[ssh_config.5 key.h readconf.c readconf.h ssh-keygen.1 ssh-keygen.c key.c sshconnect.c] Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the graphical hash visualization schemes known as "random art", and by Dan Kaminsky's musings on the subject during a BlackOp talk at the 23C3 in Berlin. Scientific publication (original paper): "Hash Visualization: a New Technique to improve Real-World Security", Perrig A. and Song D., 1999, International Workshop on Cryptographic Techniques and E-Commerce (CrypTEC '99) http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf The algorithm used here is a worm crawling over a discrete plane, leaving a trace (augmenting the field) everywhere it goes. Movement is taken from dgst_raw 2bit-wise. Bumping into walls makes the respective movement vector be ignored for this turn, thus switching to the other color of the chessboard. Graphs are not unambiguous for now, because circles in graphs can be walked in either direction. discussions with several people, help, corrections and ok markus@ djm@

[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

[sftp.c sftp-client.c sftp-client.h] Have the sftp client store the statvfs replies in wire format, which prevents problems when the server's native sizes exceed the client's. Also extends the sizes of the remaining 32bit wire format to 64bit, they're specified as unsigned long in the standard.

[clientloop.c] unbreak tree by committing this bit that I missed from: Fix sending tty modes when stdin is not a tty (bz#1199).

[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.

[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)

[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@
