Nick Mathewson	1e5f457461	Fix most DOCDOCs remaining and/or added by redox. ... svn:r17734	2008-12-22 17:53:04 +00:00
Nick Mathewson	1725c0c8a5	Add DOCDOC comments for all undocumented functions. Add missing *s to other comments so that they will get recognized as doxygen. ... svn:r17729	2008-12-22 14:56:28 +00:00
Nick Mathewson	bf80e2df3f	Replace calls to time(NULL) that occur on the order of once per read, one per write, or once per cell with calls to a function that looks at a cached value of time. This is tricksy to benchmark, since it will only help on systems where time() is a syscall and syscalls are relatively slow. ... svn:r17690	2008-12-18 17:19:04 +00:00
Nick Mathewson	122170c1d3	Downlgrade tweak, and answer lots of XXX021s. No actual code fixes in this patch. ... svn:r17686	2008-12-18 16:11:24 +00:00
Nick Mathewson	ecaee1d927	Remove fixed xxx020s; downgrade unfixed ones. ... (The unfixed ones are being downgraded to regular XXXs mainly on the rationale that they don't seem to be exploding Tor, and they were apparently not showstoppers for 0.2.0.x-final.) svn:r17682	2008-12-18 16:11:03 +00:00
Nick Mathewson	7678ac5193	Move edge-only flags from connection_t to edge_connection_t. ... svn:r17643	2008-12-17 14:59:28 +00:00
Nick Mathewson	04ec7d1f98	Now that tor_assert is no longer using a broken force-to-boolean formulation, we can tor_assert a bitfield without a gcc compile error. ... svn:r17598	2008-12-11 20:28:50 +00:00
Nick Mathewson	ae33d3ead7	Apply rovv's fix for bug 824. ... svn:r16975	2008-09-26 15:30:26 +00:00
Nick Mathewson	8bc1536a9e	Add patch 4 from Karsten for proposal 121, slightly modified. Karsten should definitely re-review the bits I changed. ... svn:r16955	2008-09-24 14:44:29 +00:00
Roger Dingledine	4fd9880540	give rend_client_desc_here a slightly more accurate name ... svn:r16916	2008-09-16 10:26:15 +00:00

Roger Dingledine	2bde30efa6	read_to_buf should take an int *error_socket and return it. ... svn:r16909	2008-09-14 08:35:41 +00:00

Nick Mathewson	3f2b7078d2	Use warn_too_many_conns() when accept() fails with a resource limit. ... svn:r16751	2008-09-04 15:22:55 +00:00
Nick Mathewson	730f1b6d3f	Oops. Make warn_too_many_conns() actually work. ... svn:r16686	2008-08-29 17:01:15 +00:00
Nick Mathewson	fcf817f897	Switch global_identifier on connections to a 64-bit field and move it to connection_t. When procession onionskins, look up the connection by this field rather than by addr:port. This will keep us from dropping onionskins. How many dropped circuits are dropped because of this bug? ... svn:r16558	2008-08-15 13:55:01 +00:00
Nick Mathewson	30422b5df1	Rate-limit "too-many-sockets" messages; they can get needlessly verbose. ... svn:r16480	2008-08-09 15:35:37 +00:00

Nick Mathewson	960a0f0a99	r17641@31-33-44: nickm | 2008-08-05 16:07:53 -0400 ... Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types. Most of the Tor wire formats using these new types are in, but the code to generate and use it is not. This is a big patch. Let me know what it breaks for you. svn:r16435	2008-08-05 20:08:19 +00:00
Nick Mathewson	3ce6e2fba2	r17346@aud-055: nickm | 2008-07-24 15:37:19 +0200 ... Make generic address manipulation functions work better. Switch address policy code to use tor_addr_t, so it can handle IPv6. That is a good place to start. svn:r16178	2008-07-24 13:44:04 +00:00
Roger Dingledine	8fa912a8c5	If we close our OR connection because there's been a circuit ... pending on it for too long, we were telling our bootstrap status events "REASON=NONE". Now tell them "REASON=TIMEOUT". svn:r15369	2008-06-20 04:42:17 +00:00
Roger Dingledine	94dabd2c23	If you're using bridges, generate "bootstrap problem" warnings ... as soon as you run out of working bridges, rather than waiting for ten failures -- which will never happen if you have less than ten bridges. svn:r15368	2008-06-20 04:34:39 +00:00
Roger Dingledine	c6a94718cd	Directory authorities shouldn't complain about bootstrapping ... problems just because they do a lot of reachability testing and some of the connection attempts fail. svn:r15348	2008-06-18 07:34:04 +00:00
Roger Dingledine	8c85eef9b0	start sending "bootstrap problem" status events when we're having troubles ... reaching relays. svn:r15116	2008-06-11 01:14:23 +00:00

