Arceliar	5df110ac79	make Dial block until the search finishes, and use it as such	2019-06-28 18:42:31 -05:00
Arceliar	29a0f8b572	some minor refactoring to dht callbacks and searches, work in progress	2019-06-25 19:31:29 -05:00
Arceliar	4b56849b08	fix issue with sessions dying and never being fixed	2019-06-10 22:09:12 -05:00
Arceliar	1addf08ccd	don't have Conn.Read return an error for temorary crypto failures from e.g. out of order packets, just drop the packet and keep blocking until there's usable traffic	2019-05-31 17:51:01 -05:00
Neil Alexander	9e086e70f0	Don't indefinitely block TUN/TAP reader goroutine when a conn error happens	2019-05-30 12:44:47 +01:00
Neil Alexander	0096d1ae3e	Re-add ICMPv6 packet too big handling	2019-05-29 20:16:17 +01:00
Arceliar	5ea864869a	don't spam searches for unused connections. todo: timeout old connections somehow	2019-05-23 20:27:52 -05:00
Arceliar	6469e39ff1	workaround to random timeouts	2019-04-26 22:42:05 -05:00
Arceliar	5d323861f0	properly fix the memory errors, it was caused by a function returning and PutBytes-ing a buffer before a worker had a chance to decrypt the buffer, so it would GetBytes the same buffer by dumb luck and then get an illegal overlap	2019-04-26 22:21:31 -05:00
Arceliar	01ea6d3d80	somehow this doesn't seem to deadlock or crash from buffer reuse (util.PutBytes), but I have no idea why it was doing that before and not now	2019-04-26 21:49:11 -05:00
Arceliar	15051b0a3c	Add deadline timers, keep searches alive until they complete (or the conn is closed) to keep Write from blocking forever	2019-04-26 19:31:47 -05:00
Arceliar	0059baf36c	add a newConn function that returns a pointer to a Conn with atomics properly initialized	2019-04-26 18:07:57 -05:00

Neil Alexander	47eb2fc47f	Break deadlock by creating session recv queue when session is created instead of repointing at search completion, also make expired atomic	2019-04-22 11:20:35 +01:00
Arceliar	5dada3952c	use a session worker to try to avoid mutex hell. compiles, but incomplete and doesn't work yet	2019-04-21 20:38:14 -05:00

Neil Alexander	781cd7571f	Fix race on tun conns, but still deadlocks if more than one connection is opened	2019-04-21 12:00:31 +01:00
Neil Alexander	79bcfbf175	Change some mutexes to atomics, change conns map to pointers, sort of works but seems to deadlock very easily	2019-04-21 11:50:41 +01:00
Neil Alexander	62621f2960	Some tweaks	2019-04-20 20:22:58 +01:00
