When updating hostkeys, accept RSA keys if HostkeyAlgorithms contains any RSA keytype. Previously, ssh could ignore RSA keys when any of the ssh-rsa-sha2-* methods was enabled in HostkeyAlgorithms nit ssh-rsa (SHA1 signatures) was not. bz#2650 reported by Luis Ressel; ok dtucker@ Upstream-ID: c5e8cfee15c42f4a05d126158a0766ea06da79d2

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

refactor activation of rekeying This makes automatic rekeying internal to the packet code (previously the server and client loops needed to assist). In doing to it makes application of rekey limits more accurate by accounting for packets about to be sent as well as packets queued during rekeying events themselves. Based on a patch from dtucker@ which was in turn based on a patch Aleksander Adamowski in bz#2521; ok markus@ Upstream-ID: a441227fd64f9739850ca97b4cf794202860fcd8

fix setting/clearing of TTY raw mode around UpdateHostKeys=ask confirmation question; reported by Herb Goldman
2015-02-21upstream commitdjm@openbsd.org
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)

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@

[channels.c channels.h clientloop.c] Add an "ABANDONED" channel state and use for mux sessions that are disconnected via the ~. escape sequence. Channels in this state will be able to close if the server responds, but do not count as active channels. This means that if you ~. all of the mux clients when using ControlPersist on a broken network, the backgrounded mux master will exit when the Control Persist time expires rather than hanging around indefinitely. bz#1917, also reported and tested by tedu@. ok djm@ markus@.
