Author	SHA1	Message	Date
Roger Dingledine	10cee8b7f7	fix a rare race condition: when we send a cell and then mark an OR connection expired, we might close it before finishing a flush if the other side isn't reading. svn:r1240	2004-03-06 06:05:00 +00:00
Roger Dingledine	516ef41ac1	if a stream times out after 15s without a connected cell, don't try that circuit again. svn:r1239	2004-03-06 05:10:07 +00:00
Roger Dingledine	c362ed877d	if the directory client hangs up before getting the directory, then give up on him svn:r1238	2004-03-06 05:09:33 +00:00
Roger Dingledine	6c9d78b319	stop asserting that computers always go forward in time it's simply not true svn:r1236	2004-03-06 01:43:37 +00:00
Nick Mathewson	1e5b7bc6f1	New, more flexible directory parsing backend. Uses a bit more RAM, but implements the new spec. Uses more RAM, but not so you would notice. svn:r1235	2004-03-05 05:48:28 +00:00
Roger Dingledine	01e06148a1	make workers explain their death better when tor dies and make them say it at log level info rather than err svn:r1232	2004-03-04 21:26:23 +00:00
Roger Dingledine	8fe504fee6	bugfix: don't pass complex things to the connection_mark_for_close macro svn:r1231	2004-03-04 20:49:38 +00:00
Nick Mathewson	c03e9206ae	Clean up dns->connection_mark_for_close->dns_remove path svn:r1230	2004-03-04 18:43:44 +00:00
Roger Dingledine	89d9d80e76	Store options->Address as IP, not hostname And figure it out while reading config, not every time you rebuild the descriptor svn:r1226	2004-03-04 01:53:56 +00:00
Nick Mathewson	b7633e2e67	Try to find out early if buffers get trashed or double-freed. svn:r1225	2004-03-03 22:49:15 +00:00
Roger Dingledine	5e2e6555a2	and a minor patch svn:r1215	2004-03-03 08:48:32 +00:00
Roger Dingledine	419a672222	holding until flush was borked we were never writing anything when hold_open_until_flushed was set, since conn_write returns early if marked_for_conn is set. seems a bit better now. svn:r1214	2004-03-03 08:46:18 +00:00
Roger Dingledine	6022bfea11	better debugging for lonely flushes svn:r1213	2004-03-03 07:26:58 +00:00
Roger Dingledine	d8e5f3a3a2	close immediately when write() fails too, else things will turn bad svn:r1212	2004-03-03 07:26:34 +00:00
Roger Dingledine	dbdd2eaa2a	don't mark_for_close again when the destroy arrives after the end cell svn:r1211	2004-03-03 07:24:53 +00:00

Roger Dingledine	8275e2302c	make socks5 not give a spurious warning also rename AP_CONN_STATE_CONNECTING to _CONNECT_WAIT svn:r1208	2004-03-03 04:54:16 +00:00
Roger Dingledine	77bb3e054e	reenable part of assert_circuit_ok, leave some still disabled svn:r1207	2004-03-03 04:11:18 +00:00

Nick Mathewson	a1e4c6dc85	Fix assertion failure spotted by arma. Apparently, when a DNS failure was already cached, then when we tried to mark the exit connection as closed, we'd try to remove it from the pending queue anyway, and hit an assert. Now, we put failed-resolve connections in a separate state so that mark_for_close does the right thing. svn:r1196	2004-03-02 07:24:11 +00:00
Roger Dingledine	b961732246	add --version, note that --help is probably obsolete svn:r1195	2004-03-02 05:19:01 +00:00

Nick Mathewson	5072488a95	make 'make test' exit(1) if a test fails. svn:r1190	2004-03-01 06:45:32 +00:00

Roger Dingledine	e2881631cf	fix duplicate call to connection_mark_for_close svn:r1187	2004-02-29 22:07:44 +00:00
Roger Dingledine	2ac37c64f2	bugfix: we were checking the wrong thing to see if 'reason' was out of range svn:r1186	2004-02-29 22:04:52 +00:00
Roger Dingledine	8e5c1921fc	when a stream is 15s late, print out the circuit at -l warn svn:r1180	2004-02-29 09:15:29 +00:00
Roger Dingledine	ef5f917e9e	print a statement when the first circ is finished, so the user knows it's working svn:r1179	2004-02-29 03:52:38 +00:00
Roger Dingledine	4716d4d871	bugfix: only warn about an unrouter router after we've fetched a directory svn:r1178	2004-02-29 01:31:33 +00:00
Roger Dingledine	b4338ce704	disable buffer tests, until we rewrite them (one of them fails) svn:r1177	2004-02-29 00:15:20 +00:00

