   - djm@cvs.openbsd.org 2014/03/12 04:50:32
     [auth-bsdauth.c ssh-keygen.c]
     don't count on things that accept arguments by reference to clear
     things for us on error; most things do, but it's unsafe form.
   - djm@cvs.openbsd.org 2014/03/12 04:51:12
     [authfile.c]
     correct test that kdf name is not "none" or "bcrypt"
   - naddy@cvs.openbsd.org 2014/03/12 13:06:59

     [ssh-agent.c ssh-keygen.1 ssh-keygen.c]
     Improve usage() and documentation towards the standard form. 
     In particular, this line saves a lot of man page reading time.
       usage: ssh-keygen [-q] [-b bits] [-t dsa | ecdsa | ed25519 | rsa | rsa1]
                         [-N new_passphrase] [-C comment] [-f output_keyfile]

     [myproposal.h]
     trimm default proposals.
     
     This commit removes the weaker pre-SHA2 hashes, the broken ciphers
     (arcfour), and the broken modes (CBC) from the default configuration
     (the patch only changes the default, all the modes are still available
     for the config files).
     
     ok djm@, reminded by tedu@ & naddy@ and discussed with many
   - deraadt@cvs.openbsd.org 2014/03/26 17:16:26
     [myproposal.h]
     The current sharing of myproposal[] between both client and server code
     makes the previous diff highly unpallatable.  We want to go in that
     direction for the server, but not for the client.  Sigh.
     Brought up by naddy.
   - markus@cvs.openbsd.org 2014/03/27 23:01:27
     [myproposal.h ssh-keyscan.c sshconnect2.c sshd.c]

     [chacha.h cipher-chachapoly.h digest.h hmac.h kex.h kexc25519.c
     [misc.h poly1305.h ssh-pkcs11.c]
     use __bounded(...) attribute recently added to sys/cdefs.h instead of
     longform __attribute__(__bounded(...));
     
     for brevity and a warning free compilation with llvm/clang
   - tedu@cvs.openbsd.org 2014/03/26 19:58:37

     [ssh-keygen.1]
     the text for the -K option was inserted in the wrong place in -r1.108;
     fix From: Matthew Clarke
   - djm@cvs.openbsd.org 2014/04/01 02:05:27
     [ssh-keysign.c]
     include fingerprint of key not found
     use arc4random_buf() instead of loop+arc4random()
   - djm@cvs.openbsd.org 2014/04/01 03:34:10
     [sshconnect.c]
     When using VerifyHostKeyDNS with a DNSSEC resolver, down-convert any
     certificate keys to plain keys and attempt SSHFP resolution.
     
     Prevents a server from skipping SSHFP lookup and forcing a new-hostkey
     dialog by offering only certificate keys.

     [readconf.c readconf.h ssh.c ssh_config.5]
     reparse ssh_config and ~/.ssh/config if hostname canonicalisation changes

 - (djm) [configure.ac atomicio.c] Kludge around NetBSD offering

     [cipher.c cipher.h kex.c kex.h kexgexc.c]
     Add a special case for the DH group size for 3des-cbc, which has an
     effective strength much lower than the key size.  This causes problems
     with some cryptlib implementations, which don't support group sizes larger
     than 4k but also don't use the largest group size it does support as
     specified in the RFC.  Based on a patch from Petr Lautrbach at Redhat,
     reduced by me with input from Markus.  ok djm@ markus@

  - (djm) [configure.ac sandbox-capsicum.c sandbox-rlimit.c] Disable
    RLIMIT_NOFILE pseudo-sandbox on FreeBSD. In some configurations,
    libc will attempt to open additional file descriptors for crypto
    offload and crash if they cannot be opened.
 - (djm) [configure.ac] correct AC_DEFINE for previous.

20140125
 - (djm) [configure.ac] Fix detection of capsicum sandbox on FreeBSD
 - (djm) [configure.ac] Do not attempt to use capsicum sandbox unless
   sys/capability.h exists and cap_rights_limit is in libc. Fixes
   build on FreeBSD9x which provides the header but not the libc
   support.
 - (djm) [configure.ac] autoconf sets finds to 'yes' not '1', so test
   against the correct thing.