Roger Dingledine	baa3cea213	Start noticing and reporting bootstrapping failures too. It looks like ... we never bothered learning why OR conns fail, so next step is to add some infrastructure for that. svn:r15091	2008-06-09 18:32:43 +00:00

Roger Dingledine	bd959adcb7	patch from karsten: ... Resolved problems with (re-)fetching hidden service descriptors. Before, v0 descriptors were not fetched at all (fix on 0.2.0.18-alpha), re-fetching of v2 descriptors did not stop when a v0 descriptor was received (fix on 0.2.0.18-alpha), and re-fetching of v2 descriptors did not work in all cases (fix on 0.2.0.19-alpha). svn:r13540	2008-02-17 16:47:47 +00:00

Nick Mathewson	6e2946fb5d	r17949@catbus: nickm | 2008-02-06 13:21:12 -0500 ... Fix bandwidth bucked calculations again, I think. Bugfix on 0.1.2.x. Backport candidate. svn:r13406	2008-02-06 18:21:16 +00:00

Nick Mathewson	edf5e70784	r15891@tombo: nickm | 2008-01-12 19:20:24 -0500 ... Basic hacks to get TLS handshakes working: remove dead code; fix post-handshake logic; keep servers from writing while the client is supposed to be renegotiating. This may work. Needs testing. svn:r13122	2008-01-13 00:20:47 +00:00
Nick Mathewson	a7ef07b4bd	r15693@tombo: nickm | 2007-12-25 19:11:29 -0500 ... Here, have some terribly clever new buffer code. It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data. Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation. I've tested it out a little on peacetime, and it seems to work so far. If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module. svn:r12983	2007-12-26 00:12:08 +00:00

Nick Mathewson	c3a745951b	r16570@catbus: nickm | 2007-11-08 11:04:20 -0500 ... Keep track, for each OR connection, of the last time we added a non-padding cell to its outbuf. Use this timestamp, not "lastwritten" to tell if it is time to close a circuitless connection. (We can'tuse lastwritten, since lastwritten is updated when ever the connection flushes anything, and by that point we can no longer tell what is a padding cell and what is not.) svn:r12437	2007-11-08 16:19:07 +00:00

Nick Mathewson	b62d379f92	r15689@catbus: nickm | 2007-10-11 16:40:25 -0400 ... Fix bug 451. This was a nasty bug, so let's fix it twice: first, by banning recursive calls to connection_handle_write from connection_flushed_some; and second, by not calling connection_finished_flushing() on a closed connection.

Nick Mathewson	113367bc01	r14722@catbus: nickm | 2007-08-20 10:54:29 -0400 ... Add debugging warning to not abort in the case of bug 483.

Refactor entry guard status logic a lot; allow more factors [like not having a Guard flag or being listed in ExcludeNodes] to render a guard "unlisted" (now called "unusable"); track guard down status (now called "unreachable") separately from is_running. svn:r8519	2006-09-28 23:57:44 +00:00

Nick Mathewson	5cff4164a0	r7299@Kushana: nickm | 2006-08-10 01:08:58 -0700 ... Patch from Tup to add support for transparent AP connections: this basically bundles the functionality of trans-proxy-tor into the tor mainline. Now hosts with compliant pf/netfilter implementations can redirect TCP connections straight to Tor without diverting through SOCKS. svn:r7007	2006-08-10 09:01:37 +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	581795f41d	auth dir servers were only modifying a server's is_running field ... when they created a network status. so if nobody asked for a network status, they would never discover that any servers are is_running, so they could never build a circuit. svn:r6183	2006-03-18 01:24:04 +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	c66e4c4870	Flush more changes from sandbox ... - make clients cache directories and use them to seed their router lists at startup. 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".

