* refactor; start adding debugging logs to midpoint rend stuffNick Mathewson2004-04-02
| | | | svn:r1445
* Add rendezvous-related metadata and code to circuits. Initially, weNick Mathewson2004-03-30
| | | | | | | | | | thought that a complicated adjunct structure would be necessary, but it doesn't look that way anymore. Of course, I might have forgotten something. svn:r1396
* Split out mark_for_close with circuits. Seems to work for me.Nick Mathewson2004-03-02
| | | | svn:r1197
* clean up some log messages and severitiesRoger Dingledine2004-02-28
| | | | | | | still plenty more left to clean svn:r1158
* checkpoint: revamp relay cell packaging and handlingRoger Dingledine2003-12-23
| | | | | | | | include the infrastructure for inserting padding cells when there's a relay-recognized conflict, but it does not work currently. svn:r958
* remove trailing whitespaceRoger Dingledine2003-12-17
| | | | svn:r951
* move cell size to 512 bytesRoger Dingledine2003-12-16
| | | | | | | | | move length to 2 bytes, put it in the relay header remove 4 reserved bytes in cell add 4 bytes to relay header for the integrity check svn:r942
* add H(K|1) to the onionskin replyRoger Dingledine2003-12-16
| | | | | | | | | | verify it at the client end abstract the onionskin handshake lengths breaks backward compatibility (again) svn:r941

| | | | svn:r533
* bugfixes and features: closer to making dirserv workRoger Dingledine2003-09-29
| | | | | | | | | | | fix a variety of seg faults don't try to list OPs in running-routers write cached-directory to disk when rebuilding the dir on boot, dirservers load approved-routers file on boot, dirservers load cached directory file svn:r508
* clean up receiver buckets; prepare for payloads in relay_end; note a few bugsRoger Dingledine2003-09-27
| | | | svn:r502
* first pass: obey log conventionRoger Dingledine2003-09-26
| | | | | | | | | | | | | | | | | | | | | ERR is if something fatal just happened WARNING is something bad happened, but we're still running. The bad thing is either a bug in the code, an attack or buggy protocol/implementation of the remote peer, etc. The operator should examine the bad thing and try to correct it. (No error or warning messages should be expected. I expect most people to run on -l warning eventually.) NOTICE is never ever used. INFO means something happened (maybe bad, maybe ok), but there's nothing you need to (or can) do about it. DEBUG is for everything louder than INFO. svn:r486
* clean up exported api'sRoger Dingledine2003-09-16
| | | | svn:r461
* implemented cpuworkersRoger Dingledine2003-08-20
| | | | | | | | | | please poke at it and report bugs still needs polishing, and only handles onions now (should handle OR handshakes too) svn:r402
* Change many files to new log_fn formatNick Mathewson2003-06-17
| | | | svn:r333
* relay queues are obsolete (woo!)Roger Dingledine2003-06-13
| | | | | | | | | | | they used to be used for * queueing relay cells at the edge of the network, when windows are empty * queueing relay cells that arrive after an onion but before the onion has been processed. both of these uses are gone. so out they go. svn:r315
* send truncates AP-ward in a circuit, not destroysRoger Dingledine2003-06-13
| | | | svn:r313
* implement truncate and truncated (untested)Roger Dingledine2003-06-12
| | | | | | | clean up circuit_deliver_relay_cell convention svn:r312
* remove dead codeRoger Dingledine2003-05-20
| | | | | | | | | | circuits no longer queue more cells when the windows are empty -- they simply don't package it from the buffer if they're not going to want it. we can restore this code later if we need to resume queueing. svn:r294
* add circuit-level sendme relay cellsRoger Dingledine2003-05-20
| | | | | | | | | | remove sendme cells replace malloc with tor_malloc patch (but not track down) bug in onion pending list streamline connection_ap handshake svn:r293
* sign directories with the signing keyRoger Dingledine2003-05-07
| | | | svn:r274
* put some symbolic constants to the onion skin lengthsRoger Dingledine2003-05-06
| | | | svn:r265
* incremental path building in; uses ephemeral DH; onions are goneRoger Dingledine2003-05-05
| | | | | | | still need to change circuit-level sendmes svn:r264
* streams are now 8 bytes, and are recognized by intermediate hopsRoger Dingledine2003-05-02
