Arceliar	818eca90db	fix nil pointer deref if searches fail, block dial until a search exceeds or a timeout passes (todo: replace timer with context)	2019-06-29 16:10:02 -05:00
Arceliar	784acba823	I think this fixes the concurrent map read/write panic	2019-06-29 12:14:44 -05:00
Arceliar	e88bef35c0	get rid of old buffered session packets	2019-06-28 20:02:58 -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	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
