Nick Mathewson	65974f82fa	r8839@Kushana: nickm \| 2006-09-17 16:11:59 -0400 Add some client performance XXXXs; try to move some common case tests higher on their decision trees. svn:r8410	2006-09-17 20:12:10 +00:00
Roger Dingledine	c22dc94fe6	make my bandwidth exercises actually happen svn:r8400	2006-09-15 05:53:00 +00:00
Peter Palfrader	9d9e31dcf4	r9752@danube: weasel \| 2006-09-14 07:06:49 +0200 Fix some dead code that is on occasion useful svn:r8389	2006-09-14 05:07:26 +00:00
Peter Palfrader	984e8f6efb	r9736@danube: weasel \| 2006-09-14 05:53:06 +0200 Refactor dirserv_parse_fingerprint_file(fname) into dirserv_load_fingerprint_file(): There is not need to put together the path to the approved-routers file in more than one place. svn:r8386	2006-09-14 04:53:23 +00:00
Mike Chiussi	6ec9c1092a	- made configure check if we are building for win32 - made configure link to required system dll's if building for win32 - added diffs for libevent 1.1b - forced user to turn off eventdns if win32 is set - cleaned up tor_mmap_file()_win32 (not sure if it's stable) - cleaned up some warnings and typos svn:r8322	2006-09-06 01:49:55 +00:00
Roger Dingledine	2499d1db7c	and make the comment better, while i'm at it svn:r8273	2006-08-28 19:02:57 +00:00
Roger Dingledine	2a4d5782ef	an even better check -- now servers hang up if they can't write for a while, and clients hang up if they can't read for a while. svn:r8272	2006-08-28 19:00:17 +00:00
Roger Dingledine	f75ef94f27	fix bug found by Adam J. Richter: directory clients shouldn't hang up five minutes after they begin. but directory servers should still hang up after 5 minutes of failing to deliver any bytes. svn:r8271	2006-08-28 18:51:36 +00:00
Nick Mathewson	54ca0387a5	r8608@Kushana: nickm \| 2006-08-27 16:57:47 -0400 Make it possible to change nameserver options while Tor is running. svn:r8255	2006-08-28 03:15:55 +00:00
Roger Dingledine	24ad1e06cf	i'm guessing nick meant to check the return value of dns_init. and revise some log severities to match the convention. svn:r8234	2006-08-27 01:41:08 +00:00
Roger Dingledine	9ebaf01096	clean up logging conventions in do_list_fingerprint() svn:r8222	2006-08-24 00:54:18 +00:00
Roger Dingledine	41d8d77c8b	tor --verify-config now exits with -1(255) or 0 depending on whether the config options are bad or good. svn:r8221	2006-08-23 23:45:03 +00:00
Nick Mathewson	0f5bfc1521	r7411@Kushana: nickm \| 2006-08-17 19:00:25 -0400 patch suggested by Karsten Loesing: respond to SIGNAL command before we execute the signal, in case the signal shuts us down. svn:r7072	2006-08-17 23:00:32 +00:00
Roger Dingledine	5647e5c7e6	fix typo, add explanatory comment svn:r7026	2006-08-11 07:31:16 +00:00
Nick Mathewson	09a895e222	r7324@Kushana: nickm \| 2006-08-10 23:23:15 -0700 Add more warnings to the list of those we tolerate. Start using GCC attributes more, for better error checking and better code generation. svn:r7020	2006-08-11 07:09:17 +00:00
Nick Mathewson	85f381153b	r6949@Kushana: nickm \| 2006-07-28 10:17:38 -0400 Shave another 8 bytes from connection_t: turn inbuf_reached_eof into a bit, and lower timestamp_lastempty to or_connection_t svn:r6934	2006-07-28 15:11:20 +00:00
Nick Mathewson	5227395aba	r6922@Kushana: nickm \| 2006-07-26 16:32:24 -0400 Rename some fields, compress a bitfield, and document some structs and fields svn:r6919	2006-07-27 05:03:57 +00:00
Nick Mathewson	ec82db6995	r6909@Kushana: nickm \| 2006-07-26 13:05:58 -0400 Clean up wide lines from last patch. svn:r6907	2006-07-26 19:07:37 +00:00
Nick Mathewson	4ff4577beb	r6908@Kushana: nickm \| 2006-07-26 12:38:52 -0400 Refactor connection_t into edge, or, dir, control, and base subtypes. This might save some RAM on busy exit servers, but really matters most in terms of correctness. svn:r6906	2006-07-26 19:07:26 +00:00
Roger Dingledine	c9b8458f59	publish a new descriptor after we hup. this is important if our config has changed such that we'll want to start advertising our dirport now, etc. svn:r6819	2006-07-23 11:50:03 +00:00
Roger Dingledine	00aefaab6b	think harder about my logic svn:r6806	2006-07-22 07:19:11 +00:00
Roger Dingledine	2d6a4d283b	i lied, that won't work at all. maybe this will. svn:r6805	2006-07-22 07:15:34 +00:00
Roger Dingledine	444f096d2d	more bulletproof reachability testing svn:r6804	2006-07-22 05:29:31 +00:00
