changes; bz#1891 reported by jchadima AT redhat.com; ok dtucker@
- (djm) [aclocal.m4 configure.ac] since gcc-4.x ignores all -Wno-options
options, we should corresponding -W-option when trying to determine
whether it is accepted. Also includes a warning fix on the program
fragment uses (bad main() return type).

- djm@cvs.openbsd.org 2011/05/08 12:52:01
[PROTOCOL.mux clientloop.c clientloop.h mux.c]
improve our behaviour when TTY allocation fails: if we are in
RequestTTY=auto mode (the default), then do not treat at TTY
allocation error as fatal but rather just restore the local TTY
to cooked mode and continue. This is more graceful on devices that
never allocate TTYs.
If RequestTTY is set to "yes" or "force", then failure to allocate
a TTY is fatal.

Add -A option. For each of the key types (rsa1, rsa, dsa and ecdsa)
for which host keys do not exist, generate the host keys with the
default key file path, an empty passphrase, default bits for the key
type, and default comment. This will be used by /etc/rc to generate

20110221
- (dtucker) [contrib/cygwin/ssh-host-config] From Corinna: revamp of the
Cygwin-specific service installer script ssh-host-config. The actual
functionality is the same, the revisited version is just more
exact when it comes to check for problems which disallow to run
certain aspects of the script. So, part of this script and the also
rearranged service helper script library "csih" is to check if all
the tools required to run the script are available on the system.
The new script also is more thorough to inform the user why the
script failed. Patch from vinschen at redhat com.

release testing (random crashes and failure to load ECC keys).
ok dtucker@

- (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

ECDH/ECDSA compliance fix: these methods vary the hash function they use
(SHA256/384/512) depending on the length of the curve in use. The previous
code incorrectly used SHA256 in all cases.
This fix will cause authentication failure when using 384 or 521-bit curve
keys if one peer hasn't been upgraded and the other has. (256-bit curve
keys work ok). In particular you may need to specify HostkeyAlgorithms
when connecting to a server that has not been upgraded from an upgraded
client.

Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
better performance than plain DH and DSA at the same equivalent symmetric
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).
Certificate host and user keys using the new ECDSA key types are supported.
Note that this code has not been tested for interoperability and may be
subject to change.

reopen stdin/stdout to /dev/null when forking for ControlPersist.
prevents tools that fork and run a captive ssh for communication from
failing to exit when the ssh completes while they wait for these fds to
close. The inherited fds may persist arbitrarily long if a background
mux master has been started by ControlPersist. cvs and scp were effected
by this.

[channels.c]
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.
