Fix a harmless bug when opting against publishing a relay descriptor
because DisableNetwork is set.

Fixes bug 7464; bugfix on 0.2.3.9-alpha.

It broke linking on tor-resolve.c, and it's not actually sanitizing
anything sensitive.  Fix for bug 7420; bug not on ony released Tor.

Apparently some compilers like to eliminate memset() operations on
data that's about to go out-of-scope.  I've gone with the safest
possible replacement, which might be a bit slow.  I don't think this
is critical path in any way that will affect performance, but if it
is, we can work on that in 0.2.4.

Fixes bug 7352.

If we completed the handshake for the v2 link protocol but wound up
negotiating the wong protocol version, we'd become so confused about
what part of the handshake we were in that we'd promptly die with an
assertion.

This is a fix for CVE-2012-2250; it's a bugfix on 0.2.3.6-alpha.
All servers running that version or later should really upgrade.

Bug and fix from "some guy from France."  I tweaked his code slightly
to make it log the IP of the offending node.

The implementation we added has a tendency to crash with lists of 0 or
one element.  That can happen if we get a consensus vote, v2
consensus, consensus, or geoip file with 0 or 1 element.  There's a
DOS opportunity there that authorities could exploit against one
another, and which an evil v2 authority could exploit against anything
downloading v2 directory information..

This fix is minimalistic: It just adds a special-case for 0- and
1-element lists.  For 0.2.4 (the current alpha series) we'll want a
better patch.

This is bug 7191; it's a fix on 0.2.0.10-alpha.

Clients now consider the ClientRejectInternalAddresses config option
when using a microdescriptor consensus stanza to decide whether
an exit relay would allow exiting to an internal address. Fixes
bug 7190; bugfix on 0.2.3.1-alpha.

Our implementation of parse_short_policy was screwed up: it would
ignore the last character of every short policy.  Obviously, that's
broken.

This patch fixes the busted behavior, and adds a bunch of unit tests
to make sure the rest of that function is okay.

Fixes bug 7192; fix on 0.2.3.1-alpha.

OpenSSL 1.0.0 added an implementation of TLS session tickets, a
"feature" that let session resumption occur without server-side state
by giving clients an encrypted "ticket" that the client could present
later to get the session going again with the same keys as before.
OpenSSL was giving the keys to decrypt these tickets the lifetime of
the SSL contexts, which would have been terrible for PFS if we had
long-lived SSL contexts.  Fortunately, we don't.  Still, it's pretty
bad.  We should also drop these, since our use of the extension stands
out with our non-use of session cacheing.

Found by nextgens. Bugfix on all versions of Tor when built with
openssl 1.0.0 or later.  Fixes bug 7139.

Failure to do so left us open to a remotely triggerable assertion
failure. Fixes CVE-2012-2249; bugfix on 0.2.3.6-alpha. Reported by
"some guy from France".

We should still make sure mlp approves it.
