Roger Dingledine	58366ffd24	when we changed from log_fn to debug/info/notice/warn/err, we screwed up the formatting in wild and unpredictable ways. fix it before it becomes convention to format logs in wild and unpredictable ways. still need to do src/common/ someday. svn:r5551	2005-12-10 09:36:26 +00:00
Nick Mathewson	b03e8733f3	Change how OR conns get removed from the identity map; fix some warnings on shutdown. svn:r5509	2005-12-05 19:15:27 +00:00
Nick Mathewson	a6eb8cd2a0	Move connection_or_remove_from_identity_map() to connection_unlink, but dont remove the other; just make it warn. svn:r5470	2005-11-30 04:28:41 +00:00
Nick Mathewson	3bd613b44d	Rename connection_get_by_identity_digest to reflect that it is OR-only. Make it use a hashtable instead of a linear search. svn:r5469	2005-11-30 03:01:16 +00:00
Nick Mathewson	652e1899ac	"How about 'never'? Does 'never' work for you?" Weasel says circuit_get_by_conn is his main timesink. Most of its users were just checking whether OR conns had circuits, so add a circuit count to OR conns, and check that. One was circuit_about_to_close_conn, which was doing an O(n^2) series of calls to get all circs on an OR conn, so make an O(n) function for that. Finally, circuit_get_by_edge_conn was using it as a sanity test that has been around for a while but never found any actualy insanity, so kill that. circuit_get_by_conn is finally dead, which is good, since it was never sane to begin with. svn:r5460	2005-11-26 01:43:57 +00:00
Nick Mathewson	31d5d96739	Cut down a common call to circuit_get_by_conn by about half. svn:r5459	2005-11-26 00:53:51 +00:00
Roger Dingledine	6452aecedb	when calling connection_get_by_identity_digest, don't do a memcmp for non-OR conns. this should save a bit of time. svn:r5456	2005-11-25 06:43:53 +00:00
Roger Dingledine	7aae63994f	Recover better from TCP connections to Tor servers that are broken but don't tell you (it happens!); and rotate TLS connections once a week. 1) If an OR conn becomes more than a week old, make it obsolete. 2) If it's obsolete and empty, kill it. 3) When an OR makes a second connection to you, allow it. 4) If we want to send a new create cell, but the best conn we've got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask for a new conn instead. 5) When we time out on circuit building on the first hop, make that connection obsolete. svn:r5429	2005-11-19 06:57:44 +00:00
Roger Dingledine	26d8c3498c	and another overly common log entry svn:r5417	2005-11-18 00:35:29 +00:00
Roger Dingledine	e6fd88c698	simplify a log entry svn:r5353	2005-11-11 17:03:35 +00:00
Nick Mathewson	80758473f8	fix a signed/unsigned warning svn:r5344	2005-11-01 17:28:49 +00:00
Roger Dingledine	bf2be9abd7	Do round-robin writes of at most 16 kB per write. This might be more fair on loaded Tor servers, and it might resolve our Windows crash bug. It might also slow things down. svn:r5332	2005-10-29 18:19:37 +00:00
Nick Mathewson	5d85560d9e	Remove last vestiges of old logging interface. svn:r5317	2005-10-25 18:01:01 +00:00
Nick Mathewson	452f4cfa09	Convert circuituse, command, config, connection, relay, router, test to new logging interface svn:r5308	2005-10-25 07:04:36 +00:00
Peter Palfrader	0d9aedfcea	Downgrade a few INFO level logs to DEBUG again. Also add two or three new logs in cases where a calling function's log was downgraded and we wouldn't get any log message otherwise. svn:r5263	2005-10-17 16:21:42 +00:00
Roger Dingledine	fd165329b8	start calling it ListenAddress rather than BindAddress, since none of our users know what it means to bind an address or port. svn:r5260	2005-10-17 03:17:29 +00:00
Peter Palfrader	7b15f77dd6	Make a few INFO log lines into DEBUG svn:r5257	2005-10-17 02:13:36 +00:00
Roger Dingledine	ae92a91d96	more log uncluttering svn:r5254	2005-10-17 01:29:28 +00:00
Roger Dingledine	78edd804ff	fix a malformed warning entry svn:r5219	2005-10-07 19:49:48 +00:00
Peter Palfrader	14934dece2	Print address too when we say we cannot bind/listen svn:r5213	2005-10-07 18:48:31 +00:00
Nick Mathewson	cc35e1720f	Using RAND_pseudo_bytes instead of RAND_bytes is an accident waiting to happen, and does not really speed us up much when we do it. So stop doing it. svn:r5210	2005-10-06 22:18:01 +00:00