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	7985f525ec	fix some bugs in assert_connection_ok ... svn:r1118	2004-02-24 22:33:30 +00:00
Roger Dingledine	f00dc6fe1e	last minute fix: don't early-flush non-tls streams ... e.g., this breaks directory service svn:r1033	2004-01-31 00:36:00 +00:00
Roger Dingledine	3516ae1a26	add an ap_conn connecting state; report connecting delay ... svn:r1011	2004-01-20 09:21:46 +00:00
Roger Dingledine	f5ebf4c712	push out a tls record's worth of data once you've got it ... svn:r1009	2004-01-20 02:14:51 +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	f3fdbadfdf	randomize the initial circ_id and stream_id, so an adversary who ... breaks in part-way through can't learn how many circs/streams have been made svn:r960	2003-12-28 04:46:09 +00:00

Roger Dingledine	d172fdd300	fix vicious bug in connection_ap_attach_pending that caused it to ... never work. fix vicious bug in choose_good_exit_server that caused it to *skip over* pending circuits, and look only at *non-pending circuits*, when choosing a good exit node for the new circuit. bugfix: remove incorrect asserts in circuit_get_newest() svn:r876	2003-12-03 09:50:02 +00:00
Roger Dingledine	02ec2cdb34	bugfix: we were writing to stderr even when it's closed ... svn:r868	2003-11-30 09:51:35 +00:00
Roger Dingledine	3818776f62	remove a conn_close_if_marked warning ... Nov 27 15:45:19.003 [warn] connection_write_to_buf(): write_to_buf failed. Closing connection (fd 42). Nov 27 15:45:19.010 [warn] conn_close_if_marked(): Conn (socket 42) still wants to flush. Losing 0 bytes! svn:r866	2003-11-30 09:35:26 +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
Roger Dingledine	1969c8a92f	client now survives going offline better ... fix badness in usage() if neither socksport nor orrport is defined, quit obsolete connection_flush_buf() svn:r780	2003-11-10 08:06:55 +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
Roger Dingledine	11a23fc280	clean up logging, allow user to specify log files ... If DebugLogFile is specified, log to it at -l debug If LogFile is specified, log to it at the -l from the commandline (default info) If no LogFile *and* not a Daemon, then log to stdout. 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	de6cbe53c0	some early bugfixes ... our log() conflicts with log(3) distribute only the correct files from doc/ and src/config/ sometimes laptops go back in time. i guess that's ok for now. and bump the version number because we're live. svn:r544	2003-10-07 16:30:05 +00:00

Roger Dingledine	2da3e4da0d	move connection_array accessors from main.c to connection.c ... (leave poll_array accessors in main.c) svn:r512	2003-09-30 19:06:22 +00:00

Roger Dingledine	4533da06c9	getting closer to having dirserv working ... we now add our own descriptor to the descriptor list and we rebuild the directory (and dump to disk) after receiving a POST svn:r509	2003-09-30 08:18:10 +00:00

Roger Dingledine	deac704399	connection_new() can't ever fail ... svn:r497	2003-09-27 07:28:44 +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	ed51df7453	bugfixes and note missing features ... deal with content-length headers better when reading http don't assume struct socks4_info is a packed struct fail the socks handshake if destip is zero flesh out conn_state_to_string() for dir conn fix typo (bug) in connection_handle_read() directory get is now called fetch, post is now upload reopen logs on sighup svn:r475	2003-09-21 06:15:43 +00:00
Roger Dingledine	078c5ab617	leave the socks handshake on the inbuf until it's complete ... this paves the way for supporting socks5 and other handshakes it also removes those pesky AP-only variables from connection_t also hacked a fix for a bug where some streams weren't ending properly -- maybe because marked connections weren't flushing properly? svn:r472	2003-09-18 08:11:31 +00:00
