   - djm@cvs.openbsd.org 2011/02/04 00:44:21
     [key.c]
     fix uninitialised nonce variable; reported by Mateusz Kocielski
   - djm@cvs.openbsd.org 2011/02/04 00:44:43
     [version.h]
     openssh-5.8
 - (djm) [README contrib/caldera/openssh.spec contrib/redhat/openssh.spec]
   [contrib/suse/openssh.spec] update versions in docs and spec files.
 - Release OpenSSH 5.8p1

20110128
 - (djm) [openbsd-compat/port-linux.c] Check whether SELinux is enabled
   before attempting setfscreatecon(). Check whether matchpathcon()
   succeeded before using its result. Patch from cjwatson AT debian.org;
   bz#1851

20110125
 - (djm) [configure.ac Makefile.in ssh.c openbsd-compat/port-linux.c
   openbsd-compat/port-linux.h] Move SELinux-specific code from ssh.c to
   port-linux.c to avoid compilation errors. Add -lselinux to ssh when
   building with SELinux support to avoid linking failure; report from
   amk AT spamfence.net; ok dtucker

20110122
 - (dtucker) [configure.ac openbsd-compat/openssl-compat.{c,h}] Add
   RSA_get_default_method() for the benefit of openssl versions that don't
   have it (at least openssl-engine-0.9.6b).  Found and tested by Kevin Brott,
   ok djm@.
 - OpenBSD CVS Sync
   - djm@cvs.openbsd.org 2011/01/22 09:18:53
     [version.h]
     crank to OpenSSH-5.7

   [contrib/suse/openssh.spec] update versions in docs and spec files.
 - (djm) Release 5.7p1

20110119
 - (tim) [contrib/caldera/openssh.spec] Use CFLAGS from Makefile instead
   of RPM so build completes. Signatures were changed to .asc since 4.1p1.
 - (djm) [configure.ac] Disable ECC on OpenSSL <0.9.8g. Releases prior to
   0.9.8 lacked it, and 0.9.8a through 0.9.8d have proven buggy in pre-
   release testing (random crashes and failure to load ECC keys).
   ok dtucker@

20110117
 - (djm) [regress/Makefile] use $TEST_SSH_KEYGEN instead of the one in
   $PATH, fix cleanup of droppings; reported by openssh AT

   its unique snowflake of a gdb error to the ones we look for.
 - (djm) [regress/agent-getpeereid.sh] leave stdout attached when running
   ssh-add to avoid $SUDO failures on Linux
 - (dtucker) [openbsd-compat/port-linux.c] Bug #1838: Add support for the new
   Linux OOM-killer magic values that changed in 2.6.36 kernels, with fallback
   to the old values.  Feedback from vapier at gentoo org and djm, ok djm.
 - (djm) [configure.ac regress/agent-getpeereid.sh regress/multiplex.sh]
   [regress/sftp-glob.sh regress/test-exec.sh] Rework how feature tests are
   disabled on platforms that do not support them; add a "config_defined()"
   shell function that greps for defines in config.h and use them to decide
   on feature tests.
   Convert a couple of existing grep's over config.h to use the new function
   Add a define "FILESYSTEM_NO_BACKSLASH" for filesystem that can't represent
   backslash characters in filenames, enable it for Cygwin and use it to turn
   of tests for quotes backslashes in sftp-glob.sh.
   based on discussion with vinschen AT redhat.com and dtucker@; ok dtucker@
 - (tim) [regress/agent-getpeereid.sh] shell portability fix.
 - (dtucker) [openbsd-compat/port-linux.c] Fix minor bug caught by -Werror on

     [clientloop.c]
     Use atomicio when flushing protocol 1 std{out,err} buffers at
     session close. This was a latent bug exposed by setting a SIGCHLD
     handler and spotted by kevin.brott AT gmail.com; ok dtucker@
   - djm@cvs.openbsd.org 2011/01/16 11:50:36
     [sshconnect.c]
     reset the SIGPIPE handler when forking to execute child processes;
     ok dtucker@
   - djm@cvs.openbsd.org 2011/01/16 12:05:59
     [clientloop.c]
     a couple more tweaks to the post-close protocol 1 stderr/stdout flush:

     [PROTOCOL.mux]
     correct protocol names and add a couple of missing protocol number
     defines; patch from bert.wesarg AT googlemail.com
 - (djm) [Makefile.in] Use shell test to disable ecdsa key generating in
   host-key-force target rather than a substitution that is replaced with a
   comment so that the Makefile.in is still a syntactically valid Makefile
   (useful to run the distprep target)
 - (tim) [regress/cert-hostkey.sh] Typo. Missing $ on variable name.
 - (tim) [regress/cert-hostkey.sh] Add missing TEST_SSH_ECC guard around some
   ecdsa bits.