Nick Mathewson	039edb3dbb	Downgrade too-frequent "nothing happened" message from info to debug svn:r5200	2005-10-05 22:32:59 +00:00
Nick Mathewson	6e4608701d	and another leak. svn:r5175	2005-09-30 21:31:26 +00:00
Roger Dingledine	ae30c8101b	by convention, addr is a uint32_t and address is a string. that's why we hadn't caught that leak. svn:r5174	2005-09-30 21:30:04 +00:00
Nick Mathewson	5c5d2e82e6	Fix a leak when launching listeners. svn:r5173	2005-09-30 21:28:00 +00:00
Nick Mathewson	92451f74a8	Reformat inconsistent function declarations. svn:r5160	2005-09-30 01:09:52 +00:00
Nick Mathewson	5c53545d81	Add a bunch more warnings to out warning suite; resolve them; pack structs a little better. svn:r5150	2005-09-29 22:59:17 +00:00
Nick Mathewson	7c6679d8dc	Add new config.c function to set options that can fail, and roll back if they do. This should solve the setconf-an-impossible-port bug. svn:r5046	2005-09-14 02:36:29 +00:00
Roger Dingledine	63bb27f19d	be more thorough about noticing when a directory request has failed: it has failed not only when the connection attempt fails, but also if the conn reaches eof before we get a response that we're happy with. svn:r5013	2005-09-12 07:36:26 +00:00
Nick Mathewson	3dc5e77b58	Numerous changes to move towards client-side v2 directories. connection.c: - Add some more connection accessor functions to make directory download redundancy checking work. directory.c, or.h, router.c, routerlist.c: - Start on logic to note when networkstatus downloads fail. dirserv.c, routerlist.c, routerparse.c: - Start maintaining an is_named field in routerstatus_t. Don't actually look at it yet. dirserv.c, routerlist.c: - Remove expired networkstatus objects. or.h: - Make some booleans into bitfields - Add prototypes routerlist.c: - Sort networkstatus list by publication time - Function to remove old (older than 10 days) networkstatus objects. - Function to set a list of routerinfo_ts' status info from the current set of networkstatus objects. - Function to tell which routerinfos we need to download based no the current set of networkstatus objects. - Do not launch a networkstatus download if a redundant one is in progress. routerparse.c: - Keep router entries in networkstatus sorted by digest. svn:r5012	2005-09-12 06:56:42 +00:00
Nick Mathewson	4ce0e01848	add conn->requested_resource to connection_t checks. svn:r4951	2005-09-08 21:21:54 +00:00
Nick Mathewson	059148f588	Only caches download network-status for now, and they use a different strategy. Add an element to connection_t to remember what we are downloading, and a function to recognize our own fingerprint. svn:r4944	2005-09-08 20:18:15 +00:00
Roger Dingledine	893acb3acc	Make a new AssumeReachable config option that will publish anyway. Also, let authdirservers start without setting their Address field. Something is still not working though. Will fix in morning. svn:r4839	2005-08-26 07:41:19 +00:00
Nick Mathewson	4e735da5da	Also set event_mask=0 in connection_free_all, and dont send events to marked control conns (for good measure) svn:r4729	2005-08-07 19:27:38 +00:00
Roger Dingledine	5c4da9dec6	incomplete patch for matt's info controller signal term bug svn:r4728	2005-08-07 19:20:55 +00:00
Nick Mathewson	303258972b	Fix idiot bug. The "free the IP history" code belons in connection_free_all(), not in connection_free(). You can all mock me now. svn:r4691	2005-08-04 18:29:01 +00:00
Nick Mathewson	11ff0aba80	Make clients regenerate their keys when their IP address changes. svn:r4688	2005-08-03 20:42:17 +00:00
Nick Mathewson	18c11eb3bc	Be consistent about preferring foo* to struct foo* svn:r4637	2005-07-22 21:12:10 +00:00
Nick Mathewson	c3a62c1739	Initial, somewhat dodgy implementation of helper nodes. It has too many XXXXs, it logs too verbosely, and it doesnt do persistence. svn:r4633	2005-07-22 17:32:25 +00:00
Roger Dingledine	452c98058f	missed one svn:r4567	2005-07-14 23:08:55 +00:00
Roger Dingledine	d8d0feb633	tell us what kind of listener it is, too svn:r4566	2005-07-14 23:07:05 +00:00