| | | | | | | | the OP only crypts the appropriate number of times depending on which layer (hop on the path) it's for/from. svn:r262
* terminology shift: data->relay, topic->relay, topic->streamRoger Dingledine2003-05-01
| | | | svn:r258
* bugfix: a circ can't be youngest if it's still connecting to the first hopRoger Dingledine2003-04-20
| | | | svn:r255
* bugfix: refactor to always use circuit_removeRoger Dingledine2003-04-20
| | | | | | | this way we can always check if a new circ needs to be launched svn:r254
* further cleanup, test.c still has some bugsRoger Dingledine2003-04-16
| | | | svn:r241
* Factor out timeval-related functions.Nick Mathewson2003-04-16
| | | | svn:r237
* Add magic to end of C files to make emacs happy; split test invocation into ↵Nick Mathewson2003-04-07
| | | | | | separate file. svn:r224
* be less noisy at -l info, now that flow control bug is solvedRoger Dingledine2003-03-10
| | | | svn:r172
* Bugfixes and enhancements in sendmes and dns farmRoger Dingledine2003-02-18
| | | | svn:r161
* major overhaul: dns slave subsystem, topicsRoger Dingledine2003-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | on startup, it forks off a master dns handler, which forks off dns slaves (like the apache model). slaves as spawned as load increases, and then reused. excess slaves are not ever killed, currently. implemented topics. each topic has a receive window in each direction at each edge of the circuit, and sends sendme's at the data level, as per before. each circuit also has receive windows in each direction at each hop; an edge sends a circuit-level sendme as soon as enough data cells have arrived (regardless of whether the data cells were flushed to the exit conns). removed the 'connected' cell type, since it's now a topic command within data cells. at the edge of the circuit, there can be multiple connections associated with a single circuit. you find them via the linked list conn->next_topic. currently each new ap connection starts its own circuit, so we ought to see comparable performance to what we had before. but that's only because i haven't written the code to reattach to old circuits. please try to break it as-is, and then i'll make it reuse the same circuit and we'll try to break that. svn:r152
* bugfix: couldn't send two creates, two datas, and the destroy all at onceRoger Dingledine2002-12-23
| | | | | | | | (amazing the odd behavior you get to test when you have a flaky modem connection) svn:r148
* create cells are now queued and processed only when idleRoger Dingledine2002-11-27
| | | | | | | | | | | we also queue data cells destined for a circuit that is pending, and process them once the circuit opens destroys reach into the queue and remove the pending onion, along with its collected data cells svn:r142
* per-second cell statistics to help with profilingRoger Dingledine2002-11-24
| | | | svn:r140
* added OnionsPerSecond to prevent create floodingRoger Dingledine2002-11-23
| | | | | | | first cut, probably needs more playing with svn:r137
* cell.c is now obsoleteRoger Dingledine2002-10-03
| | | | svn:r133
* added 'connected' cell typeRoger Dingledine2002-09-17
| | | | | | | see http://archives.seul.org/or/dev/Sep-2002/msg00018.html svn:r103
* port is now kept in host order except in sin_portRoger Dingledine2002-08-24
| | | | svn:r82
* Folded cell.? into src/orRoger Dingledine2002-07-19
| | | | svn:r64
* Implemented router twinsRoger Dingledine2002-07-18
| | | | | | | | | | | I modified new_route so we don't pick twins back-to-back in the path. I also had to patch my previous uses of connection_twin_get_by_addr_port() because they assumed that "addr" and "port" would be the same for a twin as for the original router. svn:r56
* Implemented congestion controlRoger Dingledine2002-07-18
| | | | | | | | | | | | | | | Servers are allowed to send 100 cells initially, and can't send more until they receive a 'sendme' cell from that direction, indicating that they can send 10 more cells. As it currently stands, the exit node quickly runs out of window, and sends bursts of 10 whenever a sendme cell gets to him. This is much much much faster (and more flexible) than the old "give each circuit 1 kB/s and hope nothing overflows" approach. Also divided out the connection_watch_events into stop_reading, start_writing, etc. That way we can control them separately. svn:r54
