# The patch below adds support for the deprecated 'gssapi' authentication
# mechanism to OpenSSH 3.8p1. The newer 'gssapi-with-mic' mechanism is included
# in this release. The use of 'gssapi' is deprecated due to the presence of
# potential man-in-the-middle attacks, which 'gssapi-with-mic' is not
# susceptible to.
#
# To use the patch apply it to a OpenSSH 3.8p1 source tree. After compiling,
# backwards compatibility may be obtained by supplying the
# 'GssapiEnableMitmAttack yes' option to either the client or server.
#
# It should be noted that this patch is being made available purely as a means
# of easing the process of moving to OpenSSH 3.8p1. Any new installations are
# recommended to use the 'gssapi-with-mic' mechanism. Existing installations
# are encouraged to upgrade as soon as possible.

Accepting request 222365 from home:pcerny:factory - Update of the underlying OpenSSH to 6.5p1 - Update to 6.5p1 Features since 6.4p1: * ssh(1), sshd(8): support for key exchange using ECDH in Daniel Bernstein's Curve25519; default when both the client and server support it. * ssh(1), sshd(8): support for Ed25519 as a public key type fo rboth server and client. Ed25519 is an EC signature offering better security than ECDSA and DSA and good performance. * Add a new private key format that uses a bcrypt KDF to better protect keys at rest. Used unconditionally for Ed25519 keys, on demand for other key types via the -o ssh-keygen(1) option. Intended to become default in the near future. Details documented in PROTOCOL.key. * ssh(1), sshd(8): new transport cipher "chacha20-poly1305@openssh.com" combining Daniel Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an authenticated encryption mode. Details documented PROTOCOL.chacha20poly1305. * ssh(1), sshd(8): refuse RSA keys from old proprietary clients and servers that use the obsolete RSA+MD5 signature scheme. It will still be possible to connect with these clients/servers but only DSA keys will be accepted, and OpenSSH will refuse connection entirely in a future release. * ssh(1), sshd(8): refuse old proprietary clients and servers that use a weaker key exchange hash calculation. * ssh(1): increase the size of the Diffie-Hellman groups requested for each symmetric key size. New values from NIST Special Publication 800-57 with the upper limit specified by OBS-URL: https://build.opensuse.org/request/show/222365 OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=63

Ed25519 is an EC signature offering better security than ECDSA and DSA and good performance. * Add a new private key format that uses a bcrypt KDF to better protect keys at rest. Used unconditionally for Ed25519 keys, on demand for other key types via the -o ssh-keygen(1) option. Intended to become default in the near future. Details documented in PROTOCOL.key. * ssh(1), sshd(8): new transport cipher "chacha20-poly1305@openssh.com" combining Daniel Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an authenticated encryption mode. Details documented PROTOCOL.chacha20poly1305. * ssh(1), sshd(8): refuse RSA keys from old proprietary clients and servers that use the obsolete RSA+MD5 signature scheme. It will still be possible to connect with these clients/servers but only DSA keys will be accepted, and OpenSSH will refuse connection entirely in a future release. * ssh(1), sshd(8): refuse old proprietary clients and servers that use a weaker key exchange hash calculation. * ssh(1): increase the size of the Diffie-Hellman groups requested for each symmetric key size.

Accepting request 222365 from home:pcerny:factory - Update of the underlying OpenSSH to 6.5p1 - Update to 6.5p1 Features since 6.4p1: * ssh(1), sshd(8): support for key exchange using ECDH in Daniel Bernstein's Curve25519; default when both the client and server support it. * ssh(1), sshd(8): support for Ed25519 as a public key type fo rboth server and client. Ed25519 is an EC signature offering better security than ECDSA and DSA and good performance. * Add a new private key format that uses a bcrypt KDF to better protect keys at rest. Used unconditionally for Ed25519 keys, on demand for other key types via the -o ssh-keygen(1) option. Intended to become default in the near future. Details documented in PROTOCOL.key. * ssh(1), sshd(8): new transport cipher "chacha20-poly1305@openssh.com" combining Daniel Bernstein's ChaCha20 stream cipher and Poly1305 MAC to build an authenticated encryption mode. Details documented PROTOCOL.chacha20poly1305. * ssh(1), sshd(8): refuse RSA keys from old proprietary clients and servers that use the obsolete RSA+MD5 signature scheme. It will still be possible to connect with these clients/servers but only DSA keys will be accepted, and OpenSSH will refuse connection entirely in a future release. * ssh(1), sshd(8): refuse old proprietary clients and servers that use a weaker key exchange hash calculation. * ssh(1): increase the size of the Diffie-Hellman groups requested for each symmetric key size. New values from NIST Special Publication 800-57 with the upper limit specified by OBS-URL: https://build.opensuse.org/request/show/222365 OBS-URL: https://build.opensuse.org/package/show/network/openssh?expand=0&rev=63