Roger Dingledine	2259032ea1	trivial changes on nick's rendezvous commit svn:r4553	2005-07-14 08:43:19 +00:00
Nick Mathewson	cf13b3e4a6	Macro-fu to get DEBUG events working. svn:r4539	2005-07-13 05:14:42 +00:00
Nick Mathewson	658e1196d0	Change retry_listeners: when force is false, close and re-open a minimal set of listeners (i.e., those that do not match the configuration). This fixes a possible bug on some windowses. Maybe. svn:r4528	2005-07-11 17:20:22 +00:00
Nick Mathewson	f9f09f1c5e	Start implementing framework for revised control spec. svn:r4447	2005-06-17 18:49:55 +00:00

Nick Mathewson	0831823763	Change end-of-file NLNL convention. It turns out arma I and I agree. svn:r4382	2005-06-09 19:03:31 +00:00
Roger Dingledine	cfc89f8753	pay more attention to the ClientOnly config option svn:r4367	2005-06-09 08:54:42 +00:00
Roger Dingledine	aff308e6d9	reenable the part of the code that tries to flush as soon as an OR outbuf has a full tls record available. perhaps this will make OR outbufs not grow as huge except in rare cases, thus saving lots of cpu time plus memory. svn:r4343	2005-06-08 04:55:06 +00:00
Roger Dingledine	040a748d87	i screwed up the dirport reachability testing when we don't yet have a cached version of the directory. hopefully now fixed. svn:r4284	2005-05-23 05:20:52 +00:00
Roger Dingledine	b86716b839	If a socks connection ends because read fails, don't warn that you're not sending a socks reply back. (bug reported by Warren Barrow) svn:r4277	2005-05-21 00:15:23 +00:00
Roger Dingledine	f0e309e5bd	add HttpProxyAuthenticator config option too svn:r4272	2005-05-20 08:51:45 +00:00

Roger Dingledine	5265bbd2b8	first iteration of scrubbing sensitive strings from logs. also generally clean up log messages. svn:r4174	2005-05-03 10:04:08 +00:00
Nick Mathewson	a312ce1d3b	Change buffer shrinking strategy: only try to shrink once every 3 minutes. Do not try to read over buffer size unless buffer is nearly empty. svn:r4165	2005-05-02 23:17:08 +00:00
Nick Mathewson	fe65e57ca1	Re-do fragmented control message handling to work with new buf_t system. svn:r4144	2005-04-27 22:01:34 +00:00