Roger Dingledine	62d3df8633	bugfix: when we time out on a stream and detach, send an end first svn:r1175	2004-02-28 23:56:50 +00:00
Roger Dingledine	ae67c48805	bugfix: in some cases, connection_mark_for_close wasn't marking the conn svn:r1174	2004-02-28 23:52:56 +00:00
Roger Dingledine	3fb9c869a8	clearer warning message svn:r1173	2004-02-28 23:31:15 +00:00
Roger Dingledine	c058f87513	disallow changing from ORPort==0 to ORPort>0 on hup svn:r1172	2004-02-28 23:30:41 +00:00
Roger Dingledine	928db6dadc	cwd to datadir if it's defined, rather than / this way people can get cores if they want to svn:r1171	2004-02-28 23:23:06 +00:00
Roger Dingledine	5701cc2359	fix the function comment svn:r1169	2004-02-28 22:34:47 +00:00
Nick Mathewson	0a673f4491	Split dns_cancel_pending_resolve into dns_cancel_pending_resolve (kill a resolve in response to a DNS worker dying) and connection_dns_remove (remove a pending connection from the resolve structure.) svn:r1168	2004-02-28 22:23:44 +00:00
Roger Dingledine	9a55700747	add a log_warn to notify us of yet another potential dns.c bug svn:r1167	2004-02-28 22:13:58 +00:00
Nick Mathewson	833d14246d	Make dns_cancel_pending_resolve less agressive. svn:r1166	2004-02-28 22:06:59 +00:00
Nick Mathewson	55174d1cb0	Fix bug on dns_found_answer from mark_to_close stuff. svn:r1165	2004-02-28 21:52:58 +00:00
Roger Dingledine	fadfd26188	remove assert from dns.c that's no longer true: typically the resolve will be pending, but it could be failed if it just failed and we're working through the 'pending' list, or it could be valid if some other dnsworker raced us to fill in the entry. svn:r1164	2004-02-28 21:49:10 +00:00
Nick Mathewson	f039eca658	Stop trying to flush on broken sockets marked for close. svn:r1163	2004-02-28 19:14:11 +00:00
Roger Dingledine	80410fa8dc	some comments to point nick at the latest bugs svn:r1162	2004-02-28 11:48:22 +00:00
Roger Dingledine	cec2eee533	enable assert_connection_ok() we weren't actually asserting much. oops. svn:r1160	2004-02-28 07:51:30 +00:00
Roger Dingledine	70c43e152a	note bug in assert_connection_ok svn:r1159	2004-02-28 07:48:28 +00:00
Roger Dingledine	dd632e697e	clean up some log messages and severities still plenty more left to clean svn:r1158	2004-02-28 07:01:22 +00:00

