the overall picture from a slightly different angle:

    message processing in an rsyslog action queue in direct mode

    The number of all connected green and red arrows is four - one each for action 1, 2 and 3 (this one is dotted as action 4 was a special case) and one for the "main lane" as well as action 3 (this one contains the sole red arrow). This number is the lower bound for the number of threads in rsyslog's output system ("right-hand part" of the main message queue)! Each of the connected arrows is a continuous thread and each "turn lane" is a place where processing is forked onto a new thread. Also, note that in action 3 the processing is carried out on the main thread, but not in the non-direct queue modes.

    I have said this is "the lower bound for the number of threads...". This is with good reason: the main queue may have more than one worker thread (individual action queues currently do not support this, but could do in the future - there are good reasons for that, too but exploring why would finally take us away from what we intend to see). Note that you configure an upper bound for the number of main message queue worker threads. The actual number varies depending on a lot of operational variables, most importantly the number of messages inside the queue. The number t_m of actually running threads is within the integer-interval [0,confLimit] (with confLimit being the operator configured limit, which defaults to 5). Output plugins may have more than one thread created by themselves. It is quite unusual for an output plugin to create such threads and so I assume we do not have any of these. Then, the overall number of threads in rsyslog's filtering and output system is t_total = t_m + number of actions in non-direct modes. Add the number of inputs configured to that and you have the total number of threads running in rsyslog at a given time (assuming again that inputs utilize only one thread per plugin, a not-so-safe assumption).

    A quick side-note: I gave the lower bound for t_m as zero, which is somewhat in contrast to what I wrote at the begin of the last paragraph. Zero is actually correct, because rsyslog stops all worker threads when there is no work to do. This is also true for the action queues. So the ultimate lower bound for a rsyslog output system without any work to carry out actually is zero. But this bound will never be reached when there is continuous flow of activity. And, if you are curios: if the number of workers is zero, the worker wakeup process is actually handled within the threading context of the "left-hand-side" (or producer) of the queue. After being started, the worker begins to play the active queue component again. All of this, of course, can be overridden with configuration directives.

    When looking at the threading model, one can simply add n lanes to the main lane but otherwise retain the traffic analogy. This is a very good description of the actual process (think what this means to the "turning lanes"; hint: there still is only one per action!).

    Let's try to do a warp-up: I have hopefully been able to show that in rsyslog, an action queue "sits in front of" each output plugin. Messages are received and flow, from input to output, over various stages and two level of queues to the outputs. Actions queues are always present, but may not easily be visible when in direct mode (where no actual queuing takes place). The "road junction with turning lane" analogy well describes the way - and intent - of the various queue levels in rsyslog.

    On the output side, the queue is the active component, not the consumer. As such, the consumer cannot ask the queue for anything (like n number of messages) but rather is activated by the queue itself. As such, a queue somewhat resembles a "living thing" whereas the outputs are just tools that this "living thing" uses.

    Note that I left out a couple of subtleties, especially when it comes to error handling and terminating a queue (you hopefully have now at least a rough idea why I say "terminating a queue" and not "terminating an action" - who is the "living thing"?). An action returns a status to the queue, but it is the queue that ultimately decides which messages can finally be considered processed and which not. Please note that the queue may even cancel an output right in the middle of its action. This happens, if configured, if an output needs more than a configured maximum processing time and is a guard condition to prevent slow outputs from deferring a rsyslog restart for too long. Especially in this case re-queuing and cleanup is not trivial. Also, note that I did not discuss disk-assisted queue modes. The basic rules apply, but there are some additional constraints, especially in regard to the threading model. Transitioning between actual disk-assisted mode and pure-in-memory-mode (which is done automatically when needed) is also far from trivial and a real joy for an implementer to work on ;).

    If you have not done so before, it may be worth reading the rsyslog queue user's guide, which most importantly lists all the knobs you can turn to tweak queue operation.

    Recording the Priority of Syslog Messages

    Written by Rainer Gerhards (2007-06-18)

    Abstract

    The so-called priority (PRI) is very important in syslog messages, because almost all filtering in syslog.conf is based on it. However, many syslogds (including the Linux stock sysklogd) do not provide a way to record that value. In this article, I'll give a brief overview of how PRI can be written to a log file.

    Background

    The PRI value is a combination of so-called severity and facility. The facility indicates where the message originated from (e.g. kernel, mail subsystem) while the severity provides a glimpse of how important the message might be (e.g. error or informational). Be careful with these values: they are in no way consistent across applications (especially severity). However, they still form the basis of most filtering in syslog.conf. For example, the directive (aka "selector line)

    mail.* /var/log/mail.log

    means that messages with the mail facility should be stored to /var/log/mail.log, no matter which severity indicator they have (that is telling us the asterisk). If you set up complex conditions, it can be annoying to find out which PRI value a specific syslog message has. Most stock syslogds do not provide any way to record them.

    How is it done?

    With rsyslog, PRI recording is simple. All you need is the correct template. Even if you do not use rsyslog on a regular basis, it might be a handy tool for finding out the priority.

    Rsyslog provides a flexible system to specify the output formats. It is template-based. A template with the traditional syslog format looks as follows:

    $template TraditionalFormat,"%timegenerated% %HOSTNAME% %syslogtag%%msg:::drop-last-lf%\n"

    The part in quotes is the output formats. Things between percent-signs are so-called messages properties. They are replaced with the respective content from the syslog message when output is written. Everything outside of the percent signs is literal text, which is simply written as specified.

    Thankfully, rsyslog provides message properties for the priority. These are called "PRI", "syslogfacility" and "syslogpriority" (case is important!). They are numerical values. Starting with rsyslog 1.13.4, there is also a property "pri-text", which contains the priority in friendly text format (e.g. "syslog.info"). For the rest of this article, I assume that you run version 1.13.4 or higher.

    Recording the priority is now a simple matter of adding the respective field to the template. It now looks like this:

    $template TraditionalFormatWithPRI,"%pri-text%: %timegenerated% %HOSTNAME% %syslogtag%%msg:::drop-last-lf%\n"

    Now we have the right template - but how to write it to a file? You probably have a line like this in your syslog.conf:

    *.* -/var/log/messages.log

    It does not specify a template. Consequently, rsyslog uses the traditional format. In order to use some other format, simply specify the template after the semicolon:

    *.* -/var/log/messages.log;TraditionalFormatWithPRI

    That's all you need to do. There is one common pitfall: you need to define the template before you use it in a selector line. Otherwise, you will receive an error.

    Once you have applied the changes, you need to restart rsyslogd. It will then pick the new configuration.

    What if I do not want rsyslogd to be the standard syslogd?

    If you do not want to switch to rsyslog, you can still use it as a setup aid. A little bit of configuration is required.

    1. Download, make and install rsyslog
    2. copy your syslog.conf over to rsyslog.conf
    3. add the template described above to it; select the file that should use it
    4. stop your regular syslog daemon for the time being
    5. run rsyslogd (you may even do this interactively by calling it with the -n additional option from a shell)
    6. stop rsyslogd (press ctrl-c when running interactively)
    7. restart your regular syslogd

    That's it - you can now review the priorities.

    Below is some sample data created with the template specified above. Note the priority recording at the start of each line.

    Systemd Journal Input Module

    Module Name:    imjournal

    Author: Milan Bartos <mbartos@redhat.com>

    Description:

    Provides the ability to import structured log messages from systemd journal to syslog.

    Note that this module reads the journal database, what is considered a relativly performance-intense operation. As such, the performance of a configuration utilizing this module may be notably slower then when using imuxsock. The journal provides imuxsock with a copy of all "classical" syslog messages, however, it does not provide structured data. If the latter is needed, imjournal must be used. Otherwise, imjournal may be simply replaced by imuxsock.

    We suggest to check out our short presentation on rsyslog journal integration to learn more details of anticipated use cases.

    Warning: Some versions of systemd journal have problems with database corruption, which leads to the journal to return the same data endlessly in a thight loop. This results in massive message duplication inside rsyslog probably resulting in a denial-of-service when the system ressouces get exhausted. This can be somewhat mitigated by using proper rate-limiters, but even then there are spikes of old data which are endlessly repeated. By default, ratelimiting is activated and permits to process 20,000 messages within 10 minutes, what should be well enough for most use cases. If insufficient, use the parameters described below to adjust the permitted volume. It is strongly recommended to use this plugin only if there is hard need to do so.

    Configuration Directives:

    Module Directives

    • PersistStateInterval number-of-messages
      This is a global setting. It specifies how often should the journal state be persisted. The persists happens after each number-of-messages. This option is useful for rsyslog to start reding from the last journal message it read.
    • StateFile /path/to/file
      This is a global setting. It specifies where the state file for persisting journal state is located.
    • ratelimit.interval seconds (default: 600)
      Specifies the interval in seconds onto which rate-limiting is to be applied. If more than ratelimit.burst messages are read during that interval, further messages up to the end of the interval are discarded. The number of messages discarded is emitted at the end of the interval (if there were any discards).
      Setting this to value zero turns off ratelimiting. Note that it is not recommended to turn of ratelimiting, except that you know for sure journal database entries will never be corrupted. Without ratelimiting, a corrupted systemd journal database may cause a kind of denial of service (we are stressing this point as multiple users have reported us such problems with the journal database - information current as of June 2013).
    • ratelimit.burst messages (default: 20000)
      Specifies the maximum number of messages that can be emitted within the ratelimit.interval interval. For futher information, see description there.
    • IgnorePreviousMessages [off/on]
      This option specifies whether imjournal should ignore messages currently in journal and read only new messages. This option is only used when there is no StateFile to avoid message loss.
    Caveats/Known Bugs:

    • As stated above, a corrupted systemd journal database can cause major problems, depending on what the corruption results in. This is beyond the control of the rsyslog team.

    Sample:

    The following example shows pulling structured imjournal messages and saving them into /var/log/ceelog.

    UDP Syslog Input Module

    Module Name:    imudp

    Author: Rainer Gerhards <rgerhards@adiscon.com>

    Multi-Ruleset Support: since 5.3.2

    Description:

    Provides the ability to receive syslog messages via UDP.

    Multiple receivers may be configured by specifying multiple input actions.

    Configuration Parameters:

    Module Parameters:

    • TimeRequery <nbr-of-times>
      this is a performance optimization. Getting the system time is very costly. With this setting, imudp can be instructed to obtain the precise time only once every n-times. This logic is only activated if messages come in at a very fast rate, so doing less frequent time calls should usually be acceptable. The default value is two, because we have seen that even without optimization the kernel often returns twice the identical time. You can set this value as high as you like, but do so at your own risk. The higher the value, the less precise the timestamp.
    • SchedulingPolicy <rr/fifo/other>
      Can be used the set the scheduler priority, if the necessary functionality is provided by the platform. Most useful to select "fifo" for real-time processing under Linux (and thus reduce chance of packet loss).
    • SchedulingPriority <number>
      Scheduling priority to use.

    Input Parameters:

    • Address <IP>
      local IP address (or name) the UDP listens should bind to
    • Port <port>
      default 514, start UDP server on this port. Either a single port can be specified or an array of ports. If multiple ports are specified, a listener will be automatically started for each port. Thus, no additional inputs need to be configured.
      Single port: Port="514"
      Array of ports: Port=["514","515","10514","..."]
    • Ruleset <ruleset>
      Binds the listener to a specific ruleset.
    • RateLimit.Interval [number] - (available since 7.3.1) specifies the rate-limiting interval in seconds. Default value is 0, which turns off rate limiting. Set it to a number of seconds (5 recommended) to activate rate-limiting.
    • RateLimit.Burst [number] - (available since 7.3.1) specifies the rate-limiting burst in number of messages. Default is 10,000.
    • InputName [name] - (available since 7.3.9) specifies the value of the inputname. In older versions, this was always "imudp" for all listeners, which still i the default. Starting with 7.3.9 it can be set to different values for each listener. Note that when a single input statement defines multipe listner ports, the inputname will be the same for all of them. If you want to differentiate in that case, use "InputName.AppendPort" to make them unique. Note that the "InputName" parameter can be an empty string. In that case, the corresponding inputname property will obviously also be the empty string. This is primarily meant to be used togehter with "InputName.AppendPort" to set the inputname equal to the port.
    • InputName.AppendPort [on/off] - (available since 7.3.9) appends the port the the inputname. Note that when no inputname is specified, the default of "imudp" is used and the port is appended to that default. So, for example, a listner port of 514 in that case will lead to an inputname of "imudp514". The ability to append a port is most useful when multiple ports are defined for a single input and each of the inputnames shall be unique. Note that there currently is no differentiation between IPv4/v6 listeners on the same port.
    Caveats/Known Bugs:
    • Scheduling parameters are set after privileges have been dropped. In most cases, this means that setting them will not be possible after privilege drop. This may be worked around by using a sufficiently-privileged user account.

    Samples:

    This sets up an UPD server on port 514:

    In the next example, we set up three listeners at ports 10514, 10515 and 10516 and assign a listner name of "udp" to it, followed by the port number:

    The next example is almost equal to the previous one, but now the inputname property will just be set to the port number. So if a message was received on port 10515, the input name will be "10515" in this example whereas it was "udp10515" in the previous one. Note that to do that we set the inputname to the empty string.

    Legacy Configuration Directives:

    Multiple receivers may be configured by specifying $UDPServerRun multiple times.

    • $UDPServerAddress <IP>
      equivalent to: Address
    • $UDPServerRun <port>
      equivalent to: Port
    • $UDPServerTimeRequery <nbr-of-times>
      equivalent to: TimeRequery
    • $InputUDPServerBindRuleset <ruleset>
      equivalent to: Ruleset
    • $IMUDPSchedulingPolicy <rr/fifo/other> Available since 4.7.4+, 5.7.3+, 6.1.3+.
      equivalent to: SchedulingPolicy
    • $IMUDPSchedulingPriority <number> Available since 4.7.4+, 5.7.3+, 6.1.3+.
      equivalent to: SchedulingPriority

    Understanding rsyslog Queues

    Rsyslog uses queues whenever two activities need to be loosely coupled. With a queue, one part of the system "produces" something while another part "consumes" this something. The "something" is most often syslog messages, but queues may also be used for other purposes.

    This document provides a good insight into technical details, operation modes and implications. In addition to it, an rsyslog queue concepts overview document exists which tries to explain queues with the help of some analogies. This may probably be a better place to start reading about queues. I assume that once you have understood that document, the material here will be much easier to grasp and look much more natural.

    The most prominent example is the main message queue. Whenever rsyslog receives a message (e.g. locally, via UDP, TCP or in whatever else way), it places these messages into the main message queue. Later, it is dequeued by the rule processor, which then evaluates which actions are to be carried out. In front of each action, there is also a queue, which potentially de-couples the filter processing from the actual action (e.g. writing to file, database or forwarding to another host).

    Where are Queues Used?

    Currently, queues are used for the main message queue and for the actions.

    There is a single main message queue inside rsyslog. Each input module delivers messages to it. The main message queue worker filters messages based on rules specified in rsyslog.conf and dispatches them to the individual action queues. Once a message is in an action queue, it is deleted from the main message queue.

    There are multiple action queues, one for each configured action. By default, these queues operate in direct (non-queueing) mode. Action queues are fully configurable and thus can be changed to whatever is best for the given use case.

    Future versions of rsyslog will most probably utilize queues at other places, too.

    Wherever "<object>"  is used in the config file statements, substitute "<object>" with either "MainMsg" or "Action". The former will set main message queue parameters, the later parameters for the next action that will be created. Action queue parameters can not be modified once the action has been specified. For example, to tell the main message queue to save its content on shutdown, use $MainMsgQueueSaveOnShutdown on".

    If the same parameter is specified multiple times before a queue is created, the last one specified takes precedence. The main message queue is created after parsing the config file and all of its potential includes. An action queue is created each time an action selector is specified. Action queue parameters are reset to default after an action queue has been created (to provide a clean environment for the next action).

    Not all queues necessarily support the full set of queue configuration parameters, because not all are applicable. For example, in current output module design, actions do not support multi-threading. Consequently, the number of worker threads is fixed to one for action queues and can not be changed.

    Queue Modes

    Rsyslog supports different queue modes, some with submodes. Each of them has specific advantages and disadvantages. Selecting the right queue mode is quite important when tuning rsyslogd. The queue mode (aka "type") is set via the "$<object>QueueType" config directive.

    Direct Queues

    Direct queues are non-queuing queues. A queue in direct mode does neither queue nor buffer any of the queue elements but rather passes the element directly (and immediately) from the producer to the consumer. This sounds strange, but there is a good reason for this queue type.

    Direct mode queues allow to use queues generically, even in places where queuing is not always desired. A good example is the queue in front of output actions. While it makes perfect sense to buffer forwarding actions or database writes, it makes only limited sense to build up a queue in front of simple local file writes. Yet, rsyslog still has a queue in front of every action. So for file writes, the queue mode can simply be set to "direct", in which case no queuing happens.

    Please note that a direct queue also is the only queue type that passes back the execution return code (success/failure) from the consumer to the producer. This, for example, is needed for the backup action logic. Consequently, backup actions require the to-be-checked action to use a "direct" mode queue.

    To create a direct queue, use the "$<object>QueueType Direct" config directive.

    Disk Queues

    Disk queues use disk drives for buffering. The important fact is that the always use the disk and do not buffer anything in memory. Thus, the queue is ultra-reliable, but by far the slowest mode. For regular use cases, this queue mode is not recommended. It is useful if log data is so important that it must not be lost, even in extreme cases.

    When a disk queue is written, it is done in chunks. Each chunk receives its individual file. Files are named with a prefix (set via the "$<object>QueueFilename" config directive) and followed by a 7-digit number (starting at one and incremented for each file). Chunks are 10mb by default, a different size can be set via the"$<object>QueueMaxFileSize" config directive. Note that the size limit is not a sharp one: rsyslog always writes one complete queue entry, even if it violates the size limit. So chunks are actually a little but (usually less than 1k) larger then the configured size. Each chunk also has a different size for the same reason. If you observe different chunk sizes, you can relax: this is not a problem.

    Writing in chunks is used so that processed data can quickly be deleted and is free for other uses - while at the same time keeping no artificial upper limit on disk space used. If a disk quota is set (instructions further below), be sure that the quota/chunk size allows at least two chunks to be written. Rsyslog currently does not check that and will fail miserably if a single chunk is over the quota.

    Creating new chunks costs performance but provides quicker ability to free disk space. The 10mb default is considered a good compromise between these two. However, it may make sense to adapt these settings to local policies. For example, if a disk queue is written on a dedicated 200gb disk, it may make sense to use a 2gb (or even larger) chunk size.

    Please note, however, that the disk queue by default does not update its housekeeping structures every time it writes to disk. This is for performance reasons. In the event of failure, data will still be lost (except when manually is mangled with the file structures). However, disk queues can be set to write bookkeeping information on checkpoints (every n records), so that this can be made ultra-reliable, too. If the checkpoint interval is set to one, no data can be lost, but the queue is exceptionally slow.

    Each queue can be placed on a different disk for best performance and/or isolation. This is currently selected by specifying different $WorkDirectory config directives before the queue creation statement.

    To create a disk queue, use the "$<object>QueueType Disk" config directive. Checkpoint intervals can be specified via "$<object>QueueCheckpointInterval", with 0 meaning no checkpoints. Note that disk-based queues can be made very reliable by issuing a (f)sync after each write operation. Starting with version 4.3.2, this can be requested via "<object>QueueSyncQueueFiles on/off with the default being off. Activating this option has a performance penalty, so it should not be turned on without reason.

    In-Memory Queues

    In-memory queue mode is what most people have on their mind when they think about computing queues. Here, the enqueued data elements are held in memory. Consequently, in-memory queues are very fast. But of course, they do not survive any program or operating system abort (what usually is tolerable and unlikely). Be sure to use an UPS if you use in-memory mode and your log data is important to you. Note that even in-memory queues may hold data for an infinite amount of time when e.g. an output destination system is down and there is no reason to move the data out of memory (lying around in memory for an extended period of time is NOT a reason). Pure in-memory queues can't even store queue elements anywhere else than in core memory.

    There exist two different in-memory queue modes: LinkedList and FixedArray. Both are quite similar from the user's point of view, but utilize different algorithms.

    A FixedArray queue uses a fixed, pre-allocated array that holds pointers to queue elements. The majority of space is taken up by the actual user data elements, to which the pointers in the array point. The pointer array itself is comparatively small. However, it has a certain memory footprint even if the queue is empty. As there is no need to dynamically allocate any housekeeping structures, FixedArray offers the best run time performance (uses the least CPU cycle). FixedArray is best if there is a relatively low number of queue elements expected and performance is desired. It is the default mode for the main message queue (with a limit of 10,000 elements).

    A LinkedList queue is quite the opposite. All housekeeping structures are dynamically allocated (in a linked list, as its name implies). This requires somewhat more runtime processing overhead, but ensures that memory is only allocated in cases where it is needed. LinkedList queues are especially well-suited for queues where only occasionally a than-high number of elements need to be queued. A use case may be occasional message burst. Memory permitting, it could be limited to e.g. 200,000 elements which would take up only memory if in use. A FixedArray queue may have a too large static memory footprint in such cases.

    In general, it is advised to use LinkedList mode if in doubt. The processing overhead compared to FixedArray is low and may be outweigh by the reduction in memory use. Paging in most-often-unused pointer array pages can be much slower than dynamically allocating them.

    To create an in-memory queue, use the "$<object>QueueType LinkedList" or  "$<object>QueueType FixedArray" config directive.

    Disk-Assisted Memory Queues

    If a disk queue name is defined for in-memory queues (via $<object>QueueFileName), they automatically become "disk-assisted" (DA). In that mode, data is written to disk (and read back) on an as-needed basis.

    Actually, the regular memory queue (called the "primary queue") and a disk queue (called the "DA queue") work in tandem in this mode. Most importantly, the disk queue is activated if the primary queue is full or needs to be persisted on shutdown. Disk-assisted queues combine the advantages of pure memory queues with those of  pure disk queues. Under normal operations, they are very fast and messages will never touch the disk. But if there is need to, an unlimited amount of messages can be buffered (actually limited by free disk space only) and data can be persisted between rsyslogd runs.

    With a DA-queue, both disk-specific and in-memory specific configuration parameters can be set. From the user's point of view, think of a DA queue like a "super-queue" which does all within a single queue [from the code perspective, there is some specific handling for this case, so it is actually much like a single object].

    DA queues are typically used to de-couple potentially long-running and unreliable actions (to make them reliable). For example, it is recommended to use a disk-assisted linked list in-memory queue in front of each database and "send via tcp" action. Doing so makes these actions reliable and de-couples their potential low execution speed from the rest of your rules (e.g. the local file writes). There is a howto on massive database inserts which nicely describes this use case. It may even be a good read if you do not intend to use databases.

    With DA queues, we do not simply write out everything to disk and then run as a disk queue once the in-memory queue is full. A much smarter algorithm is used, which involves a "high watermark" and a "low watermark". Both specify numbers of queued items. If the queue size reaches high watermark elements, the queue begins to write data elements to disk. It does so until it reaches the low water mark elements. At this point, it stops writing until either high water mark is reached again or the on-disk queue becomes empty, in which case the queue reverts back to in-memory mode, only. While holding at the low watermark, new elements are actually enqueued in memory. They are eventually written to disk, but only if the high water mark is ever reached again. If it isn't, these items never touch the disk. So even when a queue runs disk-assisted, there is in-memory data present (this is a big difference to pure disk queues!).

    This algorithm prevents unnecessary disk writes, but also leaves some additional buffer space for message bursts. Remember that creating disk files and writing to them is a lengthy operation. It is too lengthy to e.g. block receiving UDP messages. Doing so would result in message loss. Thus, the queue initiates DA mode, but still is able to receive messages and enqueue them - as long as the maximum queue size is not reached. The number of elements between the high water mark and the maximum queue size serves as this "emergency buffer". Size it according to your needs, if traffic is very bursty you will probably need a large buffer here. Keep in mind, though, that under normal operations these queue elements will probably never be used. Setting the high water mark too low will cause disk-assistance to be turned on more often than actually needed.

    The water marks can be set via the "$<object>QueueHighWatermark" and  "$<object>QueueHighWatermark" configuration file directives. Note that these are actual numbers, not precentages. Be sure they make sense (also in respect to "$<object>QueueSize"), as rsyslodg does currently not perform any checks on the numbers provided. It is easy to screw up the system here (yes, a feature enhancement request is filed ;)).

    Limiting the Queue Size

    All queues, including disk queues, have a limit of the number of elements they can enqueue. This is set via the "$<object>QueueSize" config parameter. Note that the size is specified in number of enqueued elements, not their actual memory size. Memory size limits can not be set. A conservative assumption is that a single syslog messages takes up 512 bytes on average (in-memory, NOT on the wire, this *is* a difference).

    Disk assisted queues are special in that they do not have any size limit. The enqueue an unlimited amount of elements. To prevent running out of space, disk and disk-assisted queues can be size-limited via the "$<object>QueueMaxDiskSpace" configuration parameter. If it is not set, the limit is only available free space (and reaching this limit is currently not very gracefully handled, so avoid running into it!). If a limit is set, the queue can not grow larger than it. Note, however, that the limit is approximate. The engine always writes complete records. As such, it is possible that slightly more than the set limit is used (usually less than 1k, given the average message size). Keeping strictly on the limit would be a performance hurt, and thus the design decision was to favour performance. If you don't like that policy, simply specify a slightly lower limit (e.g. 999,999K instead of 1G).

    In general, it is a good idea to limit the pysical disk space even if you dedicate a whole disk to rsyslog. That way, you prevent it from running out of space (future version will have an auto-size-limit logic, that then kicks in in such situations).

    Worker Thread Pools

    Each queue (except in "direct" mode) has an associated pool of worker threads. Worker threads carry out the action to be performed on the data elements enqueued. As an actual sample, the main message queue's worker task is to apply filter logic to each incoming message and enqueue them to the relevant output queues (actions).

    Worker threads are started and stopped on an as-needed basis. On a system without activity, there may be no worker at all running. One is automatically started when a message comes in. Similarily, additional workers are started if the queue grows above a specific size. The "$<object>QueueWorkerThreadMinimumMessages"  config parameter controls worker startup. If it is set to the minimum number of elements that must be enqueued in order to justify a new worker startup. For example, let's assume it is set to 100. As long as no more than 100 messages are in the queue, a single worker will be used. When more than 100 messages arrive, a new worker thread is automatically started. Similarily, a third worker will be started when there are at least 300 messages, a forth when reaching 400 and so on.

    It, however, does not make sense to have too many worker threads running in parall. Thus, the upper limit ca be set via "$<object>QueueWorkerThreads". If it, for example, is set to four, no more than four workers will ever be started, no matter how many elements are enqueued.

    Worker threads that have been started are kept running until an inactivity timeout happens. The timeout can be set via "$<object>QueueWorkerTimeoutThreadShutdown" and is specified in milliseconds. If you do not like to keep the workers running, simply set it to 0, which means immediate timeout and thus immediate shutdown. But consider that creating threads involves some overhead, and this is why we keep them running. If you would like to never shutdown any worker threads, specify -1 for this parameter.

    Discarding Messages

    If the queue reaches the so called "discard watermark" (a number of queued elements), less important messages can automatically be discarded. This is in an effort to save queue space for more important messages, which you even less like to loose. Please note that whenever there are more than "discard watermark" messages, both newly incoming as well as already enqueued low-priority messages are discarded. The algorithm discards messages newly coming in and those at the front of the queue.

    The discard watermark is a last resort setting. It should be set sufficiently high, but low enough to allow for large message burst. Please note that it take effect immediately and thus shows effect promptly - but that doesn't help if the burst mainly consist of high-priority messages...

    The discard watermark is set via the "$<object>QueueDiscardMark" directive. The priority of messages to be discarded is set via "$<object>QueueDiscardSeverity". This directive accepts both the usual textual severity as well as a numerical one. To understand it, you must be aware of the numerical severity values. They are defined in RFC 3164:

            Numerical         Severity
              Code

               0       Emergency: system is unusable
               1       Alert: action must be taken immediately
               2       Critical: critical conditions
               3       Error: error conditions
               4       Warning: warning conditions
               5       Notice: normal but significant condition
               6       Informational: informational messages
               7       Debug: debug-level messages

    Anything of the specified severity and (numerically) above it is discarded. To turn message discarding off, simply specify the discard watermark to be higher than the queue size. An alternative is to specify the numerical value 8 as DiscardSeverity. This is also the default setting to prevent unintentional message loss. So if you would like to use message discarding, you need to set" $<object>QueueDiscardSeverity" to an actual value.

    An interesting application is with disk-assisted queues: if the discard watermark is set lower than the high watermark, message discarding will start before the queue becomes disk-assisted. This may be a good thing if you would like to switch to disk-assisted mode only in cases where it is absolutely unavoidable and you prefer to discard less important messages first.

    Filled-Up Queues

    If the queue has either reached its configured maximum number of entries or disk space, it is finally full. If so, rsyslogd throttles the data element submitter. If that, for example, is a reliable input (TCP, local log socket), that will slow down the message originator which is a good resolution for this scenario.

    During throtteling, a disk-assisted queue continues to write to disk and messages are also discarded based on severity as well as regular dequeuing and processing continues. So chances are good the situation will be resolved by simply throttling. Note, though, that throtteling is highly undesirable for unreliable sources, like UDP message reception. So it is not a good thing to run into throtteling mode at all.

    We can not hold processing infinitely, not even when throtteling. For example, throtteling the local log socket too long would cause the system at whole come to a standstill. To prevent this, rsyslogd times out after a configured period ("$<object>QueueTimeoutEnqueue", specified in milliseconds) if no space becomes available. As a last resort, it then discards the newly arrived message.

    If you do not like throtteling, set the timeout to 0 - the message will then immediately be discarded. If you use a high timeout, be sure you know what you do. If a high main message queue enqueue timeout is set, it can lead to something like a complete hang of the system. The same problem does not apply to action queues.

    Rate Limiting

    Rate limiting provides a way to prevent rsyslogd from processing things too fast. It can, for example, prevent overruning a receiver system.

    Currently, there are only limited rate-limiting features available. The "$<object>QueueDequeueSlowdown"  directive allows to specify how long (in microseconds) dequeueing should be delayed. While simple, it still is powerful. For example, using a DequeueSlowdown delay of 1,000 microseconds on a UDP send action ensures that no more than 1,000 messages can be sent within a second (actually less, as there is also some time needed for the processing itself).

    Processing Timeframes

    Queues can be set to dequeue (process) messages only during certain timeframes. This is useful if you, for example, would like to transfer the bulk of messages only during off-peak hours, e.g. when you have only limited bandwidth on the network path the the central server.

    Currently, only a single timeframe is supported and, even worse, it can only be specified by the hour. It is not hard to extend rsyslog's capabilities in this regard - it was just not requested so far. So if you need more fine-grained control, let us know and we'll probably implement it. There are two configuration directives, both should be used together or results are unpredictable:" $<object>QueueDequeueTimeBegin <hour>" and "$<object>QueueDequeueTimeEnd <hour>". The hour parameter must be specified in 24-hour format (so 10pm is 22). A use case for this parameter can be found in the rsyslog wiki.

    Performance

    The locking involved with maintaining the queue has a potentially large performance impact. How large this is, and if it exists at all, depends much on the configuration and actual use case. However, the queue is able to work on so-called "batches" when dequeueing data elements. With batches, multiple data elements are dequeued at once (with a single locking call). The queue dequeues all available elements up to a configured upper limit (<object>DequeueBatchSize <number>). It is important to note that the actual upper limit is dictated by availability. The queue engine will never wait for a batch to fill. So even if a high upper limit is configured, batches may consist of fewer elements, even just one, if there are no more elements waiting in the queue.

    Batching can improve performance considerably. Note, however, that it affects the order in which messages are passed to the queue worker threads, as each worker now receive as batch of messages. Also, the larger the batch size and the higher the maximum number of permitted worker threads, the more main memory is needed. For a busy server, large batch sizes (around 1,000 or even more elements) may be useful. Please note that with batching, the main memory must hold BatchSize * NumOfWorkers objects in memory (worst-case scenario), even if running in disk-only mode. So if you use the default 5 workers at the main message queue and set the batch size to 1,000, you need to be prepared that the main message queue holds up to 5,000 messages in main memory in addition to the configured queue size limits!

    The queue object's default maximum batch size is eight, but there exists different defaults for the actual parts of rsyslog processing that utilize queues. So you need to check these object's defaults.

    Terminating Queues

    Terminating a process sounds easy, but can be complex. Terminating a running queue is in fact the most complex operation a queue object can perform. You don't see that from a user's point of view, but its quite hard work for the developer to do everything in the right order.

    The complexity arises when the queue has still data enqueued when it finishes. Rsyslog tries to preserve as much of it as possible. As a first measure, there is a regular queue time out ("$<object>QueueTimeoutShutdown", specified in milliseconds): the queue workers are given that time period to finish processing the queue.

    If after that period there is still data in the queue, workers are instructed to finish the current data element and then terminate. This essentially means any other data is lost. There is another timeout ("$<object>QueueTimeoutActionCompletion", also specified in milliseconds) that specifies how long the workers have to finish the current element. If that timeout expires, any remaining workers are cancelled and the queue is brought down.

    If you do not like to lose data on shutdown, the "$<object>QueueSaveOnShutdown" parameter can be set to "on". This requires either a disk or disk-assisted queue. If set, rsyslogd ensures that any queue elements are saved to disk before it terminates. This includes data elements there were begun being processed by workers that needed to be cancelled due to too-long processing. For a large queue, this operation may be lengthy. No timeout applies to a required shutdown save.

    Error Messages

    This page covers error message you may see when setting up rsyslog with TLS. Please note that many of the message stem back to the TLS library being used. In those cases, there is not always a good explanation available in rsyslog alone.

    A single error typically results in two or more message being emitted: (at least) one is the actual error cause, followed by usually one message with additional information (like certificate contents). In a typical system, these message should immediately follow each other in your log. Kepp in mind that they are reported as syslog.err, so you need to capture these to actually see errors (the default rsyslog.conf's shipped by many systems will do that, recording them e.g. in /etc/messages).

    certificate invalid

    Sample: not permitted to talk to peer, certificate invalid: insecure algorithm

    This message may occur during connection setup. It indicates that the remote peer's certificate can not be accepted. The reason for this is given in the message part that is shown in red. Please note that this red part directly stems back to the TLS library, so rsyslog does acutally not have any more information about the reason.

    With GnuTLS, the following reasons have been seen in practice:

    insecure algorith

    The certificate contains information on which encryption algorithms are to be used. This information is entered when the certificate is created. Some older alogrithms are no longer secure and the TLS library does not accept them. Thus the connection request failed. The cure is to use a certificate with sufficiently secure alogorithms.

    Please note that noi encryption algorithm is totally secure. It only is secure based on our current knowledge AND on computing power available. As computers get more and more powerful, previously secure algorithms become insecure over time. As such, algorithms considered secure today may not be accepted by the TLS library in the future.

    So in theory, after a system upgrade, a connection request may fail with the "insecure algorithm" failure without any change in rsyslog configuration or certificates. This could be caused by a new perception of the TLS library of what is secure and what not.

    GnuTLS error -64

    Sample: unexpected GnuTLS error -64 in nsd_gtls.c:517: Error while reading file.

    This error points to an encoding error witht the pem file in question. It means "base 64 encoding error". From my experience, it can be caused by a couple of things, some of them not obvious:

    • You specified a wrong file, which is not actually in .pem format
    • The file was incorrectly generated
    • I think I have also seen this when I accidently swapped private key files and certificate files. So double-check the type of file you are using.
    • It may even be a result of an access (permission) problem. In theory, that should lead to another error, but in practice it sometimes seems to lead to this -64 error.

    info on invalid cert

    Sample: info on invalid cert: peer provided 1 certificate(s). Certificate 1 info: certificate valid from Wed Jun 18 11:45:44 2008 to Sat Jun 16 11:45:53 2018; Certificate public key: RSA; DN: C=US,O=Sample Corp,OU=Certs,L=Somehwere,ST=CA,CN=somename; Issuer DN: C=US,O=Sample Corp,OU=Certs,L=Somewhere,ST=CA,CN=somename,EMAIL=xxx@example.com; SAN:DNSname: machine.example.net;

    This is not an error message in itself. It always follows the actual error message and tells you what is seen in the peer's certificate. This is done to give you a chance to evaluate the certificate and better understand why the initial error message was issued.

    Please note that you can NOT diagnose problems based on this message alone. It follows in a number of error cases and does not pinpoint any problems by itself.

    mmsnmptrapd message modification module

    Module Name:    imtcp

    Author: Rainer Gerhards <rgerhards@adiscon.com> (custom-created)

    Multi-Ruleset Support: since 5.8.1

    Description:

    This module uses a specific configuration of snmptrapd's tag values to obtain information of the original source system and the severity present inside the original SNMP trap. It then replaces these fields inside the syslog message.

    Let's look at an example. Essentially, SNMPTT will invoke something like this: 

    logger -t snmptrapd/warning/realhost Host 003c.abcd.ffff in vlan 17 is flapping between port Gi4/1 and port Gi3/2

    This message modification module will change the tag (removing the additional information), hostname and severity (not shown in example), so the log entry will look as follows: 

    2011-04-21T16:43:09.101633+02:00 realhost snmptrapd: Host 003c.abcd.ffff in vlan 122 is flapping between port Gi4/1 and port Gi3/2
    The following logic is applied to all message being processed:
    1. The module checks incoming syslog entries. If their TAG field starts with "snmptrapd/" (configurable), they are modified, otherwise not. If the are modified, this happens as follows:
    2. It will derive the hostname from the tag field which has format snmptrapd/severity/hostname
    3. It should derive the severity from the tag field which has format snmptrapd/severity/hostname. A configurable mapping table will be used to drive a new severity value from that severity string. If no mapping has been defined, the original severity is not changed.
    4. It replaces the "FromHost" value with the derived value from step2
    5. It replaces the "Severity" value with the derived value from step 3

    Note that the placement of this module inside the configuration is important. All actions before this modules is called will work on the unmodified message. All messages after it's call will work on the modified message. Please also note that there is some extra power in case it is required: as this module is implemented via the output module interface, a filter can be used (actually must be used) in order to tell when it is called. Usually, the catch-all filter (*.*) is used, but more specific filters are fully supported. So it is possible to define different parameters for this module depending on different filters. It is also possible to just run messages from one remote system through this module, with the help of filters or multiple rulesets and ruleset bindings. In short words, all capabilities rsyslog offers to control output modules are also available to mmsnmptrapd.

    Configuration Directives:

    • $mmsnmptrapdTag [tagname]
      tells the module which start string inside the tag to look for. The default is "snmptrapd". Note that a slash is automatically added to this tag when it comes to matching incoming messages. It MUST not be given, except if two slashes are required for whatever reasons (so "tag/" results in a check for "tag//" at the start of the tag field).
    • $mmsnmptrapdSeverityMapping [severtiymap]
      This specifies the severity mapping table. It needs to be specified as a list. Note that due to the current config system no whitespace is supported inside the list, so be sure not to use any whitespace inside it.
      The list is constructed of Severtiy-Name/Severity-Value pairs, delimited by comma. Severity-Name is a case-sensitive string, e.g. "warning" and an associated numerical value (e.g. 4). Possible values are in the rage 0..7 and are defined in RFC5424, table 2. The given sample would be specified as "warning/4".
      If multiple instances of mmsnmptrapd are used, each instance uses the most recently defined $mmsnmptrapdSeverityMapping before itself.
    Caveats/Known Bugs:
    • currently none known

    Example:

    This enables to rewrite messages from snmptrapd and configures error and warning severities. The default tag is used.

    How you can Help

    You like rsyslog and would like to lend us a helping hand? This page tells you how easy it is to help a little bit. You can contribute to the project even with a single mouse click! If you could pick a single item from the wish list, that would be awfully helpful!

    This is our wish list:

    • let others know how great rsyslog is
    • let us know about rsyslog - we are eager for feedback
      • tell us what you like and what you not like - so that we can include that into development
      • tell us what you use rsyslog for - especially if you have high traffic volume or an otherwise "uncommon" deployment. We are looking for case studies and experience how rsyslog performs in unusual scenarios.
      • allow us to post your thoughts and experiences as a "user story" on the web site (so far, none are there ;))
    • if you know how to create packages (rpm, deb, ...)
      • we would very much appreciate your help with package creation. We know that it is important to have good binary packages for a product to spread widely. Yet, we do not have the knowledge to do it all ourselves. Drop Rainer a note if you could help us out.
    • if you have configured a device for sending syslog data, and that device is not in our syslog configuration database, you might want to tell us how to configure it.
    • if you are a corporate user

    We appreciate your help very much. A big thank you for anything you might do!

    Log Message Normalization Module

    Module Name:    mmnormalize

    Available since: 6.1.2+

    Author: Rainer Gerhards <rgerhards@adiscon.com>

    Description:

    This module provides the capability to normalize log messages via liblognorm. Thanks to liblognorm, unstructured text, like usually found in log messages, can very quickly be parsed and put into a normal form. This is done so quickly, that it should be possible to normalize events in realtime.

    This module is implemented via the output module interface. This means that mmnormalize should be called just like an action. After it has been called, the normalized message properties are avaialable and can be accessed. These properties are called the "CEE/lumberjack" properties, because liblognorm creates a format that is inspired by the CEE/lumberjack approach.

    Please note: CEE/lumberjack properties are different from regular properties. They have always "$!" prepended to the property name given in the rulebase. Such a property needs to be called with %$!propertyname%.

    Note that mmnormalize should only be called once on each message. Behaviour is undefined if multiple calls to mmnormalize happen for the same message.

    Action Parameters:

    • ruleBase [word]
      Specifies which rulebase file is to use. If there are multiple mmnormalize instances, each one can use a different file. However, a single instance can use only a single file. This parameter MUST be given, because normalization can only happen based on a rulebase. It is recommended that an absolute path name is given. Information on how to create the rulebase can be found in the liblognorm manual.
    • useRawMsg [boolean]
      Specifies if the raw message should be used for normalization (on) or just the MSG part of the message (off). Default is "off".

    Legacy Configuration Directives:

    • $mmnormalizeRuleBase <rulebase-file> - equivalent to the "ruleBase" parameter.
    • $mmnormalizeUseRawMsg <on/off> - equivalent to the "useRawMsg" parameter.
    Caveats/Known Bugs:

    None known at this time.

Sample:

This activates the module and applies normalization to all messages:

This is a part of the rsyslog.conf documentation.

Filter Conditions

Rsyslog offers three different types "filter conditions":

  • RainerScript-based filters
  • "traditional" severity and facility based selectors
  • property-based filters

RainerScript-Based Filters

RainerScript based filters are the prime means of creating complex rsyslog configuration. The permit filtering on arbitrary complex expressions, which can include boolean, arithmetic and string operations. They also support full nesting of filters, just as you know from other scripting environments.
Scripts based filters are indicated by the keyword "if", as usual. They have this format:

if expr then block else block
"If" and "then" are fixed keywords that mus be present. "expr" is a (potentially quite complex) expression. So the expression documentation for details. The keyword "else" and its associated block is optional. Note that a block can contain either a single action (chain), or an arbitrary complex script enclosed in curly braces, e.g.: 
if $programname == 'prog1' then {
   action(type="omfile" file="/var/log/prog1.log")
   if $msg contains 'test' then
     action(type="omfile" file="/var/log/prog1test.log")
   else
     action(type="omfile" file="/var/log/prog1notest.log")
}

Other types of filtes can also be combined with the pure RainerScript ones. This makes it particularly easy to migrate from early config files to RainerScript. Also, the traditional syslog PRI-based filters are a good and easy to use addition. While they are legacy, we still recommend there use where they are up to the job. We do NOT, however, recommend property-based filters any longer. As an example, the following is perfectly valid: 
if $fromhost == 'host1' then {
   mail.* action(type="omfile" file="/var/log/host1/mail.log")
   *.err /var/log/host1/errlog # this is also still valid
   # 
   # more "old-style rules" ...
   #
} else {
   mail.* action(type="omfile" file="/var/log/mail.log")
   *.err /var/log/errlog
   # 
   # more "old-style rules" ...
   #
}

Right now, you need to specify numerical values if you would like to check for facilities and severity. These can be found in RFC 3164. If you don't like that, you can of course also use the textual property - just be sure to use the right one. As expression support is enhanced, this will change. For example, if you would like to filter on message that have facility local0, start with "DEVNAME" and have either "error1" or "error0" in their message content, you could use the following filter:

if $syslogfacility-text == 'local0' and $msg startswith 'DEVNAME' and ($msg contains 'error1' or $msg contains 'error0') then /var/log/somelog
Please note that the above must all be on one line! And if you would like to store all messages except those that contain "error1" or "error0", you just need to add a "not":

if $syslogfacility-text == 'local0' and $msg startswith 'DEVNAME' and not ($msg contains 'error1' or $msg contains 'error0') then /var/log/somelog
If you would like to do case-insensitive comparisons, use "contains_i" instead of "contains" and "startswith_i" instead of "startswith".

Regular expressions are supported via functions (see function list).

Selectors

Selectors are the traditional way of filtering syslog messages. They have been kept in rsyslog with their original syntax, because it is well-known, highly effective and also needed for compatibility with stock syslogd configuration files. If you just need to filter based on priority and facility, you should do this with selector lines. They are not second-class citizens in rsyslog and offer the best performance for this job.

The selector field itself again consists of two parts, a facility and a priority, separated by a period (".''). Both parts are case insensitive and can also be specified as decimal numbers, but don't do that, you have been warned. Both facilities and priorities are described in syslog(3). The names mentioned below correspond to the similar LOG_-values in /usr/include/syslog.h.

The facility is one of the following keywords: auth, authpriv, cron, daemon, kern, lpr, mail, mark, news, security (same as auth), syslog, user, uucp and local0 through local7. The keyword security should not be used anymore and mark is only for internal use and therefore should not be used in applications. Anyway, you may want to specify and redirect these messages here. The facility specifies the subsystem that produced the message, i.e. all mail programs log with the mail facility (LOG_MAIL) if they log using syslog.

The priority is one of the following keywords, in ascending order: debug, info, notice, warning, warn (same as warning), err, error (same as err), crit, alert, emerg, panic (same as emerg). The keywords error, warn and panic are deprecated and should not be used anymore. The priority defines the severity of the message.

The behavior of the original BSD syslogd is that all messages of the specified priority and higher are logged according to the given action. Rsyslogd behaves the same, but has some extensions.

In addition to the above mentioned names the rsyslogd(8) understands the following extensions: An asterisk ("*'') stands for all facilities or all priorities, depending on where it is used (before or after the period). The keyword none stands for no priority of the given facility.

You can specify multiple facilities with the same priority pattern in one statement using the comma (",'') operator. You may specify as much facilities as you want. Remember that only the facility part from such a statement is taken, a priority part would be skipped.

Multiple selectors may be specified for a single action using the semicolon (";'') separator. Remember that each selector in the selector field is capable to overwrite the preceding ones. Using this behavior you can exclude some priorities from the pattern.

Rsyslogd has a syntax extension to the original BSD source, that makes its use more intuitively. You may precede every priority with an equals sign ("='') to specify only this single priority and not any of the above. You may also (both is valid, too) precede the priority with an exclamation mark ("!'') to ignore all that priorities, either exact this one or this and any higher priority. If you use both extensions than the exclamation mark must occur before the equals sign, just use it intuitively.

Property-Based Filters

Property-based filters are unique to rsyslogd. They allow to filter on any property, like HOSTNAME, syslogtag and msg. A list of all currently-supported properties can be found in the property replacer documentation (but keep in mind that only the properties, not the replacer is supported). With this filter, each properties can be checked against a specified value, using a specified compare operation.

A property-based filter must start with a colon in column 0. This tells rsyslogd that it is the new filter type. The colon must be followed by the property name, a comma, the name of the compare operation to carry out, another comma and then the value to compare against. This value must be quoted. There can be spaces and tabs between the commas. Property names and compare operations are case-sensitive, so "msg" works, while "MSG" is an invalid property name. In brief, the syntax is as follows:

:property, [!]compare-operation, "value"

The following compare-operations are currently supported:

contains Checks if the string provided in value is contained in the property. There must be an exact match, wildcards are not supported.
isempty Checks if the property is empty. The value is discarded. This is especially useful when working with normalized data, where some fields may be populated based on normalization result. Available since 6.6.2.
isequal Compares the "value" string provided and the property contents. These two values must be exactly equal to match. The difference to contains is that contains searches for the value anywhere inside the property value, whereas all characters must be identical for isequal. As such, isequal is most useful for fields like syslogtag or FROMHOST, where you probably know the exact contents.
startswith Checks if the value is found exactly at the beginning of the property value. For example, if you search for "val" with

:msg, startswith, "val"

it will be a match if msg contains "values are in this message" but it won't match if the msg contains "There are values in this message" (in the later case, contains would match). Please note that "startswith" is by far faster than regular expressions. So it makes very much sense (performance-wise) to use "startswith".

Note: when processing syslog messages, please note that $msg usually starts with a space. The reason for this is RFC3164. Please read the detail description of what that means to you. In short, you need to make sure that you include the first space if you use "startswith", otherwise you will not get matches.

regex Compares the property against the provided POSIX BRE regular expression.
ereregex Compares the property against the provided POSIX ERE regular expression.

You can use the bang-character (!) immediately in front of a compare-operation, the outcome of this operation is negated. For example, if msg contains "This is an informative message", the following sample would not match:

:msg, contains, "error"

but this one matches:

:msg, !contains, "error"

Using negation can be useful if you would like to do some generic processing but exclude some specific events. You can use the discard action in conjunction with that. A sample would be:

*.* /var/log/allmsgs-including-informational.log
:msg, contains, "informational"  ~
*.* /var/log/allmsgs-but-informational.log

Do not overlook the red tilde in line 2! In this sample, all messages are written to the file allmsgs-including-informational.log. Then, all messages containing the string "informational" are discarded. That means the config file lines below the "discard line" (number 2 in our sample) will not be applied to this message. Then, all remaining lines will also be written to the file allmsgs-but-informational.log.

Value is a quoted string. It supports some escape sequences:

\" - the quote character (e.g. "String with \"Quotes\"")
\\ - the backslash character (e.g. "C:\\tmp")

Escape sequences always start with a backslash. Additional escape sequences might be added in the future. Backslash characters must be escaped. Any other sequence then those outlined above is invalid and may lead to unpredictable results.

Probably, "msg" is the most prominent use case of property based filters. It is the actual message text. If you would like to filter based on some message content (e.g. the presence of a specific code), this can be done easily by:

:msg, contains, "ID-4711"

This filter will match when the message contains the string "ID-4711". Please note that the comparison is case-sensitive, so it would not match if "id-4711" would be contained in the message.

:msg, regex, "fatal .* error"

This filter uses a POSIX regular expression. It matches when the string contains the words "fatal" and "error" with anything in between (e.g. "fatal net error" and "fatal lib error" but not "fatal error" as two spaces are required by the regular expression!).

Getting property-based filters right can sometimes be challenging. In order to help you do it with as minimal effort as possible, rsyslogd spits out debug information for all property-based filters during their evaluation. To enable this, run rsyslogd in foreground and specify the "-d" option.

Boolean operations inside property based filters (like 'message contains "ID17" or message contains "ID18"') are currently not supported (except for "not" as outlined above). Please note that while it is possible to query facility and severity via property-based filters, it is far more advisable to use classic selectors (see above) for those cases.

IP Address Anonimization Module (mmanon)

Module Name:    mmanon

Author: Rainer Gerhards <rgerhards@adiscon.com>

Available since: 7.3.7

Description:

The mmanon module permits to anonymize IP addresses. It is a message modification module that actually changes the IP address inside the message, so after calling mmanon, the original message can no longer be obtained. Note that anonymization will break digital signatures on the message, if they exist.

How are IP-Addresses defined?

We assume that an IP address consists of four octets in dotted notation, where each of the octets has a value between 0 and 255, inclusively. After the last octet, there must be either a space or a colon. So, for example, "1.2.3.4 Test" and "1.2.3.4:514 Test" are detected as containing valid IP addresses, whereas this is not the case for "1.2.300.4 Test" or "1.2.3.4-Test". The message text may contain multiple addresses. If so, each of them is anonimized (according to the same rules). Important: We may change the set of acceptable characters after the last octet in the future, if there are good reasons to do so.

 

Module Configuration Parameters:

Currently none.

 

Action Confguration Parameters:

  • mode - default "rewrite"
    There exists the "simple" and "rewrite" mode. In simple mode, only octets as whole can be anonymized and the length of the message is never changed. This means that when the last three octets of the address 10.1.12.123 are anonymized, the result will be 10.0.00.000. This means that the length of the original octets is still visible and may be used to draw some privacy-evasive conclusions. This mode is slightly faster than "overwrite" mode, and this may matter in high throughput environments.
    The default "rewrite" mode will do full anonymization of any number of bits and it will also normlize the address, so that no information about the original IP address is available. So in the above example, 10.1.12.123 would be anonymized to 10.0.0.0.
  • ipv4.bits - default 16
    This set the number of bits that should be anonymized (bits are from the right, so lower bits are anonymized first). This setting permits to save network information while still anonymizing user-specific data. The more bits you discard, the better the anonymization obviously is. The default of 16 bits reflects what German data privacy rules consider as being sufficinetly anonymized. We assume, this can also be used as a rough but conservative guideline for other countries.
    Note: when in simple mode, only bits on a byte boundary can be specified. As such, any value other than 8, 16, 24 or 32 is invalid. If an invalid value is given, it is rounded to the next byte boundary (so we favor stronger anonymization in that case). For example, a bit value of 12 will become 16 in simple mode (an error message is also emitted).
  • replacementChar - default "x"
    In simple mode, this sets the character that the to-be-anonymized part of the IP address is to be overwritten with. In rewrite mode, this parameter is not permitted, as in this case we need not necessarily rewrite full octets. As such, the anonymized part is always zero-filled and replacementChar is of no use. If it is specified, an error message is emitted and the parameter ignored.

Caveats/Known Bugs:

  • only IPv4 is supported

Samples:

In this snippet, we write one file without anonymization and another one with the message anonymized. Note that once mmanon has run, access to the original message is no longer possible (execept if stored in user variables before anonymization).

This next snippet is almost identical to the first one, but here we anonymize the full IPv4 address. Note that by modifying the number of bits, you can anonymize different parts of the address. Keep in mind that in simple mode (used here), the bit values must match IP address bytes, so for IPv4 only the values 8, 16, 24 and 32 are valid. Also, in this example the replacement is done via asterisks instead of lower-case "x"-letters. Also keep in mind that "replacementChar" can only be set in simple mode.

The next snippet is also based on the first one, but anonimzes an "odd" number of bits, 12. The value of 12 is used by some folks as a compromise between keeping privacy and still permiting to gain some more in-depth insight from log files. Note that anonymizing 12 bits may be insufficient to fulfill legal requirements (if such exist).

Lookup Tables

NOTE: this is proposed functionality, which is NOT YET IMPLEMENTED!

Lookup tables are a powerful construct to obtain "class" information based on message content (e.g. to build log file names for different server types, departments or remote offices).

The base idea is to use a message variable as an index into a table which then returns another value. For example, $fromhost-ip could be used as an index, with the table value representing the type of server or the department or remote office it is located in. A main point with lookup tables is that the lookup is very fast. So while lookup tables can be emulated with if-elseif constructs, they are generally much faster. Also, it is possible to reload lookup tables during rsyslog runtime without the need for a full restart.

The lookup tables itself exists in a separate configuration file (one per table). This file is loaded on rsyslog startup and when a reload is requested.

There are different types of lookup tables:

  • string - the value to be looked up is an arbitrary string. Only exact some strings match.
  • array - the value to be looked up is an integer number from a consequtive set. The set does not need to start at zero or one, but there must be no number missing. So, for example 5,6,7,8,9 would be a valid set of index values, while 1,2,4,5 would not be (due to missing 2). A match happens if the requested number is present.
  • sparseArray - the value to be looked up is an integer value, but there may be gaps inside the set of values (usually there are large gaps). A typical use case would be the matching of IPv4 address information. A match happens on the first value that is less than or equal to the requested value.

Note that index integer numbers are represented by unsigned 32 bits.

Lookup tables can be access via the lookup() built-in function. The core idea is to set a local variable to the lookup result and later on use that local variable in templates.

More details on usage now follow.

Lookup Table File Format

Lookup table files contain a single JSON object. This object contains of a header and a table part.

Header

The header is the top-level json. It has paramters "version", "nomatch", and "type". The version parameter must be given and must always be one for this version of rsyslog. The nomatch parameter is optional. If specified, it contains the value to be used if lookup() is provided an index value for which no entry exists. The default for "nomatch" is the empty string. Type specifies the type of lookup to be done.

Table

This must be an array of elements, even if only a single value exists (for obvious reasons, we do not expect this to occur often). Each array element must contain two fields "index" and "value".

Example

This is a sample of how an ip-to-office mapping may look like: 

{ "version":1, "nomatch":"unk", "type":"string",
  "table":[ {"index":"10.0.1.1", "value":"A" },
          {"index":"10.0.1.2", "value":"A" },
          {"index":"10.0.1.3", "value":"A" },
          {"index":"10.0.2.1", "value":"B" },
          {"index":"10.0.2.2", "value":"B" },
          {"index":"10.0.2.3", "value":"B" }
        ]
}
Note: if a different IP comes in, the value "unk" is returend thanks to the nomatch parameter in the first line.

RainerScript Statements

lookup_table() Object

This statement defines and intially loads a lookup table. Its format is as follows: 

lookup_table(name="name" file="/path/to/file" reloadOnHUP="on|off")

Parameters

  • name (mandatory)
    Defines the name of lookup table for further reference inside the configuration. Names must be unique. Note that it is possible, though not advisible, to have different names for the same file.
  • file (mandatory)
    Specifies the full path for the lookup table file. This file must be readable for the user rsyslog is run under (important when dropping privileges). It must point to a valid lookup table file as described above.
  • reloadOnHUP (optional, default "on")
    Specifies if the table shall automatically be reloaded as part of HUP processing. For static tables, the default is "off" and specifying "on" triggers an error message. Note that the default of "on" may be somewhat suboptimal performance-wise, but probably is what the user intuitively expects. Turn it off if you know that you do not need the automatic reload capability.

lookup() Function

This function is used to actually do the table lookup. Format: 

lookup_table("name", indexvalue)

Parameters

  • return value
    The function returns the string that is associated with the given indexvalue. If the indexvalue is not present inside the lookup table, the "nomatch" string is returned (or an empty string if it is not defined).
  • name (constant string)
    The lookup table to be used. Note that this must be specificed as a constant. In theory, variable table names could be made possible, but their runtime behaviour is not as good as for static names, and we do not (yet) see good use cases where dynamic table names could be useful.
  • indexvalue (expression)
    The value to be looked up. While this is an arbitrary RainerScript expression, it's final value is always converted to a string in order to conduct the lookup. For example, "lookup(table, 3+4)" would be exactly the same as "lookup(table, "7")". In most cases, indexvalue will probably be a single variable, but it could also be the result of all RainerScript-supported expression types (like string concatenation or substring extraction). Valid samples are "lookup(name, $fromhost-ip & $hostname)" or "lookup(name, substr($fromhost-ip, 0, 5))" as well as of course the usual "lookup(table, $fromhost-ip)".

load_lookup_table Statement

Note: in the final implementation, this MAY be implemented as an action. This is a low-level decesion that must be made during the detail development process. Parameters and semantics will remain the same of this happens.

This statement is used to reload a lookup table. It will fail if the table is static. While this statement is executed, lookups to this table are temporarily blocked. So for large tables, there may be a slight performance hit during the load phase. It is assume that always a triggering condition is used to load the table. 

load_lookup_table(name="name" errOnFail="on|off" valueOnFail="value")

Parameters

  • name (string)
    The lookup table to be used.
  • errOnFail (boolean, default "on")
    Specifies whether or not an error message is to be emitted if there are any problems reloading the lookup table.
  • valueOnFail (optional, string)
    This parameter affects processing if the lookup table cannot be loaded for some reason: If the parameter is not present, the previous table will be kept in use. If the parameter is given, the previous table will no longer be used, and instead an empty table be with nomath=valueOnFail be generated. In short, that means when the parameter is set and the reload fails, all matches will always return what is specified in valueOnFail.

Usage example

For clarity, we show only those parts of rsyslog.conf that affect lookup tables. We use the remote office example that an example lookup table file is given above for. 

lookup_table(name="ip2office" file="/path/to/ipoffice.lu"
             reloadOnHUP="off")


template(name="depfile" type="string"
         string="/var/log/%$usr.dep%/messages")

set $usr.dep = lookup("ip2office", $fromhost-ip);
action(type="omfile" dynfile="depfile")

# support for reload "commands"
if $fromhost-ip == "10.0.1.123"
   and $msg contains "reload office lookup table"
   then
   load_lookup_table(name="ip2office" errOnFail="on")

Note: for performance reasons, it makes sense to put the reload command into a dedicated ruleset, bound to a specific listener - which than should also be sufficiently secured, e.g. via TLS mutual auth.

Implementation Details

The lookup table functionality is implemented via highly efficient algorithms. The string lookup is based on a parse tree and has O(1) time complexity. The array lookup is also O(1). In case of sparseArray, we have O(log n).

To preserve space and, more important, increase cache hit performance, equal data values are only stored once, no matter how often a lookup index points to them.

troubleshooting rsyslog

Having trouble with rsyslog? This page provides some tips on where to look for help and what to do if you need to ask for assistance. This page is continously being expanded.

Useful troubleshooting ressources are:

  • The rsyslog documentation - note that the online version always covers the most recent development version. However, there is a version-specific doc set in each tarball. If you installed rsyslog from a package, there usually is a rsyslog-doc package, that often needs to be installed separately.
  • The rsyslog wiki provides user tips and experiences.
  • Check the bugzilla to see if your problem is a known (and even fixed ;)) bug.

Malformed Messages and Message Properties

A common trouble source are ill-formed syslog messages, which lead to to all sorts of interesting problems, including malformed hostnames and dates. Read the quoted guide to find relief. A common symptom is that the %HOSTNAME% property is used for generating dynafile names, but some glibberish shows up. This is caused by the malformed syslog messages, so be sure to read the guide if you face that problem. Just let me add that the common work-around is to use %FROMHOST% or %FROMHOST-IP% instead. These do not take the hostname from the message, but rather use the host that sent the message (taken from the socket layer). Of course, this does not work over NAT or relay chains, where the only cure is to make sure senders emit well-formed messages.

Configuration Problems

Rsyslog 3.21.1 and above has been enhanced to support extended configuration checking. It offers a special command line switch (-N1) that puts it into "config verfication mode". In that mode, it interprets and check the configuration file, but does not startup. This mode can be used in parallel to a running instance of rsyslogd.

To enable it, run rsyslog interactively as follows:

/path/to/rsyslogd -f/path/to/config-file -N1

You should also specify other options you usually give (like -c3 and whatever else). Any problems experienced are reported to stderr [aka "your screen" (if not redirected)].

Configuration Graphs

Starting with rsyslog 4.3.1, the "$GenerateConfigGraph" command is supported, a very valuable troubleshooting tool. It permits to generate a graph of how rsyslogd understood its configuration file. It is assumed that many configuration issues can easily be detected just by looking at the configuration graph. Full details of how to generate the graphs, and what to look for can be found in the "$GenerateConfigGraph" manual page.

Asking for Help

If you can't find the answer yourself, you should look at these places for community help.

  • The rsyslog forum. This is the preferred method of obtaining support.
  • The rsyslog mailing list. This is a low-volume list which occasional gets traffic spikes. The mailing list is probably a good place for complex questions.

Debug Log

If you ask for help, there are chances that we need to ask for an rsyslog debug log. The debug log is a detailled report of what rsyslog does during processing. As such, it may even be useful for your very own troubleshooting. People have seen things inside their debug log that enabled them to find problems they did not see before. So having a look at the debug log, even before asking for help, may be useful.

Note that the debug log contains most of those things we consider useful. This is a lot of information, but may still be too few. So it sometimes may happen that you will be asked to run a specific version which has additional debug output. Also, we revise from time to time what is worth putting into the standard debug log. As such, log content may change from version to version. We do not guarantee any specific debug log contents, so do not rely on that. The amount of debug logging can also be controlled via some environment options. Please see debugging support for further details.

In general, it is advisable to run rsyslogd in the foreground to obtain the log. To do so, make sure you know which options are usually used when you start rsyslogd as a background daemon. Let's assume "-c3" is the only option used. Then, do the following:

  • make sure rsyslogd as a daemon is stopped (verify with ps -ef|grep rsyslogd)
  • make sure you have a console session with root permissions
  • run rsyslogd interactively: /sbin/rsyslogd ..your options.. -dn > logfile
    where "your options" is what you usually use. /sbin/rsyslogd is the full path to the rsyslogd binary (location different depending on distro). In our case, the command would be
    /sbin/rsyslogd -c3 -dn > logfile
  • press ctrl-C when you have sufficient data (e.g. a device logged a record)
    NOTE: rsyslogd will NOT stop automatically - you need to ctrl-c out of it!
  • Once you have done all that, you can review logfile. It contains the debug output.
  • When you are done, make sure you re-enable (and start) the background daemon!

If you need to submit the logfile, you may want to check if it contains any passwords or other sensitive data. If it does, you can change it to some consistent meaningless value. Do not delete the lines, as this renders the debug log unusable (and makes Rainer quite angry for wasted time, aka significantly reduces the chance he will remain motivated to look at your problem ;)). For the same reason, make sure whatever you change is change consistently. Really!

Debug log file can get quite large. Before submitting them, it is a good idea to zip them. Rainer has handled files of around 1 to 2 GB. If your's is larger ask before submitting. Often, it is sufficient to submit the first 2,000 lines of the log file and around another 1,000 around the area where you see a problem. Also, ask you can submit a file via private mail. Private mail is usually a good way to go for large files or files with sensitive content. However, do NOT send anything sensitive that you do not want the outside to be known. While Rainer so far made effort no to leak any sensitive information, there is no guarantee that doesn't happen. If you need a guarantee, you are probably a candidate for a commercial support contract. Free support comes without any guarantees, include no guarantee on confidentiality [aka "we don't want to be sued for work were are not even paid for ;)]. So if you submit debug logs, do so at your sole risk. By submitting them, you accept this policy.