Nick Mathewson	31c12e265f	Move a quote, fix a log. svn:r4056	2005-04-08 03:26:44 +00:00
Roger Dingledine	dabafddb82	fix format bug svn:r4051	2005-04-07 22:03:56 +00:00
Nick Mathewson	8cc3307e0d	Improve conn_*_to_string; add circuit_state_to_string; make skewed-descriptor messages better. svn:r4047	2005-04-07 21:07:19 +00:00
Nick Mathewson	b897cb1ec3	Change conn_(type\|state)_to_string from const arrays to switch functions so we (I) will not make Tor crash the next time we (I) add a new state. svn:r4045	2005-04-07 20:25:22 +00:00
Roger Dingledine	620419b421	oh, and accept() into the right place, too. svn:r4029	2005-04-06 16:16:31 +00:00
Roger Dingledine	70f3b3ef86	Forward-port the checking of sin_addr.s_addr == 0 \|\| sin->sin_port == 0. This just happened on moria2, so I guess it happens rarely on Linux as well as OS X. We can't afford to accept OR conns from 0.0.0.0:0, since we send created cells back to the first addr:port that matches, and we'd better not send them to the wrong place. So, let's drop them all for now, and see if we can find a pattern later. svn:r4028	2005-04-06 15:42:35 +00:00
Roger Dingledine	9cbaf4603d	fix an assert trigger: when we have the rare case of accepting a conn on 0.0.0.0:0, then when we look through the connection array, we'll find any of the workers. this is no good. svn:r4027	2005-04-06 15:19:32 +00:00
Nick Mathewson	88dc243bb5	Rename circuit_get_by_stream to circuit_get_by_edge_conn, and actually start using it. Watch out, kids! svn:r4026	2005-04-06 06:43:21 +00:00
Roger Dingledine	5f0a84cbe2	update conn-type-state-strings to handle https states for ORs svn:r4018	2005-04-06 04:55:17 +00:00
Nick Mathewson	ac268a8340	Fix Tor for no-threading compilation: move connection_unregister from _connection_free to connection_free. svn:r4013	2005-04-06 00:46:57 +00:00
Nick Mathewson	0dc02328af	Move most of *_mark_for_close out of macros. svn:r3992	2005-04-03 05:22:33 +00:00
Nick Mathewson	0e81265359	update copyright notices. svn:r3982	2005-04-01 20:15:56 +00:00
Roger Dingledine	c2a05e1ca9	redo the state descriptors now that we have a controller-wait state svn:r3934	2005-03-31 17:36:24 +00:00
Roger Dingledine	36baf7219d	stop most cases of hanging up on a socks connection without sending the socks reject. audit for remaining ones. also make things more uniform so we always remember to hold-open-until-flushed, etc. svn:r3891	2005-03-27 04:55:13 +00:00
Roger Dingledine	1328383482	make it clearer to the human that his server is testing its reachability. tell him when it succeeds, or when 20 minutes pass and it hasn't succeeded yet. svn:r3882	2005-03-26 01:43:39 +00:00
Roger Dingledine	9b9dbad0b7	fix another case where we need to send a socks reply (reject) back before we close the conn. svn:r3876	2005-03-25 11:12:14 +00:00
Roger Dingledine	9685164fe5	don't mark a router down just because your httpsproxy is unreachable svn:r3874	2005-03-25 10:55:06 +00:00
Nick Mathewson	d26bcfab92	Note where connection that hasnt sent end was marked. svn:r3872	2005-03-25 05:54:50 +00:00
Roger Dingledine	bd37c9a3bd	REUSEADDR on normal places means you can rebind to the port right after somebody else has let it go. But REUSEADDR on win32 means to let you bind to the port _even when somebody else already has it bound_. So, don't do that on Win32. svn:r3867	2005-03-24 23:20:06 +00:00
Roger Dingledine	0dc91fd9c0	fix an assert -- we're not allowed to write onto a conn after we've connection_unregistered it. there's still more work to be done here, since we need to make sure to send back the socks-reply as soon as we know what it will be -- we can't just wait until connection-about-to-close to deal with it. svn:r3847	2005-03-23 23:19:18 +00:00
Roger Dingledine	fb8a319ffe	fix an over-eager assert, to make httpsproxy get a little farther svn:r3846	2005-03-23 22:11:59 +00:00
Roger Dingledine	a799dad937	forward-port the commenting out of the assert that glenn fink was triggering. we still don't know why he was triggering it. svn:r3841	2005-03-23 20:42:37 +00:00
Roger Dingledine	7373042a7b	fix assert triggers (bugs 109 and 96), and put in some debugging logs to notice future repeat bugs. svn:r3826	2005-03-23 02:52:55 +00:00
Roger Dingledine	e28b8aaa40	make httpsproxy more likely to work (don't let OR conns do tls until they've finished connecting and doing the proxy dance.) svn:r3824	2005-03-22 23:57:18 +00:00
Nick Mathewson	df9c8feac7	Commit fixes for several pending tor core tasks: document all DOCDOCed functions; time out uncontrolled unattached streams; feed reasons to SOCKS5 (refactoring connection_ap_handshake_socks_reply in the process); change DirFetchPeriod/StatusFetchPeriod to have a special "Be smart" value. svn:r3769	2005-03-17 12:38:37 +00:00
Nick Mathewson	97dad670ea	Renormalize whitespace svn:r3757	2005-03-14 03:18:35 +00:00

