cf9880464b explicitly consider the session finished case, and make a note that we could fix the packet drop situation by making the Conn into an actor too 2019-08-23 22:36:59 -05:00

9835c63818 refactor things the router owns (dht, sessions, searches) into that struct, to make the ownership more explicit 2019-08-23 20:26:15 -05:00

b2cb1d965c avoid leaking sessions when no listener exists, or blocking if it's busy 2019-08-12 18:22:30 -05:00

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

9ab08446ff make sure the sessionInfo.recvWorker doesn't block if sinfo.recv somehow fills 2019-08-07 17:40:50 -05:00

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

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

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

Add SetSessionGatekeeper
This allows you to define a function which determines whether a session connection (either incoming or outgoing) is allowed based on the public key.
