   An update that solves one vulnerability and has three fixes
   is now available.

Description:

   This strongswan update fixes the following security and non security
   issues.

   - Disallow brainpool elliptic curve groups in fips mode (bnc#856322).
   - Applied an upstream fix for a denial-of-service vulnerability, which can
     be triggered by an IKEv2 Key Exchange payload, that contains the
     Diffie-Hellman group 1025 (bsc#910491,CVE-2014-9221).
   - Adjusted whilelist of approved algorithms in fips mode (bsc#856322).
   - Updated strongswan-hmac package description (bsc#856322).
   - Disabled explicit gpg validation; osc source_validator does it.
   - Guarded fipscheck and hmac package in the spec file for >13.1.
   - Added generation of fips hmac hash files using fipshmac utility and a
     _fipscheck script to verify binaries/libraries/plugings shipped in the
     strongswan-hmac package. With enabled fips in the kernel, the ipsec
     script will call it before any action or in a enforced/manual "ipsec
     _fipscheck" call. Added config file to load openssl and kernel af-alg
     plugins, but not all the other modules which provide further/alternative
     algs. Applied a filter disallowing non-approved algorithms in fips mode.
     (fate#316931,bnc#856322).
   - Fixed file list in the optional (disabled) strongswan-test package.
   - Fixed build of the strongswan built-in integrity checksum library and
     enabled building it only on architectures tested to work.
   - Fix to use bug number 897048 instead 856322 in last changes entry.
   - Applied an upstream patch reverting to store algorithms in the
     registration order again as ordering them by identifier caused weaker
     algorithms to be proposed first by default (bsc#897512).