Nick Mathewson	afe414f070	Revise all calls to connection_edge_end to avoid sending MISC, and to take errno into account where possible. svn:r3720	2005-03-01 22:42:31 +00:00
Nick Mathewson	4ddf768a4f	Forward-port new reasons; clean up code more; add code to convert new reasons to SOCKS5 reply codes; add code to convert errnos to reasons. New code still needs to get invoked. svn:r3719	2005-03-01 22:16:15 +00:00
Nick Mathewson	b7b05dc1b2	make control interface stream IDs monotonically increasing to prevent possible races svn:r3715	2005-03-01 01:15:01 +00:00
Nick Mathewson	97bc49bd72	Try a little harder to avoid openssl SSL* double-free reports. svn:r3710	2005-02-28 02:52:51 +00:00
Nick Mathewson	26e6eb7539	Check returns from libevent calls better; stop poking at internals of events to see if they are live. svn:r3691	2005-02-25 05:42:01 +00:00
Nick Mathewson	24d7ae6fe8	Insert missing ! in assert_connection_ok; test was accidentally reversed in revision 1.329 yesterday. Should fix bug 102 svn:r3685	2005-02-24 17:08:27 +00:00
Nick Mathewson	22c38b0f9b	Clarify comment. Use CONN_IS_EDGE more. Try to be more zealous about calling connection_edge_end when things go bad with edge conns in connection.c svn:r3671	2005-02-23 20:35:26 +00:00
Nick Mathewson	6e6d95b3db	Change from inet_ntoa to a threadproof tor_inet_ntoa. svn:r3656	2005-02-22 08:18:36 +00:00
Nick Mathewson	c2d5b67dd2	After we successfully connect, try handling pending stuff immediately, rather than waiting for the next call to connection_handle_write. Roger: is this right? svn:r3647	2005-02-22 03:02:33 +00:00
Roger Dingledine	cbb4803ec8	forward-port some fixes svn:r3631	2005-02-17 01:12:50 +00:00
Roger Dingledine	37ca621301	when a client asks us for a dir mirror and we don't have one, launch an attempt to get a fresh one. svn:r3609	2005-02-10 06:31:34 +00:00
Roger Dingledine	07a3307460	remove redundant lines svn:r3607	2005-02-09 23:54:30 +00:00
Nick Mathewson	89d422914a	Patch from adam langley: always remove sockets from libevent before closing them. Should fix epoll-related bugs. svn:r3606	2005-02-09 23:16:31 +00:00
Roger Dingledine	efa9bb5535	fix the latest bug: don't explode when some router declares a bandwidthburst of 500 gigabytes. this bug seems to have taken down most of the network. oops. svn:r3523	2005-02-03 22:58:22 +00:00
Roger Dingledine	2e97593d25	define TOR_FRAGILE if you want tor to give you a core when something goes wrong. this should only be used by people actively tracking bugs. svn:r3487	2005-02-01 00:37:16 +00:00

