* sign directories with the signing keyRoger Dingledine2003-05-07
| | | | svn:r274
* divorce circuit building from user connectionsRoger Dingledine2003-04-16
| | | | | | | | now we rebuild the circuit periodically (but only if it's been used), and we can further abstract it to do incremental circuit building, etc. svn:r233
* bugfix: make onion proxies actually obey their requested bandwidthRoger Dingledine2003-04-08

* Add magic to end of C files to make emacs happy; split test invocation into ↵Nick Mathewson2003-04-07

* fix rare race conditionRoger Dingledine2003-03-24
| | | | | | | | if the directory is remade while an OR is handshaking, the directory needs to become dirty again when the handshake succeeds svn:r215

* remove the mystery int32 from the or-to-or handshakeRoger Dingledine2003-03-07
| | | | | | | | thanks nick :) (note: this change breaks backward compatibility) svn:r169
* cleanup and a variety of bugfixesRoger Dingledine2002-10-02

* cleanupRoger Dingledine2002-09-28
| | | | | | | | | | 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
* directory servers in and functionalRoger Dingledine2002-09-26
| | | | | | | | proxies now periodically pull down an hourly-updated directory, and replace their router list with it if it parses correctly. svn:r112
* laying the groundwork for dynamic router listsRoger Dingledine2002-09-24
| | | | | | | | | | | | | | | | 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
* OP was hanging on first try if connect finishes too quicklyRoger Dingledine2002-09-20

* onion proxies now work (i think)Roger Dingledine2002-09-04

* port is now kept in host order except in sin_portRoger Dingledine2002-08-24
| | | | svn:r82
* cleanup: start enforcing hton and ntoh on stuff sent over the networkRoger Dingledine2002-08-24
| | | | | | | | | this is a checkpoint before i fix the fact that port is always kept in network order -- which makes no sense, because network order is different on different machines, which is the whole point. svn:r81
* Changed crypto calls to go through common/crypto.[hc] instead of calling ↵Matej Pjafjar2002-08-22

* Implemented congestion controlRoger Dingledine2002-07-18
| | | | | | | | | | | | | | | 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
* Implemented link padding and receiver token bucketsRoger Dingledine2002-07-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* put in the support for 'router twins'Roger Dingledine2002-07-08
| | | | | | | | | | | | | 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
* patch to fix running the program only as an opRoger Dingledine2002-07-03

* Integrated onion proxy into or/Roger Dingledine2002-07-02
| | | | | | | | | | | | | | | | | | | | | | | | | 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
