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	654407dc6d	close long-dead connections in link.go instead of in switch.go, this is important in case a connection opens but never bothers to send even one switch message	2019-02-24 13:24:55 -06:00
Arceliar	bb3edd5e55	add the relevant error to the default logging when a connection is closed	2019-02-24 12:59:30 -06:00
Arceliar	042adb0516	make sure the only place traffic is ever dropped is in the switch. this currently disables the dedicated crypto workers	2019-02-23 00:07:00 -06:00

Arceliar	ebbe5f67ad	don't time out a link unless we were expecting an ack and didn't get one	2019-02-02 22:41:51 -06:00
Arceliar	b44a0f29f3	send an ack if we receive a packet and don't have any return traffic, keeping a legacy 4-second keep-alive in case there's no traffic at all to send (to be removed later, after nodes have upgraded), ideally we should either remove ReadTimeout or use it for the switch idle timeout instead	2019-02-02 22:18:55 -06:00

Arceliar	05962b2cbd	disable idle nodes in the switch instead of killing the connection entirely. this implementation is ugly, but i think it maybe works	2019-01-30 20:58:23 -06:00

Arceliar	12c0e019dc	only create one interface, but still opens duplicate connections before it catches this, so more work is needed	2019-01-22 21:16:41 -06:00
