     [authfd.c ssh-add.c authfd.h]
     Do not fall back to adding keys without contraints (ssh-add -c / -t ...)
     when the agent refuses the constrained add request. This was a useful
     migration measure back in 2002 when constraints were new, but just
     adds risk now.

     fix a race condition in ssh-agent that could result in a wedged or
     spinning agent: don't read off the end of the allocated fd_sets, and
     don't issue blocking read/write on agent sockets - just fall back to
     select() on retriable read/write errors. bz#1633 reported and tested

    originally from Doke Scott, ok djm@
 - (dtucker) [clientloop.c configure.ac defines.h] Make the client's IO buffer

   PrintLastLog work on AIX.  Based in part on a patch from Miguel Sanders.

     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).

     because parse_forward() is now used to parse all forward types (DLR),

     [auth2-none.c auth2.c]
     Make protocol 2 MaxAuthTries behaviour a little more sensible:
     Check whether client has exceeded MaxAuthTries before running
     an authentication method and skip it if they have, previously it
     would always allow one try (for "none" auth).
     Preincrement failure count before post-auth test - previously this
     checked and postincremented, also to allow one "none" try.
     Together, these two changes always count the "none" auth method
     which could be skipped by a malicious client (e.g. an SSH worm)
     to get an extra attempt at a real auth method. They also make
     MaxAuthTries=0 a useful way to block users entirely (esp. in a
     sshd_config Match block).
     Also, move sending of any preauth banner from "none" auth method
     to the first call to input_userauth_request(), so worms that skip
     the "none" method get to see it too.

     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.

     deraadt@ djm@
     djm belives that the reason for the "0" strings is to ensure that
     it's not possible to call getaddrinfo with both host and port being
     NULL.  In the case of canohost.c host is a local array.  In the
     case of sshconnect.c, it's checked for null immediately before use.
     In dns.c it ultimately comes from ssh.c:main() and is guaranteed to
     be non-null but it's not obvious, so I added a warning message in
     case it is ever passed a null.

     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.

     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().

     [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.