 - (tim) [Makefile.in configure.ac opensshd.init.in] Add support for generating
   ecdsa keys. ok djm.
 - (djm) [entropy.c] cast OPENSSL_VERSION_NUMBER to u_long to avoid
   gcc warning on platforms where it defaults to int
 - (djm) [regress/Makefile] add a few more generated files to the clean
   target
 - (djm) [myproposal.h] Fix reversed OPENSSL_VERSION_NUMBER test and bad
   #define that was causing diffie-hellman-group-exchange-sha256 to be
   incorrectly disabled
 - (djm) [regress/kextype.sh] Testing diffie-hellman-group-exchange-sha256
   should not depend on ECC support

     Idea from a similar NetBSD change, original problem reported by jasper@.
     ok millert tedu jasper
   - djm@cvs.openbsd.org 2011/01/12 01:53:14
     avoid some integer overflows mostly with GLOB_APPEND and GLOB_DOOFFS
     and sanity check arguments (these will be unnecessary when we switch
     struct glob members from being type into to size_t in the future);
     "looks ok" tedu@ feedback guenther@
 - (djm) [configure.ac] Turn on -Wno-unused-result for gcc >= 4.4 to avoid
   silly warnings on write() calls we don't care succeed or not.
 - (djm) [configure.ac] Fix broken test for gcc >= 4.4 with per-compiler
   flag tests that don't depend on gcc version at all; suggested by and
   ok dtucker@

     recently
   - djm@cvs.openbsd.org 2011/01/11 06:13:10
     [clientloop.c ssh-keygen.c sshd.c]
     some unsigned long long casts that make things a bit easier for
     portable without resorting to dropping PRIu64 formats everywhere

     the the askpass child's exit status. Correct test for exit status/signal to
     account for waitpid() failure; with claudio@ ok claudio@ markus@
   - djm@cvs.openbsd.org 2010/12/24 21:41:48
     [auth-options.c]

     [ssh-keyscan.c]
     handle ecdsa-sha2 with various key lengths; hint and ok djm@

20110104

20110103
 - (djm) [Makefile.in] revert local hack I didn't intend to commit

20110102
 - (djm) [loginrec.c] Fix some fd leaks on error paths. ok dtucker
 - (djm) [configure.ac] Check whether libdes is needed when building
   with Heimdal krb5 support. On OpenBSD this library no longer exists,
   so linking it unconditionally causes a build failure; ok dtucker

     [schnorr.c]
     check that g^x^q === 1 mod p; recommended by JPAKE author Feng Hao
     (this code is still disabled, but apprently people are treating it as
     a reference implementation)
   - djm@cvs.openbsd.org 2010/12/03 23:55:27
     [auth-rsa.c]
     move check for revoked keys to run earlier (in auth_rsa_key_allowed)

     [sftp-server.c sftp.1 sftp-client.h sftp.c PROTOCOL sftp-client.c]
     add a protocol extension to support a hard link operation. It is
     available through the "ln" command in the client. The old "ln"
     behaviour of creating a symlink is available using its "-s" option
     or through the preexisting "symlink" command; based on a patch from
     miklos AT szeredi.hu in bz#1555; ok markus@

   shims for the new, non-deprecated OpenSSL key generation functions for
   platforms that don't have the new interfaces.

     [authfile.c]
     Refactor internals of private key loading and saving to work on memory
     buffers rather than directly on files. This will make a few things
     easier to do in the future; ok markus@
   - djm@cvs.openbsd.org 2010/11/23 02:35:50

     [channels.c]
     remove a debug() that pollutes stderr on client connecting to a server
     in debug mode (channel_close_fds is called transitively from the session
     code post-fork); bz#1719, ok dtucker
   - djm@cvs.openbsd.org 2010/11/25 04:10:09

     [sshconnect.h sshconnect2.c]
     automatically order the hostkeys requested by the client based on
     which hostkeys are already recorded in known_hosts. This avoids
     hostkey warnings when connecting to servers with new ECDSA keys
     that are preferred by default; with markus@

20101111
 - (djm) [servconf.c ssh-add.c ssh-keygen.c] don't look for ECDSA keys on
   platforms that don't support ECC. Fixes some spurious warnings reported

   - djm@cvs.openbsd.org 2010/10/28 11:22:09
     [authfile.c key.c key.h ssh-keygen.c]
     fix a possible NULL deref on loading a corrupt ECDH key
     
     store ECDH group information in private keys files as "named groups"
     rather than as a set of explicit group parameters (by setting
     the OPENSSL_EC_NAMED_CURVE flag). This makes for shorter key files and
     retrieves the group's OpenSSL NID that we need for various things.

     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).

     Fix a trio of bugs in the local/remote window calculation for datagram
     data channels (i.e. TunnelForward):
     
     Calculate local_consumed correctly in channel_handle_wfd() by measuring
     the delta to buffer_len(c->output) from when we start to when we finish.
     The proximal problem here is that the output_filter we use in portable
     modified the length of the dequeued datagram (to futz with the headers
     for !OpenBSD).
     
     In channel_output_poll(), don't enqueue datagrams that won't fit in the
     peer's advertised packet size (highly unlikely to ever occur) or which
     won't fit in the peer's remaining window (more likely).
     
     In channel_input_data(), account for the 4-byte string header in
     datagram packets that we accept from the peer and enqueue in c->output.

     [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.
