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 Anderson	78654ee1bd	cmd/tailscale: switch to an ffcli based CLI. Two commands for now, `up` and `netcheck`. The commands and the flags they take will change a bunch in the future, but this is good enough to launch on parity with relaynode. Signed-Off-By: David Anderson <dave@natulte.net>	5 years ago

Brad Fitzpatrick	14559340ee	Start of netcheck package & including network state in Hostinfo. * adds new packet "netcheck" to do the checking of UDP, IPv6, and nearest DERP server, and the Report type for all that (and more in the future, probably pulling in danderson's natprobe) * new tailcfg.NetInfo type * cmd/tailscale netcheck subcommand (tentative name, likely to change/move) to print out the netcheck.Report.

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.

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.)
