Jonathan Nobels a714d402f2 net/netmon: add netmon hook for os-derived network change notifications
Update tailscale/corp#20677

While hunting down DNS issues, it was observed that
on apple platforms, w attempt to rebind to interfaces before they're
completely configured by the system.

The AF_ROUTE messages aren't lying, they're just not
taking into account other setup that has to happen,
notably the system setting the interface nameservers.
When we react based on the route updates, it's often
too quickly.  This happens frequently on wakes-from-sleep.

This replumbs netmon so that (optionally) rather than reacting to every
system message by checking for interesting changes, we
use that only to update our state, and recheck for interesting
network changes when we get a poke from the upper layers
indicating that a network change has 'completed'.  Notably on
Apple, NWPathMonitor seems to call us back at the correct
time(s) to check for potentially interesting interface changes
that have been observed via AF_ROUTE and to react to them.

This seems to reduce thrashing during network
transitions, and avoids some of the bad states we were
previously ending up in.

This is entirely opt in during the construction of the netmon
and will have no effect until/unless a specific client chooses
to use it.

Private WireGuard® networks made easy

Overview

This repository contains the majority of Tailscale's open source code. Notably, it includes the tailscaled daemon and the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows, macOS, and to varying degrees on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.

Other Tailscale repos of note:

For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.

Using

We serve packages for a variety of distros and platforms 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. The GUI wrappers on non-open source platforms are themselves not open source.

Building

We always require the latest Go release, currently Go 1.22. (While we build releases with our Go fork, its use is not required.)

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.

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.

See git log for our commit message style. It's basically the same as Go's style.
