-     [ssh_config.5]
-     mention that ProxyCommand is executed using shell "exec" to avoid
-     a lingering process; bz#1977
-   - djm@cvs.openbsd.org 2014/07/09 01:45:10
-     [sftp.c]
-     more useful error message when GLOB_NOSPACE occurs;
-     bz#2254, patch from Orion Poplawski
-   - djm@cvs.openbsd.org 2014/07/09 03:02:15
-     [key.c]
-     downgrade more error() to debug() to better match what old authfile.c
-     did; suppresses spurious errors with hostbased authentication enabled
-   - djm@cvs.openbsd.org 2014/07/06 07:42:03
-     [multiplex.sh test-exec.sh]
-     add a hook to the cleanup() function to kill $SSH_PID if it is set
-     
-     use it to kill the mux master started in multiplex.sh (it was being left
-     around on fatal failures)
-   - djm@cvs.openbsd.org 2014/07/07 08:15:26
-     [multiplex.sh]

-     logic and forgot to remove...

-     [cipher-chachapoly.c]
-     Call chacha_ivsetup() immediately before chacha_encrypt_bytes() - this

-     [ssh-agent.c]
-     Only cleanup agent socket in the main agent process and not in any
-     subprocesses it may have started (e.g. forked askpass). Fixes
-     agent sockets being zapped when askpass processes fatal();

-   - djm@cvs.openbsd.org 2014/07/03 03:15:01
-     [ssh-add.c]

-   - djm@cvs.openbsd.org 2014/07/03 03:26:43
-     [digest-openssl.c]

-   - djm@cvs.openbsd.org 2014/07/03 03:34:09
-     [gss-serv.c session.c ssh-keygen.c]
-     standardise on NI_MAXHOST for gethostname() string lengths; about

-   - djm@cvs.openbsd.org 2014/07/03 03:47:27
-     [ssh-keygen.c]
-     When hashing or removing hosts using ssh-keygen, don't choke on

-     the mux master
-   - djm@cvs.openbsd.org 2014/07/03 06:39:19
-     [ssh.c ssh_config.5]
-     Add a %C escape sequence for LocalCommand and ControlPath that expands
-     to a unique identifer based on a has of the tuple of (local host,
-     remote user, hostname, port).
-     
-     Helps avoid exceeding sockaddr_un's miserly pathname limits for mux

-     [sshbuf-getput-crypto.c]
-     The ssh_get_bignum functions must accept the same range of bignums
-     the corresponding ssh_put_bignum functions create.  This fixes the
-     use of 16384-bit RSA keys (bug reported by Eivind Evensen).

+    Also, UpdateHostKeys=ask is incompatible with ControlPersist (no TTY
+    available to read the response) so disable UpdateHostKeys if it is in
+    ask mode and ControlPersist is active (and document this)

+    make the signature fuzzing test much more rigorous:
+     ensure that the fuzzed input cases do not match the original (using new

+     each case

+
+    upstream commit
+    
+    add a fuzz_matches_original() function to the fuzzer to
+     detect fuzz cases that are identical to the original data. Hacky
+     implementation, but very useful when you need the fuzz to be different, e.g.
+     when verifying signature

+    deprecate key_load_private_pem() and

+     not require pathnames to be specified (they weren't really used).
+    
+    Fixes a few other things en passant:
+    
+    Makes ed25519 keys work for hostbased authentication (ssh-keysign
+    previously used the PEM-only routines).
+    
+    Fixes key comment regression bz#2306: key pathnames were being lost as
+    comment fields.

+    avoid left shift overflow in reallocarray.
+    
+    Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting
+    1UL 32-bits to the left causes an overflow. This replaces the constant 1UL with
+    (size_t)1 so that we get the correct constant size for the platform.

+    discussed with tedu@ & deraadt@

+         bz#2147: fix multiple remote forwardings with dynamically assigned
+         listen ports. In the s->c message to open the channel we were sending
+         zero (the magic number to request a dynamic port) instead of the actual
+         listen port. The client therefore had no way of discriminating between
+         them.