Segmentation Faults

Rsyslog has a very rapid development process, complex capabilities and now gradually gets more and more exposure. While we are happy about this, it also has some bad effects: some deployment scenarios have probably never been tested and it may be impossible to test them for the development team because of resources needed. So while we try to avoid this, you may see a serious problem during deployments in demanding, non-standard, environments (hopefully not with a stable version, but chances are good you'll run into troubles with the development versions).

Active support from the user base is very important to help us track down those things. Most often, serious problems are the result of some memory misadressing. During development, we routinely use valgrind, a very well and capable memory debugger. This helps us to create pretty clean code. But valgrind can not detect everything, most importantly not code pathes that are never executed. So of most use for us is information about aborts and abort locations.

Unforutnately, faults rooted in adressing errors typically show up only later, so the actual abort location is in an unrelated spot. To help track down the original spot, libc later than 5.4.23 offers support for finding, and possible temporary relief from it, by means of the MALLOC_CHECK_ environment variable. Setting it to 2 is a useful troubleshooting aid for us. It will make the program abort as soon as the check routines detect anything suspicious (unfortunately, this may still not be the root cause, but hopefully closer to it). Setting it to 0 may even make some problems disappear (but it will NOT fix them!). With functionality comes cost, and so exporting MALLOC_CHECK_ without need comes at a performance penalty. However, we strongly recommend adding this instrumentation to your test environment should you see any serious problems. Chances are good it will help us interpret a dump better, and thus be able to quicker craft a fix.

In order to get useful information, we need some backtrace of the abort. First, you need to make sure that a core file is created. Under Fedora, for example, that means you need to have an "ulimit -c unlimited" in place.

Now let's assume you got a core file (e.g. in /core.1234). So what to do next? Sending a core file to us is most often pointless - we need to have the exact same system configuration in order to interpret it correctly. Obviously, chances are extremely slim for this to be. So we would appreciate if you could extract the most important information. This is done as follows:

  • $gdb /path/to/rsyslogd
  • $info thread
  • you'll see a number of threads (in the range 0 to n with n being the highest number). For each of them, do the following (let's assume that i is the thread number):
    • $ thread i (e.g. thread 0, thread 1, ...)
    • $bt
  • then you can quit gdb with "$q"

Then please send all information that gdb spit out to the development team. It is best to first ask on the forum or mailing list on how to do that. The developers will keep in contact with you and, I fear, will probably ask for other things as well ;)

Note that we strive for highest reliability of the engine even in unusual deployment scenarios. Unfortunately, this is hard to achieve, especially with limited resources. So we are depending on cooperation from users. This is your chance to make a big contribution to the project without the need to program or do anything else except get a problem solved ;)

Pipe Output Module

Module Name:    omfwd

Author: Rainer Gerhards <rgergards@adiscon.com>

Description:

The ompipe plug-in provides the core functionality for logging output to named pipes (fifos). It is a built-in module that does not need to be loaded.

 

Global Configuration Directives:

  • Template [templateName]
    sets a new default template for file actions.

 

Action specific Configuration Directives:

  • Pipe string
    A fifo or named pipe can be used as a destination for log messages.

Caveats/Known Bugs:

  • None.

Sample:

The following command sends all syslog messages to a remote server via TCP port 10514.



Legacy Configuration Directives:

rsyslog has support for logging output to named pipes (fifos). A fifo or named pipe can be used as a destination for log messages by prepending a pipe symbol ("|'') to the name of the file. This is handy for debugging. Note that the fifo must be created with the mkfifo(1) command before rsyslogd is started.

Legacy Sample:

The following command sends all syslog messages to a remote server via TCP port 10514.

Encrypting Syslog Traffic with TLS (SSL)

Written by Rainer Gerhards (2008-07-03)

Setting up the UDP syslog relay

In this step, we configure the UDP relay ada.example.net. As a reminder, that machine relays messages from a local router, which only supports UDP syslog, to the central syslog server. The router does not talk directly to it, because we would like to have TLS protection for its sensitve logs. If the router and the syslog relay are on a sufficiently secure private network, this setup can be considered reasonable secure. In any case, it is the best alternative among the possible configuration scenarios.

Steps to do:

  • make sure you have a functional CA (Setting up the CA)
  • generate a machine certificate for ada.example.net (follow instructions in Generating Machine Certificates)
  • make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the client. Ensure that no user except root can access them (even read permissions are really bad).
  • configure the client so that it checks the server identity and sends messages only if the server identity is known.

These were essentially the same steps as for any TLS syslog client. We now need to add the capability to forward the router logs:

  • make sure that the firewall rules permit message recpetion on UDP port 514 (if you use a non-standard port for UDP syslog, make sure that port number is permitted).
  • you may want to limit who can send syslog messages via UDP. A great place to do this is inside the firewall, but you can also do it in rsyslog.conf via an $AllowedSender directive. We have used one in the sample config below. Please be aware that this is a kind of weak authentication, but definitely better than nothing...
  • add the UDP input plugin to rsyslog's config and start a UDP listener
  • make sure that your forwarding-filter permits to forward messages received from the remote router to the server. In our sample scenario, we do not need to add anything special, because all messages are forwarded. This includes messages received from remote hosts.

At this point, please be reminded once again that your security needs may be quite different from what we assume in this tutorial. Evaluate your options based on your security needs.

Sample syslog.conf

Keep in mind that this rsyslog.conf sends messages via TCP, only. Also, we do not show any rules to write local files. Feel free to add them. 

# start a UDP listener for the remote router
$ModLoad imudp    # load UDP server plugin
$AllowedSender UDP, 192.0.2.1 # permit only the router
$UDPServerRun 514 # listen on default syslog UDP port 514

# make gtls driver the default
$DefaultNetstreamDriver gtls

# certificate files
$DefaultNetstreamDriverCAFile /rsyslog/protected/ca.pem
$DefaultNetstreamDriverCertFile /rsyslog/protected/machine-cert.pem
$DefaultNetstreamDriverKeyFile /rsyslog/protected/machine-key.pem

$ActionSendStreamDriverAuthMode x509/name
$ActionSendStreamDriverPermittedPeer central.example.net
$ActionSendStreamDriverMode 1 # run driver in TLS-only mode
*.* @@central.example.net:10514 # forward everything to remote server

Be sure to safeguard at least the private key (machine-key.pem)! If some third party obtains it, you security is broken!

Version Naming

This is the proposal on how versions should be named in the future:

Rsyslog version naming has undergone a number of changes in the past. Our sincere hopes is that the scheme outlined here will serve us well for the future. In general, a three-number versioning scheme with a potential development state indication is used. It follows this pattern:

major.minor.patchlevel[-devstate]

where devstate has some forther structure: -<releaseReason><releaseNumber>

All stable builds come without the devstate part. All unstable development version come with it.

The major version is incremented whenever something really important happens. A single new feature, even if important, does not justify an increase in the major version. There is no hard rule when the major version needs an increment. It mostly is a soft factor, when the developers and/or the community think there has been sufficient change to justify that. Major version increments are expected to happen quite infrequently, maybe around once a year. A major version increment has important implications from the support side: without support contracts, the current major version's last stable release and the last stable release of the version immediately below it are supported (Adiscon, the rsyslog sponsor, offers support contracts covering all other versions).

The minor version is incremented whenever a non-trivial new feature is planned to be added. Triviality of a feature is simply determined by time estimated to implement a feature. If that's more than a few days, it is considered a non-trivial feature. Whenever a new minor version is begun, the desired feature is identified and will be the primary focus of that major.minor version. Trivial features may justify a new minor version if they either do not look trivial from the user's point of view or change something quite considerable (so we need to alert users). A minor version increment may also be done for some other good reasons that the developers have.

The patchlevel is incremented whenever there is a bugfix or very minor feature added to a (stable or development) release.

The devstate is important during development of a feature. It helps the developers to release versions with new features to the general public and in the hope that this will result in some testing. To understand how it works, we need to look at the release cycle: As already said, at the start of a new minor version, a new non-trivial feature to be implemented in that version is selected. Development on this feature begins. At the current pace of development, getting initial support for such a non-trivial feature typically takes between two and four weeks. During this time, new feature requests come in. Also, we may find out that it may be just the right time to implement some not yet targeted feature requests. A reason for this is that the minor release's feature focus is easier to implement if the other feature is implemented first. This is a quite common thing to happen. So development on the primary focus may hold for a short period while we implement something else. Even unrelated, but very trivial feature requests (maybe an hour's worth of time to implement), may be done in between. Once we have implemented these things, we would like to release as quickly as possible (even more if someone has asked for the feature). So we do not like to wait for the original focus feature to be ready (what could take maybe three more weeks). As a result, we release the new features. But that version will also include partial code of the focus feature. Typically this doesn't hurt as long as noone tries to use it (what of course would miserably fail). But still, part of the new code is already in it. When we release such a "minor-feature enhanced" but "focus-feature not yet completed" version, we need a way to flag it. In current thinking, that is using a "-mf<version>" devstate in the version number ("mf" stands for "minor feature"). Version numbers for -mf releases start at 0 for the first release and are monotonically incremented. Once the focus feature has been fully implemented, a new version now actually supporting that feature will be released. Now, the release reason is changed to the well-know "-rc<version>" where "rc" stands for release candidate. For the first release candidate, the version starts at 0 again and is incremented monotonically for each subsequent release. Please note that a -rc0 may only have bare functionality but later -rc's have a richer one. If new minor features are implemented and released once we have reached rc stage, still a new rc version is issued. The difference between "mf" and "rc" is simply the presence of the desired feature. No support is provided for -mf versions once the first -rc version has been released. And only the most current -rc version is supported.

The -rc is removed and the version declared stable when we think it has undergone sufficient testing and look sufficiently well. Then, it'll turn into a stable release. Stable minor releases never receive non-trivial new features. There may be more than one -rc releases without a stable release present at the same time. In fact, most often we will work on the next minor development version while the previous minor version is still a -rc because it is not yet considered sufficiently stable.

Note: the absence of the -devstate part indicates that a release is stable. Following the same logic, any release with a -devstate part is unstable.

A quick sample: 

4.0.0 is the stable release. We begin to implement relp, moving to major.minor to 4.1. While we develop it, someone requests a trivial feature, which we implement. We need to release, so we will have 4.1.0-mf0. Another new feature is requested, move to 4.1.0-mf2. A first version of RELP is implemented: 4.1.0-rc0. A new trivial feature is implemented: 4.1.0-rc1. Relp is being enhanced: 4.1.0-rc2. We now feel RELP is good enough for the time being and begin to implement TLS on plain /Tcp syslog: logical increment to 4.2. Now another new feature in that tree: 4.2.0-mf0. Note that we now have 4.0.0 (stable) and 4.1.0-rc2 and 4.1.0-mf0 (both devel). We find a big bug in RELP coding. Two new releases: 4.1.0-rc3, 4.2.0-mf1 (the bug fix acts like a non-focus feature change). We release TLS: 4.2.0-rc0. Another RELP bug fix 4.1.0-rc4, 4.2.0-rc1. After a while, RELP is matured: 4.1.0 (stable). Now support for 4.0.x stable ends. It, however, is still provided for 3.x.x (in the actual case 2.x.x, because v3 was under the old naming scheme and now stable v3 was ever released).

This is how it is done so far:

This document briefly outlines the strategy for naming versions. It applies to versions 1.0.0 and above. Versions below that are all unstable and have a different naming schema.

Please note that version naming is currently being changed. There is a blog post about future rsyslog versions.

The major version is incremented whenever a considerate, major features have been added. This is expected to happen quite infrequently.

The minor version number is incremented whenever there is "sufficient need" (at the discretion of the developers). There is a notable difference between stable and unstable branches. The stable branch always has a minor version number in the range from 0 to 9. It is expected that the stable branch will receive bug and security fixes only. So the range of minor version numbers should be quite sufficient.

For the unstable branch, minor version numbers always start at 10 and are incremented as needed (again, at the discretion of the developers). Here, new minor versions include both fixes as well as new features (hopefully most of the time). They are expected to be released quite often.

The patch level (third number) is incremented whenever a really minor thing must be added to an existing version. This is expected to happen quite infrequently.

In general, the unstable branch carries all new development. Once it concludes with a sufficiently-enhanced, quite stable version, a new major stable version is assigned.

$ModDir

Type: global configuration directive

Default: system default for user libraries, e.g. /usr/local/lib/rsyslog/

Description:

Provides the default directory in which loadable modules reside. This may be used to specify an alternate location that is not based on the system default. If the system default is used, there is no need to specify this directive. Please note that it is vitally important to end the path name with a slash, else module loads will fail.

Sample:

$ModDir /usr/rsyslog/libs/  # note the trailing slash!

Actions

Action object describe what is to be done with a message. They are implemented via outpout modules.

The action object has different parameters:

  • those that apply to all actions and are action specific. These are documented below.
  • parameters for the action queue. While they also apply to all parameters, they are queue-specific, not action-specific (they are the same that are used in rulesets, for example).
  • action-specific parameters. These are specific to a certain type of actions. They are documented by the output module in question.

General Action Parameters

  • name word
    used for statistics gathering and documentation
  • type string
    Mandatory parameter for every action. The name of the module that should be used.
  • action.writeAllMarkMessages on/off
    Normally, mark messages are written to actions only if the action was not recently executed (by default, recently means within the past 20 minutes). If this setting is switched to "on", mark messages are always sent to actions, no matter how recently they have been executed. In this mode, mark messages can be used as a kind of heartbeat. Note that this option auto-resets to "off", so if you intend to use it with multiple actions, it must be specified in front off all selector lines that should provide this functionality.
  • action.execOnlyEveryNthTime integer
    If configured, the next action will only be executed every n-th time. For example, if configured to 3, the first two messages that go into the action will be dropped, the 3rd will actually cause the action to execute, the 4th and 5th will be dropped, the 6th executed under the action, ... and so on. Note: this setting is automatically re-set when the actual action is defined.
  • action.execOnlyEveryNthTimeout integer
    Has a meaning only if Action.ExecOnlyEveryNthTime is also configured for the same action. If so, the timeout setting specifies after which period the counting of "previous actions" expires and a new action count is begun. Specify 0 (the default) to disable timeouts. Why is this option needed? Consider this case: a message comes in at, eg., 10am. That's count 1. Then, nothing happens for the next 10 hours. At 8pm, the next one occurs. That's count 2. Another 5 hours later, the next message occurs, bringing the total count to 3. Thus, this message now triggers the rule. The question is if this is desired behavior? Or should the rule only be triggered if the messages occur within an e.g. 20 minute window? If the later is the case, you need a
    Action.ExecOnlyEveryNthTimeTimeout="1200"
    This directive will timeout previous messages seen if they are older than 20 minutes. In the example above, the count would now be always 1 and consequently no rule would ever be triggered.
  • action.execOnlyOnceEveryInterval integer
    Execute action only if the last execute is at last seconds in the past (more info in ommail, but may be used with any action)
  • action.execOnlyWhenpReviousIsSuspended on/off
    This directive allows to specify if actions should always be executed ("off," the default) or only if the previous action is suspended ("on"). This directive works hand-in-hand with the multiple actions per selector feature. It can be used, for example, to create rules that automatically switch destination servers or databases to a (set of) backup(s), if the primary server fails. Note that this feature depends on proper implementation of the suspend feature in the output module. All built-in output modules properly support it (most importantly the database write and the syslog message forwarder).
  • action.repeatedmsgcontainsoriginalmsg on/off
    "last message repeated n times" messages, if generated, have a different format that contains the message that is being repeated. Note that only the first "n" characters are included, with n to be at least 80 characters, most probably more (this may change from version to version, thus no specific limit is given). The bottom line is that n is large enough to get a good idea which message was repeated but it is not necessarily large enough for the whole message. (Introduced with 4.1.5). Once set, it affects all following actions.
  • action.resumeRetryCount integer
    [default 0, -1 means eternal]
  • action.resumeInterval integer
    Sets the ActionResumeInterval for the action. The interval provided is always in seconds. Thus, multiply by 60 if you need minutes and 3,600 if you need hours (not recommended). When an action is suspended (e.g. destination can not be connected), the action is resumed for the configured interval. Thereafter, it is retried. If multiple retires fail, the interval is automatically extended. This is to prevent excessive ressource use for retires. After each 10 retries, the interval is extended by itself. To be precise, the actual interval is (numRetries / 10 + 1) * Action.ResumeInterval. so after the 10th try, it by default is 60 and after the 100th try it is 330.

Legacy Format

Be warned that legacy action format is hard to get right. It is recommended to use RainerScript-Style action format whenever possible! A key problem with legacy format is that a single action is defined via multiple configurations lines, which may be spread all across rsyslog.conf. Even the definition of multiple actions may be intermixed (often not intentional!). If legacy actions format needs to be used (e.g. some modules may not yet implement the RainerScript format), it is strongly recommended to place all configuration statements pertaining to a single action closely together.

Please also note that legacy action parameters do not affect RainerScript action objects. So if you define for example: 

$actionResumeRetryCount 10
action(type="omfwd" target="server1.example.net")
@@server2.example.net
server1's "action.resumeRetryCount" parameter is not set, instead server2's is!

A goal of the new RainerScript action format was to avoid confusion which parameters are actually used. As such, it would be counter-productive to honor legacy action parameters inside a RainerScript definition. As result, both types of action definitions are strictly (and nicely) separated from each other. The bottom line is that if RainerScript actions are used, one does not need to care about which legacy action parameters may (still...) be in effect.

Note that not all modules necessarily support legacy action format. Especially newer modules are recommended to NOT support it.

Legacy Description

Templates can be used with many actions. If used, the specified template is used to generate the message content (instead of the default template). To specify a template, write a semicolon after the action value immediately followed by the template name.

Beware: templates MUST be defined BEFORE they are used. It is OK to define some templates, then use them in selector lines, define more templates and use use them in the following selector lines. But it is NOT permitted to use a template in a selector line that is above its definition. If you do this, the action will be ignored.

You can have multiple actions for a single selector  (or more precisely a single filter of such a selector line). Each action must be on its own line and the line must start with an ampersand ('&') character and have no filters. An example would be

*.=crit :omusrmsg:rger
& root
& /var/log/critmsgs

These three lines send critical messages to the user rger and root and also store them in /var/log/critmsgs. Using multiple actions per selector is convenient and also offers a performance benefit. As the filter needs to be evaluated only once, there is less computation required to process the directive compared to the otherwise-equal config directives below:

*.=crit :omusrmsg:rger
*.=crit root
*.=crit /var/log/critmsgs

 

Regular File

Typically messages are logged to real files. The file usually is specified by full pathname, beginning with a slash "/". Starting with version 4.6.2 and 5.4.1 (previous v5 version do NOT support this) relative file names can also be specified. To do so, these must begin with a dot. For example, use "./file-in-current-dir.log" to specify a file in the current directory. Please note that rsyslogd usually changes its working directory to the root, so relative file names must be tested with care (they were introduced primarily as a debugging vehicle, but may have useful other applications as well).


You may prefix each entry with the minus "-'' sign to omit syncing the file after every logging. Note that you might lose information if the system crashes right behind a write attempt. Nevertheless this might give you back some performance, especially if you run programs that use logging in a very verbose manner.

If your system is connected to a reliable UPS and you receive lots of log data (e.g. firewall logs), it might be a very good idea to turn of syncing by specifying the "-" in front of the file name.

The filename can be either static (always the same) or dynamic (different based on message received). The later is useful if you would automatically split messages into different files based on some message criteria. For example, dynamic file name selectors allow you to split messages into different files based on the host that sent them. With dynamic file names, everything is automatic and you do not need any filters.

It works via the template system. First, you define a template for the file name. An example can be seen above in the description of template. We will use the "DynFile" template defined there. Dynamic filenames are indicated by specifying a questions mark "?" instead of a slash, followed by the template name. Thus, the selector line for our dynamic file name would look as follows:

*.* ?DynFile

That's all you need to do. Rsyslog will now automatically generate file names for you and store the right messages into the right files. Please note that the minus sign also works with dynamic file name selectors. Thus, to avoid syncing, you may use

*.* -?DynFile

And of course you can use templates to specify the output format:

*.* ?DynFile;MyTemplate

A word of caution: rsyslog creates files as needed. So if a new host is using your syslog server, rsyslog will automatically create a new file for it.

Creating directories is also supported. For example you can use the hostname as directory and the program name as file name:

$template DynFile,"/var/log/%HOSTNAME%/%programname%.log"

Named Pipes

This version of rsyslogd(8) has support for logging output to named pipes (fifos). A fifo or named pipe can be used as a destination for log messages by prepending a pipe symbol ("|'') to the name of the file. This is handy for debugging. Note that the fifo must be created with the mkfifo(1) command before rsyslogd(8) is started.

Terminal and Console

If the file you specified is a tty, special tty-handling is done, same with /dev/console.

Remote Machine

Rsyslogd provides full remote logging, i.e. is able to send messages to a remote host running rsyslogd(8) and to receive messages from remote hosts. Using this feature you're able to control all syslog messages on one host, if all other machines will log remotely to that. This tears down administration needs.

To forward messages to another host, prepend the hostname with the at sign ("@"). A single at sign means that messages will be forwarded via UDP protocol (the standard for syslog). If you prepend two at signs ("@@"), the messages will be transmitted via TCP. Please note that plain TCP based syslog is not officially standardized, but most major syslogds support it (e.g. syslog-ng or WinSyslog). The forwarding action indicator (at-sign) can be followed by one or more options. If they are given, they must be immediately (without a space) following the final at sign and be enclosed in parenthesis. The individual options must be separated by commas. The following options are right now defined:

z<number>

 Enable zlib-compression for the message. The <number> is the compression level. It can be 1 (lowest gain, lowest CPU overhead) to 9 (maximum compression, highest CPU overhead). The level can also be 0, which means "no compression". If given, the "z" option is ignored. So this does not make an awful lot of sense. There is hardly a difference between level 1 and 9 for typical syslog messages. You can expect a compression gain between 0% and 30% for typical messages. Very chatty messages may compress up to 50%, but this is seldom seen with typically traffic. Please note that rsyslogd checks the compression gain. Messages with 60 bytes or less will never be compressed. This is because compression gain is pretty unlikely and we prefer to save CPU cycles. Messages over that size are always compressed. However, it is checked if there is a gain in compression and only if there is, the compressed message is transmitted. Otherwise, the uncompressed messages is transmitted. This saves the receiver CPU cycles for decompression. It also prevents small message to actually become larger in compressed form.

Please note that when a TCP transport is used, compression will also turn on syslog-transport-tls framing. See the "o" option for important information on the implications.

Compressed messages are automatically detected and decompressed by the receiver. There is nothing that needs to be configured on the receiver side.

o

 This option is experimental. Use at your own risk and only if you know why you need it! If in doubt, do NOT turn it on.

This option is only valid for plain TCP based transports. It selects a different framing based on IETF internet draft syslog-transport-tls-06. This framing offers some benefits over traditional LF-based framing. However, the standardization effort is not yet complete. There may be changes in upcoming versions of this standard. Rsyslog will be kept in line with the standard. There is some chance that upcoming changes will be incompatible to the current specification. In this case, all systems using -transport-tls framing must be upgraded. There will be no effort made to retain compatibility between different versions of rsyslog. The primary reason for that is that it seems technically impossible to provide compatibility between some of those changes. So you should take this note very serious. It is not something we do not *like* to do (and may change our mind if enough people beg...), it is something we most probably *can not* do for technical reasons (aka: you can beg as much as you like, it won't change anything...).

The most important implication is that compressed syslog messages via TCP must be considered with care. Unfortunately, it is technically impossible to transfer compressed records over traditional syslog plain tcp transports, so you are left with two evil choices...


The hostname may be followed by a colon and the destination port.

The following is an example selector line with forwarding:

*.*    @@(o,z9)192.168.0.1:1470

In this example, messages are forwarded via plain TCP with experimental framing and maximum compression to the host 192.168.0.1 at port 1470.

*.* @192.168.0.1

In the example above, messages are forwarded via UDP to the machine 192.168.0.1, the destination port defaults to 514. Messages will not be compressed.

Note that IPv6 addresses contain colons. So if an IPv6 address is specified in the hostname part, rsyslogd could not detect where the IP address ends and where the port starts. There is a syntax extension to support this: put squary brackets around the address (e.g. "[2001::1]"). Square brackets also work with real host names and IPv4 addresses, too.

A valid sample to send messages to the IPv6 host 2001::1 at port 515 is as follows:

*.* @[2001::1]:515

This works with TCP, too.

Note to sysklogd users: sysklogd does not support RFC 3164 format, which is the default forwarding template in rsyslog. As such, you will experience duplicate hostnames if rsyslog is the sender and sysklogd is the receiver. The fix is simple: you need to use a different template. Use that one:

$template sysklogd,"<%PRI%>%TIMESTAMP% %syslogtag%%msg%\""
*.* @192.168.0.1;sysklogd

List of Users

Usually critical messages are also directed to "root'' on that machine. You can specify a list of users that shall get the message by simply writing ":omusrmsg: followed by the login name. For example, the send messages to root, use ":omusrmsg:root". You may specify more than one user by separating them with commas (",''). Do not repeat the ":omusrmsg:" prefix in this case. For example, to send data to users root and rger, use ":omusrmsg:root,rger" (do not use ":omusrmsg:root,:omusrmsg:rger", this is invalid). If they're logged in they get the message.

Everyone logged on

Emergency messages often go to all users currently online to notify them that something strange is happening with the system. To specify this wall(1)-feature use an asterisk as the user message destination(":omusrmsg:*'').

Call Plugin

This is a generic way to call an output plugin. The plugin must support this functionality. Actual parameters depend on the module, so see the module's doc on what to supply. The general syntax is as follows:

:modname:params;template

Currently, the ommysql database output module supports this syntax (in addtion to the ">" syntax it traditionally supported). For ommysql, the module name is "ommysql" and the params are the traditional ones. The ;template part is not module specific, it is generic rsyslog functionality available to all modules.

As an example, the ommysql module may be called as follows:

:ommysql:dbhost,dbname,dbuser,dbpassword;dbtemplate

For details, please see the "Database Table" section of this documentation.

Note: as of this writing, the ":modname:" part is hardcoded into the module. So the name to use is not necessarily the name the module's plugin file is called.

Database Table

This allows logging of the message to a database table. Currently, only MySQL databases are supported. However, other database drivers will most probably be developed as plugins. By default, a MonitorWare-compatible schema is required for this to work. You can create that schema with the createDB.SQL file that came with the rsyslog package. You can also
use any other schema of your liking - you just need to define a proper template and assign this template to the action.

The database writer is called by specifying a greater-then sign (">") in front of the database connect information. Immediately after that
sign the database host name must be given, a comma, the database name, another comma, the database user, a comma and then the user's password. If a specific template is to be used, a semicolon followed by the template name can follow the connect information. This is as follows:

>dbhost,dbname,dbuser,dbpassword;dbtemplate

Important: to use the database functionality, the MySQL output module must be loaded in the config file BEFORE the first database table action is used. This is done by placing the

$ModLoad ommysql

directive some place above the first use of the database write (we recommend doing at the the beginning of the config file).

Discard

If the discard action is carried out, the received message is immediately discarded. No further processing of it occurs. Discard has primarily been added to filter out messages before carrying on any further processing. For obvious reasons, the results of "discard" are depending on where in the configuration file it is being used. Please note that once a message has been discarded there is no way to retrieve it in later configuration file lines.

Discard can be highly effective if you want to filter out some annoying messages that otherwise would fill your log files. To do that, place the discard actions early in your log files. This often plays well with property-based filters, giving you great freedom in specifying what you do not want.

Discard is just the single tilde character with no further parameters:

~

For example,

*.*   ~

discards everything (ok, you can achive the same by not running rsyslogd at all...).

Output Channel

Binds an output channel definition (see there for details) to this action. Output channel actions must start with a $-sign, e.g. if you would like to bind your output channel definition "mychannel" to the action, use "$mychannel". Output channels support template definitions like all all other actions.

Shell Execute

This executes a program in a subshell. The program is passed the template-generated message as the only command line parameter. Rsyslog waits until the program terminates and only then continues to run.

^program-to-execute;template

The program-to-execute can be any valid executable. It receives the template string as a single parameter (argv[1]).

WARNING: The Shell Execute action was added to serve an urgent need. While it is considered reasonable save when used with some thinking, its implications must be considered. The current implementation uses a system() call to execute the command. This is not the best way to do it (and will hopefully changed in further releases). Also, proper escaping of special characters is done to prevent command injection. However, attackers always find smart ways to circumvent escaping, so we can not say if the escaping applied will really safe you from all hassles. Lastly, rsyslog will wait until the shell command terminates. Thus, a program error in it (e.g. an infinite loop) can actually disable rsyslog. Even without that, during the programs run-time no messages are processed by rsyslog. As the IP stacks buffers are quickly overflowed, this bears an increased risk of message loss. You must be aware of these implications. Even though they are severe, there are several cases where the "shell execute" action is very useful. This is the reason why we have included it in its current form. To mitigate its risks, always a) test your program thoroughly, b) make sure its runtime is as short as possible (if it requires a longer run-time, you might want to spawn your own sub-shell asynchronously), c) apply proper firewalling so that only known senders can send syslog messages to rsyslog. Point c) is especially important: if rsyslog is accepting message from any hosts, chances are much higher that an attacker might try to exploit the "shell execute" action.

Template Name

Every ACTION can be followed by a template name. If so, that template is used for message formatting. If no name is given, a hard-coded default template is used for the action. There can only be one template name for each given action. The default template is specific to each action. For a description of what a template is and what you can do with it, see "TEMPLATES" at the top of this document.

ruleset output/including module (omruleset)

Module Name:    omruleset

Author: Rainer Gerhards <rgerhards@adiscon.com>

Available Since: 5.3.4

Description:

This is a very special "output" module. It permits to pass a message object to another rule set. While this is a very simple action, it enables very complex configurations, e.g. it supports high-speed "and" conditions, sending data to the same file in a non-racy way, include-ruleset functionality as well as some high-performance optimizations (in case the rule sets have the necessary queue definitions).

While it leads to a lot of power, this output module offers seamingly easy functionaltiy. The complexity (and capablities) arise from how everthing can be combined.

With this module, a message can be sent to processing to another ruleset. This is somewhat similar to a "#include" in the C programming language. However, one needs to keep on the mind that a ruleset can contain its own queue and that a queue can run in various modes.

Note that if no queue is defined in the ruleset, the message is enqueued into the main message queue. This most often is not optimal and means that message processing may be severely defered. Also note that when the ruleset's target queue is full and no free space can be aquired within the usual timeout, the message object may actually be lost. This is an extreme scenario, but users building an audit-grade system need to know this restriction. For regular installations, it should not really be relevant.

At minimum, be sure you understand the $RulesetCreateMainQueue directive as well as the importance of statement order in rsyslog.conf before using omruleset!

Recommended Use:

  • create rulesets specifically for omruleset
  • create these rulesets with their own main queue
  • decent queueing parameters (sizes, threads, etc) should be used for the ruleset main queue. If in doubt, use the same parameters as for the overall main queue.
  • if you use multiple levels of ruleset nesting, double check for endless loops - the rsyslog engine does not detect these

Configuration Directives:

  • $ActionOmrulesetRulesetName ruleset-to-submit-to
    This directive specifies the name of the ruleset that the message provided to omruleset should be submitted to. This ruleset must already have been defined. Note that the directive is automatically reset after each :omruleset: action and there is no default. This is done to prevent accidential loops in ruleset definition, what can happen very quickly. The :omruleset: action will NOT be honored if no ruleset name has been defined. As usual, the ruleset name must be specified in front of the action that it modifies.

Examples:

This example creates a ruleset for a write-to-file action. The idea here is that the same file is written based on multiple filters, problems occur if the file is used together with a buffer. That is because file buffers are action-specific, and so some partial buffers would be written. With omruleset, we create a single action inside its own ruleset and then pass all messages to it whenever we need to do so. Of course, such a simple situation could also be solved by a more complex filter, but the method used here can also be utilized in more complex scenarios (e.g. with multiple listeners). The example tries to keep it simple. Note that we create a ruleset-specific main queue (for simplicity with the default main queue parameters) in order to avoid re-queueing messages back into the main queue.

The next example is used to creat a high-performance nested and filter condition. Here, it is first checked if the message contains a string "error". If so, the message is forwarded to another ruleset which then applies some filters. The advantage of this is that we can use high-performance filters where we otherwise would need to use the (much slower) expression-based filters. Also, this enables pipeline processing, in that second ruleset is executed in parallel to the first one.

Caveats/Known Bugs:

The current configuration file language is not really adequate for a complex construct like omruleset. Unfortunately, more important work is currently preventing me from redoing the config language. So use extreme care when nesting rulesets and be sure to test-run your config before putting it into production, ensuring you have a suffciently large probe of the traffic run over it. If problems arise, the rsyslog debug log is your friend.

Multiple Rulesets in rsyslog

Starting with version 4.5.0 and 5.1.1, rsyslog supports multiple rulesets within a single configuration. This is especially useful for routing the recpetion of remote messages to a set of specific rules. Note that the input module must support binding to non-standard rulesets, so the functionality may not be available with all inputs.

Attention: this guide is shortened and only contains the samples in legacy format. Please follow this link to the full guide in the new config format "list": http://www.rsyslog.com/doc/multi_ruleset.html

Examples

Split local and remote logging

Let's say you have a pretty standard system that logs its local messages to the usual bunch of files that are specified in the default rsyslog.conf. As an example, your rsyslog.conf might look like this: 

# ... module loading ...
# The authpriv file has restricted access.
authpriv.*  /var/log/secure
# Log all the mail messages in one place.
mail.*      /var/log/maillog
# Log cron stuff
cron.*      /var/log/cron
# Everybody gets emergency messages
*.emerg     *
... more ...

Now, you want to add receive messages from a remote system and log these to a special file, but you do not want to have these messages written to the files specified above. The traditional approach is to add a rule in front of all others that filters on the message, processes it and then discards it: 

# ... module loading ...
# process remote messages
:fromhost-ip, isequal, "192.0.2.1"    /var/log/remotefile
& ~
# only messages not from 192.0.21 make it past this point

# The authpriv file has restricted access.
authpriv.*                            /var/log/secure
# Log all the mail messages in one place.
mail.*                                /var/log/maillog
# Log cron stuff
cron.*                                /var/log/cron
# Everybody gets emergency messages
*.emerg                               *
... more ...

Note the tilde character, which is the discard action!. Also note that we assume that 192.0.2.1 is the sole remote sender (to keep it simple).

With multiple rulesets, we can simply define a dedicated ruleset for the remote reception case and bind it to the receiver. This may be written as follows: 

# ... module loading ...
# process remote messages
# define new ruleset and add rules to it:
$RuleSet remote
*.*           /var/log/remotefile
# only messages not from 192.0.21 make it past this point

# bind ruleset to tcp listener
$InputTCPServerBindRuleset remote
# and activate it:
$InputTCPServerRun 10514

# switch back to the default ruleset:
$RuleSet RSYSLOG_DefaultRuleset
# The authpriv file has restricted access.
authpriv.*    /var/log/secure
# Log all the mail messages in one place.
mail.*        /var/log/maillog
# Log cron stuff
cron.*        /var/log/cron
# Everybody gets emergency messages
*.emerg       *
... more ...

Here, we need to switch back to the default ruleset after we have defined our custom one. This is why I recommend a different ordering, which I find more intuitive. The sample below has it, and it leads to the same results: 

# ... module loading ...
# at first, this is a copy of the unmodified rsyslog.conf
# The authpriv file has restricted access.
authpriv.*    /var/log/secure
# Log all the mail messages in one place.
mail.*        /var/log/maillog
# Log cron stuff
cron.*        /var/log/cron
# Everybody gets emergency messages
*.emerg       *
... more ...
# end of the "regular" rsyslog.conf. Now come the new definitions:

# process remote messages
# define new ruleset and add rules to it:
$RuleSet remote
*.*           /var/log/remotefile

# bind ruleset to tcp listener
$InputTCPServerBindRuleset remote
# and activate it:
$InputTCPServerRun 10514

Here, we do not switch back to the default ruleset, because this is not needed as it is completely defined when we begin the "remote" ruleset.

Now look at the examples and compare them to the single-ruleset solution. You will notice that we do not need a real filter in the multi-ruleset case: we can simply use "*.*" as all messages now means all messages that are being processed by this rule set and all of them come in via the TCP receiver! This is what makes using multiple rulesets so much easier.

Split local and remote logging for three different ports

This example is almost like the first one, but it extends it a little bit. While it is very similar, I hope it is different enough to provide a useful example why you may want to have more than two rulesets.

Again, we would like to use the "regular" log files for local logging, only. But this time we set up three syslog/tcp listeners, each one listening to a different port (in this example 10514, 10515, and 10516). Logs received from these receivers shall go into different files. Also, logs received from 10516 (and only from that port!) with "mail.*" priority, shall be written into a specif file and not be written to 10516's general log file.

This is the config: 

# ... module loading ...
# at first, this is a copy of the unmodified rsyslog.conf
# The authpriv file has restricted access.
authpriv.* /var/log/secure
# Log all the mail messages in one place.
mail.*  /var/log/maillog
# Log cron stuff
cron.*  /var/log/cron
# Everybody gets emergency messages
*.emerg       *
... more ...
# end of the "regular" rsyslog.conf. Now come the new definitions:

# process remote messages

#define rulesets first
$RuleSet remote10514
*.*     /var/log/remote10514

$RuleSet remote10515
*.*     /var/log/remote10515

$RuleSet remote10516
mail.*	/var/log/mail10516
&       ~
# note that the discard-action will prevent this messag from 
# being written to the remote10516 file - as usual...
*.*     /var/log/remote10516

# and now define listeners bound to the relevant ruleset
$InputTCPServerBindRuleset remote10514
$InputTCPServerRun 10514

$InputTCPServerBindRuleset remote10515
$InputTCPServerRun 10515

$InputTCPServerBindRuleset remote10516
$InputTCPServerRun 10516

Note that the "mail.*" rule inside the "remote10516" ruleset does not affect processing inside any other rule set, including the default rule set.

$ModLoad

Type: global configuration directive

Default:

Description:

Dynamically loads a plug-in into rsyslog's address space and activates it. The plug-in must obey the rsyslog module API. Currently, only MySQL and Postgres output modules are available as a plugins, but users may create their own. A plug-in must be loaded BEFORE any configuration file lines that reference it.

Modules must be present in the system default destination for rsyslog modules. You can also set the directory via the $ModDir directive.

If a full path name is specified, the module is loaded from that path. The default module directory is ignored in that case.

Sample:

$ModLoad ommysql # load MySQL functionality
$ModLoad /rsyslog/modules/ompgsql.so # load the postgres module via absolute path

syslog-protocol support in rsyslog

Rsyslog  provides a trial implementation of the proposed syslog-protocol standard. The intention of this implementation is to find out what inside syslog-protocol is causing problems during implementation. As syslog-protocol is a standard under development, its support in rsyslog is highly volatile. It may change from release to release. So while it provides some advantages in the real world, users are cautioned against using it right now. If you do, be prepared that you will probably need to update all of your rsyslogds with each new release. If you try it anyhow, please provide feedback as that would be most beneficial for us.

Currently supported message format

Due to recent discussion on syslog-protocol, we do not follow any specific revision of the draft but rather the candidate ideas. The format supported currently is:

<PRI>VERSION SP TIMESTAMP SP HOSTNAME SP APP-NAME SP PROCID SP MSGID SP [SD-ID]s SP MSG

Field syntax and semantics are as defined in IETF I-D syslog-protocol-15.

Capabilities Implemented

  • receiving message in the supported format (see above)
  • sending messages in the supported format
  • relaying messages
  • receiving messages in either legacy or -protocol format and transforming them into the other one
  • virtual availability of TAG, PROCID, APP-NAME, MSGID, SD-ID no matter if the message was received via legacy format, API or syslog-protocol format (non-present fields are being emulated with great success)
  • maximum message size is set via preprocessor #define
  • syslog-protocol messages can be transmitted both over UDP and plain TCP with some restrictions on compliance in the case of TCP

Findings

This lists what has been found during implementation:

  • The same receiver must be able to support both legacy and syslog-protocol syslog messages. Anything else would be a big inconvenience to users and would make deployment much harder. The detection must be done automatically (see below on how easy that is).
  • NUL characters inside MSG cause the message to be truncated at that point. This is probably a major point for many C-based implementations. No measures have yet been taken against this. Modifying the code to "cleanly" support NUL characters is non-trivial, even though rsyslogd already has some byte-counted string library (but this is new and not yet available everywhere).
  • character encoding in MSG: is is problematic to do the right UTF-8 encoding. The reason is that we pick up the MSG from the local domain socket (which got it from the syslog(3) API). The text obtained does not include any encoding information, but it does include non US-ASCII characters. It may also include any other encoding. Other than by guessing based on the provided text, I have no way to find out what it is. In order to make the syslogd do anything useful, I have now simply taken the message as is and stuffed it into the MSG part. Please note that I think this will be a route that other implementors would take, too.
  • A minimal parser is easy to implement. It took me roughly 2 hours to add it to rsyslogd. This includes the time for restructuring the code to be able to parse both legacy syslog as well as syslog-protocol. The parser has some restrictions, though
    • STRUCTURED-DATA field is extracted, but not validated. Structured data "[test ]]" is not caught as an error. Nor are any other errors caught. For my needs with this syslogd, that level of structured data processing is probably sufficient. I do not want to parse/validate it in all cases. This is also a performance issue. I think other implementors could have the same view. As such, we should not make validation a requirement.
    • MSG is not further processed (e.g. Unicode not being validated)
    • the other header fields are also extracted, but no validation is performed right now. At least some validation should be easy to add (not done this because it is a proof-of-concept and scheduled to change).
  • Universal access to all syslog fields (missing ones being emulated) was also quite easy. It took me around another 2 hours to integrate emulation of non-present fields into the code base.
  • The version at the start of the message makes it easy to detect if we have legacy syslog or syslog-protocol. Do NOT move it to somewhere inside the middle of the message, that would complicate things. It might not be totally fail-safe to just rely on "1 " as the "cookie" for a syslog-protocol. Eventually, it would be good to add some more uniqueness, e.g. "@#1 ".
  • I have no (easy) way to detect truncation if that happens on the UDP stack. All I see is that I receive e.g. a 4K message. If the message was e.g. 6K, I received two chunks. The first chunk (4K) is correctly detected as a syslog-protocol message, the second (2K) as legacy syslog. I do not see what we could do against this. This questions the usefulness of the TRUNCATE bit. Eventually, I could look at the UDP headers and see that it is a fragment. I have looked at a network sniffer log of the conversation. This looks like two totally-independent messages were sent by the sender stack.
  • The maximum message size is currently being configured via a preprocessor #define. It can easily be set to 2K or 4K, but more than 4K is not possible because of UDP stack limitations. Eventually, this can be worked around, but I have not done this yet.
  • rsyslogd can accept syslog-protocol formatted messages but is able to relay them in legacy format. I find this a must in real-life deployments. For this, I needed to do some field mapping so that APP-NAME/PROCID are mapped into a TAG.
  • rsyslogd can also accept legacy syslog message and relay them in syslog-protocol format. For this, I needed to apply some sub-parsing of the TAG, which on most occasions provides correct results. There might be some misinterpretations but I consider these to be mostly non-intrusive.
  • Messages received from the syslog API (the normal case under *nix) also do not have APP-NAME and PROCID and I must parse them out of TAG as described directly above. As such, this algorithm is absolutely vital to make things work on *nix.
  • I have an issue with messages received via the syslog(3) API (or, to be more precise, via the local domain socket this API writes to): These messages contain a timestamp, but that timestamp does neither have the year nor the high-resolution time. The year is no real issue, I just take the year of the reception of that message. There is a very small window of exposure for messages read from the log immediately after midnight Jan 1st. The message in the domain socket might have been written immediately before midnight in the old year. I think this is acceptable. However, I can not assign a high-precision timestamp, at least it is somewhat off if I take the timestamp from message reception on the local socket. An alternative might be to ignore the timestamp present and instead use that one when the message is pulled from the local socket (I am talking about IPC, not the network - just a reminder...). This is doable, but eventually not advisable. It looks like this needs to be resolved via a configuration option.
  • rsyslogd already advertised its origin information on application startup (in a syslog-protocol-14 compatible format). It is fairly easy to include that with any message if desired (not currently done).
  • A big problem I noticed are malformed messages. In -syslog-protocol, we recommend/require to discard malformed messages. However, in practice users would like to see everything that the syslogd receives, even if it is in error. For the first version, I have not included any error handling at all. However, I think I would deliberately ignore any "discard" requirement. My current point of view is that in my code I would eventually flag a message as being invalid and allow the user to filter on this invalidness. So these invalid messages could be redirected into special bins.
  • The error logging recommendations (those I insisted on;)) are not really practical. My application has its own error logging philosophy and I will not change this to follow a draft.
  • Relevance of support for leap seconds and senders without knowledge of time is questionable. I have not made any specific provisions in the code nor would I know how to handle that differently. I could, however, pull the local reception timestamp in this case, so it might be useful to have this feature. I do not think any more about this for the initial proof-of-concept. Note it as a potential problem area, especially when logging to databases.
  • The HOSTNAME field for internally generated messages currently contains the hostname part only, not the FQDN. This can be changed inside the code base, but it requires some thinking so that thinks are kept compatible with legacy syslog. I have not done this for the proof-of-concept, but I think it is not really bad. Maybe an hour or half a day of thinking.
  • It is possible that I did not receive a TAG with legacy syslog or via the syslog API. In this case, I can not generate the APP-NAME. For consistency, I have used "-" in such cases (just like in PROCID, MSGID and STRUCTURED-DATA).
  • As an architectural side-effect, syslog-protocol formatted messages can also be transmitted over non-standard syslog/raw tcp. This implementation uses the industry-standard LF termination of tcp syslog records. As such, syslog-protocol messages containing a LF will be broken invalidly. There is nothing that can be done against this without specifying a TCP transport. This issue might be more important than one thinks on first thought. The reason is the wide deployment of syslog/tcp via industry standard.

Some notes on syslog-transport-udp-06

  • I did not make any low-level modifications to the UDP code and think I am still basically covered with this I-D.
  • I deliberately violate section 3.3 insofar as that I do not necessarily accept messages destined to port 514. This feature is user-required and a must. The same applies to the destination port. I am not sure if the "MUST" in section 3.3 was meant that this MUST be an option, but not necessarily be active. The wording should be clarified.
  • section 3.6: I do not check checksums. See the issue with discarding messages above. The same solution will probably be applied in my code.

 

Conlusions/Suggestions

These are my personal conclusions and suggestions. Obviously, they must be discussed ;)

  • NUL should be disallowed in MSG
  • As it is not possible to definitely know the character encoding of the application-provided message, MSG should not be specified to use UTF-8 exclusively. Instead, it is suggested that any encoding may be used but UTF-8 is preferred. To detect UTF-8, the MSG should start with the UTF-8 byte order mask of "EF BB BF" if it is UTF-8 encoded (see section 155.9 of http://www.unicode.org/versions/Unicode4.0.0/ch15.pdf)
  • Requirements to drop messages should be reconsidered. I guess I would not be the only implementor ignoring them.
  • Logging requirements should be reconsidered and probably be removed.
  • It would be advisable to specify "-" for APP-NAME is the name is not known to the sender.
  • The implications of the current syslog/tcp industry standard on syslog-protocol should be further evaluated and be fully understood

$DropMsgsWithMaliciousDnsPTRRecords

Type: global configuration directive

Default: off

Description:

Rsyslog contains code to detect malicious DNS PTR records (reverse name resolution). An attacker might use specially-crafted DNS entries to make you think that a message might have originated on another IP address. Rsyslog can detect those cases. It will log an error message in any case. If this option here is set to "on", the malicious message will be completely dropped from your logs. If the option is set to "off", the message will be logged, but the original IP will be used instead of the DNS name.

Welcome to rsyslog

Rsyslog is an enhanced syslogd suitable both for small systems as well as large enterprises.

This page provide a few quick pointers which hopefully make your experience with rsyslog a pleasant one. These are

  • Most importantly, the rsyslog manual - this points to locally installed documentation which exactly matches the version you have installed. It is highly suggested to at least briefly look over these files.
  • The rsyslog web site which offers probably every information you'll ever need (ok, just kidding...).
  • The project status page provides information on current releases
  • and the troubleshooting guide hopefully helps if things do not immediately work out

In general, rsyslog supports plain old syslog.conf format, except that the config file is now called rsyslog.conf. This should help you get started quickly. To do the really cool things, though, you need to learn a bit about its new features. The man pages offer a bare minimum of information (and are still quite long). Read the html documentation instead. When you change the configuration, remember to restart rsyslogd, because otherwise it will not use your new settings (and you'll end up totally puzzled why this great config of yours does not even work a bit...;)) rsyslog-7.4.4/doc/rsconf1_generateconfiggraph.html0000664000175000017500000001765711736765143017300 00000000000000 rsyslog.conf file back

$GenerateConfigGraph

Type: global configuration directive

Default:

Available Since: 4.3.1 CURRENTLY NOT AVAILABLE

Description:

This directive is currently not supported. We had to disable it when we improved the rule engine. It is considerable effort to re-enable it. On the other hand, we are about to add a new config system, which will make yet another config graph method necessary. As such we have decided to currently disable this functionality and re-introduce it when the new config system has been instantiated.

This directive permits to create (hopefully) good-looking visualizations of rsyslogd's configuration. It does not affect rsyslog operation. If the directive is specified multiple times, all but the last are ignored. If it is specified, a graph is created. This happens both during a regular startup as well a config check run. It is recommended to include this directive only for documentation purposes and remove it from a production configuraton.

The graph is not drawn by rsyslog itself. Instead, it uses the great open source tool Graphviz to do the actual drawing. This has at least two advantages:

  • the graph drawing support code in rsyslog is extremly slim and without overhead
  • the user may change or further annotate the generated file, thus potentially improving his documentation
The drawback, of course, is that you need to run Graphviz once you have generated the control file with rsyslog. Fortunately, the process to do so is rather easy:
  1. add "$GenerateConfigGraph /path/to/file.dot" to rsyslog.conf (from now on, I will call the file just file.dot). Optionally, add "$ActionName" statement in front of those actions that you like to use friendly names with. If you do this, keep the names short.
  2. run rsyslog at least once (either in regular or configuration check mode)
  3. remember to remove the $GenerateConfigGraph directive when you no longer need it (or comment it out)
  4. change your working directory to where you place the dot file
  5. if you would like to edit the rsyslog-generated file, now is the time to do so
  6. do "dot -Tpng file.dot > file.png"
  7. remember that you can use "convert -resize 50% file.png resized.png" if dot's output is too large (likely) or too small. Resizing can be especially useful if you intend to get a rough overview over your configuration.
After completing these steps, you should have a nice graph of your configuration. Details are missing, but that is exactly the point. At the start of the graph is always (at least in this version, could be improved) a node called "inputs" in a tripple hexagon shape. This represents all inputs active in the system (assuming you have defined some, what the current version does not check). Next comes the main queue. It is given in a hexagon shape. That shape indicates that a queue is peresent and used to de-couple the inbound from the outbound part of the graph. In technical terms, here is a threading boundary. Action with "real" queues (other than in direct mode) also utilize this shape. For actions, notice that a "hexagon action" creates a deep copy of the message. As such, a "discard hexagon action" actually does nothing, because it duplicates the message and then discards the duplicate. At the end of the diagram, you always see a "discard" action. This indicates that rsyslog discards messages which have been run through all available rules.

Edges are labeled with information about when they are taken. For filters, the type of filter, but not any specifics, are given. It is also indicated if no filter is applied in the configuration file (by using a "*.*" selector). Edges without labels are unconditionally taken. The actions themselfs are labeled with the name of the output module that handles them. If provided, the name given via "ActionName" is used instead. No further details are provided.

If there is anything in red, this should draw your attention. In this case, rsyslogd has detected something that does not look quite right. A typical example is a discard action which is followed by some other actions in an action unit. Even though something may be red, it can be valid - rsyslogd's graph generator does not yet check each and every speciality, so the configuration may just cover a very uncommon case.

Now let's look at some examples. The graph below was generated on a fairly standard Fedora rsyslog.conf file. It had only the usually commented-out last forwarding action activated:

rsyslog configuration graph for a default fedora rsyslog.conf

This is the typical structure for a simple rsyslog configuration. There are a couple of actions, each guarded by a filter. Messages run from top to bottom and control branches whenever a filter evaluates to true. As there is no discard action, all messages will run through all filters and discarded in the system default discard action right after all configured actions.

A more complex example can be seen in the next graph. This is a configuration I created for testing the graph-creation features, so it contains a little bit of everything. However, real-world configurations can look quite complex, too (and I wouldn't say this one is very complex):

Here, we have a user-defined discard action. You can immediately see this because processing branches after the first "builtin-file" action. Those messages where the filter evaluates to true for will never run through the left-hand action branch. However, there is also a configuration error present: there are two more actions (now shown red) after the discard action. As the message is discarded, these will never be executed. Note that the discard branch contains no further filters. This is because these actions are all part of the same action unit, which is guarded only by an entry filter. The same is present a bit further down at the node labeled "write_system_log_2". This note has one more special feature, that is label was set via "ActionName", thus is does not have standard form (the same happened to the node named "Forward" right at the top of the diagram. Inside this diagram, the "Forward" node is executed asynchonously on its own queue. All others are executed synchronously.

Configuration graphs are useful for documenting a setup, but are also a great troubleshooting resource. It is important to remember that these graphs are generated from rsyslogd's in-memory action processing structures. You can not get closer to understanding on how rsyslog interpreted its configuration files. So if the graph does not look what you intended to do, there is probably something worng in rsyslog.conf.

If something is not working as expected, but you do not spot the error immediately, I recommend to generate a graph and zoom it so that you see all of it in one great picture. You may not be able to read anything, but the structure should look good to you and so you can zoom into those areas that draw your attention.

GSSAPI module support in rsyslog v3

What is it good for.

  • client-serverauthentication
  • Log messages encryption

Requirements.

  • Kerberos infrastructure
  • rsyslog, rsyslog-gssapi

Configuration.

Let's assume there are 3 machines in kerberos Realm:

  • the first is running KDC (Kerberos Authentication Service and Key Distribution Center),
  • the second is a client sending its logs to the server,
  • the third is receiver, gathering all logs.

1. KDC:

  • Kerberos database must be properly set-up on KDC machine first. Use kadmin/kadmin.local to do that. Two principals need to be add in our case:

  1. sender@REALM.ORG

  • client must have ticket for pricipal sender
  • REALM.ORG is kerberos Realm
  1. host/receiver.mydomain.com@REALM.ORG - service principal
  • Use ktadd to export service principal and transfer it to /etc/krb5.keytab on receiver

2. CLIENT:

  • set-up rsyslog, in /etc/rsyslog.conf
  • $ModLoad omgssapi - load output gss module
  • $GSSForwardServiceName otherThanHost - set the name of service principal, "host" is the default one
  • *.* :omgssapi:receiver.mydomain.com - action line, forward logs to receiver
  • kinit root - get the TGT ticket
  • service rsyslog start

3. SERVER:

  • set-up rsyslog, in /etc/rsyslog.conf

  • $ModLoad imgssapi - load input gss module

  • $InputGSSServerServiceName otherThanHost - set the name of service principal, "host" is the default one

  • $InputGSSServerPermitPlainTCP on - accept GSS and TCP connections (not authenticated senders), off by default

  • $InputGSSServerRun 514 - run server on port

  • service rsyslog start

The picture demonstrate how things work.

Compatibility Notes for rsyslog v7

This document describes things to keep in mind when moving from v6 to v7. It does not list enhancements nor does it talk about compatibility concerns introduced by earlier versions (for this, see their respective compatibility documents). Its focus is primarily on what you need to know if you used v6 and want to use v7 without hassle.

Version 7 builds on the new config language introduced in v6 and extends it. Other than v6, it not just only extends the config language, but provides considerable changes to core elements as well. The result is much more power and ease of use as well (this time that is not contradictionary).

BSD-Style blocks

BSD style blocks are no longer supported (for good reason). See the rsyslog BSD blocks info page for more information and how to upgrade your config.

[manual index] [rsyslog site]

CEE-Properties

In rsyslog v6, CEE properties could not be used across disk-based queues. If this was done, there content was reset. This was a missing feature in v6. In v7, this feature has been implemented. Consequently, situations where the previous behaviour were desired need now to be solved differently. We do not think that this will cause any problems to anyone, especially as in v6 this was announced as a missing feature.

omusrmsg: using just a username or "*" is deprecated

In legacy config format, the asterisk denotes writing the message to all users. This is usually used for emergency messages and configured like this: 

*.emerg  *

Unfortunately, the use of this single character conflicts with other uses, for example with the multiplication operator. While rsyslog up to versions v7.4 preserves the meaning of asterisk as an action, it is deprecated and will probably be removed in future versions. Consequently, a warning message is emitted. To make this warning go away, the action must be explicitly given, as follows: 

*.emerg  :omusrmsg:*

The same holds true for user names. For example 

*.emerg  john

at a minimum should be rewritten as 

*.emerg  :omusrmsg:john

Of course, for even more clarity the new RainerScript style of action can also be used: 

*.emerg  action(type="omusrmsg" users="john")

In Rainer's blog, there is more background information on why omusrmsg needed to be changed available.

omruleset and discard (~) action are deprecated

Both continue to work, but have been replaced by better alternatives.

The discard action (tilde character) has been replaced by the "stop" RainerScript directive. It is considered more intuitive and offers slightly better performance.

The omruleset module has been replaced by the "call" RainerScript directive. Call permits to execute a ruleset like a subroutine, and does so with much higher performance than omruleset did. Note that omruleset could be run off an async queue. This was more a side than a desired effect and is not supported by the call statement. If that effect was needed, it can simply be simulated by running the called rulesets actions asynchronously (what in any case is the right way to handle this).

Note that the deprecated modules emit warning messages when being used. They tell that the construct is deprecated and which statement is to be used as replacement. This does not affect operations: both modules are still fully operational and will not be removed in the v7 timeframe.

Retries of output plugins that do not do proper replies

Some output plugins may not be able to detect if their target is capable of accepting data again after an error (technically, they always return OK when TryResume is called). Previously, the rsyslog core engine suspended such an action after 1000 succesive failures. This lead to potentially a large amount of errors and error messages. Starting with 7.2.1, this has been reduced to 10 successive failures. This still gives the plugin a chance to recover. In extreme cases, a plugin may now enter suspend mode where it previously did not do so. In practice, we do NOT expect that.

Notes for the 7.3/7.4 branch

"last message repeated n times" Processing

This processing has been optimized and moved to the input side. This results in usually far better performance and also de-couples different sources from the same processing. It is now also integrated in to the more generic rate-limiting processing.

User-Noticable Changes

The code works almost as before, with two exceptions:
  • The supression amount can be different, as the new algorithm precisely check's a single source, and while that source is being read. The previous algorithm worked on a set of mixed messages from multiple sources.
  • The previous algorithm wrote a "last message repeated n times" message at least every 60 seconds. For performance reasons, we do no longer do this but write this message only when a new message arrives or rsyslog is shut down.

Note that the new algorithms needs support from input modules. If old modules which do not have the necessary support are used, duplicate messages will most probably not be detected. Upgrading the module code is simple, and all rsyslog-provided plugins support the new method, so this should not be a real problem (crafting a solution would result in rather complex code - for a case that most probably would never happen).

Performance Implications

In general, the new method enables far faster output procesing. However, it needs to be noted that the "last message repeated n" processing needs parsed messages in order to detect duplicated. Consequently, if it is enabled the parser step cannot be deferred to the main queue processing thread and thus must be done during input processing. The changes workload distribution and may have (good or bad) effect on the overall performance. If you have a very high performance installation, it is suggested to check the performance profile before deploying the new version. Note: for high-performance environments it is highly recommended NOT to use "last message repeated n times" processing but rather the other (more efficient) rate-limiting methods. These also do NOT require the parsing step to be done during input processing.

Stricter string-template Processing

Previously, no error message for invalid string template parameters was generated. Rather a malformed template was generated, and error information emitted at runtime. However, this could be quite confusing. Note that the new code changes user experience: formerly, rsyslog and the affected actions properly started up, but the actions did not produce proper data. Now, there are startup error messages and the actions are NOT executed (due to missing template due to template error).

The Property Replacer

The property replacer is a core component in rsyslogd's output system. A syslog message has a number of well-defined properties (see below). Each of this properties can be accessed and manipulated by the property replacer. With it, it is easy to use only part of a property value or manipulate the value, e.g. by converting all characters to lower case.

Accessing Properties

Syslog message properties are used inside templates. They are accessed by putting them between percent signs. Properties can be modified by the property replacer. The full syntax is as follows:

%propname:fromChar:toChar:options:fieldname%

Available Properties

propname is the name of the property to access. It is case-insensitive (prior to 3.17.0, they were case-senstive). Currently supported are:

msg the MSG part of the message (aka "the message" ;))
rawmsg the message excactly as it was received from the socket. Should be useful for debugging.
hostname hostname from the message
source alias for HOSTNAME
fromhost hostname of the system the message was received from (in a relay chain, this is the system immediately in front of us and not necessarily the original sender). This is a DNS-resolved name, except if that is not possible or DNS resolution has been disabled.
fromhost-ip The same as fromhost, but alsways as an IP address. Local inputs (like imklog) use 127.0.0.1 in this property.
syslogtag TAG from the message
programname the "static" part of the tag, as defined by BSD syslogd. For example, when TAG is "named[12345]", programname is "named".
pri PRI part of the message - undecoded (single value)
pri-text the PRI part of the message in textual form (e.g. "syslog.info")
iut the monitorware InfoUnitType - used when talking to a MonitorWare backend (also for phpLogCon)
syslogfacility the facility from the message - in numerical form
syslogfacility-text the facility from the message - in text form
syslogseverity severity from the message - in numerical form
syslogseverity-text severity from the message - in text form
syslogpriority an alias for syslogseverity - included for historical reasons (be careful: it still is the severity, not PRI!)
syslogpriority-text an alias for syslogseverity-text
timegenerated timestamp when the message was RECEIVED. Always in high resolution
timereported timestamp from the message. Resolution depends on what was provided in the message (in most cases, only seconds)
timestamp alias for timereported
protocol-version The contents of the PROTCOL-VERSION field from IETF draft draft-ietf-syslog-protcol
structured-data The contents of the STRUCTURED-DATA field from IETF draft draft-ietf-syslog-protocol
app-name The contents of the APP-NAME field from IETF draft draft-ietf-syslog-protocol
procid The contents of the PROCID field from IETF draft draft-ietf-syslog-protocol
msgid The contents of the MSGID field from IETF draft draft-ietf-syslog-protocol
parsesuccess This returns the status of the last called higher level parser, like mmjsonparse. A higher level parser parses the actual message for additional structured data and maintains an extra property table while doing so (this is often referred to as "cee data" because the idea was originally rooted in the cee effort, only (but has been extended since then). Note that higher level parsers must explicitely support (and set) this property. So, depending on the parser, it may not be set correctly.
If the parser properly supports it, the value "OK" means that parsing was successfull, while "FAIL" means the parser could not successfully obtain any data. Failure state is not necessarily an error. For example, it may simple indicate that the cee-enhanced syslog parser (mmjsonparse) did not detect cee-enhanced format, what can be totally valid. Using this property, further processing of the message can be directed based on this parsing outcome. If no parser has been called at the time this property is accessed, it will contain "FAIL".
This property is available since version 6.3.8.
inputname The name of the input module that generated the message (e.g. "imuxsock", "imudp"). Note that not all modules necessarily provide this property. If not provided, it is an empty string. Also note that the input module may provide any value of its liking. Most importantly, it is not necessarily the module input name. Internal sources can also provide inputnames. Currently, "rsyslogd" is defined as inputname for messages internally generated by rsyslogd, for example startup and shutdown and error messages. This property is considered useful when trying to filter messages based on where they originated - e.g. locally generated messages ("rsyslogd", "imuxsock", "imklog") should go to a different place than messages generated somewhere.
$bom The UTF-8 encoded Unicode byte-order mask (BOM). This may be useful in templates for RFC5424 support, when the character set is know to be Unicode.
$uptime system-uptime in seconds (as reported by operating system).
$now The current date stamp in the format YYYY-MM-DD
$year The current year (4-digit)
$month The current month (2-digit)
$day The current day of the month (2-digit)
$hour The current hour in military (24 hour) time (2-digit)
$hhour The current half hour we are in. From minute 0 to 29, this is always 0 while from 30 to 59 it is always 1.
$qhour The current quarter hour we are in. Much like $HHOUR, but values range from 0 to 3 (for the four quater hours that are in each hour)
$minute The current minute (2-digit)
$myhostname The name of the current host as it knows itself (probably useful for filtering in a generic way)
$!<name> This is the "bridge" to syslog message normalization (via mmnormalize): name is a name defined inside the normalization rule. It has the value selected by the rule or none if no rule with this field did match. You can also use these properties to specify JSON fields from the CEE-enhanced syslog message, once you parse it with mmjsonparse
$!all-json This is the JSON part of the CEE-enhanced syslog message, which can be parsed with mmjsonparse

Properties starting with a $-sign are so-called system properties. These do NOT stem from the message but are rather internally-generated.

Legacy Character Positions

FromChar and toChar are used to build substrings. They specify the offset within the string that should be copied. Offset counting starts at 1, so if you need to obtain the first 2 characters of the message text, you can use this syntax: "%msg:1:2%". If you do not whish to specify from and to, but you want to specify options, you still need to include the colons. For example, if you would like to convert the full message text to lower case, use "%msg:::lowercase%". If you would like to extract from a position until the end of the string, you can place a dollar-sign ("$") in toChar (e.g. %msg:10:$%, which will extract from position 10 to the end of the string).