Roger Dingledine	2249180b60	bugfix: if you find yourself reachable, then don't ever make any client requests (so you stop predicting circuits), then hup, then later your IP changes, you won't think circuits are working so you won't try to test reachability, so you won't publish. svn:r6800	2006-07-21 07:55:35 +00:00
Nick Mathewson	7fcb267e24	Oh. And apparently, msvc6 doesnt think very much of doing u64-and-double arithmetic either. svn:r6785	2006-07-18 02:24:01 +00:00
Roger Dingledine	42e2057d67	fix some more places where we shouldn't crash if we can't build our own descriptor yet. svn:r6775	2006-07-17 06:54:28 +00:00
Nick Mathewson	e572d5990c	MSVC6 is apparently terrified of unnatural cross-breeding between uint64_t and double, and needs more persuasion than usual to cast one to the other. Issue identified by Frediano Ziglio; patch revised for minimal impact on non-MSVC6 compilers. svn:r6768	2006-07-17 00:39:05 +00:00
Roger Dingledine	05d0b70573	Get rid of the router_retry_connections notion. Now routers no longer try to rebuild long-term connections to directory authorities, and directory authorities no longer try to rebuild long-term connections to all servers. We still don't hang up connections in these two cases though -- we need to look at it more carefully to avoid flapping, and we likely need to wait til 0.1.1.x is obsolete. svn:r6712	2006-07-04 03:31:27 +00:00
Roger Dingledine	4e4cc9aa27	lower the number of seconds before we yell about clock jump. and make the yelling only happen if you're a server. svn:r6625	2006-06-15 09:03:15 +00:00
Roger Dingledine	0bfef523df	simplify the tortls api: we only support being a "server", that is, even tor clients do the same sort of handshake. this has been true for years, so it's best to get rid of the stale code. svn:r6557	2006-06-07 06:10:54 +00:00
Nick Mathewson	853e2d99b6	Add a new warning to our "warn a lot" list: unused parameters. This means we have to explicitly "use" unuseds, but it can catch bugs. (It caught two coding mistakes so far.) svn:r6532	2006-06-04 22:42:13 +00:00
Roger Dingledine	48be472e4f	clean up a comment svn:r6508	2006-05-28 16:07:44 +00:00
Roger Dingledine	27624a3024	stop telling people that "tor -h" will help them in any way. svn:r6447	2006-05-08 04:28:49 +00:00
Roger Dingledine	3c86402cc2	petty cleanups svn:r6421	2006-04-25 07:00:04 +00:00
Roger Dingledine	07ff409876	no need to escape the address for our connections -- they are always IP addresses. svn:r6389	2006-04-16 22:34:00 +00:00
Peter Palfrader	beb9e0721a	Stop assuming every authority is a v1 authority svn:r6377	2006-04-10 21:29:29 +00:00
Roger Dingledine	12d461a245	make DirFetchPeriod and StatusFetchPeriod truly obsolete. svn:r6373	2006-04-10 20:16:46 +00:00
Roger Dingledine	6f08d121d9	Refactor and consolidate addr/exit policies into a new policies.c. Fix some minor bugs and memory leaks along the way. svn:r6246	2006-03-27 02:25:34 +00:00
Roger Dingledine	51a3981d10	stop caching the v1 directory so often. svn:r6226	2006-03-22 06:18:27 +00:00
Roger Dingledine	1db263ac3c	stop writing the "router.desc" file, ever. nothing uses it anymore. svn:r6224	2006-03-22 03:45:17 +00:00
Roger Dingledine	a3329036a8	Bugfix: looks like clients since 0.1.1.10-alpha have been expiring connections whenever 5 minutes pass and they do have circuits on them. svn:r6213	2006-03-21 21:58:00 +00:00
Roger Dingledine	d1d0813cf3	Allow non-printable characters for exit streams (both for connecting and for resolving). Now we tolerate applications that don't follow the RFCs. But continue to block malformed names at the socks side. svn:r6193	2006-03-19 03:55:48 +00:00
Roger Dingledine	903183ea28	if we as a directory mirror don't know of any v1 directory authorities, then don't try to cache any v1 directories. svn:r6162	2006-03-15 00:10:13 +00:00
Roger Dingledine	499eeced44	when event_add or event_del fail, tell us why. svn:r6156	2006-03-13 19:33:46 +00:00
Nick Mathewson	bd8ffccae7	More cleanups noticed by weasel; also, remove macros that nobody uses. svn:r6143	2006-03-12 23:31:16 +00:00