Roger Dingledine	b354ecfecd	rename ExcludedNodes config option to ExcludeNodes svn:r1155	2004-02-28 05:09:37 +00:00
Roger Dingledine	3a1a6bb09e	if a relay cell is unrecognized at the end of the circuit, send back a destroy svn:r1153	2004-02-28 04:48:46 +00:00
Roger Dingledine	e59f19ca03	some more small fixes svn:r1152	2004-02-28 04:44:48 +00:00
Nick Mathewson	b4a7883c90	make code more readable; arrbitrarily change a -1 to a 0. svn:r1151	2004-02-28 04:34:27 +00:00
Nick Mathewson	ee68371f41	Stop answering "end" with "end" svn:r1150	2004-02-28 04:25:54 +00:00
Nick Mathewson	4e89c6661a	Push responsibility for connection marking down as far as possible; have only a close path; add some missing end cells; change return conventions a little. svn:r1149	2004-02-28 04:11:53 +00:00
Nick Mathewson	88e222ff76	Make has_sent_end irrelevant: only try to send end if reason is nonzero svn:r1148	2004-02-28 03:06:31 +00:00
Roger Dingledine	d0ad9b147a	and another one svn:r1147	2004-02-27 23:30:27 +00:00
Roger Dingledine	611f117ce1	patches/answers to nick's commit svn:r1146	2004-02-27 23:23:33 +00:00
Nick Mathewson	c5bbb571d2	Refactor mark_for_close, connection_edge_end and friends. Now, everybody who wants to shut down a connection calls connection_mark_for_close instead of setting marked_for_close to 1. This automatically removes the connection from the DNS cache if needed, sends a RELAY END cell if appropriate, and can be changed to do whatever else is needed. Still to do: - The same for circuits, maybe. - Add some kind of hold_connection_open_until_flushed flag, maybe. - Change stuff that closes connections with return -1 to use mark_for_close, maybe. svn:r1145	2004-02-27 22:00:26 +00:00
Roger Dingledine	737b2a0bf1	make 'connected' cells include the resolved IP svn:r1143	2004-02-27 04:52:02 +00:00
Roger Dingledine	195dfd35a8	Fix a bug where you might flush some data on a tls connection, and then add some more data to be flushed but never turn POLLOUT on. not sure how commonly this bug was hit, but it would be a doozy. Also add some asserts to see if it happens elsewhere. svn:r1142	2004-02-27 04:42:14 +00:00
Roger Dingledine	1b3c197fad	clean up an ia64 warning svn:r1140	2004-02-27 01:59:36 +00:00
Peter Palfrader	1bc2384c5a	Give the nice message about not being an HTTP proxy an <h1> headline svn:r1139	2004-02-27 01:33:02 +00:00
Roger Dingledine	d3e9afda27	When it can't resolve any dirservers, it was useless from then on. Now it reloads the RouterFile (or default dirservers) if it has no dirservers. svn:r1130	2004-02-26 22:56:36 +00:00
Roger Dingledine	4c48359ece	break out the operations done on sighup into their own function svn:r1129	2004-02-26 22:30:44 +00:00

Roger Dingledine	8f2b429a3b	when they use tor as an http proxy, give them an http 501 failure svn:r1126	2004-02-26 22:02:22 +00:00
Roger Dingledine	0b27ae0c2d	if the default torrc isn't there, just use some default defaults plus provide an internal dirservers file if they don't have one having no config files will make it easier to run on windows svn:r1124	2004-02-26 21:25:51 +00:00
Nick Mathewson	496e414e52	Basic RAM poisoning and magic-checking to notice connection and circuit corruption faster; also, check for corruption in dns.c so we can fail fast for the bug that's nailing Lucky and moria3. svn:r1123	2004-02-25 07:31:46 +00:00
Roger Dingledine	1b25794a56	bugfix: if the exit stream is pending on the resolve, and a destroy arrives, then the stream wasn't getting removed from the pending list. this may have been the lucky-bug. this commit may also not actually fix the bug. it's darn hard to reproduce. svn:r1122	2004-02-25 06:57:57 +00:00
Roger Dingledine	8da2e00a83	remove dead code svn:r1121	2004-02-25 06:56:11 +00:00

