description: |
  This kernel-linus update is based on the upstream 4.14.18 and and adds some
  support for mitigating  Spectre, variant 1 (CVE-2017-5753) and as it is
  built with the retpoline-aware gcc-5.5.0-1.mga6, it now provides full
  retpoline mitigation for Spectre, variant 2 (CVE-2017-5715).

  The BPF interpreter has been used as part of the spectre 2 attack
  CVE-2017-5715. To make attacker job harder introduce BPF_JIT_ALWAYS_ON
  config option that removes interpreter from the kernel in favor of JIT-only
  mode. This is now enabled by default in Mageia kernels.

  Other security fixes in this update:

  Linux kernel version 3.3-rc1 and later is affected by a vulnerability lies
  in the processing of incoming L2CAP commands - ConfigRequest, and
  ConfigResponse messages. This info leak is a result of uninitialized stack
  variables that may be returned to an attacker in their uninitialized state.
  By manipulating the code flows that precede the handling of these
  configuration messages, an attacker can also gain some control over which
  data will be held in the uninitialized stack variables. This can allow him
  to bypass KASLR, and stack canaries protection - as both pointers and stack
  canaries may be leaked in this manner (CVE-2017-1000410).

  A use-after-free vulnerability was found in network namespaces code
  affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id()
  in net/core/net_namespace.c does not check for the net::count value after
  it has found a peer network in netns_ids idr, which could lead to double
  free and memory corruption. This vulnerability could allow an unprivileged
  local user to induce kernel memory corruption on the system, leading to a
  crash. Due to the nature of the flaw, privilege escalation cannot be fully
  ruled out, although it is thought to be unlikely (CVE-2017-15129).

  The KVM implementation in the Linux kernel through 4.14.7 allows attackers
  to obtain potentially sensitive information from kernel memory, aka a
  write_mmio stack-based out-of-bounds read, related to arch/x86/kvm/x86.c
  and include/trace/events/kvm.h (CVE-2017-17741).

Ran stress tests and glmark2.
Networking and NFS OK.  Resumed a session under virtualbox which started a 330 package update.  Sound and video running - vlc and a video with subtitles.
Installed task-printing and started cups server.  Added an HP wifi printer under HPLIP and printed a test-page.  All looking good so far.