Nick Mathewson	474c60b743	Cleanup on time-relaqted constants. New conventions: 1) Surround all constants by (parens), whether we'll be using them in a denominator or not. 2) Express all time periods as products (246060), not as multiplied-out constants (86400). 3) Comments like "(6060) / one hour /" are as pointless as comments like "c = a + b; / set c to the sum of a and b /". Remove them. 4) All time periods should be #defined constants, not given inline. 5) All time periods should have doxygen comments. 6) All time periods, unless specified, are in seconds. It's not necessary to say so. To summarize, the old (lack of) style would allow: #define FOO_RETRY_INTERVAL 6060 /* one hour (seconds) / next_try = now + 3600; The new style is: /* How often do we reattempt foo? / #define FOO_RETRY_INTERVAL (6060) next_try = now + RETRY_INTERVAL; svn:r6142	2006-03-12 22:48:18 +00:00
Roger Dingledine	ef447507ff	a better clean-up svn:r6139	2006-03-12 20:51:02 +00:00
Roger Dingledine	a98b25137c	and another fix svn:r6138	2006-03-12 20:48:59 +00:00
Roger Dingledine	e11f900a2a	stop printing a log message at every iteration through the event loop when holding open a conn for flushing but it doesn't want to flush any more bytes yet. svn:r6114	2006-03-09 06:34:33 +00:00
Roger Dingledine	44107f6ec4	Implement NEWNYM. Nick, did I do a bad thing? svn:r6105	2006-03-09 00:18:16 +00:00
Roger Dingledine	0f39033b9f	clean up typo svn:r6103	2006-03-09 00:10:28 +00:00
Peter Palfrader	0bab094d5d	Explain why we only expire open connections svn:r6015	2006-02-14 17:30:04 +00:00
Peter Palfrader	84295f9f43	Do not mark connections obsolete before they have done their TLS handshake or are at least 60 seconds old svn:r6013	2006-02-14 04:23:05 +00:00
Roger Dingledine	aa63a84fe1	the things we do for our windows users. i hope they appreciate it. svn:r6004	2006-02-13 09:37:53 +00:00
Roger Dingledine	5f051574d5	Happy new year! svn:r5949	2006-02-09 05:46:49 +00:00
Roger Dingledine	fd0fcdf17c	stop calling it a "libevent poll" -- the word "poll" has other meaning in this context that are confusing. svn:r5936	2006-02-09 03:09:52 +00:00
Roger Dingledine	555a64e06d	as soon as we've fetched some more directory info, that's time to think about downloading more server descriptors. this way we don't have a 10 second pause in initial bootstrapping. svn:r5916	2006-02-05 03:42:34 +00:00
Roger Dingledine	a53a73a782	forward-port the part where ordinary users try to fetch directories less often. not critical but might as well stay in sync with stable. svn:r5910	2006-02-05 01:57:07 +00:00
Roger Dingledine	686508a04a	don't try to upload hidden service descriptors until we have established a circuit. svn:r5884	2006-02-01 02:19:46 +00:00
Roger Dingledine	8fc44169e5	only start testing reachability once we've established a circuit. this will make startup on dirservers less noisy. it may also break things in subtle ways. svn:r5878	2006-01-29 01:11:41 +00:00
Roger Dingledine	35f91db15f	a slightly more useful message when you get a sighup svn:r5869	2006-01-26 19:11:06 +00:00
Roger Dingledine	de13ddd26f	Stop complaining loudly whenever some poor client falls off the network before we finish writing to him. svn:r5850	2006-01-23 09:23:04 +00:00
Roger Dingledine	54a7285e99	oh hey. we were hanging up on every tor client because he was obsolete as soon as he started. big oops. svn:r5807	2006-01-11 22:34:07 +00:00
Nick Mathewson	8907391ad6	Fix wide lines svn:r5793	2006-01-11 04:04:42 +00:00
Roger Dingledine	7d1f675c85	entry nodes are now entry guards. this is our last easy chance for a wholesale change. heave ho. svn:r5782	2006-01-10 22:42:44 +00:00
Roger Dingledine	c8e6003412	balance the reachability testing so a smidgen of it happens every 10 seconds. this way we don't try to do 500 tls's at once every 20 minutes. svn:r5763	2006-01-10 07:21:01 +00:00
Roger Dingledine	1dd8ebf615	bugfix: we were leaving open duplicate connections to other ORs for a week, rather than closing them once we detect a duplicate. also, avoid some duplicate mark-for-closes in connection-housekeeping. svn:r5752	2006-01-07 03:56:56 +00:00
Roger Dingledine	af54b73985	and get the log arguments right svn:r5747	2006-01-07 01:43:09 +00:00
Roger Dingledine	ba339b8a4d	a more correct log message svn:r5746	2006-01-07 01:41:17 +00:00
Roger Dingledine	e9e7dc176c	Some tor servers process billions of cells in a matter of days. These statistics need to be uint64_t's. svn:r5686	2005-12-31 08:09:26 +00:00
Roger Dingledine	dbd7b97eff	helper nodes are dead. long live entry nodes. (config options EntryNodes and StrictEntryNodes still not implemented.) svn:r5673	2005-12-28 09:07:31 +00:00