There is also support for regular expressions. To use them, you need to place a "R" into FromChar. This tells rsyslog that a regular expression instead of position-based extraction is desired. The actual regular expression must then be provided in toChar. The regular expression must be followed by the string "--end". It denotes the end of the regular expression and will not become part of it. If you are using regular expressions, the property replacer will return the part of the property text that matches the regular expression. An example for a property replacer sequence with a regular expression is: "%msg:R:.*Sev:. \(.*\) \[.*--end%"

It is possible to specify some parametes after the "R". These are comma-separated. They are:

R,<regexp-type>,<submatch>,<nomatch>,<match-number>

regexp-type is either "BRE" for Posix basic regular expressions or "ERE" for extended ones. The string must be given in upper case. The default is "BRE" to be consistent with earlier versions of rsyslog that did not support ERE. The submatch identifies the submatch to be used with the result. A single digit is supported. Match 0 is the full match, while 1 to 9 are the acutal submatches. The match-number identifies which match to use, if the expression occurs more than once inside the string. Please note that the first match is number 0, the second 1 and so on. Up to 10 matches (up to number 9) are supported. Please note that it would be more natural to have the match-number in front of submatch, but this would break backward-compatibility. So the match-number must be specified after "nomatch".

nomatch specifies what should be used in case no match is found.

The following is a sample of an ERE expression that takes the first submatch from the message string and replaces the expression with the full field if no match is found:

%msg:R,ERE,1,FIELD:for (vlan[0-9]*):--end%

and this takes the first submatch of the second match of said expression:

%msg:R,ERE,1,FIELD,1:for (vlan[0-9]*):--end%

Please note: there is also a rsyslog regular expression checker/generator online tool available. With that tool, you can check your regular expressions and also generate a valid property replacer sequence. Usage of this tool is recommended. Depending on the version offered, the tool may not cover all subleties that can be done with the property replacer. It concentrates on the most often used cases. So it is still useful to hand-craft expressions for demanding environments.

Also, extraction can be done based on so-called "fields". To do so, place a "F" into FromChar. A field in its current definition is anything that is delimited by a delimiter character. The delimiter by default is TAB (US-ASCII value 9). However, if can be changed to any other US-ASCII character by specifying a comma and the decimal US-ASCII value of the delimiter immediately after the "F". For example, to use comma (",") as a delimiter, use this field specifier: "F,44".  If your syslog data is delimited, this is a quicker way to extract than via regular expressions (actually, a *much* quicker way). Field counting starts at 1. Field zero is accepted, but will always lead to a "field not found" error. The same happens if a field number higher than the number of fields in the property is requested. The field number must be placed in the "ToChar" parameter. An example where the 3rd field (delimited by TAB) from the msg property is extracted is as follows: "%msg:F:3%". The same example with semicolon as delimiter is "%msg:F,59:3%".

Please note that the special characters "F" and "R" are case-sensitive. Only upper case works, lower case will return an error. There are no white spaces permitted inside the sequence (that will lead to error messages and will NOT provide the intended result).

Each occurence of the field delimiter starts a new field. However, if you add a plus sign ("+") after the field delimiter, multiple delimiters, one immediately after the others, are treated as separate fields. This can be useful in cases where the syslog message contains such sequences. A frequent case may be with code that is written as follows:

int n, m;
...
syslog(LOG_ERR, "%d test %6d", n, m);

This will result into things like this in syslog messages: "1 test      2", "1 test     23", "1 test  234567"

As you can see, the fields are delimited by space characters, but their exact number is unknown. They can properly be extracted as follows:

"%msg:F,32:2%" to "%msg:F,32+:2%".

This feature was suggested by Zhuang Yuyao and implemented by him. It is modeled after perl compatible regular expressions.

Property Options

property options are case-insensitive. They are available as of version 6.5.0. Currently, the following options are defined:


This feature was introduced in rsyslog 4.6.2 and v4 versions above and 5.5.3 and all versions above.
Name New format. Name of the template / property / constant.
Outname This field permits to specify a field name for structured-data emitting property replacer options. It is most useful to set, for example, the name for JSON-based fields (like used in ommngodb). For text-based modules, it is simply ignored. If not specified, the original property name is used, with the exception of properties starting with "$!", where that prefix is removed. Note that unnamaned constants are NOT forwarded to output modules that expect structure (like ommnogodb). To pass constants, an outname must be set.
CaseConversion New format. Additional values below.
upper convert property to lowercase only
lower convert property text to uppercase only
DateFormat New format, additional parameter is needed. See below.
mysql format as mysql date
pgsql format as pgsql date
rfc3164 format as RFC 3164 date
rfc3164-buggyday similar to date-rfc3164, but emulates a common coding error: RFC 3164 demands that a space is written for single-digit days. With this option, a zero is written instead. This format seems to be used by syslog-ng and the date-rfc3164-buggyday option can be used in migration scenarios where otherwise lots of scripts would need to be adjusted. It is recommended not to use this option when forwarding to remote hosts - they may treat the date as invalid (especially when parsing strictly according to RFC 3164).
rfc3339 format as RFC 3339 date
unixtimestamp format as unix timestamp (seconds since epoch)
subseconds just the subseconds of a timestamp (always 0 for a low precision timestamp)
pos-end-relative the from and to position is relative to the end of the string instead of the usual start of string. (available since rsyslog v7.3.10)
ControlCharacters Option values for how to process control characters
escape replace control characters (ASCII value 127 and values less then 32) with an escape sequence. The sequnce is "#<charval>" where charval is the 3-digit decimal value of the control character. For example, a tabulator would be replaced by "#009".
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
space replace control characters by spaces
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
drop drop control characters - the resulting string will neither contain control characters, escape sequences nor any other replacement character like space.
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
SecurePath Option values for securing path templates.
drop Drops slashes inside the field (e.g. "a/b" becomes "ab"). Useful for secure pathname generation (with dynafiles).
replace Replace slashes inside the field by an underscore. (e.g. "a/b" becomes "a_b"). Useful for secure pathname generation (with dynafiles).
Format Option values for the general output format.
json encode the value so that it can be used inside a JSON field. This means that several characters (according to the JSON spec) are being escaped, for example US-ASCII LF is replaced by "\n". The json option cannot be used together with either jsonf or csv options.
jsonf (available in 6.3.9+) This signifies that the property should be expressed as a json field. That means not only the property is written, but rather a complete json field in the format
"fieldname"="value" where "filedname" is the assigend field name (or the property name if none was assigned) and value is the end result of property replacer operation. Note that value supports all property replacer options, like substrings, case converson and the like. Values are properly json-escaped. However, field names are (currently) not. It is expected that proper field names are configured. The jsonf option cannot be used together with either json or csv options.
csv formats the resulting field (after all modifications) in CSV format as specified in RFC 4180. Rsyslog will always use double quotes. Note that in order to have full CSV-formatted text, you need to define a proper template. An example is this one:
$template csvline,"%syslogtag:::csv%,%msg:::csv%"
Most importantly, you need to provide the commas between the fields inside the template. The csv option cannot be used together with either json or jsonf options.
This feature was introduced in rsyslog 4.1.6.
droplastlf The last LF in the message (if any), is dropped. Especially useful for PIX.
spifno1stsp This option looks scary and should probably not be used by a user. For any field given, it returns either a single space character or no character at all. Field content is never returned. A space is returned if (and only if) the first character of the field's content is NOT a space. This option is kind of a hack to solve a problem rooted in RFC 3164: 3164 specifies no delimiter between the syslog tag sequence and the actual message text. Almost all implementation in fact delemit the two by a space. As of RFC 3164, this space is part of the message text itself. This leads to a problem when building the message (e.g. when writing to disk or forwarding). Should a delimiting space be included if the message does not start with one? If not, the tag is immediately followed by another non-space character, which can lead some log parsers to misinterpret what is the tag and what the message. The problem finally surfaced when the klog module was restructured and the tag correctly written. It exists with other message sources, too. The solution was the introduction of this special property replacer option. Now, the default template can contain a conditional space, which exists only if the message does not start with one. While this does not solve all issues, it should work good enough in the far majority of all cases. If you read this text and have no idea of what it is talking about - relax: this is a good indication you will never need this option. Simply forget about it ;)
New character position In addition to the above mentioned Character Positions in the legacy format, positions can be determined by specifying the correct options for the properties. Again, this is mostly for using the list format.
position.From Character position in the property to start from.
position.To Character position that determines the end for extraction. If the value is "$" then the end of the string will be used.
field.Number The number of the field, which should be used for the search operation with Regex.
field.Delimiter The Character that should delimit a field. Example: ",". Everything in a property until this character is considered a field.
regex.Expression Value to be compared to property.
regex.Type Values BRE or ERE
regex.NoMatchMode DFLT, BLANK, ZERO, FIELD
regex.Match Match to use.
regex.Submatch Submatch to use. Values 0-9 whereas 0 = All

Legacy Property Options

property options are case-insensitive. Currently, the following options are defined:


This feature was introduced in rsyslog 4.6.2 and v4 versions above and 5.5.3 and all versions above.
uppercase convert property to lowercase only
lowercase convert property text to uppercase only
json encode the value so that it can be used inside a JSON field. This means that several characters (according to the JSON spec) are being escaped, for example US-ASCII LF is replaced by "\n". The json option cannot be used together with either jsonf or csv options.
jsonf (available in 6.3.9+) This signifies that the property should be expressed as a json field. That means not only the property is written, but rather a complete json field in the format
"fieldname"="value" where "filedname" is the assigend field name (or the property name if none was assigned) and value is the end result of property replacer operation. Note that value supports all property replacer options, like substrings, case converson and the like. Values are properly json-escaped. However, field names are (currently) not. It is expected that proper field names are configured. The jsonf option cannot be used together with either json or csv options.
csv formats the resulting field (after all modifications) in CSV format as specified in RFC 4180. Rsyslog will always use double quotes. Note that in order to have full CSV-formatted text, you need to define a proper template. An example is this one:
$template csvline,"%syslogtag:::csv%,%msg:::csv%"
Most importantly, you need to provide the commas between the fields inside the template. The csv option cannot be used together with either json or jsonf options.
This feature was introduced in rsyslog 4.1.6.
drop-last-lf The last LF in the message (if any), is dropped. Especially useful for PIX.
date-mysql format as mysql date
date-rfc3164 format as RFC 3164 date
date-rfc3164-buggyday similar to date-rfc3164, but emulates a common coding error: RFC 3164 demands that a space is written for single-digit days. With this option, a zero is written instead. This format seems to be used by syslog-ng and the date-rfc3164-buggyday option can be used in migration scenarios where otherwise lots of scripts would need to be adjusted.

date-rfc3339 format as RFC 3339 date
date-unixtimestamp format as unix timestamp (seconds since epoch)
date-subseconds just the subseconds of a timestamp (always 0 for a low precision timestamp)
escape-cc replace control characters (ASCII value 127 and values less then 32) with an escape sequence. The sequnce is "#<charval>" where charval is the 3-digit decimal value of the control character. For example, a tabulator would be replaced by "#009".
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
space-cc replace control characters by spaces
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
drop-cc drop control characters - the resulting string will neither contain control characters, escape sequences nor any other replacement character like space.
Note: using this option requires that $EscapeControlCharactersOnReceive is set to off.
sp-if-no-1st-sp This option looks scary and should probably not be used by a user. For any field given, it returns either a single space character or no character at all. Field content is never returned. A space is returned if (and only if) the first character of the field's content is NOT a space.

secpath-drop Drops slashes inside the field (e.g. "a/b" becomes "ab"). Useful for secure pathname generation (with dynafiles).
secpath-replace Replace slashes inside the field by an underscore. (e.g. "a/b" becomes "a_b"). Useful for secure pathname generation (with dynafiles).
mandatory-field In templates that are used for building field lists (in particular, ommongodb), include this field, even if it is empty (or NULL). If not set, the field will be removed from the output field set if empty. The latter is the default case.

To use multiple options, simply place them one after each other with a comma delmimiting them. For example "escape-cc,sp-if-no-1st-sp". If you use conflicting options together, the last one will override the previous one. For example, using "escape-cc,drop-cc" will use drop-cc and "drop-cc,escape-cc" will use escape-cc mode.

Fieldname

(available in 6.3.9+)

This field permits to specify a field name for structured-data emitting property replacer options. It was initially introduced to support the "jsonf" option, for which it provides the capability to set an alternative field name. If it is not specified, it defaults to the property name.

Generic Database Output Module (omlibdbi)

Module Name:    omlibdbi

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This modules supports a large number of database systems via libdbi. Libdbi abstracts the database layer and provides drivers for many systems. Drivers are available via the libdbi-drivers project. As of this writing, the following drivers are available:

The following drivers are in various stages of completion:

These drivers seem to be quite usable, at least from an rsyslog point of view.

Libdbi provides a slim layer between rsyslog and the actual database engine. We have not yet done any performance testing (e.g. omlibdbi vs. ommysql) but honestly believe that the performance impact should be irrelevant, if at all measurable. Part of that assumption is that rsyslog just does the "insert" and most of the time is spent either in the database engine or rsyslog itself. It's hard to think of any considerable time spent in the libdbi abstraction layer.

Setup

In order for this plugin to work, you need to have libdbi, the libdbi driver for your database backend and the client software for your database backend installed. There are libdbi packages for many distributions. Please note that rsyslogd requires a quite recent version (0.8.3) of libdbi. It may work with older versions, but these need some special ./configure options to support being called from a dlopen()ed plugin (as omlibdbi is). So in short, you probably save you a lot of headache if you make sure you have at least libdbi version 0.8.3 on your system.

Module Parameters

  • template
    The default template to use. This template is used when no template is explicitely specified in the action() statement.
  • driverdirectory
    Path to the libdbi drivers. Usually, you do not need to set it. If you installed libdbi-drivers at a non-standard location, you may need to specify the directory here. If you are unsure, do not use this configuration directive. Usually, everything works just fine. Note that this was an action() paramter in rsyslog versions below 7.3.0. However, only the first action's driverdirectory parameter was actually used. This has been cleaned up in 7.3.0, where this now is a module paramter.

Action Parameters

  • server
    Name or address of the MySQL server
  • db
    Database to use
  • uid
    logon userid used to connect to server. Must have proper permissions.
  • pwd
    the user's password
  • template
    Template to use when submitting messages.
  • driver
    Name of the dbidriver to use, see libdbi-drivers documentation. As a quick excerpt, at least those were available at the time of this writiting "mysql" (suggest to use ommysql instead), "firebird" (Firbird and InterBase), "ingres", "msql", "Oracle", "sqlite", "sqlite3", "freetds" (for Microsoft SQL and Sybase) and "pgsql" (suggest to use ompgsql instead).

Legacy (pre-v6) Configuration Directives:

It is strongly recommended NOT to use legacy format.

  • $ActionLibdbiDriverDirectory /path/to/dbd/drivers - like the driverdirectory action parameter.
  • $ActionLibdbiDriver drivername - like the drivername action parameter
  • $ActionLibdbiHost hostname - like the server action parameter
  • $ActionLibdbiUserName user - like the uid action parameter
  • $ActionlibdbiPassword - like the pwd action parameter
  • $ActionlibdbiDBName db - like the db action parameter
  • selector line: :omlibdbi:;template
    executes the recently configured omlibdbi action. The ;template part is optional. If no template is provided, a default template is used (which is currently optimized for MySQL - sorry, folks...)
Caveats/Known Bugs:

You must make sure that any templates used for omlibdbi properly escape strings. This is usually done by supplying the SQL (or STDSQL) option to the template. Omlibdbi rejects templates without this option for security reasons. However, omlibdbi does not detect if you used the right option for your backend. Future versions of rsyslog (with full expression  support) will provide advanced ways of handling this situation. So far, you must be careful. The default template provided by rsyslog is suitable for MySQL, but not necessarily for your database backend. Be careful!

If you receive the rsyslog error message "libdbi or libdbi drivers not present on this system" you may either not have libdbi and its drivers installed or (very probably) the version is earlier than 0.8.3. In this case, you need to make sure you have at least 0.8.3 and the libdbi driver for your database backend present on your system.

I do not have most of the database supported by omlibdbi in my lab. So it received limited cross-platform tests. If you run into troubles, be sure the let us know at http://www.rsyslog.com.

Sample:

The following sample writes all syslog messages to the database "syslog_db" on mysqlsever.example.com. The server is MySQL and being accessed under the account of "user" with password "pwd" (if you have empty passwords, just remove the $ActionLibdbiPassword line).

Legacy Sample:

The same as above, but in legacy config format (pre rsyslog-v6):

$DynaFileCacheSize

Type: global configuration directive

Default: 10

Description:

This directive specifies the maximum size of the cache for dynamically-generated file names. Selector lines with dynamic files names ('?' indicator) support writing to multiple files with a single selector line. This setting specifies how many open file handles should be cached. If, for example, the file name is generated with the hostname in it and you have 100 different hosts, a cache size of 100 would ensure that files are opened once and then stay open. This can be a great way to increase performance. If the cache size is lower than the number of different files, the least recently used one is discarded (and the file closed). The hardcoded maximum is 10,000 - a value that we assume should already be very extreme. Please note that if you expect to run with a very large number of files, you probably need to reconfigure the kernel to support such a large number. In practice, we do NOT recommend to use a cache of more than 1,000 entries. The cache lookup would probably require more time than the open and close operations. The minimum value is 1.

Numbers are always in decimal. Leading zeros should be avoided (in some later version, they may be mis-interpreted as being octal). Multiple directives may be given. They are applied to selector lines based on order of appearance.

Sample:

$DynaFileCacheSize 100    # a cache of 100 files at most

Encrypting Syslog Traffic with TLS (SSL)

Written by Rainer Gerhards (2008-06-17)

Sample Scenario

We have a quite simple scenario. There is one central syslog server, named central.example.net. These server is being reported to by two Linux machines with name zuse.example.net and turing.example.net. Also, there is a third client - ada.example.net - which send both its own messages to the central server but also forwards messages receive from an UDP-only capable router. We hav decided to use ada.example.net because it is in the same local network segment as the router and so we enjoy TLS' security benefits for forwarding the router messages inside the corporate network. All systems (except the router) use rsyslog as the syslog software.

Please note that the CA must not necessarily be connected to the rest of the network. Actually, it may be considered a security plus if it is not. If the CA is reachable via the regular network, it should be sufficiently secured (firewal rules et al). Keep in mind that if the CA's security is breached, your overall system security is breached.

In case the CA is compromised, you need to regenerate the CA's certificate as well as all individual machines certificates.

RSyslog - History

Rsyslog is a GPL-ed, enhanced syslogd. Among others, it offers support for reliable syslog over TCP, writing to MySQL databases and fully configurable output formats (including great timestamps). Rsyslog was initiated by Rainer Gerhards. If you are interested to learn why  Rainer initiated  the project, you may want to read his blog posting on "why the world needs another syslogd".

Rsyslog has been forked in 2004 from the sysklogd standard package. The goal of the rsyslog project is to provide a feature-richer and reliable syslog daemon while retaining drop-in replacement capabilities to stock syslogd. By "reliable", we mean support for reliable transmission modes like TCP or RFC 3195 (syslog-reliable). We do NOT imply that the sysklogd package is unreliable.

The name "rsyslog" stems back to the planned support for syslog-reliable. Ironically, the initial release of rsyslog did NEITHER support syslog-reliable NOR tcp based syslog. Instead, it contained enhanced configurability and other enhancements (like database support). The reason for this is that full support for RFC 3195 would require even more changes and especially fundamental architectural changes. Also, questions asked on the loganalysis list and at other places indicated that RFC3195 is NOT a prime priority for users, but rather better control over the output format. So there we were, with a rsyslogd that covers a lot of enhancements, but not a single one of these that made its name ;) Since version 0.9.2, receiving syslog messages via plain tcp is finally supported, a bit later sending via TCP, too. Starting with 1.11.0, RFC 3195 is finally supported at the receiving side (a.k.a. "listener"). Support for sending via RFC 3195 is still due. Anyhow, rsyslog has come much closer to what it name promises.

The database support was initially included so that our web-based syslog interface could be used. This is another open source project which can be found under http://www.phplogcon.org. We highly recommend having a look at it. It might not work for you if you expect thousands of messages per second (because your database won't be able to provide adequate performance), but in many cases it is a very handy analysis and troubleshooting tool. In the mean time, of course, lots of people have found many applications for writing to databases, so the prime focus is no longer on phpLogcon.

Rsyslogd supports an enhanced syslog.conf file format, and also works with the standard syslog.conf. In theory, it should be possible to simply replace the syslogd binary with the one that comes with rsyslog. Of course, in order to use any of the new features, you must re-write your syslog.conf. To learn how to do this, please review our commented sample.conf file. It outlines the enhancements over stock syslogd. Discussion has often arisen of whether having an "old syslogd" logfile format is good or evil. So far, this has not been solved (but Rainer likes the idea of a new format), so we need to live with it for the time being. It is planned to be reconsidered in the 3.x release time frame.

If you are interested in the IHE environment, you might be interested to hear that rsyslog supports message with sizes of 32k and more. This feature has been tested, but by default is turned off (as it has some memory footprint that we didn't want to put on users not actually requiring it). Search the file syslogd.c and search for "IHE" - you will find easy and precise instructions on what you need to change (it's just one line of code!). Please note that RFC 3195/COOKED supports 1K message sizes only. It'll probably support longer messages in the future, but it is our believe that using larger messages with current RFC 3195 is a violation of the standard.

In February 2007, 1.13.1 was released and served for quite a while as a stable reference. Unfortunately, it was not later released as stable, so the stable build became quite outdated.

In June 2007, Peter Vrabec from Red Hat helped us to create RPM files for Fedora as well as supporting IPv6. There also seemed to be some interest from the Red Hat community. This interest and new ideas resulted in a very busy time with many great additions.

In July 2007, Andrew Pantyukhin added BSD ports files for rsyslog and liblogging. We were strongly encouraged by this too. It looks like rsyslog is getting more and more momentum. Let's see what comes next...

Also in July 2007 (and beginning of August), Rainer remodeled the output part of rsyslog. It got a clean object model and is now prepared for a plug-in architecture. During that time, some base ideas for the overall new object model appeared.

In August 2007 community involvement grew more and more. Also, more packages appeared. We were quite happy about that. To facilitate user contributions, we set up a wiki on August 10th, 2007. Also in August 2007, rsyslog 1.18.2 appeared, which is deemed to be quite close to the final 2.0.0 release. With its appearance, the pace of changes was deliberately reduced, in order to allow it to mature (see Rainers's blog post on this topic, written a bit early, but covering the essence).

In November 2007, rsyslog became the default syslogd in Fedora 8. Obviously, that was something we *really* liked. Community involvement also is still growing. There is one sad thing to note: ever since summer, there is an extremely hard to find segfault bug. It happens on very rare occasions only and never in lab. We are hunting this bug for month now, but still could not get hold of it. Unfortunately, this also affects the new features schedule. It makes limited sense to implement new features if problems with existing ones are not really understood.

December 2007 showed the appearance of a postgres output module, contributed by sur5r. With 1.20.0, December is also the first time since the bug hunt that we introduce other new features. It has been decided that we carefully will add features in order to not affect the overall project by these rare bugs. Still, the bug hunt is top priority, but we need to have more data to analyze. At then end of December, it looked like the bug was found (a race condition), but further confirmation from the field is required before declaring victory. December also brings the initial development on rsyslog v3, resulting in loadable input modules, now running on a separate thread each.

On January, 2nd 2008, rsyslog 1.21.2 is re-released as rsyslog v2.0.0 stable. This is a major milestone as far as the stable build is concerned. v3 is not yet officially announced. Other than the stable v2 build, v3 will not be backwards compatibile (including missing compatibility to stock sysklogd) for quite a while. Config file changes are required and some command line options do no longer work due to the new design.

On January, 31st 2008 the new massively-multithreaded queue engine was released for the first time. It was a major milestone, implementing a feature I dreamed of for more than a year.

End of February 2008 saw the first note about RainerScript, a way to configure rsyslogd via a script-language like configuration format. This effort evolved out of the need to have complex expression support, which was also the first use case. On February, 28th rsyslog 3.12.0 was released, the first version to contain expression support. This also meant that rsyslog from that date on supported all syslog-ng major features, but had a number of major features exlusive to it. With 3.12.0, I consider rsyslog fully superior to syslog-ng (except for platform support).

Following the Fedora Developer's conference in Brno 2012, rsyslog got very serious on implementing structured logging in project Lumberjack (CEE) style. Project Lumberjack was a much broader effort and brought closer collaboration with the syslog-ng folks, which helped to maintain and improve interoperability. In the late winter/spring/summer 2012 timeframe numerous engine enhancements were made and plugins written (among them the first "official" interfaces to the Linux audit subsystem). At the end of the year, this culminated in the rsyslog 7, which not only implemented Lumberjack but also was the first one to support full condition nesting in rsyslog.conf (and a ton of other features as well).

In spring 2013 major new security features were engineered, namely anonymization support, as well as log file signing and encryption capabilities.

Be sure to visit Rainer's syslog blog to get some more insight into the development and futures of rsyslog and syslog in general. Don't be shy to post to either the blog or the rsyslog forums.

$FailOnChownFailure

Type: global configuration directive

Default: on

Description:

This option modifies behaviour of dynaFile creation. If different owners or groups are specified for new files or directories and rsyslogd fails to set these new owners or groups, it will log an error and NOT write to the file in question if that option is set to "on". If it is set to "off", the error will be ignored and processing continues. Keep in mind, that the files in this case may be (in)accessible by people who should not have permission. The default is "on".

Sample:

$FailOnChownFailure off

$DropTrailingLFOnReception

Type: global configuration directive

Default: on

Description:

Syslog messages frequently have the line feed character (LF) as the last character of the message. In almost all cases, this LF should not really become part of the message. However, recent IETF syslog standardization recommends against modifying syslog messages (e.g. to keep digital signatures valid). This option allows to specify if trailing LFs should be dropped or not. The default is to drop them, which is consistent with what sysklogd does.

Sample:

RELP Output Module (omrelp)

Module Name:    omrelp

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module supports sending syslog messages over the reliable RELP protocol. For RELP's advantages over plain tcp syslog, please see the documentation for imrelp (the server counterpart). 

Setup

Please note that librelp is required for imrelp (it provides the core relp protocol implementation).

Action Configuration Parameters:

This module supports RainerScript configuration starting with rsyslog 7.3.10. For older versions, legacy configuration directives must be used.

  • target (mandatory)
    The target server to connect to.
  • template (not mandatory, default "RSYSLOG_ForwardFormat")
    Defines the template to be used for the output.
  • timeout (not mandatory, default 90)
    Timeout for relp sessions. If set too low, valid sessions may be considered dead and tried to recover.

Sample:

The following sample sends all messages to the central server "centralserv" at port 2514 (note that that server must run imrelp on port 2514).

Legacy Configuration Directives:

This module uses old-style action configuration to keep consistent with the forwarding rule. So far, no additional configuration directives can be specified. To send a message via RELP, use

*.*  :omrelp:<sever>:<port>;<template>

just as you use 

*.*  @@<sever>:<port>;<template>

to forward a message via plain tcp syslog.

Caveats/Known Bugs:

See imrelp, which documents them. 

Legacy Sample:

The following sample sends all messages to the central server "centralserv" at port 2514 (note that that server must run imrelp on port 2514).

Note: to use IPv6 addresses, encode them in [::1] format.

$Escape8BitCharactersOnReceive

Type: global configuration directive

Default: off

Available Since: 5.5.2

Description:

This directive instructs rsyslogd to replace non US-ASCII characters (those that have the 8th bit set) during reception of the message. This may be useful for some systems. Please note that this escaping breaks Unicode and many other encodings. Most importantly, it can be assumed that Asian and European characters will be rendered hardly readable by this settings. However, it may still be useful when the logs themself are primarily in English and only occasionally contain local script. If this option is turned on, all control-characters are converted to a 3-digit octal number and be prefixed with the $ControlCharacterEscapePrefix character (being '#' by default).

Warning:

  • turning on this option most probably destroys non-western character sets (like Japanese, Chinese and Korean) as well as European character sets.
  • turning on this option destroys digital signatures if such exists inside the message
  • if turned on, the drop-cc, space-cc and escape-cc property replacer options do not work as expected because control characters are already removed upon message reception. If you intend to use these property replacer options, you must turn off $Escape8BitCharactersOnReceive.

Sample:

$Escape8BitCharactersOnReceive on

Output Channels

Output Channels are a new concept first introduced in rsyslog 0.9.0. As of this writing, it is most likely that they will be replaced by something different in the future. So if you use them, be prepared to change you configuration file syntax when you upgrade to a later release.

The idea behind output channel definitions is that it shall provide an umbrella for any type of output that the user might want. In essence,
this is the "file" part of selector lines (and this is why we are not sure output channel syntax will stay after the next review). There is a
difference, though: selector channels both have filter conditions (currently facility and severity) as well as the output destination. they can only be used to write to files - not pipes, ttys or whatever Output channels define the output definition, only. As of this build, else. If we stick with output channels, this will change over time.

In concept, an output channel includes everything needed to know about an output actions. In practice, the current implementation only carries
a filename, a maximum file size and a command to be issued when this file size is reached. More things might be present in future version, which might also change the syntax of the directive.

Output channels are defined via an $outchannel directive. It's syntax is as follows:

$outchannel name,file-name,max-size,action-on-max-size

name is the name of the output channel (not the file), file-name is the file name to be written to, max-size the maximum allowed size and action-on-max-size a command to be issued when the max size is reached. This command always has exactly one parameter. The binary is that part of action-on-max-size before the first space, its parameter is everything behind that space.

Please note that max-size is queried BEFORE writing the log message to the file. So be sure to set this limit reasonably low so that any message might fit. For the current release, setting it 1k lower than you expected is helpful. The max-size must always be specified in bytes - there are no special symbols (like 1k, 1m,...) at this point of development.

Keep in mind that $outchannel just defines a channel with "name". It does not activate it. To do so, you must use a selector line (see below). That selector line includes the channel name plus an $ sign in front of it. A sample might be:

*.* :omfile:$mychannel

In its current form, output channels primarily provide the ability to size-limit an output file. To do so, specify a maximum size. When this size is reached, rsyslogd will execute the action-on-max-size command and then reopen the file and retry. The command should be something like a log rotation script or a similar thing.

If there is no action-on-max-size command or the command did not resolve the situation, the file is closed and never reopened by rsyslogd (except, of course, by huping it). This logic was integrated when we first experienced severe issues with files larger 2gb, which could lead to rsyslogd dumping core. In such cases, it is more appropriate to stop writing to a single file. Meanwhile, rsyslogd has been fixed to support files larger 2gb, but obviously only on file systems and operating system versions that do so. So it can still make sense to enforce a 2gb file size limit.

Unix sockets Output Module (omuxsock)

Module Name:    omuxsock

Available since:    4.7.3, 5.5.7

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module supports sending syslog messages to local Unix sockets. Thus it provided a fast message-passing interface between different rsyslog instances. The counterpart to omuxsock is imuxsock. Note that the template used together with omuxsock must be suitable to be processed by the receiver.

Configuration Directives:

  • $OMUxSockSocket
    Name of the socket to send data to. This has no default and must be set.
  • $OMUxSockDefaultTemplate
    This can be used to override the default template to be used together with omuxsock. This is primarily useful if there are many forwarding actions and each of them should use the same template.
Caveats/Known Bugs:

Currently, only datagram sockets are supported.

Sample:

The following sample writes all messages to the "/tmp/socksample" socket.

Text File Input Module

Module Name:    imfile

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

Provides the ability to convert any standard text file into a syslog message. A standard text file is a file consisting of printable characters with lines being delimited by LF.

The file is read line-by-line and any line read is passed to rsyslog's rule engine. The rule engine applies filter conditions and selects which actions needs to be carried out. Empty lines are not processed, as they would result in empty syslog records. They are simply ignored.

As new lines are written they are taken from the file and processed. Please note that this happens based on a polling interval and not immediately. The file monitor support file rotation. To fully work, rsyslogd must run while the file is rotated. Then, any remaining lines from the old file are read and processed and when done with that, the new file is being processed from the beginning. If rsyslogd is stopped during rotation, the new file is read, but any not-yet-reported lines from the previous file can no longer be obtained.

When rsyslogd is stopped while monitoring a text file, it records the last processed location and continues to work from there upon restart. So no data is lost during a restart (except, as noted above, if the file is rotated just in this very moment).

Currently, the file must have a fixed name and location (directory). It is planned to add support for dynamically generating file names in the future.

Multiple files may be monitored by specifying $InputRunFileMonitor multiple times.

Configuration Directives:

Module Directives

  • PollingInterval seconds
    This is a global setting. It specifies how often files are to be polled for new data. The time specified is in seconds. The default value is 10 seconds. Please note that future releases of imfile may support per-file polling intervals, but currently this is not the case. If multiple PollingInterval statements are present in rsyslog.conf, only the last one is used.
    A short poll interval provides more rapid message forwarding, but requires more system resources. While it is possible, we stongly recommend not to set the polling interval to 0 seconds. That will make rsyslogd become a CPU hog, taking up considerable resources. It is supported, however, for the few very unusual situations where this level may be needed. Even if you need quick response, 1 seconds should be well enough. Please note that imfile keeps reading files as long as there is any data in them. So a "polling sleep" will only happen when nothing is left to be processed.

Action Directives

  • (required) File /path/to/file
    The file being monitored. So far, this must be an absolute name (no macros or templates)
  • (required) Tag tag:
    The tag to be used for messages that originate from this file. If you would like to see the colon after the tag, you need to specify it here (as shown above).
  • (required) StateFile <name-of-state-file>
    Rsyslog must keep track of which parts of the to be monitored file it already processed. This is done in the state file. This file always is created in the rsyslog working directory (configurable via $WorkDirectory). Be careful to use unique names for different files being monitored. If there are duplicates, all sorts of "interesting" things may happen. Rsyslog currently does not check if a name is specified multiple times. Note that when $WorkDirectory is not set or set to a non-writable location, the state file will not be generated.
  • Facility facility
    The syslog facility to be assigned to lines read. Can be specified in textual form (e.g. "local0", "local1", ...) or as numbers (e.g. 128 for "local0"). Textual form is suggested. Default  is "local0".
  • Severity
    The syslog severity to be assigned to lines read. Can be specified in textual form (e.g. "info", "warning", ...) or as numbers (e.g. 4 for "info"). Textual form is suggested. Default is "notice".
  • PersistStateInterval [lines]
    Specifies how often the state file shall be written when processing the input file. The default value is 0, which means a new state file is only written when the monitored files is being closed (end of rsyslogd execution). Any other value n means that the state file is written every time n file lines have been processed. This setting can be used to guard against message duplication due to fatal errors (like power fail). Note that this setting affects imfile performance, especially when set to a low value. Frequently writing the state file is very time consuming.
  • ReadMode [mode]
    This mode should defined when having multiline messages. The value can range from 0-2 and determines the multiline detection method.
    0 (default) - line based (Each line is a new message)
    1 - paragraph (There is a blank line between log messages)
    2 - indented (New log messages start at the beginning of a line. If a line starts with a space it is part of the log message before it)
  • MaxLinesAtOnce [number]
    This is useful if multiple files need to be monitored. If set to 0, each file will be fully processed and then processing switches to the next file (this was the default in previous versions). If it is set, a maximum of [number] lines is processed in sequence for each file, and then the file is switched. This provides a kind of mutiplexing the load of multiple files and probably leads to a more natural distribution of events when multiple busy files are monitored. The default is 1024.
  • MaxSubmitAtOnce [number]
    This is an expert option. It can be used to set the maximum input batch size that imfile can generate. The default is 1024, which is suitable for a wide range of applications. Be sure to understand rsyslog message batch processing before you modify this option. If you do not know what this doc here talks about, this is a good indication that you should NOT modify the default.
  • Ruleset <ruleset> Binds the listener to a specific ruleset.
Caveats/Known Bugs:

So far, only 100 files can be monitored. If more are needed, the source needs to be patched. See define MAX_INPUT_FILES in imfile.c

Powertop users may want to notice that imfile utilizes polling. Thus, it is no good citizen when it comes to conserving system power consumption. We are currently evaluating to move to inotify(). However, there are a number of subtle issues, which needs to be worked out first. We will make the change as soon as we can. If you can afford it, we recommend using a long polling interval in the mean time.

Sample:

The following sample monitors two files. If you need just one, remove the second one. If you need more, add them according to the sample ;). This code must be placed in /etc/rsyslog.conf (or wherever your distro puts rsyslog's config files). Note that only commands actually needed need to be specified. The second file uses less commands and uses defaults instead.

File Output Module

Module Name:    omfile

Author: Rainer Gerhards <rgergards@adiscon.com>

Description:

The omfile plug-in provides the core functionality of writing messages to files residing inside the local file system (which may actually be remote if methods like NFS are used). Both files named with static names as well files with names based on message content are supported by this module. It is a built-in module that does not need to be loaded.

 

Module Parameters:

  • Template [templateName]
    sets a new default template for file actions.

 

Action Parameters:

  • DynaFileCacheSize (not mandatory, default will be used)
    Defines a template to be used for the output.

  • ZipLevel 0..9 [default 0]
    if greater 0, turns on gzip compression of the output file. The higher the number, the better the compression, but also the more CPU is required for zipping.

  • VeryRobustZip [on/off] (v7.3.0+) - if ZipLevel is greater 0, then this setting controls if extra headers are written to make the resulting file extra hardened against malfunction. If set to off, data appended to previously unclean closed files may not be accessible without extra tools. Note that this risk is usually expected to be bearable, and thus "off" is the default mode. The extra headers considerably degrade compression, files with this option set to "on" may be four to five times as large as files processed in "off" mode.

  • FlushInterval (not mandatory, default will be used)
    Defines a template to be used for the output.

  • ASyncWriting on/off [default off]
    if turned on, the files will be written in asynchronous mode via a separate thread. In that case, double buffers will be used so that one buffer can be filled while the other buffer is being written. Note that in order to enable FlushInterval, AsyncWriting must be set to "on". Otherwise, the flush interval will be ignored. Also note that when FlushOnTXEnd is "on" but AsyncWriting is off, output will only be written when the buffer is full. This may take several hours, or even require a rsyslog shutdown. However, a buffer flush can be forced in that case by sending rsyslogd a HUP signal.

  • FlushOnTXEnd on/off [default on]
    Omfile has the capability to write output using a buffered writer. Disk writes are only done when the buffer is full. So if an error happens during that write, data is potentially lost. In cases where this is unacceptable, set FlushOnTXEnd to on. Then, data is written at the end of each transaction (for pre-v5 this means after each log message) and the usual error recovery thus can handle write errors without data loss. Note that this option severely reduces the effect of zip compression and should be switched to off for that use case. Note that the default -on- is primarily an aid to preserve the traditional syslogd behaviour.

  • IOBufferSize <size_nbr>, default 4k
    size of the buffer used to writing output data. The larger the buffer, the potentially better performance is. The default of 4k is quite conservative, it is useful to go up to 64k, and 128K if you used gzip compression (then, even higher sizes may make sense)

  • DirOwner
    Set the file owner for directories newly created. Please note that this setting does not affect the owner of directories already existing. The parameter is a user name, for which the userid is obtained by rsyslogd during startup processing. Interim changes to the user mapping are not detected.

  • DirGroup
    Set the group for directories newly created. Please note that this setting does not affect the group of directories already existing. The parameter is a group name, for which the groupid is obtained by rsyslogd on during startup processing. Interim changes to the user mapping are not detected.

  • FileOwner
    Set the file owner for files newly created. Please note that this setting does not affect the owner of files already existing. The parameter is a user name, for which the userid is obtained by rsyslogd during startup processing. Interim changes to the user mapping are not detected.

  • FileGroup
    Set the group for files newly created. Please note that this setting does not affect the group of files already existing. The parameter is a group name, for which the groupid is obtained by rsyslogd during startup processing. Interim changes to the user mapping are not detected.

  • DirCreateMode [defaul 0700]
    This is the same as $FileCreateMode, but for directories automatically generated.

  • FileCreateMode [default 0644]
    The FileCreateMode directive allows to specify the creation mode with which rsyslogd creates new files. If not specified, the value 0644 is used (which retains backward-compatibility with earlier releases). The value given must always be a 4-digit octal number, with the initial digit being zero.
    Please note that the actual permission depend on rsyslogd's process umask. If in doubt, use "$umask 0000" right at the beginning of the configuration file to remove any restrictions.
    FileCreateMode may be specified multiple times. If so, it specifies the creation mode for all selector lines that follow until the next $FileCreateMode directive. Order of lines is vitally important.

  • FailOnCHOwnFailure on/off [default on]
    This option modifies behaviour of file creation. If different owners or groups are specified for new files or directories and rsyslogd fails to set these new owners or groups, it will log an error and NOT write to the file in question if that option is set to "on". If it is set to "off", the error will be ignored and processing continues. Keep in mind, that the files in this case may be (in)accessible by people who should not have permission. The default is "on".

  • CreateDirs on/off [default on]
    create directories on an as-needed basis

  • Sync on/off [default off]
    enables file syncing capability of omfile.

  • File
    If the file already exists, new data is appended to it. Existing data is not truncated. If the file does not already exist, it is created. Files are kept open as long as rsyslogd is active. This conflicts with external log file rotation. In order to close a file after rotation, send rsyslogd a HUP signal after the file has been rotated away.

  • DynaFile
    For each message, the file name is generated based on the given template. Then, this file is opened. As with the ``file'' property, data is appended if the file already exists. If the file does not exist, a new file is created. A cache of recent files is kept. Note that this cache can consume quite some memory (especially if large buffer sizes are used). Files are kept open as long as they stay inside the cache. Currently, files are only evicted from the cache when there is need to do so (due to insufficient cache size). To force-close (and evict) a dynafile from cache, send a HUP signal to rsyslogd.

  • Sig.Provider [ProviderName]
    Selects a signature provider for log signing. Currently, there only is one provider called "gt".

  • Cry.Provider [ProviderName]
    Selects a crypto provider for log encryption. Currently, there only is one provider called "gcry".

  • Template [templateName]
    sets a new default template for file actions.

Caveats/Known Bugs:

  • One needs to be careful with log rotation if signatures and/or encryption are being used. These create side-files, which form a set and must be kept together.
    For signatures, the ".sigstate" file must NOT be rotated away if signature chains are to be build across multiple files. This is because .sigstate contains just global information for the whole file set. However, all other files need to be rotated together. The proper sequence is to
    1. move all files inside the file set
    2. only AFTER this is completely done, HUP rsyslog
    This sequence will ensure that all files inside the set are atomically closed and in sync. HUPing only after a subset of files have been moved results in inconsistencies and will most probably render the file set unusable.

Sample:

The following command writes all syslog messages into a file.

Program integration Output module

Module Name:    omprog

Available since:    4.3.0

Author: Rainer Gerhards <rgerhards@adiscon.com>

Description:

This module permits to integrate arbitrary external programs into rsyslog's logging. It is similar to the "execute program (^)" action, but offers better security and much higher performance. While "execute program (^)" can be a useful tool for executing programs if rare events occur, omprog can be used to provide massive amounts of log data to a program.

Executes the configured program and feeds log messages to that binary via stdin. The binary is free to do whatever it wants with the supplied data. If the program terminates, it is re-started. If rsyslog terminates, the program's stdin will see EOF. The program must than terminate. The message format passed to the program can, as usual, be modified by defining rsyslog templates.

Note that each time an omprog action is defined, the corresponding programm is invoked. A single instance is not being re-used. There are arguments pro and con re-using existing binaries. For the time being, it simply is not done. In the future, we may add an option for such pooling, provided that some demand for that is voiced. You can also mimic the same effect by defining multiple rulesets and including them (at the price of some slight performance loss).

Configuration Directives:

  • $ActionOMProgBinary <binary>
    The binary program to be executed.
Caveats/Known Bugs:

Currently none known.

Modules

Rsyslog has a modular design. This enables functionality to be dynamically loaded from modules, which may also be written by any third party. Rsyslog itself offers all non-core functionality as modules. Consequently, there is a growing number of modules. Here is the entry point to their documentation and what they do (list is currently not complete)

Please note that each module provides configuration directives, which are NOT necessarily being listed below. Also remember, that a modules configuration directive (and functionality) is only available if it has been loaded (using $ModLoad).

It is relatively easy to write a rsyslog module. If none of the provided modules solve your need, you may consider writing one or have one written for you by Adiscon's professional services for rsyslog (this often is a very cost-effective and efficient way of getting what you need).

There exist different classes of loadable modules:

Input Modules

Input modules are used to gather messages from various sources. They interface to message generators.

  • imfile -  input module for text files
  • imrelp - RELP input module
  • imudp - udp syslog message input
  • imtcp - input plugin for tcp syslog
  • imptcp - input plugin for plain tcp syslog (no TLS but faster)
  • imgssapi - input plugin for plain tcp and GSS-enabled syslog
  • immark - support for mark messages
  • imklog - kernel logging
  • imuxsock - unix sockets, including the system log socket
  • imsolaris - input for the Sun Solaris system log source
  • im3195 - accepts syslog messages via RFC 3195
  • impstats - provides periodic statistics of rsyslog internal counters
  • imjournal - Linux journal inuput module

Output Modules

Output modules process messages. With them, message formats can be transformed and messages be transmitted to various different targets.

  • omfile - file output module
  • omfwd - syslog forwarding output module
  • omjournal - Linux journal output module
  • ompipe - named pipe output module
  • omusrmsg - user message output module
  • omsnmp - SNMP trap output module
  • omtdout - stdout output module (mainly a test tool)
  • omrelp - RELP output module
  • omruleset - forward message to another ruleset
  • omgssapi - output module for GSS-enabled syslog
  • ommysql - output module for MySQL
  • ompgsql - output module for PostgreSQL
  • omlibdbi - generic database output module (Firebird/Interbase, MS SQL, Sybase, SQLLite, Ingres, Oracle, mSQL)
  • ommail - permits rsyslog to alert folks by mail if something important happens
  • omprog - permits sending messages to a program for custom processing
  • omoracle - output module for Oracle (native OCI interface)
  • omudpspoof - output module sending UDP syslog messages with a spoofed address
  • omuxsock - output module Unix domain sockets
  • omhdfs - output module for Hadoop's HDFS file system
  • ommongodb - output module for MongoDB
  • omelasticsearch - output module for ElasticSearch

Parser Modules

Parser modules are used to parse message content, once the message has been received. They can be used to process custom message formats or invalidly formatted messages. For details, please see the rsyslog message parser documentation.

The current modules are currently provided as part of rsyslog:

  • pmrfc5424[builtin] - rsyslog.rfc5424 - parses RFC5424-formatted messages (the new syslog standard)
  • pmrfc3164[builtin] - rsyslog.rfc3164 - the traditional/legacy syslog parser
  • pmrfc3164sd - rsyslog.rfc3164sd - a contributed module supporting RFC5424 structured data inside RFC3164 messages (not supported by the rsyslog team)
  • pmlastmsg - rsyslog.lastmsg - a parser module that handles the typically malformed "last messages repated n times" messages emitted by some syslogds.

Message Modification Modules

Message modification modules are used to change the content of messages being processed. They can be implemented using either the output module or the parser module interface. From the rsyslog core's point of view, they actually are output or parser modules, it is their implementation that makes them special.

Currently, there exists only a limited set of such modules, but new ones could be written with the methods the engine provides. They could be used, for example, to add dynamically computed content to message (fields).

Message modification modules are usually written for one specific task and thus usually are not generic enough to be reused. However, existing module's code is probably an excellent starting base for writing a new module. Currently, the following modules exist inside the source tree:

  • mmanon - used to anonymize log messages.
  • mmnormalize - used to normalize log messages. Note that this actually is a generic module.
  • mmjsonparse - used to interpret CEE/lumberjack enabled structured log messages.
  • mmsnmptrapd - uses information provided by snmptrapd inside the tag to correct the original sender system and priority of messages. Implemented via the output module interface.

String Generator Modules

String generator modules are used, as the name implies, to generate strings based on the message content. They are currently tightly coupled with the template system. Their primary use is to speed up template processing by providing a native C interface to template generation. These modules exist since 5.5.6. To get an idea of the potential speedup, the default file format, when generated by a string generator, provides a roughly 5% speedup. For more complex strings, especially those that include multiple regular expressions, the speedup may be considerably higher.

String generator modules are written to a quite simple interface. However, a word of caution is due: they access the rsyslog message object via a low-level interface. That interface is not guaranteed yet to stay stable. So it may be necessary to modify string generator modules if the interface changes. Obviously, we will not do that without good reason, but it may happen.

Rsyslog comes with a set of core, build-in string generators, which are used to provide those default templates that we consider to be time-critical:

  • smfile - the default rsyslog file format
  • smfwd - the default rsyslog (network) forwarding format
  • smtradfile - the traditional syslog file format
  • smfwd - the traditional syslog (network) forwarding format

Note that when you replace these defaults be some custom strings, you will loose some performance (around 5%). For typical systems, this is not really relevant. But for a high-performance systems, it may be very relevant. To solve that issue, create a new string generator module for your custom format, starting out from one of the default generators provided. If you can not do this yourself, you may want to contact Adiscon as we offer custom development of string generators at a very low price.

Note that string generator modules can be dynamically loaded. However, the default ones provided are so important that they are build right into the executable. But this does not need to be done that way (and it is straightforward to do it dynamic).

Library Modules

Library modules provide dynamically loadable functionality for parts of rsyslog, most often for other loadable modules. They can not be user-configured and are loaded automatically by some components. They are just mentioned so that error messages that point to library moduls can be understood. No module list is provided.

Where are the modules integrated into the Message Flow?

Depending on their module type, modules may access and/or modify messages at various stages during rsyslog's processing. Note that only the "core type" (e.g. input, output) but not any type derived from it (message modification module) specifies when a module is called.

The simplified workflow is as follows:

As can be seen, messages are received by input modules, then passed to one or many parser modules, which generate the in-memory representation of the message and may also modify the message itself. The, the internal representation is passed to output modules, which may output a message and (with the interfaces newly introduced in v5) may also modify messageo object content.

String generator modules are not included inside this picture, because they are not a required part of the workflow. If used, they operate "in front of" the output modules, because they are called during template generation.

Note that the actual flow is much more complex and depends a lot on queue and filter settings. This graphic above is a high-level message flow diagram.

Message parsers in rsyslog

Written by Rainer Gerhards (2009-11-06)

Intro

Message parsers are a feature of rsyslog 5.3.4 and above. In this article, I describe what message parsers are, what they can do and how they relate to the relevant standards. I will also describe what you can not do with time. Finally, I give some advice on implementing your own custom parser.

What are message parsers?

Well, the quick answer is that message parsers are the component of rsyslog that parses the syslog message after it is being received. Prior to rsyslog 5.3.4, message parsers where built in into the rsyslog core itself and could not be modified (other than by modifying the rsyslog code).

In 5.3.4, we changed that: message parsers are now loadable modules (just like input and output modules). That means that new message parsers can be added without modifying the rsyslog core, even without contributing something back to the project.

But that doesn't answer what a message parser really is. What does ist mean to "parse a message" and, maybe more importantly, what is a message? To answer these questions correctly, we need to dig down into the relevant standards. RFC5424 specifies a layered architecture for the syslog protocol:

RFC5424 syslog protocol layers

For us important is the distinction between the syslog transport and the upper layers. The transport layer specifies how a stream of messages is assembled at the sender side and how this stream of messages is disassembled into the individual messages at the receiver side. In networking terminology, this is called "framing". The core idea is that each message is put into a so-called "frame", which then is transmitted over the communications link.

The framing used is depending on the protocol. For example, in UDP the "frame"-equivalent is a packet that is being sent (this also means that no two messages can travel within a single UDP packet). In "plain tcp syslog", the industry standard, LF is used as a frame delimiter (which also means that no multi-line message can properly be transmitted, a "design" flaw in plain tcp syslog). In RFC5425 there is a header in front of each frame that contains the size of the message. With this framing, any message content can properly be transferred.

And now comes the important part: message parsers do NOT operate at the transport layer, they operate, as their name implies, on messages. So we can not use message parsers to change the underlying framing. For example, if a sender splits (for whatever reason) a single message into two and encapsulates these into two frames, there is no way a message parser could undo that.

A typical example may be a multi-line message: let's assume some originator has generated a message for the format "A\nB" (where \n means LF). If that message is being transmitted via plain tcp syslog, the frame delimiter is LF. So the sender will delimite the frame with LF, but otherwise send the message unmodified onto the wire (because that is how things are -unfortunately- done in plain tcp syslog...). So wire will see "A\nB\n". When this arrives at the receiver, the transport layer will undo the framing. When it sees the LF after A, it thinks it finds a valid frame delimiter (in fact, this is the correct view!). So the receive will extract one complete message A and one complete message B, not knowing that they once were both part of a large multi-line message. These two messages are then passed to the upper layers, where the message parsers receive them and extract information. However, the message parsers never know (or even have a chance to see) that A and B belonged together. Even further, in rsyslog there is no guarnatee that A will be parsed before B - concurrent operations may cause the reverse order (and do so very validly).

The important lesson is: message parsers can not be used to fix a broken framing. You need a full protocol implementation to do that, what is the domain of input and output modules.

I have now told you what you can not do with message parsers. But what they are good for? Thankfully, broken framing is not the primary problem of the syslog world. A wealth of different formats is. Unfortunately, many real-world implementations violate the relevant standards in one way or another. That makes it often very hard to extract meaningful information from a message or to process messages from different sources by the same rules. In my article syslog parsing in rsyslog I have elaborated on all the real-world evil that you can usually see. So I won't repeat that here. But in short, the real problem is not the framing, but how to make malformed messages well-looking.

This is what message parsers permit you to do: take a (well-known) malformed message, parse it according to its semantics and generate perfectly valid internal message representations from it. So as long as messages are consistenly in the same wrong format (and they usually are!), a message parser can look at that format, parse it, and make the message processable just like it were wellformed in the first place. Plus, one can abuse the interface to do some other "intersting" tricks, but that would take us to far.

While this functionality may not sound exciting, it actually solves a very big issue (that you only really understand if you have managed a system with various different syslog sources). Note that we were often able to process malformed messages in the past with the help of the property replacer and regular expressions. While this is nice, it has a performance hit. A message parser is a C code, compiled to native language, and thus typically much faster than any regular expression based method (depending, of course, on the quality of the implementation...).

How are message parsers used?

In a simlified view, rsyslog

  1. first receives messages (via the input module),
  2. then parses them (at the message level!) and
  3. then processes them (operating on the internal message representation).
Message parsers are utilized in the second step (written in italics). Thus, they take the raw message (NOT frame!) received from the remote system and create the internal structure out of it that the other parts of rsyslog need in order to perform their processing. Parsing is vital, because an unparsed message can not be processed in the third stage, the actual application-level processing (like forwarding or writing to files).

Parser Chains and how they Operate

Rsyslog chains parsers together to provide flexibility. A parser chain contains all parsers that can potentially be used to parse a message. It is assumed that there is some way a parser can detect if the message it is being presented is supported by it. If so, the parser will tell the rsyslog engine and parse the message. The rsyslog engine now calls each parser inside the chain (in sequence!) until the first parser is able to parse the message. After one parser has been found, the message is considered parsed and no others parsers are called on that message.

Side-note: this method implies there are some "not-so-dirty" tricks available to modify the message by a parser module that declares itself as "unable to parse" but still does some message modification. This was not a primary design goal, but may be utilized, and the interface probably extended, to support generic filter modules. These would need to go to the root of the parser chain. As mentioned, the current system already supports this.

The position inside the parser chain can be thought of as a priority: parser sitting earlier in the chain take precedence over those sitting later in it. So more specific parser should go ealier in the chain. A good example of how this works is the default parser set provided by rsyslog: rsyslog.rfc5424 and rsyslog.rfc3164, each one parses according to the rfc that has named it. RFC5424 was designed to be distinguishable from RFC3164 message by the sequence "1 " immediately after the so-called PRI-part (don't worry about these words, it is sufficient if you understand there is a well-defined sequence used to indentify RFC5424 messages). In contrary, RFC3164 actually permits everything as a valid message. Thus the RFC3164 parser will always parse a message, sometimes with quite unexpected outcome (there is a lot of guesswork involved in that parser, which unfortunately is unavoidable due to existing techology limits). So the default parser chain is to try the RFC5424 parser first and after it the RFC3164 parser. If we have a 5424-formatted message, that parser will identify and parse it and the rsyslog engine will stop processing. But if we receive a legacy syslog message, the RFC5424 will detect that it can not parse it, return this status to the engine which then calls the next parser inside the chain. That usually happens to be the RFC3164 parser, which will always process the message. But there could also be any other parser inside the chain, and then each one would be called unless one that is able to parse can be found.

If we reversed the parser order, RFC5424 messages would incorrectly parsed. Why? Because the RFC3164 parser will always parse every message, so if it were asked first, it would parse (and misinterpret) the 5424-formatted message, return it did so and the rsyslog engine would never call the 5424 parser. So oder of sequence is very important.

What happens if no parser in the chain could parse a message? Well, then we could not obtain the in-memory representation that is needed to further process the message. In that case, rsyslog has no other choice than to discard the message. If it does so, it will emit a warning message, but only in the first 1,000 incidents. This limit is a safety measure against message-loops, which otherwise could quickly result from a parser chain misconfiguration. If you do not tolerate loss of unparsable messages, you must ensure that each message can be parsed. You can easily achive this by always using the "rsyslog-rfc3164" parser as the last parser inside parser chains. That may result in invalid parsing, but you will have a chance to see the invalid message (in debug mode, a warning message will be written to the debug log each time a message is dropped due to inability to parse it).

Where are parser chains used?

We now know what parser chains are and how they operate. The question is now how many parser chains can be active and how it is decicded which parser chain is used on which message. This is controlled via rsyslog's rulesets. In short, multiple rulesets can be defined and there always exist at least one ruleset (for specifcs, follow the link). A parser chain is bound to a specific ruleset. This is done by virtue of defining parsers via the $RulesetParser configuration directive (for specifics, see there). If no such directive is specified, the default parser chain is used. As of this writing, the default parser chain always consists of "rsyslog.rfc5424", "rsyslog.rfc3164", in that order. As soon as a parser is configured, the default list is cleared and the new parser is added to the end of the (initially empty) ruleset's parser chain.

The important point to know is that parser chains are defined on a per-ruleset basis.

Can I use different parser chains for different devices?

The correct answer is: generally yes, but it depends. First of all, remember that input modules (and specific listeners) may be bound to specific rulesets. As parser chains "reside" in rulesets, binding to a ruleset also binds to the parser chain that is bound to that ruleset. As a number one prequisite, the input module must support binding to different rulesets. Not all do, but their number is growing. For example, the important imudp and imtcp input modules support that functionality. Those that do not (for example im3195) can only utilize the default ruleset and thus the parser chain defined in that ruleset.

If you do not know if the input module in question supports ruleset binding, check its documentation page. Those that support it have the requiered directives.

Note that it is currently under evaluation if rsyslog will support binding parser chains to specific inputs directly, without depending on the ruleset. There are some concerns that this may not be necessary but adds considerable complexity to the configuration. So this may or may not be possible in the future. In any case, if we decide to add it, input modules need to support it, so this functionality would require some time to implement.

The coockbook recipe for using different parsers for different devices is given as an actual in-depth example in the $RulesetParser configuration directive doc page. In short, it is acomplished by defining specific rulesets for the required parser chains, definining different listener ports for each of the devices with different format and binding these listeners to the correct ruleset (and thus parser chains). Using that approach, a variety of different message formats can be supported via a single rsyslog instance.

Which message parsers are available

As of this writing, there exist only two message parsers, one for RFC5424 format and one for legacy syslog (loosely described in RFC3164). These parsers are built-in and must not be explicitely loaded. However, message parsers can be added with relative ease by anyone knowing to code in C. Then, they can be loaded via $ModLoad just like any other loadable module. It is expected that the rsyslog project will be contributed additional message parsers over time, so that at some point there hopefully is a rich choice of them (I intend to add a browsable repository as soon as new parsers pop up).

How to write a message parser?

As a prequisite, you need to know the exact format that the device is sending. Then, you need moderate C coding skills, and a little bit of rsyslog internals. I guess the rsyslog specific part should not be that hard, as almost all information can be gained from the existing parsers. They are rather simple in structure and can be found under the "./tools" directory. They are named pmrfc3164.c and pmrfc5424.c. You need to follow the usual loadable module guidelines. It is my expectation that writing a parser should typically not take longer than a single day, with maybe a day more to get aquainted with rsyslog. Of course, I am not sure if the number is actually right.

If you can not program or have no time to do it, Adiscon can also write a message parser for you as part of the rsyslog professional services offering.

Conclusion

Malformed syslog messages are a pain and unfortunately often seen in practice. Message parsers provide a fast and efficient solution for this problem. Different parsers can be defined for different devices, and they all convert message information into rsyslog's well-defined internal format. Message parsers were first introduced in rsyslog 5.3.4 and also offer some interesting ideas that may be explored in the future - up to full message normalization capabilities. It is strongly recommended that anyone with a heterogenous environment take a look at message parser capabilities.

$MaxOpenFiles

Available Since: 4.3.0

Type: global configuration directive

Default: operating system default

Description:

Set the maximum number of files that the rsyslog process can have open at any given time. Note that this includes open tcp sockets, so this setting is the upper limit for the number of open TCP connections as well. If you expect a large nubmer of concurrent connections, it is suggested that the number is set to the max number connected plus 1000. Please note that each dynafile also requires up to 100 open file handles.

The setting is similar to running "ulimit -n number-of-files".

Please note that depending on permissions and operating system configuration, the setrlimit() request issued by rsyslog may fail, in which case the previous limit is kept in effect. Rsyslog will emit a warning message in this case.

Sample:

$MaxOpenFiles 2000

Bugs:

For some reason, this settings seems not to work on all platforms. If you experience problems, please let us know so that we can (hopefully) narrow down the issue.

syslog parsing in rsyslog

Written by Rainer Gerhards (2008-09-23)

We regularly receive messages asking why rsyslog parses this or that message incorrectly. Of course, it turns out that rsyslog does the right thing, but the message sender does not. And also of course, this is not even of the slightest help to the end user experiencing the problem ;). So I thought I write this paper. It describes the problem source and shows potential solutions (aha!).

Syslog Standardization

The syslog protocol has not been standardized until relatively recently.The first document "smelling" a bit like a standard is RFC 3164, which dates back to August 2001. The problem is that this document is no real standard. It has assigned "informational" status by the IETF which means it provides some hopefully useful information but does not demand anything. It is impossible to "comply" to an informational document. This, of course, doesn't stop marketing guys from telling they comply to RFC3164 and it also does not stop some techs to tell you "this and that does not comply to RFC3164, so it is <anybody else but them>'s fault".

Then, there is RFC3195, which is a real standard. In it's section 3 it makes (a somewhat questionable) reference to (informational) RFC 3164 which may be interpreted in a way that RFC3195 standardizes the format layed out in RFC 3164 by virtue of referencing them. So RFC3195 seems to extend its standardization domain to the concepts layed out in RFC 3164 (which is why I tend to find that refrence questionable). In that sense, RFC3195 standardizes the format informationally described in RFC3164, Section 4. But it demands it only for the scope of RFC3195, which is syslog over BEEP - and NOT syslog over UDP. So one may argue whether or not the RFC3164 format could be considered a standard for any non-BEEP (including UDP) syslog, too. In the strict view I tend to have, it does not. Refering to the RFC3195 context usually does not help, because there are virtually no RFC3195 implementations available (at this time, I would consider this RFC a failure).

Now let's for a short moment assume that RFC3195 would somehow be able to demand RFC3164 format for non-BEEP syslog. So we could use RFC3164 format as a standard. But does that really help? Let's cite RFC 3164, right at the begining of section 4 (actually, this is the first sentence): 

   The payload of any IP packet that has a UDP destination port of 514
   MUST be treated as a syslog message. 



Think a bit about it: this means that whatever is send to port 514 must be considered
a valid syslog message. No format at all is demanded. So if "this is junk" is sent to
UDP port 514 - voila, we have a valid message (interestingly, it is no longer a syslog
message if it is sent to port 515 ;)). You may now argue that I am overdoing. So let's
cite RFC 3164, Section 5.4, Example 2:



  Example 2

        Use the BFG!

   While this is a valid message, it has extraordinarily little useful
   information.





As you can see, RFC3164 explicitely states that no format at all is required.

Now a side-note is due: all of this does not mean that the RFC3164 authors
did not know what they were doing. No, right the contrary is true: RFC3164 mission
is to describe what has been seen in practice as syslog messages and the 
conclusion is quite right that there is no common understanding on the
message format. This is also the reason why RFC3164 is an informational document:
it provides useful information, but does not precisely specify anything.

After all of this bashing, I now have to admit that RFC3164 has some format
recommendations layed out in section 4. The format described has quite some
value in it and implementors recently try to follow it. This format is usually meant
when someone tells you that a software is "RFC3164 compliant" or expects "RFC3164 compliant messages".
I also have to admit that rsyslog also uses this format and, in the sense outlined here,
expects messages received to be "RFC3164 compliant" (knowingly that such a beast does not
exist - I am simply lying here ;)).

Please note that there is some relief of the situation in reach. There is a new normative
syslog RFC series upcoming, and it specifies a standard message format. At the time of
this writing, the main documents are sitting in the RFC editor queue waiting for a transport
mapping to be completed. I personally expect them to be assigned RFC numbers in 2009.

Practical Format Requirements


From a practical point of view, the message format expected (and generated by 
default in legacy mode) is:


<PRI>TIMESTAMP SP HOST SP TAG MSG(Freetext)



SP is the ASCII "space" character and the definition of the rest of the fields
can be taken from RFC3164. Please note that there also is a lot of confusion on what
syntax and semantics the TAG actually has. This format is called "legacy syslog" because
it is not well specified (as you know by now) and has been "inherited from the real world".