Nick Mathewson	67a273962a	On OSX, decline to use the built-in select-baed poll wrapper, since it seems to sometimes not work. svn:r1114	2004-02-20 23:41:45 +00:00
Roger Dingledine	67c0c64aa4	go back to a single exitpolicy parameter if your exitpolicy includes " :" then it is final, else we append the default exit policy. (thanks weasel) svn:r1105	2004-02-18 07:23:38 +00:00
Roger Dingledine	4e178907ab	allow imaps and pop3s in default exit policy svn:r1104	2004-02-18 04:02:05 +00:00
Roger Dingledine	7562a62ef0	Get rid of the notion of a separate default default exit policy. Create ExitPolicyPrepend config parameter, to customize the default exit policy. svn:r1103	2004-02-18 03:56:12 +00:00
Roger Dingledine	3456adec31	adding the reattach-after-timeout feature wasn't so easy after all. maybe it works now. svn:r1101	2004-02-18 01:21:20 +00:00
Roger Dingledine	39efb0ed52	retry streams where the connected cell hasn't arrived in 15 seconds svn:r1100	2004-02-17 21:07:15 +00:00
Nick Mathewson	72568d2620	Another case of the same. svn:r1099	2004-02-17 08:52:57 +00:00
Nick Mathewson	bab6c0a332	Fix the Big Bug in router_compare_addr_to_exit_policy: we used port 0 to mean "unknown port". But no exit policy supports (nonexistant) port 0, except accept :, and we had no special handling for 'unknown port'. Now we do. svn:r1098	2004-02-17 08:52:03 +00:00
Roger Dingledine	46ffc5984d	best_support_idx is obsolete (also doesn't fix the bug) svn:r1097	2004-02-17 08:42:25 +00:00
Nick Mathewson	bd14023afd	Propagate yes/no/maybe a little farther forward. svn:r1096	2004-02-17 08:29:22 +00:00
Roger Dingledine	d081d1d061	make braces cleaner, bug still persists svn:r1095	2004-02-17 08:10:07 +00:00
Nick Mathewson	61756b5893	Fix router_compare_addr_to_exit_policy, and name its return codes. The bug was: "maybe reject,accept" should be "maybe", not "accept". svn:r1093	2004-02-17 07:56:33 +00:00
Roger Dingledine	d508a194f7	Let paranoid exit nodes (which default to reject) be exit nodes Before we resolve the hostname, we don't know whether its IP will be accepted or rejected by the exit policy of each host. So we were only going with nodes that would certainly accept -- which was just itys and poblano. (This bug was hidden until now by the earlier port bug.) (Actual bugfix pending on Nick's next commit, hopefully.) svn:r1092	2004-02-17 07:45:44 +00:00

Roger Dingledine	c485725c5a	Fix the dns bug: children weren't dying We were telling a child to die by closing the parent's file descriptor to him. But newer children were inheriting the open file descriptor from the parent, and since they weren't closing them, the socket never closed, so the child never read eof, so he never knew to exit. As a side effect to this bug, we were probably failing to properly close connections to remote hosts, ORs, and OPs, after a dns child was born. I'm surprised Tor worked at all. svn:r974	2004-01-06 07:53:40 +00:00

Nick Mathewson	8a17d9e5d3	Finish implementing the rest of the exitpolicy stuff, except for automatically starting circuit builds. svn:r813	2003-11-16 05:33:45 +00:00
Nick Mathewson	a8eaa79e03	Improved exit policy syntax; basic client-side DNS caching. - Exit policies now support bitmasks (18.0.0.0/255.0.0.0) and bitcounts 18.0.0.0/8. Policies are parsed on startup, not when comparing to them. - desired_path_len is now part of an opaque cpath_build_state_t structure. - END_REASON_EXITPOLICY cells no longer include a port. - RELAY_COMMAND_CONNECTED cells now include the IP address we've connected to. - connection_edge now has a client_dns cache to remember resolved addresses. It gets populated by RELAY_COMMAND_CONNECTED cells and END_REASON_EXITPOLICY cells. It gets used by connection_ap_handshake_send_begin. We don't compare it to exit policies yet. svn:r812	2003-11-14 20:45:47 +00:00

Next, we move the responsibility for calling onion_extend_cpath into circuit.c (Later, we may want to special-case onion_extend_cpath to treat entry and exit routers differently.) svn:r792	2003-11-12 02:32:20 +00:00

Nick Mathewson	dafb0e6a6e	Make AP connections wait for a circuit if none exists. Also: - Refactor socks request into a separate struct - Add a separate 'waiting for circuit' state to AP connections between 'waiting for socks' and 'open'. Arma: can you check out the XXX's I've added to connection_edge? I may be mishandling some async and close logic. svn:r783	2003-11-11 02:41:31 +00:00

Nick Mathewson	7604cfe61b	Clock skew fixes. Allow some slop (currently 3 minutes) when checking certificate validity. Change certificate lifetime from 1 year to 2 days. Since we regenerate regularly (we regenerate regularly, right??), this shouldn't be a problem. Have directories reject descriptors published too far in the future (currently 30 minutes). If dirservs don't do this: 0) Today is January 1, 2000. 1) A very skewed server publishes descriptor X with a declared publication time of August 1, 2000. 2) The directory includes X. 3) Because of certificate lifetime issues, nobody can use the skewed server. 4) The server fixes its skew, and goes to republish a new descriptor Y with publication time of January 1, 2000. 5) But because the directory already has a "more recent" descriptor X, it rejects descriptor "Y" as superseded! This patch should make step 2 go away. svn:r658	2003-10-22 16:41:35 +00:00
Steven Hazel	4139c1c86a	- fixed a bug in the id switching code -- setgid has to happen before setuid, because after we setuid we don't have the priviledges we need to setgid anymore, duh. merged switch_user() and switch_group() into switch_id(), since that code has to be wound together. - return -1 from switch_id() if it's not defined to do anything else. - moved daemoinize(), write_pidfile(), and switch_id() from main.c to util.c svn:r656	2003-10-22 11:21:29 +00:00

