Summary: Security update for strongswan

Details: 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).
