Routines to test the hash are included if SELF_TEST is defined. * You can use this free for any purpose. It's in the public domain. It has * no warranty. * * You probably want to use jhash_le(). jhash_le() and jhash_be() hash byte * arrays. jhash_le() is is faster than jhash_be() on little-endian machines. * Intel and AMD are little-endian machines. * * If you want to find a hash of, say, exactly 7 integers, do * a = i1; b = i2; c = i3; * mix(a,b,c); * a += i4; b += i5; c += i6; * mix(a,b,c); * a += i7; * final(a,b,c); * * then use c as the hash value. If you have a variable length array of * 4-byte integers to hash, use jhash_word(). If you have a byte array (like * a character string), use jhash_le(). If you have several byte arrays, or * a mix of things, see the comments above jhash_le(). * * Why is this so big? I read 12 bytes at a time into 3 4-byte integers, then * mix those integers. This is fast (you can do a lot more thorough mixing * with 12*3 instructions on 3 integers than you can with 3 instructions on 1 * byte), but shoehorning those bytes into integers efficiently is messy. */ #include #include "arch.h" #include "hash.h" #define hashsize(n) ((uint32_t)1<<(n)) #define hashmask(n) (hashsize(n)-1) #define rot(x,k) (((x)<<(k)) | ((x)>>(32-(k)))) /** * Mix 3 32-bit values reversibly * @param a 32-bit value * @param b 32-bit value * @param c 32-bit value * * This is reversible, so any information in (a,b,c) before mix() is still * in (a,b,c) after mix(). * * If four pairs of (a,b,c) inputs are run through mix(), or through mix() in * reverse, there are at least 32 bits of the output that are sometimes the * same for one pair and different for another pair. * * This was tested for: * - pairs that differed by one bit, by two bits, in any combination of top * bits of (a,b,c), or in any combination of bottom bits of (a,b,c). * - "differ" is defined as +, -, ^, or ~^.

The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional function-call based filtering interface that should be familiar to, and easily adopted by, application developers. * Online Resources The library source repository currently lives on GitHub at the following URL: -> https://github.com/seccomp/libseccomp The project mailing list is currently hosted on Google Groups at the URL below, please note that a Google account is not required to subscribe to the mailing list. -> https://groups.google.com/forum/#!forum/libseccomp -> https://groups.google.com/forum/#!forum/libseccomp/join * Documentation The "doc/" directory contains all of the currently available documentation, mostly in the form of manpages. The top level directory also contains a README file (this file) as well as the LICENSE, CREDITS, SUBMITTING_PATCHES, and CHANGELOG files. Those who are interested in contributing to the the project are encouraged to read the SUBMITTING_PATCHES in the top level directory. * Building and Installing the Library If you are building the libseccomp library from an official release tarball, you should follow the familiar three step process used by most autotools based applications: # ./configure # make [V=0|1] # make install However, if you are building the library from sources retrieved from the source repository you may need to run the autogen.sh script before running configure. In both cases, running "./configure -h" will display a list of build-time configuration options. * Testing the Library There are a number of tests located in the "tests/" directory and a make target which can be used to help automate their execution. If you want to run the standard regression tests you can execute the following after building the library: # make check Be warned that the test run can take a while to run and produces a lot of output. * Other Useful Tools The "tools/" directory includes a number of tools which may be helpful in the development of the library, or applications using the library. Not all of these tools are installed by default. libseccomp-2.3.1/PaxHeaders.9120/LICENSE0000644000000000000000000000013111740660643014320 xustar0030 mtime=1334010275.310185534 30 atime=1345129808.384386886 29 ctime=1461183071.74821117 libseccomp-2.3.1/LICENSE0000644000175000001440000005755411740660643015411 0ustar00pmooreusers00000000000000 GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, 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 this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. 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 not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), 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 distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the 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 specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15.

