Adrian Dewhurst	3f456ba2e7	control/controlclient: return correct certificate ...

David Anderson	e0e677a8f6	net/dns: split out search domains and match domains in OSConfig. ... It seems that all the setups that support split DNS understand this distinction, and it's an important one when translating high-level configuration. Part of #953.

David Anderson	c16a926bf2	net/dns: set OSConfig.Primary. ... OS implementations are going to support split DNS soon. Until they're all in place, hardcode Primary=true to get the old behavior. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
David Anderson	bc4381447f	net/tstun: return the real interface name at device creation. ... This is usually the same as the requested interface, but on some unixes can vary based on device number allocation, and on Windows it's the GUID instead of the pretty name, since everything relating to configuration wants the GUID.

Josh Bleecher Snyder	7183e1f052	go.mod: update wireguard-go again ... To pick up https://go-review.googlesource.com/c/sys/+/307129. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
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.

Brad Fitzpatrick	d50406f185	ipn/ipnlocal: simplify loadStateLocked control flow a bit, restore logging ... The common Linux start-up path (fallback file defined but not existing) was missing the log print of initializing Prefs. The code was too twisty. Simplify a bit.

David Anderson	a39d2403bc	net/dns: disable NetworkManager and resolved configurators temporarily. ... They need some rework to do the right thing, in the meantime the direct and resolvconf managers will work out. The resolved implementation was never selected due to control-side settings. The networkmanager implementation mostly doesn't get selected due to unforeseen interactions with `resolvconf` on many platforms. Both implementations also need rework to support the various routing modes they're capable of. Signed-off-by: David Anderson <danderson@tailscale.com>	4 years ago
