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. rsyslog-8.2412.0/Makefile.am0000664000175000017500000002546614650736301011213 sbin_PROGRAMS = pkglib_LTLIBRARIES = pkgconfigdir = $(libdir)/pkgconfig EXTRA_DIST = \ README.md \ platform/README \ platform/freebsd/rsyslogd \ platform/slackware/rc.rsyslogd \ platform/redhat/rsyslog.conf \ contrib/README \ CONTRIBUTING.md \ COPYING \ COPYING.LESSER \ COPYING.ASL20 \ contrib/gnutls/ca.pem \ contrib/gnutls/cert.pem \ contrib/gnutls/key.pem SUBDIRS = compat runtime grammar . plugins/immark plugins/imuxsock plugins/imtcp plugins/imudp plugins/omtesting #

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 Rsyslog has a modular design. Consequently, there is a growing number of modules. See the HTML documentation for their full description. .TP .I omsnmp SNMP trap output module .TP .I omgssapi Output module for GSS-enabled syslog .TP .I ommysql Output module for MySQL .TP .I omrelp Output module for the reliable RELP protocol (prevents message loss). For details, see below at imrelp and the HTML documentation. It can be used like this: .IP *.* :omrelp:server:port .IP *.* :omrelp:192.168.0.1:2514 # actual sample .TP .I ompgsql Output module for PostgreSQL .TP .I omlibdbi Generic database output module (Firebird/Interbase, MS SQL, Sybase, SQLite, Ingres, Oracle, mSQL) .TP .I imfile Input module for text files .TP .I imudp Input plugin for UDP syslog. Replaces the deprecated -r option. Can be used like this: .IP $ModLoad imudp .IP $UDPServerRun 514 .TP .I imtcp Input plugin for plain TCP syslog. Replaces the deprecated -t option. Can be used like this: .IP $ModLoad imtcp .IP $InputTCPServerRun 514 .TP .TP .I imrelp 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 then the exclamation mark must occur before the equals sign, just use it intuitively. However, please note that there are some restrictions over the traditional BSD syslog behaviour. These restrictions stem back to sysklogd, exist probably since at least the 1990's and as such have always been in rsyslog. Namely, in BSD syslogd you can craft a selector like this: *.debug;local6.err The intent is to log all facilities at debug or higher, except for local6, which should only log at err or higher. Unfortunately, local6.err will permit error severity and higher, but will not exclude lower severity messages from facility local6. As an alternative, you can explicitly exclude all severities that you do not want to match. For the above case, this selector is equivalent to the BSD syslog selector: *.debug;local6.!=info;local6.!=notice;local6.!=warn An easier approach is probably to do if ... then based matching in script. .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 By default, files are not synced after each write. To enable syncing of log files globally, use either the "$ActionFileEnableSync" directive or the "sync" parameter to omfile. Enabling this option degrades performance and it is advised not to enable syncing unless you know what you are doing. To selectively disable syncing for certain files, you may prefix the file path with a minus sign ("-"). .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). Sockets for forwarded messages can be bound to a specific device using the "device" option for the omfwd module. .B Example: .RS action(type="omfwd" Target="192.168.0.1" Device="eth0" Port=514 Protocol="udp") .RE .sp In the example above, messages are forwarded via UDP to the machine 192.168.0.1 at port 514 over the device eth0. TCP can be used by setting Protocol to "tcp" in the above example. For Linux with VRF support, the device option is used to specify the VRF to send messages. .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 'stop' command with no further parameters. .sp .B Example: .RS *.* stop # 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 one 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 msg the MSG part of the message (aka "the message" ;)) .TP .B rawmsg the message exactly as it was received from the socket. Should be useful for debugging. .TP .B HOSTNAME hostname from the message .TP .B 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) .TP .B syslogtag TAG from the message .TP .B programname the "static" part of the tag, as defined by BSD syslogd. For example, when TAG is "named[12345]", programname is "named". .TP .B PRI PRI part of the message - undecoded (single value) .TP .B PRI-text the PRI part of the message in a textual form (e.g. "syslog.info") .TP .B IUT the monitorware InfoUnitType - used when talking to a MonitorWare backend (also for phpLogCon) .TP .B syslogfacility the facility from the message - in numerical form .TP .B syslogfacility-text the facility from the message - in text form .TP .B syslogseverity severity from the message - in numerical form .TP .B syslogseverity-text severity from the message - in text form .TP .B timegenerated timestamp when the message was RECEIVED. Always in high resolution .TP .B timereported timestamp from the message. Resolution depends on what was provided in the message (in most cases, only seconds) .TP .B TIMESTAMP alias for timereported .TP .B PROTOCOL-VERSION The contents of the PROTOCOL-VERSION field from IETF draft draft-ietf-syslog-protocol .TP .B STRUCTURED-DATA The contents of the STRUCTURED-DATA field from IETF draft draft-ietf-syslog-protocol .TP .B APP-NAME The contents of the APP-NAME field from IETF draft draft-ietf-syslog-protocol .TP .B PROCID The contents of the PROCID field from IETF draft draft-ietf-syslog-protocol .TP .B MSGID The contents of the MSGID field from IETF draft draft-ietf-syslog-protocol .TP .B $NOW The current date stamp in the format YYYY-MM-DD .TP .B $YEAR The current year (4-digit) .TP .B $MONTH The current month (2-digit) .TP .B $DAY The current day of the month (2-digit) .TP .B $HOUR The current hour in military (24 hour) time (2-digit) .TP .B $MINUTE The current minute (2-digit) .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. .SH FILES .PD 0 .TP .I /etc/rsyslog.conf Configuration file for .B rsyslogd .SH SEE ALSO .BR rsyslogd (8), .BR logger (1), .BR syslog (3) The complete documentation can be found in the doc folder of the rsyslog distribution or online at .RS .B https://www.rsyslog.com/doc/ .RE Please note that the man page reflects only a subset of the configuration options.

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. -l, --lib Select the crypto library to be used. Either "ossl" or "gcry". Defaults to "gcry" or whatever is currently available. -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. Refer to the list of supported algorithms below for the "gcry" library. The default algorithm for "gcry" is "AES128". For the "ossl" library, both the algorithm and mode are specified using this option, with "AES-128-CBC" as the default. -m, --mode Sets the ciphermode to be used. See below for supported modes. The default is "CBC". In case of "ossl" library, this options is ignored. -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 ==================== In case of "ossl", see "ALGORITHM FETCHING" in crypto(7) for further information. In case of "gcry" we basically support what libgcrypt supports and that is: 3DES CAST5 BLOWFISH AES128 AES192 AES256 TWOFISH TWOFISH128 ARCFOUR DES SERPENT128 SERPENT192 SERPENT256 RFC2268_40 SEED CAMELLIA128 CAMELLIA192 CAMELLIA256 SUPPORTED CIPHER MODES ====================== In case of "gcry", 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 -k keyfile -l ossl -a AES-256-CBC encryptedfile** Decrypts encryptedfile using ossl library with AES256 algorithm and CBC mode **rscryutil -k keyfile -l gcry -a AES256 -m CBC encryptedfile** Decrypts encryptedfile using gcry library with AES256 algorithm and CBC mode **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.

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 covers basic aspects of operation. .B For details and configuration examples, see the rsyslog.conf (5) .B man page and the online documentation at https://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 .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 originally targeted towards developers. .TP .B "\-d" Turns on debug mode. 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. To disable writing a pid file, use the reserved name "NONE" (all upper case!), so "-iNONE". .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). .TP .B "\-o " "fullconf" Generates a consolidated config file .I fullconf that contains all of rsyslog's configuration in a single file. Include files are exploded into that file in exactly the way rsyslog sees them. This option is useful for troubleshooting, especially if problems with the order of action processing is suspected. It may also be used to check for "unexepectedly" included config content. .TP .BI "\-C" This 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. .TP .B "\-v" Print version and exit. .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. .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 children 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 the .B "\-d" option, .B rsyslogd produces debugging information according to the .B RSYSLOG_DEBUG environment variable and the signals received. When run in foreground, the information is written to stdout. An additional output file can be specified using the .B RSYSLOG_DEBUGLOG environment variable. .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 Debug Turns on debugging and prevents forking. This is processed earlier in the startup than command line options (i.e. -d) and as such enables earlier debugging output. Mutually exclusive with DebugOnDemand. .IP DebugOnDemand Enables debugging but turns off debug output. The output can be toggled by sending SIGUSR1. Mutually exclusive with Debug. .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 .SH BUGS Please review the file BUGS for up-to-date information on known bugs and annoyances. .SH Further Information Please visit .BR https://www.rsyslog.com/doc/ for additional information, tutorials and a support forum. .SH SEE ALSO .BR rsyslog.conf (5), .BR logger (1), .BR syslog (2), .BR syslog (3), .BR services (5), .BR savelog (8) .LP .SH COLLABORATORS .B rsyslogd is derived from sysklogd sources, which in turn was taken from the BSD sources.

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); * -------------------------------------------------------------------------- * * Copyright 2008-2018 Rainer Gerhards and Adiscon GmbH. * * This file is part of the rsyslog runtime library. * * The rsyslog runtime library is free software: you can redistribute it and/or modify * it under the terms of the GNU Lesser General Public License as published by * the Free Software Foundation, either version 3 of the License, or * (at your option) any later version. * * The rsyslog runtime library 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.

