[canohost.c canohost.h channels.c channels.h clientloop.c readconf.c] [readconf.h serverloop.c ssh.c] support remote port forwarding with a zero listen port (-R0:...) to dyamically allocate a listen port at runtime (this is actually specified in rfc4254); bz#1003 ok markus@

[channels.c channels.h session.c] don't call isatty() on a pty master, instead pass a flag down to channel_set_fds() indicating that te fds refer to a tty. Fixes a hang on exit on Solaris (bz#1463) in portable but is actually a generic bug; ok dtucker deraadt markus

[clientloop.h channels.h clientloop.c channels.c mux.c] The multiplexing escape char handler commit last night introduced a small memory leak per session; plug it.
2008-06-13 - djm@cvs.openbsd.org 2008/06/12 03:40:52Darren Tucker
[clientloop.h mux.c channels.c clientloop.c channels.h] Enable ~ escapes for multiplex slave sessions; give each channel its own escape state and hook the escape filters up to muxed channels. bz #1331 Mux slaves do not currently support the ~^Z and ~& escapes. NB. this change cranks the mux protocol version, so a new ssh mux client will not be able to connect to a running old ssh mux master. ok dtucker@

[sshd.c channels.h channels.c log.c servconf.c log.h servconf.h sshd.8] Add extended test mode (-T) and connection parameters for test mode (-C). -T causes sshd to write its effective configuration to stdout and exit. -C causes any relevant Match rules to be applied before output. The combination allows tesing of the parser and config files. ok deraadt djm

[channels.c channels.h clientloop.c serverloop.c] Try additional addresses when connecting to a port forward destination whose DNS name resolves to more than one address. The previous behaviour was to try the first address and give up. Reported by stig AT venaas.com in bz#343 great feedback and ok markus@

[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)

2008-02-10 - djm@cvs.openbsd.org 2008/01/19 23:02:40Damien Miller
[channels.c] When we added support for specified bind addresses for port forwards, we added a quirk SSH_OLD_FORWARD_ADDR. There is a bug in our handling of this for -L port forwards that causes the client to listen on both v4 and v6 addresses when connected to a server with this quirk, despite having set 0.0.0.0 as a bind_address. report and patch from Jan.Pechanec AT Sun.COM; ok dtucker@

[channels.c channels.h servconf.c sshd_config.5] Add PermitOpen directive to sshd_config which is equivalent to the "permitopen" key option. Allows server admin to allow TCP port forwarding only two specific host/port pairs. Useful when combined with Match. If permitopen is used in both sshd_config and a key option, both must allow a given connection before it will be permitted. Note that users can still use external forwarders such as netcat, so to be those must be controlled too for the limits to be effective. Feedback & ok djm@, man page corrections & ok jmc@.
