64f393d56f Only send netinfo clock_skew to controller if an authority told us so
We were triggering a CLOCK_SKEW controller status event whenever
we connect via the v2 connection protocol to any relay that has
a wrong clock. Instead, we should only inform the controller when
it's a trusted authority that claims our clock is wrong. Bugfix
on 0.2.0.20-rc; starts to fix bug 1074. Reported by SwissTorExit.

8c29b7920a Add some fixes after discussion with Nick.
- Refactor geoip.c by moving duplicate code into rotate_request_period().
- Don't leak memory when cleaning up cell queues.
- Make sure that exit_(streams|bytes_(read|written)) are initialized in all
  places accessing these arrays.
- Read only the last block from *stats files and ensure that its timestamp
  is not more than 25 hours in the past and not more than 1 hour in the
  future.
- Stop truncating the last character when reading *stats files.

The only thing that's left now is to avoid reading whole *stats files into
memory.

9d11827780 Fix a rare infinite-recursion bug when shutting down.
Once we had called log_free_all(), anything that tried to log a
message (like a failed tor_assert()) would fail like this:

   1. The logging call eventually invokes the _log() function.
   2. _log() calls tor_mutex_lock(log_mutex).
   3. tor_mutex_lock(m) calls tor_assert(m).
   4. Since we freed the log_mutex, tor_assert() fails, and tries to
      log its failure.
   5. GOTO 1.

Now we allocate the mutex statically, and never destroy it on
shutdown.

Bugfix on 0.2.0.16-alpha, which introduced the log mutex.

This bug was found by Matt Edman.

d0c212995a Add a SHA256 implementation for platforms that lack it.
(This would be everywhere running OpenSSL 0.9.7x and earlier, including
all current Macintosh users.)

The code is based on Tom St Denis's LibTomCrypt implementation,
modified to be way less general and use Tor's existing facilities.  I
picked this one because it was pretty fast and pretty free, and
because Python uses it too.

2b63fa40e8 three hacks to workaround bug 1038
The problem is that clients and hidden services are receiving
relay_early cells, and they tear down the circuit.

Hack #1 is for rendezvous points to rewrite relay_early cells to
relay cells. That way there are never any incoming relay_early cells.

Hack #2 is for clients and hidden services to never send a relay_early
cell on an established rendezvous circuit. That works around rendezvous
points that haven't upgraded yet.

Hack #3 is for clients and hidden services to not tear down the circuit
when they receive an inbound relay_early cell. We already refuse extend
cells at clients.

7b716878cb Fix dirreq and cell stats on 32-bit architectures.
When determining how long directory requests take or how long cells spend
in queues, we were comparing timestamps on microsecond detail only to
convert results to second or millisecond detail later on. But on 32-bit
architectures this means that 2^31 microseconds only cover time
differences of up to 36 minutes. Instead, compare timestamps on
millisecond detail.

- Rename output file from geoip-stats to dirreq-stats.

3e6bb050dd Make an attempt to fix bug 1024.
The internal error "could not find intro key" occurs when we want to send
an INTRODUCE1 cell over a recently finished introduction circuit and think
we built the introduction circuit with a v2 hidden service descriptor, but
cannot find the introduction key in our descriptor.

My first guess how we can end up in this situation is that we are wrong in
thinking that we built the introduction circuit based on a v2 hidden
service descriptor. This patch checks if we have a v0 descriptor, too, and
uses that instead.

690db1331d another minor patch to add to 0.2.1.x
o Minor features:
    - If we're a relay and we change our IP address, be more verbose
      about the reason that made us change. Should help track down
      further bugs for relays on dynamic IP addresses.

e7bc189f7c the third piece of bug 969 fixing
when we write out our stability info, detect relays that have slipped
through the cracks. log about them and correct the problem.

if we continue to see a lot of these over time, it means there's another
spot where relays fall out of the routerlist without being marked as
unreachable.

we never generate large DNS replies.

fa89c9f086 Flush long replies over control port on QUIT
Marks the control port connection for flushing before closing when
the QUIT command is issued. This allows a QUIT to be issued during
a long reply over the control port, flushing the reply and then
closing the connection. Fixes bug 1015.

1aaab8288d Clients now use bandwidth values in the consensus
rather than the bandwidth values in each relay descriptor. This approach
opens the door to more accurate bandwidth estimates once the directory
authorities start doing active measurements. Implements more of proposal
141.

262455527a Serve DirPortFrontPage even if the write bucket is low.
arma's rationale: "I think this is a bug, since people intentionally
set DirPortFrontPage, so they really do want their relay to serve that
page when it's asked for. Having it appear only sometimes (or roughly
never in Sebastian's case) makes it way less useful."

Fixes bug 1013; bugfix on 0.2.1.8-alpha.

298dc95dfd tor-resolve: Don't automatically refuse .onion addresses.
If the Tor is running with AutomapHostsOnResolve set, it _is_
reasonable to do a DNS lookup on a .onion address.  So instead we make
tor-resolve willing to try to resolve anything.  Only if Tor refuses
to resolve it do we suggest to the user that resolving a .onion
address may not work.

Fix for bug 1005.

1e709c79d1 Isolate Libevent API dependency to just main.c and dns.c in src/or.

connection_watch_events interface for no very good reason.

e5b88dc83f Update Tor to use Libevent 2.0 APIs when available.
This patch adds a new compat_libevent.[ch] set of files, and moves our
Libevent compatibility and utilitity functions there.  We build them
into a separate .a so that nothing else in src/commmon depends on
Libevent (partially fixing bug 507).

Also, do not use our own built-in evdns copy when we have Libevent
2.0, whose evdns is finally good enough (thus fixing Bug 920).
