- Fix build breakage caused by missing security key objects: + Modify openssh-7.7p1-cavstest-ctr.patch. + Modify openssh-7.7p1-cavstest-kdf.patch. + Add openssh-link-with-sk.patch. - Add openssh-fips-ensure-approved-moduli.patch (bsc#1177939). This ensures only approved DH parameters are used in FIPS mode. - Add openssh-8.1p1-ed25519-use-openssl-rng.patch (bsc#1173799). This uses OpenSSL's RAND_bytes() directly instead of the internal ChaCha20-based implementation to obtain random bytes for Ed25519 curve computations. This is required for FIPS compliance.

There are following changes in default settings of ssh client and server: * Accepting and sending of locale environment variables in protocol 2 is enabled. * PAM authentication is enabled and mostly even required, do not turn it off. * root authentiation with password is enabled by default (PermitRootLogin yes). NOTE: this has security implications and is only done in order to not change behaviour of the server in an update. We strongly suggest setting this option either "prohibit-password" or even better to "no" (which disables direct remote root login entirely). * DSA authentication is enabled by default for maximum compatibility. NOTE: do not use DSA authentication since it is being phased out for a reason - the size of DSA keys is limited by the standard to 1024 bits which cannot be considered safe any more. * Accepting all RFC4419 specified DH group parameters. See KexDHMin in ssh_config and sshd_config manual pages. For more information on differences in SUSE OpenSSH package see README.FIPS
