Brad Fitzpatrick	fe0051fafd	wgengine/magicsock: expand AddrSet.addrs comment	5 years ago
David Anderson	2839854994	wgengine/magicsock: never set a DERP server as a roamAddr. DERP traffic is asymmetric by design, with nodes always sending to their peer's home DERP server. However, if roamAddr is set, magicsock will always push data there, rather than let DERP server selection do its thing, so we end up accidentally creating a symmetric flow.

Brad Fitzpatrick	2cff9016e4	net/dnscache: add overly simplistic DNS cache package for selective use I started to write a full DNS caching resolver and I realized it was overkill and wouldn't work on Windows even in Go 1.14 yet, so I'm doing this tiny one instead for now, just for all our netcheck STUN derp lookups, and connections to DERP servers. (This will be caching a exactly 8 DNS entries, all ours.) Fixes #145 (can be better later, of course)	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.)
