[ssh.c ssh_config.5] Add a %C escape sequence for LocalCommand and ControlPath that expands to a unique identifer based on a has of the tuple of (local host, remote user, hostname, port). Helps avoid exceeding sockaddr_un's miserly pathname limits for mux control paths. bz#2220, based on patch from mancha1 AT zoho.com; ok markus@

[readconf.c readconf.h ssh.c ssh_config.5] reparse ssh_config and ~/.ssh/config if hostname canonicalisation changes the hostname. This allows users to write configurations that always refer to canonical hostnames, e.g. CanonicalizeHostname yes CanonicalDomains int.example.org example.org CanonicalizeFallbackLocal no Host *.int.example.org Compression off Host *.example.org User djm ok markus@

Inspired by and similar to Adam Langley's proposal for TLS: http://tools.ietf.org/html/draft-agl-tls-chacha20poly1305-03 but differs in layout used for the MAC calculation and the use of a second ChaCha20 instance to separately encrypt packet lengths.

[readconf.c ssh_config.5] rename "command" subclause of the recently-added "Match" keyword to "exec"; it's shorter, clearer in intent and we might want to add the ability to match against the command being executed at the remote end in the future.

[readconf.c readconf.h roaming_client.c ssh.1 ssh.c ssh_config.5] [sshconnect.c sshconnect.h] Implement client-side hostname canonicalisation to allow an explicit search path of domain suffixes to use to convert unqualified host names to fully-qualified ones for host key matching.

[readconf.c readconf.h ssh_config.5 sshconnect.c] Add a ssh_config ProxyUseFDPass option that supports the use of ProxyCommands that establish a connection and then pass a connected file descriptor back to ssh(1).

ECDH and ECDSA offer better performance than plain DH and DSA at the same equivalent symmetric key length, as well as much shorter keys. Only the mandatory sections of RFC5656 are implemented, specifically the three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and ECDSA. Point compression (optional in RFC5656 is NOT implemented). Certificate host and user keys using the new ECDSA key types are supported.