See the EXAMPLES section below. .P The filter context .I ctx is the value returned by the call to .BR seccomp_init (3). .P Valid .I action values are as follows: .TP .B SCMP_ACT_KILL The thread will be killed by the kernel when it calls a syscall that does not match any of the configured seccomp filter rules. .TP .B SCMP_ACT_TRAP The thread will throw a SIGSYS signal when it calls a syscall that does not match any of the configured seccomp filter rules. .TP .B SCMP_ACT_ERRNO(uint16_t errno) The thread will receive a return value of .I errno when it calls a syscall that does not match any of the configured seccomp filter rules. .TP .B SCMP_ACT_TRACE(uint16_t msg_num) If the thread is being traced and the tracing process specified the .B PTRACE_O_TRACESECCOMP option in the call to .BR ptrace (2), the tracing process will be notified, via .B PTRACE_EVENT_SECCOMP , and the value provided in .I msg_num can be retrieved using the .B PTRACE_GETEVENTMSG option. .TP .B SCMP_ACT_ALLOW The seccomp filter will have no effect on the thread calling the syscall if it does not match any of the configured seccomp filter rules. .P Valid comparison .I op values are as follows: .TP .B SCMP_CMP_NE Matches when the argument value is not equal to the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_NE , .I datum ) .TP .B SCMP_CMP_LT Matches when the argument value is less than the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_LT , .I datum ) .TP .B SCMP_CMP_LE Matches when the argument value is less than or equal to the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_LE , .I datum ) .TP .B SCMP_CMP_EQ Matches when the argument value is equal to the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_EQ , .I datum ) .TP .B SCMP_CMP_GE Matches when the argument value is greater than or equal to the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_GE , .I datum ) .TP .B SCMP_CMP_GT Matches when the argument value is greater than the datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_GT , .I datum ) .TP .B SCMP_CMP_MASKED_EQ Matches when the masked argument value is equal to the masked datum value, example: .sp SCMP_CMP( .I arg , SCMP_CMP_MASKED_EQ , .I mask , .I datum ) .\" ////////////////////////////////////////////////////////////////////////// .SH RETURN VALUE .\" ////////////////////////////////////////////////////////////////////////// The .BR seccomp_rule_add (), .BR seccomp_rule_add_array (), .BR seccomp_rule_add_exact (), and .BR seccomp_rule_add_exact_array () functions return zero on success, negative errno values on failure. .\" ////////////////////////////////////////////////////////////////////////// .SH EXAMPLES .\" ////////////////////////////////////////////////////////////////////////// .nf #include #include #include #include #define BUF_SIZE 256 int main(int argc, char *argv[]) { int rc = \-1; scmp_filter_ctx ctx; struct scmp_arg_cmp arg_cmp[] = { SCMP_A0(SCMP_CMP_EQ, 2) }; int fd; unsigned char buf[BUF_SIZE]; ctx = seccomp_init(SCMP_ACT_KILL); if (ctx == NULL) goto out; /* ... */ fd = open("file.txt", 0); /* ... */ rc = seccomp_rule_add(ctx, SCMP_ACT_ALLOW, SCMP_SYS(close), 0); if (rc < 0) goto out; rc = seccomp_rule_add(ctx, SCMP_ACT_ALLOW, SCMP_SYS(read), 3, SCMP_A0(SCMP_CMP_EQ, fd), SCMP_A1(SCMP_CMP_EQ, (scmp_datum_t)buf), SCMP_A2(SCMP_CMP_LE, BUF_SIZE)); if (rc < 0) goto out; rc = seccomp_rule_add(ctx, SCMP_ACT_ALLOW, SCMP_SYS(write), 1, SCMP_CMP(0, SCMP_CMP_EQ, fd)); if (rc < 0) goto out; rc = seccomp_rule_add_array(ctx, SCMP_ACT_ALLOW, SCMP_SYS(write), 1, arg_cmp); if (rc < 0) goto out; rc = seccomp_load(ctx); if (rc < 0) goto out; /* ... */ out: seccomp_release(ctx); return \-rc; } .fi .\" ////////////////////////////////////////////////////////////////////////// .SH NOTES .\" ////////////////////////////////////////////////////////////////////////// .P While the seccomp filter can be generated independent of the kernel, kernel support is required to load and enforce the seccomp filter generated by libseccomp. .P The libseccomp project site, with more information and the source code repository, can be found at https://github.com/seccomp/libseccomp.

It is not perfect, and there will always be exceptions to the rules described here, but by following the instructions below you should have a much easier time getting your work merged with the upstream project. * Test Your Code There are three possible tests you can run to verify your code. The first test is used to check the formatting and coding style of your changes, you can run the test with the following command: # make check-syntax ... if there are any problems with your changes a diff/patch will be shown which indicates the problems and how to fix them. The second possible test is used to ensure that the different internal syscall tables are consistent and to test your changes against the automated test suite. You can run the test with the following command: # make check ... if there are any faults or errors they will be displayed; beware that the tests can run for some time and produce a lot of output. The third possible test is used to validate libseccomp against a live, running system using some simple regression tests. After ensuring that your system supports seccomp filters you can run the live tests with the following command: # make check-build # cd tests # ./regression -T live ... if there are any faults or errors they will be displayed. * Generate the Patch(es) Depending on how you decided to work with the libseccomp code base and what tools you are using there are different ways to generate your patch(es). However, regardless of what tools you use, you should always generate your patches using the "unified" diff/patch format and the patches should always apply to the libseccomp source tree using the following command from the top directory of the libseccomp sources: # patch -p1 < changes.patch If you are not using git, stacked git (stgit), or some other tool which can generate patch files for you automatically, you may find the following command helpful in generating patches, where "libseccomp.orig/" is the unmodified source code directory and "libseccomp/" is the source code directory with your changes: # diff -purN libseccomp.orig/ libseccomp/ When in doubt please generate your patch and try applying it to an unmodified copy of the libseccomp sources; if it fails for you, it will fail for the rest of us. * Explain Your Work At the top of every patch you should include a description of the problem you