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 acquired 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. * * File begun on 2008-01-04 by RGerhards * * Copyright 2008-2019 Rainer Gerhards and Adiscon GmbH. * * This file is part of the rsyslog runtime library. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * -or- * see COPYING.ASL20 in the source distribution * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #include "config.h" #include #include #include #include #include #include #define DEV_DEBUG 0 /* set to 1 to enable very verbose developer debugging messages */ /* how many objects are supported by rsyslogd? */ #define OBJ_NUM_IDS 100 /* TODO change to a linked list? info: 16 were currently in use 2008-02-29 */ #include "rsyslog.h" #include "syslogd-types.h" #include "srUtils.h" #include "obj.h" #include "stream.h" #include "modules.h" #include "errmsg.h" #include "cfsysline.h" #include "unicode-helper.h" #include "datetime.h" /* static data */ DEFobjCurrIf(obj) /* we define our own interface, as this is expected by some macros! */ DEFobjCurrIf(var) DEFobjCurrIf(module) DEFobjCurrIf(strm) static objInfo_t *arrObjInfo[OBJ_NUM_IDS]; /* array with object information pointers */ pthread_mutex_t mutObjGlobalOp; /* mutex to guard global operations of the object system */ /* cookies for serialized lines */ #define COOKIE_OBJLINE '<' #define COOKIE_PROPLINE '+' #define COOKIE_ENDLINE '>' #define COOKIE_BLANKLINE '.' /* forward definitions */ static rsRetVal FindObjInfo(const char *szObjName, objInfo_t **ppInfo); /* methods */ /* This is a dummy method to be used when a standard method has not been * implemented by an object.

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"). * * File begun on 2008-01-09 by RGerhards * 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 * to the object. * * Copyright 2008-2022 Rainer Gerhards and Adiscon GmbH. * * This file is part of the rsyslog runtime library. * * The rsyslog runtime library is free software: you can redistribute it and/or modify * it under the terms of the GNU Lesser General Public License as published by * the Free Software Foundation, either version 3 of the License, or * (at your option) any later version. * * The rsyslog runtime library 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.

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. * * Module begun 2008-04-16 by Rainer Gerhards * * Copyright 2008-2016 Rainer Gerhards and Adiscon GmbH. * * This file is part of the rsyslog runtime library. * * The rsyslog runtime library is free software: you can redistribute it and/or modify * it under the terms of the GNU Lesser General Public License as published by * the Free Software Foundation, either version 3 of the License, or * (at your option) any later version. * * The rsyslog runtime library 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.

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 . rsyslog-8.2412.0/contrib/0000775000175000017500000000000014723322657010670 5rsyslog-8.2412.0/contrib/imhttp/0000775000175000017500000000000014723322657012175 5rsyslog-8.2412.0/contrib/imhttp/Makefile.am0000664000175000017500000000033214650736301014141 pkglib_LTLIBRARIES = imhttp.la imhttp_la_SOURCES = imhttp.c imhttp_la_CPPFLAGS = -I$(top_srcdir) $(PTHREADS_CFLAGS) $(RSRT_CFLAGS) $(APU_CFLAGS) imhttp_la_LDFLAGS = -module -avoid-version $(CIVETWEB_LIBS) $(APU_LIBS) rsyslog-8.2412.0/contrib/imhttp/imhttp.c0000664000175000017500000011214414650736301013563 /* imhttp.c * This is an input module for receiving http input. * * This file is contribution of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License");

directory contains a number of possibly useful things that do not 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 adaptation. If you have something useful you would like to see in contrib, just drop us a note (see https://www.rsyslog.com for how to do that at the time your are reading this document). rgerhards, 2007-08-08 rsyslog-8.2412.0/contrib/ffaup/0000775000175000017500000000000014723322656011770 5rsyslog-8.2412.0/contrib/ffaup/Makefile.am0000664000175000017500000000031414650736301013735 # # ffaup support # pkglib_LTLIBRARIES = ffaup.la ffaup_la_SOURCES = ffaup.c ffaup_la_CPPFLAGS = $(PTHREADS_CFLAGS) $(RSRT_CFLAGS) ffaup_la_LDFLAGS = -module -avoid-version ffaup_la_LIBADD = $(FAUP_LIBS) rsyslog-8.2412.0/contrib/ffaup/ffaup.c0000664000175000017500000003005514650736301013153 /* ffaup.c * This is a function module for URL parsing. * * File begun on 2021/10/23 by TBertin * * Copyright 2007-2021 Theo Bertin for Advens * * This file is part of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * -or- * see COPYING.ASL20 in the source distribution * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #include #include #ifndef _AIX #include #endif #include #include #include #include #include #include #include "config.h" #include "rsyslog.h" #include "parserif.h" #include "module-template.h" #include "rainerscript.h" MODULE_TYPE_FUNCTION MODULE_TYPE_NOKEEP DEF_FMOD_STATIC_DATA faup_options_t *glbOptions = NULL; enum _faup_parse_type_t { FAUP_PARSE_ALL, FAUP_PARSE_SCHEME, FAUP_PARSE_CREDENTIAL, FAUP_PARSE_SUBDOMAIN, FAUP_PARSE_DOMAIN, FAUP_PARSE_DOMAIN_WITHOUT_TLD, FAUP_PARSE_HOST, FAUP_PARSE_TLD, FAUP_PARSE_PORT, FAUP_PARSE_RESOURCE_PATH, FAUP_PARSE_QUERY_STRING, FAUP_PARSE_FRAGMENT }; typedef enum _faup_parse_type_t faup_parse_type_t; static inline sbool check_param_count_faup(unsigned short nParams) { return nParams != 1; } static void ATTR_NONNULL() do_faup_parse(struct cnffunc *__restrict__ const func, struct svar *__restrict__ const ret, void *__restrict__ const usrptr, wti_t *__restrict__ const pWti, const faup_parse_type_t parse_type) { struct svar srcVal; int bMustFree; cnfexprEval(func->expr[0], &srcVal, usrptr, pWti); char *url = (char*) var2CString(&srcVal, &bMustFree); /* We use the faup_handler_t struct directly instead of calling faup_init to avoid overhead and useless allocations.

This file has the following characteristics : - the file name is compose of a prefix and the date of the file. - the lines of logs are produced by call to userlog() tuxedo method. - Tuxedo server based on JAVA writes java's exceptions as log lines in ULOG file. This version of the module ignores those lines. - The ECID (Execution Context ID) is extracted and placed as a structured data named ECID. ### Why this module instead of using imfile As the file name is a rotation base of the current date, imfile must use a glob to manage this rotation. Imfile must use fs notify implement of the OS. This interface is implemented in imfile for Linux and Solaris but not AIX. Like imfile does, this module is using the same rsyslog core stream and then gets advantages its evolves. Primary we tried to integrating in imfile a "glob like" in polling mode, it increased the module complexity and make it unmaintainable. So imfile could not be a valid candidate on none fs notification OS like AIX. ### Ulog log samples This are different case of logs in the ULOG file according to the usage.

REQUIREMENTS: * libsodium ( https://github.com/jedisct1/libsodium ) * zeromq built with libsodium support ( http://zeromq.org/ ) * czmq ( http://czmq.zeromq.org/ ) EXPLANATION OF OPTIONS Module ------ servercertpath: path to server cert if using CURVE clientcertpath: path to client cert(s) if using CURVE authtype: CURVESERVER, CURVECLIENT (omit for no auth) authenticator: whether to start an authenticator thread Action ------ type: type of action (omczmq for this plugin) endpoints: comma delimited list of zeromq endpoints (see zeromq documentation) socktype: zeromq socket type (currently supports PUSH, PUB, DEALER, RADIO, CLIENT, SCATTER) sendtimeout: timeout in ms before send errors sendhwm: number of messages to store in internal buffer before discarding (defaults to 1000) connecttimeout: connection timeout in ms(requires libzmq 4.2 or higher) heartbeativl: time in ms between sending heartbeat PING messages (requires libzmq 4.2 or higher) heartbeattimeout: time in milliseconds to wait for a PING response before disconnect(libzmq 4.2 or higher) heartbeatttl: time remote peer should wait between PINGs before disconnect (libzmq 4.2 or higher) topicframe: "on" to send topic as separate frame if PUB socket topics: comma delimited list of topics or templates to make topics from if PUB or RADIO socket dynatopic: if "on" topics list is treated as list of template names template: template to use for message (defaults to RSYSLOG_ForwardFormat) EXAMPLE CONFIGURATION This configuration sets up an omczmq endpoint as a ZMQ_PUB socket with CURVE authentication. Clients whose certificates are in the '/etc/curve.d/allowed_clients/' directory will be allowed to connect. Each message is published on two topics ( "hostname.programname" and "programname.hostname" ) which are constructed from properties of the log message. For instance, a log from sshd from host.example.com will be published on two topics: * host.example.com.sshd * sshd.host.example.com In this configuration, the output is configured to send each message as a two frame message, with the topic in the first flame and the rsyslog message in the second. ------------------------------------------------------------------------------- module( load="omczmq" servercertpath="/etc/curve.d/example_server" clientcertpath="/etc/curve.d/allowed_clients" authtype="CURVESERVER" authenticator="on" ) template(name="host_program_topic" type="list") { property(name="hostname") constant(value=".") property(name="programname") } template(name="program_host_topic" type="list") { property(name="programname") constant(value=".") property(name="hostname") } action( name="to_zeromq" type="omczmq" socktype="PUB" endpoints="@tcp://*:31338" topics="host_program_topic,program_host_topic" dynatopic="on" topicframe="on" ) ------------------------------------------------------------------------------- rsyslog-8.2412.0/contrib/omczmq/Makefile.am0000664000175000017500000000033714650736301014147 pkglib_LTLIBRARIES = omczmq.la omczmq_la_SOURCES = omczmq.c omczmq_la_CPPFLAGS = $(RSRT_CFLAGS) $(PTHREADS_CFLAGS) $(CZMQ_CFLAGS) omczmq_la_LDFLAGS = -module -avoid-version omczmq_la_LIBADD = $(CZMQ_LIBS) EXTRA_DIST = rsyslog-8.2412.0/contrib/omczmq/omczmq.c0000664000175000017500000004324714650736301013574 /* omczmq.c * Copyright (C) 2016 Brian Knox * Copyright (C) 2014 Rainer Gerhards * * Author: Brian Knox * * Licensed under the Apache License, Version 2.0 (the "License");

