Description:

This update for libseccomp, python-Cython fixes the following issues:

python-Cython is included in version 0.29.14 to make libseccomp build.

Changes in libseccomp:

Update to release 2.5.3:

  • Update the syscall table for Linux v5.15
  • Fix issues with multiplexed syscalls on mipsel introduced in v2.5.2
  • Document that seccomp_rule_add() may return -EACCES

Update to release 2.5.2:

  • Update the syscall table for Linux v5.14-rc7
  • Add a function, get_notify_fd(), to the Python bindings to get the nofication file descriptor.
  • Consolidate multiplexed syscall handling for all architectures into one location.
  • Add multiplexed syscall support to PPC and MIPS
  • 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.

Update to 2.5.1:

  • Fix a bug where seccomp_load() could only be called once
  • Change the notification fd handling to only request a notification fd if
  • the filter has a _NOTIFY action
  • Add documentation about SCMP_ACT_NOTIFY to the seccomp_add_rule(3) manpage
  • Clarify the maintainers' GPG keys

Update to release 2.5.0:

  • 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
  • Add support for new filter optimization approaches, including a balanced tree optimization, see the SCMP_FLTATR_CTL_OPTIMIZE filter attribute for more information
  • Add support for the 64-bit RISC-V architecture
  • Performance improvements when adding new rules to a filter thanks to the use of internal shadow transactions and improved syscall lookup tables (bsc#1209407)
  • Properly document the libseccomp API return values and include them in the stable API promise
  • Improvements to the s390 and s390x multiplexed syscall handling
  • Multiple fixes and improvements to the libseccomp manpages
  • Moved from manually maintained syscall tables to an automatically generated syscall table in CSV format
  • Update the syscall tables to Linux v5.8.0-rc5
  • Python bindings and build now default to Python 3.x
  • Improvements to the tests have boosted code coverage to over 93%

Update to release 2.4.3:

  • Add list of authorized release signatures to README.md
  • Fix multiplexing issue with s390/s390x shm* syscalls
  • Remove the static flag from libseccomp tools compilation
  • Add define for __SNR_ppoll
  • Fix potential memory leak identified by clang in the scmp_bpf_sim tool

Update to release 2.4.2:

  • Add support for io-uring related system calls
