The macOS tailscaled DNS configurator only wrote /etc/resolver files, which can express split DNS but not a primary resolver. Teach it to configure a global resolver through the SystemConfiguration dynamic store using scutil when OSConfig has nameservers and no match domains. Let non-sandboxed macOS tailscaled follow Linux split DNS behavior when its OS configurator reports split DNS support. This avoids synthesizing an upstream default route from the machine's base DNS when the netmap did not provide one. Keep iOS and sandboxed macOS app builds on the existing Apple base-config path because those use NetworkExtension DNS settings rather than tailscaled's /etc/resolver configurator. Add tests for switching between split and global DNS, including cleanup of stale Tailscale-managed resolver files, removal of the dynamic-store global DNS key, and preservation of the sandboxed macOS behavior. RELNOTE: tailscaled on macOS now supports configuring global DNS resolvers. Updates #1338 Change-Id: I9b2b61f89750a5529fc0add1cd37b1b9a355db12 Signed-off-by: Maisem Ali <maisem@bold.dev>

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 1.26. (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.