populate the * structured data portion of the messages JSON. There are two reasons * for this: * 1. robustness * - this guard against misconfiguration * - it permits us to be more liberal in regard to malformed * structured data * - it permits us to handle border-cases (like duplicate * SD-IDs) with much less complexity * 2. performance * With being "on the spot" of what we need we can reduce memory * reads and writes. This is a considerable save if the JSON representation * is not otherwise needed. * * Note that the recommended calling sequence if both of these modules * are used is * * 1. mmrfc5424addhmac * 2. mmpstrucdata * * This sequence permits mmpstrucdata to pick up the modifications we * made in this module here. * * Copyright 2013 Adiscon GmbH. * * This file is part of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * -or- * see COPYING.ASL20 in the source distribution * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #include "config.h" #include "rsyslog.h" #include #include #include #include #include #include #include #include #include #include #include "conf.h" #include "syslogd-types.h" #include "srUtils.h" #include "template.h" #include "module-template.h" #include "errmsg.h" MODULE_TYPE_OUTPUT MODULE_TYPE_NOKEEP MODULE_CNFNAME("mmrfc5424addhmac") DEF_OMOD_STATIC_DATA /* config variables */ typedef struct _instanceData { uchar *key; int16_t keylen; /* cached length of key, to avoid recomputation */ uchar *sdid; /* SD-ID to be used to persist the hmac */ int16_t sdidLen; const EVP_MD *algo; } instanceData; typedef struct wrkrInstanceData { instanceData *pData; } wrkrInstanceData_t; struct modConfData_s { rsconf_t *pConf; /* our overall config object */ }; static modConfData_t *loadModConf = NULL;/* modConf ptr to use for the current load process */ static modConfData_t *runModConf = NULL;/* modConf ptr to use for the current exec process */ /* tables for interfacing with the v6 config system */ /* action (instance) parameters */ static struct cnfparamdescr actpdescr[] = { { "key", eCmdHdlrString, 1 }, { "hashfunction", eCmdHdlrString, 1 }, { "sd_id", eCmdHdlrGetWord, 1 } }; static struct cnfparamblk actpblk = { CNFPARAMBLK_VERSION, sizeof(actpdescr)/sizeof(struct cnfparamdescr), actpdescr }; BEGINbeginCnfLoad CODESTARTbeginCnfLoad loadModConf = pModConf; pModConf->pConf = pConf; ENDbeginCnfLoad BEGINendCnfLoad CODESTARTendCnfLoad ENDendCnfLoad BEGINcheckCnf CODESTARTcheckCnf ENDcheckCnf BEGINactivateCnf CODESTARTactivateCnf runModConf = pModConf; ENDactivateCnf BEGINfreeCnf CODESTARTfreeCnf ENDfreeCnf BEGINcreateInstance CODESTARTcreateInstance ENDcreateInstance BEGINcreateWrkrInstance CODESTARTcreateWrkrInstance ENDcreateWrkrInstance BEGINisCompatibleWithFeature CODESTARTisCompatibleWithFeature ENDisCompatibleWithFeature BEGINfreeInstance CODESTARTfreeInstance ENDfreeInstance BEGINfreeWrkrInstance CODESTARTfreeWrkrInstance ENDfreeWrkrInstance static inline void setInstParamDefaults(instanceData *pData) { pData->key = NULL; } BEGINnewActInst struct cnfparamvals *pvals; char *ciphername; int i; CODESTARTnewActInst DBGPRINTF("newActInst (mmrfc5424addhmac)\n"); if((pvals = nvlstGetParams(lst, &actpblk, NULL)) == NULL) { ABORT_FINALIZE(RS_RET_MISSING_CNFPARAMS); } CODE_STD_STRING_REQUESTnewActInst(1) CHKiRet(OMSRsetEntry(*ppOMSR, 0, NULL, OMSR_TPL_AS_MSG)); CHKiRet(createInstance(&pData)); setInstParamDefaults(pData); for(i = 0 ; i < actpblk.nParams ; ++i) { if(!pvals[i].bUsed) continue; if(!strcmp(actpblk.descr[i].name, "key")) { pData->key = (uchar*)es_str2cstr(pvals[i].val.d.estr, NULL); pData->keylen = es_strlen(pvals[i].val.d.estr); } else if(!strcmp(actpblk.descr[i].name, "hashfunction")) { ciphername = es_str2cstr(pvals[i].val.d.estr, NULL); pData->algo = EVP_get_digestbyname(ciphername); if(pData->algo == NULL) { LogError(0, RS_RET_CRY_INVLD_ALGO, "hashFunction '%s' unknown to openssl - " "cannot continue", ciphername); free(ciphername); ABORT_FINALIZE(RS_RET_CRY_INVLD_ALGO); } free(ciphername); } else if(!strcmp(actpblk.descr[i].name, "sd_id")) { pData->sdid = (uchar*)es_str2cstr(pvals[i].val.d.estr, NULL); pData->sdidLen = es_strlen(pvals[i].val.d.estr); } else { dbgprintf("mmrfc5424addhmac: program error, non-handled " "param '%s'\n", actpblk.descr[i].name); } } CODE_STD_FINALIZERnewActInst cnfparamvalsDestruct(pvals, &actpblk); ENDnewActInst BEGINdbgPrintInstInfo CODESTARTdbgPrintInstInfo ENDdbgPrintInstInfo BEGINtryResume CODESTARTtryResume ENDtryResume /* turn the binary data in bin of length len into a * printable hex string.

reading full text file data. A text file is a * non-binary file who's lines are delimited by the \n character. The file is * treated as a single message. An optional structured data can be written at * the end of the file. * * No state file are used as it should only grow with time. Instead the state * is managed using the name of the file. A "glob" allows the module to identify * "to be treated" files. The module can be configured either to deleted the * the file on success either to rename the file on success. The size limit is * fixed by rsyslog max message size global parameter. All files larger than this * limit produce a message which references it as "too large" and its new location * The "too large" files are also renamed to keep them available. * * This modules allows one to centralize batch reports with other standard logs and * performance monitoring in a single repository (ElasticSearch, HDFS, ...). This * centralization helps to identify cause of global performance issues. * * Work originally begun on 2014-07-01 by Philippe Duveau @ Pari Mutuel Urbain * * This file is contribution of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * -or- * see COPYING.ASL20 in the source distribution * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #include "config.h" #include #include #include #include #include #include #include /* do NOT remove: will soon be done by the module generation macros */ #include #include #include #include #ifdef HAVE_SYS_STAT_H # include #endif #include "rsyslog.h" /* error codes etc... */ #include "dirty.h" #include "cfsysline.h" /* access to config file objects */ #include "module-template.h" #include "srUtils.h" /* some utility functions */ #include "msg.h" #include "errmsg.h" #include "glbl.h" #include "datetime.h" #include "unicode-helper.h" #include "prop.h" #include "stringbuf.h" #include "ruleset.h" #include "ratelimit.h" #include MODULE_TYPE_INPUT /* must be present for input modules, do not remove */ MODULE_TYPE_NOKEEP MODULE_CNFNAME("imbatchreport") /* defines for freebsd */ #ifndef O_LARGEFILE #define O_LARGEFILE 0 #endif /* Module static data */ DEF_IMOD_STATIC_DATA /* must be present, starts static data */ DEFobjCurrIf(glbl) DEFobjCurrIf(ruleset) DEFobjCurrIf(datetime) DEFobjCurrIf(prop) #define SRUCTDATA_BUFFER_LEN 150 #define READ_BUFFER_LEN 512 #define FILE_TOO_LARGE "File too large : " #define FILE_TOO_LARGE_LEN sizeof(FILE_TOO_LARGE)-1 #define DFLT_PollInterval 10 #define ADD_METADATA_UNSPECIFIED -1 typedef enum action_batchreport_t { action_nothing, action_rename, action_delete } action_batchreport_t; struct instanceConf_s { uchar *pszFollow_glob; uchar *pszDirName; uchar *pszFileBaseName; uchar *pszTag; int lenTag; uchar *pszTSk; int lenTSk; uchar *pszProgk; int lenProgk; int must_stop; uchar *pszBindRuleset; int bDedupSpace; int iFacility; int iSeverity; char *ff_regex; /* Full treatment : this should contain a regex applied on filename.

