David Anderson	96f008cf87	control/controlhttp: package to get a controlbase.Conn over HTTP(S). Updates #3488 Signed-off-by: David Anderson <danderson@tailscale.com>	3 years ago
David Anderson	d5a7eabcd0	control/controlbase: enable asynchronous client handshaking. With this change, the client can obtain the initial handshake message separately from the rest of the handshake, for embedding into another protocol. This enables things like RTT reduction by stuffing the handshake initiation message into an HTTP header. Similarly, the server API optionally accepts a pre-read Noise initiation message, in addition to reading the message directly off a net.Conn.

Brad Fitzpatrick	aae622314e	tailcfg, health: add way for control plane to add problems to health check So if the control plane knows that something's broken about the node, it can include problem(s) in MapResponse and "tailscale status" will show it. (and GUIs in the future, as it's in ipnstate.Status/JSON) This also bumps the MapRequest.Version, though it's not strictly required. Doesn't hurt.

Avery Pennarun	8a7d35594d	ipnlocal: don't assume NeedsLogin immediately after StartLogout(). Previously, there was no server round trip required to log out, so when you asked ipnlocal to Logout(), it could clear the netmap immediately and switch to NeedsLogin state. In v1.8, we added a true Logout operation. ipn.Logout() would trigger an async cc.StartLogout() and also immediately switch to NeedsLogin. Unfortunately, some frontends would see NeedsLogin and immediately trigger a new StartInteractiveLogin() operation, before the controlclient auth state machine actually acted on the Logout command, thus accidentally invalidating the entire logout operation, retaining the netmap, and violating the user's expectations. Instead, add a new LogoutFinished signal from controlclient (paralleling LoginFinished) and, upon starting a logout, don't update the ipn state machine until it's received.

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.

Instead, the certificate is loaded from the Windows local machine certificate store and uses its RSA public key to sign the RegisterRequest message. There is room to improve the flexibility of this feature in future and it is currently only tested on Windows (although Darwin theoretically works too), but this offers a reasonable starting place for now.
