[sshconnect2.c sshd.c sshd_config sshd_config.5]
add a new compression method that delays compression until the user
has been authenticated successfully and set compression to 'delayed'
for sshd.
this breaks older openssh clients (< 3.5) if they insist on
compression, so you have to re-enable compression in sshd_config.

Fix a number of X11 forwarding channel leaks:
1. Refuse multiple X11 forwarding requests on the same session
2. Clean up all listeners after a single_connection X11 forward, not just
the one that made the single connection
3. Destroy X11 listeners when the session owning them goes away

use __sentinel__ attribute; ok deraadt@ djm@ markus@
- (dtucker) [configure.ac defines.h] Define __sentinel__ to nothing if the
compiler doesn't understand it to prevent warnings. If any mainstream
compiler versions acquire it we can test for those versions. Based on
discussion with djm@.
20050707
- dtucker [auth-krb5.c auth.h gss-serv-krb5.c] Move KRB5CCNAME generation for
the MIT Kerberos code path into a common function and expand mkstemp
template to be consistent with the rest of OpenSSH. From sxw at
inf.ed.ac.uk, ok djm@
- (dtucker) [auth-krb5.c] There's no guarantee that snprintf will set errno
in the case where the buffer is insufficient, so always return ENOMEM.
Also pointed out by sxw at inf.ed.ac.uk.
- (dtucker) [acconfig.h auth-krb5.c configure.ac gss-serv-krb5.c] Remove
calls to krb5_init_ets, which has not been required since krb-1.1.x and
most Kerberos versions no longer export in their public API. From sxw

[channels.c clientloop.c clientloop.h misc.c misc.h ssh.c ssh_config.5]
implement support for X11 and agent forwarding over multiplex slave
connections. Because of protocol limitations, the slave connections inherit
the master's DISPLAY and SSH_AUTH_SOCK rather than distinctly forwarding
their own.

Move compatibility code for supporting older OpenSSL versions to the
compat layer. Suggested by and "no objection" djm@
20050607
- (dtucker) [configure.ac] Continue the hunt for LLONG_MIN and LLONG_MAX:
in today's episode we attempt to coax it from limits.h where it may be
hiding, failing that we take the DIY approach. Tested by tim@
20050603
- (dtucker) [configure.ac] Only try gcc -std=gnu99 if LLONG_MAX isn't
defined, and check that it helps before keeping it in CFLAGS. Some old
gcc's don't set an error code when encountering an unknown value in -std.
Found and tested by tim@.
- (dtucker) [configure.ac] Point configure's reporting address at the
openssh-unix-dev list. ok tim@ djm@
20050602
- (tim) [configure.ac] Some platforms need sys/types.h for arpa/nameser.h.
Take AC_CHECK_HEADERS test out of ultrix section. It caused other platforms
to skip builtin standard includes tests. (first AC_CHECK_HEADERS test
must be run on all platforms) Add missing ;; to case statement. OK dtucker@
20050601
- (dtucker) [configure.ac] Look for _getshort and _getlong in
arpa/nameser.h.
- (dtucker) [configure.ac openbsd-compat/Makefile.in openbsd-compat/strtoll.c]
Add strtoll to the compat library, from OpenBSD.

[scp.c]
If copying multiple files to a target file (which normally fails, as it
must be a target directory), kill the spawned ssh child before exiting.
This stops it trying to authenticate and spewing lots of output.

- (dtucker) [openbsd-compat/port-aix.c] Bug #1046: AIX 5.3 expects the
argument to passwdexpired to be initialized to NULL. Suggested by tim@
While at it, initialize the other arguments to auth functions in case they
ever acquire this behaviour.
- (dtucker) [openbsd-compat/port-aix.c] Whitespace cleanups while there.
- (dtucker) [openbsd-compat/port-aix.c] Minor correction to debug message,
spotted by tim@.
20050528
- (dtucker) [configure.ac] For AC_CHECK_HEADERS() and AC_CHECK_FUNCS() have
one entry per line to make it easier to merge changes. ok djm@
- (dtucker) [configure.ac] strsep() may be defined in string.h, so check
for its presence and include it in the strsep check.
- (dtucker) [configure.ac] getpgrp may be defined in unistd.h, so check for
its presence before doing AC_FUNC_GETPGRP.
- (dtucker) [configure.ac] Merge HP-UX blocks into a common block with minor
version-specific variations as required.
- (dtucker) [openbsd-compat/port-aix.h] Use the HAVE_DECL_* definitions as
per the autoconf man page. Configure should always define them but it
doesn't hurt to check.
20050527

David Leach; ok dtucker@

[atomicio.c atomicio.h authfd.c monitor_wrap.c msg.c scp.c sftp-client.c]
[ssh-keyscan.c sshconnect.c]
Switch atomicio to use a simpler interface; it now returns a size_t
(containing number of bytes read/written), and indicates error by
returning 0. EOF is signalled by errno==EPIPE.
Typical use now becomes:
if (atomicio(read, ..., len) != len)
err(1,"read");