+         to fully-qualified ones for host key matching.
+         This is particularly useful for host certificates, which would otherwise
+         need to list unqualified names alongside fully-qualified ones (and this
+         causes a number of problems).

+         Split the regress log into 3 parts: the debug output from ssh, the debug
+         log from sshd and the output from the client command (ssh, scp or sftp).
+         Somewhat functional now, will become more useful when ssh/sshd -E is added.

+        string          "hostkeys-00@openssh.com"
+        string[]        hostkeys
+
+Upon receiving this message, a client should check which of the
+supplied host keys are present in known_hosts. For keys that are
+not present, it should send a "hostkeys-prove@openssh.com" message
+to request the server prove ownership of the private half of the
+key.

+        char            1 /* want-reply */
+        string[]        hostkeys
+
+When a server receives this message, it should generate a signature
+using each requested key over the following:
+
+        string          "hostkeys-prove-00@openssh.com"
+        string          session identifier
+        string          hostkey
+
+These signatures should be included in the reply, in the order matching
+the hostkeys in the request:
+
+        byte            SSH_MSG_REQUEST_SUCCESS
+        string[]        signatures
+
+When the client receives this reply (and not a failure), it should
+validate the signatures and may update its known_hosts file, adding keys
+that it has not seen before and deleting keys for the server host that
+are no longer offered.
+
+These extensions let a client learn key types that it had not previously
+encountered, thereby allowing it to potentially upgrade from weaker
+key algorithms to better ones. It also supports graceful key rotation:
+a server may offer multiple keys of the same type for a period (to
+give clients an opportunity to learn them using this extension) before
+removing the deprecated key from those offered.

-X11 connections and arbitrary TCP/IP ports can also be forwarded over 
-the secure channel.

              Batch mode reads a series of commands from an input batchfile

      -6      Forces ssh-keyscan to use IPv6 addresses only.

-             Read hosts or ``addrlist namelist'' pairs from file, one per

      Match   Restricts the following declarations (up to the next Host or
              Match keyword) to be used only when the conditions following the
              Match keyword are satisfied.  Match conditions are specified
-             using one or more keyword/criteria pairs or the single token all
-             which matches all criteria.  The available keywords are: exec,
-             host, originalhost, user, and localuser.
-
-             The exec keyword executes the specified command under the user's
-             shell.  If the command returns a zero exit status then the
-             condition is considered true.  Commands containing whitespace
-             characters must be quoted.  The following character sequences in
-             the command will be expanded prior to execution: `%L' will be
-             substituted by the first component of the local host name, `%l'

-             name), `%h' will be substituted by the target host name, `%n'
-             will be substituted by the original target host name specified on
-             the command-line, `%p' the destination port, `%r' by the remote
-             login username, and `%u' by the username of the user running

+             exclamation mark (M-bM-^@M-^X!M-bM-^@M-^Y).
+
+             The canonical keywork matches only when the configuration file is
+             being re-parsed after hostname canonicalization (see the
+             CanonicalizeHostname option.)  This may be useful to specify
+             conditions that work with canonical host names only.  The exec
+             keyword executes the specified command under the user's shell.
+             If the command returns a zero exit status then the condition is
+             considered true.  Commands containing whitespace characters must
+             be quoted.  The following character sequences in the command will

+             by the username of the user running ssh(1).
 
              The other keywords' criteria must be single entries or comma-
              separated lists and may use the wildcard and negation operators
              described in the PATTERNS section.  The criteria for the host
              keyword are matched against the target hostname, after any
-             substitution by the Hostname option.  The originalhost keyword
-             matches against the hostname as it was specified on the command-
-             line.  The user keyword matches against the target username on
-             the remote host.  The localuser keyword matches against the name

+             the target username on the remote host.  The localuser keyword
+             matches against the name of the local user running ssh(1) (this
