  Security issues fixed:

  - CVE-2019-9893: An incorrect generation of syscall filters in libseccomp
  was fixed (bsc#1128828)

  libseccomp was updated to new upstream release 2.4.1:

  - Fix a BPF generation bug where the optimizer mistakenly identified
  duplicate BPF code blocks.

  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

  libseccomp was updated to release 2.3.3:

  - Updated the syscall table for Linux v4.15-rc7


  This update was imported from the SUSE:SLE-15:Update update project.
