Josh Bleecher Snyder	b3ceca1dd7	wgengine/...: split into multiple receive functions ... Upstream wireguard-go has changed its receive model. NewDevice now accepts a conn.Bind interface. The conn.Bind is stateless; magicsock.Conns are stateful. To work around this, we add a connBind type that supports cheap teardown and bring-up, backed by a Conn. The new conn.Bind allows us to specify a set of receive functions, rather than having to shoehorn everything into ReceiveIPv4 and ReceiveIPv6. This lets us plumbing DERP messages directly into wireguard-go, instead of having to mux them via ReceiveIPv4. One consequence of the new conn.Bind layer is that closing the wireguard-go device is now indistinguishable from the routine bring-up and tear-down normally experienced by a conn.Bind. We thus have to explicitly close the magicsock.Conn when the close the wireguard-go device. One downside of this change is that we are reliant on wireguard-go to call receiveDERP to process DERP messages. This is fine for now, but is perhaps something we should fix in the future.

Josh Bleecher Snyder	7b907615d5	wgengine/wgcfg/nmcfg: remove dead code ... The call to appendEndpoint updates cpeer.Endpoints. Then it is overwritten in the next line. The only errors from appendEndpoint occur when the host/port pair is malformed, but that cannot happen. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago

Josh Bleecher Snyder	fe7c3e9c17	all: move wgcfg from wireguard-go ... This is mostly code movement from the wireguard-go repo. Most of the new wgcfg package corresponds to the wireguard-go wgcfg package. wgengine/wgcfg/device{_test}.go was device/config{_test}.go. There were substantive but simple changes to device_test.go to remove internal package device references. The API of device.Config (now wgcfg.DeviceConfig) grew an error return; we previously logged the error and threw it away. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