Rsyslog offers two parsers: one for the upcoming RFC series and one for legacy format. We 
concentrate on the later. That parser applies some logic to detect missing hostnames,
is able to handle various ways the TIMESTAMP is typically malformed. In short it applies
a lot of guesswork in trying to figure out what a message really means. I am sure the
guessing algorithm can be improved, and I am always trying that when I see new malformed
messages (and there is an ample set of them...). However, this finds its limits where
it is not possible to differentiate between two entities which could be either.
For example, look at this message:


<144>Tue Sep 23 11:40:01 taghost sample message



Does it contain a hostname? Mabye. The value "taghost" is a valid hostname. Of course, it is
also a valid tag. If it is a hostname, the tag's value is "sample" and the msg value is "message".
Or is the hostname missing, the tag is "taghost" and msg is "sample message"? As a human, I tend
to say the later interpretation is correct. But that's hard to tell the message parser (and, no, I do
not intend to apply artificial intelligence just to guess what the hostname value is...).

One approach is to configure the parser so that it never expects hostnames. This becomes problematic
if you receive messages from multiple devices. Over time, I may implement parser conditionals,
but this is not yet available and I am not really sure if it is needed comlexity...

Things like this, happen. Even more scary formats happen in practice. Even from mainstream
vendors. For example, I was just asked about this message (which, btw, finally made me
write this article here):



If you compare it with the format RFC3164 "suggests", you'll quickly notice that
the message is "a bit" malformed. Actually, even my human intelligence is not sufficient
to guess if there is a TAG or not (is "[ERROR]" a tag or part of the message). I may not be
the smartest guy, but don't expect me to program a parser that is smarter than me.

To the best of my konwledge, these vendor's device's syslog format can be configured, so it
would proabably be a good idea to include a (sufficiently well-formed) timestamp,
the sending hostname and (maybe?) a tag to make this message well parseable.
I will also once again take this sample and see if we can apply some guesswork.
For example, "[" can not be part of a well-formed TIMESTAMP, so logic can conclude
there is not TIMESTAMP. Also, "[" can not be used inside a valid hostname, so
logic can conclude that the message contains no hostname. Even if I implement this
logic (which I will probably do), this is a partial solution: it is impossible to
guess if there is a tag or not (honestly!). And, even worse, it is a solution only for
those set of messages that can be handled by the logic described. Now consider this 
hypothetical message:


"<130> [ERROR] host.example.net 2008-09-23 11-40-22 PST iapp_socket_task.c 399: iappSocketTask: iappRecvPkt returned error"



Obviously, it requires additional guesswork. If we iterate over all the cases, we
can very quickly see that it is impossible to guess everything correct. In the example above
we can not even surely tell if PST should be a timezone or some other message property.

A potential solution is to generate a parser-table based parser, but this requires
considerable effort and also has quite some runtime overhead. I try to avoid this for
now (but I may do it, especially if someone sponsors this work ;)). Side-note: if you want
to be a bit scared about potential formats, you may want to have a look at my paper
"On the Nature of Syslog Data".

Work-Around


The number one work-around is to configure your devices so that they emit
(sufficiently) well-formed messages. You should by now know what these look
like.

If that cure is not available, there are some things you can do in rsyslog to
handle the situation. First of all, be sure to read about
rsyslog.conf format
and the property replacer and properties specifically.
You need to understand that everything is configured in rsyslog. And that the message is parsed
into properties. There are also properties available which do not stem back directly to parsing.
Most importantly, %fromhost% property holds the name of the system rsyslog received
the message from. In non-relay cases, this can be used instead of hostname. In relay cases,
there is no cure other than to either fix the orginal sender or at least one of the
relays in front of the rsyslog instance in question. Similarly, you can use %timegenerated%
instead of %timereported%. Timegenerated is the time the message hit rsyslog for the first
time. For non-relayed, locally connected peers, Timegenerated should be a very close approximation
of the actual time a message was formed at the sender (depending, of course, on potential
internal queueing inside the sender).
Also, you may use the 
%rawmsg% property together with the several extraction modes the property replacer supports.
Rawmsg contains the message as it is received from the remote peer. In a sense, you can
implement a post-parser with this method.

To use these properties, you need to define your own templates and assign them. Details
can be found in the above-quoted documentation. Just let's do a quick example. Let's say
you have the horrible message shown above and can not fix the sending device for
some good reason. In rsyslog.conf, you used to say:


*.* /var/log/somefile



Of course, things do not work out well with that ill-formed message. So you decide
to dump the rawmsg to the file and pull the remote host and time of message generation
from rsyslog's internal properties (which, btw, is clever, because otherwise there is no
indication of these two properties...). So you need to define a template for that and
make sure the template is used with your file logging action. This is how it may look:


$template, MalfromedMsgFormater,"%timegenerated% %fromhost% %rawmsg:::drop-last-lf%\n"
*.* /var/log/somefile;MalformedMsgFormatter



This will make your log much nicer, but not look perfect. Experiment a bit
with the available properties and replacer extraction options to fine-tune it
to your needs.

The Ultimate Solution...


Is available with rsyslog 5.3.4 and above. Here, we can define so-called custom
parsers. These are plugin modules, written in C and adapted to a specific message format
need. The big plus of custom parsers is that they offer excellent performance and unlimited
possibilities - far better than any work-around could do. Custom parsers can be
bound to specific rule sets
(and thus listening) ports with relative ease. The only con is that they must be written.
However, if you are lucky, a parser for your device may already exist. If not, you can
opt to write it yourself, what is not too hard if you know some C. Alternatively,
Adiscon can program one for you as part of the
rsyslog professional services offering.
In any case, you should seriously consider custom parsers as an alternative if you can not 
reconfigure your device to send decent message format.

Wrap-Up


Syslog message format is not sufficiently standardized. There exists a weak
"standard" format, which is used by a good number of implementations. However, there
exist many others, including mainstream vendor implementations, which have a 
(sometimes horribly) different format. Rsyslog tries to deal with anomalies but
can not guess right in all instances. If possible, the sender should be configured
to submit well-formed messages. If that is not possible, you can work around these
issues with rsyslog's property replacer and template system. Or you can use a suitable
message parser or write one for your needs.

I hope this is a useful guide. You may also have a look at the 
rsyslog troubleshooting guide for further help and places where
to ask questions.

Free Support for Rsyslog




Free Services for Rsyslog


A personal word from Rainer, the lead developer of rsyslog:

The rsyslog community provides ample free support resources. Please see our
troubleshooting guide to get started.


Every now and then I receive private mail with support questions. I appreciate
any feedback, but I must limit my resources so that I can help driver a great logging
system forward.

To do so, I have decided not to reply to unsolicited support emails, at least not
with a solution (but rather a link to this page ;)). I hope this does not offend you. The
reason is quite simple: If I do personal support, you gain some advantage without
contributing something back. Think about it: if you ask your question on the public
forum or mailing list, other with the same problem can you and, most importantly, even
years later find your post (and the answer) and get the problem solved. So by
solving your issue in public, you help create a great community ressource and also
help your fellow users finding solutions quicker. In the long term, this
also contributes to improved code because the more questions users can find
solutions to themselves, the fewer I need to look at.

But it comes even better: the rsyslog community is much broader than Rainer ;) - there
are helpful other members hanging around at the public places. They often answer
questions, so that I do not need to look at them (btw, once again a big "thank you", folks!).
And, more important, those folks have different background than me. So they often
either know better how to solve your problem (e.g. because it is distro-specific)
or they know how to better phrase it (after all, I like abstract terms and concepts ;)).
So you do yourself a favor if you use the public places.

An excellent place to go to is the
rsyslog forum inside the
knowledge base (which in itself is a great place to visit!). For those used to
mailing lists, the
rsyslog mailing list
also offers excellent advise.

Don't like to post your question in a public place? Well, then you should
consider purchasing rsyslog professional support.
The fees are very low and help fund the project. If you use rsyslog seriously inside
a corporate environment, there is no excuse for not getting one of the support
packages ;)

Of course, things are different when I ask you to mail me privately. I'll usually do
that when I think it makes sense, for example when we exchange debug logs.

I hope you now understand the free support options and the reasoning for them.
I hope I haven't offended you with my words - this is not my intension. I just needed to
make clear why there are some limits on my responsiveness. Happy logging!

Writing syslog messages
to MySQL, PostgreSQL or any other supported Database


Written by Rainer
Gerhards with some additions by Marc
Schiffbauer (2008-02-28)


Abstract


In this paper, I describe
how to write syslog
messages to a MySQL
or PostgreSQL
database. Having syslog messages
in a database is often handy, especially when you intend to set up a
front-end for viewing them. This paper describes an approach with
rsyslogd,
an alternative enhanced syslog daemon natively supporting MySQL and
PostgreSQL. I describe the components needed to be installed and how
to configure them. Please note that as of this writing, rsyslog
supports a variety of databases. While this guide is still MySQL- and
PostgreSQL-focused, you can probably use it together with other ones
too. You just need to modify a few settings.


Background


In many cases, syslog data is simply
written to text files. This approach has some advantages, most
notably it is very fast and efficient. However, data stored in text
files is not readily accessible for real-time viewing and analysis.
To do that, the messages need to be in a database. There are various
ways to store syslog messages in a database. For example, some have
the syslogd write text files which are later feed via a separate
script into the database. Others have written scripts taking the data
(via a pipe) from a non-database-aware syslogd and store them as they
appear. Some others use database-aware syslogds and make them write
the data directly to the database. In this paper, I use that "direct
write" approach. I think it is superior, because the syslogd
itself knows the status of the database connection and thus can
handle it intelligently (well ... hopefully ;)). I use rsyslogd to
acomplish this, simply because I have initiated the rsyslog project
with database-awareness as one goal.


One word of caution:
while message storage in the database provides an excellent
foundation for interactive analysis, it comes at a cost. Database i/o
is considerably slower than text file i/o. As such, directly writing
to the database makes sense only if your message volume is low enough
to allow a) the syslogd, b) the network, and c) the database server
to catch up with it. Some time ago, I have written a paper on
optimizing
syslog server performance. While this paper
talks about Window-based solutions, the ideas in it are generic
enough to apply here, too. So it might be worth reading if you
anticipate medium high to high traffic. If you anticipate really high
traffic (or very large traffic spikes), you should seriously consider
forgetting about direct database writes - in my opinion, such a
situation needs either a very specialized system or a different
approach (the text-file-to-database approach might work better for
you in this case). 



Overall System Setup


In this paper, I concentrate on
the server side. If you are thinking about interactive syslog message
review, you probably want to centralize syslog. In such a scenario,
you have multiple machines (the so-called clients) send their data to
a central machine (called server in this context). While I expect
such a setup to be typical when you are interested in storing
messages in the database, I do not describe how to set it up. This is
beyond the scope of this paper. If you search a little, you will
probably find many good descriptions on how
to centralize syslog. If you do that, it might be a good idea to do
it securely, so you might also be interested in my paper on
ssl-encrypting
syslog message transfer.


No matter how the messages arrive at
the server, their processing is always the same. So you can use this
paper in combination with any description for centralized syslog
reporting.


As I already said, I use
rsyslogd on the server. It has intrinsic support for talking to the
supported databases. For obvious reasons, we also need an instance of
MySQL or PostgreSQL running. To keep us focused, the setup of the
database itself is also beyond the scope of this paper. I assume that
you have successfully installed the database and also have a
front-end at hand to work with it (for example, phpMyAdmin
or phpPgAdmin.
Please make sure that this is installed, actually working and you
have a basic understanding of how to handle it.


Setting up the system


You need to download and
install rsyslogd first. Obtain it from the rsyslog
site. Make sure that you disable stock
syslogd, otherwise you will experience some difficulties. On some
distributions  (Fedora 8 and above, for example), rsyslog may
already by the default syslogd, in which case you obviously do not
need to do anything specific. For many others, there are prebuild
packages available. If you use either, please make sure that you have
the required database plugins for your database available. It usually
is a separate package and typically not
installed by default.


It is important to understand
how rsyslogd talks to the database. In rsyslogd, there is the concept
of "templates". Basically, a template is a string that
includes some replacement characters, which are called "properties"
in rsyslog. Properties are accessed via the "Property
Replacer". Simply said, you access
properties by including their name between percent signs inside the
template. For example, if the syslog message is "Test", the
template "%msg%" would be expanded to "Test".
Rsyslogd supports sending template text as a SQL statement to the
database. As such, the template must be a valid SQL statement. There
is no limit in what the statement might be, but there are some
obvious and not so obvious choices. For example, a template "drop
table xxx" is possible, but does not make an awful lot of sense.
In practice, you will always use an "insert" statement
inside the template.


An example: if you would just like to
store the msg part of the full syslog message, you have probably
created a table "syslog" with a single column "message".
In such a case, a good template would be "insert into
syslog(message) values ('%msg%')". With the example above, that
would be expanded to "insert into syslog(message)
values('Test')". This expanded string is then sent to the
database. It's that easy, no special magic. The only thing you must
ensure is that your template expands to a proper SQL statement and
that this statement matches your database design.


Does that mean you need to
create database schema yourself and also must fully understand
rsyslogd's properties? No, that's not needed. Because we anticipated
that folks are probably more interested in getting things going
instead of designing them from scratch. So we have provided a default
schema as well as build-in support for it. This schema also offers an
additional benefit: rsyslog is part of Adiscon's
MonitorWare product
line (which includes open source and closed
source members). All of these tools share the same default schema and
know how to operate on it. For this reason, the default schema is
also called the "MonitorWare Schema". If you use it, you
can simply add phpLogCon,
a GPLed syslog web interface, to your system
and have instant interactive access to your database. So there are
some benefits in using the provided schema.


The schema definition is contained in
the file "createDB.sql". It comes with the rsyslog package
and one can be found for each supported database type (in the plugins
directory). Review it to check that the database name is acceptable
for you. Be sure to leave the table and field names unmodified,
because otherwise you need to customize rsyslogd's default sql
template, which we do not do in this paper. Then, run the script with
your favorite SQL client. Double-check that the table was
successfully created.


It is important to note that the
correct database encoding must be used so that the database will
accept strings independend of the string encoding. This is an
important part because it can not be guarantied that all syslog
messages will have a defined character encoding. This is especially
true if the rsyslog-Server will collect messages from different
clients and different products. 



For example PostgreSQL may refuse to
accept messages if you would set the database encoding to “UTF8”
while a client is sending invalid byte sequences for that encoding. 



Database support in rsyslog is
integrated via loadable plugin modules. To use the database
functionality, the database plugin must be enabled in the config file
BEFORE the first database table action is used. This is done by
placing the


$ModLoad ommysql


directive at the begining of /etc/rsyslog.conf for
MySQL and


$ModLoad ompgsql


for
PostgreSQL.


For
other databases, use their plugin name (e.g. omoracle).


Next, we need to tell rsyslogd to write data to
the database. As we use the default schema, we do NOT need to define
a template for this. We can use the hardcoded one (rsyslogd handles
the proper template linking). So all we need to do e.g. for MySQL is
add a simple selector line to /etc/rsyslog.conf:


*.*      
:ommysql:database-server,database-name,database-userid,database-password


Again, other databases have other selector names,
e.g. ":ompgsql:" instead of ":ommysql:". See the
output plugin's documentation for details.


In many cases, the database will run
on the local machine. In this case, you can simply use "127.0.0.1"
for database-server. This can be especially advisable, if you
do not need to expose the database to any process outside of the
local machine. In this case, you can simply bind it to 127.0.0.1,
which provides a quite secure setup. Of course, rsyslog also supports
remote database instances. In that case, use the remote server name
(e.g. mydb.example.com) or IP-address. The database-name by
default is "Syslog". If you have modified the default, use
your name here. Database-userid and -password are the
credentials used to connect to the database. As they are stored in
clear text in rsyslog.conf, that user should have only the least
possible privileges. It is sufficient to grant it INSERT privileges
to the systemevents table, only. As a side note, it is strongly
advisable to make the rsyslog.conf file readable by root only - if
you make it world-readable, everybody could obtain the password (and
eventually other vital information from it). In our example, let's
assume you have created a database user named "syslogwriter"
with a password of "topsecret" (just to say it bluntly:
such a password is NOT a good idea...). If your database is on the
local machine, your rsyslog.conf line might look like in this sample:


*.*      
:ommysql:127.0.0.1,Syslog,syslogwriter,topsecret


Save rsyslog.conf, restart rsyslogd - and you
should see syslog messages being stored in the "systemevents"
table!


The example line stores every message
to the database. Especially if you have a high traffic volume, you
will probably limit the amount of messages being logged. This is easy
to accomplish: the "write database" action is just a
regular selector line. As such, you can apply normal selector-line
filtering. If, for example, you are only interested in messages from
the mail subsystem, you can use the following selector line:


mail.*       :ommysql:127.0.0.1,syslog,syslogwriter,topsecret


Review the rsyslog.conf
documentation for details on selector lines and their filtering.


You have now completed
everything necessary to store syslog messages to the a database.
If you would like to try out a front-end, you might want to look at
phpLogCon,
which displays syslog data in a browser. As of this writing,
phpLogCon is not yet a powerful tool, but it's open source, so it
might be a starting point for your own solution.


On Reliability...


Rsyslogd writes syslog messages
directly to the database. This implies that the database must be
available at the time of message arrival. If the database is offline,
no space is left or something else goes wrong - rsyslogd can not
write the database record. If rsyslogd is unable to store a message,
it performs one retry. This is helpful if the database server was
restarted. In this case, the previous connection was broken but a
reconnect immediately succeeds. However, if the database is down for
an extended period of time, an immediate retry does not help.


Message loss in this scenario
can easily be prevented with rsyslog. All you need to do is run the
database writer in queued mode. This is now described in a generic
way and I do not intend to duplicate it here. So please be sure to
read "Handling
a massive syslog database insert rate with Rsyslog",
which describes the scenario and also includes configuration
examples.


Conclusion


With minimal effort, you can use
rsyslogd to write syslog messages to a database. You can even make it
absolutely fail-safe and protect it against database server downtime.
Once the messages are arrived there, you can interactively review and
analyze them. In practice, the messages are also stored in text files
for longer-term archival and the databases are cleared out after some
time (to avoid becoming too slow). If you expect an extremely high
syslog message volume, storing it in real-time to the database may
outperform your database server. In such cases, either filter out
some messages or used queued mode (which in general is recommended
with databases).


The method outlined in this paper
provides an easy to setup and maintain solution for most use cases.

# WARNING: This is not a manual, the full manual of rsyslog configuration is in
# rsyslog.conf (5) manpage
#
# "$" starts lines that contain new directives. The full list of directives
# can be found in /usr/share/doc/rsyslog-1.19.6/doc/rsyslog_conf.html or online
# at http://www.rsyslog.com/doc if you do not have (or find) a local copy.
#
# Set syslogd options

#                 Some global directives
#                 ----------------------

# $AllowedSender - specifies which remote systems are allowed to send syslog messages to rsyslogd
# --------------
$AllowedSender UDP, 127.0.0.1, 192.0.2.0/24, [::1]/128, *.example.net, somehost.example.com

# $UMASK - specifies the rsyslogd processes' umask
# ------
$umask 0000

# $FileGroup - Set the group for dynaFiles newly created
# ----------
$FileGroup loggroup

# $FileOwner - Set the file owner for dynaFiles newly created.
# ----------
$FileOwner loguser

# $IncludeConfig - include other files into the main configuration file
# --------------
$IncludeConfig /etc/some-included-file.conf    # one file
$IncludeConfig /etc/rsyslog.d/                 # whole directory (must contain the final slash)

# $ModLoad - Dynamically loads a plug-in and activates it
# --------
$ModLoad ommysql  # load MySQL functionality
$ModLoad /rsyslog/modules/somemodule.so # load a module via absolute path



#                       Templates
#                       ---------

# Templates allow to specify any format a user might want.
# They MUST be defined BEFORE they are used.

# A template consists of a template directive, a name, the actual template text
# and optional options. A sample is:
#
$template MyTemplateName,"\7Text %property% some more text\n",

#  where:
#   * $template - tells rsyslog that this line contains a template.
#   * MyTemplateName - template name. All other config lines refer to this name.
#   * "\7Text %property% some more text\n" - templage text

# The backslash is an escape character, i.e. \7 rings the bell, \n is a new line.
# To escape:
# % = \%
# \ = \\

# Template options are case-insensitive. Currently defined are:
# sql      format the string suitable for a SQL statement. This will replace single
#          quotes ("'") by two single quotes ("''") to prevent the SQL injection 
#          (NO_BACKSLASH_ESCAPES turned off)
# stdsql - format the string suitable for a SQL statement that is to
#          be sent  to  a standards-compliant sql server. 
#          (NO_BACKSLASH_ESCAPES turned on)



#               Properties inside templates
#               ---------------------------

# Properties can be modified by the property replacer. They are accessed
# inside the template by putting them between percent signs. The full syntax is as follows:

#     %propname:fromChar:toChar:options%

# FromChar and toChar are used to build substrings. 
# If you need to obtain the first 2 characters of the
# message text, you can use this syntax: 
"%msg:1:2%".
# If you do not whish to specify from and to, but you want to
# specify options, you still need to include the colons. 

# For example, to convert the full message text to lower case only, use 
#     "%msg:::lowercase%".

# The full list of property options can be found in rsyslog.conf(5) manpage



#               Samples of template definitions
#               -------------------------------

# A template that resambles traditional syslogd file output:
$template TraditionalFormat,"%timegenerated% %HOSTNAME% %syslogtag%%msg:::drop-last-lf%\n"

# A more verbose template:
$template precise,"%syslogpriority%,%syslogfacility%,%timegenerated::fulltime%,%HOSTNAME%,%syslogtag%,%msg%\n"

# A template that resembles RFC 3164 on-the-wire format:
# (yes, there is NO space betwen syslogtag and msg! that's important!)
$template RFC3164fmt,"<%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag%%msg%"

# a template resembling traditional wallmessage format:
$template wallmsg,"\r\n\7Message from syslogd@%HOSTNAME% at %timegenerated% ...\r\n %syslogtag%%msg%\n\r"

# The template below emulates winsyslog format, but we need to check the time
# stamps used. It is also a good sampleof the property replacer in action.
$template WinSyslogFmt,"%HOSTNAME%,%timegenerated:1:10:date-rfc3339%,%timegenerated:12:19:date-rfc3339%,%timegenerated:1:10:date-rfc3339%,%timegenerated:12:19:date-rfc3339%,%syslogfacility%,%syslogpriority%,%syslogtag%%msg%\n"

# A template used for database writing (notice it *is* an actual
# sql-statement):
$template dbFormat,"insert into SystemEvents (Message, Facility,FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values ('%msg%', %syslogfacility%, '%HOSTNAME%',%syslogpriority%, '%timereported:::date-mysql%', '%timegenerated:::date-mysql%', %iut%, '%syslogtag%')",sql



#                       Samples of rules
#                       ----------------
# Regular file
# ------------
*.*     /var/log/traditionalfile.log;TraditionalFormat      # log to a file in the traditional format

# Forwarding to remote machine
# ----------------------------
*.*	@172.19.2.16		# udp (standard for syslog)
*.*	@@172.19.2.17		# tcp

# Database action
# ---------------
# (you must have rsyslog-mysql package installed)

*.*	>hostname,dbname,userid,password	# (default Monitorware schema, can be created by /usr/share/doc/rsyslog-mysql-1.19.6/createDB.sql)

# And this one uses the template defined above:
*.*	>hostname,dbname,userid,password;dbFormat

# Program to execute
# ------------------
*.*			^alsaunmute 	# set default volume to soundcard

# Filter using regex
# ------------------
# if the user logges word rulez or rulezz or rulezzz or..., then we will shut down his pc
# (note, that + have to be double backslashed...)
:msg, regex, "rulez\\+"	 ^poweroff

# A more complex example
# ----------------------
$template bla_logged,"%timegenerated% the BLA was logged"

RulesetCreateMainQueue - rsyslog.conf file


rsyslog.conf configuration directive


$RulesetCreateMainQueue


Type: ruleset-specific configuration directive


Parameter Values: boolean (on/off, yes/no)


Available since: 5.3.5+


Default: off


Description:



Rulesets may use their own "main" message queue for message submission. Specifying
this directive, inside a ruleset definition, turns this on. This is both a performance
enhancement and also permits different rulesets (and thus different inputs within the same
rsyslogd instance) to use different types of main message queues.

The ruleset queue is created with the parameters that are specified for the main message
queue at the time the directive is given. If different queue configurations are desired,
different main message queue directives must be used in front of the $RulesetCreateMainQueue
directive. Note that this directive may only be given once per ruleset. If multiple statements
are specified, only the first is used and for the others error messages are emitted.

Note that the final set of ruleset configuration directives specifies the parameters for
the default main message queue.

To learn more about this feature, please be sure to read about
multi-ruleset support in rsyslog.

Caveats:

The configuration statement "$RulesetCreateMainQueue off" has no effect at all.
The capability to specify this is an artifact of the current (ugly!) configuration 
language.


Example:


This example sets up a tcp server with three listeners. Each of these
three listener is bound to a specific ruleset. As a performance optimization,
the rulesets all receive their own private queue. The result is that received messages
can be independently processed. With only a single main message queue, we would have
some lock contention between the messages. This does not happen here. Note that in this
example, we use different processing. Of course, all messages could also have been
processed in the same way ($IncludeConfig may be useful in that case!).




Note the positions of the directives. With the current config language,
position is very important. This is ugly, but unfortunately the way it currently
works.

$EscapeControlCharactersOnReceive


Type: global configuration directive


Default: on


Description:


This directive instructs rsyslogd to replace control characters during reception of the message. The intent is to provide a way to stop non-printable messages from entering the syslog system as whole. If this option is turned on, all control-characters are converted to a 3-digit octal number and be prefixed with the $ControlCharacterEscapePrefix character (being '\' by default). For example, if the BEL character (ctrl-g) is included in the message, it would be converted to "\007". To be compatible to sysklogd, this option must be turned on.


Warning:


    
	
  • turning on this option most probably destroys non-western character sets 
	(like Japanese, Chinese and Korean)
    • 
	
  • turning on this option destroys digital signatures if such exists inside 
	the message
    • 
	
  • if turned on, the drop-cc, space-cc and escape-cc
	property replacer options do not work 
	as expected because control characters are already removed upon message 
	reception. If you intend to use these property replacer options, you must 
	turn off $EscapeControlCharactersOnReceive.

$FileGroup


Type: global configuration directive


Default: 


Description:


Set the group for dynaFiles newly created. Please note that this setting does not affect the group of files already existing. The parameter is a group name, for which the groupid is obtained by rsyslogd during startup processing. Interim changes to the user mapping are not detected.

Compatibility notes for rsyslog v4



Compatibility Notes for rsyslog v4


Written by Rainer Gerhards
(2009-07-15)


The changes introduced in rsyslog v4 are numerous, but not very intrusive.
This document describes things to keep in mind when moving from v3 to v4. It 
does not list enhancements nor does it talk about compatibility concerns introduced
by v3 (for this, see the rsyslog v3 compatibility notes).

HUP processing


With v3 and below, rsyslog used the traditional HUP behaviour. That meant that
all output files are closed and the configuration file is re-read and the new configuration
applied.

With a program as simple and static as sysklogd, this was not much of an issue. The
most important config settings (like udp reception) of a traditional syslogd can not be
modified via the configuration file. So a config file reload only meant setting up a new set of filters. It also didn't account as problem that while doing so messages may be lost - without
any threading and queuing model, a traditional syslogd will potentially always loose
messages, so it is irrelevant if this happens, too, during the short config re-read
phase.

In rsyslog, things are quite different: the program is more or less a framework into
which loadable modules are loaded as needed for a particular configuration. The software
that will acutally be running is taylored via the config file. Thus, a re-read of
the config file requires a full, very heavy restart, because the software acutally
running with the new config can be totally different from what ran with the old config.

Consequently, the traditional HUP is a very heavy operation and may even cause some
data loss because queues must be shut down, listeners stopped and so on. Some of these
operations (depending on their configuration) involve intentional message loss. The operation
also takes up a lot of system resources and needs quite some time (maybe seconds) to be
completed. During this restart period, the syslog subsytem is not fully available.

From the software developer's point of view, the full restart done by a HUP is rather complex,
especially if user-timeout limits set on action completion are taken into consideration (for
those in the know: at the extreme ends this means we need to cancel threads as a last resort,
but than we need to make sure that such cancellation does not happen at points where it
would be fatal for a restart). A regular restart, where the process is actually terminated, is
much less complex, because the operating system does a full cleanup after process termination,
so rsyslogd does not need to take care for exotic cleanup cases and leave that to the OS.
In the end result, restart-type HUPs clutter the code, increase complexity (read: add bugs)
and cost performance.

On the contrary, a HUP is typically needed for log rotation, and the real desire is
to close files. This is a non-disruptive and very lightweigth operation.

Many people have said that they are used to HUP the syslogd to apply configuration
changes. This is true, but it is questionable if that really justifies all the cost that
comes with it. After all, it is the difference between typing

$ kill -HUP `cat /var/run/rsyslogd.pid`


versus

$ /etc/init.d/rsyslog restart


Semantically, both is mostly the same thing. The only difference is that with the restart
command rsyslogd can spit config error message to stderr, so that the user is able to see 
any problems and fix them. With a HUP, we do not have access to stderr and thus can log
error messages only to their configured destinations; exprience tells that most users
will never find them there. What, by the way, is another strong argument against
restarting rsyslogd by HUPing it.

So a restart via HUP is not strictly necessary
and most other deamons require that a restart command is typed in if a restart is required.

Rsyslog will follow this paradigm in the next versions, resulting in many benefits. In v4,
we provide some support for the old-style semantics. We introduced a setting $HUPisRestart
which may be set to "on" (tradional, heavy operation)
or "off" (new, lightweight "file close only" operation).
The initial versions had the default set to traditional behavior, but starting with 4.5.1
we are now using the new behavior as the default.

Most importantly, this may break some scripts, but my sincere belief is that
there are very few scripts that automatically change rsyslog's config and then do a
HUP to reload it. Anyhow, if you have some of these, it may be a good idea to change
them now instead of turning restart-type HUPs on. Other than that, one mainly needs
to change the habit of how to restart rsyslog after a configuration change.

Please note that restart-type HUP is depricated and will go away in rsyslog v5.
So it is a good idea to become ready for the new version now and also enjoy some of the
benefits of the "real restart", like the better error-reporting capability.

Note that code complexity reduction (and thus performance improvement) needs the restart-type
HUP code to be removed, so these changes can (and will) only happen in version 5.

outchannels

Note: as always documented, outchannels are an experimental feature that may be 
removed and/or changed in the future.
There is one concrete change done starting with 4.6.7: let's assume an
outchannel "mychannel" was defined. Then, this channel could be used inside an

*.* $mychannel

This is still supported and will remain to be supported in v4. However, there is
a new variant which explicitely tells this is to be handled by omfile. This new
syntax is as follows:

*.* :omfile:$mychannel

Note that future versions, specifically starting with v6, the older syntax is no
longer supported. So users are strongly advised to switch to the new syntax. As an
aid to the conversion process, rsyslog 4.7.4 and above issue a warning message
if the old-style directive is seen -- but still accept the old syntax without
any problems.

Keep the log file size accurate with log rotation

Log rotation with rsyslog

		
Written by
		Michael Meckelein


Situation



Your environment does not allow you to store tons of logs? 
You have limited disc space available for logging, for example
you want to log to a 124 MB RAM usb stick? Or you do not want to
keep all the logs for months, logs from the last days is sufficient?
Think about log rotation.



Log rotation based on a fixed log size



This small but hopefully useful article will show you the way 
to keep your logs at a given size. The following sample is based on 
rsyslog illustrating a simple but effective log rotation with a 
maximum size condition.



Use Output Channels for fixed-length syslog files



Lets assume you do not want to spend more than 100 MB hard 
disc space for you logs. With rsyslog you can configure Output 
Channels to achieve this. Putting the following directive



# start log rotation via outchannel
# outchannel definiation
$outchannel log_rotation,/var/log/log_rotation.log, 52428800,/home/me/./log_rotation_script 
#  activate the channel and log everything to it 
*.* :omfile:$log_rotation
# end log rotation via outchannel

 


to ryslog.conf instruct rsyslog to log everything to the destination file 
'/var/log/log_rotation.log' until the give file size of 50 MB is reached. If 
the max file size is reached it will perform an action. In our case it executes 
the script /home/me/log_rotation_script which contains a single command:



mv -f /var/log/log_rotation.log /var/log/log_rotation.log.1




This moves the original log to a kind of backup log file. 
After the action was successfully performed rsyslog creates a new /var/log/log_rotation.log 
file and fill it up with new logs. So the latest logs are always in log_roatation.log.



Conclusion



With this approach two files for logging are used, each with a maximum size of 50 MB. So 
we can say we have successfully configured a log rotation which satisfies our requirement. 
We keep the logs at a fixed-size level of100 MB.

RELP Input Module



back


RELP Input Module


Module Name:    imrelp


Author: Rainer Gerhards


Description:


Provides the ability to receive syslog messages via the
reliable RELP protocol. This module requires librelp to be
present on the system. From the user's point of view, imrelp works much
like imtcp or imgssapi, except that no message loss can occur. Please
note that with the currently supported relp protocol version, a minor
message duplication may occur if a network connection between the relp
client and relp server breaks after the client could successfully send
some messages but the server could not acknowledge them. The window of
opportunity is very slim, but in theory this is possible. Future
versions of RELP will prevent this. Please also note that rsyslogd may
lose a few messages if rsyslog is shutdown while a network conneciton
to the server is broken and could not yet be recovered. Future version
of RELP support in rsyslog will prevent that. Please note that both
scenarios also exists with plain tcp syslog. RELP, even with the small
nits outlined above, is a much more reliable solution than plain tcp
syslog and so it is highly suggested to use RELP instead of plain tcp.
Clients send messages to the RELP server via omrelp.



Configuration Directives:


    

  • Port <port>
    
Starts a RELP server on selected port
    • 


Caveats/Known Bugs:

    

  • ruleset can only be bound via legacy configuration format
    • 

  • To obtain the remote system's IP address, you need to have at least
librelp 1.0.0 installed. Versions below it return the hostname instead
of the IP address.
    • 

  • Contrary to other inputs, the ruleset can only be bound to all listeners,
not specific ones. This is due to a currently existing limitation in librelp.



Sample:


This sets up a RELP server on port 20514.






Legacy Configuration Directives:


    

  • InputRELPServerBindRuleset <name> (available in 6.3.6+)
    
Binds the specified ruleset to all RELP listeners.

  • InputRELPServerRun <port>

RFC3195 Input Module (im3195)



back


RFC3195 Input Module


Module Name:    im3195


Author: Rainer Gerhards
<rgerhards@adiscon.com>


Description:


Receives syslog messages via RFC 3195. The RAW profile is fully implemented and the 
COOKED profile is provided in an experimental state. This module uses
liblogging for the actual protocol handling.


Configuration Directives:


    

  • $Input3195ListenPort <port>
    
The port on which imklog listens for RFC 3195 messages. The default port is 601
(the IANA-assigned port)
    • 


Caveats/Known Bugs:

Due to no demand at all for RFC3195, we have converted rfc3195d
to this input module, but we have NOT conducted any testing. Also,
the module does not yet properly handle the recovery case. If someone
intends to put this module into production, good testing should be
cunducted. It also is a good idea to notify the rsyslog project that you intend to use
it in production. In this case, we'll probably give the module another
cleanup. We don't do this now because so far it looks just like a big
waste of time.

Currently only a single listener can be defined. That one binds to all interfaces.


Sample:


The following sample accepts syslog messages via RFC 3195 on port 1601.

Building rsyslog from the source repository



Building rsyslog from the source repository


In most cases, people install rsyslog either via a package or use an "official"
distribution tarball to generate it. But there may be situations where it is desirable
to build directly from the source repository. This is useful for people who would like to
participate in development or who would like to use the latest, not-yet-released code.
The later may especially be the case if you are asked to try out an experimental version.

Building from the repsitory is not much different than building from the source
tarball, but some files are missing because they are output files and thus do not
belong into the repository.

Obtaining the Source


First of all, you need to download the sources. Rsyslog is currently kept in a git
repository. You can clone this repository either via http or git protocol (with the later
being much faster. URLS are:

    

  • git://git.adiscon.com/git/rsyslog.git

  • http://git.adiscon.com/git/rsyslog.git



There is also a browsable version (gitweb) available at
http://git.adiscon.com/?p=rsyslog.git;a=summary.
This version also offers snapshots of each commit for easy download. You can use these if
you do not have git present on your system.

After you have cloned the repository, you are in the master branch by default. This
is where we keep the devel branch. If you need any other branch, you need to do
a "git checkout --track -b branch origin/branch". For example, the command to check out
the beta branch is "git checkout --track -b beta origin/beta".

Prequisites


To build the compilation system, you need the pkg-config package (an utility for
autotools) present on your system. Otherwise, configure will fail with something like


checking for SYSLOG_UNIXAF support... yes
checking for FSSTND support... yes
./configure: line 25895: syntax error near unexpected token `RELP,'
./configure: line 25895: ` PKG_CHECK_MODULES(RELP, relp >= 0.1.1)'



Creating the Build Environment


This is fairly easy: just issue "autoreconf -fvi", which should do everything you need.
Once this is done, you can follow the usual ./configure steps just like when
you downloaded an official distribution tarball (see the
rsyslog install guide, starting at step 2,
for further details about that).


Special Compile-Time Options


On some platforms, compile-time issues occur, like the one shown below:


make[2]: Entering directory `/home/az/RSyslog/rsyslog-5.5.0/tools'
  CCLD   rsyslogd
rsyslogd-omfile.o: In function `getClockFileAccess':
/home/az/RSyslog/rsyslog-5.5.0/tools/omfile.c:91: undefined reference to `__sync_fetch_and_add_8'
/home/az/RSyslog/rsyslog-5.5.0/tools/omfile.c:91: undefined reference to `__sync_fetch_and_add_8'
/home/az/RSyslog/rsyslog-5.5.0/tools/omfile.c:91: undefined reference to `__sync_fetch_and_add_8'



Note that the exact error messages can be different. These type of errors stem down to
atomic instruction support in GCC, which is somewhat depending on the machine architecture it
compiles code for. Very old machines (like the original i386) do not even at all provide support
for these instructions.

The availability of atomic instructions is vital for rsyslog - it can not be built without them.
Consequently, there is a configure check included for them. But under some circumstances,
GCC seems to report they are available, but does not provide implementations for
all of them (at least this is my observation...). The simple cure is to make sure that
GCC generates code for a modern-enough architecture. This, for example, can be done as
follows:


./configure CFLAGS="-march=i586 -mcpu=i686" --enable-imfile ... (whatever you need)



These settings should resolve the issue .

$MarkMessagePeriod


Type: specific to immark input module


Default: 1200 (20 minutes)


Description:


This specifies when mark messages are to be written to output modules. The 
time specified is in seconds. Specifying 0 is possible and disables mark 
messages. In that case, however, it is more efficient to NOT load the immark 
input module.


So far, there is only one mark message process and any subsequent 
$MarkMessagePeriod overwrites the previous.


This directive is only available after the immark input module has been 
loaded.


Sample:


$MarkMessagePeriod  600 # mark messages appear every 10 Minutes


Available since: rsyslog 3.0.0

TLS-protected syslog: generating the machine certificate




Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-06-18)





generating the machine certificate


In this step, we generate certificates for each of the machines. Please note
that both clients and servers need certificates. The certificate identifies each
machine to the remote peer. The DNSName specified inside the certificate can




be specified inside the $<object>PermittedPeer config statements.

For now, we assume that a single person (or group) is responsible for the whole
rsyslog system and thus it is OK if that single person is in posession of all
machine's private keys. This simplification permits us to use a somewhat less
complicated way of generating the machine certificates. So, we generate both the private
and public key on the CA (which is NOT a server!) and then copy them over to the
respective machines.

If the roles of machine and CA administrators are split, the private key must
be generated by the machine administrator. This is done via a certificate request.
This request is then sent to the CA admin, which in turn generates the certificate
(containing the public key). The CA admin then sends back the certificate to the
machine admin, who installs it. That way, the CA admin never get's hold of the
machine's private key. Instructions for this mode will be given in a later revision
of this document.

In any case, it is vital that the machine's private key is protected. Anybody
able to obtain that private key can imporsonate as the machine to which it belongs, thus
breaching your security.

Sample Screen Session


Text in red is user input. Please note that for some questions, there is no
user input given. This means the default was accepted by simply pressing the 
enter key.

Please note: you need to substitute the names specified below with values
that match your environment. Most importantly, machine.example.net must be replaced
by the actual name of the machine that will be using this certificate. For example,
if you generate a certificate for a machine named "server.example.com", you need 
to use that name. If you generate a certificate for "client.example.com", you need
to use this name. Make sure that each machine certificate has a unique name. If not,
you can not apply proper access control.

Distributing Files


Provide the machine with:

    

  • a copy of ca.pem

  • cert.pem

  • key.pem



This is how the relevant part of rsyslog.conf looks on the target machine:



$DefaultNetstreamDriverCAFile /home/rger/proj/rsyslog/sample/ca.pem
$DefaultNetstreamDriverCertFile /home/rger/proj/rsyslog/sample/machine-cert.pem
$DefaultNetstreamDriverKeyFile /home/rger/proj/rsyslog/sample/machine-key.pem



Never provide anyone with ca-key.pem! Also, make sure
nobody but the machine in question gets hold of key.pem.

$GssForwardServiceName


Type: global configuration directive


Default: host


Provided by: omgssapi


Description:


Specifies the service name used by the client when forwarding GSS-API wrapped messages.


The GSS-API service names are constructed by appending '@' and a hostname following "@@" in each selector.


Sample:


$GssForwardServiceName rsyslog

$UMASK


Type: global configuration directive


Default: 


Description:


The $umask directive allows to specify the rsyslogd processes' umask. If not specified, the system-provided default is used. The value given must always be a 4-digit octal number, with the initial digit being zero.


If $umask is specified multiple times in the configuration file, results may be somewhat unpredictable. It is recommended to specify it only once.


Sample:


$umask 0000


This sample removes all restrictions.

Configuration Directives


All configuration directives need to be specified on a line by their
own and must start with a dollar-sign. Note that those starting with
the word "Action" modify the next action and should be specified
in front of it.

Here is a list in alphabetical order. Follow links for a description.


Not all directives have an in-depth description right now.
Default values for them are in bold. A more in-depth description will
appear as implementation progresses.



Be sure to read information about queues in rsyslog -
many parameter settings modify queue parameters. If in doubt, use the
default, it is usually well-chosen and applicable in most cases.


    

  • $AbortOnUncleanConfig - abort startup if there is
any issue with the config file
    • 

  • $ActionExecOnlyWhenPreviousIsSuspended
    • 

  • $ActionName <a_single_word> - used primarily for documentation, e.g. when
generating a configuration graph. Available sice 4.3.1.

  • $ActionExecOnlyOnceEveryInterval <seconds> -
execute action only if the last execute is at last
<seconds> seconds in the past (more info in ommail,
but may be used with any action)
    • 

  • $ActionExecOnlyEveryNthTime <number> - If configured, the next action will
only be executed every n-th time. For example, if configured to 3, the first two messages
that go into the action will be dropped, the 3rd will actually cause the action to execute,
the 4th and 5th will be dropped, the 6th executed under the action, ... and so on. Note:
this setting is automatically re-set when the actual action is defined.
    • 

  • $ActionExecOnlyEveryNthTimeTimeout <number-of-seconds> - has a meaning only if
$ActionExecOnlyEveryNthTime is also configured for the same action. If so, the timeout
setting specifies after which period the counting of "previous actions" expires and
a new action count is begun. Specify 0 (the default) to disable timeouts.

    
Why is this option needed? Consider this case: a message comes in at, eg., 10am. That's
count 1. Then, nothing happens for the next 10 hours. At 8pm, the next
one occurs. That's count 2. Another 5 hours later, the next message
occurs, bringing the total count to 3. Thus, this message now triggers
the rule.

    
The question is if this is desired behavior? Or should the rule only be
triggered if the messages occur within an e.g. 20 minute window? If the
later is the case, you need a

    
$ActionExecOnlyEveryNthTimeTimeout 1200

    
This directive will timeout previous messages seen if they are older
than 20 minutes. In the example above, the count would now be always 1
and consequently no rule would ever be triggered.

default 0 (no delay). Simple rate-limiting!]
    •

[number is timeout in ms (1000ms is 1sec!), default 1000, 0 means
immediate!]
    • 

  • $ActionQueueTimeoutEnqueue <number> [number
is timeout in ms (1000ms is 1sec!), default 2000, 0 means indefinite]
    •

is timeout in ms (1000ms is 1sec!), default 0 (indefinite)]
    • 

  • $ActionQueueWorkerTimeoutThreadShutdown
<number> [number is timeout in ms (1000ms is 1sec!),
default 60000 (1 minute)]
    • 

  • $ActionQueueType [FixedArray/LinkedList/Direct/Disk]
    • 

  • $ActionQueueSaveOnShutdown  [on/off]

    • 

  • $ActionQueueWorkerThreads <number>, num worker threads, default 1, recommended 1
    • 

  • $ActionQueueWorkerThreadMinumumMessages <number>, default 100
    • 

  • $ActionResumeInterval
    • 

  • $ActionResumeRetryCount <number> [default 0, -1 means eternal]
    • 

  • $ActionSendResendLastMsgOnReconnect <[on/off]> specifies if the last message is to be resend when a connecition breaks and has been reconnected. May increase reliability, but comes at the risk of message duplication.

  • $ActionSendStreamDriver <driver basename> just like $DefaultNetstreamDriver, but for the specific action
    • 

  • $ActionSendStreamDriverMode <mode>, default 0, mode to use with the stream driver (driver-specific)
    • 

  • $ActionSendStreamDriverAuthMode <mode>,  authentication mode to use with the stream driver. Note that this directive requires TLS
netstream drivers. For all others, it will be ignored.
(driver-specific)
    • 

  • $ActionSendStreamDriverPermittedPeer <ID>,  accepted fingerprint (SHA1) or name of remote peer. Note that this directive requires TLS
netstream drivers. For all others, it will be ignored.
(driver-specific) - directive may go away!
    • 

  • $ActionSendTCPRebindInterval nbr- [available since 4.5.1] - instructs the TCP send
action to close and re-open the connection to the remote host every nbr of messages sent.
Zero, the default, means that no such processing is done. This directive is useful for
use with load-balancers. Note that there is some performance overhead associated with it,
so it is advisable to not too often "rebind" the connection (what
"too often" actually means depends on your configuration, a rule of thumb is
that it should be not be much more often than once per second).
    • 

  • $ActionSendUDPRebindInterval nbr- [available since 4.3.2] - instructs the UDP send
action to rebind the send socket every nbr of messages sent. Zero, the default, means
that no rebind is done. This directive is useful for use with load-balancers.
    • 

  • $ActionWriteAllMarkMessages [on/off]- [available since 5.1.5] - normally, mark messages
are written to actions only if the action was not recently executed (by default, recently means within the
past 20 minutes). If this setting is switched to "on", mark messages are always sent to actions,
no matter how recently they have been executed. In this mode, mark messages can be used as a kind of
heartbeat. Note that this option auto-resets to "off", so if you intend to use it with multiple
actions, it must be specified in front off all selector lines that should provide this 
functionality.

  • $LocalHostName [name] - this directive permits to overwrite the system
hostname with the one specified in the directive. If the directive is given
multiple times, all but the last one will be ignored. Please note that startup
error messages may be issued with the real hostname. This is by design and not
a bug (but one may argue if the design should be changed ;)). Available since
4.7.4+, 5.7.3+, 6.1.3+.

  • $LogRSyslogStatusMessages [on/off] - If set to on (the default),
rsyslog emits message on startup and shutdown as well as when it is HUPed.
This information might be needed by some log analyzers. If set to off, no such
status messages are logged, what may be useful for other scenarios.

    • 

  • $MainMsgQueueWorkerThreadMinumumMessages <number>, default 100
    • 

  • $MarkMessagePeriod (immark)
    • 

  • $MaxMessageSize <size_nbr>, default 2k - allows to specify maximum supported message size
(both for sending and receiving). The default
should be sufficient for almost all cases. Do not set this below 1k, as it would cause
interoperability problems with other syslog implementations.
    
Change the setting to e.g. 32768 if you would like to
support large message sizes for IHE (32k is the current maximum
needed for IHE). I was initially tempted to set the default to 32k,
but there is a some memory footprint with the current
implementation in rsyslog.

    If you intend to receive Windows Event Log data (e.g. via
EventReporter), you might want to
increase this number to an even higher value, as event
log messages can be very lengthy ("$MaxMessageSize 64k" is not a bad idea).
Note: testing showed that 4k seems to be
the typical maximum for UDP based syslog. This is an IP stack
restriction. Not always ... but very often. If you go beyond
that value, be sure to test that rsyslogd actually does what
you think it should do ;) It is highly suggested to use a TCP based transport
instead of UDP (plain TCP syslog, RELP). This resolves the UDP stack size restrictions.

    Note that 2k, the current default, is the smallest size that must be
supported in order to be compliant to the upcoming new syslog RFC series.

  • $ModDir
    • 

  • $ModLoad
    • 

  • $OMFileAsyncWriting [on/off], if turned on, the files will be written
in asynchronous mode via a separate thread. In that case, double buffers will be used so
that one buffer can be filled while the other buffer is being written. Note that in order
to enable $OMFileFlushInterval, $OMFileAsyncWriting must be set to "on". Otherwise, the flush
interval will be ignored. Also note that when $OMFileFlushOnTXEnd is "on" but 
$OMFileAsyncWriting is off, output will only be written when the buffer is full. This may take
several hours, or even require a rsyslog shutdown. However, a buffer flush can be forced
in that case by sending rsyslogd a HUP signal.

  • $OMFileZipLevel 0..9  [default 0] - if greater 0, turns on gzip compression
of the output file. The higher the number, the better the compression, but also the
more CPU is required for zipping.
    • 

  • $OMFileIOBufferSize <size_nbr>, default 4k, size of the buffer used to writing output data. The larger the buffer, the potentially better performance is. The default of 4k is quite conservative, it is useful to go up to 64k, and 128K if you used gzip compression (then, even higher sizes may make sense)
    • 

  • $OMFileFlushOnTXEnd <[on/off]>, default on. Omfile has the
capability to
write output using a buffered writer. Disk writes are only done when the buffer is
full. So if an error happens during that write, data is potentially lost. In cases where
this is unacceptable, set $OMFileFlushOnTXEnd to on. Then, data is written at the end
of each transaction (for pre-v5 this means after each log message) and the usual
error recovery thus can handle write errors without data loss. Note that this option
severely reduces the effect of zip compression and should be switched to off
for that use case. Note that the default -on- is primarily an aid to preserve
the traditional syslogd behaviour.
    • 

  • $omfileForceChown - force ownership change for all files
    • 

  • $RepeatedMsgContainsOriginalMsg [on/off] - "last message repeated n times" messages, if generated,
have a different format that contains the message that is being repeated.
Note that only the first "n" characters are included, with n to be at least 80 characters, most
probably more (this may change from version to version, thus no specific limit is given). The bottom
line is that n is large enough to get a good idea which message was repeated but it is not necessarily
large enough for the whole message. (Introduced with 4.1.5). Once set, it affects all following actions.
    • 

  • $RepeatedMsgReduction
    • 

  • $ResetConfigVariables
    • 

  • $Ruleset name - starts a new ruleset or switches back to one already defined.
All following actions belong to that new rule set.
the name does not yet exist, it is created. To switch back to rsyslog's
default ruleset, specify "RSYSLOG_DefaultRuleset") as the name.
All following actions belong to that new rule set. It is advised to also read
our paper on using multiple rule sets in rsyslog.
    • 

  • $RulesetCreateMainQueue on - creates
a ruleset-specific main queue.

  • $RulesetParser - enables to set
a specific (list of) message parsers to be used with the ruleset.

  • $OptimizeForUniprocessor [on/off] - turns on optimizatons which lead to better
performance on uniprocessors. If you run on multicore-machiens, turning this off lessens CPU load. The
default may change as uniprocessor systems become less common. [available since 4.1.0]
    • 

  • $PreserveFQDN [on/off) - if set to off (legacy default to remain compatible
to sysklogd), the domain part from a name that is within the same domain as the receiving
system is stripped. If set to on, full names are always used.
    • 

  • $WorkDirectory <name> (directory for spool and other work files.
Do not use trailing slashes)
    • 

  • $UDPServerAddress <IP> (imudp) -- local IP
address (or name) the UDP listens should bind to
    • 

  • $UDPServerRun <port> (imudp) -- former
-r<port> option, default 514, start UDP server on this
port, "*" means all addresses
    • 

  • $UDPServerTimeRequery <nbr-of-times> (imudp) -- this is a performance
optimization. Getting the system time is very costly. With this setting, imudp can
be instructed to obtain the precise time only once every n-times. This logic is
only activated if messages come in at a very fast rate, so doing less frequent
time calls should usually be acceptable. The default value is two, because we have
seen that even without optimization the kernel often returns twice the identical time.
You can set this value as high as you like, but do so at your own risk. The higher
the value, the less precise the timestamp.

  • $PrivDropToGroup
    • 

  • $PrivDropToGroupID
    • 

  • $PrivDropToUser
    • 

  • $PrivDropToUserID
    • 

  • $Sleep <seconds> - puts the rsyslog main thread to sleep for the specified
number of seconds immediately when the directive is encountered. You should have a
good reason for using this directive!
    • 

  • $LocalHostIPIF  <interface name> - (available since 5.9.6) - if provided, the IP of the specified
interface (e.g. "eth0") shall be used as fromhost-ip for locall-originating messages.
If this directive is not given OR the interface cannot be found (or has no IP address),
the default of "127.0.0.1" is used. Note that this directive can be given only
once. Trying to reset will result in an error message and the new value will
be ignored. Please note that modules must have support for obtaining the local
IP address set via this directive. While this is the case for rsyslog-provided
modules, it may not always be the case for contributed plugins.

    Important: This directive shall be placed right at the top of
rsyslog.conf. Otherwise, if error messages are triggered before this directive
is processed, rsyslog will fix the local host IP to "127.0.0.1", what than can
not be reset.

    • 

  • $UMASK
    • 



Where <size_nbr> or integers are specified above,
modifiers can be used after the number part. For example, 1k means
1024. Supported are k(ilo), m(ega), g(iga), t(era), p(eta) and e(xa).
Lower case letters refer to the traditional binary defintion (e.g. 1m
equals 1,048,576) whereas upper case letters refer to their new
1000-based definition (e.g 1M equals 1,000,000).


Numbers may include '.' and ',' for readability. So you can
for example specify either "1000" or "1,000" with the same result.
Please note that rsyslogd simply ignores the punctuation. From it's
point of view, "1,,0.0.,.,0" also has the value 1000.

/dev/kmsg Log Input Module (imkmsg)



back


/dev/kmsg Log Input Module


Module Name:    imkmsg


Authors: Rainer Gerhards
<rgerhards@adiscon.com>

Milan Bartos
<mbartos@redhat.com>


Description:


Reads messages from the /dev/kmsg structured kernel log and submits them to the
syslog engine.



The printk log buffer constains log records. These records are exported by /dev/kmsg
device as structured data in the following format:

  "level,sequnum,timestamp;<message text>\n"

There could be continuation lines starting with space that contains key/value pairs.



Log messages are parsed as necessary into rsyslog msg_t structure. Continuation lines are parsed
as json key/value pairs and added into rsyslog's message json representation.



Configuration Directives:


This module has no configuration directives.

Caveats/Known Bugs:

This module can't be used together with imklog module. When using one of them, make sure the other
one is not enabled.


This is Linux specific module and requires /dev/kmsg device with structured kernel logs.


Sample:


The following sample pulls messages from the /dev/kmsg log device. All
parameters are left by default, which is usually a good idea. Please
note that loading the plugin is sufficient to activate it. No directive
is needed to start pulling messages.

TLS-protected syslog: Summary




Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-07-03)





Summary


If you followed the steps outlined in this documentation set, you now have




a reasonable (for most needs) secure setup for the following environment:



You have learned about the security decisions involved and which we
made in this example. Be once again reminded that you must make sure yourself
that whatever you do matches your security needs! There is no guarantee that
what we generally find useful actually is. It may even be totally unsuitable for
your environment.

In the example, we created a rsyslog certificate authority (CA). Guard the CA's
files. You need them whenever you need to create a new machine certificate. We also saw how
to generate the machine certificates themselfs and distribute them to the individual
machines. Also, you have found some configuration samples for a sever, a client and
a syslog relay. Hopefully, this will enable you to set up a similar system in many
environments.

Please be warned that you defined some expiration dates for the certificates.
After they are reached, the certificates are no longer valid and rsyslog will NOT
accept them. At that point, syslog messages will no longer be transmitted (and rsyslogd
will heavily begin to complain). So it is a good idea to make sure that you renew the
certificates before they expire. Recording a reminder somewhere is probably a good
idea.

If you have any more questions, please visit the rsyslog forum and simply ask ;)

rsyslog vs. syslog-ng - a comparison

back

rsyslog vs. syslog-ng


Written by Rainer Gerhards
(2008-05-06), slightly updated 2012-01-09


This comparison page is rooted nearly 5 years in the past and has become severely
outdated since then. It was unmaintained for several years and contained false 
information on both syslog-ng and rsyslog as technology had advanced so much.

This page was initially written because so many people asked about a comparison when
rsyslog was in its infancy. So I tried to create one, but it was hard to maintain as both
projects grew and added feature after feature. I have to admit we did not try hard to keep
it current -- there were many other priorities. I even had forgetten about this page, when I
saw that Peter Czanik blogged about its
incorrectness (it must be noted
that Peter is wrong on RELP -- it is well alive). I now remember
that he asked me some time ago about this page, what I somehow lost... I guess he must have been
rather grumpy about that :-(

Visiting this page after so many years is interesting, because it shows how much has changed since then.
Obviously, one of my main goals in regard to syslog-ng is reached: in 2007, I blogged that 
the
world needs another syslogd in order to have healthy competition and a greate feature
set in the free editions. In my opinion, the timeline clearly tells that rsyslog's competition
has driven more syslog-ng features from the commercial to the free edition. Also, I found
it interesting to see that syslog-ng has adapted rsyslog's licensing scheme, modular design and
multi-threadedness. On the other hand, the Balabit folks have obviously done a quicker and
better move on log normalization with what they call patterndb (it is very roughly equivalent
to what rsyslog has just recently introduced with the help of liblognorm).


To that account, I think the projects are closer together than 5 years ago. I should now
go ahead and create a new feature comparison. Given previous experience, I think this does not
work out. In the future, we will probably focus on some top features, as Balabit does. However,
that requires some time and I have to admit I do not like to drop this page that has a lot of
inbound links. So I think I do the useful thing by providing these notes and removing the
syslog-ng information. So it can't be wrong on syslog-ng any more. Note that it still contains
some incorrect information about rsyslog (it's the state it had 5 years ago!). The core idea is
to start with updating the rsyslog feature sheet and from there
on work to a complete comparision. Of course, feel free to read on if you like to get some sense 
of history (and inspiration on what you can still do -- but more ;)).



Thanks,

Rainer Gerhards

While the rsyslog
project was initiated in 2004, it is
build on the main author's (Rainer Gerhards) 12+ years of
logging experience. Rainer, for example, also
wrote the first Windows
syslog server in early 1996 and invented the eventlog-to-syslog
class of applications in early 1997. He did custom logging development
and consulting even before he wrote these products. Rsyslog draws on
that vast experience and sometimes even on the code.


Based on a discussion I had, I also wrote about the political
argument why it is good to have another strong syslogd besides syslog-ng.
You may want to read it at my blog at "Why
does the world need another syslogd?".

Compatibility notes for rsyslog v5



Compatibility Notes for rsyslog v5


Written by Rainer Gerhards
(2009-07-15)


The changes introduced in rsyslog v5 are numerous, but not very intrusive.
This document describes things to keep in mind when moving from v4 to v5. It 
does not list enhancements nor does it talk about compatibility concerns introduced
by earlier versions (for this, see their respective compatibility documents).

HUP processing


The $HUPisRestart directive is supported by some early v5 versions, but has been removed
in 5.1.3 and above.  That means that restart-type HUP processing is no longer
available. This processing was redundant and had a lot a drawbacks. 
For details, please see the
rsyslog v4 compatibility notes which elaborate
on the reasons and the (few) things you may need to change.

Please note that starting with 5.8.11 HUP will also requery the local hostname.

Queue on-disk format


The queue information file format has been changed. When upgrading from v4 to
v5, make sure that the queue is emptied and no on-disk structure present. We did
not go great length in understanding the old format, as there was too little demand
for that (and it being quite some effort if done right).

Queue Worker Thread Shutdown


Previous rsyslog versions had the capability to "run" on zero queue worker
if no work was required. This was done to save a very limited number of resources. However,
it came at the price of great complexity. In v5, we have decided to let a minium of one
worker run all the time. The additional resource consumption is probably not noticable at
all, however, this enabled us to do some important code cleanups, resulting in faster
and more reliable code (complex code is hard to maintain and error-prone). From the
regular user's point of view, this change should be barely noticable. I am including the
note for expert users, who will notice it in rsyslog debug output and other analysis tools.
So it is no error if each queue in non-direct mode now always runs at least one worker
thread.

gtls Network Stream Driver




gtls Network Stream Driver


This network stream
driver implements a TLS protected transport via the GnuTLS
library.


Available since: 3.19.0 (suggested minimum 3.19.8 and above)


Supported Driver Modes


    

  • 0 - unencrypted trasmission (just like ptcp driver)
    • 

  • 1 - TLS-protected operation
    • 


Note: mode 0 does not provide any benefit over the ptcp driver. This
mode exists for technical reasons, but should not be used. It may be
removed in the future.

Supported Authentication
Modes


    

  • anon
- anonymous authentication as
described in IETF's draft-ietf-syslog-transport-tls-12 Internet draft
    • 

  • x509/fingerprint
- certificate fingerprint authentication as
described in IETF's draft-ietf-syslog-transport-tls-12 Internet draft
    • 

  • x509/certvalid
- certificate validation only
    • 

  • x509/name
- certificate validation and subject name authentication as
described in IETF's draft-ietf-syslog-transport-tls-12 Internet draft

    • 


Note: "anon" does not permit to authenticate the remote peer. As such,
this mode is vulnerable to man in the middle attacks as well as
unauthorized access. It is recommended NOT to use this mode.


x509/certvalid is a nonstandard mode. It validates the remote
peers certificate, but does not check the subject name. This is 
weak authentication that may be useful in scenarios where multiple
devices are deployed and it is sufficient proof of authenticy when
their certificates are signed by the CA the server trusts. This is
better than anon authentication, but still not recommended.
Known Problems


Even in x509/fingerprint mode, both the client and sever
certificate currently must be signed by the same root CA. This is an
artifact of the underlying GnuTLS library and the way we use it. It is
expected that we can resolve this issue in the future.

Oracle Database Output Module



rsyslog module reference


Oracle Database Output Module


Module Name:    omoracle


Author: Luis Fernando Muñoz Mejías <Luis.Fernando.Munoz.Mejias@cern.ch>


Available since: : 4.3.0

Status: : contributed module, not maitained by rsyslog  core authors

Description:


This module provides native support for logging to Oracle
databases. It offers superior performance over the more
generic omlibdbi module.  It also includes
a number of enhancements, most importantly prepared statements and
batching, what provides a big performance improvement.



Note that this module is maintained by its original author. If you need assistance with it,
it is suggested to post questions to the
rsyslog mailing list.

From the header comments of this module:


    This is an output module feeding directly to an Oracle
    database. It uses Oracle Call Interface, a propietary module
    provided by Oracle.

    Selector lines to be used are of this form:

    :omoracle:;TemplateName

    The module gets its configuration via rsyslog $... directives,
    namely:

    $OmoracleDBUser: user name to log in on the database.

    $OmoracleDBPassword: password to log in on the database.

    $OmoracleDB: connection string (an Oracle easy connect or a db
    name as specified by tnsnames.ora)

    $OmoracleBatchSize: Number of elements to send to the DB on each
    transaction.

    $OmoracleStatement: Statement to be prepared and executed in
    batches. Please note that Oracle's prepared statements have their
    placeholders as ':identifier', and this module uses the colon to
    guess how many placeholders there will be.

    All these directives are mandatory. The dbstring can be an Oracle
    easystring or a DB name, as present in the tnsnames.ora file.

    The form of the template is just a list of strings you want
    inserted to the DB, for instance:

    $template TestStmt,"%hostname%%msg%"

    Will provide the arguments to a statement like

    $OmoracleStatement \
        insert into foo(hostname,message)values(:host,:message)

    Also note that identifiers to placeholders are arbitrary. You
    need to define the properties on the template in the correct order
    you want them passed to the statement!

Notes on IPv6 Handling in Rsyslog



Notes on IPv6 Handling in Rsyslog


Rsyslog fully* supports sending and receiving syslog messages via both 
IPv4 and IPv6. IPv6 is natively supported for both UDP and TCP. However, 
there are some options that control handling of IPv6 operations. I thought it is 
is a good idea to elaborate a little about them, so that you can probably find 
your way somewhat easier.


First of all, you can restrict rsyslog to using IPv4 or IPv6 addresses only 
by specifying the -4 or -6 command line option (now guess which one does 
what...). If you do not provide any command line option, rsyslog uses IPv4 and 
IPv6 addresses concurrently. In practice, that means the listener binds to both 
addresses (provided they are configured). When sending syslog messages, rsyslog 
uses IPv4 addresses when the receiver can be reached via IPv4 and IPv6 addresses 
if it can be reached via IPv6. If it can be reached on either IPv4 and v6, 
rsyslog leaves the choice to the socket layer. The important point to know is 
that it uses whatever connectivity is available to reach the destination.


There is one subtle difference between UDP and TCP. With the new 
IPv4/v6 ignorant code, rsyslog has potentially different ways to reach 
destinations. The socket layer returns all of these paths in a sorted array. 
For TCP, rsyslog loops through this array until a successful TCP connect can be 
made. If that happens, the other addresses are ignored and messages are sent via 
the successfully-connected socket.


For UDP, there is no such definite success indicator. Sure, the socket layer 
may detect some errors, but it may not notice other errors (due to the 
unreliable nature of UDP). By default, the UDP sender also tries one entry after 
the other in the sorted array of destination addresses. When a send fails, the 
next address is tried. When the send function finally succeeds, rsyslogd assumes 
the UDP packet has reached its final destination. However, if rsyslogd is 
started with the "-A" (capital A!) was given on the command line, rsyslogd will 
continue to send messages until the end of the destination address array is 
reached. This may result in duplicate messages, but it also provides some 
additional reliability in case a message could not be received. You need to be 
sure about the implications before applying this option. In general, it is NOT 
recommended to use the -A option.