messages via an AMQP 1.0-compatible messaging bus. This module requires the Apache QPID Proton python library, version 0.10+. This should be installed on the system that is running rsyslogd. ## Message Format ## Messages sent from this module to the message bus contain a list of strings. Each string is a separate log message. The list is ordered such that the oldest log appears at the front of the list, whilst the most recent log is at the end of the list. ## Configuration ## This module is configured via the rsyslog.conf configuration file. To use this module it must first be imported. Example: module(load="omamqp1") Actions can then be created using this module. Example: action(type="omamqp1" host="localhost:5672" target="amq.topic") The following parameters are recognized by the module: * host - The address of the message bus. Optionally a port can be included, separated by a ':'. Example: "localhost:5672" * target - The destination for the generated messages. This can be the name of a queue or topic. On some messages buses it may be necessary to create this target manually. Example: "amq.topic" * username - Optional. Used by SASL to authenticate with the message bus. * password - Optional. Used by SASL to authenticate with the message bus. * template - Template to use to format the record. Defaults to `RSYSLOG_FileFormat` * idleTimeout - The idle timeout in seconds. This enables connection heartbeats and is used to detect a failed connection to the message bus. Set to zero to disable. * maxResend - number of times an undeliverable message is re-sent to the message bus before it is dropped. This is unrelated to rsyslog's action.resumeRetryCount. Once the connection to the message bus is active this module is ready to receive log messages from rsyslog (i.e. the module has 'resumed'). Even though the connection is active, any particular message may be rejected by the message bus (e.g. 'unrouteable'). The module will retry (e.g. 'suspend') for up to maxResend attempts before discarding the message as undeliverable. Setting this to zero disables the limit and unrouteable messages will be retried as long as the connection stays up. You probably do not want that to happen. The default is 10. * reconnectDelay - The time in seconds this module will delay before attempting to re-established a failed connection (default 5 seconds). * disableSASL - Setting this to a non-zero value will disable SASL negotiation. Only necessary if the message bus does not offer SASL. ## Dependencies ## The package is dependent on the QPID Proton AMQP 1.0 library. To build this package you must also have the QPID Proton C headers installed. Pre-built packages are available for Fedora 22+ via the base Fedora repos. Packages for RHEL/Centos based systems can be obtained via [EPEL](https://fedoraproject.org/wiki/EPEL). In order to build the module, install the _qpid-proton-c-devel_ package. Pre-built packages from most Ubuntu/Debian systems are available via the [QPID project's PPA on Launchpad](https://launchpad.net/~qpid). For example, to install the latest version of the Proton packages (as of this writing): $ sudo add-apt-repository ppa:qpid/released $ sudo apt-get update $ sudo apt-get install libqpid-proton3 libqpid-proton3-dev Check your distribution for the availability of Proton packages. Alternatively, you can pull down the Proton code from the [project website](http://qpid.apache.org/) and build it yourself. ## Debugging ## Debug logging can be enabled using the environment variables `RSYSLOG_DEBUG` and `RSYSLOG_DEBUGLOG`, export RSYSLOG_DEBUG=debug export RSYSLOG_DEBUGLOG=/tmp/rsyslog.debug.log or with the old-style rsyslog debug configuration settings. For example: $DebugFile /tmp/omamqp1-debug.txt $DebugLevel 2 There are a number of tracepoints within the omamqp1.c code. ---- ## Notes on use with the QPID C++ broker (qpidd) ## _Note well: These notes assume use of version 0.34 of the QPID C++ broker. Previous versions may not be fully compatible_ To use the Apache QPID C++ broker _qpidd_ as the message bus, a version of qpidd that supports the AMQP 1.0 protocol must be used. Since qpidd can be packaged without AMQP 1.0 support you should verify AMQP 1.0 has been enabled by checking for AMQP 1.0 related options in the qpidd help text. For example: qpidd --help ... AMQP 1.0 Options: --domain DOMAIN Domain of this broker --queue-patterns PATTERN Pattern for on-demand queues --topic-patterns PATTERN Pattern for on-demand topics If no AMQP 1.0 related options appear in the help output, then AMQP 1.0 has not been included with your qpidd. The destination for message (target) must be created before log messages arrive. This can be done using the qpid-config tool. Example: qpid-config add queue rsyslogd Alternatively, the target can be created on demand by configuring a queue-pattern (or topic-pattern) that matches the target. To do this, add a _queue-patterns_ (or _topic_patterns_) directive to the qpidd configuration file /etc/qpid/qpidd.conf. For example, to have qpidd automatically create a queue named _rsyslogd_, add the following to the qpidd configuration file: queue-patterns=rsyslogd or, if a topic is desired instead of a queue: topic-patterns=rsyslogd These dynamic targets are auto-delete and will be destroyed once there are no longer any subscribers or queue-bound messages. Versions of qpidd <= 0.34 also need to have the SASL service name set to 'amqp'. Add this to the qpidd.conf file: sasl-service-name=amqp ---- ## Notes on use with the QPID Dispatch Router (qdrouterd) ## _Note well: These notes assume use of version 0.5 of the QPID Dispatch Router Previous versions may not be fully compatible_ The default qdrouterd configuration does not have SASL authentication turned on. You must set up SASL in the qdrouter configuration file /etc/qpid-dispatch/qdrouterd.conf First create a SASL configuration file for qdrouterd. This configuration file is usually /etc/sasl2/qdrouterd.conf, but its default location may vary depending on your platform's configuration. This document assumes you understand how to properly configure SASL. Here is an example qdrouterd SASL configuration file that allows the client to use the DIGEST-MD5 or PLAIN authentication mechanisms, plus a SASL user database: pwcheck_method: auxprop auxprop_plugin: sasldb sasldb_path: /var/lib/qdrouterd/qdrouterd.sasldb mech_list: DIGEST-MD5 PLAIN Once a SASL configuration file has been set up for qdrouterd the path to the directory holding the configuration file and the basename of the configuration file (sas '.conf') must be added to the /etc/qpid-dispatch/qdrouterd.conf configuration file. This is done by adding _saslConfigPath_ and _saslConfigName_ to the _container_ section of the configuration file. For example, assuming the file /etc/sasl2/qdrouter.conf holds the qdrouterd SASL configuration: container { workerThreads: 4 containerName: Qpid.Dispatch.Router.A saslConfigPath: /etc/sasl2 saslConfigName: qdrouterd } In addition, the address used by the omamqp1 module to connect to qdrouterd must have SASL authentication turned on. This is done by adding the _authenticatePeer_ attribute set to 'yes' to the corresponding _listener_ entry: listener { addr: 0.0.0.0 port: amqp authenticatePeer: yes } This should complete the SASL setup needed by qdrouterd. The target address used as the destination for the log messages must be picked with care. qdrouterd uses the prefix of the target address to determine the forwarding pattern used for messages sent using that target address. Addresses starting with the prefix _queue_ are distributed to only one message receiver. If there are multiple message consumers listening to that target address, only one listener will receive the message. In this case, qdrouterd will load balance messages across the multiple consumers - much like a queue with competing subscribers. For example: "queue/rsyslogd" If a multicast pattern is desired - where all active listeners receive their own copy of the message - the target address prefix _multicast_ may be used. For example: "multicast/rsyslogd" Note well: if there are _no_ active receivers for the log messages, messages will be rejected the qdrouterd. In this case the omamqp1 module will return a _SUSPENDED_ result to the rsyslogd main task. rsyslogd may then re-submit the rejected log messages to the module, which will attempt to send them again. This retry option is configured via rsyslogd - it is not part of this module. Refer to the rsyslogd actions documentation. ---- ### Using qdrouterd in combination with qpidd ### A qdrouterd-based message bus can use a broker as a message storage mechanism for those that require broker-based message services (such as a message store). This section explains how to configure qdrouterd and qpidd for this type of deployment. Please read the notes for deploying qpidd and qdrouterd first. Each qdrouterd instance that is to connect the broker to the message bus must define a _connector_ section in the qdrouterd.conf file. This connector contains the addressing information necessary to have the message bus set up a connection to the broker. For example, if a broker is available on host broker.host.com at port 5672: connector { name: mybroker role: on-demand addr: broker.host.com port: 5672 } In order to route messages to and from the broker, a static _link route_ must be configured on qdrouterd. This link route contains a target address prefix and the name of the connector to use for forwarding matching messages. For example, to have qdrouterd forward messages that have a target address prefixed by 'Broker' to the connector defined above, the following link pattern must be added to the qdrouterd.conf configuration: linkRoutePattern { prefix: /Broker/ connector: mybroker } A queue must then be created on the broker. The name of the queue must be prefixed by the same prefix specified in the linkRoutePattern entry. For example: $ qpid-config add queue Broker/rsyslogd Lastly, use the name of the queue for the target address used by the omamqp module. For example, assuming qdrouterd is listening on local port 5672: action(type="omamqp1" host="localhost:5672" target="Broker/rsyslogd") # Tests ## Valgrind For investigating leaks, valgrind will not give you the full symbols in the stack because rsyslog unloads the module before the leak checker finishes. The test adds the following using `add_conf` add_conf ' global(debug.unloadModules="off") ' Then you should get a full stacktrace with full symbols. rsyslog-8.2412.0/contrib/omamqp1/omamqp1.c0000664000175000017500000006467714650736301013720 /* * Licensed to the Apache Software Foundation (ASF) under one * or more contributor license agreements.