are trying to solve, how you solved it, and why you chose the solution you implemented. If you are submitting a bug fix, it is also incredibly helpful if you can describe/include a reproducer for the problem in the description as well as instructions on how to test for the bug and verify that it has been fixed. * Sign Your Work The sign-off is a simple line at the end of the patch description, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The "Developer's Certificate of Origin" pledge is taken from the Linux Kernel and the rules are pretty simple: Developer's Certificate of Origin 1.1 By making a contribution to this project, I certify that: (a) The contribution was created in whole or in part by me and I have the right to submit it under the open source license indicated in the file; or (b) The contribution is based upon previous work that, to the best of my knowledge, is covered under an appropriate open source license and I have the right under that license to submit that work with modifications, whether created in whole or in part by me, under the same open source license (unless I am permitted to submit under a different license), as indicated in the file; or (c) The contribution was provided directly to me by some other person who certified (a), (b) or (c) and I have not modified it. (d) I understand and agree that this project and the contribution are public and that a record of the contribution (including all personal information I submit with it, including my sign-off) is maintained indefinitely and may be redistributed consistent with this project or the open source license(s) involved. ... then you just add a line to the bottom of your patch description, with your real name, saying: Signed-off-by: Random J Developer * Email Your Patch(es) Finally, you will need to email your patches to the mailing list so they can be reviewed and potentially merged into the main libseccomp repository. When sending patches to the mailing list it is important to send your email in text form, no HTML mail please, and ensure that your email client does not mangle your patches. It should be possible to save your raw email to disk and apply it directly to the libseccomp source code; if that fails then you likely have a problem with your email client. When in doubt try a test first by sending yourself an email with your patch and attempting to apply the emailed patch to the libseccomp repository; if it fails for you, it will fail for the rest of us trying to test your patch and include it in the main libseccomp repository. libseccomp-2.3.1/PaxHeaders.9120/CHANGELOG0000644000000000000000000000013112705760632014526 xustar0030 mtime=1461182874.036225968 30 atime=1461182874.036225968 29 ctime=1461183071.74721117 libseccomp-2.3.1/CHANGELOG0000644000175000001440000000763012705760632015605 0ustar00pmooreusers00000000000000libseccomp: Releases =============================================================================== https://github.com/seccomp/libseccomp * Version 2.3.1 - April 20, 2016 - Fixed a problem with 32-bit x86 socket syscalls on some systems - Fixed problems with ipc syscalls on 32-bit x86 - Fixed problems with socket and ipc syscalls on s390 and s390x * Version 2.3.0 - February 29, 2016 - Added support for the s390 and s390x architectures - Added support for the ppc, ppc64, and ppc64le architectures - Update the internal syscall tables to match the Linux 4.5-rcX releases - Filter generation for both multiplexed and direct socket syscalls on x86 - Support for the musl libc implementation - Additions to the API to enable runtime version checking of the library - Enable the use of seccomp() instead of prctl() on supported systems - Added additional tests to the regression test suite * Version 2.2.3 - July 8, 2015 - Fix a problem with 'make check' on 32-bit ARM systems * Version 2.2.2 - July 6, 2015 - Fix a problem with the masked equality operator - Fix a problem on x86_64/x32 involving invalid architectures - Fix a problem with the ARM specific syscalls - Fix a build problem when the source and build directories differ * Version 2.2.1 - May 13, 2015 - Fix a problem with syscall argument filtering on 64-bit systems - Fix some problems with the 32-bit ARM syscall table - Fix build problems on very old systems - Update the README file with the GitHub and Google Groups information * Version 2.2.0 - February 12, 2015 - Migrated the build system to autotools - Added support for the aarch64 architecture - Added support for the mips, mips64, and mips64n32 architectures for both big and little endian systems - Added support for using the new seccomp() syscall and the thread sync functionality - Added Python bindings - Updated the internal syscall tables to Linux v3.19 - Added documentation to help contributors wishing to submit patches - Migrated to GitHub for git hosting and Google Groups for the mailing list - Numerous minor bug fixes * Version 2.1.1 - October 31, 2013 - Build system improvements - Automated test improvements, including a "check" target for use by packagers to verify the build - Numerous bug fixes related to the filter's internal rule database which affect those creating rules with syscall arguments - Introduced tools to verify the style/formatting of the code, including a "check-syntax" target for use by developers - Non-public symbols are now hidden in the library * Version 2.1.0 - June 11, 2013 - Add support for the x32 and ARM architectures - Improvements to the regression tests, including support for live tests - More verbose PFC output, including translation of syscall numbers to names - Several assorted bugfixes affecting the seccomp BPF generation - The syscall number/name resolver tool is now available to install * Version 2.0.0 - January 28, 2013 - Fixes for the x86 multiplexed syscalls - Additions to the API to better support non-native architectures - Additions to the API to support multiple architectures in one filter - Additions to the API to resolve syscall name/number mappings - Assorted minor bug fixes - Improved build messages regardless of build verbosity - More automated tests added as well as a number of improvements to the test harness * Version 1.0.1 - November 12, 2012 - The header file is now easier to use with C++ compilers - Minor documentation fixes - Minor memory leak fixes - Corrected x86 filter generation on x86_64 systems - Corrected problems with small filters and filters with arguments * Version 1.0.0 - July 31, 2012 - Change the API to be context-aware;