Steven Hazel	b1eca56b77	added User and Group options -- if you set them, tor will try to setuid and setgid respectively, and die if it can't. (If the User option is set, tor will setgid to the user's gid as well.) This happens after the pidfile is created, so that in cases where tor needs to be root to work with the pidfile, it will at least be able to create it, although it won't be able to delete it. That sucks, but it's somewhat better than not being able to create the pidfile in the first place. svn:r652	2003-10-22 06:03:11 +00:00
Roger Dingledine	e4127e4d36	move closer to being able to reload config on HUP rename APPort to SocksPort introduce new tor_free() macro svn:r642	2003-10-21 09:48:17 +00:00
Roger Dingledine	4a66865d0b	send the end cell when we realize we're going to end, not when we're closing the stream. this lets us put a payload in the end cell if we want to, to describe why we're closing the stream. there are still some places where we don't send the end cell immediately. i need to track them down. but it's a low priority, since i've made it send the end cell when we close the stream if we haven't already sent it. svn:r640	2003-10-21 08:37:07 +00:00

Make conn->s = -1 by default (this might break things) When kill -USR1, prefer to log at INFO, but make sure they always see it. svn:r596	2003-10-15 18:50:16 +00:00

Roger Dingledine	9e5cafc395	first pass: obey log convention 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	2003-09-26 10:03:50 +00:00
Roger Dingledine	3b5191d36d	various bugfixes and updates redo all the config files for the new format (we'll redo them again soon) fix (another! yuck) segfault in log_fn when input is too large tor_tls_context_new() returns -1 for error, not NULL fix segfault in check_conn_marked() on conn's that die during tls handshake make ORs also initialize conn from router when we're the receiving node make non-dirserver ORs upload descriptor to every dirserver on startup add our local address to the descriptor add Content-Length field to POST command revert the Content-Length search in fetch_from_buf_http() to previous code fix segfault in memmove in fetch_from_buf_http() raise maximum allowed headers/body size in directory.c svn:r484	2003-09-25 10:42:07 +00:00
Nick Mathewson	3d4ccb781a	Refactor buffers; implement descriptors. 'buf_t' is now an opaque type defined in buffers.c . Router descriptors now include all keys; routers generate keys as needed on startup (in a newly defined "data directory"), and generate their own descriptors. Descriptors are now self-signed. Implementation is not complete: descriptors are never published; and upon receiving a descriptor, the directory doesn't do anything with it. At least "routers.or" and orkeygen are now obsolete, BTW. svn:r483	2003-09-25 05:17:11 +00:00
Roger Dingledine	40d0fca63a	cleanups, bugfixes, more verbose logs Fixed up the assert_*_ok funcs some (more work remains) Changed config so it reads either /etc/torrc or the -f arg, never both Finally tracked down a nasty bug with our use of tls: It turns out that if you ask SSL_read() for no more than n bytes, it will read the entire record from the network (and maybe part of the next record, I'm not sure), give you n bytes of it, and keep the remaining bytes internally. This is fine, except our poll-for-read looks at the network, and there are no bytes pending on the network, so we never know to ask SSL_read() for more bytes. Currently I've hacked it so if we ask for n bytes and it returns n bytes, then it reads again right then. This will interact poorly with our rate limiting; we need a cleaner solution. svn:r481	2003-09-24 21:24:52 +00:00