using hiredis library REQUIREMENTS: * hiredis ( https://github.com/redis/hiredis.git ) USAGE: This plugin has two current "modes" that it supports: 1. "queue" The queue mode will LPOP or RPOP your message from a redis list. Following parameters are required: - mode: Set mode to "queue" to enable the queue mode - key: The key to xPOP on - server: The name or IP address of the redis server - port: The redis listening port Following parameters are optional: - password: If set, the plugin will issue an "AUTH" command before calling xPOP - uselpop: If set to "1", LPOP will be used instead of default RPOP Redis pipelining is used inside the worker thread. The dequeue batch size is configured with the "batchsize" parameter (default is 10). Imhiredis will query Redis every second to see if entries are in the list, if that's the case they will be dequeued continuously by batches of "batchsize elements" until none remains. Due to its balance between polling interval and pipelining and its use of lists, this mode is quite performant and reliable. However, due to the 1 second polling frequency, one may consider using the `subscribe` mode instead if very low latency is required. ``` module(load="imhiredis") input( type="imhiredis" mode="queue" key="vulture" server="127.0.0.1" port="6379" uselpop="1" password="foobar" batchsize="10" ) ``` 2. "subscribe" The subscribe mode will SUBSCRIBE to a redis channel. The "key" parameter is required and will be used for the subscribe channel. Following parameters are required: - mode: Set mode to "subscribe" to enable the subscribe mode - key: The key to subscribe to (aka the "channel") - server: The name or IP address of the redis server - port: The redis listening port Following parameters are optional: - password: If set, the plugin will issue an "AUTH" command before listening to a channel - uselpop: If set to "1", LPOP will be used instead of default RPOP ``` module(load="imhiredis") input( type="imhiredis" mode="subscribe" key="vulture" server="127.0.0.1" port="6379" password="foobar" batchsize="10" ) ``` TODO * TLS support rsyslog-8.2412.0/contrib/imhiredis/Makefile.am0000664000175000017500000000036414650736301014616 pkglib_LTLIBRARIES = imhiredis.la imhiredis_la_SOURCES = imhiredis.c imhiredis_la_CPPFLAGS = $(RSRT_CFLAGS) $(PTHREADS_CFLAGS) $(HIREDIS_CFLAGS) imhiredis_la_LDFLAGS = -module -avoid-version imhiredis_la_LIBADD = $(HIREDIS_LIBS) EXTRA_DIST = rsyslog-8.2412.0/contrib/imhiredis/COPYING0000664000175000017500000010437014650736301013617 GNU GENERAL PUBLIC LICENSE 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.

[http://sskaje.me/](http://sskaje.me/)) OmHTTPFS is an Rsyslog plugin writing data to HDS via *Hadoop HDFS over HTTP*. ## Hadoop HDFS over HTTP Official site: [Hadoop HDFS over HTTP](http://hadoop.apache.org/docs/current/hadoop-hdfs-httpfs/index.html) HTTPFS is not well documented. I tried to read its source and write an [intro with examples](http://sskaje.me/2014/08/doc-for-httpfs/), until I found [Administering the file system by using HttpFS REST APIs](http://www-01.ibm.com/support/knowledgecenter/SSPT3X_2.1.2/com.ibm.swg.im.infosphere.biginsights.admin.doc/doc/admin_fileupload_rest_apis.html) by IBM. ## OmHDFS for Rsyslog Rsyslog provides a plugin named omHDFS which requires lots of work compiling and configuring, and it's not that usable. Here is what I tried before writing this omhttpfs: [Build omhdfs for Rsyslog](http://sskaje.me/2014/08/build-omhdfs-rsyslog/). ## Rsyslog config Legacy config **NOT** supported. Example: ``` module(load="omhttpfs") template(name="hdfs_tmp_file" type="string" string="/tmp/%$YEAR%/test.log") template(name="hdfs_tmp_filecontent" type="string" string="%$YEAR%-%$MONTH%-%$DAY% %MSG% ==\n") local4.* action(type="omhttpfs" host="10.1.1.161" port="14000" https="off" file="hdfs_tmp_file" isDynFile="on") local5.* action(type="omhttpfs" host="10.1.1.161" port="14000" https="off" file="hdfs_tmp_file" isDynFile="on" template="hdfs_tmp_filecontent") ``` Tested with CDH 5.2.0 + Rsyslog 8.6.0 on CentOS 7 \# EOF rsyslog-8.2412.0/contrib/omhttpfs/omhttpfs.c0000664000175000017500000005217614723322534014471 /* omhttpfs.c * Send all output to HDFS via httpfs * * Author: sskaje (sskaje@gmail.com, http://sskaje.me/) * * Licensed under the Apache License, Version 2.0 (the "License");

hostnametagotherstuff * * The tabs can be represented in different ways. This module will auto-detect the tab representation based on * the global config settings, but they can be overridden for each instance in the config file if needed. * * 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 * * Interesting 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 * * * created 2010-12-13 by David Lang based on pmlastmsg * Modified 2017-05-29 by Shane Lawrence. * * This file is part of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License");

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.

USAGE: This plugin has three current "modes" that it supports: 1. "template" This is the original mode that the plugin supported. You use an rsyslog template to construct a command that is sent directly to redis. This mode currently has an issue dealing with strings that contain spaces. It's useful for doing things like incrementing counters for statistics. ``` module(load="omhiredis") template( name="simple_count" type="string" string="HINCRBY testcount %programname% 1") *.* action( name="count_redis" type="omhiredis" mode="template" template="simple_count" ) ``` 2. "queue" The queue mode will LPUSH your message to a redis list. Unlike the template mode, it handles full rsyslog messages properly. If a template is not supplied, it will default to the RSYSLOG_ForwardFormat template. The "key" parameter is required. ``` module(load="omhiredis") *.* action( name="push_redis" type="omhiredis" mode="queue" key="testqueue" ) ``` 3. "publish" The publish mode will PUBLISH to a redis channel. Unlike the template mode, it handles full rsyslog messages properly. If a template is not supplied, it will default to the RSYSLOG_ForwardFormat template. The "key" parameter is required and will be used for the publish channel. ``` module(load="omhiredis") *.* action( name="publish_redis" type="omhiredis" mode="publish" key="testpublish" ) ``` NOTES * dequeuebatchsize now sets the pipeline size for hiredis, allowing pipelining commands. rsyslog-8.2412.0/contrib/omhiredis/omhiredis.c0000664000175000017500000006066614650736301014732 /* omhiredis.c * Copyright 2012 Talksum, Inc * Copyright 2015 DigitalOcean, Inc * * This program is free software: you can redistribute it and/or * modify it under the terms of the GNU Lesser 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.

