Brad Fitzpatrick	34d2f5a3d9	tailcfg: add Endpoint, EndpointType, MapRequest.EndpointType Track endpoints internally with a new tailcfg.Endpoint type that includes a typed netaddr.IPPort (instead of just a string) and includes a type for how that endpoint was discovered (STUN, local, etc). Use []tailcfg.Endpoint instead of []string internally. At the last second, send it to the control server as the existing []string for endpoints, but also include a new parallel MapRequest.EndpointType []tailcfg.EndpointType, so the control server can start filtering out less-important endpoint changes from new-enough clients. Notably, STUN-discovered endpoints can be filtered out from 1.6+ clients, as they can discover them amongst each other via CallMeMaybe disco exchanges started over DERP. And STUN endpoints change a lot, causing a lot of MapResposne updates. But portmapped endpoints are worth keeping for now, as they they work right away without requiring the firewall traversal extra RTT dance. End result will be less control->client bandwidth. (despite negligible increase in client->control bandwidth) Updates tailscale/corp#1543 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	4 years ago

David Anderson	19eca34f47	wgengine/router: fix FreeBSD configuration failure on the v6 /48. On FreeBSD, we add the interface IP as a /48 to work around a kernel bug, so we mustn't then try to add a /48 route to the Tailscale ULA, since that will fail as a dupe.

Josh Bleecher Snyder	ba72126b72	wgengine/magicsock: remove RebindingUDPConn.FakeClosed It existed to work around the frequent opening and closing of the conn.Bind done by wireguard-go. The preceding commit removed that behavior, so we can simply close the connections when we are done with them. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
Josh Bleecher Snyder	69cdc30c6d	wgengine/wgcfg: remove Config.ListenPort We don't use the port that wireguard-go passes to us (via magicsock.connBind.Open). We ignore it entirely and use the port we selected. When we tell wireguard-go that we're changing the listen_port, it calls connBind.Close and then connBind.Open. And in the meantime, it stops calling the receive functions, which means that we stop receiving and processing UDP and DERP packets. And that is Very Bad. That was never a problem prior to `b3ceca1dd7`, because we passed the SkipBindUpdate flag to our wireguard-go fork, which told wireguard-go not to re-bind on listen_port changes. That commit eliminated the SkipBindUpdate flag. We could write a bunch of code to work around the gap. We could add background readers that process UDP and DERP packets when wireguard-go isn't. But it's simpler to never create the conditions in which wireguard-go rebinds. The other scenario in which wireguard-go re-binds is device.Down. Conveniently, we never call device.Down. We go from device.Up to device.Close, and the latter only when we're shutting down a magicsock.Conn completely.

David Anderson	27a1a2976a	wgengine/router: add a CallbackRouter shim. The shim implements both network and DNS configurators, and feeds both into a single callback that receives both configs. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
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.

David Anderson	90f82b6946	net/dns/resolver: add live reconfig, plumb through to ipnlocal.

Brad Fitzpatrick	7f174e84e6	net/interfaces: remove mutating methods, add EqualFiltered instead Now callers (wgengine/monitor) don't need to mutate the state to remove boring interfaces before calling State.Equal. Instead, the methods to remove boring interfaces from the State are removed, as is the reflect-using Equal method itself, and in their place is a new EqualFiltered method that takes a func predicate to match interfaces to compare. And then the FilterInteresting predicate is added for use with EqualFiltered to do the job that that wgengine/monitor previously wanted. Now wgengine/monitor can keep the full interface state around, including the "boring" interfaces, which we'll need for peerapi on macOS/iOS to bind to the interface index of the utunN device.
