+ 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. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "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
+LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY 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
+LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.

+libseccomp: An Enhanced Seccomp (mode 2) Helper Library
+===============================================================================
+https://github.com/seccomp/libseccomp
+
+The libseccomp library provides an easy to use, platform independent, interface
+to the Linux Kernel's syscall filtering mechanism. 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.

+How to Submit Patches to the libseccomp Project
+===============================================================================
+https://github.com/seccomp/libseccomp
+
+This document is intended to act as a guide to help you contribute to the
+libseccomp project. 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 <random@developer.example.org>
+
+* 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.

+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+## dummy dependencies for each header file. Too bad gcc doesn't do
+## this for us directly.

+## ------ ##
+## Usage. ##
+## ------ ##
+
+# This file is a library for parsing options in your shell scripts along
+# with assorted other useful supporting features that you can make use
+# of too.
+#
+# For the simplest scripts you might need only:
+#
+# #!/bin/sh
+# . relative/path/to/funclib.sh
+# . relative/path/to/options-parser
+# scriptversion=1.0
+# func_options ${1+"$@"}
+# eval set dummy "$func_options_result"; shift
+# ...rest of your script...
+#
+# In order for the '--version' option to work, you will need to have a
+# suitably formatted comment like the one at the top of this file
+# starting with '# Written by ' and ending with '# warranty; '.
+#
+# For '-h' and '--help' to work, you will also need a one line
+# description of your script's purpose in a comment directly above the
+# '# Written by ' line, like the one at the top of this file.
+#
+# The default options also support '--debug', which will turn on shell
+# execution tracing (see the comment above debug_cmd below for another
+# use), and '--verbose' and the func_verbose function to allow your script
+# to display verbose messages only when your user has specified
+# '--verbose'.
+#
+# After sourcing this file, you can plug processing for additional
+# options by amending the variables from the 'Configuration' section
+# below, and following the instructions in the 'Option parsing'
+# section further down.
+
+## -------------- ##
+## Configuration. ##
+## -------------- ##
+
+# You should override these variables in your script after sourcing this
+# file so that they reflect the customisations you have added to the
+# option parser.
+
+# The usage line for option parsing errors and the start of '-h' and
+# '--help' output messages. You can embed shell variables for delayed
+# expansion at the time the message is displayed, but you will need to
+# quote other shell meta-characters carefully to prevent them being
+# expanded when the contents are evaled.
+usage='$progpath [OPTION]...'
+
+# Short help message in response to '-h' and '--help'. Add to this or
+# override it after sourcing this library to reflect the full set of
+# options your script accepts.
+usage_message="\
+ --debug enable verbose shell tracing
+ -W, --warnings=CATEGORY
+ report the warnings falling in CATEGORY [all]
+ -v, --verbose verbosely report processing
+ --version print version information and exit
+ -h, --help print short or long help message and exit
+"
+
+# Additional text appended to 'usage_message' in response to '--help'.
+long_help_message="
+Warning categories include:
+ 'all' show all warnings
+ 'none' turn off all the warnings

+\`configure' configures libseccomp 2.3.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]

+ --with-gnu-ld assume the C compiler uses GNU ld [default=no]
+ --with-sysroot[=DIR] Search for dependent libraries within DIR (or the
+ compiler's sysroot if not specified).
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ LT_SYS_LIBRARY_PATH
+ User-defined run-time library search path.
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.
+
+Report bugs to the package provider.

+.P
+This command resolves both system call names and numbers with respect to the
+given architecture supplied in the optional
+.I ARCH
+argument. If the architecture is not supplied on the command line then the
+native architecture is used. If the "\-t" argument is specified along with a
+system call name, then the system call will be translated as necessary for the
+given architecture. The "\-t" argument has no effect if a system call number
+is specified.
+.P
+In some combinations of architecture and system call, a negative system call
+number will be displayed. A negative system call number indicates that the
+system call is not defined for the given architecture and is treated in a
+special manner by libseccomp depending on the operation.
+.TP
+.B \-a \fIARCH
+The architecture to use for resolving the system call. Valid
+.I ARCH
+values are "x86", "x86_64", "x32", and "arm".

+If necessary, translate the system call name to the proper system call number,

+.P
+The

+function tests to see if a given architecture has been added to the seccomp
+filter in
+.I ctx
+, where the
+.BR seccomp_arch_add ()

+add and remove, respectively, architectures from the seccomp filter. In all
+three functions, the architecture values given in

+should be the

+defined constants; with the
+.BR SCMP_ARCH_NATIVE
+constant always referring to the native compiled architecture. The

+constants. While the
+.BR seccomp_arch_resolve_name ()
+function also returns a

+constant, the returned token matches the name of the architecture
+passed as an argument to the function.
+.P
+When a seccomp filter is initialized with the call to
+.BR seccomp_init (3)
+the native architecture is automatically added to the filter.
+.P
+While it is possible to remove all architectures from a filter, most of the

