7170c5b4f8 Limit uploaded directory documents to be 16M rather than 500K.
The directory authorities were refusing v3 consensus votes from
other authorities, since the votes are now 504K. Fixes bug 959;
bugfix on 0.0.2pre17 (where we raised it from 50K to 500K ;).

30ec1d1d50 Don't double-free successful_uploads.
When we used smartlist_free to free the list of succesful uploads
because we had succeeded in uploading everywhere, we did not actually
set the successful_uploads field to NULL, so later it would get freed
again in rend_service_descriptor_free.  Fix for bug 948; bug
introduced in 0.2.1.6-alpha.

26d83fc04c Add a simple locale-independent no-surprises sscanf replacement.
tor_sscanf() only handles %u and %s for now, which will make it
adequate to replace sscanf() for date/time/IP parsing.  We want this
to prevent attackers from constructing weirdly formed descriptors,
cells, addresses, HTTP responses, etc, that validate under some
locales but not others.

9f8d095e0f Add and use set/get_uint64 on onion tags. [bug 604; backportable]
It seems that 64-bit Sparc Solaris demands 64-bit-aligned access to
uint64_t, but does not 64-bit-align the stack-allocated char array we
use for cpuworker tags.  So this patch adds a set/get_uint64 pair, and
uses them to access the conn_id field in the tag.

6f90f6f2a2 Retry circuits if the exit node is optional and nonexistant.
Previously, when we had the chosen_exit set but marked optional, and
we failed because we couldn't find an onion key for it, we'd just give
up on the circuit.  But what we really want to do is try again, without
the forced exit node.

Spotted by rovv.  Another case of bug 752.  I think this might be
unreachable in our current code, but proposal 158 could change that.

f78793879d Fix a race condition on nameserver reconfiguration.
This resolves bug 526, wherein we would crash if the following
events occurred in this order:
  A: We're an OR, and one of our nameservers goes down.
  B: We launch a probe to it to see if it's up again. (We do this hourly
     in steady-state.)
  C: Before the probe finishes, we reconfigure our nameservers,
     usually because we got a SIGHUP and the resolve.conf file changed.
  D: The probe reply comes back, or times out. (There is a five-second
     window for this, after B has happens).

IOW, if one of our nameservers is down and our nameserver
configuration has changed, there were 5 seconds per hour where HUPing
the server was unsafe.

e06de61d84 Don't obsolete a very-new connection for having no circuits yet.
This fixes the last known case of bug 891, which could happen if two
hosts, A and B, disagree about how long a circuit has been open,
because of clock drift of some kind.  Host A would then mark the
connection as is_bad_for_new_circs when it got too old and open a new
connection.  In between when B receives a NETINFO cell on the new
conn, and when B receives a conn cell on the new circuit, the new
circuit will seem worse to B than the old one, and so B will mark it
as is_bad_for_new_circs in the second or third loop of
connection_or_group_set_badness().

Bugfix on 0.1.1.13-alpha.  Bug found by rovv.

Not a backport candidate: the bug is too obscure and the fix too tricky.

743c6c8277 OpenBSD malloc.h believes that you should be able to detect headers with autoconf, or build without warnings, but not both. So never include malloc.h on OpenBSD. Backport candidate.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.
