Bridges are not supposed to publish router descriptors to the directory
authorities. It defeats the point of bridges when they are included in the
public relay directory.
This patch puts out a warning and exits when the node is configured as
a bridge and to publish v1, v2, or v3 descriptors at the same time.
Also fixes part of bug 932.
This addresses the first part of bug 918. Users are now warned when
they try to use hibernation in combination with a port below 1024
when they're not on Windows. We don't want to die here, because
people might run Tor as root, use a capabilities system or some
other platform that will allow them to re-attach low ports.
Wording suggested by Marian
(Don't crash immediately if we have leftover chunks to free after
freeing chunks in a buffer freelist; instead log a debugging message
that might help.)
Now, when you call tor --digests, it dumps the SHA1 digest of each
source file that Tor was built with. We support both 'sha1sum' and
'openssl sha1'. If the user is building from a tarball and they
haven't edited anything, they don't need any program that calculates
SHA1. If they _have_ modified a file but they don't have a program to
calculate SHA1, we try to build so we do not output digests.
bytes (aka 20KB/s), to match our documentation. Also update
directory authorities so they always assign the Fast flag to relays
with 20KB/s of capacity. Now people running relays won't suddenly
find themselves not seeing any use, if the network gets faster
on average.

IP address changes: directory mirrors were mistakenly telling them
their old address if they asked via begin_dir, so they never got
an accurate answer about their new address, so they just vanished
after a day. Should fix bugs 827, 883, and 900 -- but alas, only
after every directory mirror has upgraded.

especially once more people upgrade, since relays that have been
a guard for a long time are currently overloaded.

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 ;).

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.
svn:r19073
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.

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.

It turns out that we weren't updating the _ExcludeExitNodesUnion set's
country numbers when we reloaded (or first loaded!) the IP-to-country

forever in circuit_wait state. Now we close it after SocksTimeout
seconds. Bugfix on 0.1.2.7-alpha; reported by Mike Perry.

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.

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.
Bugfix on 0.1.2.1-alpha. Too obscure to backport.
svn:r18306
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.

crypto_global_init gets called. Also have it be crypto_global_init

RAND_poll in these fiddly cases.

It was dumb to have an "announce the value if it's over 0" version of
the code coexisting with an "announce the value if it's at least N"
version. Retain the latter only, with N set to 1.
Incidentally, this should fix a Coverity REVERSE_INULL warning.

Unfortunately, old Libevents don't _put_ a version in their headers, so
this can get a little tricky. Fortunately, the only binary-compatibility
issue we care about is the size of struct event. Even more fortunately,
Libevent 2.0 will let us keep binary compatiblity forever by letting us
decouple ourselves from the structs, if we like.

When we made bridge authorities stop serving bridge descriptors over
unencrypted links, we also broke DirPort reachability testing for
bridges. So bridges with a non-zero DirPort were printing spurious

descriptors shortly after startup, and then briefly resume
after a new bandwidth test and/or after publishing a new bridge
descriptor. Bridge users that try to bootstrap from them would
get a recent networkstatus but would get descriptors from up to
18 hours earlier, meaning most of the descriptors were obsolete
already. Reported by Tas; bugfix on 0.2.0.13-alpha.

discard it rather than trying to use it. In theory it could
be useful because it lists alternate directory mirrors, but in
practice it just means we spend many minutes trying directory
mirrors that are long gone from the network. Helps bug 887 a bit;
bugfix on 0.2.0.x.

The subversion $Id$ fields made every commit force a rebuild of
