  script_tag(name:"insight", value:"This update for libseccomp fixes the following issues:

Update to new upstream release 2.4.1:
Fix a BPF generation bug where the optimizer mistakenly identified
 duplicate BPF code blocks.

Updated to 2.4.0 (bsc#1128828 CVE-2019-9893):
Update the syscall table for Linux v5.0-rc5

Added support for the SCMP_ACT_KILL_PROCESS action

Added support for the SCMP_ACT_LOG action and SCMP_FLTATR_CTL_LOG
 attribute

Added explicit 32-bit (SCMP_AX_32(...)) and 64-bit (SCMP_AX_64(...))
 argument comparison macros to help protect against unexpected sign
 extension

Added support for the parisc and parisc64 architectures

Added the ability to query and set the libseccomp API level via
 seccomp_api_get(3) and seccomp_api_set(3)

Return -EDOM on an endian mismatch when adding an architecture to a
 filter

Renumber the pseudo syscall number for subpage_prot() so it no longer
 conflicts with spu_run()

Fix PFC generation when a syscall is prioritized, but no rule exists

Numerous fixes to the seccomp-bpf filter generation code

Switch our internal hashing function to jhash/Lookup3 to MurmurHash3

Numerous tests added to the included test suite, coverage now at ~92%

Update our Travis CI configuration to use Ubuntu 16.04

Numerous documentation fixes and updates

Update to release 2.3.3:
Updated the syscall table for Linux v4.15-rc7

Update to release 2.3.2:
Achieved full compliance with the CII Best Practices program

Added Travis CI builds to the GitHub repository

Added code coverage reporting with the '--enable-code-coverage'
 configure flag and added Coveralls to the GitHub repository

Updated the syscall tables to match Linux v4.10-rc6+

Support for building with Python v3.x

Allow rules with the -1 syscall if the SCMP\_FLTATR\_API\_TSKIP
 attribute is set to true

Several small documentation fixes ignore make check error for ppc64/ppc64le, bypass bsc#1142614");
