[ssh_config.5 sshd_config.5] the default kex is now curve25519-sha256@libssh.org

[readconf.c servconf.c ssh_config.5 sshd_config.5] Disallow empty Match statements and add "Match all" which matches everything. ok djm, man page help jmc@

[ssh_config.5] tweak the "exec" description, as worded by djm;
2013-10-23 - djm@cvs.openbsd.org 2013/10/20 06:19:28Damien Miller
[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 ssh.1 ssh.c ssh_config.5] s/canonicalise/canonicalize/ for consistency with existing spelling, e.g. authorized_keys; pointed out by naddy@

[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. This is particularly useful for host certificates, which would otherwise need to list unqualified names alongside fully-qualified ones (and this causes a number of problems). "looks fine" markus@

[readconf.c readconf.h ssh-keysign.c ssh.c ssh_config.5] add a "Match" keyword to ssh_config that allows matching on hostname, user and result of arbitrary commands. "nice work" markus@

[ssh.1 ssh_config.5] some proxyusefdpass tweaks;
2013-08-21 - djm@cvs.openbsd.org 2013/08/20 00:11:38Damien Miller
[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). This allows the ProxyCommand to exit rather than have to shuffle data back and forth and enables ssh to use getpeername, etc. to obtain address information just like it does with regular directly-connected sockets. ok markus@

[ssh-keygen.1 ssh.1 ssh_config.5 sshd.8 sshd_config.5] do not use Sx for sections outwith the man page - ingo informs me that stuff like html will render with broken links; issue reported by Eric S. Raymond, via djm
2013-07-18 - djm@cvs.openbsd.org 2013/06/21 00:37:49Damien Miller

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.
