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.

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.

our version of GNU as decides to silently ignore it. Never versions on
other systems and Clang actually keep it around and create bad object

entry in the symbol table.
the "rep ret" trick is recommended by AMD as a branch prediction
optimization in certain circumstances (quoting their manual):
- any kind of branch (either conditional or unconditional) that has the
single-byte near-return RET instruction as its target
- a conditional branch that occurs in the code directly before the
single-byte near-return RET instruction.
Somewhere in this mess of .byte streams, corruption happens. Disassembly
only shows slightly different filling of alignment sequences, further
analysis is needed.
XXX This should be rewritten to be proper assembler code

1. read the public keyring
2. if a userid has been specified, use it
3. if not, check the configuration file (~/.gnupg/gpg.conf) for a
default user id
4, only read the secret keyring if we need to (decrypting or signing)
5. if signing, and we still don't have a userid, use the first key in
the secret keyring
6. if encrypting, and we still have no userid, use the first in the
public keyring

this is sort of a sidegrade onto the release branch. Changes against the
last version imported:
*) Backport libcrypto audit of return value checking from HEAD, not
all cases can be covered as some introduce binary incompatibilities.
[Steve Henson]
*) Redirect RSA operations to FIPS module including keygen,
encrypt, decrypt, sign and verify. Block use of non FIPS RSA methods.
[Steve Henson]
*) Add similar low level API blocking to ciphers.
[Steve Henson]
*) Low level digest APIs are not approved in FIPS mode: any attempt
to use these will cause a fatal error. Applications that *really* want
to use them can use the private_* version instead.
[Steve Henson]
*) Redirect cipher operations to FIPS module for FIPS builds.
[Steve Henson]
*) Redirect digest operations to FIPS module for FIPS builds.
[Steve Henson]
*) Update build system to add "fips" flag which will link in fipscanister.o
for static and shared library builds embedding a signature if needed.
[Steve Henson]
*) Output TLS supported curves in preference order instead of numerical
order. This is currently hardcoded for the highest order curves first.
This should be configurable so applications can judge speed vs strength.
[Steve Henson]
*) Add protection against ECDSA timing attacks as mentioned in the paper
by Billy Bob Brumley and Nicola Tuveri, see:
http://eprint.iacr.org/2011/232.pdf
[Billy Bob Brumley and Nicola Tuveri]
*) Add TLS v1.2 server support for client authentication.
[Steve Henson]
*) Add support for FIPS mode in ssl library: disable SSLv3, non-FIPS ciphers
and enable MD5.
[Steve Henson]
*) Functions FIPS_mode_set() and FIPS_mode() which call the underlying
FIPS modules versions.
[Steve Henson]
*) Add TLS v1.2 client side support for client authentication. Keep cache
of handshake records longer as we don't know the hash algorithm to use
until after the certificate request message is received.
[Steve Henson]
*) Initial TLS v1.2 client support. Add a default signature algorithms
extension including all the algorithms we support. Parse new signature
format in client key exchange. Relax some ECC signing restrictions for
TLS v1.2 as indicated in RFC5246.
[Steve Henson]
*) Add server support for TLS v1.2 signature algorithms extension. Switch
to new signature format when needed using client digest preference.
All server ciphersuites should now work correctly in TLS v1.2. No client
support yet and no support for client certificates.
[Steve Henson]
*) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
ciphersuites. At present only RSA key exchange ciphersuites work with
TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
and version checking.
[Steve Henson]
*) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
with this defined it will not be affected by any changes to ssl internal
structures. Add several utility functions to allow openssl application
to work with OPENSSL_NO_SSL_INTERN defined.
[Steve Henson]
*) Add SRP support.
[Tom Wu <tjw@cs.stanford.edu> and Ben Laurie]
*) Add functions to copy EVP_PKEY_METHOD and retrieve flags and id.
[Steve Henson]
*) Add EC_GFp_nistp224_method(), a 64-bit optimized implementation for
elliptic curve NIST-P224 with constant-time single point multiplication on
typical inputs. EC_GROUP_new_by_curve_name() will automatically use this
(while EC_GROUP_new_curve_GFp() currently won't and prefers the more
flexible implementations).
The implementation requires support for the nonstandard type __uint128_t,
and so is disabled by default. To include this in your build of OpenSSL,
use -DEC_NISTP224_64_GCC_128 on the Configure (or config) command line,
and run "make depend" (or "make update").
[Emilia K<E4>sper <emilia.kasper@esat.kuleuven.be> (Google)]
*) Permit abbreviated handshakes when renegotiating using the function
SSL_renegotiate_abbreviated().
[Robin Seggelmann <seggelmann@fh-muenster.de>]
*) Add call to ENGINE_register_all_complete() to
ENGINE_load_builtin_engines(), so some implementations get used
automatically instead of needing explicit application support.
[Steve Henson]
*) Add support for TLS key exporter as described in RFC5705.
[Robin Seggelmann <seggelmann@fh-muenster.de>, Steve Henson]
This is still somewhat experimental. Tested between 2 similar boxes
so far. There is much potential for performance improvement. For now,
I've changed the gmac code to accept any data alignment, as the "char *"
pointer suggests. As the code is practically used, 32-bit alignment
can be assumed, at the cost of data copies. I don't know whether
bytewise access or copies are worse performance-wise. For efficient
implementations using SSE2 instructions on x86, even stricter
alignment requirements might arise.
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.
sun2 port to proceed beyond trying and failing to build Heimdal.
This is done by:
1) Stop pretending that libipc is a separate library, and instead
build it as part of libkrb5. The version map for libkrb5 needed
to be updated to expose the required symbols from libipc.
2) The lexer in libhx509 needs to use its own prefix, so that the
resulting library can be statically linked with a lexer which
uses the default prefix. This was hidden because libhx509's
version map file (which is only used for the shared libs) hid
away the lexer symbols. Some defines needed tweaking as well
to restore buildability.
3) Excplicitly mention all the required libraries in LDADD+= and
make sure DPADD is set to correspond. This allows static linking;
earlier this relied on shared library dependencies to have all the
libs pulled in. In the process, convert to single-line LDADD+=
and DPADD+= settings. Use Makefile.inc for the common libraries
to the extent possible.
Successfully built from scratch for i386 and sun2 several times,
and for lots of other ports as well.
Discussed with elric@ and christos@.
