a335b43a67 If we have a routerstatus but no routerinfo to name a router, use the routerstatus instead when generating circuit events. Also refactor a little.

5d50bc3e1d We were already rejecting relay begin cells with destination port
of 0. Now also reject extend cells with destination port or address
of 0. Suggested by lark.

261670b57e Patch from lark: if we get two extend cells for the same circuit id, drop the second. Previously, we had leaked an extend_info if the target connection was not open when the second arrived.

c4b8fef362 Remove svn $Id$s from our source, and remove tor --version --version.
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed.  They were not actually useful for
telling the version of Tor files in the wild.

e5be0504ab When the client is choosing entry guards, now it selects at most
one guard from a given relay family. Otherwise we could end up with
all of our entry points into the network run by the same operator. 
Suggested by Camilo Viecco. Fix on 0.1.1.11-alpha.

Not a backport candidate, since I think this might break for users
who only have a given /16 in their reachableaddresses, or something
like that.

3e5a584d37 fix the other half of r17091. now that best_support can be -1,

caring about one-hop streams. patch from miner.

Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types.  Most of the Tor wire formats using these new types are in, but the code to generate and use it is not.  This is a big patch.  Let me know what it breaks for you.

Move n_addr, n_port, and n_conn_id_digest fields of circuit_t into a separately allocated extend_info_t.  Saves 22 bytes per connected circuit_t on 32-bit platforms, and makes me more comfortable with using tor_addr_t in place of uint32_t n_addr.

Add new ExcludeExitNodes option.  Also add a new routerset type to handle Exclude[Exit]Nodes.  It is optimized for O(1) membership tests, so as to make choosing a random router run in O(N_routers) time instead of in O(N_routers*N_Excluded_Routers).

267e61d0f3 When relays do their initial bandwidth measurement, don't limit
to just our our entry guards for the test circuits. Otherwise we
tend to have multiple test circuits going through a single entry
guard, which makes our bandwidth test less accurate. Fixes part
of bug 654; patch contributed by Josh Albrecht.

(Actually, modify Josh's patch to avoid doing that when you're
a bridge relay, since it would leak more than we want to leak.)

94dabd2c23 If you're using bridges, generate "bootstrap problem" warnings
as soon as you run out of working bridges, rather than waiting
for ten failures -- which will never happen if you have less than
ten bridges.

dd50ffb1de Big bridge bugfixes. Backport candidates.
If you have more than one bridge but don't know their keys,
you would only learn a request for the descriptor of the first one
on your list. (Tor considered launching requests for the others, but
found that it already had a connection on the way for $0000...0000
so it didn't open another.)
If you have more than one bridge but don't know their keys, and the
connection to one of the bridges failed, you would cancel all
pending bridge connections. (After all, they all have the same
digest.)
