<p>An update that has four fixes can now be installed.</p>
<h2>Description:</h2>
<p>This update for libseccomp, python-Cython fixes the following issues:</p>
<p>python-Cython is included in version 0.29.14 to make libseccomp build.</p>
<p>Changes in libseccomp:</p>
<p>Update to release 2.5.3:</p>
<ul>
<li>Update the syscall table for Linux v5.15</li>
<li>Fix issues with multiplexed syscalls on mipsel introduced in v2.5.2</li>
<li>Document that seccomp_rule_add() may return -EACCES</li>
</ul>
<p>Update to release 2.5.2:</p>
<ul>
<li>Update the syscall table for Linux v5.14-rc7</li>
<li>Add a function, get_notify_fd(), to the Python bindings to
get the nofication file descriptor.</li>
<li>Consolidate multiplexed syscall handling for all
architectures into one location.</li>
<li>Add multiplexed syscall support to PPC and MIPS</li>
<li>The meaning of SECCOMP_IOCTL_NOTIF_ID_VALID changed within
the kernel. libseccomp's fd notification logic was modified
to support the kernel's previous and new usage of
SECCOMP_IOCTL_NOTIF_ID_VALID.</li>
</ul>
<p>Update to 2.5.1:</p>
<ul>
<li>Fix a bug where seccomp_load() could only be called once</li>
<li>Change the notification fd handling to only request a notification fd if</li>
<li>the filter has a _NOTIFY action</li>
<li>Add documentation about SCMP_ACT_NOTIFY to the seccomp_add_rule(3) manpage</li>
<li>Clarify the maintainers' GPG keys</li>
</ul>
<p>Update to release 2.5.0:</p>
<ul>
<li>Add support for the seccomp user notifications, see the
seccomp_notify_alloc(3), seccomp_notify_receive(3),
seccomp_notify_respond(3) manpages for more information</li>
<li>Add support for new filter optimization approaches, including a balanced
tree optimization, see the SCMP_FLTATR_CTL_OPTIMIZE filter attribute for
more information</li>
<li>Add support for the 64-bit RISC-V architecture</li>
<li>Performance improvements when adding new rules to a filter thanks to the
use of internal shadow transactions and improved syscall lookup tables (bsc#1209407)</li>
<li>Properly document the libseccomp API return values and include them in the
stable API promise</li>
<li>Improvements to the s390 and s390x multiplexed syscall handling</li>
<li>Multiple fixes and improvements to the libseccomp manpages</li>
<li>Moved from manually maintained syscall tables to an automatically generated
syscall table in CSV format</li>
<li>Update the syscall tables to Linux v5.8.0-rc5</li>
<li>Python bindings and build now default to Python 3.x</li>
<li>Improvements to the tests have boosted code coverage to over 93%</li>
</ul>
<p>Update to release 2.4.3:</p>
<ul>
<li>Add list of authorized release signatures to README.md</li>
<li>Fix multiplexing issue with s390/s390x shm* syscalls</li>
<li>Remove the static flag from libseccomp tools compilation</li>
<li>Add define for __SNR_ppoll</li>
<li>Fix potential memory leak identified by clang in the
scmp_bpf_sim tool</li>
