Roger Dingledine	1c6def292b	remove dead code ... circuits no longer queue more cells when the windows are empty -- they simply don't package it from the buffer if they're not going to want it. we can restore this code later if we need to resume queueing. svn:r294	2003-05-20 06:53:10 +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
Nick Mathewson	1d1f46e40d	(possibly incorrect) code to make routers get resolved when they're ... inserted into the directory. Roger: If you can answer the question with your name on it, you may prevent a segfault before it happens. :) svn:r277	2003-05-08 12:32:30 +00:00

Nick Mathewson	445cd8f0f1	Decrease DH group length to 1024. (Roger, you may want to read section 1 of the IETF draft: a 1024-bit DH key probably reduces our cipher strength to ~80 bits.) ... svn:r269	2003-05-07 02:28:42 +00:00
Nick Mathewson	d0ff485e1b	More work on directories. Signed directories not yet tested. No support for checking sigs yet ... svn:r268	2003-05-07 02:13:23 +00:00

Roger Dingledine	ceafe12ed6	make reusing circuits work (and be the default) ... performance is better, but not by much. not sure why yet. svn:r153	2003-02-06 08:00:49 +00:00
Roger Dingledine	c35373a2cf	major overhaul: dns slave subsystem, topics ... on startup, it forks off a master dns handler, which forks off dns slaves (like the apache model). slaves as spawned as load increases, and then reused. excess slaves are not ever killed, currently. implemented topics. each topic has a receive window in each direction at each edge of the circuit, and sends sendme's at the data level, as per before. each circuit also has receive windows in each direction at each hop; an edge sends a circuit-level sendme as soon as enough data cells have arrived (regardless of whether the data cells were flushed to the exit conns). removed the 'connected' cell type, since it's now a topic command within data cells. at the edge of the circuit, there can be multiple connections associated with a single circuit. you find them via the linked list conn->next_topic. currently each new ap connection starts its own circuit, so we ought to see comparable performance to what we had before. but that's only because i haven't written the code to reattach to old circuits. please try to break it as-is, and then i'll make it reuse the same circuit and we'll try to break that. svn:r152	2003-01-26 09:02:24 +00:00

Roger Dingledine	9d3e80a589	use a rbtree for replay detection, rather than linear search ... when we had lots of new onions coming in, we were using 40% of our time searching through the tracked_onions linked list. svn:r150	2002-12-31 15:04:14 +00:00

Roger Dingledine	bd97deb919	onions expire after a day, not an hour ... this was a major faq, because it would fail with an error only on the *server* side when the client-side time was wrong. the client would simply not work. svn:r145	2002-12-03 07:06:13 +00:00

Roger Dingledine	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	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
