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.

Updates #3475

Tailscale

https://tailscale.com

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale client code and the tailscaled daemon and tailscale CLI tool. The tailscaled daemon runs primarily on Linux; it also works to varying degrees on FreeBSD, OpenBSD, Darwin, and Windows.

The Android app is at https://github.com/tailscale/tailscale-android

Using

We serve packages for a variety of distros at https://pkgs.tailscale.com .

Other clients

The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers that are not open source.

Building

go install tailscale.com/cmd/tailscale{,d}

If you're packaging Tailscale for distribution, use build_dist.sh instead, to burn commit IDs and version info into the binaries:

./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled

If your distro has conventions that preclude the use of build_dist.sh, please do the equivalent of what it does in your distro's way, so that bug reports contain useful version information.

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.17) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.

Bugs

Please file any issues about this code or the hosted service on the issue tracker.

Contributing

PRs welcome! But please file bugs. Commit messages should reference bugs.

We require Developer Certificate of Origin Signed-off-by lines in commits.
