David Crawshaw	c576a57067	wgengine: avoid holding any locks during HandshakeDone Because wgLock is held while some wireguard-go methods run, trying to hold wgLock during HandshakeDone potentially creates lock cycles between wgengine and internals of wireguard-go. Arguably wireguard-go should call HandshakeDone in a new goroutine, but until its API promises that, don't make any assumptions here. Maybe for #110.

David Crawshaw	7a3be96199	wgengine: add pinger to generate initial spray packets For 3 seconds after a successful handshake, wgengine will send a ping packet every 300ms to its peer. This ensures the spray logic in magicsock has something to spray. Signed-off-by: David Crawshaw <crawshaw@tailscale.com>	5 years ago
David Crawshaw	a6ad3c46e2	magicsock: spray some normal packets after a handshake In particular, this is designed to catch the case where a HandshakeInitiation packet is sent out but the intermediate NATs have not been primed, so the packet passes over DERP. In that case, the HandshakeResponse also comes back over DERP, and the connection proceeds via DERP without ever trying to punch through the NAT. With this change, the HandshakeResponse (which was sprayed out and so primed one NAT) triggers an UpdateDst, which triggers the extra spray logic. (For this to work, there has to be an initial supply of packets to send on to a peer for the three seconds following a handshake. The source of these packets is left as a future exercise.)

David Crawshaw	4ebc0fa70f	wgengine: incremental update of peers on network map change This is the first, and easier, part of incremental wireguard-go reconfiguration. It means that a new node appearing on the network does not cause all existing nodes to re-handshake with the other nodes they are talking to. (This code has been running on hello.ipn.dev for a few weeks and peers have successfully reconnected to it through many network map updates.)

David Anderson	5c2deb66be	wgengine: remove MTU TODO. The MTU is currently set when creating the tun device, elsewhere in the code.
