UpdateHostKeys fixes: I accidentally changed the format of the hostkeys@openssh.com messages last week without changing the extension name, and this has been causing connection failures for people who are running -current. First reported by sthen@ s/hostkeys@openssh.com/hostkeys-00@openssh.com/ Change the name of the proof message too, and reorder it a little. Also, UpdateHostKeys=ask is incompatible with ControlPersist (no TTY available to read the response) so disable UpdateHostKeys if it is in ask mode and ControlPersist is active (and document this)
2015-02-17upstream commitdjm@openbsd.org
Revise hostkeys@openssh.com hostkey learning extension. The client will not ask the server to prove ownership of the private halves of any hitherto-unseen hostkeys it offers to the client. Allow UpdateHostKeys option to take an 'ask' argument to let the user manually review keys offered. ok markus@
2015-02-03upstream commitdjm@openbsd.org
turn UpdateHostkeys off by default until I figure out mlarkin@'s warning message; requested by deraadt@
2015-01-30upstream commitdjm@openbsd.org
Add a ssh_config HostbasedKeyType option to control which host public key types are tried during hostbased authentication. This may be used to prevent too many keys being sent to the server, and blowing past its MaxAuthTries limit. bz#2211 based on patch by Iain Morgan; ok markus@
2015-01-27upstream commitdjm@openbsd.org
correct description of UpdateHostKeys in ssh_config.5 and add it to -o lists for ssh, scp and sftp; pointed out by jmc@
2015-01-27upstream commitdjm@openbsd.org
Host key rotation support. Add a hostkeys@openssh.com protocol extension (global request) for a server to inform a client of all its available host key after authentication has completed. The client may record the keys in known_hosts, allowing it to upgrade to better host key algorithms and a server to gracefully rotate its keys. The client side of this is controlled by a UpdateHostkeys config option (default on). ok markus@

Tweak config reparsing with host canonicalisation Make the second pass through the config files always run when hostname canonicalisation is enabled. Add a "Match canonical" criteria that allows ssh_config Match blocks to trigger only in the second config pass. Add a -G option to ssh that causes it to parse its configuration and dump the result to stdout, similar to "sshd -T" Allow ssh_config Port options set in the second config parse phase to be applied (they were being ignored). bz#2267 bz#2286; ok markus

[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.
