  Security issues fixed:

  - CVE-2017-16837: Fix tbootfailed to validate a number of immutable
  function pointers, which could allow an attacker to bypass the chain of
  trust and execute arbitrary code (boo#1068390).

  - Make tboot package compatible with OpenSSL 1.1.0 for SLE-15 support
  (boo#1067229).

  Bug fixes:

  - Update to new upstream version. See the referenced release notes for details (1.9.6
  1.9.5, FATE#321510  1.9.4, FATE#320665  1.8.3, FATE#318542).

  - Fix some gcc7 warnings that lead to errors. (boo#1041264)

  - Fix wrong pvops kernel config matching (boo#981948)

  - Fix an excessive stack usage pattern that could lead to resets/crashes
  (boo#967441)

  - fixes a boot issue on Skylake (boo#964408)

  - Trim filler words from description  use modern macros over shell vars.

  - Add reproducible.patch to call gzip -n to make build fully reproducible.");
