Roger Dingledine	0bc8dc1314	fix endian issues for topics -- they might work on bsd now ... (they wouldn't have before) alternate code which bypasses the dns farm, so we can compare speed svn:r154	2003-02-06 23:48:35 +00:00
Roger Dingledine	ceafe12ed6	make reusing circuits work (and be the default) ... performance is better, but not by much. not sure why yet. svn:r153	2003-02-06 08:00:49 +00:00
Roger Dingledine	c35373a2cf	major overhaul: dns slave subsystem, topics ... 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	2003-01-26 09:02:24 +00:00
Roger Dingledine	bf52b6d1f4	splay and rbtree implementations, by niels provos ... taken from openbsd svn:r151	2002-12-31 15:05:07 +00:00
Roger Dingledine	9d3e80a589	use a rbtree for replay detection, rather than linear search ... when we had lots of new onions coming in, we were using 40% of our time searching through the tracked_onions linked list. svn:r150	2002-12-31 15:04:14 +00:00
Roger Dingledine	0b717a3e74	give us more aci-space ... svn:r149	2002-12-30 08:51:41 +00:00
Roger Dingledine	fbf4ca3ff8	bugfix: couldn't send two creates, two datas, and the destroy all at once ... (amazing the odd behavior you get to test when you have a flaky modem connection) svn:r148	2002-12-23 06:48:14 +00:00
Roger Dingledine	cbd2cdf04f	onions go on and off the network correctly now ... we're closer to an OS X port CVS: ---------------------------------------------------------------------- svn:r146	2002-12-03 22:18:23 +00:00
Roger Dingledine	bd97deb919	onions expire after a day, not an hour ... this was a major faq, because it would fail with an error only on the *server* side when the client-side time was wrong. the client would simply not work. svn:r145	2002-12-03 07:06:13 +00:00
Roger Dingledine	8f2beefca4	was leaking 28 bytes every 100 minutes ... svn:r144	2002-12-03 05:12:30 +00:00
Roger Dingledine	ac10bb6319	two more rare race conditions ... svn:r143	2002-11-28 07:32:30 +00:00
Roger Dingledine	8f18647a33	create cells are now queued and processed only when idle ... 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	2002-11-27 04:08:20 +00:00
Roger Dingledine	147879ab17	removing more unused files ... svn:r141	2002-11-25 01:22:34 +00:00

Roger Dingledine	00a9e3732e	remove popt dependency, consolidate config stuff ... reformat parts of onion.c svn:r136	2002-11-23 06:49:01 +00:00
Roger Dingledine	121d029584	fix subtle race condition ... If you weren't connected to a given router, and you made a directory request to it simultaneously with a new web query that caused you to want to connect to that OR... it would think you're already connected. svn:r135	2002-10-14 06:44:48 +00:00
Roger Dingledine	84a34edfa1	expire unfinished handshakes too ... don't list non-open ORs in the directory svn:r134	2002-10-13 13:17:27 +00:00

Nick Mathewson	bef3424bec	Add convenience functions to wrap create and init for symmetric ciphers; clean up error handling in onion.c ... svn:r131	2002-10-02 20:39:51 +00:00
Roger Dingledine	7032d16e78	cell now has a network appearance and an internal (struct) appearance ... svn:r130	2002-10-02 20:12:44 +00:00
Roger Dingledine	e3fd91755d	preemptive bugfix ... svn:r129	2002-10-02 04:07:33 +00:00
Roger Dingledine	b3b763ad11	all listeners listen on 0.0.0.0 except AP which listens on 127.0.0.1 ... svn:r126	2002-10-02 01:03:00 +00:00
Roger Dingledine	7ed6c8bd39	introduced a periodic keepalive padding cell ... now tor can be run safely inside nat'ed areas that kill idle connections; and the proxy can handle when you suspend your laptop and then emerge hours later from a new domain. svn:r125	2002-10-01 23:37:31 +00:00
Roger Dingledine	293e049a89	handle banners from the server side ... (text that it spits out immediately upon connect) svn:r124	2002-10-01 05:46:48 +00:00

Roger Dingledine	22285e6ff1	cleanup ... prkey is only fetched when it's needed tor nodes who aren't dirservers now fetch directories and autoconnect to new nodes listed in the directory default role is a non-dirserver node svn:r120	2002-09-28 00:52:59 +00:00
Roger Dingledine	6934eb9f10	mozilla actually cares about the reply version ... tor can now interface directly with mozilla, as a socks 4 host. but note that mozilla does the dns resolution itself, so you're leaking anonymity. svn:r119	2002-09-27 23:34:51 +00:00
Roger Dingledine	23264ebcb5	support socks4 too ... svn:r118	2002-09-27 23:16:39 +00:00

Roger Dingledine	f033442be2	dirserver should include itself in the directory ... if connecting to a dirserver fails, remove it from the router array svn:r113	2002-09-26 13:17:14 +00:00
Roger Dingledine	01f6727306	directory servers in and functional ... proxies now periodically pull down an hourly-updated directory, and replace their router list with it if it parses correctly. svn:r112	2002-09-26 12:09:10 +00:00
Roger Dingledine	d6360c57bc	another bugfix on the proxy side ... should be more reliable now (?) svn:r111	2002-09-26 05:50:51 +00:00
Roger Dingledine	253f0f160e	laying the groundwork for dynamic router lists ... revamped the router reading section reference counting for crypto pk env's (so we can dup them) we now read and write pem pk keys from string rather than from FILE*, in anticipation of fetching directories over a socket (so now on startup we slurp in the whole file, then parse it as a string) fixed a bug in the proxy side, where you could get some circuits wedged if they showed up while the connection was being made svn:r110	2002-09-24 10:43:57 +00:00
Roger Dingledine	988c6d4277	more robust when only some of the socks info has arrived ... svn:r108	2002-09-23 01:04:59 +00:00
Roger Dingledine	155c9b80ca	onion proxy now speaks socks4a ... httpap is obsolete; we support privoxy directly now! smtpap is obsolete; need to find a good socks4a-enabled smtp proxy/client I dub thee 0.0.1. svn:r107	2002-09-22 11:09:07 +00:00
Roger Dingledine	8d1aa27c46	kill -USR1 the or and it will dump conn/circuit stats to stdout ... svn:r106	2002-09-21 22:41:48 +00:00

Roger Dingledine	958ec8d4fb	port to actual BSD ... (hey nick, does this break the os x build?) you still need to add some stuff to the ./configure commandline... anybody know a better solution? svn:r101	2002-09-09 04:10:58 +00:00
Roger Dingledine	1e4e0244dd	minor race condition ... (it seemed to work anyway, but...) svn:r100	2002-09-09 04:06:59 +00:00
Roger Dingledine	f9f3e2f120	slight optimization on rsa exponent ... use 2**16+1 rather than 2**16 + 2**(-1) svn:r99	2002-09-05 19:04:47 +00:00

Roger Dingledine	4eb0158f42	the logs now include a timestamp and severity ... the implementation is sort of a kludge..you're welcome to fix it up svn:r94	2002-09-04 00:39:33 +00:00
Roger Dingledine	adfd11b9ac	changed my mind, sort of ... the package is tor, the binary is or. and i added our project plan to the todo file. svn:r93	2002-09-03 22:53:34 +00:00
