- (djm) [sshpty.c] bz#1419: OSX uses cloning ptys that automagically
set ownership and modes, so avoid explicitly setting them
- (djm) [configure.ac loginrec.c] bz#1421: fix lastlog support for OSX.
OSX provides a getlastlogxbyname function that automates the reading of
a lastlog file. Also, the pututxline function will update lastlog so
there is no need for loginrec.c to do it explicitly. Collapse some
overly verbose code while I'm in there.
20090201
- (dtucker) [defines.h sshconnect.c] INET6_ADDRSTRLEN is now needed in
channels.c too, so move the definition for non-IP6 platforms to defines.h
where it can be shared.
20090129
- (tim) [contrib/cygwin/ssh-host-config] Patch from Corinna Vinschen.
If the CYGWIN environment variable is empty, the installer script
should not install the service with an empty CYGWIN variable, but
rather without setting CYGWNI entirely.
- (tim) [contrib/cygwin/ssh-host-config] Whitespace cleanup. No code changes.
20090128
- (tim) [contrib/cygwin/ssh-host-config] Patch from Corinna Vinschen.
Changes to work on Cygwin 1.5.x as well as on the new Cygwin 1.7.x.
The information given for the setting of the CYGWIN environment variable
is wrong for both releases so I just removed it, together with the
unnecessary (Cygwin 1.5.x) or wrong (Cygwin 1.7.x) default setting.

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).

[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.

[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.