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 . rsyslog-8.2412.0/contrib/omhiredis/Makefile.in0000664000175000017500000006312114723322620014631 # Makefile.in generated by automake 1.16.5 from Makefile.am. # @configure_input@ # Copyright (C) 1994-2021 Free Software Foundation, Inc. # This Makefile.in is free software; the Free Software Foundation # gives unlimited permission to copy and/or distribute it, # with or without modifications, as long as this notice is preserved. # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY, to the extent permitted by law; without # even the implied warranty of MERCHANTABILITY or FITNESS FOR A # PARTICULAR PURPOSE. @SET_MAKE@ VPATH = @srcdir@ am__is_gnu_make = { \ if test -z '$(MAKELEVEL)'; then \ false; \ elif test -n '$(MAKE_HOST)'; then \ true; \ elif test -n '$(MAKE_VERSION)' && test -n '$(CURDIR)'; then \ true; \ else \ false; \ fi; \ } am__make_running_with_option = \ case $${target_option-} in \ ?) ;; \ *) echo "am__make_running_with_option: internal error: invalid" \ "target option '$${target_option-}' specified" >&2; \ exit 1;; \ esac; \ has_opt=no; \ sane_makeflags=$$MAKEFLAGS; \ if $(am__is_gnu_make); then \ sane_makeflags=$$MFLAGS; \ else \ case $$MAKEFLAGS in \ *\\[\ \ ]*) \ bs=\\; \ sane_makeflags=`printf '%s\n' "$$MAKEFLAGS" \ | sed "s/$$bs$$bs[$$bs $$bs ]*//g"`;; \ esac; \ fi; \ skip_next=no; \ strip_trailopt () \ { \ flg=`printf '%s\n' "$$flg" | sed "s/$$1.*$$//"`; \ }; \ for flg in $$sane_makeflags; do \ test $$skip_next = yes && { skip_next=no; continue; }; \ case $$flg in \ *=*|--*) continue;; \ -*I) strip_trailopt 'I'; skip_next=yes;; \ -*I?*) strip_trailopt 'I';; \ -*O) strip_trailopt 'O'; skip_next=yes;; \ -*O?*) strip_trailopt 'O';; \ -*l) strip_trailopt 'l'; skip_next=yes;; \ -*l?*) strip_trailopt 'l';; \ -[dEDm]) skip_next=yes;; \ -[JT]) skip_next=yes;; \ esac; \ case $$flg in \ *$$target_option*) has_opt=yes; break;; \ esac; \ done; \ test $$has_opt = yes am__make_dryrun = (target_option=n; $(am__make_running_with_option)) am__make_keepgoing = (target_option=k; $(am__make_running_with_option)) pkgdatadir = $(datadir)/@PACKAGE@ pkgincludedir = $(includedir)/@PACKAGE@ pkglibdir = $(libdir)/@PACKAGE@ pkglibexecdir = $(libexecdir)/@PACKAGE@ am__cd = CDPATH="$${ZSH_VERSION+.}$(PATH_SEPARATOR)" && cd install_sh_DATA = $(install_sh) -c -m 644 install_sh_PROGRAM = $(install_sh) -c install_sh_SCRIPT = $(install_sh) -c INSTALL_HEADER = $(INSTALL_DATA) transform = $(program_transform_name) NORMAL_INSTALL = : PRE_INSTALL = : POST_INSTALL = : NORMAL_UNINSTALL = : PRE_UNINSTALL = : POST_UNINSTALL = : build_triplet = @build@ host_triplet = @host@ subdir = contrib/omhiredis ACLOCAL_M4 = $(top_srcdir)/aclocal.m4 am__aclocal_m4_deps = $(top_srcdir)/m4/ac_check_define.m4 \ $(top_srcdir)/m4/atomic_operations.m4 \ $(top_srcdir)/m4/atomic_operations_64bit.m4 \ $(top_srcdir)/m4/libtool.m4 $(top_srcdir)/m4/ltoptions.m4 \ $(top_srcdir)/m4/ltsugar.m4 $(top_srcdir)/m4/ltversion.m4 \ $(top_srcdir)/m4/lt~obsolete.m4 $(top_srcdir)/configure.ac am__configure_deps = $(am__aclocal_m4_deps) $(CONFIGURE_DEPENDENCIES) \ $(ACLOCAL_M4) DIST_COMMON = $(srcdir)/Makefile.am $(am__DIST_COMMON) mkinstalldirs = $(install_sh) -d CONFIG_HEADER = $(top_builddir)/config.h CONFIG_CLEAN_FILES = CONFIG_CLEAN_VPATH_FILES = am__vpath_adj_setup = srcdirstrip=`echo "$(srcdir)" | sed 's|.|.|g'`; am__vpath_adj = case $$p in \ $(srcdir)/*) f=`echo "$$p" | sed "s|^$$srcdirstrip/||"`;; \ *) f=$$p;; \ esac; am__strip_dir = f=`echo $$p | sed -e 's|^.*/||'`; am__install_max = 40 am__nobase_strip_setup = \ srcdirstrip=`echo "$(srcdir)" | sed 's/[].[^$$\\*|]/\\\\&/g'` am__nobase_strip = \ for p in $$list; do echo "$$p"; done | sed -e "s|$$srcdirstrip/||" am__nobase_list = $(am__nobase_strip_setup); \ for p in $$list; do echo "$$p $$p"; done | \ sed "s| $$srcdirstrip/| |;"' / .*\//!s/ .*/ ./; s,\( .*\)/[^/]*$$,\1,' | \ $(AWK) 'BEGIN { files["."] = "" } { files[$$2] = files[$$2] " " $$1; \ if (++n[$$2] == $(am__install_max)) \ { print $$2, files[$$2]; n[$$2] = 0; files[$$2] = "" } } \ END { for (dir in files) print dir, files[dir] }' am__base_list = \ sed '$$!N;$$!N;$$!N;$$!N;$$!N;$$!N;$$!N;s/\n/ /g' | \ sed '$$!N;$$!N;$$!N;$$!N;s/\n/ /g' am__uninstall_files_from_dir = { \ test -z "$$files" \ || { test !

mmtaghostname.c * This is a message modification module. * * The name of the module is inspired by the parser module pmnull * Its objectives are closed to this parser but as a message modification * it can be used in a different step of the message processing without * interfering in the parser chain process and can be applied before or * after parsing process. * * Its purposes are : * - to add a tag on message produce by input module which does not provide * a tag like imudp or imtcp. Useful when the tag is used for routing the * message. * - to force message hostname to the rsyslog valeur. The use case is * application in auto-scaling systems (AWS) providing logs through udp/tcp * were the name of the host is based on an ephemeral IPs with a short term * meaning. In this situation rsyslog local host name is generally the * auto-scaling name then logs produced by the application is affected to * the application instead of the ephemeral VM. * * * This file is a contribution of rsyslog. * * Author : Ph.

It offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output to the results to diverse destinations. Rsyslog can deliver over one million messages per second to local destinations when limited processing is applied (based on v7, December 2013). Even with remote destinations and more elaborate processing the performance is usually considered "stunning". Mailing List ============ http://lists.adiscon.net/mailman/listinfo/rsyslog Installing rsyslog ================== Most distributions carry rsyslog in their repository. So you usually just need to use the package manager to install it. Note that on non-systemd systems (most notably Ubuntu), rsyslog usually is already installed. Project-Provided Packages ---------------------------- Unfortunately, distributions often do not catch up with the pace of rsyslog development and as such only offer old versions. To solve that problem, we have created packages for current versions ourselves. They are available for: * RPM-based systems: https://www.rsyslog.com/rhelcentos-rpms/ * Ubuntu: https://www.rsyslog.com/ubuntu-repository/ * Debian: https://www.rsyslog.com/debian-repository/ Building from Source -------------------- Follow the instructions at: https://www.rsyslog.com/doc/v8-stable/installation/build_from_repo.html ### Build Environment In general, you need * pkg-config * libestr * liblogging (stdlog component, for testbench) It is best to build these from source. #### CentOS 6 / RHEL For json-c, we need: ``` export PKG_CONFIG_PATH=/lib64/pkgconfig/ ``` ``` sudo yum install git valgrind autoconf automake flex bison python-docutils python-sphinx json-c-devel libuuid-devel libgcrypt-devel zlib-devel openssl-devel libcurl-devel gnutls-devel mysql-devel postgresql-devel libdbi-dbd-mysql libdbi-devel net-snmp-devel ``` #### Ubuntu Add Adiscon repository: ``` apt-get update && apt-get install -y software-properties-common add-apt-repository -y ppa:adiscon/v8-stable ``` *Note:* if you are a developer who wants to work with git master branch, adding the Adiscon repository is probably not a good idea. It then is better to also compile the supporting libraries from source, because newer versions of rsyslog may need newer versions of the libraries than there are in the repositories. Libraries in question are at least: libestr, liblognorm, libfastjson. Needed packages to build with omhiredis support: ``` apt-get update && apt-get install -y build-essential pkg-config libestr-dev libfastjson-dev zlib1g-dev uuid-dev libgcrypt20-dev libhiredis-dev uuid-dev libgcrypt11-dev liblogging-stdlog-dev flex bison ``` Aditional packages for other modules: ``` libdbi-dev libmysqlclient-dev postgresql-client libpq-dev libnet-dev librdkafka-dev libgrok-dev libgrok1 libgrok-dev libpcre3-dev libtokyocabinet-dev libglib2.0-dev libmongo-client-dev ``` For KSI, from the Adiscon PPA: ``` sudo apt-get install libksi0 libksi-devel ``` #### Debian ``` sudo apt install build-essential pkg-config libestr-dev libfastjson-dev zlib1g-dev uuid-dev libgcrypt20-dev libcurl4-gnutls-dev zlib1g-dev liblogging-stdlog-dev flex bison ``` *Note:* For certain libraries version requirements might be higher, in that case adding debian backports repositories might help. For example installing with apt libfastjson-dev -t stretch-backports. Aditional packages for other modules: ``` libdbi-dev libmysqlclient-dev postgresql-client libpq-dev libnet-dev librdkafka-dev libgrok-dev libgrok1 libgrok-dev libpcre3-dev libtokyocabinet-dev libglib2.0-dev libmongo-client-dev ``` #### openSUSE 13 ``` sudo zypper install gcc make autoconf automake libtool libcurl-devel flex bison valgrind python-docutils libjson-devel uuid-devel libgcrypt-devel libgnutls-devel libmysqlclient-devel libdbi-devel libnet-devel postgresql-devel net-snmp-devellibuuid-devel libdbi-drivers-dbd-mysql ``` For the testbench VMs: ``` sudo zypper install gvim mutt ``` #### SUSE LINUX Enterprise Server 11 Available packages: ``` zypper install gcc make autoconf libtool flex bison ``` Missing packages: ``` libcurl-devel valgrind python-docutils uuid-devel libgcrypt-devel libgnutls-devel libmysqlclient-devel libdbi-devel postgresql-devel net-snmp-devel libdbi-drivers-dbd-mysql json-c zlib-dev libdbi ``` Reporting Bugs ============== Talk to the mailing list if you think something is a bug. Often, it's just a matter of doing some config trickery. File bugs at: https://github.com/rsyslog/rsyslog/issues How to Contribute ================= Contributions to rsyslog are very welcome. Fork and send us your Pull Requests. For more information about contributing, see the [CONTRIBUTING](CONTRIBUTING.md) file. Note that it is easy to add output plugins using languages like Python or Perl. So if you need to connect to a system which is not yet supported, you can easily do so via an external plugin. For more information see the [README](plugins/external/README.md) file in the external plugin directory. Documentation ============= The main rsyslog documentation is available in HTML format. To read it, point your web browser to ./doc/manual.html. Alternatively, you can view the documentation for *the most recent rsyslog version* online at: https://www.rsyslog.com/doc/ Project Philosophy ================== We are an open source project in all aspects and very open to outside feedback and contribution. We base our work on standards and try to solve all real-world needs (of course, we occasionally fail tackling actually all needs ;)). While the project is primarily sponsored by Adiscon, technical development is independent from company goals and most decisions are solely based on mailing list discussion results. There is an active community around rsyslog. There is no such thing like being an official member of the rsyslog team. The closest to that is being subscribed to the mailing list: http://lists.adiscon.net/mailman/listinfo/rsyslog This method of open discussions is modelled after the IETF process, which is probably the best-known and most successive collaborative standards body. Project Funding =============== Rsyslog's main sponsor Adiscon tries to fund rsyslog by selling custom development and support contracts. Adiscon does NOT license rsyslog under a commercial license (this is simply impossible for anyone due to rsyslog's license structure). Any third party is obviously also free to offer custom development, support and rsyslog consulting. We gladly merge results of such third-party work into the main repository (assuming it matches the few essential things written down in our contribution policy). rsyslog-8.2412.0/parse.h0000664000175000017500000000722314650736301010431 /* parsing routines for the counted string class. These * 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. * * begun 2005-09-09 rgerhards * * Copyright (C) 2005-2012 Adiscon GmbH * * This file is part of rsyslog. * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * -or- * see COPYING.ASL20 in the source distribution * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #ifndef _PARSE_H_INCLUDED__ #define _PARSE_H_INCLUDED__ 1 #include "stringbuf.h" /** * The parse object */ struct rsParsObject { #ifndef NDEBUG rsObjID OID; /**< object ID */ #endif cstr_t *pCStr; /**< pointer to the string object we are parsing */ size_t iCurrPos; /**< current parsing position (char offset) */ }; typedef struct rsParsObject rsParsObj; /* BEGIN "inline"-like functions */ /* END "inline"-like functions */ int rsParsGetParsePointer(rsParsObj *pThis); /** * Construct a rsPars object. */ rsRetVal rsParsConstruct(rsParsObj **ppThis); rsRetVal rsParsAssignString(rsParsObj *pThis, cstr_t *pCStr); /* parse an integer.

