openssh/openssh-7.2p2-remove_xauth_cookies_on_exit.patch
Petr Cerny 6dac324cb7 Accepting request 407066 from home:pcerny:factory
- enable support for SSHv1 protocol and discourage its usage
  (bsc#983307)
- enable DSA by default for backward compatibility and discourage
  its usage (bsc#983784)
  [openssh-7.2p2-allow_DSS_by_default.patch]

- upgrade to 7.2p2
  upstream package without any SUSE patches
  Distilled upstream log:
- OpenSSH 6.7
  Potentially-incompatible changes:
  * sshd(8): The default set of ciphers and MACs has been
    altered to remove unsafe algorithms. In particular, CBC
    ciphers and arcfour* are disabled by default.
    The full set of algorithms remains available if configured
    explicitly via the Ciphers and MACs sshd_config options.
  * sshd(8): Support for tcpwrappers/libwrap has been removed.
  * OpenSSH 6.5 and 6.6 have a bug that causes ~0.2% of
    connections using the curve25519-sha256@libssh.org KEX
    exchange method to fail when connecting with something that
    implements the specification correctly. OpenSSH 6.7 disables
    this KEX method when speaking to one of the affected
    versions.
  New Features:
  * ssh(1), sshd(8): Add support for Unix domain socket
    forwarding. A remote TCP port may be forwarded to a local
    Unix domain socket and vice versa or both ends may be a Unix
    domain socket.
  * ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for
    ED25519 key types.