Nick Mathewson	22df330f14	Get directories working. Or at least, directories get generated, signed, download, and checked, with nobody seeming to crash. In config/*, added 'signing-key' blocks to dirservers and routers.or, so that everyone will know about the directories' signing keys. In or/directory.c, refrained from using a dirserver's signing key when no such key is known; added more debugging output. In or/main.c, added debugging output and fixed a few logic errors. In or/routers.c, added debugging output and prevented a segfault on routers_resolve_directory. The interleaving of arrays and lists on routerinfo_t is still messy, but at least it seems to work again. svn:r278	2003-05-08 21:35:11 +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	2147898577	Implemented router twins 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	2002-07-18 23:44:57 +00:00
Roger Dingledine	267434bdea	Implemented congestion control 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	2002-07-18 06:37:58 +00:00
Roger Dingledine	ccdef66b68	new link padding scheme we're now much more robust when bandwidth varies: instead of forcing a fixed bandwidth on the link, we instead use what the link will give us, up to our bandwidth. svn:r53	2002-07-16 18:24:12 +00:00
Roger Dingledine	c951c6f186	new config files, some bugfixes svn:r51	2002-07-16 02:12:58 +00:00
Roger Dingledine	117cbeeaaf	Implemented link padding and receiver token buckets Each socket reads at most 'bandwidth' bytes per second sustained, but can handle bursts of up to 10*bandwidth bytes. Cells are now sent out at evenly-spaced intervals, with padding sent out otherwise. Set Linkpadding=0 in the rc file to send cells as soon as they're available (and to never send padding cells). Added license/copyrights statements at the top of most files. router->min and router->max have been merged into a single 'bandwidth' value. We should make the routerinfo_t reflect this (want to do that, Mat?) As the bandwidth increases, and we want to stop sleeping more and more frequently to send a single cell, cpu usage goes up. At 128kB/s we're pretty much calling poll with a timeout of 1ms or even 0ms. The current code takes a timeout of 0-9ms and makes it 10ms. prepare_for_poll() handles everything that should have happened in the past, so as long as our buffers don't get too full in that 10ms, we're ok. Speaking of too full, if you run three servers at 100kB/s with -l debug, it spends too much time printing debugging messages to be able to keep up with the cells. The outbuf ultimately fills up and it kills that connection. If you run with -l err, it works fine up through 500kB/s and probably beyond. Down the road we'll want to teach it to recognize when an outbuf is getting full, and back off. svn:r50	2002-07-16 01:12:15 +00:00

Roger Dingledine	0a3da3ae37	put in the support for 'router twins' basically, a twin is a router which is different except it shares the same keypair. so in cases where we want to find a "next router" and all we really care is that it can decrypt the next onion layer, then a twin is just as good. we still need to decide how to mark twins in the routerinfo_t and in the routers config file. svn:r30	2002-07-08 08:59:15 +00:00

Roger Dingledine	d982925593	Integrated onion proxy into or/ The 'or' process can now be told (by the global_role variable) what roles this server should play -- connect to all ORs, listen for ORs, listen for OPs, listen for APs, or any combination. * everything in /src/op/ is now obsolete. * connection_ap.c now handles all interactions with application proxies * "port" is now or_port, op_port, ap_port. But routers are still always referenced (say, in conn_get_by_addr_port()) by addr / or_port. We should make routers.c actually read these new ports (currently I've kludged it so op_port = or_port+10, ap_port=or_port+20) * circuits currently know if they're at the beginning of the path because circ->cpath is set. They use this instead for crypts (both ways), if it's set. * I still obey the "send a 0 back to the AP when you're ready" protocol, but I think we should phase it out. I can simply not read from the AP socket until I'm ready. I need to do a lot of cleanup work here, but the code appears to work, so now's a good time for a checkin. svn:r22	2002-07-02 09:36:58 +00:00
Roger Dingledine	c603e403df	fixed a critical bug in yesterday's changes to buffers.c (starting to debug my OP integration) svn:r18	2002-07-02 06:02:15 +00:00

Roger Dingledine	bd627daa40	First cut at cleaning out a lot of the extra stuff. The summary here is that I'm requiring all developers to have auto* (aclocal, autoconf, automake) installed on their machine. Since different versions of auto* generate vastly different output, I'm going to leave its output out of the repository. This means that whenever you check out a repository, you need to run auto* to generate a configure file, then run ./configure to get a Makefile, then build. If you don't have auto* and can't get it, let me know (and I'll try to convince you to develop on moria). The benefit here is that while developers have a bit more work to keep things straight, we can build snapshots that will install just about anywhere (once we make configure.in work, that is ;) svn:r12	2002-06-29 00:54:00 +00:00
Felipe Bergo	3840dbcaaf	moved configure.ac to configure.in, should work with older autoconfs and automakes svn:r11	2002-06-28 23:43:00 +00:00
