Denton Gentry	878a20df29	net/dns: add GetBaseConfig to CallbackRouter. Allow users of CallbackRouter to supply a GetBaseConfig implementation. This is expected to be used on Android, which currently lacks both a) platform support for Split-DNS and b) a way to retrieve the current DNS servers. iOS/macOS also use the CallbackRouter but have platform support for SplitDNS, so don't need getBaseConfig.

Brad Fitzpatrick	d3d503d997	ipn/ipnlocal: add HTTP/2 h2c server support to peerapi on non-mobile platforms To make ExitDNS cheaper. Might not finish client-side support in December before 1.20, but at least server support can start rolling out ahead of clients being ready for it. Tested with curl against peerapi.

Brad Fitzpatrick	adc5997592	net/tsdial: give netstack a Dialer, start refactoring name resolution This starts to refactor tsdial.Dialer's name resolution to have different stages: in-memory MagicDNS vs system resolution. A future change will plug in ExitDNS resolution. This also plumbs a Dialer into netstack and unexports the dnsMap internals. And it removes some of the async AddNetworkMapCallback usage and replaces it with synchronous updates of the Dialer's netmap from LocalBackend, since the LocalBackend has the Dialer too.

Brad Fitzpatrick	c37af58ea4	net/tsdial: move more weirdo dialing into new tsdial package, plumb Not done yet, but this move more of the outbound dial special casing from random packages into tsdial, which aspires to be the one unified place for all outbound dialing shenanigans. Then this plumbs it all around, so everybody is ultimately holding on to the same dialer. As of this commit, macOS/iOS using an exit node should be able to reach to the exit node's DoH DNS proxy over peerapi, doing the sockopt to stay within the Network Extension. A number of steps remain, including but limited to: * move a bunch more random dialing stuff * make netstack-mode tailscaled be able to use exit node's DNS proxy, teaching tsdial's resolver to use it when an exit node is in use.

Josh Bleecher Snyder	3fd5f4380f	util/multierr: new package github.com/go-multierror/multierror served us well.

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.

Josh Bleecher Snyder	07c09f470d	ipn/ipnlocal: do not shut down the backend halfway through TestStateMachine LocalBackend.Shutdown's docs say: > The backend can no longer be used after Shutdown returns. Nevertheless, TestStateMachine blithely calls Shutdown, talks some smack, and continues on, expecting things to work. Other uses of Shutdown in the codebase are as intended. Things mostly kinda work anyway, except that the wgengine.Engine has been shut down, so calls to Reconfig fail. Those get logged: > local.go:603: wgengine status error: engine closing; no status but otherwise ignored. However, the Reconfig failure caused one fewer call to pause/unpause than normal. Now the assertCalls lines match the equivalent ones earlier in the test. I don't see an obvious correct replacement for Shutdown in the context of this test; I'm not sure entirely what it is trying to accomplish. It is possible that many of the tests remaining after the prior call to Shutdown are now extraneous. They don't harm anything, though, so err on the side of safety and leave them for now.