*rsyslog does not support RFC 3195 over IPv6. The reason is that 
the RFC 3195 library, liblogging, 
supports IPv4, only. Currently, there are no plans to update either rsyslog to 
another RFC 3195 stack or update liblogging. There is simply no demand for 3195 
solutions.

Handling a massive syslog database insert rate with Rsyslog

Handling a massive syslog database insert rate with Rsyslog


		
Written by

		Rainer 

		Gerhards (2008-01-31)



Abstract



In this paper, I describe how log massive amounts of
syslog

messages to a database. This HOWTO is currently under development and thus a 
bit brief. Updates are promised ;).



The Intention



Database updates are inherently slow when it comes to storing syslog 
messages. However, there are a number of applications where it is handy to have 
the message inside a database. Rsyslog supports native database writing via 
output plugins. As of this writing, there are plugins available for MySQL an 
PostgreSQL. Maybe additional plugins have become available by the time you read 
this. Be sure to check.


In order to successfully write messages to a database backend, the backend 
must be capable to record messages at the expected average arrival rate. This is 
the rate if you take all messages that can arrive within a day and divide it by 
86400 (the number of seconds per day). Let's say you expect 43,200,000 messages 
per day. That's an average rate of 500 messages per second (mps). Your database 
server MUST be able to handle that amount of message per second on a sustained 
rate. If it doesn't, you either need to add an additional server, lower the 
number of message - or forget about it.


However, this is probably not your peak rate. Let's simply assume your 
systems work only half a day, that's 12 hours (and, yes, I know this is 
unrealistic, but you'll get the point soon). So your average rate is actually 
1,000 mps during work hours and 0 mps during non-work hours. To make matters 
worse, workload is not divided evenly during the day. So you may have peaks of 
up to 10,000mps while at other times the load may go down to maybe just 100mps. 
Peaks may stay well above 2,000mps for a few minutes.


So how the hack you will be able to handle all of this traffic (including the 
peaks) with a database server that is just capable of inserting a maximum of 
500mps?


The key here is buffering. Messages that the database server is not capable 
to handle will be buffered until it is. Of course, that means database insert 
are NOT real-time. If you need real-time inserts, you need to make sure your 
database server can handle traffic at the actual peak rate. But lets assume you 
are OK with some delay.


Buffering is fine. But how about these massive amounts of data? That can't be 
hold in memory, so don't we run out of luck with buffering? The key here is that 
rsyslog can not only buffer in memory but also buffer to disk (this may remind 
you of "spooling" which gets you the right idea). There are several queuing 
modes available, offering differnent throughput. In general, the idea is to 
buffer in memory until the memory buffer is exhausted and switch to 
disk-buffering when needed (and only as long as needed). All of this is handled 
automatically and transparently by rsyslog.


With our above scenario, the disk buffer would build up during the day and 
rsyslog would use the night to drain it. Obviously, this is an extreme example, 
but it shows what can be done. Please note that queue content survies rsyslogd 
restarts, so even a reboot of the system will not cause any message loss.


How To Setup


Frankly, it's quite easy. You just need to do is instruct rsyslog to use a 
disk queue and then configure your action. There is nothing else to do. With the 
following simple config file, you log anything you receive to a MySQL database 
and have buffering applied automatically.



The simple setup above has one drawback: the write database action is 
executed together with all other actions. Typically, local files are also 
written. These local file writes are now bound to the speed of the database 
action. So if the database is down, or threre is a large backlog, local files 
are also not (or late) written.


There is an easy way to avoid this with rsyslog. It involves a 
slightly more complicated setup. In rsyslog, each action can utilize its own 
queue. If so, messages are simply pulled over from the main queue and then the 
action queue handles action processing on its own. This way, main processing and 
the action are de-coupled. In the above example, this means that local file 
writes will happen immediately while the database writes are queued. As a 
side-note, each action can have its own queue, so if you would like to more than 
a single database or send messages reliably to another host, you can do all of 
this on their own queues, de-coupling their processing speeds.


The configuration for the de-coupled database write involves just a few more 
commands:



This is the recommended configuration for this use case. It requires 
rsyslog 3.11.0 or above.


In this example, the main message queue is NOT disk-assisted (there is no 
$MainMsgQueueFileName directive). We still could do that, but have not done it 
because there seems to be no need. The only slow running action is the database 
writer and it has its own queue. So there is no real reason to use a large main 
message queue (except, of course, if you expect *really* heavy traffic bursts).


Note that you can modify a lot of queue performance parameters, but the above
config will get you going with default values. If you consider using this on a real
busy server, it is strongly recommended to invest some time in setting the tuning
parameters to appropriate values.



Feedback requested



I would appreciate feedback on this tutorial. If you have additional ideas, 

comments or find bugs (I *do* bugs - no way... ;)), please

let me know.

UDP spoofing output module (omudpspoof)


rsyslog module reference


UDP spoofing output module (omudpspoof)


Module Name:    omstdout


Authors: Rainer Gerhards <rgerhards@adiscon.com>
and David Lang  <david@lang.hm> 



Available Since: 5.1.3 / v7 config since 7.2.5


Description:


This module is similar to the regular UDP forwarder, but permits to
spoof the sender address. Also, it enables to circle through a number of
source ports.

Important: This module requires root priveleges for its low-level
socket access. As such, the module will not work if rsyslog is configured to
drop privileges.


load() Parameters:


    
	
  • Template [templateName]
    
	sets a non-standard default template for this module.
    • 
	



 


action() parameters:


    
	
  • Target string
    
	Name or IP-Address of the system that shall receive messages. Any resolvable name is fine. 

    • 

	
  • Port [Integer, Default 514]
    
	Name or numerical value of port to use when connecting to target. 

    • 

	
  • Template[Word]
    
	Template to use as message text.
	

    • 

	
  • SourceTemplate [Word]
    
	This is the name of the template that contains a
	numerical IP address that is to be used as the source system IP address.
	While it may often be a constant value, it can be generated as usual via the
	property replacer, as long as it is a valid IPv4 address. If not specified, the
	build-in default template RSYSLOG_omudpspoofDfltSourceTpl is used. This template is defined 
	as follows:
    
	template(name="RSYSLOG_omudpspoofDfltSourceTpl" type="string" string="%fromhost-ip%")
    
	So in essence, the default template spoofs the address of the system the message
	was received from. This is considered the most important use case.
	

    • 

	
  • SourcePortStart[Word]
    
	Specifies the start value for circeling the source ports. Must be less than or
	equal to the end value. Default is 32000.
	

    • 

	
  • SourcePortEnd[Word]
    
	Specifies the ending value for circeling the source ports. Must be less than or
	equal to the start value. Default is 42000.
	

    • 

	
  • mtu[Integer, default 1500]
    
	Maximum MTU supported by the network. Default respects Ethernet and must
	usually not be adjusted. Setting a too-high MTU can lead to message loss,
	too low to excess message fragmentation. Change only if you really know what
	you are doing. This is always given in number of bytes.
	

    • 



pre-v7 Configuration Directives:


    

  • $ActionOMOMUDPSpoofSourceNameTemplate <templatename>
- equivalent to the "sourceTemplate" parameter.

  • $ActionOMUDPSpoofTargetHost <hostname> - equivalent to the "target" parameter.

  • $ActionOMUDPSpoofTargetPort <port> - equivalent to the "target" parameter.

  • $ActionOMUDPSpoofDefaultTemplate <templatename>
- equivalent to the "template" load() parameter.

  • $ActionOMUDPSpoofSourcePortStart <number>
- equivalent to the "SourcePortStart" parameter.

  • $ActionOMUDPSpoofSourcePortEnd <number>
- equivalent to the "SourcePortEnd" parameter.


Caveats/Known Bugs:

    

  • IPv6 is currently not supported. If you need this capability, please let us
know via the rsyslog mailing list.

  • Versions shipped prior to rsyslog 7.2.5 do not support message sizes over 1472 bytes (more
pricesely: over the network-supported MTU). Starting with 7.2.5, those messages will be
fragmented, up to a total upper limit of 64K (induced by UDP). Message sizes over
64K will be truncated. For older versions, messages over 1472 may be totally discarded
or truncated, depending on version and environment.




Config Samples


The following sample forwards all syslog messages in standard form to the
remote server server.example.com. The original sender's address is used. We do not
care about the source port. This example is considered the typical use case for
omudpspoof.





The following sample forwards all syslog messages in unmodified form to the
remote server server.example.com. The sender address 192.0.2.1 with fixed
source port 514 is used.




The following sample is exatly like the previous, but it specifies a larger size
MTU. If, for example, the envrionment supports Jumbo Ethernet frames, increasing the
MTU is useful as it reduces packet fragmentation, which most often is the source of
problems. Note that setting the MTU to a value larger than the local-attached network
supports will lead to send errors and loss of message. So use with care!




Of course, the action can be combined with any type of filter, for
example a tradition PRI filter:



... or any complex expression-based filter:



and of course it can also be combined with as many other actions
as one likes:




Legacy Sample (pre-v7):

remote server server.example.com. The sender address 192.0.2.1 with fixed
source port 514 is used.




The following sample is similar to the previous, but uses as many defaults as possible.
In that sample, a source port in the range 32000..42000 is used. The message is formatted
according to rsyslog's canned default forwarding format. Note that if any parameters
have been changed, the previously set defaults will be used!

mail output module - sending syslog messages via mail
back



Mail Output Module (ommail)


Module Name:    ommail


Available since:    3.17.0


Author: Rainer Gerhards
<rgerhards@adiscon.com>


Description:


This module supports sending syslog messages via mail. Each
syslog message is sent via its own mail. Obviously, you will want to
apply rigorous filtering, otherwise your mailbox (and mail server) will
be heavily spammed. The ommail plugin is primarily meant for alerting
users. As such, it is assume that mails will only be sent in an
extremely limited number of cases.


Please note that ommail is especially well-suited to work in
tandem with imfile to
watch files for the occurence of specific things to be alerted on. So
its scope is far broader than forwarding syslog messages to mail
recipients.

Ommail uses two templates, one for the mail body and one for the
subject line. If neither is provided, a quite meaningless subject line
is used and the mail body will be a syslog message just as if it were
written to a file. It is expected that the users customizes both
messages. In an effort to support cell phones (including SMS gateways),
there is an option to turn off the body part at all. This is considered
to be useful to send a short alert to a pager-like device.



It is highly recommended to use the  "$ActionExecOnlyOnceEveryInterval
<seconds>" directive to limit the amount of
mails that potentially be generated. With it, mails are sent at most in
a <seconds> interval. This may be your life safer. And
remember that an hour has 3,600 seconds, so if you would like to
receive mails at most once every two hours, include a
"$ActionExecOnlyOnceEveryInterval 7200" immediately before the ommail
action. Messages sent more frequently are simpy discarded.

Configuration Directives:


    

  • $ActionMailSMTPServer
    
Name or IP address of the SMTP server to be used. Must currently be
set. The default is 127.0.0.1, the SMTP server on the local machine.
Obviously it is not good to expect one to be present on each machine,
so this value should be specified.
    

    • 

  • $ActionMailSMTPPort
    
Port number or name of the SMTP port to be used. The default is 25, the
standard SMTP port.
    • 

  • $ActionMailFrom
    
The email address used as the senders address. There is no default.
    • 

  • $ActionMailTo
    
The recipient email addresses. There is no default. To specify multiple
recpients, repeat this directive as often as needed. Note: This directive
must be specified for each new action and is automatically reset. 
[Multiple recipients are supported for 3.21.2 and above.]
    • 

  • $ActionMailSubject
    
The name of the template
to be used as the mail subject. If this is not specified, a more or
less meaningless mail subject is generated (we don't tell you the exact
text because that can change - if you want to have something specific,
configure it!).
    • 

  • $ActionMailEnableBody
    
Setting this to "off" permits to exclude the actual message body. This
may be useful for pager-like devices or cell phone SMS messages. The
default is "on", which is appropriate for allmost all cases. Turn it
off only if you know exactly what you do!
    • 


Caveats/Known Bugs:

The current ommail implementation supports SMTP-direct mode
only. In that mode, the plugin talks to the mail server via SMTP
protocol. No other process is involved. This mode offers best
reliability as it is not depending on any external entity except the
mail server. Mail server downtime is acceptable if the action is put
onto its own action queue, so that it may wait for the SMTP server to
come back online. However, the module implements only the bare SMTP
essentials. Most importantly, it does not provide any authentication
capabilities. So your mail server must be configured to accept incoming
mail from ommail without any authentication needs (this may be change
in the future as need arises, but you may also be referred to
sendmail-mode).


In theory, ommail should also offer a mode where it uses the
sendmail utility to send its mail (sendmail-mode).
This is somewhat less reliable (because we depend on an entity we do
not have close control over - sendmail). It also requires dramatically
more system ressources, as we need to load the external process (but
that should be no problem given the expected infrequent number of calls
into this plugin). The big advantage of sendmail mode is that it
supports all the bells and whistles of a full-blown SMTP implementation
and may even work for local delivery without a SMTP server being
present. Sendmail mode will be implemented as need arises. So if you
need it, please drop us a line (I nobody does, sendmail mode will
probably never be implemented).


Sample:


The following sample alerts the operator if the string "hard
disk fatal failure" is present inside a syslog message. The mail server
at mail.example.net is used and the subject shall be "disk problem on
<hostname>". Note how \r\n is included inside the body
text
to create line breaks. A message is sent at most once every 6 hours,
any other messages are silently discarded (or, to be precise, not being
forwarded - they are still being processed by the rest of the
configuration file).





The sample below is the same, but sends mail to two recipients:



A more advanced example plus a discussion on using the email feature
inside a reliable system can be found in Rainer's blogpost
"Why
is native email capability an advantage for a syslogd?"

parser module for "last message repeated n times" (pmlastmsg)


rsyslog module reference


parser module for "last message repeated n times" (pmlastmsg)


Module Name:    pmlastmsg


Module Type:    parser module


Author: Rainer Gerhards <rgerhards@adiscon.com>


Available Since: 5.5.6


Description:


Some syslogds are known to emit severily malformed messages with content
"last message repeated n times". These messages can mess up message reception, as
they lead to wrong interpretation with the standard RFC3164 parser. Rather than
trying to fix this issue in pmrfc3164, we have created a new parser module
specifically for these messages. The reason is that some processing overhead is
involved in processing these messages (they must be recognized) and we would
not like to place this toll on every user but only on those actually in need
of the feature. Note that the performance toll is not large -- but if you expect
a very high message rate with tenthousands of messages per second, you will notice
a difference.

This module should be loaded first inside rsyslog's
parser chain. It processes all those messages that contain a PRI, then none or
some spaces and then the exact text (case-insensitive) "last message repeated n times"
where n must be an integer. All other messages are left untouched.


Please note: this parser module makes it possible that these messages
are properly detected. It does not drop them. If you intend to drop those
messages, you need to use the usual filter logic in combination with the discard
action. As a side-note, please keep on your mind that the sender discarded messages
when the "last message repeated n times" message is emited. You want to consider if
that really is what you intend to happen. If not, go change the sender.


Configuration Directives:


There do not currently exist any configuration directives for this module.

Examples:


This example is the typical use case, where some systems emit malformed
"repeated msg" messages. Other than that, the default RFC5424 and RFC3164 parsers
should be used. Note that when a parser is specified, the default parser chain
is removed, so we need to specify all three parsers. We use this together with the
default ruleset.




Caveats/Known Bugs:

currently none

$RepeatedMsgReduction


Type: global configuration directive


Default: depending on -e


Description:


This directive specifies whether or not repeated messages should be reduced (this is the "Last line repeated n times" feature). If set to on, repeated messages are reduced. If set to off, every message is logged. Please note that this directive overrides the -e command line option. In case -e is given, it is just the default value until the first RepeatedMsgReduction directive is encountered.


This directives affects selector lines until a new directive is specified.

Solaris Input Module (imsolaris)



back


Solaris Input Module


Module Name:    imsolaris


Author: Rainer Gerhards
<rgerhards@adiscon.com>


Description:


Reads local Solaris log messages including the kernel log.


This module is specifically tailored for Solaris. Under Solaris, there
is no special kernel input device. Instead, both kernel messages as well as
messages emitted via syslog() are received from a single source.

This module obeys the Solaris door() mechanism to detect a running syslogd
instance. As such, only one can be active at one time. If it detects another
active intance at startup, the module disables itself, but rsyslog will
continue to run.

Configuration Directives:


    

  • $IMSolarisLogSocketName <name>
    
This is the name of the log socket (stream) to read. If not given, /dev/log
is read.

    • 


Caveats/Known Bugs:

None currently known. For obvious reasons, works on Solaris, only (and compilation
will most probably fail on any other platform).

Sample:


The following sample pulls messages from the default log source

Compatibility notes for rsyslog v3




Compatibility Notes for rsyslog v3


Written by Rainer Gerhards
(2008-03-28)


Rsyslog aims to be a drop-in replacement for sysklogd.
However, version 3 has some considerable enhancements, which lead to
some backward compatibility issues both in regard to sysklogd and
rsyslog v1 and v2. Most of these issues are avoided by default by not
specifying the -c option on the rsyslog command line. That will enable
backwards-compatibility mode. However, please note that things may be
suboptimal in backward compatibility mode, so the advise is to work
through this document, update your rsyslog.conf, remove the no longer
supported startup options and then add -c3 as the first option to the
rsyslog command line. That will enable native mode.


Please note that rsyslogd helps you during that process by
logging appropriate messages about compatibility mode and
backwards-compatibility statemtents automatically generated. You may
want your syslogd log for those. They immediately follow rsyslogd's
startup message.


Inputs


With v2 and below, inputs were automatically started together
with rsyslog. In v3, inputs are optional! They come in the form of
plug-in modules.
At least one input module
must be loaded to make rsyslog do any useful work.
The config file directives doc briefly lists which config statements
are available by which modules.


It is suggested that input modules be loaded in the top part
of the config file. Here is an example, also highlighting the most
important modules:


$ModLoad immark # provides --MARK--
message capability

$ModLoad imudp # provides UDP syslog reception

$ModLoad imtcp # provides TCP syslog reception

$ModLoad imgssapi # provides GSSAPI syslog
reception

$ModLoad imuxsock # provides support for local
system logging (e.g.
via logger command)

$ModLoad imklog # provides kernel logging support (previously done
by rklogd)


Command Line Options


A number of command line options have been removed. New config
file directives have been added for them. The -h and -e option have
been removed even in compatibility mode. They are ignored but an
informative message is logged. Please note that -h was never supported
in v2, but was silently ignored. It disappeared some time ago in the
final v1 builds. It can be replaced by applying proper filtering inside
syslog.conf.


-c option / Compatibility Mode


The -c option is new and tells rsyslogd about the desired
backward compatibility mode. It must always be the first option on the
command line, as it influences processing of the other options. To use
the rsyslog v3 native
interface, specify -c3. To use compatibility mode ,
either do not use -c at all or use -c<vers> where vers is
the
rsyslog version that it shall be compatible to. Use -c0 to be
command-line compatible to sysklogd.
Please note that rsyslogd issues warning messages if the -c3 command line option is not given.
This is to alert you that your are running in compatibility mode.
Compatibility mode interfers with you rsyslog.conf commands and may
cause some undesired side-effects. It is meant to be used with a plain
old rsyslog.conf - if you use new features, things become messy. So the
best advise is to work through this document, convert your options and
config file and then use rsyslog in native mode. In order to aid you in
this process, rsyslog logs every compatibility-mode config file
directive it has generated. So you can simply copy them from your
logfile and paste them to the config.


-e Option

This option is no longer supported, as the "last message repeated n
times" feature is now turned off by default. We changed this default
because this feature is causing a lot of trouble and we need to make it
either go away or change the way it works. For more information, please
see our dedicted forum
thread on "last message repeated n times". This thread also
contains information on how to configure rsyslogd so that it continues
to support this feature (as long as it is not totally removed).

-m Option


The -m command line option is emulated in compatibiltiy mode.
To replace it, use the following config directives (compatibility mode
auto-generates them):


$ModLoad immark

$MarkMessagePeriod 1800 # 30 minutes


-r Option


Is no longer available in native mode. However, it
is
understood in compatibility mode (if no -c option is given). Use the $UDPSeverRun
<port> config file directives. You can now also
set the local address the server should listen to via $UDPServerAddress
<ip> config directive.


The following example configures an UDP syslog server at the
local address 192.0.2.1 on port 514:


$ModLoad imudp

$UDPServerAddress 192.0.2.1 # this MUST be before the $UDPServerRun
directive!

$UDPServerRun 514


"$UDPServerAddress *" means listen on all local interfaces.
This is the default if no directive is specified.


Please note that now multiple listeners are supported. For
example, you can do the following:


$ModLoad imudp

$UDPServerAddress 192.0.2.1 # this MUST be before the $UDPServerRun
directive!

$UDPServerRun 514

$UDPServerAddress * # all local interfaces

$UDPServerRun 1514


These config file settings run two listeners: one
at 192.0.2.1:514 and one on port 1514, which listens on all local
interfaces.


Default port for UDP (and TCP) Servers


Please note that with pre-v3 rsyslogd, a service database
lookup was made when a UDP server was started and no port was
configured. Only if that failed, the IANA default of 514 was used. For
TCP servers, this lookup was never done and 514 always used if no
specific port was configured. For consitency, both TCP and UDP now use
port 514 as default. If a lookup is desired, you need to specify it in
the "Run" directive, e.g. "$UDPServerRun syslog".


klogd


klogd has (finally) been replaced by a loadable input module.
To enable klogd functionality, do


$ModLoad imklog


Note that this can not be handled by the compatibility layer,
as klogd was a separate binary.A limited set of klogd command line
settings is now supported
via rsyslog.conf. That set of configuration directives is to be
expanded. 


Output File Syncing

Rsyslogd tries to keep as compatible to
stock syslogd as possible. As such, it retained stock syslogd's default
of syncing every file write if not specified otherwise (by placing a
dash in front of the output file name). While this was a useful feature
in past days where hardware was much less reliable and UPS seldom, this
no longer is useful in today's worl. Instead, the syncing is a high
performace hit. With it, rsyslogd writes files around 50 *times* slower
than without it. It also affects overall system performance due to the
high IO activity. In rsyslog v3, syncing has been turned off by
default. This is done via a specific configuration directive
"$ActionFileEnableSync on/off" which is off by default. So even if
rsyslogd finds sync selector lines, it ignores them by default. In
order to enable file syncing, the administrator must specify
"$ActionFileEnableSync on" at the top of rsyslog.conf. This ensures
that syncing only happens in some installations where the administrator
actually wanted that (performance-intense) feature. In the fast
majority of cases (if not all), this dramatically increases rsyslogd
performance without any negative effects.

Output File Format


Rsyslog supports high precision RFC 3339 timestamps and puts these into
local log files by default. This is a departure from previous syslogd
behaviour. We decided to sacrify some backward-compatibility in an
effort to provide a better logging solution. Rsyslog has been
supporting the high-precision timestamps for over three years as of
this writing, but nobody used them because they were not default (one
may also assume that most people didn't even know about them). Now, we
are writing the great high-precision time stamps, which greatly aid in
getting the right sequence of logging events. If you do not like that,
you can easily turn them off by placing

$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

right at the start of your rsyslog.conf. This will use the
previous format. Please note that the name is case-sensitive and must
be specificed exactly as shown above. Please also note that you can of
course use any other format of your liking. To do so, simply specify
the template to use or set a new default template via the
$ActionFileDefaultTemplate directive. Keep in mind, though, that
templates must be defined before they are used.
Keep in mind that
when receiving messages from remote hosts, the timestamp is just as
precise as the remote host provided it. In most cases, this means you
will only a receive a standard timestamp with second precision. If
rsyslog is running at the remote end, you can configure it to provide
high-precision timestamps (see below).
Forwarding Format
When
forwarding messages to remote syslog servers, rsyslogd by default uses
the plain old syslog format with second-level resolution inside the
timestamps. We could have made it emit high precision timestamps.
However, that would have broken almost all receivers, including earlier
versions of rsyslog. To avoid this hassle, high-precision timestamps
need to be explicitely enabled. To make this as painless as possible,
rsyslog comes with a canned template that contains everything
necessary.  To enable high-precision timestamps, just use:
$ActionForwardDefaultTemplate RSYSLOG_ForwardFormat # for plain TCP and UDP
$ActionGSSForwardDefaultTemplate RSYSLOG_ForwardFormat # for GSS-API
And, of course, you can always set different forwarding formats by just specifying the right template.
If
you are running in a system with only rsyslog 3.12.5 and above in the
receiver roles, it is suggested to add one (or both) of the above
statements to the top of your rsyslog.conf (but after the $ModLoad's!)
- that will enable you to use the best in timestamp support availble.
Please note that when you use this format with other receivers, they
will probably become pretty confused and not detect the timestamp at
all. In earlier rsyslog versions, for example, that leads to
duplication of timestamp and hostname fields and disables the detection
of the orignal hostname in a relayed/NATed environment. So use the new
format with care. 
Queue Modes for the Main Message Queue


Either "FixedArray" or "LinkedList" is recommended. "Direct"
is available, but should not be used except for a very good reason
("Direct" disables queueing and will potentially lead to message loss
on the input side).

Network Stream Drivers



back


Network Stream Drivers
Network stream drivers are a layer
between various parts of rsyslogd (e.g. the imtcp module) and the
transport layer. They provide sequenced delivery, authentication and
confidentiality to the upper layers. Drivers implement different
capabilities.
 Users need to know about netstream drivers because
they need to configure the proper driver, and proper driver properties,
to achieve desired results (e.g. a TLS-protected syslog transmission).
The following drivers exist:
  • ptcp - the plain tcp network transport (no security)
  • gtls - a secure TLS transport implemented via the GnuTLS library

$omfileForceChown


Type: global configuration directive


Parameter Values: boolean (on/off, yes/no)


Available: 4.7.0+, 5.3.0-5.8.x, NOT available in 5.9.x or higher


Note: this directive has been removed and is no longer available. The
documentation is currently being retained for historical reaons. Expect
it to go away at some later stage as well.

Default: off


Description:


Forces rsyslogd to change the ownership for output files that already exist. Please note
that this tries to fix a potential problem that exists outside the scope of rsyslog. Actually,
it tries to fix invalid ownership/permission settings set by the original file creator.

Rsyslog changes the ownership during initial execution with root privileges. When a privelege
drop is configured, privileges are dropped after the file owner ship is changed. Not that this currently
is a limitation in rsyslog's privilege drop code, which is on the TODO list to be removed. See Caveats
section below for the important implications.

Caveats:


This directive tries to fix a problem that actually is outside the scope of rsyslog. As such,
there are a couple of restrictions and situations in which it will not work. Users are strongly
encouraged to fix their system instead of turning this directive on - it should only be used
as a last resort.

At least in the following scenario, this directive will fail expectedly:

It does not address
the situation that someone changes the ownership *after* rsyslogd has started.
Let's, for example, consider a log rotation script.

    

  • rsyslog is started

  • ownership is changed

  • privileges dropped

  • log rotation (lr) script starts

  • lr removes files

  • lr creates new files with root:adm (or whatever else)

  • lr HUPs rsyslogd

  • rsyslogd closes files

  • rsyslogd tries to open files

  • rsyslogd tries to change ownership --> fail as we are non-root now

  • file open fails



Please note that once the privilege drop code is refactored, this directive will
no longer work, because then privileges will be dropped before any action is performed,
and thus we will no longer be able to chown files that do not belong to the
user rsyslogd is configured to run under.


So expect the directive to go away. It will not
be removed in version 4, but may disappear at any time for any version greater than 4.

Templates - rsyslog.conf


This is a part of the rsyslog.conf - documentation.

Templates


Templates are a key feature of rsyslog. They allow to specify
any
format a user might want. They are also used for dynamic file name
generation. Every output in rsyslog uses templates - this holds true
for files, user messages and so on. The database writer expects its
template to be a proper SQL statement - so this is highly customizable
too. You might ask how does all of this work when no templates at all
are specified. Good question ;) The answer is simple, though. Templates
compatible with the stock syslogd formats are hardcoded into rsyslogd.
So if no template is specified, we use one of these hardcoded
templates. Search for "template_" in syslogd.c and you will find the
hardcoded ones.


Templates are specified by template() statements. They can also be specified
via $Template legacy statements. Note that these are scheduled for removal in
later versions of rsyslog, so it is probably a good idea to avoid them
for new uses.

The template() statement


The template() statement is used to define templates. Note that it is a
static statement, that means all templates are defined when rsyslog
reads the config file. As such, templates are not affected by if-statements
or config nesting.

The basic structure of the template statement is as follows:



template(parameters)



In addition to this simpler syntax, list templates (to be described below)
support an extended syntax:



template(parameters) { list-descriptions }

Each template has a parameter name, which specifies the templates
name, and a parameter type, which specifies the template type. The name
parameter must be unique, and behaviour is unpredictable if it is not. The type
parameter specifies different template types. Different types simply enable
different ways to specify the template content. The template type does not
affect what an (output) plugin can do with it. So use the type that best fits your
needs (from a config writing point of view!). The following types are available:

    

  • list

  • subtree

  • string

  • plugin


The various types are described below.


list


In this case, the template is generated by a list of constant and
variable statements. These follow the template spec in curly braces. This type is
also primarily meant for use with structure-aware outputs, like ommongodb. However,
it also works perfectly with text-based outputs. We recommend to use this mode
if more complex property substitutions needs to be done. In that case, the list-based
template syntax is much clearer than the simple string-based one.

The list template contains the template header (with type="list") and is followed
by constant and property statements, given in curly braces to signify
the template statement they belong to. As the name says, constant statements
describe constant text and property describes property access. There are many options
to property, described further below. Most of these options are used to extract
only partial property contents or to modify the text obtained (like to change its case
to upper or lower case, only).

To grasp the idea, an actual sample is:

template(name="tpl1" type="list") {
	constant(value="Syslog MSG is: '")
	property(name="msg")
	constant(value="', ")
	property(name="timereported" dateFormat="rfc3339" caseConversion="lower")
	constant(value="\n")
	}



This sample is probably primarily targeted at the usual file-based output.




constant statement


This provides a way to specify constant text. The text is used literally. It is
primarily intended for text-based output, so that some constant text can be included. For
example, if a complex template is build for file output, one usually needs to finish it
by a newline, which can be introduced by a constant statement. Here is an actual sample
of that use case from the rsylsog testbench:

template(name="outfmt" type="list") {
	property(name="$!usr!msgnum")
	constant(value="\n")
}

The following escape sequences are recogniced inside the constant text:

    

  • \\ - single backslash

  • \n - LF

  • \ooo - (three octal digits) - represents character with this numerical value (e.g. \101
equals "A"). Note that three
octal digits must be given (in contrast to some languagues, where between one and three are valid).
While we support octal notation, we recommend to use hex notation as this is better known.

  • \xhh - (where h is a hex digit) - represents character with this numerical value (e.g. \x41 
equals "A"). Note that two hexadecimal digits must be given (in contrast to some languagues
where one or two are valid).

  • ... some others ... list needs to be extended



Note: if an unsupported character follows a backslash, this is treated as an error. Behaviour
is unpredictable in this case.

To aid usage of the same template both for text-based outputs and structured ones, constant
text without an "outname" parameter will be ignored when creating the name/value tree
for structured outputs. So if you want to supply some constant text e.g. to mongodb, you must
include an outname, as can be seen here:

template(name="outfmt" type="list") {
	property(name="$!usr!msgnum")
	constant(value="\n" outname="IWantThisInMyDB")
}


The "constant" statement supports the following parameters:

    

  • value - the constant value to use

  • outname - output field name (for structured outputs)





property statement


This statement is used to include property text. It can access all properties. Also,
options permit to specify picking only part of a property or modifying it.
It supports the following parameters:

    

  • name - the name of the property to access

  • outname - output field name (for structured outputs)

  • dateformat - date format to use (only for date-related properties)

  • caseconversion - permits to convert case of the text. supported values are
"lower" and "upper"

  • controlcharacters - specifies how to handle control characters. Supported values are
"escape", which escapes them, "space", which replaces them by a single space, and
"drop", which simply removes them from the string.

  • securepath - used for creating pathnames suitable for use in dynafile templates

  • format - specifiy format on a field basis. Supported values are "csv", for use when
csv-data is generated, "json", which formats proper json content (but without a field
header) and "jsonf", which formats as a complete json field.

  • position.from - obtain substring starting from this position (1 is the first position)

  • position.to - obtain substring up to this position

  • position.relativeToEnd - the from and to position is relative to the end of the string
   instead of the usual start of string. (available since rsyslog v7.3.10)

  • field.number - obtain this field match

  • field.delimiter - decimal value of delimiter character for field extraction

  • regex.expression - expression to use

  • regex.type - either ERE or BRE

  • regex.nomatchmode - what to do if we have no match

  • regex.match - match to use

  • regex.submatch - submatch to use

  • droplastlf - drop a trailing LF, if it is present

  • mandatory - signifies a field as mandatory. If set to "on", this field will always
be present in data passed to structured outputs, even if it is empty. If "off" (the default)
empty fields will not be passed to structured outputs. This is especially useful for outputs
that support dynamic schemas (like ommongodb).

  • spifno1stsp - expert options for RFC3164 template processing





subtree


Available since rsyslog 7.1.4


In this case, the template is generated based on a complete
(CEE) subtree. This type of template is most useful for outputs that know how to
process hierarchical structure, like ommongodb. With that type, the parameter
subtree must be specified, which tells which subtree to use. For example
template(name="tpl1" type="subtree" subtree="$!") includes all CEE data, while
template(name="tpl2" type="subtree" subtree="$!usr!tpl2") includes only the
subtree starting at $!usr!tpl2. The core idea when using this type of template
is that the actual data is prefabricated via set and unset script statements,
and the resulting strucuture is then used inside the template. This method MUST
be used if a complete subtree needs to be placed directly into the 
object's root. With all other template types, only subcontainers can be generated.
Note that subtree type can also be used with text-based outputs, like omfile. HOWEVER,
you do not have any capability to specify constant text, and as such cannot include
line breaks. As a consequence, using this template type for text outputs is usually
only useful for debugging or very special cases (e.g. where the text is interpreted
by a JSON parser later on).

Use case


A typical use case is to first create a custom subtree and then include it into
the template, like in this small example:

set $!usr!tpl2!msg = $msg;

set $!usr!tpl2!dataflow = field($msg, 58, 2);

template(name="tpl2" type="subtree" subtree="$!usr!tpl2") 



Here, we assume that $msg contains various fields, and the data from a field
is to be extracted and stored - together with the message - as field content.

string


This closely resembles the legacy template statement. It
has a mandatory parameter string, which holds the template string to be
applied. A template string is a mix of constant text and replacement variables
(see property replacer). These variables are taken from message or other dynamic
content when the final string to be passed to a plugin is generated. String-based
templates are a great way to specify textual content, especially if no complex
manipulation to properties is necessary. Full details on how to specify template
text can be found below.

Config example:

template(name="tpl3" type="string" string="%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n") 



plugin

In this case, the template is generated by a plugin (which
is then called 
a "strgen" or "string generator"). The format is fix as it is coded. While this
is inflexible, it provides superior performance, and is often used for that
reason (not that "regular" templates are slow - but in very demanding environments
that "last bit" can make a difference). Refer to the plugin's documentation
for further details. For this type, the paramter plugin must be specified and
must contain the name of the plugin as it identifies itself. Note that the 
plugin must be loaded prior to being used inside a template.

Config example:

template(name="tpl4" type="plugin" plugin="mystrgen")




options

The <options> part is optional. It carries options
influencing the template as whole and is part of the template parameters. 
See details below. Be sure NOT to mistake template options with property 
options - the latter ones are processed by the property replacer and 
apply to a SINGLE property, only (and not the whole template).



Template options are case-insensitive. Currently defined are: 


option.sql - format the string suitable for a SQL
statement in MySQL format. This will replace single quotes ("'") and
the backslash character by their backslash-escaped counterpart ("\'"
and "\\") inside each field. Please note that in MySQL configuration,
the NO_BACKSLASH_ESCAPES
mode must be turned off for this format to work (this is the default).


option.stdsql - format the string suitable for a
SQL statement that is to be sent to a standards-compliant sql server.
This will replace single quotes ("'") by two single quotes ("''")
inside each field. You must use stdsql together with MySQL if in MySQL
configuration the
NO_BACKSLASH_ESCAPES is
turned on.


option.json - format the string suitable for a
json statement.
This will replace single quotes ("'") by two single quotes ("''")
inside each field.


At no time, multiple template option should be used. This can cause
unpredictable behaviour and is against all logic.


Either the sql or stdsql 
option must be specified when a template is used
for writing to a database, otherwise injection might occur. Please note
that due to the unfortunate fact that several vendors have violated the
sql standard and introduced their own escape methods, it is impossible
to have a single option doing all the work.  So you yourself
must make sure you are using the right format. If you choose
the wrong one, you are still vulnerable to sql injection.



Please note that the database writer *checks* that the sql option is
present in the template. If it is not present, the write database
action is disabled. This is to guard you against accidental forgetting
it and then becoming vulnerable to SQL injection. The sql option can
also be useful with files - especially if you want to import them into
a database on another machine for performance reasons. However, do NOT
use it if you do not have a real need for it - among others, it takes
some toll on the processing time. Not much, but on a really busy system
you might notice it ;)


The default template for the write to database action has the
sql option set. As we currently support only MySQL and the sql option
matches the default MySQL configuration, this is a good choice.
However, if you have turned on
NO_BACKSLASH_ESCAPES in
your MySQL config, you need to supply a template with the stdsql
option. Otherwise you will become vulnerable to SQL injection. 



To escape:

% = \%

\ = \\ --> '\' is used to escape (as in C)

template (name="TraditionalFormat" type="string" string="%timegenerated% %HOSTNAME% %syslogtag%%msg%\n"





Examples


Standard Template for Writing to Files


template(name="FileFormat" type="list") {
	property(name="timestamp" dateFormat="rfc3339")
	constant(value=" ")
	property(name="hostname")
	constant(value=" ")
	property(name="syslogtag")
	constant(value=" ")
	property(name="msg" spifno1stsp="on" )
	property(name="msg" droplastlf="on" )
	constant(value="\n")
	}



The equivalent string template looks like this:

template(name="FileFormat" type="string"
  string= "%TIMESTAMP% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
)

Note that the template string itself must be on a single line.


Standard Template for Forwarding to a Remote Host (RFC3164 mode)


template(name="ForwardFormat" type="list") {
	constant(value="<")
	property(name="PRI")
	constant(value="<")
	property(name="timestamp" dateFormat="rfc3339")

	property(name="syslogtag" position.from="1" position.to="32")
	constant(value=" ")
	property(name="msg" spifno1stsp="on" )

The equivalent string template looks like this:

template(name="forwardFormat" type="string"
  string="<%PRI%>%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag:1:32%%msg:::sp-if-no-1st-sp%%msg%"
)

Note that the template string itself must be on a single line.


Standard Template for write to the MySQL database


template(name="StdSQLformat" type="list" option.sql="on") {
        constant(value="insert into SystemEvents (Message, Facility, FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag)")
        constant(value=" values ('")
        property(name="msg")
        constant(value="', ")
        property(name="syslogfacility")
        constant(value=", '")
        property(name="hostname")
        constant(value="', ")
        property(name="syslogpriority")
        constant(value=", '")
        property(name="timereported" dateFormat="mysql")
        constant(value="', '")
        property(name="timegenerated" dateFormat="mysql")
        constant(value="', ")
        property(name="iut")
        constant(value=", '")
        property(name="syslogtag")
        constant(value="')")
        }



The equivalent string template looks like this:

template(name="stdSQLformat" type="string" option.sql="on"
  string="insert into SystemEvents (Message, Facility, FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values ('%msg%', %syslogfacility%, '%HOSTNAME%', %syslogpriority%, '%timereported:::date-mysql%', '%timegenerated:::date-mysql%', %iut%, '%syslogtag%')"
)

Note that the template string itself must be on a single line.


legacy format


In pre v6-versions of rsyslog, you need to use the $template 
statement to configure templates. They provide the equivalent to string- and
plugin-based templates. The legacy syntax continous to work in v7, however
we recommend to avoid legacy format for newly written config files. Legacy and
current config statements can coexist within the same config file.

The general format is


$template name,param[,options]


where "name" is the template name and "param" is a single parameter
that specifies template content. The optional "options" part is used to
set template options.

string

The parameter is the same string that with the current-style format you 
specify in the string parameter, for example:


$template strtpl,"PRI: %pri%, MSG: %msg%\n"

Note that list templates are not available in legacy format, so you need
to use complex property replacer constructs to do complex things.


plugin

This is equivalent to the "plugin"-type template directive. Here, the
parameter is the plugin name, with an equal sign prepended. An example
is:


$template plugintpl,=myplugin


Reserved Template Names


Template
names beginning with "RSYSLOG_" are reserved for rsyslog use. Do NOT
use them if, otherwise you may receive a conflict in the future (and
quite unpredictable behaviour). There is a small set of pre-defined
templates that you can use without the need to define it:


    

  • RSYSLOG_TraditionalFileFormat
- the "old style" default log file format with low-precision timestamps
    • 

  • RSYSLOG_FileFormat
- a modern-style logfile format similar to TraditionalFileFormat, buth
with high-precision timestamps and timezone information
    • 

  • RSYSLOG_TraditionalForwardFormat
- the traditional forwarding format with low-precision timestamps. Most
useful if you send messages to other syslogd's or rsyslogd
below
version 3.12.5.
    • 

  • RSYSLOG_SysklogdFileFormat
- sysklogd compatible log file format. If used with options: $SpaceLFOnReceive on;
$EscapeControlCharactersOnReceive off; $DropTrailingLFOnReception off,
the log format will conform to sysklogd log format.
    • 

  • RSYSLOG_ForwardFormat
- a new high-precision forwarding format very similar to the
traditional one, but with high-precision timestamps and timezone
information. Recommended to be used when sending messages to rsyslog
3.12.5 or above.
    • 

  • RSYSLOG_SyslogProtocol23Format
- the format specified in IETF's internet-draft
ietf-syslog-protocol-23, which is assumed to be come the new syslog
standard RFC. This format includes several improvements. The rsyslog
message parser understands this format, so you can use it together with
all relatively recent versions of rsyslog. Other syslogd's may get
hopelessly confused if receiving that format, so check before you use
it. Note that the format is unlikely to change when the final RFC comes
out, but this may happen.
    • 

  • RSYSLOG_DebugFormat
- a special format used for troubleshooting property problems. This format
is meant to be written to a log file. Do not use for production or remote
forwarding.
    • 




The following is legacy documentation soon to be integrated.





Starting with 5.5.6, there are actually two different types of template:

    

  • string based

  • string-generator module based



String-generator module based templates
have been introduced in 5.5.6. They permit a string generator, actually a C "program",
the generate a format. Obviously, it is more work required to code such a generator,
but the reward is speed improvement. If you do not need the ultimate throughput, you
can forget about string generators (so most people never need to know what they are).
You may just be interested in learning that for the most important default formats, 
rsyslog already contains highly optimized string generators and these are called
without any need to configure anything. But if you have written (or purchased) a
string generator module, you need to know how to call it. Each such module has a name,
which you need to know (look it up in the module doc or ask the developer). Let's assume
that "mystrgen" is the module name. Then you can define a template for that strgen
in the following way:


template(name="MyTemplateName" type="plugin" string="mystrgen")


Legacy example:


$template MyTemplateName,=mystrgen

(Of course, you must have first loaded the module via $ModLoad).

The important part is the equal sign in the legacy format: it tells the rsyslog config parser that
no string follows but a strgen module name.

There are no additional parameters but the module name supported. This is because
there is no way to customize anything inside such a "template" other than by
modifying the code of the string generator.


So for most use cases, string-generator module based templates are not
the route to take. Usually, we use string based templates instead.
This is what the rest of the documentation now talks about.


A template consists of a template directive, a name, the
actual template text and optional options. A sample is:


template(name="MyTemplateName" type="string" string="Example: Text %property% some more text\n" options)


Legacy example:


$template MyTemplateName,"\7Text
%property% some more text\n",<options>


The "template" (legacy: $template) is the template directive. It tells rsyslog
that this line contains a template. "MyTemplateName" is the template
name. All
other config lines refer to this name. The text within "string" is the
actual template text. The backslash is an escape character, much as it
is in C. It does all these "cool" things. For example, \7 rings the
bell (this is an ASCII value), \n is a new line. C programmers and perl
coders have the advantage of knowing this, but the set in rsyslog is a
bit restricted currently.



All text in the template is used literally, except for things
within percent signs. These are properties and allow you access to the
contents of the syslog message. Properties are accessed via the
property replacer
(nice name, huh) and it can do cool things, too. For
example, it can pick a substring or do date-specific formatting. More
on this is below, on some lines of the property replacer.






Properties can be accessed by the property
replacer (see there for details).


Templates can be used in the form of a list as well. This has been 
introduced with 6.5.0 The list consists of two parts which are either 
a constant or a property. The constants
are taking the part of "text" that you usually enter in string-based templates. 
The properties stay variable, as they are a substitute for different values of a 
certain type. This type of template is extremely useful for complicated cases,
as it helps you to easily keep an overview over the template. Though, it has
the disadvantage of needing more effort to create it.


Config example:

template(name="MyTemplate" type="list" option.json="off") {
	
constant(value="Test: ")
	
property(name="msg" outname="mymessage")
	
constant(value=" --!!!-- ")
	
property(name="timereported" dateFormat="rfc3339" caseConversion="lower")
	
constant(value="\n")
	
}



First, the general template option will be defined. The values of the template 
itself get defined in the curly brackets. As it can be seen, we have constants
and properties in exchange. Whereas constants will be filled with a value and probably
some options, properties do direct to a property and the options that could be needed
additional format definitions.


We suggest to use separate lines for all constants and properties. This
helps to keep a good overview over the different parts of the template.
Though, writing it in a single line will work, it is much harder to debug
if anything goes wrong with the template. 



Please note that templates can also be
used to generate selector lines with dynamic file names. For
example, if you would like to split syslog messages from different
hosts to different files (one per host), you can define the following
template:


template (name="DynFile" type="string" string="/var/log/system-%HOSTNAME%.log")


Legacy example:


$template
DynFile,"/var/log/system-%HOSTNAME%.log"


This template can then be used when defining an output
selector line. It will result in something like
"/var/log/system-localhost.log"


Legacy String-based Template Samples


This section provides some default templates in legacy format, as used in rsyslog
previous to version 6. Note that this format is still supported, so there is no hard need
to upgrade existing configurations. However, it is strongly recommended that the legacy
constructs are not used when crafting new templates.
Note that each $Template statement is on a single line, but probably broken
accross several lines for display purposes by your browsers. Lines are separated by
empty lines. Keep in mind, that line breaks are important in legacy format.


$template FileFormat,"%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"



$template TraditionalFileFormat,"%TIMESTAMP% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"



$template ForwardFormat,"<%PRI%>%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag:1:32%%msg:::sp-if-no-1st-sp%%msg%"



$template TraditionalForwardFormat,"<%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag:1:32%%msg:::sp-if-no-1st-sp%%msg%"



$template StdSQLFormat,"insert into SystemEvents (Message, Facility, FromHost, Priority, DeviceReportedTime, ReceivedAt, InfoUnitID, SysLogTag) values ('%msg%', %syslogfacility%, '%HOSTNAME%', %syslogpriority%, '%timereported:::date-mysql%', '%timegenerated:::date-mysql%', %iut%, '%syslogtag%')",SQL

nomatch mode - property replacer - rsyslog.con


This is a part of the rsyslog.conf documentation
of the property replacer.


The "nomatch-Mode" specifies which string the property replacer
shall return if a regular expression did not find the search string.. Traditionally,
the string "**NO MATCH**" was returned, but many people complained this was almost never useful.
Still, this mode is support as "DFLT" for legacy configurations.

Three additional and potentially useful modes exist: in one (BLANK) a blank string
is returned. This is probably useful for inserting values into databases where no
value shall be inserted if the expression could not be found.

A similar mode is "ZERO" where the string "0" is returned. This is suitable
for numerical values. A use case may be
that you record a traffic log based on firewall rules and the "bytes transmitted" counter
is extracted via a regular expression. If no "bytes transmitted" counter is available
in the current message, it is probably a good idea to return an empty string, which the
database layer can turn into a zero.

The other mode is "FIELD", in which the complete field is returned. This may be useful
in cases where absense of a match is considered a failure and the message that triggered
it shall be logged.

If in doubt, it is highly suggested to use the
rsyslog online regular expression
checker and generator to see these options in action. With that online tool,
you can craft regular expressions based on samples and try out the different modes.

$ActionExecOnlyWhenPreviousIsSuspended


Type: global configuration directive


Default: off


Description:


This directive allows to specify if actions should always be executed ("off," the default) or only if the previous action is suspended ("on"). This directive works hand-in-hand with the multiple actions per selector feature. It can be used, for example, to create rules that automatically switch destination servers or databases to a (set of) backup(s), if the primary server fails. Note that this feature depends on proper implementation of the suspend feature in the output module. All built-in output modules properly support it (most importantly the database write and the syslog message forwarder).


This selector processes all messages it receives (*.*).  It tries to forward every message to primary-syslog.example.com (via tcp). If it can not reach that server, it tries secondary-1-syslog.example.com, if that fails too, it tries secondary-2-syslog.example.com. If neither of these servers can be connected, the data is stored in /var/log/localbuffer. Please note that the secondaries and the local log buffer are only used if the one before them does not work. So ideally, /var/log/localbuffer will never receive a message. If one of the servers resumes operation, it automatically takes over processing again.


We strongly advise not to use repeated line reduction together with ActionExecOnlyWhenPreviousIsSuspended. It may lead to "interesting" and undesired results (but you can try it if you like).


Sample:


*.* @@primary-syslog.example.com

$ActionExecOnlyWhenPreviousIsSuspended on

&   @@secondary-1-syslog.example.com    # & is used to have more than one action for

&   @@secondary-2-syslog.example.com    # the same selector - the mult-action feature

&   /var/log/localbuffer

$ActionExecOnlyWhenPreviousIsSuspended off # to re-set it for the next selector

sysklogd compatibility


This is a part of the rsyslog.conf documentation.

Back to rsyslog.conf manual

Rsyslog supports standard sysklogd's configuration file format
and extends it. So in general, you can take a "normal" syslog.conf and
use it together with rsyslogd. It will understand everything. However,
to use most of rsyslogd's unique features, you need to add extended
configuration directives.


Rsyslogd supports the classical, selector-based rule lines.
They are still at the heart of it and all actions are initiated via
rule lines.
However, there are ample new directives, either in rsyslog traditional
format (starting with a dollar sign) or in RainerScript format. These
work together with sysklogd statements. A few select statements are
no longer supported and may generate error messages. They are mentioned
in the compatibility notes.

Forwarding Output Module

Forwarding Output Module


Module Name:    omfwd


Author: Rainer Gerhards <rgergards@adiscon.com>


Description:


The omfwd plug-in provides the core functionality of traditional message forwarding via UDP and plain TCP. It is a built-in module that does not need to be loaded. 


 



Global Configuration Directives:


    
	
  • Template [templateName]
    
	sets a non-standard default template for this module.
    • 
	



 


Action specific Configuration Directives:


    
	
  • Target string
    
	Name or IP-Address of the system that shall receive messages. Any resolvable name is fine. 

    • 

	
  • Port [Default 514]
    
	Name or numerical value of port to use when connecting to target. 

    • 

	
  • Protocol udp/tcp [default udp]
    
	Type of protocol to use for forwarding. Note that ``tcp'' means both legacy plain tcp syslog as well as RFC5425-based TCL-encrypted syslog. Which one is selected depends on the protocol drivers set before the action commend. Note that as of 6.3.6, there is no way to specify this within the action itself. 

    • 

	
  • TCP_Framing ``traditional'' or ``octet-counted'' [default traditional]
    
	Framing-Mode to be for forwarding. This affects only TCP-based protocols. It is ignored for UDP. In protocol engineering, ``framing'' means how multiple messages over the same connection are separated. Usually, this is transparent to users. Unfortunately, the early syslog protocol evolved, and so there are cases where users need to specify the framing. The traditional framing is nontransparent. With it, messages are end when a LF (aka ``line break'', ``return'') is encountered, and the next message starts immediately after the LF. If multi-line messages are received, these are essentially broken up into multiple message, usually with all but the first message segment being incorrectly formatted. The octet-counting framing solves this issue. With it, each message is prefixed with the actual message length, so that a receivers knows exactly where the message ends. Multi-line messages cause no problem here. This mode is very close to the method described in RFC5425 for TLS-enabled syslog. Unfortunately, only few syslogd implementations support octet-counted framing. As such, the traditional framing is set as default, even though it has defects. If it is known that the receiver supports octet-counted framing, it is suggested to use that framing mode.  

    • 

	
  • ZipLevel 0..9 [default 0]
    
	Compression level for messages. Rsyslog implements a proprietary capability to zip transmitted messages. Note that compression happens on a message-per-message basis. As such, there is a performance gain only for larger messages. Before compressing a message, rsyslog checks if there is some gain by compression. If so, the message is sent compressed. If not, it is sent uncompressed. As such, it is totally valid that compressed and uncompressed messages are intermixed within a conversation. 
    The compression level is specified via the usual factor of 0 to 9, with 9 being the strongest compression (taking up most processing time) and 0 being no compression at all (taking up no extra processing time). 

    • 

	
  • RebindInterval integer
    
	Permits to specify an interval at which the current connection is broken and re-established. This setting is primarily an aid to load balancers. After the configured number of messages has been transmitted, the current connection is terminated and a new one started. Note that this setting applies to both TCP and UDP traffic. For UDP, the new ``connection'' uses a different source port (ports are cycled and not reused too frequently). This usually is perceived as a ``new connection'' by load balancers, which in turn forward messages to another physical target system. 

    • 

	
  • StreamDriver string
    
	Set the file owner for directories newly created. Please note that this setting does not affect the owner of directories already existing. The parameter is a user name, for which the userid is obtained by rsyslogd during startup processing. Interim changes to the user mapping are not detected.

    • 

	
  • StreamDriverMode integer [default 0]
    
	mode to use with the stream driver (driver-specific)

    • 

	
  • StreamDriverAuthMode string
    
	authentication mode to use with the stream driver. Note that this directive requires TLS netstream drivers. For all others, it will be ignored. (driver-specific).

    • 

	
  • StreamDriverPermittedPeers string
    
	accepted fingerprint (SHA1) or name of remote peer. Note that this directive requires TLS netstream drivers. For all others, it will be ignored. (driver-specific)

    • 

	
  • ResendLastMSGOnReconnect on/off
    
	Permits to resend the last message when a connection is reconnected. This setting affects TCP-based syslog, only. It is most useful for traditional, plain TCP syslog. Using this protocol, it is not always possible to know which messages were successfully transmitted to the receiver when a connection breaks. In many cases, the last message sent is lost. By switching this setting to "yes", rsyslog will always retransmit the last message when a connection is reestablished. This reduces potential message loss, but comes at the price that some messages may be duplicated (what usually is more acceptable). 

    • 
	



Caveats/Known Bugs:
  • None.


Sample:


The following command sends all syslog messages to a remote server via TCP port 10514.








Legacy Configuration Directives:


    
	
  • $ActionForwardDefaultTemplateName string [templatename]
    
	sets a new default template for UDP and plain TCP forwarding action

    • 

	
  • $ActionSendTCPRebindInterval integer
    
	instructs the TCP send action to close and re-open the connection to the remote host every nbr of messages sent. Zero, the default, means that no such processing is done. This directive is useful for use with load-balancers. Note that there is some performance overhead associated with it, so it is advisable to not too often "rebind" the connection (what "too often" actually means depends on your configuration, a rule of thumb is that it should be not be much more often than once per second).

    • 

	
  • $ActionSendUDPRebindInterval integer
    
	instructs the UDP send action to rebind the send socket every nbr of messages sent. Zero, the default, means that no rebind is done. This directive is useful for use with load-balancers.

    • 

	
  • $ActionSendStreamDriver <driver basename>
    
	just like $DefaultNetstreamDriver, but for the specific action 

    • 

	
  • $ActionSendStreamDriverMode <mode> [default 0]
    
	mode to use with the stream driver (driver-specific)

    • 

	
  • $ActionSendStreamDriverAuthMode <mode>
    
	authentication mode to use with the stream driver. Note that this directive requires TLS netstream drivers. For all others, it will be ignored. (driver-specific))

    • 

	
  • $ActionSendStreamDriverPermittedPeers <ID>
    
	accepted fingerprint (SHA1) or name of remote peer. Note that this directive requires TLS netstream drivers. For all others, it will be ignored. (driver-specific) 

    • 

	
  • $ActionSendResendLastMsgOnReconnect on/off [default off]
    
	specifies if the last message is to be resend when a connecition breaks and has been reconnected. May increase reliability, but comes at the risk of message duplication. 

    • 

	
  • $ResetConfigVariables 
    
	Resets all configuration variables to their default value. Any settings made will not be applied to configuration lines following the $ResetConfigVariables. This is a good method to make sure no side-effects exists from previous directives. This directive has no parameters.

    •

The following command sends all syslog messages to a remote server via TCP port 10514.

TCP Syslog Input Module



back to rsyslog module overview


TCP Syslog Input Module


Module Name:    imtcp


Author: Rainer Gerhards <rgerhards@adiscon.com>


Multi-Ruleset Support: since 4.5.0 and 5.1.1

Description:


Provides the ability to receive syslog messages via TCP.
Encryption is natively provided by selecting the approprioate network stream driver and
can also be provided by using stunnel
(an alternative is the use the imgssapi module).



Configuration Directives:


Global Directives:


    

  • AddtlFrameDelimiter <Delimiter>
    
This directive permits to specify an additional frame delimiter for plain tcp syslog.
The industry-standard specifies using the LF character as frame delimiter. Some vendors,
notable Juniper in their NetScreen products, use an invalid frame delimiter, in Juniper's
case the NUL character. This directive permits to specify the ASCII value of the delimiter
in question. Please note that this does not guarantee that all wrong implementations can
be cured with this directive. It is not even a sure fix with all versions of NetScreen,
as I suggest the NUL character is the effect of a (common) coding error and thus will
probably go away at some time in the future. But for the time being, the value 0 can
probably be used to make rsyslog handle NetScreen's invalid syslog/tcp framing.
For additional information, see this
forum thread.

    If this doesn't work for you, please do not blame the rsyslog team. Instead file
a bug report with Juniper!

    Note that a similar, but worse, issue exists with Cisco's IOS implementation. They do
not use any framing at all. This is confirmed from Cisco's side, but there seems to be
very limited interest in fixing this issue. This directive can not fix the Cisco bug.
That would require much more code changes, which I was unable to do so far. Full details
can be found at the Cisco tcp syslog anomaly
page.

  • DisableLFDelimiter <on/off>
    
Industry-strandard plain text tcp syslog uses the LF to delimit syslog frames. However,
some users brought up the case that it may be useful to define a different delimiter and
totally disable LF as a delimiter (the use case named were multi-line messages). This mode
is non-standard and will probably come with a lot of problems. However, as there is need
for it and it is relatively easy to support, we do so. Be sure to turn this setting to
"on" only if you exactly know what you are doing. You may run into all sorts of troubles,
so be prepared to wrangle with that!

  • NotifyOnConnectionClose [on/off]
    
instructs imtcp to emit a message if the remote peer closes a connection.
    
Important: This directive is global to all listeners and must be given right
after loading imtcp, otherwise it may have no effect.
    • 

  • KeepAlive <on/off>
    
enable of disable keep-alive packets at the tcp socket layer. The default is
to disable them.
    • 

  • FlowControl <on/off>
    
This setting specifies whether some message flow control shall be exercised on the
related TCP input. If set to on, messages are handled as "light delayable", which means
the sender is throttled a bit when the queue becomes near-full. This is done in order
to preserve some queue space for inputs that can not throttle (like UDP), but it
may have some undesired effect in some configurations. Still, we consider this as
a useful setting and thus it is the default. To turn the handling off, simply
configure that explicitely.

  • MaxListeners <number>
    
Sets the maximum number of listeners (server ports) supported. Default is 20. This must be set before the first $InputTCPServerRun directive.
    • 

  • MaxSessions <number>
     Sets the maximum number of sessions supported. Default is 200. This must be set before the first $InputTCPServerRun directive
    • 

  • StreamDriver.Mode <number>
    
Sets the driver mode for the currently selected network stream driver. <number> is driver specifc.
    • 

  • StreamDriver.AuthMode <mode-string>
    
Sets the authentication mode for the currently selected network stream driver. <mode-string> is driver specifc.
    • 

  • PermittedPeer <id-string>
    
Sets permitted peer IDs. Only these peers are able to connect to the
listener. <id-string> semantics depend on the currently selected
AuthMode and  network stream driver. PermittedPeer may not be set in anonymous modes.

    PermittedPeer may be set either to a single peer or an array of peers either of type IP or name, depending on the tls certificate.

    Single peer: PermittedPeer="127.0.0.1"

    Array of peers: PermittedPeer=["test1.example.net","10.1.2.3","test2.example.net","..."]
    • 



Action Directives:


    

  • Port <port>
    
Starts a TCP server on selected port
    • 

  • Name <name>
    
Sets a name for the inputname property. If no name is set "imtcp" is used by default. Setting a 
name is not strictly necessary, but can be useful to apply filtering based on which input
the message was received from.

  • Ruleset <ruleset>
    
Binds the listener to a specific ruleset.
    • 

  • SupportOctetCountedFraming <on|off>
    
If set to "on", the legacy octed-counted framing (similar to RFC5425 framing) is
activated. This is the default and should be left unchanged until you know
very well what you do. It may be useful to turn it off, if you know this framing
is not used and some senders emit multi-line messages into the message stream.

    • 

  • RateLimit.Interval [number] - (available since 7.3.1) specifies the rate-limiting
interval in seconds.  Default value is 0, which turns off rate limiting. Set it to a number
of seconds (5 recommended) to activate rate-limiting.

    • 

  • RateLimit.Burst [number] - (available since 7.3.1) specifies the rate-limiting
burst in number of messages. Default is 10,000.

    • 


Caveats/Known Bugs:

    

  • module always binds to all interfaces
    • 

  • can not be loaded together with imgssapi
(which includes the functionality of imtcp)
    • 



Example:


This sets up a TCP server on port 514 and permits it to accept up to 500 connections:





Note that the global parameters (here: max sessions) need to be set when the module is loaded. Otherwise, the parameters will not apply.

rsyslog documentation


RSyslog - Documentation


Rsyslog
is an enhanced syslogd
supporting, among others, MySQL,
PostgreSQL, failover
log destinations, syslog/tcp, fine grain output format
control, high precision timestamps, queued operations and the ability to filter on any message
part.
It is quite compatible to stock sysklogd and can be used as a drop-in
replacement. Its 
advanced features make it suitable for enterprise-class, encryption protected syslog
relay chains while at the same time being very easy to setup for the
novice user. And as we know what enterprise users really need, there are
also  rsyslog
professional services available directly from the source!


Please visit the rsyslog sponsor's page
to honor the project sponsors or become one yourself! We are very grateful for any help towards the
project goals.


This documentation is for version 7.4.4 (v7.4-stable branch) of rsyslog.
Visit the rsyslog status page
to obtain current version information and project status.

If you like rsyslog, you might
want to lend us a helping hand. It doesn't require a lot of
time - even a single mouse click helps. Learn how to help the rsyslog project.
Due to popular demand, there is now a side-by-side comparison
between rsyslog and syslog-ng.


If you are upgrading from rsyslog v2 or stock sysklogd,
be sure to read the rsyslog v3 compatibility notes,
and if you are upgrading from v3, read the
rsyslog v4 compatibility notes,
if you upgrade from v4, read the
rsyslog v5 compatibility notes, and
if you upgrade from v5, read the
rsyslog v6 compatibility notes.
if you upgrade from v6, read the
rsyslog v7 compatibility notes.

Rsyslog will work even
if you do not read the doc, but doing so will definitely improve your experience.

Our rsyslog history
page is for you if you would like to learn a little more
on why there is an rsyslog at all. If you are interested why you should
care about rsyslog at all, you may want to read Rainer's essay on "why
the world needs another syslogd".


Documentation is added continuously. Please note that the
documentation here
matches only the current version of rsyslog. If you use an older
version, be sure to use the doc that came with it.


You can also browse the following online resources:



And don't forget about the rsyslog
mailing list. If you are interested in the "backstage", you
may find
Rainer's
blog an
interesting read (filter on syslog and rsyslog tags).
Or meet Rainer Gerhards at Facebook
or Google+.
If you would like to use rsyslog source code inside your open source project, you can do that without
any restriction as long as your license is GPLv3 compatible. If your license is incompatible to GPLv3,
you may even be still permitted to use rsyslog source code. However, then you need to look at the way
rsyslog is licensed.


Feedback is always welcome, but if you have a support question, please do not
mail Rainer directly (why not?) - use the
rsyslog mailing list
or rsyslog formum instead.

Expressions in rsyslog

back to rsyslog filter conditions

Expressions in rsyslog


Rsyslog supports expressions at a growing number of places. So
far, they are supported for filtering messages.


Expression support is provided by RainerScript. Please see the
RainerScript documentation for more details.


C-like comments (/* some comment */) are supported inside the expression,
but not yet in the rest of the configuration file.

$ActionResumeInterval


Type: global configuration directive


Default: 30


Description:


Sets the ActionResumeInterval for all following actions. The interval 
provided is always in seconds. Thus, multiply by 60 if you need minutes and 
3,600 if you need hours (not recommended).


When an action is suspended (e.g. destination can not be connected), the 
action is resumed for the configured interval. Thereafter, it is retried. If 
multiple retires fail, the interval is automatically extended. This is to 
prevent excessive ressource use for retires. After each 10 retries, the interval 
is extended by itself. To be precise, the actual interval is (numRetries / 10 + 
1) * $ActionResumeInterval. so after the 10th try, it by default is 60 and after 
the 100th try it is 330.


