Arceliar	8af1a7086c	when a link becomes idle and packet are buffered that the link could send, send at least 65535 bytes worth instead of 1 packet, this reduces syscall overhead when small packets are sent through the network	2019-08-18 12:29:07 -05:00

Arceliar	46c5df1c23	when we abandon a link because we already have a connection to that peer, only wait for the connection to close if it's an *outgoing* link, otherwise incomming connection attempts can cause us to leak links	2019-08-13 18:49:49 -05:00

Arceliar	277da1fe60	make sure searches don't end if try to continue (in parallel) with nowhere left to send, but we just sent a search and are still waiting for a response	2019-08-11 13:11:14 -05:00
Arceliar	7a28eb787e	try to fix a few edge cases with searches that could lead them to ending without the callback being run or without cleaning up the old search info	2019-08-11 13:00:19 -05:00
Slex	589ad638ea	Implement feature from https://github.com/yggdrasil-network/yggdrasil-go/issues/488	2019-08-11 00:31:22 +03:00
Arceliar	5e81a0c421	Use a separate buffer per session for incoming packets, so 1 session that floods won't block other sessions	2019-08-07 18:08:31 -05:00
Arceliar	9ab08446ff	make sure the sessionInfo.recvWorker doesn't block if sinfo.recv somehow fills	2019-08-07 17:40:50 -05:00

Arceliar	790524bd1c	copy/paste old flowkey logic into a util function, add a struct of key and packet, make WriteNoCopy accept this instead of a slice	2019-08-06 19:25:55 -05:00
Arceliar	679866d5ff	have createSession fill the sessionInfo.cancel field, have Conn use Conn.session.cancel instead of storing its own cancellation, this should prevent any of these things from being both nil and reachable at the same time	2019-08-05 19:11:28 -05:00

Arceliar	1e6a6d2160	use session.cancel in the router to make blocking safe, reduce size of fromRouter buffer so the drops in the switch are closer to the intended front-drop behavior	2019-08-04 02:21:41 -05:00
Arceliar	7bf5884ac1	remove some lossy channel sends that should be safe to allow to block	2019-08-04 02:14:45 -05:00

Arceliar	144c823bee	just use a sync.Pool as the bytestore to not overcomplicate things, the allocations from interface{} casting don't seem to actually hurt in practice right now	2019-08-04 00:28:13 -05:00
