Well, that was easier than I thought it would be. Tor is now a DNS proxy as well as a socks proxy. Probably some bugs remain, but since it A) has managed to resolve one address for me successfully, and B) will not affect anybody who leaves DNSPort unset, it feel like a good time to commit.
svn:r10317
backport candidate: Warn when using a version of libevent before 1.3b to run a server on osx or bsd: these versions of libevent interact badly with userspace threads.
svn:r10307
Partial backport candidate: We had a bug where we were downloading descriptors by descriptor digest, but trying to look them up by identity fingerprint when updating their failure count and next retry time. (Also use correct backoff logic for extrainfo code.) Needs testing, doubtless.
svn:r10210
Patch from shibz: implement a getinfo status/version/... so a controller can tell whether the current version is recommended, whether any versions are good, and how many authorities agree.
svn:r10162
If a directory server runs out of space in the connection table
as it's processing a begin_dir request, it will free the exit stream
but leave it attached to the circuit, leading to unpredictable
behavior. (Reported by seeess, fixes bug 425.)
svn:r10154
[Backport candidate] On windows, open cached-routers with the sharing mode "FILE_SHARE_READ so that other processes can read it while Tor is running. (Reported by Janbar).
svn:r10148
authorities should set. This will let future authorities choose
not to serve V2 directory information.
Also, go through and revamp all the authdir_mode stuff so it tries
to do the right thing if you're an auth but not a V1 or V2 auth.
svn:r10092
(Needs review.) Allow directory authorities to accept multiple router descriptors and extra info documents in a single POST. This will make implementing the client side of proposal 104 a lot simpler.
svn:r10069
Initial version of patch from Karsten Loesing: Add an HSAuthorityRecordStats option to track statistics of overall hidden service usage without logging information that would be useful to an attacker.
svn:r10067
Backport candidate: Add asserts to dirserv_remove_invalid, and fix a bug in dirserv_remove_invalid that could mess with pointers in a freed routerinfo right after it was freed.
svn:r10052
Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention.
svn:r9995
Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.
svn:r9994
Refactor router/directory parsing backend: use a separate token table for everything that we parse, and enforce the correct count of each item.
svn:r9965
More autoconf hacking: use same machinery to find zlib as for openssl and libevent. Have unified library finder include setup for --with variable. Start trying to suggest to the user what packages they should install if finding the library fails.
svn:r9945
A surprisingly simple patch to stop reading on edge connections when their circuits get too full, and start again when they empty out. This lets us remove the logic to block begin_dir conns when the corresponding or conns get full: it was already broken by cell queues anyway.
svn:r9905
Initial version of circuit-based cell queues. Instead of hammering or_conns with piles of cells, queue cells on their corresponding circuits, and append them to the or_conn as needed. This seems to work so far, but needs a bit more work. This will break the memory-use-limitation patch for begin_dir conns: the solution will be a fun but fiddly.
svn:r9904
directory information requested inside Tor connections (i.e. via
begin_dir cells). It only triggered when the same connection was
serving other data at the same time. Reported by seeess.
Backport candidate.
svn:r9841
behavior for getinfo addr-mappings/*. this is because
the code and spec have been mismatched since at least
0.1.1.x, so i would be surprised if nobody at all is
relying on the current behavior.
backport candidate.
backbackport candidate.
svn:r9823
uptime of at least 30 days, even if that's not the median uptime
in the network. Implements proposal 1xx, suggested by Kevin Bauer
and Damon McCoy.
svn:r9788
Remove support for v0 control protocol from 0.2.0.x trunk; send back error when we receive a v0 control message. (Leave "if(v1){...}"blocks indented for now so this patch is easier to read.) ((Finally, the linecount goes _down_ a little.))
svn:r9735
Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)
svn:r9733
nt_service_is_stopping should not load the NT service library calls: if they are not loaded, we cannot possibly be a service trying to shut own. Bug found by "norvid" on or-talk. Also, rename function to something slightly less error-prone.
svn:r9720
On mingw, use "%I64u" to printf/scanf 64-bit integers, instead of the usual GCC "%llu". This prevents a bug when saving 64-bit int configuration values on mingw; the high-order 32 bits would get truncated. If the value was then reloaded, disaster would occur. (Fixes bug 400 and maybe also bug 397.) Backport candidate.
svn:r9691
Fix a bug found by Udo van den Heuvel: avoid an assertion failure when a controller sets and clears EntryNodes before the next call to choose_random_entry(). Also make a function static.
svn:r9669
try to make aes encryption of cells about 30-40% faster where applicable. offer not available for all architectures or all versions of openssl.
svn:r9663
Fix connection_get_by_type_state_rendquery(): This has been bogus for most of 0.1.2.x. Thanks to Karsten Loesing for finding the bug; fixes bug 399.
svn:r9651
Make remap stream events have a souce; make them generated every time we get a successful connected or resolved cell. Also change reported stream target address to IP consistently when we get the IP from an exit node.
svn:r9624
Fix two XXXX012 issues in routerlist.c: a possible performance issue hasnt shown up on any profiles, so unflag it. Stop warning when we get a router descriptor that we asked for but no longer want: just drop it (if we are not a cache) or cache if (if we are).
svn:r9616
Another optimization suggested by Shark output: shave off >90% of uses of logv by cutting down on calls to log_debug when log actually debugging. This is showing up in some profiles bug not others, and might be as much as 2.5%.
svn:r9612
As a trivial optimization, remove a redundant call to router_have_minimum_dir_info. This might shave 2% on some systems by according to some profilers.