Sample:


$ActionResumeInterval 30

rsyslog queue object



The rsyslog queue object


This page reflects the status as of 2008-01-17. The documentation is still incomplete.
Target audience is developers and users who would like to get an in-depth understanding of
queues as used in rsyslog.


Please note that this document is outdated and does not longer reflect the 
specifics of the queue object. However, I have decided to leave it in the doc 
set, as the overall picture provided still is quite OK. I intend to update this 
document somewhat later when I have reached the "store-and-forward" milestone.


Some definitions


A queue is DA-enabled if it is configured to use disk-assisted mode when 
there is need to. A queue is in DA mode (or DA run mode), when it actually runs 
disk assisted.


Implementation Details


Disk-Assisted Mode


Memory-Type queues may utilize disk-assisted (DA) mode. DA mode is enabled 
whenever a queue file name prefix is provided. This is called DA-enabled mode. 
If DA-enabled, the queue operates as a regular memory queue until a high water 
mark is reached. If that happens, the queue activates disk assistance (called 
"runs disk assisted" or "runs DA" - you can find that often in source file 
comments). To do so, it creates a helper queue instance (the DA queue). At that 
point, there are two queues running - the primary queue's consumer changes to a 
shuffle-to-DA-queue consumer and the original primary consumer is assigned to 
the DA queue. Existing and new messages are spooled to the disk queue, where the 
DA worker takes them from and passes them for execution to the actual consumer. 
In essence, the primary queue has now become a memory buffer for the DA queue. 
The primary queue will be drained until a low water mark is reached. At that 
point, processing is held. New messages enqueued to the primary queue will not 
be processed but kept in memory. Processing resumes when either the high water 
mark is reached again or the DA queue indicates it is empty. If the DA queue is 
empty, it is shut down and processing of the primary queue continues as a 
regular in-memory queue (aka "DA mode is shut down"). The whole thing iterates 
once the high water mark is hit again.


There is one special case: if the primary queue is shut down and could not 
finish processing all messages within the configured timeout periods, the DA 
queue is instantiated to take up the remaining messages. These will be preserved 
and be processed during the next run. During that period, the DA queue runs in 
"enqueue-only" mode and does not execute any consumer. Draining the primary 
queue is typically very fast. If that behaviour is not desired, it can be turned 
of via parameters. In that case, any remaining in-memory messages are lost.


Due to the fact that when running DA two queues work closely together and 
worker threads (including the DA worker) may shut down at any time (due to 
timeout), processing synchronization and startup and shutdown is somewhat 
complex. I'll outline the exact conditions and steps down here. I also do this 
so that I know clearly what to develop to, so please be patient if the 
information is a bit too in-depth ;)


DA Run Mode Initialization


Three cases:


    
	
  1. any time during queueEnqObj() when the high water mark is hit
    2. 
	
  2. at queue startup if there is an on-disk queue present (presence of QI 
	file indicates presence of queue data)
    3. 
	
  3. at queue shutdown if remaining in-memory data needs to be persisted to 
	disk
    4. 



In case 1, the worker pool is running. When switching to DA mode, all 
regular workers are sent termination commands. The DA worker is initiated. 
Regular workers may run in parallel to the DA worker until they terminate. 
Regular workers shall terminate as soon as their current consumer has completed. 
They shall not execute the DA consumer.


In case 2, the worker pool is not yet running and is NOT started. The 
DA worker is initiated.


In case 3, the worker pool is already shut down. The DA worker is 
initiated. The DA queue runs in enqueue-only mode.


In all cases, the DA worker starts up and checks if DA mode is already fully 
initialized. If not, it initializes it, what most importantly means construction 
of the queue.


Then, regular worker processing is carried out. That is, the queue worker 
will wait on empty queue and terminate after an timeout. However, If any message 
is received, the DA consumer is executed. That consumer checks the low water 
mark. If the low water mark is reached, it stops processing until either the 
high water mark is reached again or the DA queue indicates it is empty (there is 
a pthread_cond_t for this synchronization).


In theory, a case-2 startup could lead to the worker becoming inactive 
and terminating while waiting on the primary queue to fill. In practice, this is 
highly unlikely (but only for the main message queue) because rsyslog issues a 
startup message. HOWEVER, we can not rely on that, it would introduce a race. If 
the primary rsyslog thread (the one that issues the message) is scheduled very 
late and there is a low inactivty timeout for queue workers, the queue worker 
may terminate before the startup message is issued. And if the on-disk queue 
holds only a few messages, it may become empty before the DA worker is 
re-initiated again. So it is possible that the DA run mode termination criteria 
occurs while no DA worker is running on the primary queue.


In cases 1 and 3, the DA worker can never become inactive without hitting the 
DA shutdown criteria. In case 1, it either shuffles messages from the 
primary to the DA queue or it waits because it has the hit low water mark. 


In case 3, it always shuffles messages between the queues (because, 
that's the sole purpose of that run). In order for this to happen, the high 
water mark has been set to the value of 1 when DA run mode has been initialized. 
This ensures that the regular logic can be applied to drain the primary queue. 
To prevent a hold due to reaching the low water mark, that mark must be changed 
to 0 before the DA worker starts.


DA Run Mode Shutdown


In essence, DA run mode is terminated when the DA queue is empty and the 
primary worker queue size is below the high water mark. It is also terminated 
when the primary queue is shut down. The decision to switch back to regular 
(non-DA) run mode is typically made by the DA worker. If it switches, the DA 
queue is destructed and the regular worker pool is restarted. In some cases, the 
queue shutdown process may initiate the "switch" (in this case more or less a 
clean shutdown of the DA queue).


One might think that it would be more natural for the DA queue to detect 
being idle and shut down itself. However, there are some issues associated with 
that. Most importantly, all queue worker threads need to be shut down during 
queue destruction. Only after that has happend, final destruction steps can 
happen (else we would have a myriad of races). However, it is the DA queues 
worker thread that detects it is empty (empty queue detection always happens at 
the consumer side and must so). That would lead to the DA queue worker thread to 
initiate DA queue destruction which in turn would lead to that very same thread 
being canceled (because workers must shut down before the queue can be 
destructed). Obviously, this does not work out (and I didn't even mention the 
other issues - so let's forget about it). As such, the thread that enqueues 
messages must destruct the queue - and that is the primary queue's DA worker 
thread.


There are some subleties due to thread synchronization and the fact that the 
DA consumer may not be running (in a case-2 startup). So it is not 
trivial to reliably change the queue back from DA run mode to regular run mode. 
The priority is a clean switch. We accept the fact that there may be situations 
where we cleanly shut down DA run mode, just to re-enable it with the very next 
message being enqueued. While unlikely, this will happen from time to time and 
is considered perfectly legal. We can't predict the future and it would 
introduce too great complexity to try to do something against that (that would 
most probably even lead to worse performance under regular conditions).


The primary queue's DA worker thread may wait at two different places:


    
	
  1. after reaching the low water mark and waiting for either high water or 
	DA queue empty
    2. 
	
  2. at the regular pthread_cond_wait() on an empty primary queue
    3. 



Case 2 is unlikely, but may happen (see info above on a case 2 startup).


The DA worker may also not wait at all, because it is actively 
executing and shuffeling messages between the queues. In that case, however, the 
program flow passes both of the two wait conditions but simply does not wait.


Finally, the DA worker may be inactive (again, with a case-2 startup). 
In that case no work(er) at all is executed. Most importantly, without the DA 
worker being active, nobody will ever detect the need to change back to regular 
mode. If we have this situation, the very next message enqueued will cause the 
switch, because then the DA run mode shutdown criteria is met. However, it may 
take close to eternal for this message to arrive. During that time, disk and 
memory resources for the DA queue remain allocated. This also leaves processing 
in a sub-optimal state and it may take longer than necessary to switch back to 
regular queue mode when a message burst happens. In extreme cases, this could 
even lead to shutdown of DA run mode, which takes so long that the high water 
mark is passed and DA run mode is immediately re-initialized - while with an 
immediate switch, the message burst may have been able to be processed by the 
in-memory queue without DA support.


So in short, it is desirable switch to regular run mode as soon as possible. 
To do this, we need an active DA worker. The easy solution is to initiate DA 
worker startup from the DA queue's worker once it detects empty condition. To do 
so, the DA queue's worker must call into a "DA worker startup initiation" 
routine inside the main queue. As a reminder, the DA worker will most probably 
not receive the "DA queue empty" signal in that case, because it will be long 
sent (in most cases) before the DA worker even waits for it. So it is vital 
that DA run mode termination checks be done in the DA worker before it goes into 
any wait condition.


Please note that the "DA worker startup initiation" routine may be 
called concurrently from multiple initiators. To prevent a race, it must be 
guarded by the queue mutex and return without any action (and no error 
code!) if the DA worker is already initiated.


All other cases can be handled by checking the termination criteria 
immediately at the start of the worker and then once again for each run. The 
logic follows this simplified flow diagram:






Some of the more subtle aspects of worker processing (e.g. enqueue thread 
signaling and other fine things) have been left out in order to get the big 
picture. What is called "check DA mode switchback..." right after "worker init" 
is actually a check for the worker's termination criteria. Typically, the 
worker termination criteria is a shutdown request. However, for a DA 
worker, termination is also requested if the queue size is below the high water 
mark AND the DA queue is empty. There is also a third termination criteria 
and it is not even on the chart: that is the inactivity timeout, which exists in 
all modes. Note that while the inactivity timeout shuts down a thread, it 
logically does not terminate the worker pool (or DA worker): workers are 
restarted on an as-needed basis. However, inactivity timeouts are very important 
because they require us to restart workers in some situations where we may 
expect a running one. So always keep them on your mind.


Queue Destruction


Now let's consider the case of destruction of the primary queue. During 
destruction, our focus is on loosing as few messages as possible. If the 
queue is not DA-enabled, there is nothing but the configured timeouts to handle 
that situation. However, with a DA-enabled queue there are more options.


If the queue is DA-enabled, it may be configured to persist messages to 
disk before it is terminated. In that case, loss of messages never occurs 
(at the price of a potentially lengthy shutdown). Even if that setting is not 
applied, the queue should drain as many messages as possible to the disk. For 
that reason, it makes no sense to wait on a low water mark. Also, if the queue 
is already in DA run mode, it does not make any sense to switch back to regular 
run mode during termination and then try to process some messages via the 
regular consumer. It is much more appropriate the try completely drain the queue 
during the remaining timeout period. For the same reason, it is preferred that 
no new consumers be activated (via the DA queue's worker), as they only cost 
valuable CPU cycles and, more importantly, would potentially be long(er)-running 
and possibly be needed to be cancelled. To prevent all of that, queue 
parameters are changed for DA-enabled queues: the high water mark is to 1 
and the low water mark to 0 on the primary queue. The DA queue is commanded to 
run in enqueue-only mode. If the primary queue is configured to persist 
messages to disk before it is terminated, its SHUTDOWN timeout is changed to 
to eternal. These parameters will cause the queue to drain as much as possible 
to disk (and they may cause a case 3 DA run mode initiation). Please note that 
once the primary queue has been drained, the DA queue's worker will 
automatically switch back to regular (non-DA) run mode. It must be ensured 
that no worker cancellation occurs during that switchback. Please note that 
the queue may not switch back to regular run mode if it is not configured to 
persist messages to disk before it is terminated. In order to apply the new 
parameters, worker threads must be awakened. Remember we may not be in DA 
run mode at this stage. In that case, the regular workers must be awakened, which 
then will switch to DA run mode. No worker may be active, in that case one must 
be initiated. If in DA run mode and the DA worker is inactive, the  "DA 
worker startup initiation" must be called to activate it. That routine 
ensures only one DA worker is started even with multiple concurrent callers - 
this may be the case here. The DA queue's worker may have requested DA worker 
startup in order to terminate on empty queue (which will probably not be honored 
as we have changed the low water mark).


After all this is done, the queue destructor requests termination of the 
queue's worker threads. It will use the normal timeouts and potentially cancel 
too-long running worker threads. The shutdown process must ensure that all 
workers reach running state before they are commanded to terminate. 
Otherwise it may run into a race condition that could lead to a false shutdown 
with workers running asynchronously. As a few workers may have just been started 
to initialize (to apply new parameter settings), the probability for this race 
condition is extremely high, especially on single-CPU systems.


After all workers have been shut down (or cancelled), the queue may still be 
in DA run mode. If so, this must be terminated, which now can simply be done by 
destructing the DA queue object. This is not a real switchback to regular run 
mode, but that doesn't matter because the queue object will soon be gone away.


Finally, the queue is mostly shut down and ready to be actually destructed. 
As a last try, the queuePersists() entry point is called. It is used to persists 
a non-DA-enabled queue in whatever way is possible for that queue. There may be 
no implementation for the specific queue type. Please note that this is not just 
a theoretical construct. This is an extremely important code path when the DA 
queue itself is destructed. Remember that it is a queue object in its own right. 
The DA queue is obviously not DA-enabled, so it calls into queuePersists() 
during its destruction - this is what enables us to persist the disk queue!


After that point, left over queue resources (mutexes, dynamic memory, ...) 
are freed and the queue object is actually destructed.

TLS-protected syslog: recommended scenario




Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-06-17)




Overview


This document describes a secure way to set up rsyslog TLS. A secure logging
environment requires more than just encrypting the transmission channel. This document
provides one possible way to create such a secure system.

Rsyslog's TLS authentication can be used very flexible and thus supports a 
wide range of security policies. This section tries to give some advise on a 
scenario that works well for many environments. However, it may not be suitable 
for you - please assess you security needs before using the recommendations 
below. Do not blame us if it doesn't provide what you need ;)


Our policy offers these security benefits:


    
	
  • syslog messages are encrypted while traveling on the wire
    • 
	
  • the syslog sender authenticates to the syslog receiver; thus, the 
	receiver knows who is talking to it
    • 
	
  • the syslog receiver authenticates to the syslog sender; thus, the sender 
	can check if it indeed is sending to the expected receiver
    • 
	
  • the mutual authentication prevents man-in-the-middle attacks
    • 



Our secrity goals are achived via public/private key security. As such, it is 
vital that private keys are well protected and not accessible to third parties. 




If private keys have become known to third parties, the system does not provide 
any security at all. Also, our solution bases on X.509 certificates and a (very 
limited) chain of trust. We have one instance (the CA) that issues all machine 
certificates. The machine certificate indentifies a particular machine. hile in 
theory (and practice), there could be several "sub-CA" that issues machine 
certificates for a specific adminitrative domain, we do not include this in our 
"simple yet secure" setup. If you intend to use this, rsyslog supports it, but 
then you need to dig a bit more into the documentation (or use the forum to ask). 
In general, if you depart from our simple model, you should have good reasons 
for doing so and know quite well what you are doing - otherwise you may 
compromise your system security.


Please note that security never comes without effort. In the scenario 
described here, we have limited the effort as much as possible. What remains is 
some setup work for the central CA, the certificate setup for each machine as 
well as a few configuration commands that need to be applied to all of them. 
Proably the most important limiting factor in our setup is that all senders and 
receivers must support IETF's syslog-transport-tls standard (which is not 
finalized yet). We use mandatory-to-implement technology, yet you may have 
trouble finding all required features in some implementations. More often, 
unfortunately, you will find that an implementation does not support the 
upcoming IETF standard at all - especially in the "early days" (starting May 
2008) when rsyslog is the only implementation of said standard.


Fortunately, rsyslog supports allmost every protocol that is out there in the 
syslog world. So in cases where transport-tls is not available on a sender, we 
recommend to use rsyslog as the initial relay. In that mode, the not-capabe 
sender sends to rsyslog via another protocol, which then relays the message via 
transport-tls to either another interim relay or the final destination (which, 
of course, must by transport-tls capable). In such a scenario, it is best to try 
see what the sender support. Maybe it is possible to use industry-standard plain 
tcp syslog with it. Often you can even combine it with stunnel, which then, too, 
enables a secure delivery to the first rsyslog relay. If all of that is not 
possible, you can (and often must...) resort to UDP. Even though this is now 
lossy and insecure, this is better than not having the ability to listen to that 
device at all. It may even be reasonale secure if the uncapable sender and the 
first rsyslog relay communicate via a private channel, e.g. a dedicated network 
link.


One final word of caution: transport-tls protects the connection between the 
sender and the receiver. It does not necessarily protect against attacks that 
are present in the message itself. Especially in a relay environment, the 
message may have been originated from a malicious system, which placed invalid 
hostnames and/or other content into it. If there is no provisioning against such 
things, these records may show up in the receivers' repository. -transport-tls 
does not protect against this (but it may help, properly used). Keep in mind 
that syslog-transport-tls provides hop-by-hop security. It does not provide 
end-to-end security and it does not authenticate the message itself (just the 
last sender).

Rsyslog Debug Support


Rsyslog Debug Support



Rsyslog provides a number of debug aides. Some of them are activated by
adding the --enable-rtinst ./configure option ("rtinst" means runtime
instrumentation). Turning debugging on obviously costs some performance
(in some cases considerable).



This is document is just being created and thus terse.


Signals supported


SIGUSR1 - turns debug messages on and off. Note that for this
signal to work, rsyslogd must be running with debugging enabled, either
via the -d command line switch or the environment options specified below.
It is not required that rsyslog was compiled with debugging enabled
(but depending on the settings this may lead to better debug info).

SIGUSR2 - outputs debug information (including active threads
and a call stack) for the state when SIGUSR2 was received. This is a
one-time output. Can be sent as often as the user likes.

Note: this signal may go away in later releases and may
be replaced by something else.


Environment Variables


There are two environment variables that set several debug settings:

    

  • The "RSYSLOG_DEBUGLOG" (sample:  RSYSLOG_DEBUGLOG="/path/to/debuglog/")
writes (allmost)
all debug message to the specified log file in addition to stdout. Some
system messages (e.g. segfault or abort message) are not written to the
file as we can not capture them.

  • Runtime debug support is controlled by "RSYSLOG_DEBUG".

    The "RSYSLOG_DEBUG" environment variable contains an option string with the following
options possible (all are case insensitive):
    

      

    • LogFuncFlow - print out the logical flow of functions (entering and exiting them)
      • 

    • FileTrace - specifies which files to trace LogFuncFlow. If not
set (the default), a LogFuncFlow trace is provided for all files. Set
to limit it to the files specified. FileTrace may be specified multiple
times, one file each (e.g. export RSYSLOG_DEBUG="LogFuncFlow
FileTrace=vm.c FileTrace=expr.c"
      • 

    • PrintFuncDB - print the content of the debug function database whenever debug information is printed (e.g. abort case)!
      • 

    • PrintAllDebugInfoOnExit - print all debug information immediately before rsyslogd exits (currently not implemented!)
      • 

    • PrintMutexAction - print mutex action as it happens. Useful for finding deadlocks and such.
      • 

    • NoLogTimeStamp - do not prefix log lines with a timestamp (default is to do that).
      • 

    • NoStdOut - do not emit debug messages to stdout. If RSYSLOG_DEBUGLOG is not set, this means no messages will be displayed at all.
      • 

    • Debug - if present, turns on the debug system and enables debug output

    • DebugOnDemand - if present, turns on the debug system but does not enable
debug output itself. You need to send SIGUSR1 to turn it on when desired.

    • OutputTidToStderr - if present, makes rsyslog output information about
the thread id (tid) of newly create processesto stderr. Note that not necessarily
all new threads are reported (depends on the code, e.g. of plugins). This is
only available under Linux. This usually does NOT work when privileges have
been dropped (that's not a bug, but the way it is).

    • help - display a very short list of commands - hopefully a life saver if you can't access the documentation...
      • 

    

    Individual options are separated by spaces.
    



Why Environment Variables?


You may ask why we use environment variables for debug-system parameters and not
the usual rsyslog.conf configuration commands. After all, environment variables force one
to change distro-specific configuration files, whereas regular configuration directives
would fit nicely into the one central rsyslog.conf.

The problem here is that many settings of the debug system must be initialized 
before the full rsyslog engine starts up. At that point, there is no such thing like
rsyslog.conf or the objects needed to process it present in an running instance.
And even if we would enable to change settings some time later, that would mean that
we can not correctly monitor (and debug) the initial startup phase of rsyslogd. What
makes matters worse is that during this startup phase (and never again later!) some
of the base debug structure needs to be created, at least if the build is
configured for that (many of these things only happen in --enable-rtinst mode). So
if we do not initialize the debug system before actually startig up the
rsyslog core, we get a number of data structures wrong.

For these reasons, we utilize environment variables to initialize and configure
the debugging system. We understand this may be somewhat painful, but now you know
there are at least some good reasons for doing so.

HOWEVER, if you have a too hard time to set debug instructions using the environment
variables, there is a cure, described in the next paragraph.


Enabling Debug via rsyslog.conf


As described in the previous paragraph, enabling debug via rsyslog.conf
may not be perfect for some debugging needs, but basic debug output will work - and
that is what most often is requried. There are limited options available, but these
cover the most important use cases.

Debug processing is done via legacy config statements. There currently
is no plan to move these over to the v6+ config system. Availabe settings are

    

  • $DebugFile <filename> - sets the debug file name

  • $DebugLevel <0|1|2> - sets the respective debug level, where
0 means debug off, 1 is debug on demand activated (but debug mode off) 
and 2 is full debug mode.



Note that in theory it is forbidden to specify these parameters more
than once. However, we do not enforce that and if it happens results
are undefined.


Getting debug information from a running Instance


It is possible to obtain debugging information from a running instance, but this requires
some setup. We assume that the instance runs in the background, so debug output to
stdout is not desired. As such, all debug information needs to go into a log file.

To create this setup, you need to

    

  • point the RSYSLOG_DEBUGLOG environment variable to a file that is accessible
during the while runtime (we strongly suggest a file in the local file system!)

  • set RSYSLOG_DEBUG at least to "DebugOnDeman NoStdOut"

  • make sure these environment variables are set in the correct (distro-specifc)
startup script if you do not run rsyslogd interactively



These settings enable the capability to react to SIGUSR1. The signal will toggle
debug status when received. So send it one to turn debug loggin on, and send it again
to turn debug logging off again. The third time it will be turned on again ... and so on.

On a typical system, you can signal rsyslogd as follows:

kill -USR1 `cat /var/run/rsyslogd.pid`


Important: there are backticks around the "cat"-command. If you use the regular
quote it won't work. The debug log will show whether debug logging has been turned
on or off. There is no other indication of the status.

Note: running with DebugOnDemand by itself does in practice not have any performance
toll. However, switching debug logging on has a severe performance toll. Also, debug
logging synchronizes much of the code, removing a lot of concurrency and thus
potential race conditions. As such, the very same running instance may behave
very differently with debug logging turned on vs. off. The on-demand debug log
functionality is considered to be very valuable to analyze hard-to-find bugs that
only manifest after a long runtime. Turning debug logging on a failing instance
may reveal the cause of the failure. However, depending on the failure, debug logging
may not even be successfully be turned on. Also note that with this rsyslog version we cannot 
obtain any debug information on events that happened before debug logging was
turned on.

If an instance hangs, it is possible to obtain some useful information about the current
threads and their calling stack by sending SIGUSR2. However, the usefulness of that
information is very much depending on rsyslog compile-time settings, must importantly
the --enable-rtinst configure flag. Note that activating this option causes additional overhead
and slows down rsyslgod considerable. So if you do that, you need to check if it is
capable to handle the workload. Also, threading behavior is modified by the
runtime instrumentation.

Sending SIGUSR2 writes new process state information to the log file each time 
it is sent. So it may be useful to do that from time to time. It probably is most 
useful if the process seems to hang, in which case it may (may!) be able to output
some diagnostic information on the current processing state. In that case, turning
on the mutex debugging options (see above) is probably useful.

Interpreting the Logs


Debug logs are primarily meant for rsyslog developers. But they may still provide valuable
information to users. Just be warned that logs sometimes contains informaton the looks like
an error, but actually is none. We put a lot of extra information into the logs, and there
are some cases where it is OK for an error to happen, we just wanted to record it inside
the log. The code handles many cases automatically. So, in short, the log may not make sense to
you, but it (hopefully) makes sense to a developer. Note that we developers often need
many lines of the log file, it is relatively rare that a problem can be diagnosed by
looking at just a couple of (hundered) log records.

Security Risks


The debug log will reveal potentially sensible information, including user accounts and
passwords, to anyone able to read the log file. As such, it is recommended to properly
guard access to the log file. Also, an instance running with debug log enabled runs much
slower than one without. An attacker may use this to place carry out a denial-of-service
attack or try to hide some information from the log file. As such, it is suggested to
enable DebugOnDemand mode only for a reason. Note that when no debug mode is enabled,
SIGUSR1 and SIGUSR2 are completely ignored.

When running in any of the debug modes (including on demand mode), an interactive 
instance of rsyslogd can be aborted by pressing ctl-c.

Using php-syslog-ng with rsyslog




Using php-syslog-ng with rsyslog

		
Written by
		Rainer 
		Gerhards (2005-08-04)


Note: it has been reported that this guide is somewhat outdated. Please 
use with care. Also, please note that rsyslog's "native" web frontend is
phpLogCon, which provides best integration
and a lot of extra functionality.


Abstract


In this paper, I describe how to use
php-syslog-ng with
rsyslogd.  Php-syslog-ng is a 
popular web interface to syslog data. Its name stem from the fact that it 
usually picks up its data from a database created by
syslog-ng and some 
helper scripts. However, there is nothing syslog-ng specific in the database. 
With rsyslogd's high customizability, it is easy to write to a syslog-ng like 
schema. I will tell you how to do this, enabling you to use php-syslog-ng as a 
front-end for rsyslogd - or save the hassle with syslog-ng database 
configuration and simply go ahead and use rsyslogd instead.


Overall System Setup


The setup is pretty straightforward. Basically, php-syslog-ng's interface to 
the syslogd is the database. We use the schema that php-syslog-ng expects and 
make rsyslogd write to it in its format. Because of this, php-syslog-ng does not 
even know there is no syslog-ng present.


Setting up the system


For php-syslog-ng, you can follow its usual setup instructions. Just skip any 
steps refering to configure syslog-ng. Make sure you create the database schema 
in MySQL. As of this writing, the expected schema can be created via this script:



	CREATE DATABASE syslog

	!

	USE syslog

	!

	CREATE TABLE logs (

	host varchar(32) default NULL,

	facility varchar(10) default NULL,

	priority varchar(10) default NULL,

	level varchar(10) default NULL,

	tag varchar(10) default NULL,

	date date default NULL,

	time time default NULL,

	program varchar(15) default NULL,

	msg text,

	seq int(10) unsigned NOT NULL auto_increment,

	PRIMARY KEY (seq),

	KEY host (host),

	KEY seq (seq),

	KEY program (program),

	KEY time (time),

	KEY date (date),

	KEY priority (priority),

	KEY facility (facility)

	) TYPE=MyISAM;



Please note that at the time you are reading this paper, the schema might have changed. 
Check for any differences. As we customize rsyslogd to the schema, it is vital 
to have the correct one. If this paper is outdated,
let me know so that I can fix it.


Once this schema is created, we simply instruct rsyslogd to store received 
data in it. I wont go into too much detail here. If you are interested in some 
more details, you might find my paper "Writing 
syslog messages to MySQL" worth reading. For this article, we simply modify
rsyslog.conf so that it writes to the database. 
That is easy. Just these two lines are needed:



	$template syslog-ng,"insert into logs(host, facility, priority, tag, date, 
	time, msg) values ('%HOSTNAME%', %syslogfacility%, %syslogpriority%, 
	'%syslogtag%',  '%timereported:::date-mysql%', '%timereported:::date-mysql%', 
	'%msg%')", SQL 

	*.*             >mysql-server,syslog,user,pass;syslog-ng
	



These are just two lines. I have color-coded them so that you see what 
belongs together (the colors have no other meaning). The green line is the 
actual SQL statement being used to take care of the syslog-ng schema. Rsyslogd 
allows you to fully control the statement sent to the database. This allows you 
to write to any database format, including your homegrown one (if you so desire). 
Please note that there is a small inefficiency in our current usage: the
	'%timereported:::date-mysql%'  
property is used for both the time and the date (if you wonder about what all 
these funny characters mean, see the rsyslogd 
property replacer manual) . We could have extracted just the date and time 
parts of the respective properties. However, this is more complicated and also 
adds processing time to rsyslogd's processing (substrings must be extracted). So we take a full mysql-formatted timestamp and supply it to MySQL. The sql engine in turn 
discards the unneeded part. It works pretty well. As of my understanding, the 
inefficiency of discarding the unneeded part in MySQL is lower than the 
effciency gain from using the full timestamp in rsyslogd. So it is most probably 
the best solution.


Please note that rsyslogd knows two different timestamp properties: one is 
timereported, used here. It is the timestamp from the message itself. Sometimes 
that is a good choice, in other cases not. It depends on your environment. The other one is the timegenerated 
property. This is the time when rsyslogd received the message. For obvious 
reasons, that timestamp is consistent, even when your devices are in multiple 
time zones or their clocks are off. However, it is not "the real thing". It's 
your choice which one you prefer. If you prefer timegenerated ... simply use it 
;)


The line in red tells rsyslogd which messages to log and where to store it. 
The "*.*" selects all messages. You can use standard syslog selector line filters here if 
you do not like to see everything in your database. The ">" tells 
rsyslogd that a MySQL connection 
must be established. Then, "mysql-server" is the name or IP address of the 
server machine, "syslog" is the database name (default from the schema) and "user" 
and "pass" are the logon credentials. Use a user with low privileges, insert into the 
logs table is sufficient. "syslog-ng" is the template name and tells rsyslogd to 
use the SQL statement shown above.


Once you have made the changes, all you need to do is restart
rsyslogd. Then, you should see syslog messages flow into your database - and 
show up in php-syslog-ng.


Conclusion


With minumal effort, you can use php-syslog-ng together with rsyslogd. For 
those unfamiliar with syslog-ng, this configuration is probably easier to set up 
then switching to syslog-ng. For existing rsyslogd users, php-syslog-ng might be a nice 
add-on to their logging infrastructure.


Please note that the MonitorWare family (to which rsyslog belongs) also 
offers a web-interface: phpLogCon.
From my point of view, obviously, phpLogCon is the more natural choice for a web interface
to be used together with rsyslog. It also offers superb functionality and provides,
for example,native display of Windows event log entries.
I have set up a demo server., 
You can have a peek at it 
without installing anything.

Writing syslog Data to MySQL




About rsyslog Modules


Written by
Rainer Gerhards (2007-07-28)


This document is incomplete. The module interface is 
also quite incomplete and under development. Do not currently use it! 
You may want to visit Rainer's blog 
to learn what's going on.


Overview


In theory, modules provide input and output, among other functions, in 
rsyslog. In practice, modules are only utilized for output in the current 
release. The module interface is not yet completed and a moving target. We do 
not recommend to write a module based on the current specification. If you do, 
please be prepared that future released of rsyslog will probably break your 
module. 


A goal of modularization is to provide an easy to use plug-in interface. 
However, this goal is not yet reached and all modules must be statically linked.


Module "generation"


There is a lot of plumbing that is always the same in all modules. For 
example, the interface definitions, answering function pointer queries and such. 
To get rid of these laborious things, I generate most of them automatically from 
a single file. This file is named module-template.h. It also contains the 
current best description of the interface "specification".


One thing that can also be achieved with it is the capability to cope with a 
rapidly changing interface specification. The module interface is evolving. 
Currently, it is far from being finished. As I moved the monolithic code to 
modules, I needed (and still need) to make many "non-clean" code hacks, just to 
get it working. These things are now gradually being removed. However, this 
requires frequent changes to the interfaces, as things move in and out while 
working towards a clean interface. All the interim is necessary to reach the 
goal. This volatility of specifications is the number one reasons I currently 
advise against implementing your own modules (hint: if you do, be sure to use 
module-template.h and be prepared to fix newly appearing and disappearing data 
elements).


Naming Conventions


Source


Output modules, and only output modules, should start with a file name of 
"om" (e.g. "omfile.c", "omshell.c"). Similarly, input modules will use "im" and 
filter modules "fm". The third character shall not be a hyphen.


Module Security


Modules are directly loaded into rsyslog's address space. As such, any module 
is provided a big level of trust. Please note that further module interfaces 
might provide a way to load a module into an isolated address space. This, 
however, is far from being completed. So the number one rule about module 
security is to run only code that you know you can trust.


To minimize the security risks associated with modules, rsyslog provides only 
the most minimalistic access to data structures to its modules. For that reason, 
the output modules do not receive any direct pointers to the selector_t 
structure, the syslogd action structures and - most importantly - the msg 
structure itself. Access to these structures would enable modules to access data 
that is none of their business, creating a potential security weakness.


Not having access to these structures also simplifies further queueing and 
error handling cases. As we do not need to provide e.g. full access to the msg 
object itself, we do not need to serialize and cache it. Instead, strings needed 
by the module are created by syslogd and then the final result is provided to 
the module. That, for example, means that in a queued case $NOW is the actual 
timestamp of when the message was processed, which may be even days before it 
being dequeued. Think about it: If we wouldn't cache the resulting string, $NOW 
would be the actual date if the action were suspended and messages queued for 
some time. That could potentially result in big confusion.


It is thought that if an output module actually needs access to the while msg 
object, we will (then) introduce a way to serialize it (e.g. to XML) in the 
property replacer. Then, the output module can work with this serialized object. 
The key point is that output modules never deal directly with msg objects (and 
other internal structures). Besides security, this also greatly simplifies the 
job of the output module developer.


Action Selectors


Modules (and rsyslog) need to know when they are called. For this, there must 
a an action identification in selector lines. There are two syntaxes: the 
single-character syntax, where a single characters identifies a module (e.g. "*" 
for a wall message) and the modules designator syntax, where the module name is 
given between colons (e.g. ":ommysql:"). The single character syntax is 
depreciated and should not be used for new plugins.


An in-depth discussion of module designation in action selectors can be found 
in this forum thread:

rsyslog.conf file


back


$ControlCharacterEscapePrefix


Type: global configuration directive


Default: \


Description:


This option specifies the prefix character to be used for control character escaping (see option $EscapeControlCharactersOnReceive). By default, it is '\', which is backwards-compatible with sysklogd. Change it to '#' in order to be compliant to the value that is somewhat suggested by Internet-Draft syslog-protocol.


IMPORTANT: do not use the ' character. This is reserved and will most probably be used in the future as a character delimiter. For the same reason, the syntax of this directive will probably change in future releases.


Sample:


$EscapeControlCharactersOnReceive #  # as of syslog-protocol

TLS-protected syslog: client setup




Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-07-03)





Setting up a client


In this step, we configure a client machine. We from our scenario, we use
zuse.example.net. You need to do the same steps for all other clients, too (in the
example, that meanst turng.example.net). The client check's the server's identity and
talks to it only if it is the expected server. This is a very important step.
Without it, you would not detect man-in-the-middle attacks or simple malicious servers
who try to get hold of your valuable log data.







Steps to do:

    

  • make sure you have a functional CA (Setting up the CA)

  • generate a machine certificate for zuse.example.net (follow instructions in
    Generating Machine Certificates)

  • make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the client.
Ensure that no user except root can access them (even read permissions are really bad).

  • configure the client so that it checks the server identity and sends messages only
if the server identity is known. Please note that you have the same options as when
configuring a server. However, we now use a single name only, because there is only one
central server. No using wildcards make sure that we will exclusively talk to that server
(otherwise, a compromised client may take over its role). If you load-balance to different
server identies, you obviously need to allow all of them. It still is suggested to use
explcit names.



At this point, please be reminded once again that your security needs may be quite different from
what we assume in this tutorial. Evaluate your options based on your security needs.

Sample syslog.conf


Keep in mind that this rsyslog.conf sends messages via TCP, only. Also, we do not
show any rules to write local files. Feel free to add them.

# make gtls driver the default
$DefaultNetstreamDriver gtls

# certificate files
$DefaultNetstreamDriverCAFile /rsyslog/protected/ca.pem
$DefaultNetstreamDriverCertFile /rsyslog/protected/machine-cert.pem
$DefaultNetstreamDriverKeyFile /rsyslog/protected/machine-key.pem

$ActionSendStreamDriverAuthMode x509/name
$ActionSendStreamDriverPermittedPeer central.example.net
$ActionSendStreamDriverMode 1 # run driver in TLS-only mode
*.* @@central.example.net:10514 # forward everything to remote server



Note: the example above forwards every message to the remote server. Of course,
you can use the normal filters to restrict the set of information that is sent.
Depending on your message volume and needs, this may be a smart thing to do.

Be sure to safeguard at least the private key (machine-key.pem)!
If some third party obtains it, you security is broken!

stdout output module (omstdout)


rsyslog module reference


stdout output module (stdout)


Module Name:    omstdout


Author: Rainer Gerhards
<rgerhards@adiscon.com>


Available Since: 4.1.6


Description:


This module writes any messages that are passed to it to stdout.
It was developed for the rsyslog test suite. However, there may
(limited) other uses exists. Please not that we do not put too much
effort into the quality of this module as we do not expect it to
be used in real deployments. If you do, please drop us a note so
that we can enhance its priority!

Configuration Directives:


    

  • $ActionOMStdoutArrayInterface [on|off
    
This setting instructs omstdout to use the alternate
array based method of parameter passing. If used, the values
will be output with commas between the values but no other padding bytes.
This is a test aid for the alternate calling interface.

  • $ActionOMStdoutEnsureLFEnding [on|off
    
Makes sure that each message is written with a terminating LF. This is needed for
the automatted tests. If the message contains a trailing LF, none is added.


Caveats/Known Bugs:

Currently none known.

Multiple Rulesets in rsyslog


Multiple Rulesets in rsyslog


Starting with version 4.5.0 and 5.1.1, rsyslog supports
multiple rulesets within a single configuration.
This is especially useful for routing the recpetion of remote messages to a set of specific rules.
Note that the input module must support binding to non-standard rulesets, so the functionality
may not be available with all inputs.

In this document, I am using imtcp, an input module
that supports binding to non-standard rulesets since rsyslog started to support them.

What is a Ruleset?

If you have worked with (r)syslog.conf, you know that it is made up of what I call rules (others
tend to call them selectors, a sysklogd term). Each rule consist of a filter and one or more
actions to be carried out when the filter evaluates to true. A filter may be as simple as a
traditional
syslog priority based filter (like "*.*" or "mail.info" or a as complex as a
script-like expression. Details on that are covered in the config file documentation. After the
filter come action specifiers, and an action is something that does something to a message, e.g.
write it to a file or forward it to a remote logging server.


A traditional configuration file is made up of one or more of these rules. When a new
message arrives, its processing starts with the first rule (in order of appearance in
rsyslog.conf) and continues for each rule until either all rules have been processed or
a so-called "discard" action happens, in which case processing stops and the
message is thrown away (what also happens after the last rule has been processed).


The multi-ruleset support now permits to specify more than one such rule sequence.
You can think of a traditional config file just as a single default rule set, which is
automatically bound to each of the inputs. This is even what actually happens. When
rsyslog.conf is processed, the config file parser looks for the directive


ruleset(name="rulesetname");




Where name is any name the user likes (but must not start with "RSYSLOG_", which
is the name space reserved for rsyslog use). If it finds this directive, it begins a new
rule set (if the name was not yet know) or switches to an already-existing one (if the name
was known). All rules defined between this $RuleSet directive and the next one are appended
to the named ruleset. Note that the reserved name "RSYSLOG_DefaultRuleset" is used to
specify rsyslogd's default ruleset. You can use that name whereever you can use a ruleset name,
including when binding an input to it.


Inside a ruleset, messages are processed as described above: they start with the first rule
and rules are processed in the order of appearance of the configuration file until either
there are no more rules or the discard action is executed. Note that with multiple rulesets
no longer all rsyslog.conf rules are executed but only those that are 
contained within the specific ruleset.


Inputs must explicitely bind to rulesets. If they don't do, the default ruleset is bound.


This brings up the next question:


What does "To bind to a Ruleset" mean?


This term is used in the same sense as "to bind an IP address to an interface":
it means that a specific input, or part of an input (like a tcp listener) will use a specific
ruleset to "pass its messages to". So when a new message arrives, it will be processed
via the bound ruleset. Rule from all other rulesets are irrelevant and will never be processed.

This makes multiple rulesets very handy to process local and remote message via
seperate means: bind the respective receivers to different rule sets, and you do not need
to seperate the messages by any other method.


Binding to rulesets is input-specifc. For imtcp, this is done via the 


input(type="imptcp" port="514" ruleset="rulesetname");



directive. Note that "name" must be the name of a ruleset that is already defined
at the time the bind directive is given. There are many ways to make sure this happens, but
I personally think that it is best to define all rule sets at the top of rsyslog.conf and
define the inputs at the bottom. This kind of reverses the traditional recommended ordering, but
seems to be a really useful and straightforward way of doing things.

Why are rulesets important for different parser configurations?


Custom message parsers, used to handle differnet (and potentially otherwise-invalid)
message formats, can be bound to rulesets. So multiple rulesets can be a very useful
way to handle devices sending messages in different malformed formats in a consistent
way. Unfortunately, this is not uncommon in the syslog world. An in-depth explanation
with configuration sample can be found at the
$RulesetParser configuration directive.

Can I use a different Ruleset as the default?


This is possible by using the


$DefaultRuleset <name>



Directive. Please note, however, that this directive is actually global: that is, it does not
modify the ruleset to which the next input is bound but rather provides a system-wide
default rule set for those inputs that did not explicitly bind to one. As such, the directive
can not be used as a work-around to bind inputs to non-default rulesets that do not support
ruleset binding.

Examples


Split local and remote logging


Let's say you have a pretty standard system that logs its local messages to the usual
bunch of files that are specified in the default rsyslog.conf. As an example, your rsyslog.conf
might look like this:


# ... module loading ...
# The authpriv file has restricted access.
authpriv.*  /var/log/secure
# Log all the mail messages in one place.
mail.*      /var/log/maillog
# Log cron stuff
cron.*      /var/log/cron
# Everybody gets emergency messages
*.emerg     *
... more ...




Now, you want to add receive messages from a remote system and log these to
a special file, but you do not want to have these messages written to the files
specified above. The traditional approach is to add a rule in front of all others that
filters on the message, processes it and then discards it:


# ... module loading ...
# process remote messages
if $fromhost-ip == '192.168.152.137' then {
        action(type="omfile" file="/var/log/remotefile02")
		stop
	}


# only messages not from 192.0.21 make it past this point

# The authpriv file has restricted access.
authpriv.*                            /var/log/secure
# Log all the mail messages in one place.
mail.*                                /var/log/maillog
# Log cron stuff
cron.*                                /var/log/cron
# Everybody gets emergency messages
*.emerg                               *
... more ...




Note that "stop" is the discard action!. Also note that we assume that
192.0.2.1 is the sole remote sender (to keep it simple).


With multiple rulesets, we can simply define a dedicated ruleset for the remote reception
case and bind it to the receiver. This may be written as follows:


# ... module loading ...
# process remote messages
# define new ruleset and add rules to it:
ruleset(name="remote"){
	action(type="omfile" file="/var/log/remotefile")
}
# only messages not from 192.0.21 make it past this point

# bind ruleset to tcp listener and activate it:
input(type="imptcp" port="10514" ruleset="remote")




Split local and remote logging for three different ports


This example is almost like the first one, but it extends it a little bit. While it is
very similar, I hope it is different enough to provide a useful example why you may want
to have more than two rulesets.


Again, we would like to use the "regular" log files for local logging, only. But
this time we set up three syslog/tcp listeners, each one listening to a different
port (in this example 10514, 10515, and 10516). Logs received from these receivers shall go into
different files. Also, logs received from 10516 (and only from that port!) with
"mail.*" priority, shall be written into a specif file and not be
written to 10516's general log file.


This is the config:


# ... module loading ...
# process remote messages

ruleset(name="remote10514"){
	action(type="omfile" file="/var/log/remote10514")
}

ruleset(name="remote10515"){
	action(type="omfile" file="/var/log/remote10515")
}

ruleset(name="test1"){
	if prifilt("mail.*") then {
		/var/log/mail10516
		stop
		# note that the stop-command will prevent this message from 
		# being written to the remote10516 file - as usual...	
	}
	/var/log/remote10516
}


# and now define listeners bound to the relevant ruleset
input(type="imptcp" port="10514" ruleset="remote10514")
input(type="imptcp" port="10515" ruleset="remote10515")
input(type="imptcp" port="10516" ruleset="remote10516")







Performance


Fewer Filters


No rule processing can be faster than not processing a rule at all. As such, it is useful
for a high performance system to identify disjunct actions and try to split these off to
different rule sets. In the example section, we had a case where three different tcp listeners
need to write to three different files. This is a perfect example of where multiple rule sets
are easier to use and offer more performance. The performance is better simply because there
is no need to check the reception service - instead messages are automatically pushed to the
right rule set and can be processed by very simple rules (maybe even with
"*.*"-filters, the fastest ones available).


Partitioning of Input Data


Starting with rsyslog 5.3.4, rulesets permit higher concurrency. They offer the ability
to run on their own "main" queue. What that means is that a own queue is associated
with a specific rule set. That means that inputs bound to that ruleset do no longer need
to compete with each other when they enqueue a data element into the queue. Instead, enqueue
operations can be completed in parallel.

An example: let us assume we have three TCP listeners. Without rulesets, each of them
needs to insert messages into the main message queue. So if each of them wants to
submit a newly arrived message into the queue at the same time, only one can do so
while the others need to wait. With multiple rulesets, its own queue can be created for each
ruleset. If now each listener is bound to its own ruleset, concurrent message submission is
possible. On a machine with a sufficiently large number of corse, this can result in
dramatic performance improvement.

It is highly advised that high-performance systems define a dedicated ruleset, with a
dedicated queue for each of the inputs.

By default, rulesets do not have their own queue. It must be activated via the
$RulesetCreateMainQueue directive.

rsyslog licensing




rsyslog licensing


Most important things first: if you intend to use rsyslog inside a GPLv3 compatible project, you are free to do so. You don't even need to continue reading. 
If you intend to use rsyslog inside a non-GPLv3 
compatible project, rsyslog offers you some liberties to do that, too. However, you then need
to study the licensing details in depth.

The project hopes this is a good compromise, which also gives a boost to fellow free 
software developers who release under GPLv3.

And now on to the dirty and boring license details, still on a executive summary level. For the
real details, check source files and the files COPYING and COPYING.LESSER inside the distribution.

The rsyslog package contains several components:

    

  • the rsyslog core programs (like rsyslogd)

  • plugins (like imklog, omrelp, ...)

  • the rsyslog runtime library



Each of these components can be thought of as individual projects. In fact, some of the
plugins have different main authors than the rest of the rsyslog package. All of these
components are currently put together into a single "rsyslog" package (tarball) for
convinience: this makes it easier to distribute a consistent version where everything
is included (and in the right versions) to build a full system. Platform package 
maintainers in general take the overall package and split off the individual components, so that
users can install only what they need. In source installations, this can be done via the
proper ./configure switches.

However, while it is convenient to package all parts in a single tarball, it does not
imply all of them are necessarily covered by the same license. Traditionally, GPL licenses
are used for rsyslog, because the project would like to provide free software. GPLv3 has been
used since around 2008 to help fight for our freedom. All rsyslog core programs are
released under GPLv3. But, from the beginning on, plugins were separate projects and we did not
impose and license restrictions on them. So even though all plugins that currently ship with
the rsyslog package are also placed under GPLv3, this can not taken for granted. You need
to check each plugins license terms if in question - this is especially important for
plugins that do NOT ship as part of the rsyslog tarball.

In order to make rsyslog technology available to a broader range of applications, 
the rsyslog runtime is, at least partly, licensed under LGPL. If in doubt, check the source file
licensing comments. As of now, the following files are licensed under LGPL:

    

  • queue.c/.h

  • wti.c/.h

  • wtp.c/.h

  • vm.c/.h

  • vmop.c/.h

  • vmprg.c/.h

  • vmstk.c/.h

  • expr.c/.h

  • sysvar.c/.h

  • ctok.c/.h

  • ctok_token.c/.h

  • regexp.c/.h

  • sync.c/.h

  • stream.c/.h

  • var.c/.h


This list will change as time of the runtime modularization. At some point in the future, there will
be a well-designed set of files inside a runtime library branch and all of these will be LGPL. Some
select extras will probably still be covered by GPL. We are following a similar licensing
model in GnuTLS, which makes effort to reserve some functionality exclusively to open source
projects.

GSSAPI Syslog Input Module



back


GSSAPI Syslog Input Module


Module Name:    imgssapi


Author: varmojfekoj


Description:


Provides the ability to receive syslog messages from the
network protected via Kerberos 5 encryption and authentication. This
module also accept plain tcp syslog messages on the same port if configured to do so. If you need just plain tcp, use imtcp instead.


There is also an overview of gssapi support in rsyslog available. We recommend reading
it before digging into the configuration parameters.


Configuration Directives:


    

  • InputGSSServerRun <port>
    
Starts a GSSAPI server on selected port - note that this runs
independently from the TCP server.
    • 

  • InputGSSServerServiceName <name>
    
The service name to use for the GSS server.
    • 

  • $InputGSSServerPermitPlainTCP on|off
    
Permits the server to receive plain tcp syslog (without GSS) on the
same port
    • 

  • $InputGSSServerMaxSessions <number>
    
Sets the maximum number of sessions supported
    • 


Caveats/Known Bugs:

    

  • module always binds to all interfaces
    • 

  • only a single listener can be bound
    • 




Sample:


This sets up a GSS server on port 1514 that also permits to
receive plain tcp syslog messages (on the same port):

dropping privileges in rsyslog



Dropping privileges in rsyslog


Available since:    4.1.1


Description:



Rsyslogd provides the ability to drop privileges by
impersonating as another user and/or group after startup.


Please note that due to POSIX standards, rsyslogd always needs to start
up as root if there is a listener who must bind to a network port below 1024.
For example, the UDP listener usually needs to listen to 514 and as such
rsyslogd needs to start up as root.


If you do not need this functionality, you can start rsyslog directly as an ordinary
user. That is probably the safest way of operations. However, if a startup as
root is required, you can use the $PrivDropToGroup and $PrivDropToUser config
directives to specify a group and/or user that rsyslogd should drop to after initialization.
Once this happend, the daemon runs without high privileges (depending, of
course, on the permissions of the user account you specified). 

There is some additional information available in the
rsyslog wiki.

Configuration Directives:


    

  • $PrivDropToUser
    
Name of the user rsyslog should run under after startup. Please note that
this user is looked up in the system tables. If the lookup fails, privileges are
NOT dropped. Thus it is advisable to use the less convenient $PrivDropToUserID directive.
If the user id can be looked up, but can not be set, rsyslog aborts.

    

    • 

  • $PrivDropToUserID
    
Much the same as $PrivDropToUser, except that a numerical user id instead of a name
is specified.Thus, privilege drop will always happen. 
rsyslogd aborts.

  • $PrivDropToGroup
    
Name of the group rsyslog should run under after startup. Please note that
this user is looked up in the system tables. If the lookup fails, privileges are
NOT dropped. Thus it is advisable to use the less convenient $PrivDropToGroupID directive.
Note that all supplementary groups are removed from the process if $PrivDropToGroup is
specified.
If the group id can be looked up, but can not be set, rsyslog aborts.

    

    • 

  • $PrivDropToGroupID

is specified. Thus, privilege drop will always happen.

$AllowedSender


Type: global configuration directive


Default: all allowed


Description:


Allowed sender lists can be used to specify which remote systems are allowed to send syslog messages to rsyslogd. With them, further hurdles can be placed between an attacker and rsyslogd. If a message from a system not in the allowed sender list is received, that message is discarded. A diagnostic message is logged, so that the fact is recorded (this message can be turned off with the "-w" rsyslogd command line option).


Allowed sender lists can be defined for UDP and TCP senders separately. There can be as many allowed senders as needed. The syntax to specify them is:


$AllowedSender , ip[/bits], ip[/bits]


"$AllowedSender" is the directive - it must be written exactly as shown and the $ must start at the first column of the line. "" is either "UDP" or "TCP". It must immediately be followed by the comma, else you will receive an error message. "ip[/bits]" is a machine or network ip address as in "192.0.2.0/24" or "127.0.0.1". If the "/bits" part is omitted, a single host is assumed (32 bits or mask 255.255.255.255). "/0" is not allowed, because that would match any sending system. If you intend to do that, just remove all $AllowedSender directives. If more than 32 bits are requested with IPv4, they are adjusted to 32. For IPv6, the limit is 128 for obvious reasons. Hostnames, with and without wildcards, may also be provided. If so, the result of revers DNS resolution is used for filtering. Multiple allowed senders can be specified in a comma-delimited list. Also, multiple $AllowedSender lines can be given. They are all combined into one UDP and one TCP list. Performance-wise, it is good to specify those allowed senders with high traffic volume before those with lower volume. As soon as a match is found, no further evaluation is necessary and so you can save CPU cycles.


Rsyslogd handles allowed sender detection very early in the code, nearly as the first action after receiving a message. This keeps the access to potential vulnerable code in rsyslog at a minimum. However, it is still a good idea to impose allowed sender limitations via firewalling.


WARNING: by UDP design, rsyslogd can not identify a spoofed sender address in UDP syslog packets. As such, a malicious person could spoof the address of an allowed sender, send such packets to rsyslogd and rsyslogd would accept them as being from the faked sender. To prevent this, use syslog via TCP exclusively. If you need to use UDP-based syslog, make sure that you do proper egress and ingress filtering at the firewall and router level.


Rsyslog also detects some kind of malicious reverse DNS entries. In any case, using DNS names adds an extra layer of vulnerability. We recommend to stick with hard-coded IP addresses wherever possible.


Sample:


$AllowedSender UDP, 127.0.0.1, 192.0.2.0/24, [::1]/128, *.example.net, somehost.example.com

TLS-protected syslog: central server setup




Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-06-18)





Setting up the Central Server


In this step, we configure the central server. We assume it accepts messages only
via TLS protected plain tcp based syslog from those peers that are explicitely permitted
to send to it. The picture below show our configuration. This step configures
the server central.example.net.







Important: Keep in mind that the order of configuration directives
is very important in rsyslog. As such, the samples given below do only work if the given
order is preserved. Re-ordering the directives can break configurations and has broken them
in practice. If you intend to re-order them, please be sure that you fully understand how
the configuration language works and, most importantly, which statements form a block together.
Please also note that we understand the the current configuration file format is
ugly. However, there has been more important work in the way of enhancing it. If you would like
to contribute some time to improve the config file language, please let us know. Any help
is appreciated (be it doc or coding work!).

Steps to do:

    

  • make sure you have a functional CA (Setting up the CA)

  • generate a machine certificate for central.example.net (follow instructions in
    Generating Machine Certificates)

  • make sure you copy over ca.pem, machine-key.pem ad machine-cert.pem to the central server.
Ensure that no user except root can access them (even read permissions are really bad).

  • configure the server so that it accepts messages from all machines in the
example.net domain that have certificates from your CA. Alternatively, you may also
precisely define from which machine names messages are accepted. See sample rsyslog.conf
below.


In this setup, we use wildcards to ease adding new systems. We permit the server to accept
messages from systems whos names match *.example.net.


$InputTCPServerStreamDriverPermittedPeer *.example.net


This will match zuse.example.net and
turing.example.net, but NOT pascal.otherdepartment.example.net. If the later would be desired,
you can (and need) to include additional permitted peer config statments:


$InputTCPServerStreamDriverPermittedPeer *.example.net
$InputTCPServerStreamDriverPermittedPeer *.otherdepartment.example.net
$InputTCPServerStreamDriverPermittedPeer *.example.com



As can be seen with example.com, the different permitted peers need NOT to be in a single
domain tree. Also, individual machines can be configured. For example, if only zuse, turing
and ada should be able to talk to the server, you can achive this by:


$InputTCPServerStreamDriverPermittedPeer zuse.example.net
$InputTCPServerStreamDriverPermittedPeer turing.example.net
$InputTCPServerStreamDriverPermittedPeer ada.example.net



As an extension to the (upcoming) IETF syslog/tls standard, you can specify some text
together with a domain component wildcard. So "*server.example.net", "server*.example.net"
are valid permitted peers. However "server*Fix.example.net" is NOT a valid wildcard. The
IETF standard permits no text along the wildcards.

The reason we use wildcards in the default setup is that it makes it easy to add systems
without the need to change the central server's configuration. It is important to understand that
the central server will accept names only (no exception) if the client certificate was
signed by the CA we set up. So if someone tries to create a malicious certificate with
a name "zuse.example.net", the server will not accept it. So a wildcard is safe
as long as you ensure CA security is not breached. Actually, you authorize a client by issuing
the certificate to it.

At this point, please be reminded once again that your security needs may be quite different from
what we assume in this tutorial. Evaluate your options based on your security needs.

Sample syslog.conf


Keep in mind that this rsyslog.conf accepts messages via TCP, only. The only other
source accepted is messages from the server itself.

$ModLoad imuxsock # local messages
$ModLoad imtcp # TCP listener

# make gtls driver the default
$DefaultNetstreamDriver gtls

# certificate files
$DefaultNetstreamDriverCAFile /rsyslog/protected/ca.pem
$DefaultNetstreamDriverCertFile /rsyslog/protected/machine-cert.pem
$DefaultNetstreamDriverKeyFile /rsyslog/protected/machine-key.pem

$InputTCPServerStreamDriverAuthMode x509/name
$InputTCPServerStreamDriverPermittedPeer *.example.net
$InputTCPServerStreamDriverMode 1 # run driver in TLS-only mode
$InputTCPServerRun 10514 # start up listener at port 10514



Be sure to safeguard at least the private key (machine-key.pem)!
If some third party obtains it, you security is broken!

rsyslog.conf file


back


$IncludeConfig


Type: global configuration directive


Default: 


Description:


This directive allows to include other files into the main configuration file. As soon as an IncludeConfig directive is found, the contents of the new file is processed. IncludeConfigs can be nested. Please note that from a logical point of view the files are merged. Thus, if the include modifies some parameters (e.g. $DynaFileChacheSize), these new parameters are in place for the "calling" configuration file when the include is completed. To avoid any side effects, do a $ResetConfigVariables after the $IncludeConfig. It may also be a good idea to do a $ResetConfigVariables right at the start of the include, so that the module knows exactly what it does. Of course, one might specifically NOT do this to inherit parameters from the main file. As always, use it as it best fits...


If all regular files in the /etc/rsyslog.d directory are included, then files starting with "." are ignored - so you can use them to place comments into the dir (e.g. "/etc/rsyslog.d/.mycomment" will be ignored). Michael Biebl had the idea to this functionality. Let me quote hm:




Say you can add an option

$IncludeConfig /etc/rsyslog.d/

(which probably would make a good default)

to /etc/rsyslog.conf, which would then merge and include all *.conf files

in /etc/rsyslog.d/.



This way, a distribution can modify its packages easily to drop a simple

config file into this directory upon installation.



As an example, the network-manager package could install a simple config

file /etc/rsyslog.d/network-manager.conf which would contain.

:programname, contains, "NetworkManager" -/var/log/NetworkManager.log



Upon uninstallation, the file could be easily removed again. This approach

would be much cleaner and less error prone, than having to munge around

with the /etc/rsyslog.conf file directly.




Sample:


$IncludeConfig /etc/some-included-file.conf


Directories can also be included. To do so, the name must end on a slash:


$IncludeConfig /etc/rsyslog.d/


And finally, only specific files matching a wildcard my be included 
from a directory:


$IncludeConfig /etc/rsyslog.d/*.conf

TLS (SSL) Encrypting syslog

Encrypting Syslog Traffic with TLS (SSL)


Written by Rainer
Gerhards (2008-05-06)


Abstract


In this paper, I describe how to encrypt syslog
messages on the network. Encryption
is vital to keep the confidiental content of syslog messages secure. I
describe the overall
approach and provide an HOWTO do it with rsyslog's TLS
features. 


Please
note that TLS is the more secure successor of SSL. While people often
talk about "SSL encryption" they actually mean "TLS encryption". So
don't look any further if you look for how to SSL-encrypt syslog. You
have found the right spot.


This is a quick guide. There is a more elaborate guide currently
under construction which provides a much more secure environment. It
is highly recommended to
at least have a look at it.

Background


Traditional syslog is a clear-text protocol. That
means anyone with a sniffer can have a peek at your data. In
some environments, this is no problem at all. In others, it is a huge
setback, probably even preventing deployment of syslog solutions.
Thankfully, there are easy ways to encrypt syslog
communication. 

The traditional approach involves running
a wrapper like stunnel around the syslog session. This works
quite well and is in widespread use. However, it is not thightly
coupled with the main syslogd and some, even severe, problems can
result from this (follow a mailing list thread that describes total
loss of syslog messages due to stunnel mode and the unreliability
of TCP syslog).

Rsyslog supports syslog via
GSSAPI since long to overcome these limitatinos. However,
syslog via GSSAPI is a rsyslog-exclusive transfer mode and it requires
a proper Kerberos environment. As such, it isn't a really universal
solution. The IETF
has begun standardizing syslog over plain tcp over
TLS for a while now. While I am not fully satisfied with the results so
far, this obviously has the  potential to become the long-term
solution. The Internet Draft in question, syslog-transport-tls has been
dormant for some time but is now (May of 2008) again being worked on. I
expect it to turn into a RFC within the next 12 month (but don't take
this for granted ;)). I didn't want to wait for it, because there
obviously is need for TLS syslog right now (and, honestly, I have
waited long enough...). Consequently, I have
implemented the current draft, with some interpretations I made (there
will be a compliance doc soon). So in essence, a TLS-protected syslog
transfer mode is available right now. As a side-note, Rsyslog
is the world's first
implementation of syslog-transport-tls.


Please note that in theory it should be compatible with other,
non IETF syslog-transport-tls implementations. If you would like to run
it with something else, please let us know so that we can create a
compatibility list (and implement compatbility where it doesn't yet
exist). 


Overall System Setup


Encryption requires a reliable stream. So It will not work
over UDP syslog. In rsyslog, network transports utilize a so-called
"network stream layer" (netstream for short). This layer provides a
unified view of the transport to the application layer. The plain TCP
syslog sender and receiver are the upper layer. The driver layer
currently consists of the "ptcp" and "gtls" library plugins. "ptcp"
stands for "plain tcp" and is used for unencrypted message transfer. It
is also used internally by the gtls driver, so it must always be
present on a system. The "gtls" driver is for GnutTLS, a TLS library.
It is used for encrypted message transfer. In the future, additional
drivers will become available (most importantly, we would like to
include a driver for NSS).


What you need to do to build an encrypted syslog channel is to
simply use the proper netstream drivers on both the client and the
server. Client, in the sense of this document, is the rsyslog system
that is sending syslog messages to a remote (central) loghost, which is
called the server. In short, the setup is as follows:


Client


    

  • forwards messages via plain tcp syslog using gtls netstream
driver to central sever on port 10514
    

    • 



Server


    

  • accept incoming messages via plain tcp syslog using gtls
netstream driver on port 10514
    • 



Setting up the system


Server Setup


At the server, you need to have a digital certificate. That
certificate enables SSL operation, as it provides the necessary crypto
keys being used to secure the connection. There is a set of default
certificates in ./contrib/gnutls. These are key.pem and cert.pem. These
are good for testing. If you use it in production,
it is very easy to break into your secure channel as everybody is able
to get hold of your private key. So it is a good idea to
generate the key and certificate yourself.


You also need a root CA certificate. Again, there is a sample
CA certificate in ./contrib/gnutls, named ca.cert. It is suggested to
generate your own.


To configure the server, you need to tell it where are its
certificate files, to use the gtls driver and start up a listener. This
is done as follows:






# make gtls driver the default
$DefaultNetstreamDriver gtls

# certificate files
$DefaultNetstreamDriverCAFile /path/to/contrib/gnutls/ca.pem
$DefaultNetstreamDriverCertFile /path/to/contrib/gnutls/cert.pem
$DefaultNetstreamDriverKeyFile /path/to/contrib/gnutls/key.pem

$ModLoad imtcp # load TCP listener

$InputTCPServerStreamDriverMode 1 # run driver in TLS-only mode
$InputTCPServerStreamDriverAuthMode anon # client is NOT authenticated
$InputTCPServerRun 10514 # start up listener at port 10514




This is all you need to do. You can use the rest of your rsyslog.conf
together with this configuration. The way messages are received does
not interfer with any other option, so you are able to do anything else
you like without any restrictions.

Restart rsyslogd. The server should now be fully
operational.


Client Setup


The client setup is equally simple. You need less
certificates, just the CA cert. 




# certificate files - just CA for a client
$DefaultNetstreamDriverCAFile /path/to/contrib/gnutls/ca.pem

# set up the action
$DefaultNetstreamDriver gtls # use gtls netstream driver
$ActionSendStreamDriverMode 1 # require TLS for the connection
$ActionSendStreamDriverAuthMode anon # server is NOT authenticated
*.* @@(o)server.example.net:10514 # send (all) messages






Note that we use the regular TCP forwarding syntax (@@) here.
There is nothing special, because the encryption is handled by the
netstream driver. So I have just forwarded every message (*.*) for
simplicity - you can use any of rsyslog's filtering capabilities (like
epxression-based filters or regular expressions). Note that the "(o)"
part is not strictly necessary. It selects octet-based framing, which
provides compatiblity to IETF's syslog-transport-tls draft. Besides
compatibility, this is also a more reliable transfer mode, so I suggest
to always use it.


Done


After
following these steps, you should have a working secure
syslog forwarding system. To verify, you can type "logger test" or a
similar "smart" command on the client. It should show up in the
respective server log file. If you dig out your sniffer, you should see
that the traffic on the wire is actually protected.


Limitations


The
RELP transport can currently not be protected by TLS. A work-around is
to use stunnel. TLS support for RELP will be added once plain TCP
syslog has sufficiently matured and there either is some time left to do this
or we find a sponsor ;).


Certificates


In order to be really secure, certificates are needed. This is
a short summary on how to generate the necessary certificates with
GnuTLS' certtool. You can also generate certificates via other tools,
but as we currently support GnuTLS as the only TLS library, we thought
it is a good idea to use their tools.




