   - djm@cvs.openbsd.org 2008/07/02 12:36:39
     [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.

     [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.

     [dns.c canohost.c sshconnect.c]
     Do not pass "0" strings as ports to getaddrinfo because the lookups
     can slow things down and we never use the service info anyway. bz
     #859, patch from YOSHIFUJI Hideaki and John Devitofranceschi.  ok
     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.

     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

     Performing certain operations on queue.h data structurs produced
     funny results.  An example is calling  LIST_REMOVE on the same
     element twice. This will not fail, but result in a data structure
     referencing who knows what. Prevent these accidents by NULLing some
     fields on remove and replace. This way, either a panic or segfault
     will be produced on the faulty operation.

     Add a new MAC algorithm for data integrity, UMAC-64 (not default yet,
     must specify umac-64@openssh.com). Provides about 20% end-to-end speedup
     compared to hmac-md5. Represents a different approach to message
     authentication to that of HMAC that may be beneficial if HMAC based on
     one of its underlying hash algorithms is found to be vulnerable to a
     new attack.  http://www.ietf.org/rfc/rfc4418.txt

 - (dtucker) [auth.c openbsd-compat/port-aix.c] Bug #1207: always call

   login count.  Previously this would only happen when an interactive
   session starts (ie when a pty is allocated) but this means that accounts
   that have primarily non-interactive sessions (eg scp's) may gradually
   accumulate enough failures to lock out an account.  This change may have
   a side effect of creating two audit records, one with a tty of "ssh"
   corresponding to the authentication and one with the allocated pty per
   interactive session.

     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.

     Add support for tun(4) forwarding over OpenSSH, based on an idea and
     initial channel code bits by markus@. This is a simple and easy way to
     use OpenSSH for ad hoc virtual private network connections, e.g.
     administrative tunnels or secure wireless access. It's based on a new
     ssh channel and works similar to the existing TCP forwarding support,
     except that it depends on the tun(4) network interface on both ends of
     the connection for layer 2 or layer 3 tunneling. This diff also adds
     support for LocalCommand in the ssh(1) client.

     (point-to-point, default) modes. configuration is done using the
     Tunnel (yes|point-to-point|ethernet|no) option is ssh_config(5) and

     [ssh-keygen.c]
     change DSA default back to 1024, as it's defined for 1024 bits only
     and this causes interop problems with other clients.  moreover,
     in order to improve the security of DSA you need to change more
     components of DSA key generation (e.g. the internal SHA1 hash);
