OpenSSL now supports AES-NI in evp, not in an engine. We can now get
rid of the no longer maintained aesni engine, which was broken last
summer. Not only can OpenSSL now use AES-NI for everything it did
before we broke it last summer, but it can also use AES-NI for more
encryption modes than before, such as CTR.
Tested on amd64, both vanilla and in an i386 chroot.

*) Correct fix for CVE-2013-0169. The original didn't work on AES-NI
supporting platforms or when small records were transferred.
[Andy Polyakov, Steve Henson]
This is primarily a bugfix release.
Features:
* sshd(8): This release turns on pre-auth sandboxing sshd by default for
new installs, by setting UsePrivilegeSeparation=sandbox in sshd_config.
* ssh-keygen(1): Add options to specify starting line number and number of
lines to process when screening moduli candidates, allowing processing
of different parts of a candidate moduli file in parallel
* sshd(8): The Match directive now supports matching on the local (listen)
address and port upon which the incoming connection was received via
LocalAddress and LocalPort clauses.
* sshd(8): Extend sshd_config Match directive to allow setting AcceptEnv
and {Allow,Deny}{Users,Groups}
* Add support for RFC6594 SSHFP DNS records for ECDSA key types. bz#1978
* ssh-keygen(1): Allow conversion of RSA1 keys to public PEM and PKCS8
* sshd(8): Allow the sshd_config PermitOpen directive to accept "none" as
an argument to refuse all port-forwarding requests.
* sshd(8): Support "none" as an argument for AuthorizedPrincipalsFile
* ssh-keyscan(1): Look for ECDSA keys by default. bz#1971
* sshd(8): Add "VersionAddendum" to sshd_config to allow server operators
to append some arbitrary text to the server SSH protocol banner.
Bugfixes:
* ssh(1)/sshd(8): Don't spin in accept() in situations of file
descriptor exhaustion. Instead back off for a while.
* ssh(1)/sshd(8): Remove hmac-sha2-256-96 and hmac-sha2-512-96 MACs as
they were removed from the specification. bz#2023,
* sshd(8): Handle long comments in config files better. bz#2025
* ssh(1): Delay setting tty_flag so RequestTTY options are correctly
picked up. bz#1995
* sshd(8): Fix handling of /etc/nologin incorrectly being applied to root
on platforms that use login_cap.

agc-netpgp-standalone branch.
Rewrite the netpgpverify(1) functionality from RFC4880 up. This is a
completely new implementation, and uses its own bignum library derived
from libtommath. Apart from libz and libbz2, it just uses its own
library and is self-contained - this makes it easier to embed, and to
use from scripting languages.
netpgpverify(1) now verifies all the signed files i've thrown at it,
and the added bonus of using no functionality from libcrypto - all of
its bignum functionality comes from its own libnetpgpverify.so.
netpgpverify(1) now verifies not only signatures on binary files, but
also signatures on text documents. This fixes PR/46930. Please don't
start me on the hoops I had to jump through to calculate the digests
on text files; trust me, you will regret it.

Features:
* ssh-keygen(1): Add optional checkpoints for moduli screening
* ssh-add(1): new -k option to load plain keys (skipping certificates)
* sshd(8): Add wildcard support to PermitOpen, allowing things like
"PermitOpen localhost:*". bz #1857
* ssh(1): support for cancelling local and remote port forwards via the
multiplex socket. Use ssh -O cancel -L xx:xx:xx -R yy:yy:yy user@host"
to request the cancellation of the specified forwardings
* support cancellation of local/dynamic forwardings from ~C commandline
Bugfixes:
* ssh(1): ensure that $DISPLAY contains only valid characters before
using it to extract xauth data so that it can't be used to play local
shell metacharacter games.
* ssh(1): unbreak remote portforwarding with dynamic allocated listen ports
* scp(1): uppress adding '--' to remote commandlines when the first
argument does not start with '-'. saves breakage on some
difficult-to-upgrade embedded/router platforms
* ssh(1)/sshd(8): fix typo in IPQoS parsing: there is no "AF14" class,
but there is an "AF21" class
* ssh(1)/sshd(8): do not permit SSH2_MSG_SERVICE_REQUEST/ACCEPT during
rekeying
* ssh(1): skip attempting to create ~/.ssh when -F is passed
* sshd(8): unbreak stdio forwarding when ControlPersist is in use; bz#1943
* sshd(1): send tty break to pty master instead of (probably already
closed) slave side; bz#1859
* sftp(1): silence error spam for "ls */foo" in directory with files;
bz#1683
* Fixed a number of memory and file descriptor leaks
the client send its version string first if it is configured to speak
v2 only (the old hack of waiting to see the server version is only
really useful if you might be speaking v1 to some servers). The option
is on by default but can be disabled from the config file.
This aligns the OpenSSH client behavior with most other implementations
and eliminates a major source of connection delays and failures when
speaking SSH through particularly stupid proxies, of which, sadly, there
are many.
This change has also been submitted to OpenSSH as their bug #1999.
check for potentially exploitable overflows in asn1_d2i_read_bio
BUF_mem_grow and BUF_mem_grow_clean. Refuse attempts to shrink buffer
in CRYPTO_realloc_clean. (CVE-2012-2110)
explicitly seed the OpenSSL RNG in each new process rather than letting
it repeatedly open /dev/urandom to reseed, which depletes entropy severely.
Note that the OpenSSH part of this fix works better on NetBSD than it would
on many other platforms because on NetBSD, if you don't reopen /dev/urandom,
repeated reads don't deplete entropy. On other platforms, some other
approach might be required.
Note also that this problem does not arise on OpenBSD because OpenBSD seems
to have patched OpenSSL to seed the RAND functions from arc4random()! That
seems dangerous, so I am not taking that approach here.
