Expand tildes in filenames passed to -i before checking whether or not the identity file exists. This means that if the shell doesn't do the expansion (eg because the option and filename were given as a single argument) then we'll still add the key. bz#2481, ok markus@ Upstream-ID: db1757178a14ac519e9a3e1a2dbd21113cb3bfc6

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)

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
