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.