Return the value in the variable # $ax_enable_compile_warnings. # # Depending on the value of --enable-compile-warnings, different compiler # warnings are checked to see if they work with the current compiler and, # if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This # allows a consistent set of baseline compiler warnings to be used across # a code base, irrespective of any warnings enabled locally by individual # developers. By standardising the warnings used by all developers of a # project, the project can commit to a zero-warnings policy, using -Werror # to prevent compilation if new warnings are introduced. This makes # catching bugs which are flagged by warnings a lot easier. # # By providing a consistent --enable-compile-warnings argument across all # projects using this macro, continuous integration systems can easily be # configured the same for all projects. Automated systems or build # systems aimed at beginners may want to pass the --disable-Werror # argument to unconditionally prevent warnings being fatal. # # --enable-compile-warnings can take the values: # # * no: Base compiler warnings only; not even -Wall. # * yes: The above, plus a broad range of useful warnings. # * error: The above, plus -Werror so that all warnings are fatal. # Use --disable-Werror to override this and disable fatal # warnings. # # The set of base and enabled flags can be augmented using the # EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and # appended to the output variable if --enable-compile-warnings is not # "no". Flags should not be disabled using these arguments, as the entire # point of AX_COMPILER_FLAGS is to enforce a consistent set of useful # compiler warnings on code, using warnings which have been chosen for low # false positive rates. If a compiler emits false positives for a # warning, a #pragma should be used in the code to disable the warning # locally. See: # # https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas # # The EXTRA-* variables should only be used to supply extra warning flags, # and not general purpose compiler flags, as they are controlled by # configure options such as --disable-Werror. # # IS-RELEASE can be used to disable -Werror when making a release, which # is useful for those hairy moments when you just want to get the release # done as quickly as possible. Set it to "yes" to disable -Werror. By # default, it uses the value of $ax_is_release, so if you are using the # AX_IS_RELEASE macro, there is no need to pass this parameter. For # example: # # AX_IS_RELEASE([git-directory]) # AX_COMPILER_FLAGS() # # CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults # to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must # be manually added to the CFLAGS and LDFLAGS variables for each target in # the code base. # # If C++ language support is enabled with AC_PROG_CXX, which must occur # before this macro in configure.ac, warning flags for the C++ compiler # are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the # CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can # be used to augment the base and enabled flags. # # Warning flags for g-ir-scanner (from GObject Introspection) are # AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added # to the SCANNERFLAGS variable for each GIR target in the code base. If # extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR # macro must be invoked manually. # # AX_COMPILER_FLAGS may add support for other tools in future, in addition # to the compiler and linker. No extra EXTRA-* variables will be added # for those tools, and all extra support will still use the single # --enable-compile-warnings configure option. For finer grained control # over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS, # AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools. # # The UNUSED variables date from a previous version of this macro, and are # automatically appended to the preceding non-UNUSED variable.

By contributing, you help improve the state of logging as well as improve your own professional profile. Contributing is easy, and there are options for everyone - you do not need to be a developer. These are many ways to contribute to the project: * become a rsyslog ambassador and let other people know about rsyslog and how to utilize it for best results. Help rsyslog getting backlinks, be present on Internet news sites or at meetings you attend. * help others by offering support on * the rsyslog's github home at https://github.com/rsyslog/rsyslog * the rsyslog mailing list at http://lists.adiscon.net/mailman/listinfo/rsyslog * help with the documentation; you can either contribute * to the [rsyslog doc directory](https://github.com/rsyslog/rsyslog-doc), which is shown on http://rsyslog.com/doc * to the rsyslog project web site -- just ask us for account creation * become a bug-hunter and help with testing rsyslog development releases * help driving the rsyslog infrastructure with its web sites and the like * help creating packages * or, obviously, help with rsyslog code development This list is not conclusive. There for sure are many more ways to contribute and if you find one, just let us know. We are very open to new suggestions and like to try out new things. ## When to submit Pull Requests? It is OK to submit PRs that are not yet fully ready for merging. You want to do this in order to get early CI system coverage for your patch. However, all patches should be reasonably complete and "work" in a sense. If you submit such PRs, please flag them as "work in progress" by adding "WiP:" in front of the title. We will NOT merge these PRs before you tell us they are now ready for merging. If you just want/need to do a temporary experiment, you may open a PR, flag it as "EXPERIMENT - DO NOT MERGE", let the CI tests run, check results and close the PR thereafter. This prevents unnecessary cluttering of the open PR list. We will take the liberty to close such PRs if they are left open for an extended period of time. Please note, though, that the rsyslog repo is fully set up to use Travis CI. Travis covers about 95% of all essential testing. So we highly recommend that you use Travis to do initial checks on your work and create the PR only after this looks good. That saves both you and us some time. ## Requirements for patches In order to ensure good code quality, after applying the path the code must - no legacy configuration statements ($someSetting) must be added, all configuration must be in v6+ style (RainerScript) - compile cleanly without WARNING messages under both gcc and clang - pass clang static analyzer without any report - pass all CI tests - new functionality must have associated * testbench tests * doc additions in the rsyslog-doc sister project - be [sufficiently squashed](https://rainer.gerhards.net/2019/03/squash-your-pull-requests.html) ### Testbench Coverage If you fix a bug that is not detected by the current testbench, it is appreciated if you also add testbench test to make sure the problem does not re-occur in the future. In contrast to new feature PRs, this is not a hard requirement, but it helps to speed up merging. If there is no testbench test added, the core rsyslog developers will try to add one based on the patch. That means merging needs to wait until we have time to do this. ### Compiler Diagnostics Note that both warning messages and static analyzer warnings may be false positives. We have decided to accept that fate and work around it (e.g. by re-arranging the code, etc). Otherwise, we cannot use these useful features. As a last resort, compiler warnings can be turned off via #pragma diagnostic directives. This should really only be done if there is no other known way around it. If so, it should be applied to a single function, only and not to full source file. Be sure to re-enable the warning after the function in question. We have done this in some few cases ourselves, and if someone can fix the root cause, we would appreciate help. But, again, this is a last resort which should normally not be used. Please read [on the importance of static analysis and why we request you to work around false positives](https://rainer.gerhards.net/2018/06/why-static-code-analysis.html). ### Continuous Integration Testing All patches are run though our continuous integration system, which ensures no regressions are inside the code as well as rsyslog project policies are followed (as far as we can check in an automated way). For pull requests submitted via github, these two conditions are verified automatically. See the PR for potential failures. For patches submitted otherwise, they will be verified semi-manually. Also, patches are requested to not break the testbench. Unfortunately, the current testbench has some racy tests, which are still useful enough so that we do not want to disable them until the root cause has been found. If your PR runs into something that you think is not related to your code, just sit back and relax. The rsyslog core developer team reviews PRs regularly and restarts tests which we know to look racy. If the problem persists, we will contact you. All PRs will be tested on a variety of systems, with the help of both Travis CI and buildbot. The core goal of this multi-platform testing is to find issues that surface only on some systems (e.g. 32bit related issues, etc). We continuously strive to update the CI system coverage. If you can provide a buildbot slave for a not-yet-supported test platform, please let us know. We will gladly add it. Note that test coverage differs between platforms. For example, not all databases etc. are tested on each platform. Also note that due to resource constraints some very lengthy tests are only execute on some (maybe only a single) platform. Note that we always try to merge with the most recent master branch and try a build from that version (if automatic merging is possible). If this test fails but no other, chances are good that there is an inter-PR issue. If this happens, it is suggested to rebase to git master branch and update the PR. ## Note to developers Please address pull requests against the master branch. ## Testbench coding Tips - look for similar tests and use them as copy template. Be sure to update comments as well. - see ./tests/diag.sh -- this is the base testing framework and it contains many functions you can use inside your tests - keep test cases simple and focussed on one topic. Otherwise it is hard to address test failures when they happen in the future. ------------------------------------------------------------------------------------- LEGAL GDPR NOTICE: According to the European data protection laws (GDPR), we would like to make you aware that contributing to rsyslog via git will permanently store the name and email address you provide as well as the actual commit and the time and date you made it inside git's version history. This is inevitable, because it is a main feature git. If you are concerned about your privacy, we strongly recommend to use --author "anonymous " together with your commit. Also please do NOT sign your commit in this case, as that potentially could lead back to you. Please note that if you use your real identity, the GDPR grants you the right to have this information removed later. However, we have valid reasons why we cannot remove that information later on. The reasons are: * this would break git history and make future merges unworkable * the rsyslog projects has legitimate interest to keep a permanent record of the contributor identity, once given, for - copyright verification - being able to provide proof should a malicious commit be made Please also note that your commit is public and as such will potentially be processed by many third-parties. Git's distributed nature makes it impossible to track where exactly your commit, and thus your personal data, will be stored and be processed.

