- demand options->Bridges and options->TunnelDirConns if
options->UseBridges is set.
- after directory fetches, accept descriptors that aren't referenced by
our networkstatuses, *if* they're for a configured bridge.
- delay directory fetching until we have at least one bridge descriptor.
- learn how to build a one-hop circuit when we have neither routerinfo
nor routerstatus for our destination.
- teach directory connections how to pick a bridge as the destination
directory when doing non-anonymous fetches.
- tolerate directory commands for which the dir_port is 0.
- remember descriptors when the requested_resource was "authority",
rather than just ignoring them.
- put bridges on our entry_guards list once we have a descriptor for them.
When UseBridges is set, only pick entry guards that are bridges. Else
vice versa.

Adapt code to parse v3 networkstatus votes so it can also parse a consensus. Make networkstatus_vote_t the catch-all type for votes and conensuses. Correct/clarify the second argument to directory-signature.
svn:r10491
First bare stubs of ipv6 work: commit some (untested, hence doublessly broken) implementations of inet_ntop/pton for systems that lack them.
svn:r10326
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
Add math functions to round values to the nearest power of 2. Make mempools more careful about making sure that the size of their chunks is a little less than a power of 2, not a little more.
svn:r10304
First draft of code to generate votes. needs testing. does not yet upload or serve votes. Shares most of its code with the old generate_v2_networkstatus.
svn:r10295
More v3 directory code: have authorities load certificates; have everybody store certificates to disk and load them; provide a way to configure v3 authorities.
svn:r10293
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
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
More proposal-104 stuff: add most of the code for authorities to accept and serve extra-info documents. The back-end to store the things is missing.
svn:r9971
Initial code to parse extra-info documents as described in proposal 104. This is making me realize that the parsing code in routerparse.c is a little daft.
svn:r9963
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
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.
svn:r9944
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
Twiddle TODO around a bit: remove redundant items; mark completed and abandoned items; pull sub-items from redundant items into 0.2.0.x section; move items from aclocal.m4 into TODO; move some TODO items into 098-todo.txt; move one item onto flyspray.
svn:r9785
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
Niels has accepted the patch from Scott Lamb to implement better signal handling: I can take "get the pthread_sigprocmask situation under control" off my plate.
svn:r9696
Note another fun way that we could replace the more automatable parts of arma with software, thus leaving the less automatable bits free to do less automatable stuff.
svn:r9636
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 a longstanding dnsworker-related bug: when we decide to kill a DNS worker for having been in use too long, and we independently decide to close one of the exit connections waiting for that DNS worker (perhaps because we got an END relay cell), it was possible for us to try to double-free the connection. We were smart enough to detect this and assert, but not smart enough to fix this bug before now. This should resolve bug 390. Backport candidate.
svn:r9581
Implement proposal 106: stop requiring clients to have certificates, and stop checking for nicknames in certificates. [See proposal 106 for rationale.] Also improve messages when checking TLS handshake, to re-resolve bug 382.
svn:r9568
Write the entry guards section of path-spec; note a possible bug in cirbuitbuild.c; add a const; defer work on torrc.complete to be part of a bigger config documentation reorg.
svn:r9465
This one is a little tricky. Our BEGIN_DIR implementation has a
problem: the dirserv conns will decide they can flush all their data
immediately, since the edge_conns will read greedily.
For our 0.1.2 workaround, we track which or_conn a bridged dirserv
conn is attached to, and stop writing when its outbuf is too full, and
start writing again when the or_conn's outbuf empties out a little.
This requires a bit of pointer management. Let's hope it works.
svn:r9432
TODO items: Defer complicated solution to BEGIN_DIR memory problem; mark the simple one partially implemented; note a forward compatibility TODO.
svn:r9431
Implement SOCKS_BAD_HOSTNAME status event. Defer remaining status events. Clean up control-spec.txt a little, and fill in recommendations for events.
svn:r9374
Add some comments to TODO about nastiness of getting data-choking to work with directory bridges; propose a better solution for later, and some simpler solutions for now.
svn:r9321
Add (and specify) a BadDirectory flag to networkstatuses, so authorities can tell clients that some caches are broken. Also, implement an as-yet-unused function to estimate how many bytes will be sent on a directory connection.
