e0deac8960 sk_address_is_local() failed to cope when presented with a Unix-domain socket.
This could cause Unix PuTTY to segfault when X forwarding over an SSH session
through a proxy.
(sk_getaddr() wouldn't cope either -- in that case, add an assertion to make it
more obvious; I don't think it should ever happen.)

3e6111243c r5080 didn't go far enough -- since 0.58, anyone on Unix who didn't previously
have default settings for "bell overload" mode will have inherited a twitchy
set of defaults where bells are disabled after 2ms and enabled after 5ms,
rather than 2s and 5s as intended. This error has probably propagated into some
people's saved sessions by now, but there's not much to be done.

bd5cec280a Add some hard-coded textual literal-IP representations of localhost to
sk_hostname_is_local(), to catch the case where we're doing something like X11
forwarding over SSH through a proxy, and we've thus disabled local lookup of
hostnames.
(I think this is what's behind the report in
<e9a86996-5dc2-4428-9b0c-c65693ca6351@m32g2000hsf.googlegroups.com>
in comp.security.ssh, although I'd like to know more of the circumstances.)

do this if the supplied buffer isn't big enough, which shouldn't lead to

db6ad48673 r8305 seems to have made Unix PuTTY rather over-keen on Unix-domain sockets;
unless a protocol is explicitly specified with "tcp/foovax:0", it assume a
Unix-domain socket, thus not allowing a remote display on a machine other than
the client.

81287fb7ad Bah, I've bumped into this often enough. Change one unsatisfactory cast for
another to shut up "warning: cast from pointer to integer of different size"
(and hence a -Werror compile failure) when compiling for Unix with DEBUG
defined on atreus (x86_64). Minimally checked that it doesn't introduce upset
elsewhere (i386).

cf3b45392d "Derek" reports that the DECSLPP report of window-size-in-pixels (CSI 14 t)
has width and height swapped. Since both a random xterm I have and
<http://invisible-island.net/xterm/ctlseqs/ctlseqs.txt> agree with him, I've
changed ours. (This stuff appears to originate in dtterm, but I can't check the
behaviour of that right now.)

While I'm here, the are-we-iconified report (CSI 11 t) looks to have the
wrong sense compared to the same sources, so swap that too.

(All this has been this way since it was originally implemented in r1414,
which doesn't cite a source. all-escapes is silent too.)

b892d451ee Jacob correctly points out that I accidentally lost a clearing of
s->gss_sndtok in r8326.  I'm not sure it was strictly necessary, since
even if there's no send token, gss_init_sec_context() is meant to explicitly
make it empty, but it wasn't an intentional change.

86c183f8e8 Mitigation for VU#958563: When using a CBC-mode server-to-client cipher
under SSH-2, don't risk looking at the length field of an incoming packet
until we've successfully MAC'ed the packet.

This requires a change to the MAC mechanics so that we can calculate MACs
incrementally, and output a MAC for the packet so far while still being
able to add more data to the packet later.

81dafd906e Change how we handle the Ssh_gss_buf type. Previously, we defined it
ourselves, but on Unix then assumed it was compatible with the system's
gss_buffer_desc, which wasn't the case on LP64 systems.  Now, on Unix
we make Ssh_gss_buf into an alias for gss_buffer_desc, though we keep
something similar to the existing behaviour on Windows.  This requires
renaming a couple of the fields in Ssh_gss_buf, and hence fixing all
the references.

Tested on Linux (MIT Kerberos) and Solaris.  Compiled on NetBSD (Heimdal).
Not tested on Windows because neither mingw32 nor winegcc worked out of the
box for me.  I think the Windows changes are all syntactic, though, so
if this compiles it should work no worse than before.

dc896b79af New option to allow use of the local OS username for login to the remote side
if we have no better ideas, with UI shamelessly stolen from Quest PuTTY.

Off by default, which effectively reverts the change to using the local
username by default that came in with GSSAPI support in r8138. Anyone wanting
seamless single sign-on will need to set the new option. (The previous
default behaviour was getting in the way in ad-hoc scenarios.)

Note that the PSCP and Unix-Plink behaviour of using the local username by
default have remained unchanged throughout; they are not affected by the new
option. Not sure if that's the Right Thing.

ca6fc3a4da Revamp of the local X11 connection code. We now parse X display
strings more rigorously, and then we look up the local X authority
data in .Xauthority _ourself_ rather than delegating to an external
xauth program. This is (negligibly) more efficient on Unix, assuming
I haven't got it wrong in some subtle way, but its major benefit is
that we can now support X authority lookups on Windows as well
provided the user points us at an appropriate X authority file in
the standard format. A new Windows-specific config option has been
added for this purpose.

0cef8a897d Avoid freeing the backend in notify_remote_exit(), since that's

backend pointer to still be valid on return. Instead, move all the

3a3abd211b In SSH packet logging mode, log SSH-2 packet sequence numbers, in
both directions. We had a bug report yesterday about a Cisco router
sending SSH2_MSG_UNIMPLEMENTED and it wasn't clear for which packet;
logging the sequence numbers should make such problems much easier
to diagnose.

(In fact this logging fix wouldn't have helped in yesterday's case,
because the router also didn't bother to fill in the sequence number
field in the SSH2_MSG_UNIMPLEMENTED packet! This is a precautionary
measure against the next one of these problems.)

6e2501be77 Move out of the SockAddr structure the mutable fields "ai" and
"curraddr", and turn "family" into a macro-derived property of the
other fields. The idea is that this renders SockAddrs immutable once
created, which should open up the possibility of duplicating and
reusing one without having to redo the actual DNS lookup.

I _hope_ I haven't broken anything. The new code architecture
contains several rather dubious-looking operations (namely the
arbitrary choice of the first returned address in functions like
sk_getaddr and sk_address_is_local - what if, for instance, a DNS
lookup returned a local and a non-local address?), but I think they
were functionally just as dubious beforehand and all this change has
done is to make them more obviously so to a reader.

a59c4e9486 sshrsa.c now obeys the RFC793 Robustness Principle when it comes to
the ordering of the primes in a fully specified RSA private key:
when the key format typically has p > q, it will always output p > q
but be willing to tolerate p < q on input. (Inspired by seeing an
OpenSSH-format key file in the wild which had p < q, which I've
never seen before; I suspect a third-party application incautiously
generating the format.)
