554 Add support for an experimental zero-knowledge password authentication
555 method using the J-PAKE protocol described in F. Hao, P. Ryan,
556 "Password Authenticated Key Exchange by Juggling", 16th Workshop on
557 Security Protocols, Cambridge, April 2008.
559 This method allows password-based authentication without exposing
560 the password to the server. Instead, the client and server exchange
561 cryptographic proofs to demonstrate of knowledge of the password while
562 revealing nothing useful to an attacker or compromised endpoint.
564 This is experimental, work-in-progress code and is presently
565 compiled-time disabled (turn on -DJPAKE in Makefile.inc).

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

1102 Introduce SSH Fingerprint ASCII Visualization, a technique inspired by the
1103 graphical hash visualization schemes known as "random art", and by
1104 Dan Kaminsky's musings on the subject during a BlackOp talk at the
1106 Scientific publication (original paper):
1107 "Hash Visualization: a New Technique to improve Real-World Security",

1109 Techniques and E-Commerce (CrypTEC '99)
1110 http://sparrow.ece.cmu.edu/~adrian/projects/validation/validation.pdf
1111 The algorithm used here is a worm crawling over a discrete plane,
1112 leaving a trace (augmenting the field) everywhere it goes.
1113 Movement is taken from dgst_raw 2bit-wise. Bumping into walls
1114 makes the respective movement vector be ignored for this turn,
1115 thus switching to the other color of the chessboard.
1116 Graphs are not unambiguous for now, because circles in graphs can be
1117 walked in either direction.

1147 #859, patch from YOSHIFUJI Hideaki and John Devitofranceschi. ok
1149 djm belives that the reason for the "0" strings is to ensure that
1150 it's not possible to call getaddrinfo with both host and port being
1151 NULL. In the case of canohost.c host is a local array. In the
1152 case of sshconnect.c, it's checked for null immediately before use.
1153 In dns.c it ultimately comes from ssh.c:main() and is guaranteed to
1154 be non-null but it's not obvious, so I added a warning message in
1155 case it is ever passed a null.

1482 Implement a channel success/failure status confirmation callback
1483 mechanism. Each channel maintains a queue of callbacks, which will
1484 be drained in order (RFC4253 guarantees confirm messages are not
1485 reordered within an channel).
1486 Also includes a abandonment callback to clean up if a channel is
1487 closed without sending confirmation messages. This probably
1488 shouldn't happen in compliant implementations, but it could be
1489 abused to leak memory.

1493 [sshd_config sshd_config.5]
1494 Make the maximum number of sessions run-time controllable via
1495 a sshd_config MaxSessions knob. This is useful for disabling
1496 login/shell/subsystem access while leaving port-forwarding working
1497 (MaxSessions 0), disabling connection multiplexing (MaxSessions 1) or
1498 simply increasing the number of allows multiplexed sessions.
1499 Because some bozos are sure to configure MaxSessions in excess of the
1500 number of available file descriptors in sshd (which, at peak, might be
1501 as many as 9*MaxSessions), audit sshd to ensure that it doesn't leak fds
1502 on error paths, and make it fail gracefully on out-of-fd conditions -
1503 sending channel errors instead of than exiting with fatal().

1507 [clientloop.c clientloop.h ssh.c]
1508 Use new channel status confirmation callback system to properly deal
1509 with "important" channel requests that fail, in particular command exec,
1510 shell and subsystem requests. Previously we would optimistically assume
1511 that the requests would always succeed, which could cause hangs if they
1512 did not (e.g. when the server runs out of fds) or were unimplemented by
1513 the server (bz #1384)
1514 Also, properly report failing multiplex channel requests via the mux
1515 client stderr (subject to LogLevel in the mux master) - better than