Note that this section aims at people who are not involved
with PKI at all. The main goal is to get them going in a reasonable
secure way. 


CA Certificate


This is used to sign all of your other certificates. The CA
cert must be trusted by all clients and servers. The private key must
be well-protected and not given to any third parties. The certificate
itself can (and must) be distributed. To generate it, do the following:


    

  1. generate the private key:

    certtool --generate-privkey --outfile ca-key.pem
    

    
This takes a short while. Be sure to do some work on your workstation,
it waits for radom input. Switching between windows is sufficient ;)

    2. 

  2. now create the (self-signed) CA certificate itself:
    

    certtool --generate-self-signed --load-privkey ca-key.pem --outfile ca.pem
    
This generates the CA certificate. This command queries you for a
number of things. Use appropriate responses. When it comes to
certificate validity, keep in mind that you need to recreate all
certificates when this one expires. So it may be a good idea to use a
long period, eg. 3650 days (roughly 10 years). You need to specify that
the certificates belongs to an authrity. The certificate is used to
sign other certificates.
    

    3. 

  3. You need to distribute this certificate
to all peers and you need to point to it via the
$DefaultNetstreamDriverCAFile config directive. All other certificates
will be issued by this CA.
    
Important: do only distribute the ca.pem, NOT ca-key.pem (the private
key). Distributing the CA private key would totally breach security as
everybody could issue new certificates on the behalf of this CA.

    4. 



Individual Peer Certificate


Each peer (be it client, server or both), needs a certificate
that conveys its identity. Access control is based on these
certificates. You can, for example, configure a server to accept
connections only from configured clients. The client ID is taken from
the client instances certificate. So as a general rule of thumb, you
need to create a certificate for each instance of rsyslogd that you
run. That instance also needs the private key, so that it can properly
decrypt the traffic. Safeguard the peer's private key file. If somebody
gets hold of it, it can malicously pretend to be the compromised host.
If such happens, regenerate the certificate and make sure you use a
different name instead of the compromised one (if you use name-based
authentication). 


These are the steps to generate the indivudual certificates
(repeat: you need to do this for every instance, do NOT share the
certificates created in this step):


    

  1. generate a private key (do NOT mistake this with the CA's
private key - this one is different):
    

    certtool --generate-privkey --outfile key.pem
    
Again, this takes a short while.
    2. 

  2. generate a certificate request:
    

    certtool --generate-request --load-privkey key.pem --outfile request.pem
    
If you do not have the CA's private key (because you are not authorized
for this), you can send the certificate request to the responsible
person. If you do this, you can skip the remaining steps, as the CA
will provide you with the final certificate. If you submit the request
to the CA, you need to tell the CA the answers that you would normally
provide in step 3 below.

    3. 

  3. Sign (validate, authorize) the certificate request and
generate the instances certificate. You need to have the CA's
certificate and private key for this:
    

    certtool --generate-certificate --load-request request.pem --outfile cert.pem \
     --load-ca-certificate ca.pem --load-ca-privkey ca-key.pem
    
Answer questions as follows: Cert does not belogn to an authority; it
is a TLS web server and client certificate; the dnsName MUST be the
name of the peer in question (e.g. centralserver.example.net) - this is
the name used for authenticating the peers. Please note that you may
use an IP address in dnsName. This is a good idea if you would like to
use default server authentication and you use selector lines with IP
addresses (e.g. "*.* @@192.168.0.1") - in that case you need to select
a dnsName of 192.168.0.1. But, of course, changing the server IP then
requires generating a new certificate.
    4. 


After you have generated the certificate, you need to place it onto the
local machine running rsyslogd. Specify the certificate and key via the
$DefaultNetstreamDriverCertFile /path/to/cert.pem and
$DefaultNetstreamDriverKeyFile /path/to/key.pem configuration
directives. Make sure that nobody has access to key.pem, as that would
breach security. And, once again: do NOT use these files on more than
one instance. Doing so would prevent you from distinguising between the
instances and thus would disable useful authentication.

Troubleshooting Certificates


If you experience trouble with your certificate setup, it may
be
useful to get some information on what is contained in a specific
certificate (file). To obtain that information, do 


$ certtool --certificate-info --infile cert.pem


where "cert.pem" can be replaced by the various certificate pem files (but it does not work with the key files).


Conclusion


With minumal effort, you can set up a secure logging
infrastructure employing TLS encrypted syslog message transmission.

RSyslog - Features


This page lists both current features as well as
those being considered for future versions of rsyslog. If you
think a feature is missing, drop
Rainer a
note. Rsyslog is a vital project. Features are added each few days. If
you would like to keep up of what is going on, you can also subscribe
to the rsyslog
mailing list.


A better
structured feature list is now contained in our rsyslog
vs. syslog-ng comparison.
Probably that page will replace this one in the
future.



Current Features


    

  • native support for writing
to MySQL databases
    • 

  •  native support for writing to Postgres databases
    • 

  • direct support for Firebird/Interbase,
OpenTDS (MS SQL, Sybase), SQLLite, Ingres, Oracle, and mSQL via libdbi,
a database abstraction layer (almost as good as native)
    • 

  • native support for sending
mail messages (first seen in 3.17.0)
    • 

  • support for (plain) tcp based syslog - much better
reliability
    • 

  • support for sending and receiving compressed syslog messages
    • 

  • support for on-demand on-disk spooling of messages that can
not be processed fast enough (a great feature for writing massive
amounts of syslog messages to a database)
    • 

  • support for selectively processing
messages only during specific timeframes and spooling them to
disk otherwise
    • 

  • ability to monitor text files and convert their contents
into syslog messages (one per line)
    • 

  • ability to configure backup syslog/database servers - if
the primary fails, control is switched to a prioritized list of backups
    • 

  • support for receiving messages via reliable 
RFC 3195 delivery (a bit clumpsy to build right now...)
    • 

  • ability to generate file names and directories (log
targets) dynamically, based on many different properties
    • 

  • control of log output format, including ability to present
channel and priority as visible log data
    • 

  • good timestamp format control; at a minimum, ISO 8601/RFC
3339 second-resolution UTC zone
    • 

  • ability to reformat message contents and work with
substrings
    • 

  • support for log files larger than 2gb
    • 

  • support for file size limitation and automatic rollover
command execution
    • 

  • support for running multiple rsyslogd instances on a single
machine
    • 

  • support for TLS-protected
syslog (both natively
and via stunnel)
    • 

  • ability to filter on any part of the message, not just
facility and severity
    • 

  • ability to use regular expressions in filters
    • 

  • support for discarding messages based on filters
    • 

  • ability to execute shell scripts on received messages
    • 

  • control of whether the local hostname or the hostname of
the origin of the data is shown as the hostname in the output
    • 

  • ability to preserve the original hostname in NAT
environments and relay chains 
    • 

  • ability to limit the allowed network senders
    • 

  • powerful BSD-style hostname and program name blocks for
easy multi-host support
    • 

  •  massively multi-threaded with dynamic work thread pools
that start up and shut themselves down on an as-needed basis (great for
high log volume on multicore machines)
    • 

  • very experimental and volatile support for syslog-protocol
compliant messages (it is volatile because standardization is currently
underway and this is a proof-of-concept implementation to aid this
effort)
    • 

  •  world's first implementation of syslog-transport-tls
    • 

  •  the sysklogd's klogd functionality is implemented as the imklog
input plug-in. So rsyslog is a full replacement for the sysklogd package
    • 

  •  support for IPv6
    • 

  •  ability to control repeated line reduction ("last message
repeated n times") on a per selector-line basis
    • 

  •  supports sub-configuration files, which can be
automatically read from directories. Includes are specified in the main
configuration file
    • 

  •  supports multiple actions per selector/filter condition
    • 

  •  MySQL and Postgres SQL functionality as a dynamically
loadable plug-in
    • 

  •  modular design for inputs and outputs - easily extensible
via custom plugins
    • 

  •  an easy-to-write to plugin interface
    • 

  •  ability to send SNMP trap messages
    • 

  •  ability to filter out messages based on sequence of arrival
    • 

  • support for comma-seperated-values (CSV) output generation
(via the "csv" property replace option). The
CSV format supported is that from RFC 4180.
    • 

  • support for arbitrary complex boolean, string and
arithmetic expressions in message filters
    • 



World's first

Rsyslog has an interesting number of "world's firsts" - things that
were implemented for the first time ever in rsyslog. Some of them are still features not available elsewhere.
    

  • world's first implementation of IETF I-D syslog-protocol (February 2006, version 1.12.2 and above), now RFC5424
  • world's first implementation of dynamic syslog on-the-wire compression (December 2006, version 1.13.0 and above)
  • world's first open-source implementation of a disk-queueing syslogd (January 2008, version 3.11.0 and above)
    • 

  • world's first implementation of IETF I-D
syslog-transport-tls (May 2008, version 3.19.0 and above)
    • 



Upcoming Features


The list below is something like a repository of ideas we'd
like to implement. Features on this list are typically NOT scheduled
for immediate inclusion. We maintain a
feature
request tracker at our bugzilla. This tracker has things
typically within reach of implementation. Users are encouraged to
submit feature requests there (or via our forums). If we like them but
they look quite long-lived (aka "not soon to be implemented"), they
will possibly be migrated to this list here and at some time moved back
to the bugzilla tracker.


Note that we also maintain a
list of features that are looking for sponsors.
If you are interested in any of these features, or any other feature, you may consider sponsoring
the implementation. This is also a great way to show your commitment to the open source
community. Plus, it can be financially attractive: just think about how much less it may
be to sponsor a feature instead of purchasing a commercial implementation. Also, the benefit
of being recognised as a sponsor may even drive new customers to your business!

    

  • port it to more *nix variants (eg AIX and HP UX) - this
needs volunteers with access to those machines and knowledge 
    • 

  • pcre filtering - maybe (depending on feedback)  -
simple regex already partly added. So far, this seems sufficient so
that there is no urgent need to do pcre. If done, it will be a loadable RainerScript function.
    • 

  • support for RFC
3195 as a sender - this is currently unlikely to happen,
because there is no real demand for it. Any work on RFC 3195 has been
suspend until we see some real interest in it.  It is probably
much better to use TCP-based syslog, which is interoperable with a
large number of applications. You may also read my blog post on the
future of liblogging, which contains interesting information about the 
future of RFC 3195 in rsyslog.

rsyslog
change log (online only).

Linux Journal Output Module (omjournal)


back


Linux Journal Output Module (omjournal)


Module Name:    omjournal


Author: Rainer Gerhards <rgerhards@adiscon.com>


Available since: 7.3.7


Description:


The omjournal output module provides an interface to the Linux journal.
It is meant to be used in those cases where the Linux journal is being used
as the sole system log database. With omjournal, messages from various
sources (e.g. files and remote devices) can also be written to the journal
and processed by its tools.

A typical use case we had on our mind is a SOHO environment, where the
user wants to include syslog data obtained from the local router to be
part of the journal data.

We suggest to check out our short presentation on
rsyslog journal integration to
learn more details of anticipated use cases.

 



Module Configuration Parameters:


Currently none.

 


Action Confguration Parameters:


Currently none.


Caveats/Known Bugs:

    

  • One needs to be careful that no message routing loop is created. The 
systemd journal forwards messages it receives to the traditional syslog
system (if present). That means rsyslog will receive the same message that
it just wrote as new input on imuxsock. If not handled specially and assuming
all messages be written to the journal, the message would be emitted to the
journal again and a deadly loop is started.

    To prevent that, imuxsock by default does not accept messages originating
from its own process ID, aka it ignores messages from the current instance of
rsyslogd. However, this setting can be changed, and if so the problem may occur.




Sample:


We assume we have a DSL router inside the network and would like to
receive its syslog message into the journal. Note that this configuration can be
used without havoing any other syslog functionality at all (most importantly, there
is no need to write any file to /var/log!). We assume syslog over UDP, as this
is the most probable choice for the SOHO environment that this use case reflects.
To log to syslog data to the journal, add the following snippet to rsyslog.conf:


Note that this can be your sole rsyslog.conf if you do not use rsyslog
for anything else than receving the router syslog messages.

If you do not receive messages, you probably need to enable inbound UDP
syslog traffic in your firewall.

RainerScript ABNF


RainerScript ABNF


This is the formal definition of RainerScript, as supported by
rsyslog configuration. Please note that this currently is working
document and the actual implementation may be quite different.


The
first glimpse of RainerScript will be available as part of rsyslog
3.12.0 expression support. However, the 3.12. series of rsyslog will
have a partial script implementaiton, which will not necessariy be
compatible with the later full implementation. So if you use it, be
prepared for some config file changes as RainerScript evolves.


C-like comments (/* some comment */) are supported in all pure
RainerScript lines. However, legacy-mapped lines do not support them.
All lines support the hash mark "#" as a comment initiator. Everything
between the hash and the end of line is a comment (just like // in C++
and many other languages).


Formal Definition


Below is the formal language definitionin ABNF (RFC 2234)
format:

ceevar := "!" name

sysvar := "$" name

    [?action.template='templatename'?] or [?action.sql='insert into table... values(' & $facility & ','  & $severity &...?]
   endaction
if $message contains "error" then action writeMySQL

    action.dbname='events', action.dbuser='uid',
 
  [?action.template='templatename'?] or [?action.sql='insert into

Implementation

RainerScript will be implemented via a hand-crafted LL(1) parser. I was tempted to use yacc, but it turned out the resulting code was not thread-safe and as such did not fit within the context of rsyslog. Also, limited error handling is not a real problem for us: if there is a problem in parsing the configuration file, we stop processing. Guessing what was meant and trying to recover would IMHO not be good choices for something like a syslogd.

Writing syslog Data to MySQL

Writing syslog messages to MySQL


Written by Rainer
Gerhards (2008-02-28)


Abstract


In this paper, I describe how to write
syslog
messages to a MySQL
database. Having syslog messages in a database is often
handy, especially when you intend to set up a front-end for viewing
them. This paper describes an approach with rsyslogd,
an
alternative enhanced syslog daemon natively supporting MySQL. I
describe the components needed to be installed and how to configure
them. Please note that as of this writing, rsyslog supports a variety
of databases. While this guide is still MySQL-focussed, you
can probably use it together with other ones too. You just need to
modify a few settings.


Background


In many cases, syslog data is simply written to text files.
This approach has some advantages, most notably it is very fast and
efficient. However, data stored in text files is not readily accessible
for real-time viewing and analysis. To do that, the messages need to be
in a database. There are various ways to store syslog messages in a
database. For example, some have the syslogd write text files which are
later feed via a separate script into the database. Others have written
scripts taking the data (via a pipe) from a non-database-aware syslogd
and store them as they appear. Some others use database-aware syslogds
and make them write the data directly to the database. In this paper, I
use that "direct write" approach. I think it is superior, because the
syslogd itself knows the status of the database connection and thus can
handle it intelligently (well ... hopefully ;)). I use rsyslogd to
acomplish this, simply because I have initiated the rsyslog project
with database-awareness as one goal.


One word of caution: while message storage
in the database provides an excellent foundation for interactive
analysis, it comes at a cost. Database i/o is considerably slower than
text file i/o. As such, directly writing to the database makes sense
only if your message volume is low enough to allow a) the syslogd, b)
the network, and c) the database server to catch up with it. Some time
ago, I have written a paper on
optimizing
syslog server performance. While this paper talks about
Window-based solutions, the ideas in it are generic enough to apply
here, too. So it might be worth reading if you anticipate medium high
to high traffic. If you anticipate really high traffic (or very large
traffic spikes), you should seriously consider forgetting about direct
database writes - in my opinion, such a situation needs either a very
specialised system or a different approach (the text-file-to-database
approach might work better for you in this case).



Overall System Setup


In this paper, I concentrate on the server side. If you are
thinking about interactive syslog message review, you probably want to
centralize syslog. In such a scenario, you have multiple machines (the
so-called clients) send their data to a central machine (called server
in this context). While I expect such a setup to be typical when you
are interested in storing messages in the database, I do not describe
how to set it up. This is beyond the scope of this paper. If you search
a little, you will probably find many good descriptions on how to
centralize syslog. If you do that, it might be a good idea to do it
securely, so you might also be interested in my paper on 
ssl-encrypting syslog message transfer.


No matter how the messages arrive at the server, their
processing is always the same. So you can use this paper in combination
with any description for centralized syslog reporting.


As I already said, I use rsyslogd on the server. It has
intrinsic support for talking to MySQL databases. For obvious reasons,
we also need an instance of MySQL running. To keep us focussed, the
setup of MySQL itself is also beyond the scope of this paper. I assume
that you have successfully installed MySQL and also have a front-end at
hand to work with it (for example,
phpMyAdmin).
Please make sure that this is installed, actually working and you have
a basic understanding of how to handle it.


Setting up the system


You need to download and install rsyslogd first. Obtain it
from the
rsyslog site.
Make sure that you disable stock syslogd, otherwise you will experience
some difficulties. On some distributions  (Fedora 8 and above, for
example), rsyslog may already by the default syslogd, in which case you
obviously do not need to do anything specific. For many others, there
are prebuild packages available. If you use either, please make sure
that you have the required database plugins for your database
available. It usually is a separate package and typically not installed by default.


It is important to understand how rsyslogd talks to the
database. In rsyslogd, there is the concept of "templates". Basically,
a template is a string that includes some replacement characters, which
are called "properties" in rsyslog. Properties are accessed via the "Property Replacer".
Simply said, you access properties by including their name between
percent signs inside the template. For example, if the syslog message
is "Test", the template "%msg%" would be expanded to "Test". Rsyslogd
supports sending template text as a SQL statement to MySQL. As such,
the template must be a valid SQL statement. There is no limit in what
the statement might be, but there are some obvious and not so obvious
choices. For example, a template "drop table xxx" is possible, but does
not make an awful lot of sense. In practice, you will always use an
"insert" statment inside the template.


An example: if you would just like to store the msg part of
the full syslog message, you have probably created a table "syslog"
with a single column "message". In such a case, a good template would
be "insert into syslog(message) values ('%msg%')". With the example
above, that would be expanded to "insert into syslog(message)
values('Test')". This expanded string is then sent to the database.
It's that easy, no special magic. The only thing you must ensure is
that your template expands to a proper SQL statement and that this
statement matches your database design.


Does that mean you need to create database schema yourself and
also must fully understand rsyslogd's properties? No, that's not
needed. Because we anticipated that folks are probably more interested
in getting things going instead of designing them from scratch. So we
have provided a default schema as well as build-in support for it. This
schema also offers an additional benefit: rsyslog is part of Adiscon's
MonitorWare
product line (which includes open source and closed source
members). All of these tools share the same default schema and know how
to operate on it. For this reason, the default schema is also called
the "MonitorWare Schema". If you use it, you can simply add phpLogCon, a GPLed syslog
web interface, to your system and have instant interactive
access to your database. So there are some benefits in using the
provided schema.


The schema definition is contained in the file "createDB.sql".
It comes with the rsyslog package. Review it to check that the database
name is acceptable for you. Be sure to leave the table and field names
unmodified, because otherwise you need to customize rsyslogd's default
sql template, which we do not do in this paper. Then, run the script
with your favourite MySQL tool. Double-check that the table was
successfully created.


MySQL support in rsyslog is integrated via a loadable plug-in
module. To use the database
functionality, MySQL must be enabled in the config file BEFORE the
first database table action is
used. This is done by placing the




$ModLoad ommysql




directive at the begining of /etc/rsyslog.conf. For other databases, use their plugin name (e.g. ompgsql).


Next, we need to tell rsyslogd to write data to the database.
As we use the default schema, we do NOT need to define a template for
this. We can use the hardcoded one (rsyslogd handles the proper
template linking). So all we need to do is add a simple selector line
to /etc/rsyslog.conf:




*.*       :ommysql:database-server,database-name,database-userid,database-password




Again, other databases have other selector names, e.g. ":ompgsql:"
instead of ":ommysql:". See the output plugin's documentation for
details.
In many cases, MySQL will run on the local machine. In this
case, you can simply use "127.0.0.1" for database-server.
This can be especially advisable, if you do not need to expose MySQL to
any process outside of the local machine. In this case, you can simply
bind it to 127.0.0.1, which provides a quite secure setup. Of course,
also supports remote MySQL instances. In that case, use the remote
server name (e.g. mysql.example.com) or IP-address. The 
database-name by default is "syslog". If you have modified
the default, use your name here. Database-userid
and -password are the credentials used to connect
to the database. As they are stored in clear text in rsyslog.conf, that
user should have only the least possible privileges. It is sufficient
to grant it INSERT privileges to the systemevents table, only. As a
side note, it is strongly advisable to make the rsyslog.conf file
readable by root only - if you make it world-readable, everybody could
obtain the password (and eventually other vital information from it).
In our example, let's assume you have created a MySQL user named
"syslogwriter" with a password of "topsecret" (just to say it bluntly:
such a password is NOT a good idea...). If your MySQL database is on
the local machine, your rsyslog.conf line might look like in this
sample:




*.*       :ommysql:127.0.0.1,Syslog,syslogwriter,topsecret




Save rsyslog.conf, restart rsyslogd - and you should see
syslog messages being stored in the "systemevents" table!


The example line stores every message to the database.
Especially if you have a high traffic volume, you will probably limit
the amount of messages being logged. This is easy to acomplish: the
"write database" action is just a regular selector line. As such, you
can apply normal selector-line filtering. If, for example, you are only
interested in messages from the mail subsystem, you can use the
following selector line:




mail.*       :ommysql:127.0.0.1,syslog,syslogwriter,topsecret




Review the rsyslog.conf
documentation for details on selector lines and their filtering.


You have now completed everything necessary to store
syslog messages to the MySQL database. If you would like to
try out a front-end, you might want to look at phpLogCon, which
displays syslog data in a browser. As of this writing, phpLogCon is not
yet a powerful tool, but it's open source, so it might be a starting
point for your own solution.


On Reliability...


Rsyslogd writes syslog messages directly to the database. This
implies that the database must be available at the time of message
arrival. If the database is offline, no space is left or something else
goes wrong - rsyslogd can not write the database record. If rsyslogd is
unable to store a message, it performs one retry. This is helpful if
the database server was restarted. In this case, the previous
connection was broken but a reconnect immediately succeeds. However, if
the database is down for an extended period of time, an immediate retry
does not help.


Message loss in this scenario can easily be prevented with
rsyslog. All you need to do is run the database writer in queued mode.
This is now described in a generic way and I do not intend to duplicate
it here. So please be sure to read "Handling a massive
syslog database insert rate with Rsyslog", which describes
the scenario and also includes configuration examples.


Conclusion


With minimal effort, you can use rsyslogd to write syslog
messages to a MySQL database. You can even make it absolutely fail-safe
and protect it against database server downtime. Once the messages are
arrived there, you
can interactivley review and analyse them. In practice, the messages
are also stored in text files for longer-term archival and the
databases are cleared out after some time (to avoid becoming too slow).
If you expect an extremely high syslog message volume, storing it in
real-time to the database may outperform your database server. In such
cases, either filter out some messages or used queued mode (which in
general is recommended with databases).


The method outlined in this paper provides an easy to setup
and maintain solution for most use cases.

/* Lex file for rsyslog config format v2 (RainerScript).

* but IMHO still sufficiently easy both to understand for programmers
* maitaining the code as well as users writing the config file. Users are,
* of course, encouraged to use new constructs only. But it needs to be noted
* that some of the legacy constructs (specifically the in-front-of-action
* PRI filter) are very hard to beat in ease of use, at least for simpler
* cases. So while we hope that cfsysline support can be dropped some time in
* the future, we will probably keep these useful constructs.

       for details.  YYERROR is fine as it does not invoke this
       function.
     - If this state is a consistent state with a default action, then
       the only way this function was invoked is if the default action
       is an error action.  In that case, don't check for expected
       tokens because there are none.
     - The only way there can be no lookahead present (in yychar) is if
       this state is a consistent state with a default action.  Thus,
       detecting the absence of a lookahead is sufficient to determine
       that there is no unexpected or expected token to report.  In that
       case, just report a simple "syntax error".
     - Don't assume there isn't a lookahead just because this state is a
       consistent state with a default action.  There might have been a
       previous inconsistent state, consistent state with a non-default
       action, or user semantic action that manipulated yychar.
     - Of course, the expected token list depends on states to have
       correct lookahead information, and it depends on the parser not
       to perform extra reductions after fetching a lookahead from the
       scanner and before detecting a syntax error.  Thus, state merging
       (from LALR or IELR) and default reductions corrupt the expected
       token list.  However, the list is correct for canonical LR with
       one exception: it will still contain any token that will not be
       accepted due to an error action in a later state.

 *
 * This file implements a generic object "class". All other classes can
 * use the service of this base class here to include auto-destruction and
 * other capabilities in a generic manner.
 *
 * As of 2008-02-29, I (rgerhards) am adding support for dynamically loadable
 * objects. In essence, each object will soon be available via its interface,
 * only. Before any object's code is accessed (including global static methods),
 * the caller needs to obtain an object interface. To do so, it needs to provide
 * the object name and the file where the object is expected to reside in. A
 * file may not be given, in which case the object is expected to reside in
 * the rsyslog core. The caller than receives an interface pointer which can
 * be utilized to access all the object's methods. This method enables rsyslog
 * to load library modules on demand. In order to keep overhead low, callers
 * should request object interface only once in the object Init function and
 * free them when they exit. The only exception is when a caller needs to
 * access an object only conditional, in which case a pointer to its interface
 * shall be aquired as need first arises but still be released only on exit
 * or when there definitely is no further need. The whole idea is to limit
 * the very performance-intense act of dynamically loading an objects library.
 * Of course, it is possible to violate this suggestion, but than you should
 * have very good reasoning to do so.
 *
 * Please note that there is one trick we need to do. Each object queries
 * the object interfaces and it does so via objUse(). objUse, however, is
 * part of the obj object's interface (implemented via the file you are
 * just reading). So in order to obtain a pointer to objUse, we need to
 * call it - obviously not possible. One solution would be that objUse is
 * hardcoded into all callers. That, however, would bring us into slight
 * trouble with actually dynamically loaded modules, as we should NOT
 * rely on the OS loader to resolve symbols back to the caller (this
 * is a feature not universally available and highly importable). Of course,
 * we can solve this with a pHostQueryEtryPoint() call. It still sounds
 * somewhat unnatural to call a regular interface function via a special
 * method. So what we do instead is define a special function called
 * objGetObjInterface() which delivers our own interface. That function
 * than will be defined global and be queriable via pHostQueryEtryPoint().
 * I agree, technically this is much the same, but from an architecture
 * point of view it looks cleaner (at least to me).
 * 
 * Please note that there is another egg-hen problem: we use a linked list,
 * which is provided by the linkedList object. However, we need to
 * initialize the linked list before we can provide the UseObj()
 * functionality. That, in turn, would probably be required by the 
 * linkedList object. So the solution is to use a backdoor just to
 * init the linked list and from then on use the usual interfaces.

  Reference implementation of a few systemd related interfaces for
  writing daemons. These interfaces are trivial to implement. To
  simplify porting we provide this reference implementation.
  Applications are welcome to reimplement the algorithms described
  here if they do not want to include these two source files.

  The following functionality is provided:

  - Support for logging with log levels on stderr
  - File descriptor passing for socket-based activation
  - Daemon startup and status notification
  - Detection of systemd boots

  You may compile this with -DDISABLE_SYSTEMD to disable systemd
  support. This makes all those calls NOPs that are directly related to
  systemd (i.e. only sd_is_xxx() will stay useful).

  Since this is drop-in code we don't want any of our symbols to be
  exported in any case. Hence we declare hidden visibility for all of
  them.

  You may find an up-to-date version of these source files online:

  http://cgit.freedesktop.org/systemd/systemd/plain/src/systemd/sd-daemon.h
  http://cgit.freedesktop.org/systemd/systemd/plain/src/libsystemd-daemon/sd-daemon.c

  This should compile on non-Linux systems, too, but with the
  exception of the sd_is_xxx() calls all functions will become NOPs.

  See sd-daemon(3) for more information.

/*
  Informs systemd about changed daemon state. This takes a number of
  newline separated environment-style variable assignments in a
  string. The following variables are known:

     READY=1      Tells systemd that daemon startup is finished (only
                  relevant for services of Type=notify). The passed
                  argument is a boolean "1" or "0". Since there is
                  little value in signaling non-readiness the only
                  value daemons should send is "READY=1".

     STATUS=...   Passes a single-line status string back to systemd
                  that describes the daemon state. This is free-from
                  and can be used for various purposes: general state
                  feedback, fsck-like programs could pass completion
                  percentages and failing programs could pass a human
                  readable error message. Example: "STATUS=Completed
                  66% of file system check..."

     ERRNO=...    If a daemon fails, the errno-style error code,
                  formatted as string. Example: "ERRNO=2" for ENOENT.

     BUSERROR=... If a daemon fails, the D-Bus error-style error
                  code. Example: "BUSERROR=org.freedesktop.DBus.Error.TimedOut"

     MAINPID=...  The main pid of a daemon, in case systemd did not
                  fork off the process itself. Example: "MAINPID=4711"

     WATCHDOG=1   Tells systemd to update the watchdog timestamp.
                  Services using this feature should do this in
                  regular intervals. A watchdog framework can use the
                  timestamps to detect failed services.

  Daemons can choose to send additional variables. However, it is
  recommended to prefix variable names not listed above with X_.

  Returns a negative errno-style error code on failure. Returns > 0
  if systemd could be notified, 0 if it couldn't possibly because
  systemd is not running.

  Example: When a daemon finished starting up, it could issue this
  call to notify systemd about it:

     sd_notify(0, "READY=1");

  See sd_notifyf() for more complete examples.

  See sd_notify(3) for more information.
*/
int sd_notify(int unset_environment, const char *state);

/*
  Similar to sd_notify() but takes a format string.

  Example 1: A daemon could send the following after initialization:

     sd_notifyf(0, "READY=1\n"
                   "STATUS=Processing requests...\n"
                   "MAINPID=%lu",
                   (unsigned long) getpid());

  Example 2: A daemon could send the following shortly before
  exiting, on failure:

     sd_notifyf(0, "STATUS=Failed to start up: %s\n"
                   "ERRNO=%i",
                   strerror(errno),
                   errno);

  See sd_notifyf(3) for more information.

  Returns > 0 if the system was booted with systemd. Returns < 0 on
  error. Returns 0 if the system was not booted with systemd. Note
  that all of the functions above handle non-systemd boots just
  fine. You should NOT protect them with a call to this function. Also

 * Read block parameters. This detects if the block contains the

 * block paramters (from the signature block). As we do not have any
 * begin of block record, we do not know e.g. the hash algorithm or IV
 * until reading the block signature record. And because the file is
 * purely sequential and variable size, we need to read all records up to
 * the next signature record.
 * If a caller intends to verify a log file based on the parameters,
 * he must re-read the file from the begining (we could keep things
 * in memory, but this is impractical for large blocks). In order
 * to facitate this, the function permits to rewind to the original

/* Macros may be used to define type-safe(r) hashtable access functions, with
 * methods specialized to take known key and value types as parameters.
 * 
 * Example:
 *
 * Insert this at the start of your file:
 *
 * DEFINE_HASHTABLE_INSERT(insert_some, struct some_key, struct some_value);
 * DEFINE_HASHTABLE_SEARCH(search_some, struct some_key, struct some_value);
 * DEFINE_HASHTABLE_REMOVE(remove_some, struct some_key, struct some_value);
 *
 * This defines the functions 'insert_some', 'search_some' and 'remove_some'.
 * These operate just like hashtable_insert etc., with the same parameters,
 * but their function signatures have 'struct some_key *' rather than
 * 'void *', and hence can generate compile time errors if your program is
 * supplying incorrect data as a key (and similarly for value).
 *
 * Note that the hash and key equality functions passed to create_hashtable
 * still take 'void *' parameters instead of 'some key *'. This shouldn't be
 * a difficult issue as they're only defined and passed once, and the other
 * functions will ensure that only valid keys are supplied to them.
 *
 * The cost for this checking is increased code size and runtime overhead
 * - if performance is important, it may be worth switching back to the
 * unsafe methods once your program has been debugged with the safe methods.
 * This just requires switching to some simple alternative defines - eg:
 * #define insert_some hashtable_insert
 *

/* macros to handle stats counters
 * These are to be used by "counter providers". Note that we MUST
 * specify the mutex name, even though at first it looks like it
 * could be automatically be generated via e.g. "mut##ctr". 
 * Unfortunately, this does not work if counter is e.g. "pThis->ctr".
 * So we decided, for clarity, to always insist on specifying the mutex
 * name (after all, it's just a few more keystrokes...).
 * --------------------------------------------------------------------
 *                               NOTE WELL
 * --------------------------------------------------------------------
 * There are actually two types of stats counters: "regular" counters,
 * which are only used for stats purposes and "dual" counters, which 
 * are primarily used for other purposes but can be included in stats
 * as well. ALL regular counters MUST be initialized with
 * STATSCOUNTER_INIT and only be modified by STATSCOUNTER_* functions.
 * They MUST NOT be used for any other purpose (if this seems to make
 * sense, consider changing it to a dual counter).
 * Dual counters are somewhat dangerous in that a single variable is
 * used for two purposes: the actual application need and stats
 * counting. However, this is supported for performance reasons, as it
 * provides insight into the inner engine workings without need for
 * additional counters (and their maintenance code). Dual counters
 * MUST NOT be modified by STATSCOUNTER_* functions. Most importantly,
 * it is expected that the actua application code provides proper
 * (enough) synchronized access to these counters. Most importantly,
 * this means they have NO stats-system mutex associated to them.
 *
 * The interface function AddCounter() is a read-only function. It 
 * only provides the stats subsystem with a reference to a counter.
 * It is irrelevant if the counter is a regular or dual one. For that
 * reason, AddCounter() must not modify the counter contents, as in
 * the case of a dual counter application code may be broken.

 *
 * This module relies heavily on preprocessor macros in order to
 * provide fast execution time AND ease of use.
 *
 * Each object that uses this base class MUST provide a constructor with
 * the following interface:
 *
 * Destruct(pThis);
 *
 * A constructor is not necessary (except for some features, e.g. de-serialization).
 * If it is provided, it is a three-part constructor (to handle all cases with a
 * generic interface):
 *
 * Construct(&pThis);
 * SetProperty(pThis, property_t *);
 * ConstructFinalize(pThis);
 *
 * SetProperty() and ConstructFinalize() may also be called on an object
 * instance which has been Construct()'ed outside of this module.
 *
 * pThis always references to a pointer of the object.

 * Large modifications in 2009-06 to support using it with omfile, including zip writer.
 * Note that this file obtains the zlib wrapper object is needed, but it never frees it
 * again. While this sounds like a leak (and one may argue it actually is), there is no
 * harm associated with that. The reason is that strm is a core object, so it is terminated
 * only when rsyslogd exists. As we could only release on termination (or else bear more 
 * overhead for keeping track of how many users we have), not releasing zlibw is OK, because
 * it will be released when rsyslogd terminates. We may want to revisit this decision if
 * it turns out to be problematic. Then, we need to quasi-refcount the number of accesses

 * properties are destroyed when they are no longer needed.
 *
 * Please note that this is a performance-critical part of the software and
 * as such we may use some methods in here which do not look elegant, but

 *
 * The interface data type must always be called _if_t, as this is expected

 * macros create a static variable named like the object in each calling objects

 *
 * This module contains all function which work on a RTL global level. It's
 * name is abbreviated to "rsrt" (rsyslog runtime).
 *
 * Please note that the runtime library tends to be plugin-safe. That is, it must be
 * initialized by calling a global initialization function. However, that 
 * function checks if the library is already initialized and, if so, does
 * nothing except incrementing a refeence count. Similarly, the deinit
 * function does nothing as long as there are still other users (which
 * is tracked via the refcount). As such, it is safe to call init and
 * exit multiple times, as long as this are always matching calls. This
 * capability is needed for a plugin system, where one plugin never
 * knows what the other did. HOWEVER, as of this writing, not all runtime
 * library objects may work cleanly without static global data (the
 * debug system is a very good example of this). So while we aim at the
 * ability to work well in a plugin environment, things may not really work
 * out. If you intend to use the rsyslog runtime library inside plugins,
 * you should investigate the situation in detail. Please note that the
 * rsyslog project itself does not yet need this functionality - thus you
 * can safely assume it is totally untested ;).
 *
 * rgerhards, 2008-04-17: I have now once again checked on the plugin-safety.
 * Unfortunately, there is currently no hook at all with which we could
 * abstract a global data instance class. As such, we can NOT make the
 * runtime plugin-safe in the above-described sense. As the rsyslog
 * project itself does not need this functionality (and it is quesationable
 * if someone else ever will), we do currently do not make an effort to
 * support it. So if you intend to use rsyslog runtime inside a non-rsyslog
 * plugin system, be careful!
 *
 * The rsyslog runtime library is in general reentrant and thread-safe. There
 * are some intentional exceptions (e.g. inside the msg object). These are
 * documented. Any other threading and reentrency issue can be considered a bug.

 * modules can be kept rather simple and without any extra overhead. Note that
 * to support this, tcps_sess.c would need to extract the message reception state
 * machine to a separate module which then is called via the DoCharRcvd() interface
 * of this class here. -- rgerhards, 2009-06-01

 * Implementation of network-related stuff.
 *
 * File begun on 2007-07-20 by RGerhards (extracted from syslogd.c)
 * This file is under development and has not yet arrived at being fully
 * self-contained and a real object. So far, it is mostly an excerpt
 * of the "old" networking code without any modifications. However, it
 * helps to have things at the right place one we go to the meat of it.
 *
 * Starting 2007-12-24, I have begun to shuffle more network-related code
 * from syslogd.c to over here. I am not sure if it will stay here in the
 * long term, but it is good to have it out of syslogd.c. Maybe this here is
 * an interim location ;)
 *
 * Copyright 2007-2011 Rainer Gerhards and Adiscon GmbH.
 *
 * rgerhards, 2008-04-16: I changed this code to LGPL today. I carefully analyzed
 * that it does not borrow code from the original sysklogd and that I have 
 * permission to do so from all other contributors. My analysis found that all
 * code from sysklogd has been superseeded by our own functionality, so it 
 * is OK to move this file to LGPL. Some variable sysklogd variable names
 * remain, but even this will change as the net object evolves.

/* This is common code for all Constructors. It is defined in an

 * An object constructed via this function should only be destroyed
 * via "msgDestruct()". This constructor does not query system time
 * itself but rather uses a user-supplied value. This enables the caller
 * to do some tricks to save processing time (done, for example, in the
 * udp input).
 * NOTE: this constructor does NOT call calloc(), as we have many bytes
 * inside the structure which do not need to be cleared. bzero() will
 * heavily thrash the cache, so we do the init manually (which also
 * is the right thing to do with pointers, as they are not neccessarily
 * a binary 0 on all machines [but today almost always...]).

 * Parameter "bMustBeFreed" is set by this function. It tells the
 * caller whether or not the string returned must be freed by the
 * caller itself. It is is 0, the caller MUST NOT free it. If it is
 * 1, the caller MUST free it. Handling this wrongly leads to either
 * a memory leak of a program abort (do to double-frees or frees on
 * the constant memory pool). So be careful to do it right.

 * regular expression support contributed by Andres Riancho merged
 * on 2005-09-13
 * changed so that it now an be called without a template entry (NULL).
 * In this case, only the (unmodified) property is returned. This will
 * be used in selector line processing.

 * We need to store some additional information in support of encryption.
 * For this, we create a side-file, which is named like the actual log
 * file, but with the suffix ".encinfo" appended. It contains the following
 * records:
 * IV:   The initial vector used at block start. Also indicates start
 *            start of block.
 * END:  The end offset of the block, as uint64_t in decimal notation.
 *            This is used during encryption to know when the current
 *            encryption block ends.
 * For the current implementation, there must always be an IV record
 * followed by an END record. Each records is LF-terminated. Record
 * types can simply be extended in the future by specifying new 
 * types (like "IV") before the colon.
 * To identify a file as rsyslog encryption info file, it must start with
 * the line "FILETYPE:rsyslog-enrcyption-info"
 * There are some size constraints: the recordtype must be 31 bytes at
 * most and the actual value (between : and LF) must be 1023 bytes at most.

 *
 * This file implements the queue object and its several queueing methods.
 * 
 * File begun on 2008-01-03 by RGerhards
 *
 * There is some in-depth documentation available in doc/dev_queue.html
 * (and in the web doc set on http://www.rsyslog.com/doc). Be sure to read it
 * if you are getting aquainted to the object.
 *
 * NOTE: as of 2009-04-22, I have begin to remove the qqueue* prefix from static
 * function names - this makes it really hard to read and does not provide much
 * benefit, at least I (now) think so...

 * Please note that this function shuts down BOTH the parent AND the child queue

 * importantly, the timeouts would be applied twice (or logic be extremely
 * complex) if each would have its own shutdown. The function does not self check

 * rgerhards, 2009-05-26: we do NO longer persist the queue here if bSaveOnShutdown
 * is set. This must be handled by the caller. Not doing that cleans up the queue
 * shutdown considerably. Also, older engines had a potential hang condition when
 * the DA queue was already started and the DA worker configured for infinite
 * retries and the action was during retry processing. This was a design issue,
 * which is solved as of now. Note that the shutdown now may take a little bit
 * longer, because we no longer can persist the queue in parallel to waiting

	 * support. Enhanced flow control is being added today. There are some sources which
	 * can easily be stopped, e.g. a file reader. This is the case because it is unlikely
	 * that blocking those sources will have negative effects (after all, the file is
	 * continued to be written). Other sources can somewhat be blocked (e.g. the kernel
	 * log reader or the local log stream reader): in general, nothing is lost if messages
	 * from these sources are not picked up immediately. HOWEVER, they can not block for
	 * an extended period of time, as this either causes message loss or - even worse - some
	 * other bad effects (e.g. unresponsive system in respect to the main system log socket).
	 * Finally, there are some (few) sources which can not be blocked at all. UDP syslog is
	 * a prime example. If a UDP message is not received, it is simply lost. So we can't
	 * do anything against UDP sockets that come in too fast. The core idea of advanced
	 * flow control is that we take into account the different natures of the sources and
	 * select flow control mechanisms that fit these needs. This also means, in the end
	 * result, that non-blockable sources like UDP syslog receive priority in the system.

 * 
 * This class implements a generic netstrmwork stream class. It supports
 * sending and receiving data streams over a netstrmwork. The class abstracts
 * the transport, though it is a safe assumption that TCP is being used.
 * The class has a number of properties, among which are also ones to
 * select privacy settings, eg by enabling TLS and/or GSSAPI. In the 
 * long run, this class shall provide all stream-oriented netstrmwork
 * functionality inside rsyslog.
 *
 * It is a high-level class, which uses a number of helper objects
 * to carry out its work (including, and most importantly, transport
 * drivers).

 *
 * A serial stream provides serial data access. In theory, serial streams
 * can be implemented via a number of methods (e.g. files or in-memory
 * streams). In practice, there currently only exist the file type (aka
 * "driver").
 *
 * In practice, many stream features are bound to files. I have not yet made
 * any serious effort, except for the naming of this class, to try to make
 * the interfaces very generic. However, I assume that we could work much
 * like in the strm class, where some properties are simply ignored when
 * the wrong strm mode is selected (which would translate here to the wrong
 * stream mode).
 *
 * Most importantly, this class provides generic input and output functions
 * which can directly be used to work with the strms and file output. It
 * provides such useful things like a circular file buffer and, hopefully
 * at a later stage, a lazy writer. The object is also seriazable and thus
 * can easily be persistet. The bottom line is that it makes much sense to
 * use this class whereever possible as its features may grow in the future.
 *
 * An important note on writing gzip format via zlib (kept anonymous
 * by request):
 *
 * --------------------------------------------------------------------------
 * We'd like to make sure the output file is in full gzip format
 * (compatible with gzip -d/zcat etc).  There is a flag in how the output
 * is initialized within zlib to properly add the gzip wrappers to the
 * output.  (gzip is effectively a small metadata wrapper around raw
 * zstream output.)
 * 
 * I had written an old bit of code to do this - the documentation on
 * deflatInit2() was pretty tricky to nail down on this specific feature:
 * 
 * int deflateInit2 (z_streamp strm, int level, int method, int windowBits,
 * int memLevel, int strategy);
 * 
 * I believe "31" would be the value for the "windowBits" field that you'd
 * want to try:
 * 
 * deflateInit2(zstrmptr, 6, Z_DEFLATED, 31, 9, Z_DEFAULT_STRATEGY);

directly relate to rsyslog. They are not actively supported, but as
I said often helpful. Use them with some care, as they may be outdated
in respect to the current release of rsyslog.

At least some of this stuff has been found by our users and been
included after a brief check and possibly an adapation. If you have
something useful you would like to see in contrib, just drop us a 
note (see http://www.rsyslog.com for how to do that at the time your
are reading this document).

.SH DESCRIPTION
.B Rsyslogd
is a system utility providing support for message logging.
Support of both internet and
unix domain sockets enables this utility to support both local
and remote logging.

.B Note that this version of rsyslog ships with extensive documentation in html format.
This is provided in the ./doc subdirectory and probably
in a separate package if you installed rsyslog via a packaging system.
To use rsyslog's advanced features, you
.B need
to look at the html documentation, because the man pages only cover
basic aspects of operation.
.B For details and configuration examples, see the rsyslog.conf (5)
.B man page and the online documentation at http://www.rsyslog.com/doc

.BR Rsyslogd (8)
is derived from the sysklogd package which in turn is derived from the
stock BSD sources.

.B Rsyslogd
provides a kind of logging that many modern programs use.  Every logged
message contains at least a time and a hostname field, normally a
program name field, too, but that depends on how trusty the logging
program is. The rsyslog package supports free definition of output formats
via templates. It also supports precise timestamps and writing directly
to databases. If the database option is used, tools like phpLogCon can
be used to view the log data.

While the
.B rsyslogd
sources have been heavily modified a couple of notes
are in order.  First of all there has been a systematic attempt to
ensure that rsyslogd follows its default, standard BSD behavior. Of course,
some configuration file changes are necessary in order to support the
template system. However, rsyslogd should be able to use a standard
syslog.conf and act like the original syslogd. However, an original syslogd
will not work correctly with a rsyslog-enhanced configuration file. At
best, it will generate funny looking file names.
The second important concept to note is that this version of rsyslogd
interacts transparently with the version of syslog found in the
standard libraries.  If a binary linked to the standard shared
libraries fails to function correctly we would like an example of the
anomalous behavior.

The main configuration file
.I /etc/rsyslog.conf
or an alternative file, given with the 
.B "\-f"
option, is read at startup.  Any lines that begin with the hash mark
(``#'') and empty lines are ignored.  If an error occurs during parsing
the error element is ignored. It is tried to parse the rest of the line.

.LP
.SH OPTIONS
.TP
.BI "\-A"
When sending UDP messages, there are potentially multiple paths to
the target destination. By default,
.B rsyslogd
only sends to the first target it can successfully send to. If -A 
is given, messages are sent to all targets. This may improve
reliability, but may also cause message duplication. This option
should be enabled only if it is fully understood.
.TP
.BI "\-4"
Causes
.B rsyslogd
to listen to IPv4 addresses only.
If neither -4 nor -6 is given,
.B rsyslogd
listens to all configured addresses of the system.
.TP
.BI "\-6"
Causes
.B rsyslogd
to listen to IPv6 addresses only.
If neither -4 nor -6 is given,
.B rsyslogd
listens to all configured addresses of the system.
.TP
.BI "\-c " "version"
This option has been obsoleted and has no function any longer. It is still
accepted in order not to break existing scripts. However, future versions
may not support it.
.TP
.B "\-D"
Runs the Bison config parser in debug mode. This may help when hard to find
syntax errors are reported. Please note that the output generated is deeply
technical and orignally targeted towards developers.
.TP
.B "\-d"
Turns on debug mode.  Using this the daemon will not proceed a 
.BR fork (2)
to set itself in the background, but opposite to that stay in the
foreground and write much debug information on the current tty.  See the
DEBUGGING section for more information.
.TP
.BI "\-f " "config file"
Specify an alternative configuration file instead of
.IR /etc/rsyslog.conf ","
which is the default.
.TP
.BI "\-i " "pid file"
Specify an alternative pid file instead of the default one.
This option must be used if multiple instances of rsyslogd should
run on a single machine.
.TP
.BI "\-l " "hostlist"
Specify a hostname that should be logged only with its simple hostname
and not the fqdn.  Multiple hosts may be specified using the colon
(``:'') separator.
.TP
.B "\-n"
Avoid auto-backgrounding.  This is needed especially if the
.B rsyslogd
is started and controlled by
.BR init (8).
.TP
.B "\-N " "level"
Do a coNfig check. Do NOT run in regular mode, just check configuration
file correctness.
This option is meant to verify a config file. To do so, run rsyslogd
interactively in foreground, specifying -f  and -N level.
The level argument modifies behaviour. Currently, 0 is the same as
not specifying the -N option at all (so this makes limited sense) and
1 actually activates the code. Later, higher levels will mean more
verbosity (this is a forward-compatibility option).
.B rsyslogd
is started and controlled by
.BR init (8).
.TP
.BI "\-q " "add hostname if DNS fails during ACL processing"
During ACL processing, hostnames are resolved to IP addresses for
performance reasons. If DNS fails during that process, the hostname
is added as wildcard text, which results in proper, but somewhat
slower operation once DNS is up again.
.TP
.BI "\-Q " "do not resolve hostnames during ACL processing"
Do not resolve hostnames to IP addresses during ACL processing.
.TP
.BI "\-s " "domainlist"
Specify a domainname that should be stripped off before
logging.  Multiple domains may be specified using the colon (``:'')
separator.
Please be advised that no sub-domains may be specified but only entire
domains.  For example if
.B "\-s north.de"
is specified and the host logging resolves to satu.infodrom.north.de
no domain would be cut, you will have to specify two domains like:
.BR "\-s north.de:infodrom.north.de" .
.TP
.BI "\-u " "userlevel"
This is a "catch all" option for some very seldomly-used user settings.
The "userlevel" variable selects multiple things. Add the specific values
to get the combined effect of them.
A value of 1 prevents rsyslogd from parsing hostnames and tags inside
messages.
A value of 2 prevents rsyslogd from changing to the root directory. This
is almost never a good idea in production use. This option was introduced
in support of the internal testbed.
To combine these two features, use a userlevel of 3 (1+2). Whenever you use
an -u option, make sure you really understand what you do and why you do it.
.TP
.B "\-v"
Print version and exit.
.TP
.B "\-w"
Suppress warnings issued when messages are received from non-authorized
machines (those, that are in no AllowedSender list).
.TP
.B "\-x"
Disable DNS for remote messages.
.LP
.SH SIGNALS
.B Rsyslogd
reacts to a set of signals.  You may easily send a signal to
.B rsyslogd
using the following:
.IP
.nf
kill -SIGNAL $(cat /var/run/rsyslogd.pid)
.fi
.PP
Note that -SIGNAL must be replaced with the actual signal
you are trying to send, e.g. with HUP. So it then becomes:
.IP
.nf
kill -HUP $(cat /var/run/rsyslogd.pid)
.fi
.PP
.TP
.B HUP
This lets
.B rsyslogd
perform close all open files.
Also, in v3 a full restart will be done in order to read changed configuration files.
Note that this means a full rsyslogd restart is done. This has, among others,
the consequence that TCP and other connections are torn down. Also, if any
queues are not running in disk assisted mode or are not set to persist data
on shutdown, queue data is lost. HUPing rsyslogd is an extremely expensive
operation and should only be done when actually necessary. Actually, it is
a rsyslgod stop immediately followed by a restart. Future versions will remove
this restart functionality of HUP (it will go away in v5). So it is advised to use
HUP only for closing files, and a "real restart" (e.g. /etc/rc.d/rsyslogd restart)
to activate configuration changes.
.TP
.B TERM ", " INT ", " QUIT
.B Rsyslogd
will die.
.TP
.B USR1
Switch debugging on/off.  This option can only be used if
.B rsyslogd
is started with the
.B "\-d"
debug option.
.TP
.B CHLD
Wait for childs if some were born, because of wall'ing messages.
.LP
.SH SECURITY THREATS
There is the potential for the rsyslogd daemon to be
used as a conduit for a denial of service attack.
A rogue program(mer) could very easily flood the rsyslogd daemon with
syslog messages resulting in the log files consuming all the remaining
space on the filesystem.  Activating logging over the inet domain
sockets will of course expose a system to risks outside of programs or
individuals on the local machine.

There are a number of methods of protecting a machine:
.IP 1.
Implement kernel firewalling to limit which hosts or networks have
access to the 514/UDP socket.
.IP 2.
Logging can be directed to an isolated or non-root filesystem which,
if filled, will not impair the machine.
.IP 3.
The ext2 filesystem can be used which can be configured to limit a
certain percentage of a filesystem to usage by root only.  \fBNOTE\fP
that this will require rsyslogd to be run as a non-root process.
\fBALSO NOTE\fP that this will prevent usage of remote logging on the default port since
rsyslogd will be unable to bind to the 514/UDP socket.
.IP 4.
Disabling inet domain sockets will limit risk to the local machine.
.SS Message replay and spoofing
If remote logging is enabled, messages can easily be spoofed and replayed.
As the messages are transmitted in clear-text, an attacker might use
the information obtained from the packets for malicious things. Also, an
attacker might replay recorded messages or spoof a sender's IP address,
which could lead to a wrong perception of system activity. These can
be prevented by using GSS-API authentication and encryption. Be sure
to think about syslog network security before enabling it.
.LP
.SH DEBUGGING
When debugging is turned on using
.B "\-d"
option then
.B rsyslogd
will be very verbose by writing much of what it does on stdout.
.SH FILES
.PD 0
.TP
.I /etc/rsyslog.conf
Configuration file for
.BR rsyslogd .
See
.BR rsyslog.conf (5)
for exact information.
.TP
.I /dev/log
The Unix domain socket to from where local syslog messages are read.
.TP
.I /var/run/rsyslogd.pid
The file containing the process id of 
.BR rsyslogd .
.TP
.I prefix/lib/rsyslog
Default directory for
.B rsyslogd
modules. The
.I prefix
is specified during compilation (e.g. /usr/local).
.SH ENVIRONMENT
.TP
.B RSYSLOG_DEBUG
Controls runtime debug support.It contains an option string with the
following options possible (all are case insensitive):

.RS
.IP LogFuncFlow
Print out the logical flow of functions (entering and exiting them)
.IP FileTrace
Specifies which files to trace LogFuncFlow. If not set (the
default), a LogFuncFlow trace is provided for all files. Set to
limit it to the files specified.FileTrace may be specified multiple
times, one file each (e.g. export RSYSLOG_DEBUG="LogFuncFlow
FileTrace=vm.c FileTrace=expr.c"
.IP PrintFuncDB
Print the content of the debug function database whenever debug
information is printed (e.g. abort case)!
.IP PrintAllDebugInfoOnExit
Print all debug information immediately before rsyslogd exits
(currently not implemented!)
.IP PrintMutexAction
Print mutex action as it happens. Useful for finding deadlocks and
such.
.IP NoLogTimeStamp
Do not prefix log lines with a timestamp (default is to do that).
.IP NoStdOut
Do not emit debug messages to stdout. If RSYSLOG_DEBUGLOG is not
set, this means no messages will be displayed at all.
.IP Help
Display a very short list of commands - hopefully a life saver if
you can't access the documentation...
.RE

.TP
.B RSYSLOG_DEBUGLOG
If set, writes (almost) all debug message to the specified log file
in addition to stdout.
.TP
.B RSYSLOG_MODDIR
Provides the default directory in which loadable modules reside.
.PD

 * \brief This is the main file of the rsyslogd daemon.
 *
 * Please visit the rsyslog project at
 *
 * http://www.rsyslog.com
 *
 * to learn more about it and discuss any questions you may have.
 *
 * rsyslog had initially been forked from the sysklogd project.
 * I would like to express my thanks to the developers of the sysklogd
 * package - without it, I would have had a much harder start...
 *
 * Please note that while rsyslog started from the sysklogd code base,
 * it nowadays has almost nothing left in common with it. Allmost all
 * parts of the code have been rewritten.
 *
 * This Project was intiated and is maintained by
 * Rainer Gerhards .

 * This is a strgen module for the traditional file format.

 * Format generated:
 * "%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
 * Note that this is the same as smtradfile.c, except that we do have a RFC3339 timestamp. However,
 * we have copied over the code from there, it is too simple to go through all the hassle
 * of having a single code base.

Manage (GuardTime) Signed Log Files
-----------------------------------

:Author: Rainer Gerhards 
:Date: 2013-03-25
:Manual section: 1

SYNOPSIS
========

::

   rsgtutil [OPTIONS] [FILE] ...


DESCRIPTION
===========

This tool performs various maintenance operations on signed log files.
It specifically supports the GuardTime signature provider.

The *rsgtutil* tool is the primary tool to verify log file signatures,
dump signature file contents and carry out other maintenance operations.
The tool offers different operation modes, which are selected via
command line options.

The processing of multiple files is permitted. Depending on operation
mode, either the signature file or the base log file must be specified.
Within a single call, only a single operations mode is permitted. To 
use different modes on different files, multiple calles, one for each
mode, must be made.

If no file is specified on the command line, stdin is used instead. Note
that not all operation modes support stdin.

OPTIONS
=======

-D, --dump
  Select "dump" operations mode.

-t, --verify
  Select "verify" operations mode.

-T, --detect-file-type
  Select "detect-file-type" operations mode.

-B, --show-sigblock-params
  Select "show-sigblock-params" operations mode.

-s, --show-verified
  Prints out information about correctly verified blocks (by default, only
  errors are printed).

-v, --verbose
  Select verbose mode. Most importantly, hashes and signatures are printed
  in full length (can be **very** lengthy) rather than the usual abbreviation.

-e, --extend
  Select extend mode. This extends the RFC3161 signatures. Note that this
  mode also implies a full verification. If there are verify errors, extending
  will also fail.

-P , --publications-server 
  Sets the publications server. If not set but required by the operation a
  default server is used. The default server is not necessarily optimal
  in regard to performance and reliability.


OPERATION MODES
===============

The operation mode specifies what exactly the tool does with the provided
files. The default operation mode is "dump", but this may change in the future.
Thus, it is recommended to always set the operations mode explicitely. If 
multiple operations mode are set on the command line, results are 
unpredictable.

dump
----

The provided *signature* files are dumped. For each top-level record, the*u
type code is printed as well as q short description. If there is additional
information available, it will be printed in tab-indented lines below the
main record dump. The actual *log* files need not to be present.

verify
------

This mode does not work with stdin. On the command line, the *log* file names
are specified. The corresponding *signature* files (ending on ".gtsig") must also
be preset at the same location as the log file. In verify mode, both the log
and signature file is read and the validity of the log file checked. If verification
errors are detected these are printed and processing of the file aborted. By default,
each file is verified individually, without taking cross-file hash chains into
account (so the order of files on the command line does not matter).

Note that the actual amount of what can be verified depends on the parameters with
which the signature file was written. If record and tree hashes are present, they
will be verified and thus fine-granular error reporting is possible. If they are
not present, only the block signature itself is verified.

By default, only errors are printed. To also print successful verifications, use the
**--show-verified** option.


extend
------
This extends the RFC3161 signatures. This includes a full verification
of the file. If there are verification errors, extending will also fail.
Note that a signature can only be extended when the required hash has been
published. Currently, these hashes are created at the 15th of each month at
0:00hrs UTC. It takes another few days to get them finally published. As such,
it can be assumed that extending is only possible after this happend (which
means it may take slightly above a month).

To prevent data corruption, a copy of the signature file is created during
extension. So there must be enough disk space available for both files,
otherwise the operation will fail. If the log file is named logfile, the
signature file is logfile.gtsig and the temporary work file is named
logfile.gtsig.new. When extending finished successfully, the original
signature file (logfile.gtsig in our example) is renamed with the .old
postfix (logfile.gtsig.old) and the temporary file written under the
original name. The .old file can be deleted. It is just kept as a 
precaution to prevent signature loss. Note that any already existing
.old or .new files are overwritten by these operations.


detect-file-type
----------------
This mode is used to detect the type of some well-know files used inside the 
signature system. The detection is based on the file header. This mode is
primarily a debug aid.


show-sigblock-params
--------------------
This mode is used to print signature block parameters. It is similar to *dump*
mode, but will ignore everything except signature blocks. Also, some additional
meta information is printed. This mode is primarily a debug aid.

EXIT CODES
==========

The command returns an exit code of 0 if everything went fine, and some 
other code in case of failures.


EXAMPLES
========

**rsgtutil --verify logfile**

This verifies the file "logfile" via its associated signature file
"logfile.gtsig". If errors are detected, these are reported to stderr.
Otherwise, rsgtutil terminates without messages.

**rsgtutil --dump logfile.gtsig**

This dumps the content of the signature file "logfile.gtsig". The
actual log file is not being processed and does not even need to be
present.

 * This is the implementation of the build-in file output module.
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!
 *
 * File begun on 2007-07-21 by RGerhards (extracted from syslogd.c, which
 * at the time of the fork from sysklogd was under BSD license)
 *
 * A large re-write of this file was done in June, 2009. The focus was
 * to introduce many more features (like zipped writing), clean up the code
 * and make it more reliable. In short, that rewrite tries to provide a new
 * solid basis for the next three to five years to come. During it, bugs
 * may have been introduced ;) -- rgerhards, 2009-06-04
 *
 * Note that as of 2010-02-28 this module does no longer handle
 * pipes. These have been moved to ompipe, to reduced the entanglement
 * between the two different functionalities. -- rgerhards

/* Version history:
   1.0  30 Oct 2004  First version
   1.1   8 Nov 2004  Add void casting for unused return values
                     Use switch statement for inflate() return values
   1.2   9 Nov 2004  Add assertions to document zlib guarantees
   1.3   6 Apr 2005  Remove incorrect assertion in inf()
   1.4  11 Dec 2005  Add hack to avoid MSDOS end-of-line conversions
                     Avoid some compiler warnings for input and output buffers
   2.0  03 Jun 2009  Add hack to support multiple deflate records inside a single
   		     file on inflate. This is needed in order to support reading
		     files created by rsyslog's zip output writer.

 * This is the implementation of the build-in pipe output module.
 * Note that this module stems back to the "old" (4.4.2 and below)
 * omfile. There were some issues with the new omfile code and pipes
 * (namely in regard to xconsole), so we took out the pipe code and moved
 * that to a separate module. That a) immediately solves the issue for a
 * less common use case and probably makes it much easier to enhance
 * file and pipe support (now independently) in the future (we always
 * needed to think about pipes in omfile so far, what we now no longer
 * need to, hopefully resulting in reduction of complexity).
 *
 * NOTE: read comments in module-template.h to understand how this pipe
 *       works!

Manage Encrypted Log Files
--------------------------

SYNOPSIS
========

::

   rscryutil [OPTIONS] [FILE] ...


DESCRIPTION
===========

This tool performs various operations on encrypted log files.
Most importantly, it provides the ability to decrypt them.


OPTIONS
=======

-d, --decrypt
  Select decryption mode. This is the default mode.

-W, --write-keyfile 
  Utility function to write a key to a keyfile. The key can be obtained
  via any method.

-v, --verbose
  Select verbose mode.

-f, --force
  Forces operations that otherwise would fail.

-k, --keyfile 
  Reads the key from . File _must_ contain the key, only, no headers
  or other meta information. Keyfiles can be generated via the
  *--write-keyfile* option.

-p, --key-program 
 In this mode, the key is provided by a so-called "key program". This program
 is executed and must return the key to (as well as some meta information)
 via stdout. The core idea of key programs is that using this interface the
 user can implement as complex (and secure) method to obtain keys as
 desired, all without the need to make modifications to rsyslog.

-K, --key 
  TESTING AID, NOT FOR PRODUCTION USE. This uses the KEY specified
  on the command line. This is the actual key, and as such this mode
  is highly insecure. However, it can be useful for intial testing
  steps. This option may be removed in the future.

-a, --algo 
  Sets the encryption algorightm (cipher) to be used. See below
  for supported algorithms. The default is "AES128".

-m, --mode 
  Sets the ciphermode to be used. See below for supported modes.
  The default is "CBC".

-r, --generate-random-key 
  Generates a random key of length . This option is
  meant to be used together with *--write-keyfile* (and it is hard
  to envision any other valid use for it).

OPERATION MODES
===============

The operation mode specifies what exactly the tool does with the provided
files. The default operation mode is "dump", but this may change in the future.
Thus, it is recommended to always set the operations mode explicitely. If 
multiple operations mode are set on the command line, results are 
unpredictable.

decrypt
-------

The provided log files are decrypted. Note that the *.encinfo* side files
must exist and be accessible in order for decryption to to work.

write-keyfile
-------------

In this mode no log files are processed; thus it is an error to specify
any on the command line. The specified keyfile is written. The key itself
is obtained via the usual key commands. If *--keyfile* is used, that
file is effectively copied.

For security reasons, existing key files are _not_ overwritten. To permit
this, specify the *--force* option. When doing so, keep in mind that lost
keys cannot be recovered and data encrypted with them may also be considered
lost.

Keyfiles are always created with 0400 permission, that is read access for only
the user. An exception is when an existing file is overwritten via the
*--force* option, in which case the former permissions still apply.

EXIT CODES
==========

The command returns an exit code of 0 if everything went fine, and some 
other code in case of failures.


SUPPORTED ALGORITHMS
====================

We basically support what libgcrypt supports. This is:

	3DES
	CAST5
	BLOWFISH
	AES128
	AES192
	AES256
	TWOFISH
	TWOFISH128
	ARCFOUR
	DES
	SERPENT128
	SERPENT192
	SERPENT256
	RFC2268_40
	SEED
	CAMELLIA128
	CAMELLIA192
	CAMELLIA256


SUPPORTED CIPHER MODES
======================

We basically support what libgcrypt supports. This is:

  	ECB
	CFB
	CBC
	STREAM
	OFB
	CTR
	AESWRAP

EXAMPLES
========

**rscryutil logfile**

Decrypts "logfile" and sends data to stdout.


**rscryutil --generate-random-key 16 --keyfile /some/secured/path/keyfile**

Generates random key and stores it in the specified keyfile.

