[ssh_config channels.c ssh.1 channels.h ssh.c] Add a 'netcat mode' (ssh -W). This connects stdio on the client to a single port forward on the server. This allows, for example, using ssh as a ProxyCommand to route connections via intermediate servers. bz #1618, man page help from jmc@, ok markus@

[channels.c ssh.1 servconf.c sshd_config.5 sshd.c channels.h servconf.h ssh-keyscan.1 ssh-keyscan.c readconf.c sshconnect.c misc.c ssh.c readconf.h scp.1 sftp.1 ssh_config.5 misc.h] Remove RoutingDomain from ssh since it's now not needed. It can be replaced with "route exec" or "nc -V" as a proxycommand. "route exec" also ensures that trafic such as DNS lookups stays withing the specified routingdomain. For example (from reyk): # route -T 2 exec /usr/sbin/sshd or inherited from the parent process $ route -T 2 exec sh $ ssh 10.1.2.3 ok deraadt@ markus@ stevesk@ reyk@

[ssh.c sftp.c scp.c] When passing user-controlled options with arguments to other programs, pass the option and option argument as separate argv entries and not smashed into one (e.g., as -l foo and not -lfoo). Also, always pass a "--" argument to stop option parsing, so that a positional argument that starts with a '-' isn't treated as an option. This fixes some error cases as well as the handling of hostnames and filenames that start with a '-'. Based on a diff by halex@ ok halex@ djm@ deraadt@

[PROTOCOL ssh.c serverloop.c] Add a no-more-sessions@openssh.com global request extension that the client sends when it knows that it will never request another session (i.e. when session multiplexing is disabled). This allows a server to disallow further session requests and terminate the session. Why would a non-multiplexing client ever issue additional session requests? It could have been attacked with something like SSH'jack: http://www.storm.net.nz/projects/7 feedback & ok markus

[clientloop.c clientloop.h ssh.c] Use new channel status confirmation callback system to properly deal with "important" channel requests that fail, in particular command exec, shell and subsystem requests. Previously we would optimistically assume that the requests would always succeed, which could cause hangs if they did not (e.g. when the server runs out of fds) or were unimplemented by the server (bz #1384) Also, properly report failing multiplex channel requests via the mux client stderr (subject to LogLevel in the mux master) - better than silently failing. most bits ok markus@ (as part of a larger diff)

[auth-options.c auth1.c channels.c channels.h clientloop.c gss-serv.c] [monitor.c monitor_wrap.c nchan.c servconf.c serverloop.c session.c] [ssh.c sshd.c] Implement a channel success/failure status confirmation callback mechanism. Each channel maintains a queue of callbacks, which will be drained in order (RFC4253 guarantees confirm messages are not reordered within an channel). Also includes a abandonment callback to clean up if a channel is closed without sending confirmation messages. This probably shouldn't happen in compliant implementations, but it could be abused to leak memory. ok markus@ (as part of a larger diff)

[ssh.c sshconnect.c sshconnect.h] make ssh(1)'s ConnectTimeout option apply to both the TCP connection and SSH banner exchange (previously it just covered the TCP connection).