Nick Mathewson	ce71b17224	Clean fake_status a bit. Switch from has_fetched_directory to have_minimum_dir_info, and make the latter function smarter. svn:r5591	2005-12-15 20:44:15 +00:00
Nick Mathewson	1af630d32c	Bite the bullet and limit all our source lines to 80 characters, the way IBM intended. svn:r5582	2005-12-14 20:40:40 +00:00
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	39265dd72e	In my private little universe, terminals are still 80 columns. Impose a 160-character-per-line limit; this will creep down. svn:r5548	2005-12-09 05:37:26 +00:00
Roger Dingledine	8730190914	when we're checking reachability, make it clearer in the logs what to expect. svn:r5538	2005-12-08 21:12:47 +00:00
Nick Mathewson	77a494dd55	Expunge remaining places where we used "tree" to mean "associative array". svn:r5490	2005-12-03 02:21:31 +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
Roger Dingledine	f94f4c1686	when event_add or event_del fail, tell us why. (nick, do i have my libevent strerror dance moves correct?) svn:r5462	2005-11-26 09:37:00 +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

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

Nick Mathewson	cdc912714e	I love the smell of C in the morning. Make router-download rules smarter (download more so long as we dont duplicate existing requests; relaunch at staggered intervals); relaunch one a minute or on failure; reset 60 minutes; always open 3 requests if we can; add authority opinion to networkstatus; make naming rule correct. There is a remaining bug where we retry servers too quickly; We need to look at that harder. svn:r5110	2005-09-22 06:34:29 +00:00

Nick Mathewson	e3adcbdb95	Big commit: clients start downloading and using network-statuses. Only caches need to get running-routers; nobody needs to parse, store, or use it. Same for the router-status line in the directories. Add many #if 0's that can get removed once I'm convinced they don't contain anything I'm forgetting. Start all newly-parsed routers as non-running and non-valid; update them from the list of network statuses. Update all routers when a new networkstatus comes in. After 3 tries for a networkstatus, clients give up until they're told to try again. "Let's get those missles ready to DESTROY THE UNIVERSE!" -TMBG svn:r5063	2005-09-14 21:09:25 +00:00

Replace it with one to see whether caches support v2 stuff. - Parse, cache, and serve network-status objects properly. - Serve compressed groups of router descriptors.