LOG SIGNATURES
==============

Encrypted log files can be used together with signing. To verify such a file,
it must be decrypted first, and the verification tool **rsgtutil(1)** must be
run on the decrypted file.

SECURITY CONSIDERATIONS
=======================

Specifying keys directly on the command line (*--key* option) is very 
insecure and should
not be done, except for testing purposes with test keys. Even then it is
recommended to use keyfiles, which are also easy to handle during testing.
Keep in mind that command history is usally be kept by bash and can also
easily be monitored.

Local keyfiles are also a security risk. At a minimum, they should be
used with very restrictive file permissions. For this reason,
the *rscryutil* tool creates them with read permissions for the user,
only, no matter what umask is set to.

When selecting cipher algorithms and modes, care needs to be taken. The
defaults should be reasonable safe to use, but this tends to change over
time. Keep up with the most current crypto recommendations.

.ft C
rsgtutil [OPTIONS] [FILE] ...

.SH DESCRIPTION
.sp
This tool performs various maintenance operations on signed log files.
It specifically supports the GuardTime signature provider.
.sp
The \fIrsgtutil\fP tool is the primary tool to verify log file signatures,
dump signature file contents and carry out other maintenance operations.
The tool offers different operation modes, which are selected via
command line options.
.sp
The processing of multiple files is permitted. Depending on operation
mode, either the signature file or the base log file must be specified.
Within a single call, only a single operations mode is permitted. To
use different modes on different files, multiple calles, one for each
mode, must be made.
.sp
If no file is specified on the command line, stdin is used instead. Note
that not all operation modes support stdin.
.SH OPTIONS
.INDENT 0.0
.TP
.B \-D,  \-\-dump
Select "dump" operations mode.
.TP
.B \-t,  \-\-verify
Select "verify" operations mode.
.TP
.B \-T,  \-\-detect\-file\-type
Select "detect\-file\-type" operations mode.
.TP
.B \-B,  \-\-show\-sigblock\-params
Select "show\-sigblock\-params" operations mode.
.TP
.B \-s,  \-\-show\-verified
Prints out information about correctly verified blocks (by default, only
errors are printed).
.TP
.B \-v,  \-\-verbose
Select verbose mode. Most importantly, hashes and signatures are printed
in full length (can be \fBvery\fP lengthy) rather than the usual abbreviation.
.TP
.B \-e,  \-\-extend
Select extend mode. This extends the RFC3161 signatures. Note that this
mode also implies a full verification. If there are verify errors, extending
will also fail.
.TP
.BI \-P \ , \ \-\-publications\-server \ 
Sets the publications server. If not set but required by the operation a
default server is used. The default server is not necessarily optimal
in regard to performance and reliability.
.UNINDENT
.SH OPERATION MODES
.sp
The operation mode specifies what exactly the tool does with the provided
files. The default operation mode is "dump", but this may change in the future.
Thus, it is recommended to always set the operations mode explicitely. If
multiple operations mode are set on the command line, results are
unpredictable.
.SS dump
.sp
The provided \fIsignature\fP files are dumped. For each top\-level record, the*u
type code is printed as well as q short description. If there is additional
information available, it will be printed in tab\-indented lines below the
main record dump. The actual \fIlog\fP files need not to be present.
.SS verify
.sp
This mode does not work with stdin. On the command line, the \fIlog\fP file names
are specified. The corresponding \fIsignature\fP files (ending on ".gtsig") must also
be preset at the same location as the log file. In verify mode, both the log
and signature file is read and the validity of the log file checked. If verification
errors are detected these are printed and processing of the file aborted. By default,
each file is verified individually, without taking cross\-file hash chains into
account (so the order of files on the command line does not matter).
.sp
Note that the actual amount of what can be verified depends on the parameters with
which the signature file was written. If record and tree hashes are present, they
will be verified and thus fine\-granular error reporting is possible. If they are
not present, only the block signature itself is verified.
.sp
By default, only errors are printed. To also print successful verifications, use the
\fB\-\-show\-verified\fP option.
.SS extend
.sp
This extends the RFC3161 signatures. This includes a full verification
of the file. If there are verification errors, extending will also fail.
Note that a signature can only be extended when the required hash has been
published. Currently, these hashes are created at the 15th of each month at
0:00hrs UTC. It takes another few days to get them finally published. As such,
it can be assumed that extending is only possible after this happend (which
means it may take slightly above a month).
.sp
To prevent data corruption, a copy of the signature file is created during
extension. So there must be enough disk space available for both files,
otherwise the operation will fail. If the log file is named logfile, the
signature file is logfile.gtsig and the temporary work file is named
logfile.gtsig.new. When extending finished successfully, the original
signature file (logfile.gtsig in our example) is renamed with the .old
postfix (logfile.gtsig.old) and the temporary file written under the
original name. The .old file can be deleted. It is just kept as a
precaution to prevent signature loss. Note that any already existing
.old or .new files are overwritten by these operations.
.SS detect\-file\-type
.sp
This mode is used to detect the type of some well\-know files used inside the
signature system. The detection is based on the file header. This mode is
primarily a debug aid.
.SS show\-sigblock\-params
.sp
This mode is used to print signature block parameters. It is similar to \fIdump\fP
mode, but will ignore everything except signature blocks. Also, some additional
meta information is printed. This mode is primarily a debug aid.
.SH EXIT CODES
.sp
The command returns an exit code of 0 if everything went fine, and some
other code in case of failures.
.SH EXAMPLES
.sp
\fBrsgtutil \-\-verify logfile\fP
.sp
This verifies the file "logfile" via its associated signature file
"logfile.gtsig". If errors are detected, these are reported to stderr.
Otherwise, rsgtutil terminates without messages.
.sp
\fBrsgtutil \-\-dump logfile.gtsig\fP
.sp
This dumps the content of the signature file "logfile.gtsig". The
actual log file is not being processed and does not even need to be
present.

.SH NAME
rsyslog.conf \- rsyslogd(8) configuration file
.SH DESCRIPTION
The
.I rsyslog.conf
file is the main configuration file for the
.BR rsyslogd (8)
which logs system messages on *nix systems.  This file specifies rules
for logging.  For special features see the
.BR rsyslogd (8)
manpage. Rsyslog.conf is backward-compatible with sysklogd's syslog.conf file. So if you migrate
from sysklogd you can rename it and it should work.

.B Note that this version of rsyslog ships with extensive documentation in html format.
This is provided in the ./doc subdirectory and probably
in a separate package if you installed rsyslog via a packaging system.
To use rsyslog's advanced features, you
.B need
to look at the html documentation, because the man pages only cover
basic aspects of operation.


.SH MODULES

Input plugin for the RELP protocol. RELP can be used instead
of UDP or plain TCP syslog to provide reliable delivery of
syslog messages. Please note that plain TCP syslog does NOT
provide truly reliable delivery, with it messages may be lost
when there is a connection problem or the server shuts down.
RELP prevents message loss in those cases.
It can be used like this:
.IP
$ModLoad imrelp
.IP
$InputRELPServerRun 2514
.TP
.I imgssapi
Input plugin for plain TCP and GSS-enable syslog
.TP
.I immark
Support for mark messages
.TP
.I imklog
Kernel logging. To include kernel log messages, you need to do
.IP
$ModLoad imklog

Please note that the klogd daemon is no longer necessary and consequently
no longer provided by the rsyslog package.
.TP
.I imuxsock
Unix sockets, including the system log socket. You need to specify
.IP
$ModLoad imuxsock

in order to receive log messages from local system processes. This
config directive should only left out if you know exactly what you
are doing.


.SH BASIC STRUCTURE

Lines starting with a hash mark ('#') and empty lines are ignored. 
Rsyslog.conf should contain following sections (sorted by recommended order in file):

.TP
Global directives
Global directives set some global properties of whole rsyslog daemon, for example size of main
message queue ($MainMessageQueueSize), loading external modules ($ModLoad) and so on.
All global directives need to be specified on a line by their own and must start with 
a dollar-sign. The complete list of global directives can be found in html documentation in doc 
directory or online on web pages.

.TP
Templates
Templates allow you to specify format of the logged message. They are also used for dynamic 
file name generation. They have to be defined before they are used in rules. For more info 
about templates see TEMPLATES section of this manpage.

.TP
Output channels
Output channels provide an umbrella for any type of output that the user might want. 
They have to be defined before they are used in rules. For more info about output channels
see OUTPUT CHANNELS section of this manpage.

.TP
Rules (selector + action)
Every rule line consists of two fields, a selector field and an action field. These 
two fields are separated by one or more spaces or tabs. The selector field specifies 
a pattern of facilities and priorities belonging to the specified action.

.SH SELECTORS

The selector field itself again consists of two parts, a facility and a
priority, separated by a period ('.'). Both parts are case insensitive and can
also be specified as decimal numbers, but don't do that, you have been warned.
Both facilities and priorities are described in syslog(3). The names mentioned
below correspond to the similar LOG_-values in /usr/include/syslog.h.

The facility is one of the following keywords: auth, authpriv, cron, daemon,
kern, lpr, mail, mark, news, security (same as auth), syslog, user, uucp and
local0 through local7. The keyword security should not be used anymore and mark
is only for internal use and therefore should not be used in applications.
Anyway, you may want to specify and redirect these messages here. The facility
specifies the subsystem that produced the message, i.e. all mail programs log
with the mail facility (LOG_MAIL) if they log using syslog.

The priority is one of the following keywords, in ascending order: debug, info,
notice, warning, warn (same as warning), err, error (same as err), crit, alert,
emerg, panic (same as emerg). The keywords error, warn and panic are deprecated
and should not be used anymore. The priority defines the severity of the message.

The behavior of the original BSD syslogd is that all messages of the specified
priority and higher are logged according to the given action. Rsyslogd behaves
the same, but has some extensions.

In addition to the above mentioned names the rsyslogd(8) understands the
following extensions: An asterisk ('*') stands for all facilities or all
priorities, depending on where it is used (before or after the period). The
keyword none stands for no priority of the given facility.

You can specify multiple facilities with the same priority pattern in one
statement using the comma (',') operator. You may specify as much facilities as
you want. Remember that only the facility part from such a statement is taken, a
priority part would be skipped.

Multiple selectors may be specified for a single action using the semicolon
(';') separator. Remember that each selector in the selector field is capable
to overwrite the preceding ones. Using this behavior you can exclude some
priorities from the pattern.

Rsyslogd has a syntax extension to the original BSD source, that makes its use
more intuitively. You may precede every priority with an equals sign ('=') to
specify only this single priority and not any of the above. You may also (both
is valid, too) precede the priority with an exclamation mark ('!') to ignore
all that priorities, either exact this one or this and any higher priority. If
you use both extensions than the exclamation mark must occur before the equals
sign, just use it intuitively.

.SH ACTIONS
The action field of a rule describes what to do with the message. In general, message content 
is written to a kind of "logfile". But also other actions might be done, like writing to a 
database table or forwarding to another host.

.SS Regular file
Typically messages are logged to real files. The file has to be specified with full pathname, 
beginning with a slash ('/').

.B Example:
.RS
*.*     /var/log/traditionalfile.log;RSYSLOG_TraditionalFileFormat      # log to a file in the traditional format
.RE

Note: if you would like to use high-precision timestamps in your log files,
just remove the ";RSYSLOG_TraditionalFormat". That will select the default
template, which, if not changed, uses RFC 3339 timestamps.

.B Example:
.RS
*.*     /var/log/file.log # log to a file with RFC3339 timestamps
.RE

.SS Named pipes
This version of rsyslogd(8) has support for logging output to named pipes (fifos). A fifo or 
named pipe can be used as a destination for log messages by prepending a pipe symbol ('|') 
to the name of the file. This is handy for debugging. Note that the fifo must be created with 
the mkfifo(1) command before rsyslogd(8) is started.

.SS Terminal and console
If the file you specified is a tty, special tty-handling is done, same with /dev/console.

.SS Remote machine
There are three ways to forward message: the traditional UDP transport, which is extremely
lossy but standard, the plain TCP based transport which loses messages only during certain
situations but is widely available and the RELP transport which does not lose messages
but is currently available only as part of rsyslogd 3.15.0 and above.

To forward messages to another host via UDP, prepend the hostname with the at sign ("@").
To forward it via plain tcp, prepend two at signs ("@@"). To forward via RELP, prepend the
string ":omrelp:" in front of the hostname.

.B Example:
.RS
*.* @192.168.0.1
.RE
.sp
In the example above, messages are forwarded via UDP to the machine 192.168.0.1, the destination 
port defaults to 514. Due to the nature of UDP, you will probably lose some messages in transit.
If you expect high traffic volume, you can expect to lose a quite noticeable number of messages
(the higher the traffic, the more likely and severe is message loss).

.B If you would like to prevent message loss, use RELP:
.RS
*.* :omrelp:192.168.0.1:2514
.RE
.sp
Note that a port number was given as there is no standard port for relp.

Keep in mind that you need to load the correct input and output plugins (see "Modules" above).

Please note that rsyslogd offers a variety of options in regarding to remote
forwarding. For full details, please see the html documentation.

.SS List of users
Usually critical messages are also directed to ``root'' on that machine. You
can specify a list 
of users that shall get the message by simply writing ":omusrmsg:" followed
by the login name. You may specify more than one 
user by separating them with commas (','). If they're logged in they
get the message (for example: ":omusrmsg:root,user1,user2").

.SS Everyone logged on
Emergency messages often go to all users currently online to notify them that something strange 
is happening with the system. To specify this wall(1)-feature use an ":omusrmsg:*".

.SS Database table
This allows logging of the message to a database table.
By default, a MonitorWare-compatible schema is required for this to work. You can 
create that schema with the createDB.SQL file that came with the rsyslog package. You can also
use any other schema of your liking - you just need to define a proper template and assign this 
template to the action.

See the html documentation for further details on database logging.

.SS Discard
If the discard action is carried out, the received message is immediately discarded. Discard 
can be highly effective if you want to filter out some annoying messages that otherwise would 
fill your log files. To do that, place the discard actions early in your log files. 
This often plays well with property-based filters, giving you great freedom in specifying 
what you do not want.

Discard is just the single tilde character with no further parameters.
.sp
.B Example:
.RS
*.*   ~      # discards everything.
.RE


.SS Output channel
Binds an output channel definition (see there for details) to this action. Output channel actions 
must start with a $-sign, e.g. if you would like to bind your output channel definition "mychannel"
to the action, use "$mychannel". Output channels support template definitions like all all other 
actions.

.SS Shell execute
This executes a program in a subshell. The program is passed the template-generated message as the 
only command line parameter. Rsyslog waits until the program terminates and only then continues to run.

.B Example:
.RS
^program-to-execute;template
.RE

The program-to-execute can be any valid executable. It receives the template string as a single parameter 
(argv[1]).

.SH FILTER CONDITIONS
Rsyslog offers three different types "filter conditions":
.sp 0
   * "traditional" severity and facility based selectors
.sp 0
   * property-based filters
.sp 0
   * expression-based filters
.RE

.SS Selectors
.B Selectors are the traditional way of filtering syslog messages. 
They have been kept in rsyslog with their original syntax, because it is well-known, highly 
effective and also needed for compatibility with stock syslogd configuration files. If you just 
need to filter based on priority and facility, you should do this with selector lines. They are 
not second-class citizens in rsyslog and offer the best performance for this job.

.SS Property-Based Filters
Property-based filters are unique to rsyslogd. They allow to filter on any property, like HOSTNAME, 
syslogtag and msg. 

A property-based filter must start with a colon in column 0. This tells rsyslogd that it is the new 
filter type. The colon must be followed by the property name, a comma, the name of the compare 
operation to carry out, another comma and then the value to compare against. This value must be quoted. 
There can be spaces and tabs between the commas. Property names and compare operations are 
case-sensitive, so "msg" works, while "MSG" is an invalid property name. In brief, the syntax is as follows:
.sp
.RS
:property, [!]compare-operation, "value"
.RE

The following compare-operations are currently supported:
.sp
.RS
.B contains
.RS
Checks if the string provided in value is contained in the property
.RE
.sp
.B isequal
.RS
Compares the "value" string provided and the property contents. These two values must be exactly equal to match. 
.RE
.sp
.B startswith
.RS
Checks if the value is found exactly at the beginning of the property value
.RE
.sp
.B regex
.RS 
Compares the property against the provided regular expression.
.RE

.SS Expression-Based Filters
See the html documentation for this feature.


.SH TEMPLATES

Every output in rsyslog uses templates - this holds true for files, user 
messages and so on. Templates compatible with the stock syslogd 
formats are hardcoded into rsyslogd. If no template is specified, we use 
one of these hardcoded templates. Search for "template_" in syslogd.c and 
you will find the hardcoded ones.

A template consists of a template directive, a name, the actual template text 
and optional options. A sample is:

.RS
.B $template MyTemplateName,"\\\\7Text %property% some more text\\\\n",
.RE

The "$template" is the template directive. It tells rsyslog that this line 
contains a template. The backslash is an escape character. For example, \\7 rings the 
bell (this is an ASCII value), \\n is a new line. The set in rsyslog is a bit restricted 
currently.

All text in the template is used literally, except for things within percent 
signs. These are properties and allow you access to the contents of the syslog 
message. Properties are accessed via the property replacer and it can for example
pick a substring or do date-specific formatting. More on this is the PROPERTY REPLACER
section of this manpage.

To escape:
.sp 0
   % = \\%
.sp 0
   \\ = \\\\ --> '\\' is used to escape (as in C)
.sp 0
$template TraditionalFormat,"%timegenerated% %HOSTNAME% %syslogtag%%msg%\\n"

Properties can be accessed by the property replacer (see there for details).

.B Please note that templates can also by used to generate selector lines with dynamic file names.
For example, if you would like to split syslog messages from different hosts 
to different files (one per host), you can define the following template:

.RS
.B $template DynFile,"/var/log/system-%HOSTNAME%.log"
.RE
    
This template can then be used when defining an output selector line. It will 
result in something like "/var/log/system-localhost.log"

.SS Template options
The  part is optional. It carries options influencing the template as whole. 
See details below. Be sure NOT to mistake template options with property options - the 
later ones are processed by the property replacer and apply to a SINGLE property, only 
(and not the whole template).

Template options are case-insensitive. Currently defined are:

.RS
.TP 
sql
format the string suitable for a SQL statement in MySQL format. This will replace single 
quotes ("'") and the backslash character by their backslash-escaped counterpart 
("\'" and "\\") inside each field. Please note that in MySQL configuration, the NO_BACKSLASH_ESCAPES 
mode must be turned off for this format to work (this is the default).

.TP 
stdsql
format the string suitable for a SQL statement that is to be sent to a standards-compliant 
sql server. This will replace single quotes ("'") by two single quotes ("''") inside each field. 
You must use stdsql together with MySQL if in MySQL configuration the NO_BACKSLASH_ESCAPES 
is turned on.
.RE

Either the
.B sql
or 
.B stdsql 
option 
.B MUST 
be specified when a template is used for writing to a database, 
otherwise injection might occur. Please note that due to the unfortunate fact 
that several vendors have violated the sql standard and introduced their own 
escape methods, it is impossible to have a single option doing all the work.  
So you yourself must make sure you are using the right format.
.B If you choose the wrong one, you are still vulnerable to sql injection.

Please note that the database writer *checks* that the sql option is present 
in the template. If it is not present, the write database action is disabled. 
This is to guard you against accidental forgetting it and then becoming 
vulnerable to SQL injection. The sql option can also be useful with files - 
especially if you want to import them into a database on another machine for 
performance reasons. However, do NOT use it if you do not have a real need for 
it - among others, it takes some toll on the processing time. Not much, but on 
a really busy system you might notice it ;)

The default template for the write to database action has the sql option set. 

.SS Template examples
Please note that the samples are split across multiple lines. A template MUST 
NOT actually be split across multiple lines.

A template that resembles traditional syslogd file output:
.sp
.RS
$template TraditionalFormat,"%timegenerated% %HOSTNAME%
.sp 0
%syslogtag%%msg:::drop-last-lf%\\n"
.RE

A template that tells you a little more about the message:
.sp
.RS
$template precise,"%syslogpriority%,%syslogfacility%,%timegenerated%,%HOSTNAME%,
.sp 0
%syslogtag%,%msg%\\n"
.RE

A template for RFC 3164 format:
.sp
.RS
$template RFC3164fmt,"<%PRI%>%TIMESTAMP% %HOSTNAME% %syslogtag%%msg%"
.RE

A template for the format traditionally used for user messages:
.sp
.RS
$template usermsg," XXXX%syslogtag%%msg%\\n\\r"
.RE

And a template with the traditional wall-message format:
.sp
.RS
$template wallmsg,"\\r\\n\\7Message from syslogd@%HOSTNAME% at %timegenerated%"
.RE

.B A template that can be used for writing to a database (please note the SQL template option)
.sp
.RS
.ad l
$template MySQLInsert,"insert iut, message, receivedat values
('%iut%', '%msg:::UPPERCASE%', '%timegenerated:::date-mysql%')
into systemevents\\r\\n", SQL

NOTE 1: This template is embedded into core application under name 
.B StdDBFmt
, so you don't need to define it.
.sp
NOTE 2: You have to have MySQL module installed to use this template.
.ad
.RE

.SH OUTPUT CHANNELS

Output Channels are a new concept first introduced in rsyslog 0.9.0. As of this writing, 
it is most likely that they will be replaced by something different in the future.
So if you use them, be prepared to change you configuration file syntax when you upgrade 
to a later release.

Output channels are defined via an $outchannel directive. It's syntax is as follows:
.sp
.RS
.B $outchannel name,file-name,max-size,action-on-max-size
.RE

name is the name of the output channel (not the file), file-name is the file name to be 
written to, max-size the maximum allowed size and action-on-max-size a command to be issued 
when the max size is reached. This command always has exactly one parameter. The binary is 
that part of action-on-max-size before the first space, its parameter is everything behind 
that space.

Keep in mind that $outchannel just defines a channel with "name". It does not activate it. 
To do so, you must use a selector line (see below). That selector line includes the channel 
name plus ":omfile:$" in front of it. A sample might be:
.sp
.RS
*.* :omfile:$mychannel
.RE

.SH PROPERTY REPLACER
The property replacer is a core component in rsyslogd's output system. A syslog message has 
a number of well-defined properties (see below). Each of this properties can be accessed and 
manipulated by the property replacer. With it, it is easy to use only part of a property value 
or manipulate the value, e.g. by converting all characters to lower case.

.SS Accessing Properties
Syslog message properties are used inside templates. They are accessed by putting them between 
percent signs. Properties can be modified by the property replacer. The full syntax is as follows:
.sp
.RS
.B %propname:fromChar:toChar:options%
.RE

propname is the name of the property to access. 
.B It is case-sensitive.

.SS Available Properties

.TP
.B $MINUTE

.P
Properties starting with a $-sign are so-called system properties. These do NOT stem from the 
message but are rather internally-generated.

.SS Character Positions
FromChar and toChar are used to build substrings. They specify the offset within the string that 
should be copied. Offset counting starts at 1, so if you need to obtain the first 2 characters of 
the message text, you can use this syntax: "%msg:1:2%". If you do not wish to specify from and to, 
but you want to specify options, you still need to include the colons. For example, if you would 
like to convert the full message text to lower case, use "%msg:::lowercase%". If you would like to 
extract from a position until the end of the string, you can place a dollar-sign ("$") in toChar 
(e.g. %msg:10:$%, which will extract from position 10 to the end of the string).

There is also support for 
.B regular expressions.
To use them, you need to place a "R" into FromChar. 
This tells rsyslog that a regular expression instead of position-based extraction is desired. The 
actual regular expression 
.B must 
then be provided in toChar. The regular expression must be followed 
by the string "--end". It denotes the end of the regular expression and will not become part of it. 
If you are using regular expressions, the property replacer will return the part of the property text 
that matches the regular expression. An example for a property replacer sequence with a regular 
expression is: "%msg:R:.*Sev:. \\(.*\\) \\[.*--end%"

Also, extraction can be done based on so-called "fields". To do so, place a "F" into FromChar. A field 
in its current definition is anything that is delimited by a delimiter character. The delimiter by 
default is TAB (US-ASCII value 9). However, if can be changed to any other US-ASCII character by 
specifying a comma and the decimal US-ASCII value of the delimiter immediately after the "F". For example, 
to use comma (",") as a delimiter, use this field specifier: "F,44".  If your syslog data is delimited, 
this is a quicker way to extract than via regular expressions (actually, a *much* quicker way). Field 
counting starts at 1. Field zero is accepted, but will always lead to a "field not found" error. The same 
happens if a field number higher than the number of fields in the property is requested. The field number 
must be placed in the "ToChar" parameter. An example where the 3rd field (delimited by TAB) from the msg 
property is extracted is as follows: "%msg:F:3%". The same example with semicolon as delimiter is 
"%msg:F,59:3%".

Please note that the special characters "F" and "R" are case-sensitive. Only upper case works, lower case 
will return an error. There are no white spaces permitted inside the sequence (that will lead to error 
messages and will NOT provide the intended result).

.SS Property Options
Property options are case-insensitive. Currently, the following options are defined:
.TP
uppercase
convert property to lowercase only
.TP
lowercase
convert property text to uppercase only
.TP
drop-last-lf
The last LF in the message (if any), is dropped. Especially useful for PIX.
.TP
date-mysql
format as mysql date
.TP
date-rfc3164
format as RFC 3164 date
.TP
date-rfc3339
format as RFC 3339 date
.TP
escape-cc
replace control characters (ASCII value 127 and values less then 32) with an escape sequence. The sequence is "#" where charval is the 3-digit decimal value of the control character. For example, a tabulator would be replaced by "#009".
.TP
space-cc
replace control characters by spaces
.TP
drop-cc
drop control characters - the resulting string will neither contain control characters, escape sequences nor any other replacement character like space.

.SH QUEUED OPERATIONS
Rsyslogd supports queued operations to handle offline outputs
(like remote syslogd's or database servers being down). When running in
queued mode, rsyslogd buffers messages to memory and optionally to disk
(on an as-needed basis). Queues survive rsyslogd restarts.

It is highly suggested to use remote forwarding and database writing
in queued mode, only.

To learn more about queued operations, see the html documentation.

 *
 * This is an abstracted module. As Linux and BSD kernel log is conceptually the
 * same, we do not do different input plugins for them but use
 * imklog in both cases, just with different "backend drivers" for
 * the different platforms. This also enables a rsyslog.conf to
 * be used on multiple platforms without the need to take care of
 * what the kernel log is coming from.
 *
 * See platform-specific files (e.g. linux.c, bsd.c) in the plugin's
 * working directory. For other systems with similar kernel logging
 * functionality, no new input plugin shall be written but rather a
 * driver be developed for imklog. Please note that imklog itself is
 * mostly concerned with handling the interface. Any real action happens
 * in the drivers, as things may be pretty different on different
 * platforms.
 *
 * Please note that this file replaces the klogd daemon that was
 * also present in pre-v3 versions of rsyslog.
 *
 * To test under Linux:
 * echo test1 > /dev/kmsg

 * This input module is used to gather local log data under Solaris. This
 * includes messages from local applications AS WELL AS the kernel log.
 * I first considered to make all of this available via imklog, but that
 * did not lock appropriately on second thought. So I created this module
 * that does anything for local message recption.
 *
 * This module is not meant to be used on plaforms other than Solaris. As
 * such, trying to compile it elswhere will probably fail with all sorts
 * of errors.
 * 
 * Some notes on the Solaris syslog mechanism:
 * Both system (kernel) and application log messages are provided via
 * a single message stream.
 *
 * Solaris checks if the syslogd is running. If so, syslog() emits messages
 * to the log socket, only. Otherwise, it emits messages to the console.
 * It is possible to gather these console messages as well. However, then
 * we clutter the console.
 * Solaris does this "syslogd alive check" in a somewhat unexpected way
 * (at least unexpected for me): it uses the so-called "door" mechanism, a
 * fast RPC facility. I first thought that the door API was used to submit
 * the actual syslog messages. But this is not the case. Instead, a door
 * call is done, and the server process inside rsyslog simply does NOTHING
 * but return. All that Solaris sylsogd() is interested in is if the door
 * server (we) responds and thus can be considered alive. The actual message
 * is then submitted via the usual stream. I have to admit I do not 
 * understand why the message itself is not passed via this high-performance
 * API. But anyhow, that's nothing I can change, so the most important thing
 * is to note how Solaris does this thing ;)
 * The syslog() library call checks syslogd state for *each* call (what a 
 * waste of time...) and decides each time if the message should go to the
 * console or not.  According to OpenSolaris sources, it looks like there is
 * message loss potential when the door file is created before all data has
 * been pulled from the stream. While I have to admit that I do not fully
 * understand that problem, I will follow the original code advise and do
 * one complete pull cycle on the log socket (until it has no further data
 * available) and only thereafter create the door file and start the "regular"
 * pull cycle. As of my understanding, there is a minimal race between the
 * point where the intial pull cycle has ended and the door file is created,
 * but that race is also present in OpenSolaris syslogd code, so it should
 * not matter that much (plus, I do not know how to avoid it...)

 *
 * This is an implementation of a mail sending output module. So far, we
 * only support direct SMTP, that is talking to a SMTP server. In the long
 * term, support for using sendmail should also be implemented. Please note
 * that the SMTP protocol implementation is a very bare one. We support 
 * RFC821/822 messages, without any authentication and any other nice
 * features (no MIME, no nothing). It is assumed that proper firewalling
 * and/or STMP server configuration is used together with this module.
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!

 * This is a very special output module. It permits to pass a message object
 * to another rule set. While this is a very simple action, it enables very
 * complex configurations, e.g. it supports high-speed "and" conditions, sending
 * data to the same file in a non-racy way, include functionality as well as
 * some high-performance optimizations (in case the rule sets have the necessary
 * queue definitions). So while this code is small, it is pretty important.
 *
 * NOTE: read comments in module-template.h for details on the calling interface!

 *
 * This is a udp-based output module that support spoofing.
 *
 * This file builds on UDP spoofing code contributed by 
 * David Lang . I then created a "real" rsyslog module
 * out of that code and omfwd. I decided to make it a separate module because
 * omfwd already mixes up too many things (TCP & UDP & a different modes,
 * this has historic reasons), it would not be a good idea to also add
 * spoofing to it. And, looking at the requirements, there is little in 
 * common between omfwd and this module.
 *
 * Note: I have briefly checked libnet source code and I somewhat have the feeling
 * that under some circumstances we may get into trouble with the lib. For
 * example, it registers an atexit() handler, which should not play nicely
 * with our dynamically loaded modules. Anyhow, I refrain from looking deeper
 * at libnet code, especially as testing does not show any real issues. If some
 * occur, it may be easier to modify libnet for dynamic load environments than
 * using a work-around (as a side not, libnet looks somewhat unmaintained, the CVS
 * I can see on sourceforge dates has no updates done less than 7 years ago).
 * On the other hand, it looks like libnet is thread safe (at least is appropriately
 * compiled, which I hope the standard packages are). So I do not guard calls to
 * it with my own mutex calls.

 *
 * This module is a testing aid. It is not meant to be used in production. I have
 * initially written it to introduce delays of custom length to action processing.
 * This is needed for development of new message queueing methods. However, I think
 * there are other uses for this module. For example, I can envision that it is a good
 * thing to have an output module that requests a retry on every "n"th invocation
 * and such things. I implement only what I need. But should further testing needs
 * arise, it makes much sense to add them here.
 *
 * This module will become part of the CVS and the rsyslog project because I think
 * it is a generally useful debugging, testing and development aid for everyone
 * involved with rsyslog.
 *
 * CURRENT SUPPORTED COMMANDS:
 *
 * :omtesting:sleep  
 *
 * Must be specified exactly as above. Keep in mind milliseconds are a millionth
 * of a second!
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!

 * in cases where journal serves as the whole system log database.
 * Note that we may get into a loop if journald re-injects messages
 * into the syslog stream and we read that via imuxsock. Thus there
 * is an option in imuxsock to ignore messages from ourselves 
 * (actually from our pid). So there are some module-interdependencies.

 * The rfc3195 input module.
 *
 * Please note that this file replaces the rfc3195d daemon that was
 * also present in pre-v3 versions of rsyslog.
 *
 * WARNING: due to no demand at all for RFC3195, we have converted rfc3195d
 * to this input module, but we have NOT conducted any testing. Also,
 * the module does not yet properly handle the recovery case. If someone
 * intends to put this module into production, good testing should be
 * made and it also is a good idea to notify me that you intend to use
 * it in production. In this case, I'll probably give the module another
 * cleanup. I don't do this now because so far it looks just like a big
 * waste of time. -- rgerhards, 2008-04-16

 * then a callback (doOpenLstnSocks) into imtcp happens, which in turn calls
 * into tcpsrv.create_tcp_socket(),
 * which calls into netstrm.LstnInit(), which receives a pointer to netstrms obj
 * which calls into the driver function LstnInit (again, netstrms obj passed)
 * which finally calls back into netstrms obj's get functions to obtain the auth

 * This is an experimental plain tcp input module which follows the
 * multiple thread paradigm.
 *
 * WARNING
 * This module is unfinished. It seems to work, but there also seems to be a problem
 * if it is under large stress (e.g. tcpflood with more than 500 to 1000 concurrent
 * connections). I quickly put together this module after I worked on a larger paper
 * and read [1], which claims that using massively threaded applications is
 * preferrable to an event driven approach. So I put this to test, especially as
 * that would also lead to a much simpler programming paradigm. Unfortuantely, the
 * performance results are devastive: while there is a very slight speedup with 
 * a low connection number (close to the number of cores on the system), there
 * is a dramatic negative speedup if running with many threads. Even at only 50
 * connections, rsyslog is dramatically slower (80 seconds for the same workload
 * which was processed in 60 seconds with traditional imtcp or when running on
 * a single connection). At 1,000 connections, the run was *extremely* slow. So
 * this is definitely a dead-end. To be honest, Behren, condit and Brewer claim
 * that the problem lies in the current implementation of thread libraries.
 * As one cure, they propose user-level threads. However, as far as I could
 * find out, User-Level threads seem not to be much faster under Linux than
 * Kernel-Level threads (which I used in my approach). 
 *
 * Even more convincing is, from the rsyslog PoV, that there are clear reasons
 * why the highly threaded input must be slower:
 * o batch sizes are smaller, leading to much more overhead
 * o many more context switches are needed to switch between the various
 *   i/o handlers
 * o more OS API calls are required because in this model we get more
 *   frequent wakeups on new incoming data, so we have less data available
 *   to read at each instant
 * o more lock contention because many more threads compete on the
 *   main queue mutex
 *
 * All in all, this means that the approach is not the right one, at least
 * not for rsyslog (it may work better if the input can be processed
 * totally independent, but I have note evaluated this). So I will look into
 * an enhanced event-based model with a small set of input workers pulling
 * off data (I assume this is useful for e.g. TLS, as TLS transport is much
 * more computebound than other inputs, and this computation becomes a
 * limiting factor for the overall processing speed under some
 * circumstances - see [2]).
 *
 * For obvious reasons, I will not try to finish imttcp. However, I have
 * decided to leave it included in the source tree, so that
 * a) someone else can build on it, if he sees value in that
 * b) I may use it for some other tests in the future
 *
 * But if you intend to actually use this module unmodified, be prepared
 * for problems.
 *
 * [1] R. Von Behren, J. Condit, and E. Brewer. Why events are a bad idea
 *     (for high-concurrency servers). In Proceedings of the 9th conference on Hot
 *     Topics in Operating Systems-Volume 9, page 4. USENIX Association, 2003.

tested in ubuntu 10.04 and ubuntu 10.10

configuration:

in your /etc/rsyslog.conf, together with other modules:
$ModLoad ommongodb # provides mongodb support
*.*     action(type="ommongodb" db="..." collection="..." template="...")

Note: if no template is specified, a default schema will be used. That schema
contains proper data types. However, if a template is specified, only strings
are supported. This is a restriction of the rsyslog v6 core engine. This 
changed in v7.

If templates are used, it is suggested to use list-based templates. Constants
can ONLY be inserted with list-based templates, as only these provide the
capability to specify a field name (outname parameter).

 * This is a native implementation of plain tcp. It is intentionally
 * duplicate work (imtcp). The intent is to gain very fast and simple
 * native ptcp support, utilizing the best interfaces Linux (no cross-
 * platform intended!) has to offer.
 *
 * Note that in this module we try out some new naming conventions,
 * so it may look a bit "different" from the other modules. We are
 * investigating if removing prefixes can help make code more readable.

Building this plugin:
Requires libzmq and libczmq. First, download the tarballs of both libzmq
and its supporting libczmq from http://download.zeromq.org. As of this
writing (04/23/2013), the most recent versions of libzmq and czmq are
3.2.2 and 1.3.2 respectively. Configure, build, and then install both libs.

Imzmq3 allows you to push data into rsyslog from a zeromq socket.  The example
below binds a SUB socket to port 7172, and then any messages with the topic
"foo" will be pushed into rsyslog.

Please note:
This plugin only supports the newer (v7) config format.  Legacy config support
was removed.

Example Rsyslog.conf snippet:

module(load="imzmq3" ioThreads="1")
input(type="imzmq3" action="CONNECT" socktype="SUB" description="tcp://*:7172" subscribe="foo,bar")

-------------------------------------------------------------------------------
Note you can specify multiple subscriptions with a comma-delimited list, with 
no spaces between values.  

The only global parameter for this plugin is ioThreads, which is optional and
probably best left to the zmq default unless you know exactly what you are
doing.

The instance-level parameters are:

Required
description
subscribe (required if the sockType is SUB)

Optional
sockType (defaults to SUB)
action   (defaults to BIND
sndHWM   
rcvHWM
identity
sndBuf
rcvBuf
linger
backlog
sndTimeout
rcvTimeout
maxMsgSize
rate
recoveryIVL
multicastHops
reconnectIVL
reconnectIVLMax
ipv4Only
affinity

These all correspond to zmq optional settings.  Except where noted, the defaults
are the zmq defaults if not set.  See http://api.zeromq.org/3-2:zmq-setsockopt
for info on these.

 * This is a message modification module supporting Linux audit format
 * in various settings. The module tries to identify the provided
 * message as being a Linux audit record and, if so, converts it into
 * cee-enhanced syslog format.
 *
 * NOTE WELL:
 * Right now, we do not do any trust checks. So it is possible that a
 * malicous user emits something that looks like an audit record and
 * tries to fool the system with that. Solving this trust issue is NOT
 * an easy thing to do. This will be worked on, as the lumberjack effort
 * continues. Please consider the module in its current state as a proof
 * of concept.

========================
It's quite easy to get 400, if you put a wrong mapping to your
index. That would be easy to reproduce in "normal" omelasticsearch usage
conditions, by only altering the ES configuration:

1. Make your index first. Let's call it "testindex":
$ curl -XPUT localhost:9200/testindex/

2. Put your mapping for a search type called "mytype", where you specify
that date property should be an integer:
$ curl -XPUT localhost:9200/testindex/mytype/_mapping -d '{"mytype":{"properties": {"timegenerated":{"type":"integer"}}}}'

3. Now try to insert something where date is not an integer:
$ curl -XPOST localhost:9200/testindex/mytype/ -d '{"timegenerated":"bla"}'
{"error":"MapperParsingException[Failed to parse [date]]; nested: NumberFormatException[For input string: \"bla\"]; ","status":400}

    This is an output module feeding directly to an Oracle
    database. It uses Oracle Call Interface, a propietary module
    provided by Oracle.

    Selector lines to be used are of this form:

    :omoracle:;TemplateName

    The module gets its configuration via rsyslog $... directives,
    namely:

    $OmoracleDBUser: user name to log in on the database.

    $OmoracleDBPassword: password to log in on the database.

    $OmoracleDB: connection string (an Oracle easy connect or a db
    name as specified by tnsnames.ora)

    $OmoracleBatchSize: Number of elements to send to the DB on each
    transaction.

    $OmoracleBatchItemSize: Number of characters each property may
    have. Make it as big as the longest value you expect for *any*
    property in the sentence. For instance, if you expect 5 arguments
    to the statement, 4 have 10 bytes and the 5th may be up to 3KB,
    then specify $OmoracleBatchItemSize 3072. Please, remember to
    leave space to the trailing \0!!

    $OmoracleStatementTemplate: Name of the template containing the
    statement to be prepared and executed in batches. Please note that
    Oracle's prepared statements have their placeholders as
    ':identifier', and this module uses the colon to guess how many
    placeholders there will be.

    All these directives are mandatory. The dbstring can be an Oracle
    easystring or a DB name, as present in the tnsnames.ora file.

    The form of the template is just a list of strings you want
    inserted to the DB, for instance:

    $template TestStmt,"%hostname%%msg%"

    Will provide the arguments to a statement like

    $OmoracleStatement \
        insert into foo(hostname,message)values(:host,:message)

    Also note that identifiers to placeholders are arbitrary. You need
    to define the properties on the template in the correct order you
    want them passed to the statement!

    your choice, any later version. Exceptionally (perhaps), you are

Building this plugin:
Requires libzmq and libczmq. First, download the tarballs of both libzmq
and its supporting libczmq from http://download.zeromq.org. As of this
writing (04/23/2013), the most recent versions of libzmq and czmq are
3.2.2 and 1.3.2 respectively. Configure, build, and then install both libs.

Omzmq3 allows you to push data out of rsyslog from a zeromq socket.  The example
below binds a PUB socket to port 7171, and any message fitting the criteria will
be output to the zmq socket.

Example Rsyslog.conf snippet (NOTE: v6 format):
-------------------------------------------------------------------------------
if $msg then {
    action(type="omzmq3", sockType="PUB", action="BIND", 
           description="tcp://*:7172)
}

 *
 * this detects logs sent by Cisco devices that mangle their syslog output when you tell them to log by name by adding ' :' between the name and the %XXX-X-XXXXXXX: tag
 * 
 * instead of actually parsing the message, this modifies the message and then falls through to allow a later parser to handle the now modified message
 *
 * created 2010-12-13 by David Lang based on pmlastmsg

 * This is a custom developed plugin to process bind information into
 * a specific SQL statement. While the actual processing may be too specific
 * to be of general use, this module serves as a template on how this type
 * of processing can be done.
 *
 * Format generated:
 * "%TIMESTAMP:::date-rfc3339% %HOSTNAME% %syslogtag%%msg:::sp-if-no-1st-sp%%msg:::drop-last-lf%\n"
 * Note that this is the same as smtradfile.c, except that we do have a RFC3339 timestamp. However,
 * we have copied over the code from there, it is too simple to go through all the hassle
 * of having a single code base.
 *
 * NOTE: read comments in module-template.h to understand how this file
 *       works!

                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.

  Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
License. Each licensee is addressed as "you". "Licensees" and
"recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy. The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
on the Program.

  To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.

  The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.

  The Corresponding Source for a work in source code form is that
same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.

  You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.

  Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.

  When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7. This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy. This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged. This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source. This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge. You need not require recipients to copy the
    Corresponding Source along with the object code. If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source. Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

  A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.

  A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.

  If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).

  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.

  Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.

  When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:

    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or

    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or

    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or

    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or

    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.

  All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.

  If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.

  8. Termination.

  You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).

  However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.

  Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.

  Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.

  An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.

  You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".

  A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.

  Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.

  In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.

  If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.

  If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.

  A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.

  Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

  Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.

  Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    
    Copyright (C)  

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program. If not, see .

Also add information on how to contact you by electronic and paper mail.

  If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:

     Copyright (C)  
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".

  You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.

  The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
.

tested in Centos 6.2 and Archlinux

BUILDING THIS PLUGIN
Requires the hiredis C client library: https://github.com/redis/hiredis/

in your /etc/rsyslog.conf, together with other modules:

Brian Knox 

---------------------------------------------------------------------------------------------
module(load="omhiredis")

template(name="simple_count" type="string" string="HINCRBY progcount %programname% 1")

action(name="simple_count_redis" type="omhiredis" queue.type="FixedArray" queue.size="10000" queue.dequeuebatchsize="100" template="simple_count")
---------------------------------------------------------------------------------------------

Note: dequeuebatchsize now sets the pipeline size for hiredis, allowing pipelining commands.
Note: this plugin will NOT handle full rsyslog messages properly yet. spaces in a property will
        cause the redis command to be constructed improperly.  a fix for this is in the works!

 *
 * We go through all files and remember if at least one had data. If so, we do
 * another run (until no data was present in any file). Then we sleep for
 * PollInterval seconds and restart the whole process. This ensures that as
 * long as there is some data present, it will be processed at the fastest

 * single file, the algorithm is slightly modified. In that case, the sleep
 * hapens immediately. The idea here is that if we have just one file, we
 * returned from the file processer because that file had no additional data.
 * So even if we found some lines, it is highly unlikely to find a new one
 * just now. Trying it would result in a performance-costly additional try
 * which in the very, very vast majority of cases will never find any new

 *
 * this detects logs sent by Snare and cleans them up so that they can be processed by the normal parser
 *
 * there are two variations of this, if the client is set to 'syslog' mode it sends
 *
 * timestamphostnametagotherstuff
 *
 * if the client is not set to syslog it sends
 *
 * hostnametagotherstuff
 *
 * ToDo, take advantage of items in the message itself to set more friendly information
 * where the normal parser will find it by re-writing more of the message
 *
 * Intereting information includes:
 *
 * in the case of windows snare messages:
 *   the system hostname is field 12
 *   the severity is field 3 (criticality ranging form 0 to 4)
 *   the source of the log is field 4 and may be able to be mapped to facility
 *

                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.

  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.

  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.  You must make sure that they, too, receive
or can get the source code.  And you must show them these terms so they
know their rights.

  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.

  For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software.  For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.

  Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so.  This is fundamentally incompatible with the aim of
protecting users' freedom to change the software.  The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the practice for those
products.  If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.

  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.

  The precise terms and conditions for copying, distribution and
modification follow.

                       TERMS AND CONDITIONS

  0. Definitions.

  "This License" refers to version 3 of the GNU General Public License.

  "Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.

  "The Program" refers to any copyrightable work licensed under this
License.  Each licensee is addressed as "you".  "Licensees" and
"recipients" may be individuals or organizations.

  To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy.  The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.

  A "covered work" means either the unmodified Program or a work based
on the Program.

  To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy.  Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

  To "convey" a work means any kind of propagation that enables other
parties to make or receive copies.  Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.

  An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License.  If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.

  1. Source Code.

  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.

  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form.  A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.

  The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.

  The Corresponding Source for a work in source code form is that
same work.

  2. Basic Permissions.

  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the unmodified Program.  The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.  This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.

  You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force.  You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright.  Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.

  Conveying under any other circumstances is permitted solely under
the conditions stated below.  Sublicensing is not allowed; section 10
makes it unnecessary.

  3. Protecting Users' Legal Rights From Anti-Circumvention Law.

  No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.

  When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.

  4. Conveying Verbatim Copies.

  You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.

  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.

  5. Conveying Modified Source Versions.

  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:

    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.

    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".

    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.

    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.

  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.

  6. Conveying Non-Source Forms.

  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:

    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.

    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.

    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.

    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.

    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.

  A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.

  A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling.  In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.

  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source.  The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.

  If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information.  But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).

  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.

  Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.

  7. Additional Terms.

  "Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.

  When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  (Additional permissions may be written to require their own
removal in certain cases when you modify the work.)  You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.

  Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:

    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or

    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or

    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or

    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or

    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or

    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.

  All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10.  If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term.  If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.

  If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.

  Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.

  8. Termination.

  You may not propagate or modify a covered work except as expressly
provided under this License.  Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).

  However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.

  Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.

  Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.

  9. Acceptance Not Required for Having Copies.

  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
nothing other than this License grants you permission to propagate or
modify any covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.

  10. Automatic Licensing of Downstream Recipients.

  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.  You are not responsible
for enforcing compliance by third parties with this License.

  An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.  If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.

  You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.

  11. Patents.

  A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based.  The
work thus licensed is called the contributor's "contributor version".

  A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version.  For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.

  Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.

  In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement).  To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.

  If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients.  "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.

  If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.

  A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License.  You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.

  Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.

  12. No Surrender of Others' Freedom.

  If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all.  For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.

  13. Use with the GNU Affero General Public License.

  Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work.  The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.

  14. Revised Versions of this License.

  The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

  Each version is given a distinguishing version number.  If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.  If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.

  If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.

  Later license versions may give you additional or different
permissions.  However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.

  15. Disclaimer of Warranty.

  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

  16. Limitation of Liability.

  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.

  17. Interpretation of Sections 15 and 16.

  If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.

                     END OF TERMS AND CONDITIONS

            How to Apply These Terms to Your New Programs

  If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

  To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

    
    Copyright (C)   

    This program is free software: you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation, either version 3 of the License, or
    (at your option) any later version.

    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

    You should have received a copy of the GNU General Public License
    along with this program.  If not, see .

Also add information on how to contact you by electronic and paper mail.

  If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:

      Copyright (C)   
    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".

  You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
.

  The GNU General Public License does not permit incorporating your program
into proprietary programs.  If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.  But first, please read
.

# utilized by any test that just needs two instances with different
# config files, where messages are injected in instance TWO and 
# (with whatever rsyslog mechanism) being relayed over to instance ONE,
# where they are written to the log file. After the run, the completeness
# of that log file is checked.
# The code is almost the same, but the config files differ (probably greatly)
# for different test cases. As such, this driver needs to be called with the
# config file name ($2). From that name, the sender and receiver config file
# names are automatically generated. 
# So: $1 config file name, $2 number of messages
#
# A note on TLS testing: the current testsuite (in git!) already contains
# TLS test cases. However, getting these test cases correct is not simple.
# That's not a problem with the code itself, but rater a problem with
# synchronization in the test environment. So I have deciced to keep the
# TLS tests in, but not yet actually utilize them. This is most probably
# left as an excercise for future (devel) releases. -- rgerhards, 2009-11-11

# caused a deadlock during processing (when the a stream was purged from the
# dynafile cache).
# We added this as a standard test in the hopes that iw will help
# detect such things in the future.
#
# The problem that originally caused this test to fail was:
# We write to files asynchronously (with the async writer thread). There is
# no signaling done when the file stream is closed. That can lead to the writer
# process hanging in memory, that in turn leads to the main thread waiting on a
# condition that never occurs (because it would need to be signalled by the
# async writer). Even worse, in that case, the async writer was signalled invalid
# in such a way that when it received a wakeup, it thought it shall not terminate,
# but received a spurios wakeup due to timeout and no data to write. In that case
# it (correctly) concluded that it would not need to timeout until a new buffer write
# was done (in which case it would receive a wakeup). As such, it went into an eternal
# wait. However, the invalid signaling did not take into account that it did not
# signal the async writer to shut down. So the main thread went into a condition
# wait - and thus we had a deadlock. That situation occured only under very specific
# cirumstances. As far as the analysis goes, the following need to happen:
# 1. buffers on that file are being flushed
# 2. no new data arrives
# 3. the inactivity timeout has not yet expired
# 4. *then* (and only then) the stream is closed or destructed
# In that, 1 to 4 are prequisites for the deadlock which will happen in 4. However,
# for it to happen, we also need the right "timing". There is a race between the
# main thread and the async writer thread. The deadlock will only happen under
# the "right" circumstances, which basically means it will not happen always.
# In order to create this case as reliable as possible, I have used
# the "$OMFileFlushOnTXEnd on" directive
# inside my test case. It makes sure that #1 above happens. The test uses a dynafile
# cache size of 4, and the load generator generates data for 5 different dynafiles.
# So over time, we will hit a spot where 4 dynafiles are open and the 5th file name
# is generated. As such, one file needs to be discarded. Thanks to FlushOnTXEnd, we
# now likely have #2 in place and thanks to the load pattern generated, we most
# probably have #3 in place. During the dynafile cache displacement of the oldest
# entry, #4 is generated. At this point, we have the deadlock we are testing for.
# Note that this deadlock does not necessarily lead to a total lockup of rsyslogd.
# Parts of it continue to operate. But in our test setup, this means data is
# received and placed into the main queue. Once it's high water mark is hit, data 
# is still being enqueued, but at a slow rate. So if one is patient enough, the load
# generator will be able to finish. However, rsyslogd will never process the data
# it received because it is locked in the deadlock caused by #4 above.
# Note that "$OMFileFlushOnTXEnd on" is not causing this behaviour. We just use it
# to (quite) reliably cause the failure condition. The failure described above
# (in version 4.6.1) was also present when the setting was set to "off", but its
# occurence was very much less probable - because the perquisites are then much
# harder to hit. without it, the test may need to run for several hours before
# we hit all failure conditions.

# real-world scenario, the /dev/xconsole pipe. Some versions of rsyslog
# were known to hang or loop on this pipe, thus we added this scenario
# as a permanent testcase. For some details, please see bug tracker
# http://bugzilla.adiscon.com/show_bug.cgi?id=186
#
# IMPORTANT: we do NOT check any result message set. The whole point in
# this test is to verify that we do NOT run into an eternal loop. As such,
# the test is "PASS", if rsyslogd terminates. If it does not terminate, we
# obviously do not cause "FAIL", but processing will hang, which should be
# a good-enough indication of failure.

 * other things).
 *
 * The name of the test suite must be given as argv[1]. In this config,
 * rsyslogd is loaded with config ./testsuites/.conf and then
 * test cases ./testsuites/ *. are executed on it. This test driver is
 * suitable for testing cases where a message sent (via UDP) results in
 * exactly one response. It can not be used in cases where no response
 * is expected (that would result in a hang of the test driver).
 * Note: each test suite can contain many tests, but they all need to work
 * with the same rsyslog configuration.
 *
 * Part of the testbench for rsyslog.

evolving. New tests are always welcome. So far, most tests check
out the functionality of a single module. More complex tests are
welcome.

For a simple sample, see rtinit.c, which does a simple
init/deinit check of the runtime system.

 *      the TCP receiver.
 * -F	USASCII value for frame delimiter (in octet-stuffing mode), default LF
 * -R	number of times the test shall be run (very useful for gathering performance
 *      data and other repetitive things). Default: 1
 * -S   number of seconds to sleep between different runs (-R) Default: 30
 * -X   generate sTats data records. Default: off
 * -e   encode output in CSV (not yet everywhere supported)
 *      for performance data:
 *      each inidividual line has the runtime of one test
 *      the last line has 0 in field 1, followed by numberRuns,TotalRuntime,
 *      Average,min,max
 * -T   transport to use. Currently supported: "udp", "tcp" (default)
 *      Note: UDP supports a single target port, only
 * -W	wait time between sending batches of messages, in microseconds (Default: 0)
 * -b   number of messages within a batch (default: 100,000,000 millions)
 * -Y	use multiple threads, one per connection (which means 1 if one only connection
 *  	is configured!)
 * -z	private key file for TLS mode
 * -Z	cert (public key) file for TLS mode
 * -L	loglevel to use for GnuTLS troubleshooting (0-off to 10-all, 0 default)

# very rough support for compiling the java components of rsyslog
# Some usage notes: you need to use the Sun JDK compiler (jdk-devel)
# with this. At least it didn't work for me with the eclipse compiler.
# There is no real installation support. If you intend to run a program,
# change to the ./java subdirectory and issue
# java -cp . 
# e.g.: java -cp . com.rsyslog.gui.diaggui.DiagGUI
# or any equivalent command.
#
# I am very glad to hear suggestions about how to improve this part
# of the build system. -- rgerhards, 2009-08-27

                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. 
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.


  This version of the GNU Lesser General Public License incorporates
the terms and conditions of version 3 of the GNU General Public
License, supplemented by the additional permissions listed below.

  0. Additional Definitions. 

  As used herein, "this License" refers to version 3 of the GNU Lesser
General Public License, and the "GNU GPL" refers to version 3 of the GNU
General Public License.

  "The Library" refers to a covered work governed by this License,
other than an Application or a Combined Work as defined below.

  An "Application" is any work that makes use of an interface provided
by the Library, but which is not otherwise based on the Library.
Defining a subclass of a class defined by the Library is deemed a mode
of using an interface provided by the Library.

  A "Combined Work" is a work produced by combining or linking an
Application with the Library.  The particular version of the Library
with which the Combined Work was made is also called the "Linked
Version".

  The "Minimal Corresponding Source" for a Combined Work means the
Corresponding Source for the Combined Work, excluding any source code
for portions of the Combined Work that, considered in isolation, are
based on the Application, and not on the Linked Version.

  The "Corresponding Application Code" for a Combined Work means the
object code and/or source code for the Application, including any data
and utility programs needed for reproducing the Combined Work from the
Application, but excluding the System Libraries of the Combined Work.

  1. Exception to Section 3 of the GNU GPL.

  You may convey a covered work under sections 3 and 4 of this License
without being bound by section 3 of the GNU GPL.

  2. Conveying Modified Versions.

  If you modify a copy of the Library, and, in your modifications, a
facility refers to a function or data to be supplied by an Application
that uses the facility (other than as an argument passed when the
facility is invoked), then you may convey a copy of the modified
version:

   a) under this License, provided that you make a good faith effort to
   ensure that, in the event an Application does not supply the
   function or data, the facility still operates, and performs
   whatever part of its purpose remains meaningful, or

   b) under the GNU GPL, with none of the additional permissions of
   this License applicable to that copy.

  3. Object Code Incorporating Material from Library Header Files.

  The object code form of an Application may incorporate material from
a header file that is part of the Library.  You may convey such object
code under terms of your choice, provided that, if the incorporated
material is not limited to numerical parameters, data structure
layouts and accessors, or small macros, inline functions and templates
(ten or fewer lines in length), you do both of the following:

   a) Give prominent notice with each copy of the object code that the
   Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the object code with a copy of the GNU GPL and this license
   document.

  4. Combined Works.

  You may convey a Combined Work under terms of your choice that,
taken together, effectively do not restrict modification of the
portions of the Library contained in the Combined Work and reverse
engineering for debugging such modifications, if you also do each of
the following:

   a) Give prominent notice with each copy of the Combined Work that
   the Library is used in it and that the Library and its use are
   covered by this License.

   b) Accompany the Combined Work with a copy of the GNU GPL and this license
   document.

   c) For a Combined Work that displays copyright notices during
   execution, include the copyright notice for the Library among
   these notices, as well as a reference directing the user to the
   copies of the GNU GPL and this license document.

   d) Do one of the following:

       0) Convey the Minimal Corresponding Source under the terms of this
       License, and the Corresponding Application Code in a form
       suitable for, and under terms that permit, the user to
       recombine or relink the Application with a modified version of
       the Linked Version to produce a modified Combined Work, in the
       manner specified by section 6 of the GNU GPL for conveying
       Corresponding Source.

       1) Use a suitable shared library mechanism for linking with the
       Library.  A suitable mechanism is one that (a) uses at run time
       a copy of the Library already present on the user's computer
       system, and (b) will operate properly with a modified version
       of the Library that is interface-compatible with the Linked
       Version. 

   e) Provide Installation Information, but only if you would otherwise
   be required to provide such information under section 6 of the
   GNU GPL, and only to the extent that such information is
   necessary to install and execute a modified version of the
   Combined Work produced by recombining or relinking the
   Application with a modified version of the Linked Version. (If
   you use option 4d0, the Installation Information must accompany
   the Minimal Corresponding Source and Corresponding Application
   Code. If you use option 4d1, you must provide the Installation
   Information in the manner specified by section 6 of the GNU GPL
   for conveying Corresponding Source.)

  5. Combined Libraries.

  You may place library facilities that are a work based on the
Library side by side in a single library together with other library
facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your
choice, if you do both of the following:

   a) Accompany the combined library with a copy of the same work based
   on the Library, uncombined with any other library facilities,
   conveyed under the terms of this License.

   b) Give prominent notice with the combined library that part of it
   is a work based on the Library, and explaining where to find the
   accompanying uncombined form of the same work.

  6. Revised Versions of the GNU Lesser General Public License.

  The Free Software Foundation may publish revised and/or new versions
of the GNU Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may
differ in detail to address new problems or concerns.

  Each version is given a distinguishing version number. If the
Library as you received it specifies that a certain numbered version
of the GNU Lesser General Public License "or any later version"
applies to it, you have the option of following the terms and
conditions either of that published version or of any later version
published by the Free Software Foundation. If the Library as you
received it does not specify a version number of the GNU Lesser
General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

  If the Library as you received it specifies that a proxy can decide
whether future versions of the GNU Lesser General Public License shall
apply, that proxy's public statement of acceptance of any version is
permanent authorization for you to choose that version for the
Library.

AUTHORS file would be a big task in itself. On the other hand, we
now use git and I make sure that each author receives proper credit
for patches I receive.

So rather than trying to reproduce the git author log here (and
often making mistakes in that), I invite you to check the git logs.
You can also do this online at

 * routines provide generic parsing aid as well some fairly
 * complex routines targeted toward specific needs.
 *
 * General information - read this:
 * All routines work on a single CStr object, which must be supplied
 * during construction. The parse class keeps an internal pointer of
 * where the next parse operation is to start (you could also say
 * this is where the last parse operation stopped).
 *
 * Each parse operation carried out by this package starts from the
 * parse pointer, parses the caller-requested element (e.g. an
 * integer or delemited string) and the update the parse pointer. If
 * the caller tries to parse beyond the end of the original string,
 * an error is returned. In general, all functions return a parsRet
 * error code and all require the parseObj to be the first parameter.
 * The to-be-parsed string provided to the parse object MUST NOT be
 * freed or modified by the caller during the lifetime of the parse
 * object. However, the caller must free it when it is no longer needed.
 * Optinally, the parse object can be instructed to do that. All objects
 * returned by the parse routines must be freed by the caller. For
 * simpler data types (like integers), the caller must provide the
 * necessary buffer space.

\`configure' configures rsyslog 7.4.4 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/rsyslog]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

Some influential environment variables:
  CC          C compiler command
  CFLAGS      C compiler flags
  LDFLAGS     linker flags, e.g. -L if you have libraries in a
              nonstandard directory 
  LIBS        libraries to pass to the linker, e.g. -l
  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
              you have headers in a nonstandard directory 
  CPP         C preprocessor
  YACC        The `Yet Another Compiler Compiler' implementation to use.
              Defaults to the first program found out of: `bison -y', `byacc',
              `yacc'.
  YFLAGS      The list of arguments that will be passed by default to $YACC.
              This script will default YFLAGS to the empty string to avoid a
              default value of `-d' given by some make applications.

 *
 * Implementation of the action object.
 *
 * File begun on 2007-08-06 by RGerhards (extracted from syslogd.c)
 *
 * Some notes on processing (this hopefully makes it easier to find
 * the right code in question): For performance reasons, this module
 * uses different methods of message submission based on the user-selected
 * configuration. This code is similar, but can not be abstracted because
 * of the performance-affecting differences in it. As such, it is often
 * necessary to triple-check that everything works well in *all* modes.
 * The different modes (and calling sequence) are:
 *
 * if set iExecEveryNthOccur > 1 || iSecsExecOnceInterval
 * - doSubmitToActionQComplexBatch
 * - helperSubmitToActionQComplexBatch
 * - doActionCallAction
 *   handles mark message reduction, but in essence calls
 * - actionWriteToAction
 * - qqueueEnqObj
 *   (now queue engine processing)
 * if(pThis->bWriteAllMarkMsgs == RSFALSE) - this is the DEFAULT
 * - doSubmitToActionQNotAllMarkBatch
 * - doSubmitToActionQBatch (and from here like in the else case below!)
 * else
 * - doSubmitToActionQBatch
 * - doSubmitToActionQ
 * - qqueueEnqObj
 *   (now queue engine processing)
 *
 * Note that bWriteAllMakrMsgs on or off creates almost the same processing.
 * The difference ist that if WriteAllMarkMsgs is not set, we need to
 * preprocess the batch and drop mark messages which are not yet due for
 * writing.
 *
 * After dequeue, processing is as follows:
 * - processBatchMain
 * - processAction
 * - submitBatch
 * - tryDoAction
 * - ...
 *
 * MORE ON PROCESSING, QUEUES and FILTERING
 * All filtering needs to be done BEFORE messages are enqueued to an
 * action. In previous code, part of the filtering was done at the
 * "remote end" of the action queue, which lead to problems in
 * non-direct mode (because then things run asynchronously). In order
 * to solve this problem once and for all, I have changed the code so
 * that all filtering is done before enq, and processing on the
 * dequeue side of action processing now always executes whatever is
 * enqueued. This is the only way to handle things consistently and
 * (as much as possible) in a queue-type agnostic way. However, it is
 * a rather radical change, which I unfortunately needed to make from
 * stable version 5.8.1 to 5.8.2. If new problems pop up, you now know
 * what may be their cause. In any case, the way it is done now is the
 * only correct one.
 * A problem is that, under fortunate conditions, we use the current
 * batch for the output system as well. This is very good from a performance
 * point of view, but makes the distinction between enq and deq side of
 * the queue a bit hard. The current idea is that the filter condition
 * alone is checked at the deq side of the queue (seems to be unavoidable
 * to do it that way), but all other complex conditons (like failover
 * handling) go into the computation of the filter condition. For
 * non-direct queues, we still enqueue only what is acutally necessary.
 * Note that in this case the rest of the code must ensure that the filter
 * is set to "true". While this is not perfect and not as simple as
 * we would like to see it, it looks like the best way to tackle that
 * beast.

/* This function returns the "current" time for this action. Current time
 * is not necessarily real-time. In order to enhance performance, current
 * system time is obtained the first time an action needs to know the time
 * and then kept cached inside the action structure. Later requests will
 * always return that very same time. Wile not totally accurate, it is far
 * accurate in most cases and considered "acurate enough" for all cases.
 * When changing the threading model, please keep in mind that this
 * logic needs to be changed should we once allow more than one parallel
 * call into the same action (object). As this is currently not supported,
 * we simply cache the time inside the action object itself, after it
 * is under mutex protection.
 * Side-note: the value -1 is used as tActNow, because it also is the
 * error return value of time(). So we would do a retry with the next
 * invocation if time() failed. Then, of course, we would probably already
 * be in trouble, but for the sake of performance we accept this very,
 * very slight risk.
 * This logic has been added as part of an overall performance improvment
 * effort inspired by David Lang. -- rgerhards, 2008-09-16
 * Note: this function does not use the usual iRet call conventions
 * because that would provide little to no benefit but complicate things
 * a lot. So we simply return the system time.
