ECDH/ECDSA compliance fix: these methods vary the hash function they use
(SHA256/384/512) depending on the length of the curve in use. The previous
code incorrectly used SHA256 in all cases.
This fix will cause authentication failure when using 384 or 521-bit curve
keys if one peer hasn't been upgraded and the other has. (256-bit curve
keys work ok). In particular you may need to specify HostkeyAlgorithms
when connecting to a server that has not been upgraded from an upgraded
client.

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
better performance than plain DH and DSA at the same equivalent symmetric
key length, as well as much shorter keys.
Only the mandatory sections of RFC5656 are implemented, specifically the
three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
ECDSA. Point compression (optional in RFC5656 is NOT implemented).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.

[ssh.c]
close any extra file descriptors inherited from parent at start and
reopen stdin/stdout to /dev/null when forking for ControlPersist.
prevents tools that fork and run a captive ssh for communication from
failing to exit when the ssh completes while they wait for these fds to
close. The inherited fds may persist arbitrarily long if a background
mux master has been started by ControlPersist. cvs and scp were effected
by this.

[key.c servconf.c servconf.h sshd.8 sshd_config.5]
add some optional indirection to matching of principal names listed
in certificates. Currently, a certificate must include the a user's name
to be accepted for authentication. This change adds the ability to
specify a list of certificate principal names that are acceptable.
When authenticating using a CA trusted through ~/.ssh/authorized_keys,
this adds a new principals="name1[,name2,...]" key option.
For CAs listed through sshd_config's TrustedCAKeys option, a new config
option "AuthorizedPrincipalsFile" specifies a per-user file containing
the list of acceptable names.
If either option is absent, the current behaviour of requiring the
username to appear in principals continues to apply.
These options are useful for role accounts, disjoint account namespaces
and "user@realm"-style naming policies in certificates.

Add support for certificate key types for users and hosts.
OpenSSH certificate key types are not X.509 certificates, but a much
simpler format that encodes a public key, identity information and
some validity constraints and signs it with a CA key. CA keys are
regular SSH keys. This certificate style avoids the attack surface
of X.509 certificates and is very easy to deploy.
Certified host keys allow automatic acceptance of new host keys
when a CA certificate is marked as trusted in ~/.ssh/known_hosts.
see VERIFYING HOST KEYS in ssh(1) for details.
Certified user keys allow authentication of users when the signing
CA key is marked as trusted in authorized_keys. See "AUTHORIZED_KEYS
FILE FORMAT" in sshd(8) for details.
Certificates are minted using ssh-keygen(1), documentation is in
the "CERTIFICATES" section of that manpage.
Documentation on the format of certificates is in the file

[channels.c channels.h clientloop.c clientloop.h mux.c nchan.c ssh.c]
rewrite ssh(1) multiplexing code to a more sensible protocol.
The new multiplexing code uses channels for the listener and
accepted control sockets to make the mux master non-blocking, so
no stalls when processing messages from a slave.
avoid use of fatal() in mux master protocol parsing so an errant slave
process cannot take down a running master.
implement requesting of port-forwards over multiplexed sessions. Any
port forwards requested by the slave are added to those the master has
established.
add support for stdio forwarding ("ssh -W host:port ...") in mux slaves.
document master/slave mux protocol so that other tools can use it to
control a running ssh(1). Note: there are no guarantees that this
protocol won't be incompatibly changed (though it is versioned).

[Makefile.in]
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).

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.

Do not pass "0" strings as ports to getaddrinfo because the lookups

#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.

based on a patch from miklos AT szeredi.hu (bz#1399)
also add a "df" command to the sftp client that uses the
statvfs@openssh.com to produce a df(1)-like display of filesystem
space and inode utilisation

Enable the AllowAgentForwarding option in sshd_config (global and match

As the man page states:
``Note that disabling Agent forwarding does not improve security
unless users are also denied shell access, as they can always install
their own forwarders.''

[ssh.c sshd.c]
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.

[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().

[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.

Try additional addresses when connecting to a port forward destination