Roger Dingledine	d2400a5afd	Introduce a notion of 'internal' circs, which are chosen without regard to the exit policy of the last hop. Intro and rendezvous circs must be internal circs, to avoid leaking information. Resolve and connect streams can use internal circs if they want. New circuit pooling algorithm: make sure to have enough circs around to satisfy any predicted ports, and also make sure to have 2 internal circs around if we've required internal circs lately (with high uptime if we've seen that lately). Split NewCircuitPeriod config option into NewCircuitPeriod (30 secs), which describes how often we retry making new circuits if current ones are dirty, and MaxCircuitDirtiness (10 mins), which describes how long we're willing to make use of an already-dirty circuit. Once rendezvous circuits are established, keep using the same circuit as long as you attach a new stream to it at least every 10 minutes. (So web browsing doesn't require you to build new rend circs every 30 seconds.) Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND circ as necessary, if there are any completed ones lying around when we try to launch one. Re-instate the ifdef's to use version-0 style introduce cells, since there was yet another bug in handling version-1 style. We'll try switching over again after 0.0.9 is obsolete. Bugfix: when choosing an exit node for a new non-internal circ, don't take into account whether it'll be useful for any pending x.onion addresses -- it won't. Bugfix: we weren't actually publishing the hidden service descriptor when it became dirty. So we only published it every 20 minutes or so, which means when you first start your Tor, the hidden service will seem broken. svn:r3360	2005-01-17 18:13:09 +00:00

Nick Mathewson	57536f138a	Fetch running-routers. Split logic to initiate dirfetch, running-routers fetch, and descriptor post. arma: There are some XXXs here that raise design questions which we should solve before the next release. The biggest problem is this: Right now, the directory is about 50X as large as running-routers uncompressed, and about 36X as large compressed. Assuming: - everybody gets the compressed version of everything, - everybody gets cached directories from random dirservers and uncached r-r from authdirservers - everybody downloads r-r at the same rate they now download dirs, then using r-r from will increase authdirserver directory bandwidth usage if there are significantly more caches than authdirservers. I think it's safe to leave this in for now, since there aren't 3x36 caching dirservers, but we should make everybody with a dirport cache running-routers soon. But I could be wrong. svn:r2872	2004-11-14 21:46:40 +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

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	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

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

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.

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	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	b097aa3288	per-second cell statistics to help with profiling svn:r140	2002-11-24 08:45:54 +00:00
Roger Dingledine	ab0aee04d9	added OnionsPerSecond to prevent create flooding first cut, probably needs more playing with svn:r137	2002-11-23 08:49:03 +00:00

Roger Dingledine	bf53852a00	cleanup and a variety of bugfixes svn:r132	2002-10-02 22:54:20 +00:00
Roger Dingledine	e3fd91755d	preemptive bugfix svn:r129	2002-10-02 04:07:33 +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	081e8969db	catch hup to reload directory/router list svn:r121	2002-09-28 01:40:11 +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	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	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	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	ddc2b69a28	onion proxies now work (i think) svn:r96	2002-09-04 06:29:28 +00:00

Roger Dingledine	27adc0f20b	enforce maxconn; bugfix to not tear down the parent when we hit maxconn svn:r86	2002-09-03 18:36:40 +00:00
Roger Dingledine	3a7f3ba348	cleanup: don't use size_t when you mean int size_t is what you get back from sizeof(). no more, no less. svn:r80	2002-08-24 04:59:21 +00:00
Roger Dingledine	08adaa4b46	cleaned up new_route() now it deals gracefully with too few connected routers (i think) svn:r77	2002-08-23 03:35:44 +00:00
Matej Pjafjar	01aadefbfc	Changed crypto calls to go through common/crypto.[hc] instead of calling OpenSSL directly. svn:r76	2002-08-22 07:30:03 +00:00
Roger Dingledine	cd0760ddda	Code cleaned up to be less noisy svn:r71	2002-07-22 04:08:37 +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
Bruce Montrose	be25ffd5d7	removed loglevel from global namespace. severity level is set using log() with a NULL format argument now. example: log(LOG_ERR,NULL); svn:r44	2002-07-12 18:14:17 +00:00
Bruce Montrose	d00c39231d	integrated use of getoption() into OR. removed getargs() and getconfig(). svn:r43	2002-07-12 17:12:08 +00:00
Matej Pjafjar	f07ade3046	getrouters() changed so that a router ignores its own entry in the router list svn:r34	2002-07-10 12:35:59 +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	b86fecbf47	general cleanup svn:r29	2002-07-05 06:27:23 +00:00
Roger Dingledine	66c6f2231e	patch to fix running the program only as an op svn:r27	2002-07-03 17:30:59 +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	b503d4c6d6	made 'app' connection be 'exit' connection general cleanup, particularly in buffers.c svn:r17	2002-06-30 07:37:49 +00:00
