[auth.h auth2.c monitor.c monitor.h monitor_wrap.c monitor_wrap.h] [readconf.c readconf.h servconf.c servconf.h ssh2.h ssh_config.5] [sshconnect2.c sshd_config.5 jpake.c jpake.h schnorr.c auth2-jpake.c] [Makefile.in] Add support for an experimental zero-knowledge password authentication method using the J-PAKE protocol described in F. Hao, P. Ryan, "Password Authenticated Key Exchange by Juggling", 16th Workshop on Security Protocols, Cambridge, April 2008. This method allows password-based authentication without exposing the password to the server. Instead, the client and server exchange cryptographic proofs to demonstrate of knowledge of the password while revealing nothing useful to an attacker or compromised endpoint. This is experimental, work-in-progress code and is presently compiled-time disabled (turn on -DJPAKE in Makefile.inc). "just commit it. It isn't too intrusive." deraadt@

[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@

[servconf.c servconf.h session.c sshd_config.5] Enable the AllowAgentForwarding option in sshd_config (global and match context), to specify if agents should be permitted on the server. As the man page states: ``Note that disabling Agent forwarding does not improve security unless users are also denied shell access, as they can always install their own forwarders.'' ok djm@, ok and a mild frown markus@

[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@.

[sshd.c servconf.h servconf.c sshd_config.5 auth.c] Add support for conditional directives to sshd_config via a "Match" keyword, which works similarly to the "Host" directive in ssh_config. Lines after a Match line override the default set in the main section if the condition on the Match line is true, eg AllowTcpForwarding yes Match User anoncvs AllowTcpForwarding no will allow port forwarding by all users except "anoncvs". Currently only a very small subset of directives are supported. ok djm@
