Apple and Android both implement their own login orchestration, coordinating preference updates, backend startup, and interative login. This requires the clients to understand details about the backend lifecycle and has led to duplicated logic and ordering issues. Android needs to avoid setting WantRunning=true via EditPrefs before calling Start, because doing so triggers Login on the existing control client, which Start then tears down, potentially canceling an in-flight registration before an authentication URL is returned (see https://github.com/tailscale/tailscale-android/commit/83057865e13b8f116a0871a3c6d6adf46f5c3d32). Apple has similar orchestration, including separate handling for auth keys, custom control servers, and reauth. This adds a LocalBackend helper that accepts optional masked prefs and an auth key, prepares the desired startup prefs, and initiates or resumes auth. This avoids unnecessary control client resets, preserves the existing control client and auth url when the login configuration hasn't changed, and ensures WantRunning is applied as part of Start when restarting the backend. This can be used for: -first time login with a custom control url or auth key -resuming an existing interactive login without losing auth url -retrying login without unnecessarily resetting the control client -reauth without restarting the backend A followup will expose this through localapi.

Tailscale
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:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
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 1.27. (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.
