This update for libseccomp fixes the following issues :
Security issues fixed :
libseccomp was updated to new upstream release 2.4.1 :
libseccomp was 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