+.P
+The
+.BR seccomp_rule_add (),
+.BR seccomp_rule_add_array (),
+.BR seccomp_rule_add_exact (),
+and
+.BR seccomp_rule_add_exact_array ()
+functions all add a new filter rule to the current seccomp filter. The
+.BR seccomp_rule_add ()
+and
+.BR seccomp_rule_add_array ()
+functions will make a "best effort" to add the rule as specified, but may alter
+the rule slightly due to architecture specifics, e.g. socket and ipc functions
+on x86. The
+.BR seccomp_rule_add_exact ()
+and
+.BR seccomp_rule_add_exact_array ()
+functions will attempt to add the rule exactly as specified so it may behave
+differently on different architectures. While it does not guarantee a exact
+filter ruleset,
+.BR seccomp_rule_add ()
+and
+.BR seccomp_rule_add_array ()
+do guarantee the same behavior regardless of the architecture.
+.P
+The newly added filter rule does not take effect until the entire filter is
+loaded into the kernel using
+.BR seccomp_load (3).
+.P
+The
+.BR SCMP_CMP ()
+and
+.BR SCMP_A{0-5} ()
+macros generate a scmp_arg_cmp structure for use with the above functions. The
+.BR SCMP_CMP ()
+macro allows the caller to specify an arbitrary argument along with the
+comparison operator, mask, and datum values where the
+.BR SCMP_A{0-5} ()
+macros are specific to a certain argument. See the EXAMPLES section below.
+.P
+While it is possible to specify the
+.I syscall
+value directly using the standard
+.B __NR_syscall
+values, in order to ensure proper operation across multiple architectures it
+is highly recommended to use the
+.BR SCMP_SYS ()
+macro instead. 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,

+.sp
+SCMP_CMP(

+, SCMP_CMP_MASKED_EQ ,

+,

+libseccomp library. This function can be used by applications that need to
+verify that they are linked to a specific libseccomp version at runtime.
+.P
+The caller should not attempt to free the returned
+.B scmp_version
+struct when finished.
+.\" //////////////////////////////////////////////////////////////////////////
+.SH RETURN VALUE
+.\" //////////////////////////////////////////////////////////////////////////
+The
+.BR seccomp_version ()
+function returns a pointer to a
+.B scmp_version
+structure on success, NULL on failure. The caller should not attempt to free
+the returned structure.
+.\" //////////////////////////////////////////////////////////////////////////
+.SH EXAMPLES
+.\" //////////////////////////////////////////////////////////////////////////
+.nf
+#include <seccomp.h>
+
+int main(int argc, char *argv[])
+{
+ const struct scmp_version *ver;
+
+ ver = seccomp_version();
+ if (ver == NULL)

+.\" //////////////////////////////////////////////////////////////////////////
+.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. This tool,
+as well as the libseccomp library, is currently under development, please
+report any bugs at the project site or directly to the author.

+
+# These exist entirely to fool aclocal when bootstrapping libtool.
+#
+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else. This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
+# Yes, that means every name once taken will need to remain here until
+# we give up compatibility with versions before 1.7, at which point
+# we need to keep only those names which we still refer to.
+
+# This is to help aclocal find these macros, as it can't see m4_define.

+ * lookup3.c, by Bob Jenkins, May 2006, Public Domain.
+ *
+ * These are functions for producing 32-bit hashes for hash table lookup.
+ * jhash_word(), jhash_le(), jhash_be(), mix(), and final() are externally useful
+ * functions. 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.

+ * @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 ~^. For + and -, I transformed the
+ * output delta to a Gray code (a^(a>>1)) so a string of 1's (as is commonly
+ * produced by subtraction) look like a single 1-bit difference.
+ * - the base values were pseudorandom, all zero but one bit set, or all zero
+ * plus a counter that starts at zero.
+ *
+ * Some k values for my "a-=c; a^=rot(c,k); c+=b;" arrangement that
+ * satisfy this are
+ * 4 6 8 16 19 4
+ * 9 15 3 18 27 15

+ * Well, "9 15 3 18 27 15" didn't quite get 32 bits diffing for "differ"
+ * defined as + with a one-bit base and a two-bit delta. I used
+ * http://burtleburtle.net/bob/hash/avalanche.html to choose the operations,
+ * constants, and arrangements of the variables.
+ *
+ * This does not achieve avalanche. There are input bits of (a,b,c) that fail
+ * to affect some output bits of (a,b,c), especially of a. The most thoroughly
+ * mixed value is c, but it doesn't really even achieve avalanche in c.
+ *
+ * This allows some parallelism. Read-after-writes are good at doubling the
+ * number of bits affected, so the goal of mixing pulls in the opposite
+ * direction as the goal of parallelism. I did what I could. Rotates seem to
+ * cost as much as shifts on every machine I could lay my hands on, and rotates

+""" Python bindings for the libseccomp library
+
+The libseccomp library provides and easy to use, platform independent,
+interface to the Linux Kernel's syscall filtering mechanism: seccomp. 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.
+
+Filter action values:
+ KILL - kill the process
+ ALLOW - allow the syscall to execute
+ TRAP - a SIGSYS signal will be thrown
+ ERRNO(x) - syscall will return (x)
+ TRACE(x) - if the process is being traced, (x) will be returned to the
+ tracing process via PTRACE_EVENT_SECCOMP and the
+ PTRACE_GETEVENTMSG option
+
+Argument comparison values (see the Arg class):
+
+ NE - arg != datum_a
+ LT - arg < datum_a
+ LE - arg <= datum_a
+ EQ - arg == datum_a
+ GT - arg > datum_a
+ GE - arg >= datum_a
+ MASKED_EQ - (arg & datum_b) == datum_a
+
+
+Example:
+
+ import sys
+ from seccomp import *
+
+ # create a filter object with a default KILL action
+ f = SyscallFilter(defaction=KILL)
+
+ # add syscall filter rules to allow certain syscalls
+ f.add_rule(ALLOW, "open")
+ f.add_rule(ALLOW, "close")
+ f.add_rule(ALLOW, "read", Arg(0, EQ, sys.stdin))
+ f.add_rule(ALLOW, "write", Arg(0, EQ, sys.stdout))
+ f.add_rule(ALLOW, "write", Arg(0, EQ, sys.stderr))
+ f.add_rule(ALLOW, "rt_sigreturn")
+
+ # load the filter into the kernel
+ f.load()