It is slowly 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. Test Naming =========== Test that use valgrind shall end in "-vg.sh". Test that use valgrind's helgrind thread debugger shall end in "-vgthread.sh". Setting up Test Environments ============================ Setting up MariaDB/MySQL ------------------------ to create the necessary user: echo "create user 'rsyslog'@'localhost' identified by 'testbench';" | mysql -u root mysql -u root < ../plugins/ommysql/createDB.sql echo "grant all on Syslog.* to 'rsyslog'@'localhost';" | mysql -u root openSUSE -------- To configure system properties like hostname and firewall, use the graphical "yast2" administration tool. Note the ssh-access by default is disable in the firewall! Before running tests ==================== make check - this will compile all of the C code used in the tests, as well as do any other preparations, and will start running all of the tests. Ctrl-C to stop running all of the tests. Running all tests ================= make check Running named tests =================== make testname.log For example, to run the imfile-basic.sh test, use make imfile-basic.log Test output is in imfile-basic.log To re-run the test, first remove imfile-basic.log then make again Or an alternative option is to run make check TESTS='imfile-basic.sh' * Using gdb to debug rsyslog during a test run Edit your test like this: . $srcdir/diag.sh startup if [ -n "${USE_GDB:-}" ] ; then echo attach gdb here sleep 54321 || : fi Run your test in the background: USE_GDB=1 make mytest.sh.log & Tail mytest.sh.log until you see 'attach gdb here'. The log should also tell you what is the rsyslogd pid. gdb ../tools/rsyslogd $rsyslogd_pid Set breakpoints, whatever, then 'continue' In another window, do ps -ef|grep 54321, then kill that pid Core Dump Analysis ================== The testbench contains some limited (yet useful) support for automatically analyzing core dumps. In order for this to work, obviously core files need to be generated. This often doesn't work as intended. If you hit this problem, check 1. ulimit -c unlimited (or a reasonable limit) Note that root may need to increase a system-wide limit, which is usually recorded in /etc/security/limits.conf You need: * soft core unlimited 2. cat /proc/sys/kernel/core_pattern" On systemd systems (and some others), the pattern is changed to save core files so that systemd can import them -- with the result that the testbench doesn't see them any longer. We require classic format, which can be set via $ sudo bash -c "echo \"core\" > /proc/sys/kernel/core_pattern" Note that you probably want to do neither of these changes to a production system. rsyslog-8.2412.0/tests/override_gethostname_nonfqdn.c0000664000175000017500000000035414650736301016412 #include int gethostname(char *name, size_t __attribute__((unused)) len) { *name++ = 'n'; *name++ = 'o'; *name++ = 'n'; *name++ = 'f'; *name++ = 'q'; *name++ = 'd'; *name++ = 'n'; *name++ = '\0'; return 0; } rsyslog-8.2412.0/tests/imfile-error-not-repeated.sh0000775000175000017500000000255014650736301015626 #!/bin/bash # add 2017-04-28 by Pascal Withopf, released under ASL 2.0 . ${srcdir:=.}/diag.sh init generate_conf add_conf ' module(load="../plugins/imfile/.libs/imfile" mode="polling" pollingInterval="1") input(type="imfile" File="./'$RSYSLOG_DYNNAME'.input" Tag="tag1" ruleset="ruleset1") template(name="tmpl1" type="string" string="%msg%\n") ruleset(name="ruleset1") { action(type="omfile" file=`echo $RSYSLOG_OUT_LOG` template="tmpl1") } action(type="omfile" file=`echo $RSYSLOG2_OUT_LOG`) ' startup ./msleep 3000 echo 'testmessage1 testmessage2 testmessage3' > $RSYSLOG_DYNNAME.input ./msleep 2000 rm ./'$RSYSLOG_DYNNAME'.input ./msleep 3000 shutdown_when_empty wait_shutdown grep "file.*$RSYSLOG_DYNNAME.input.*No such file or directory" ${RSYSLOG2_OUT_LOG} > /dev/null if [ $? -ne 0 ]; then echo "FAIL: expected error message from missing input file not found. ${RSYSLOG2_OUT_LOG} is:" cat ${RSYSLOG2_OUT_LOG} error_exit 1 fi if [ $(grep "No such file or directory" ${RSYSLOG2_OUT_LOG} | wc -l) -ne 1 ]; then echo "FAIL: expected error message is put out multiple times. ${RSYSLOG2_OUT_LOG} is:" cat ${RSYSLOG2_OUT_LOG} error_exit 1 fi echo 'testmessage1 testmessage2 testmessage3' | cmp - $RSYSLOG_OUT_LOG if [ ! $? -eq 0 ]; then echo "invalid response generated, $RSYSLOG_OUT_LOG is:" cat $RSYSLOG_OUT_LOG error_exit 1 fi; exit_test rsyslog-8.2412.0/tests/rscript_num2ipv4.sh0000775000175000017500000000270014650736301014074 #!/bin/bash # add 2017-02-09 by Jan Gerhards, released under ASL 2.0 . ${srcdir:=.}/diag.sh init generate_conf add_conf ' module(load="../plugins/imtcp/.libs/imtcp") module(load="../plugins/fmhttp/.libs/fmhttp") input(type="imtcp" port="0" listenPortFileName="'$RSYSLOG_DYNNAME'.tcpflood_port") set $!ip!v0 = num2ipv4(""); set $!ip!v1 = num2ipv4("0"); set $!ip!v2 = num2ipv4("1"); set $!ip!v3 = num2ipv4("256"); set $!ip!v4 = num2ipv4("65536"); set $!ip!v5 = num2ipv4("16777216"); set $!ip!v6 = num2ipv4("135"); set $!ip!v7 = num2ipv4("16843009"); set $!ip!v8 = num2ipv4("3777036554"); set $!ip!v9 = num2ipv4("2885681153"); set $!ip!v10 = num2ipv4("4294967295"); set $!ip!e1 = num2ipv4("a"); set $!ip!e2 = num2ipv4("-123"); set $!ip!e3 = num2ipv4("1725464567890"); set $!ip!e4 = num2ipv4("4294967296"); set $!ip!e5 = num2ipv4("2839."); template(name="outfmt" type="string" string="%!ip%\n") local4.* action(type="omfile" file=`echo $RSYSLOG_OUT_LOG` template="outfmt") ' startup tcpflood -m1 -y shutdown_when_empty wait_shutdown echo '{ "v0": "0.0.0.0", "v1": "0.0.0.0", "v2": "0.0.0.1", "v3": "0.0.1.0", "v4": "0.1.0.0", "v5": "1.0.0.0", "v6": "0.0.0.135", "v7": "1.1.1.1", "v8": "225.33.1.10", "v9": "172.0.0.1", "v10": "255.255.255.255", "e1": "-1", "e2": "-1", "e3": "-1", "e4": "-1", "e5": "-1" }' | cmp - $RSYSLOG_OUT_LOG if [ ! $? -eq 0 ]; then echo "invalid function output detected, $RSYSLOG_OUT_LOG is:" cat $RSYSLOG_OUT_LOG error_exit 1 fi; exit_test rsyslog-8.2412.0/tests/diskqueue-full.sh0000775000175000017500000000150114650736301013577 #!/bin/bash # checks that nothing bad happens if a DA (disk) queue runs out # of configured disk space # addd 2017-02-07 by RGerhards, released under ASL 2.0 . ${srcdir:=.}/diag.sh init generate_conf add_conf ' module(load="../plugins/omtesting/.libs/omtesting") global(workDirectory="'${RSYSLOG_DYNNAME}'.spool") main_queue(queue.filename="mainq" queue.maxDiskSpace="4m" queue.maxfilesize="1m" queue.timeoutenqueue="300000" queue.lowwatermark="5000" ) template(name="outfmt" type="string" string="%msg:F,58:2%,%msg:F,58:3%,%msg:F,58:4%\n") :omtesting:sleep 0 5000 :msg, contains, "msgnum:" action(type="omfile" template="outfmt" file=`echo $RSYSLOG_OUT_LOG`) ' startup injectmsg 0 20000 ls -l ${RSYSLOG_DYNNAME}.spool shutdown_when_empty wait_shutdown ls -l ${RSYSLOG_DYNNAME}.spool seq_check 0 19999 exit_test rsyslog-8.2412.0/tests/randomgen.c0000664000175000017500000000651014650736301012424 /* generates random data for later use in test cases.