Roger Dingledine	692a57c8e8	but don't spring the trip on worker children, because it turns out they don't actually remove anything before freeing the conns. svn:r3476	2005-01-31 01:02:20 +00:00
Roger Dingledine	d6489d8e41	lay a trap for situations where we connection_free something that's still on one of the lists. in particular, this will detect situations where we mark-for-close and then free it ourselves. svn:r3475	2005-01-31 00:33:32 +00:00
Roger Dingledine	38be533c69	Handle unavailable hidden services better. We try each intro point until none are left, then we try to refetch the descriptor. If it's the same one we had before, then close streams right then. Whenever a new stream arrives, even if it's right after, optimistically try refetching the descriptor, just in case. svn:r3379	2005-01-19 23:15:59 +00:00

Nick Mathewson	324b192f68	Make Tor use Niels Provos's libevent instead of it's current poll-but-sometimes-select mess. This will let us use faster async cores (like epoll, kpoll, and /dev/poll), and hopefully work better on Windows too. There are some fairly nasty changes to main.c here; this will almost certainly break something. But hey, that's what alphas are for. svn:r3341	2005-01-12 06:42:32 +00:00
Nick Mathewson	65c4fa2614	Split mark-dir-failed-and-retry logic into separate function; make it retry runningrouters as well as directory fetches; note that the do-we-need-to-give-up test is wrong. svn:r3256	2005-01-03 20:07:07 +00:00

Roger Dingledine	2532e9405e	Now we allow writing to the buffer even when the stream if marked for close, if we're planning to wait to flush it. This is important because we were sending a socks reject back if we're closing and hadn't already sent one, but it wasn't actually getting written since the conn was already marked-for-close. svn:r3074	2004-12-04 07:13:37 +00:00

Roger Dingledine	c1dc17e6e2	put in initial support for ".nickname.exit" addresses, to let alice decide what exit node to use; based on a patch by geoff goodell. needs more work: e.g. it goes bananas building new circuits when the chosen exit node's exit policy rejects the connection. svn:r3015	2004-11-29 08:34:54 +00:00

This means clients have a datadir again. - Introduce a global_write_bucket. We need to respond better to exhausting it. - Remove the last vestiges of LinkPadding and TrafficShaping. - Configuration infrastructure support for warning on obsolete options. - Refactor directory header parsing to use smartlist_split_string. - Respond to content-encoding headers by trying to uncompress as appropriate. - Reply with a deflated directory when a client asks for "dir.z".

Roger Dingledine	9bf9ca4d09	bugfix: add a circ->resolving_streams field, and make dns resolving streams not actually in the connection_array until they're done resolving. bugfix: actually complain if we duplicate mark-for-close a circuit add more logging for relay ends that claim dns resolve failed, so we can find out why they're not being retried. svn:r1798	2004-05-06 11:08:04 +00:00

Nick Mathewson	2ba2f02181	Integrate the new "rephist" [rep(utation) hist(ory)] module to trace successful/failed connections, successful/failed extends, and connection uptimes. It's still not done: more tests are needed, and not everything calls connection/circuit_mark_for_close properly. This skews the results. Also, there needs to be a 'testing' mode for non-OP ORs, where they periodically build circuits just to test whether extends work. svn:r1313	2004-03-20 04:59:29 +00:00
Roger Dingledine	74ef3a63ae	bugfix: decrement OR connections from global_bucket too bugfix: don't return immediately for has_pending_tls_data unless the conn is allowed to read svn:r1270	2004-03-14 17:06:29 +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

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

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	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
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	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

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

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	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
