[session.c] root should always be excluded from the test for /etc/nologin instead of having it always enforced even when marked as ignorenologin. This regressed when the logic was incompletely flipped around in rev 1.251 ok halex@ millert@

[channels.c session.c] bz#1750: fix requirement for /dev/null inside ChrootDirectory for internal-sftp accidentally introduced in r1.253 by removing the code that opens and dup /dev/null to stderr and modifying the channels code to read stderr but discard it instead; ok markus@

setpcred.
2010-03-07 - (dtucker) [session.c] Bug #1567: move setpcred call to before chroot andDarren Tucker
do not set real uid, since that's needed for the chroot, and will be set by permanently_set_uid.

[session.c] bz#1606: error when an attempt is made to connect to a server with ForceCommand=internal-sftp with a shell session (i.e. not a subsystem session). Avoids stuck client when attempting to ssh to such a service. ok dtucker@

2009-08-20 - (dtucker) [session.c openbsd-compat/port-aix.h] Bugs #1249 and #1567: moveDarren Tucker
the setpcred call on AIX to immediately before the permanently_set_uid(). Ensures that we still have privileges when we call chroot and pam_open_sesson. Based on a patch from David Leonard.

[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

[monitor.c monitor_wrap.c session.h servconf.c servconf.h session.c] [sshd_config sshd_config.5] Make the maximum number of sessions run-time controllable via a sshd_config MaxSessions knob. This is useful for disabling login/shell/subsystem access while leaving port-forwarding working (MaxSessions 0), disabling connection multiplexing (MaxSessions 1) or simply increasing the number of allows multiplexed sessions. Because some bozos are sure to configure MaxSessions in excess of the number of available file descriptors in sshd (which, at peak, might be as many as 9*MaxSessions), audit sshd to ensure that it doesn't leak fds on error paths, and make it fail gracefully on out-of-fd conditions - sending channel errors instead of than exiting with fatal(). bz#1090; MaxSessions config bits and manpage from junyer AT gmail.com 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)
