Add a RevokedKeys option to sshd_config and a @revoked marker to known_hosts to allow keys to me revoked and banned for user or host authentication. feedback and ok markus@

OpenSSH certificate key types are not X.509 certificates, but a much simpler format that encodes a public key, identity information and some validity constraints and signs it with a CA key. CA keys are regular SSH keys. This certificate style avoids the attack surface of X.509 certificates and is very easy to deploy. Certified host keys allow automatic acceptance of new host keys when a CA certificate is marked as sh/known_hosts. see VERIFYING HOST KEYS in ssh(1) for details. Certified user keys allow authentication of users when the signing CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS FILE FORMAT" in sshd(8) for details. Certificates are minted using ssh-keygen(1), documentation is in the "CERTIFICATES" section of that manpage. Documentation on the format of certificates is in the file PROTOCOL.certkeys feedback and ok markus@

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.

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@

[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)
