ssh proxy mux mode (-O proxy; idea from Simon Tatham): - mux client speaks the ssh-packet protocol directly over unix-domain socket. - mux server acts as a proxy, translates channel IDs and relays to the server. - no filedescriptor passing necessary. - combined with unix-domain forwarding it's even possible to run mux client and server on different machines. feedback & ok djm@ Upstream-ID: 666a2fb79f58e5c50e246265fb2b9251e505c25b

Add a ProxyJump ssh_config(5) option and corresponding -J ssh(1) command-line flag to allow simplified indirection through a SSH bastion or "jump host". These options construct a proxy command that connects to the specified jump host(s) (more than one may be specified) and uses port-forwarding to establish a connection to the next destination. This codifies the safest way of indirecting connections through SSH servers and makes it easy to use. ok markus@ Upstream-ID: fa899cb8b26d889da8f142eb9774c1ea36b04397

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.
