8743080a28 Disable TLS Session Tickets, which we were apparently getting for free
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.

3d8b73db55 Discard extraneous renegotiation attempts in the v3 link protocol
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".

This patch is a forward-port to 0.2.4, to work with the new channel
logic.

4164f481c8 Remove changes/bug7129
Our convention is that we use the changelog to note release-to-release
changes; we don't need to add changelog entries for bugs that didn't
appear in any released version of Tor.  (By convention, we sometimes
say "this bug does not appear in any released version of Tor" or words
to that effect in the commit message so that when Roger goes to make
sure the changelog is right, he knows not to expect a changelog entry
for that part.)

b555388dac Add a copy of OpenBSD's sys/queue.h as tor_queue.h
There are as many divergent implementations of sys/queue.h as there
are operating systems shipping it, it would seem.  They have some code
in common, but have drifted apart, and have added other stuff named
differently.  So I'm taking a relatively sane one, and hoping for the
best.

I'm taking OpenBSD's in particular because of the lack of external
dependencies, the presence of a CIRCLEQ (we could use one of those in
places), and the liberal licensing terms.

I'm naming the file tor_queue.h, since historically we've run into
trouble having headers with the same names as system headers (log.h,
for example.)

The conflict was trivial, since no line of code actually changed in
both branches: There was a fmt_addr() that turned into fmt_addrport()
in bug7011, and a "if (!n_conn)" that turned into "if (!n_chan)" in
master.

ce553d4982 Have node_get_pref_orport() return an IPv6 OR port when UseBridges is set.
We used to never return an IPv6 address unless ClientUseIPv6 was
set. We should allow clients running with bridges use IPv6 OR ports
even without setting ClientUseIPv6. Configuring an IPv6 address in a
Bridge line should imply that.

96d2a21683 Avoid sign-extending when computing rend auth type.
Right-shifting negative values has implementation-defined behavior.
On all the platforms we work on right now, the behavior is to
sign-extend the input.  That isn't what we wanted in

    auth_type_val = (descriptor_cookie_tmp[16] >> 4) + 1;

Fix for 6861; bugfix on 0.2.1.5-alpha; reported pseudonymously.

The broken behavior didn't actually hurt anything, I think, since the
only way to get sign-extension to happen would be to have the top bit
of descriptor_cookie_tmp[16] set, which would make the value of
descriptor_cookie_tmp[16] >> 4 somewhere between 0b11111111 and
0b11111000 (that is, between -1 and -8).  So auth_type_val would be
between -7 and 0.  And the immediate next line does:

    if (auth_type_val < 1 || auth_type_val > 2) {

So the incorrectly computed auth_type_val would be rejected as
invalid, just as a correctly computed auth_type_val would be.

Still, this stuff shouldn't sit around the codebase.

Our flag voting code needs to handle unrecognized flags, so it stores

5cbeb60805 Fix directory self-testing logic
When I removed version_supports_begindir, I accidentally removed the
mechanism we had been using to make a directory cache self-test its
directory port.  This caused bug 6815, which caused 6814 (both in
0.2.4.2-alpha).

To fix this bug, I'm replacing the "anonymized_connection" argument to
directory_initiate_command_* with an enumeration to say how indirectly
to connect to a directory server.  (I don't want to reinstate the
"version_supports_begindir" argument as "begindir_ok" or anything --
these functions already take too many arguments.)

For safety, I made sure that passing 0 and 1 for 'indirection' gives
the same result as you would have gotten before -- just in case I
missed any 0s or 1s.