20140124
 - (djm) [Makefile.in regress/scp-ssh-wrapper.sh regress/scp.sh] Make
   the scp regress test actually test the built scp rather than the one
   in $PATH. ok dtucker@

20140123
 - (tim) [session.c] Improve error reporting on set_id().
 - (dtucker) [configure.ac] NetBSD's (and FreeBSD's) strnvis is gratuitously
   incompatible with OpenBSD's despite post-dating it by more than a decade.
   Declare it as broken, and document FreeBSD's as the same.  ok djm@

20140122
 - (djm) [openbsd-compat/setproctitle.c] Don't fail to compile if a
   platform that is expected to use the reuse-argv style setproctitle
   hack surprises us by providing a setproctitle in libc; ok dtucker
 - (djm) [configure.ac] Unless specifically requested, only attempt
   to build Position Independent Executables on gcc >= 4.x; ok dtucker
 - (djm) [configure.ac aclocal.m4] More tests to detect fallout from
   platform hardening options: include some long long int arithmatic
   to detect missing support functions for -ftrapv in libgcc and
   equivalents, actually test linking when -ftrapv is supplied and
   set either both -pie/-fPIE or neither. feedback and ok dtucker@

20140121
 - (dtucker) [configure.ac] Make PIE a configure-time option which defaults
   to on platforms where it's known to be reliably detected and off elsewhere.
   Works around platforms such as FreeBSD 9.1 where it does not interop with
   -ftrapv (it seems to work but fails when trying to link ssh).  ok djm@
 - (dtucker) [aclocal.m4] Differentiate between compile-time and link-time
   tests in the configure output.  ok djm.
 - (tim) [platform.c session.c] Fix bug affecting SVR5 platforms introduced
   with sftp chroot support. Move set_id call after chroot.
 - (djm) [aclocal.m4] Flesh out the code run in the OSSH_CHECK_CFLAG_COMPILE
   and OSSH_CHECK_LDFLAG_LINK tests to give them a better chance of
   detecting toolchain-related problems; ok dtucker

20140120
 - (dtucker) [gss-serv-krb5.c] Fall back to krb5_cc_gen_new if the Kerberos
   implementation does not have krb5_cc_new_unique, similar to what we do
   in auth-krb5.c.
 - (djm) [regress/cert-hostkey.sh] Fix regress failure on platforms that
   skip one or more key types (e.g. RHEL/CentOS 6.5); ok dtucker@

 - (dtucker) [uidswap.c] Prevent unused variable warnings on Cygwin.  Patch
   from vinschen at redhat.com
 - (dtucker) [openbsd-compat/bsd-cygwin_util.h] Add missing function
   declarations that stopped being included when we stopped including
   <windows.h> from openbsd-compat/bsd-cygwin_util.h.  Patch from vinschen at
   redhat.com.
 - (dtucker) [configure.ac] On Cygwin the getopt variables (like optargs,
   optind) are defined in getopt.h already.  Unfortunately they are defined as
   "declspec(dllimport)" for historical reasons, because the GNU linker didn't
   allow auto-import on PE/COFF targets way back when.  The problem is the
   dllexport attributes collide with the definitions in the various source
   files in OpenSSH, which obviousy define the variables without
   declspec(dllimport).  The least intrusive way to get rid of these warnings
   is to disable warnings for GCC compiler attributes when building on Cygwin.
   Patch from vinschen at redhat.com.
 - (dtucker) [sandbox-capsicum.c] Correct some error messages and make the

 - (dtucker) [configure.ac openbsd-compat/xcrypt.c] bz#2112: fall back to
   using openssl's DES_crypt function on platorms that don't have a native
   one, eg Android.  Based on a patch from Nathan Osman.
 - (dtucker) [configure.ac defines.h] Test for fd_mask, howmany and NFDBITS
   rather than trying to enumerate the plaforms that don't have them.
   Based on a patch from Nathan Osman, with help from tim@.

     Standardise logging of supplemental information during userauth. Keys
     and ruser is now logged in the auth success/failure message alongside
     the local username, remote host/port and protocol in use. Certificates
     contents and CA are logged too.
