In #20775 (and the follow-up in #21471), we started installing quad-100 as the OS's primary resolver whenever cfg has hosts not covered by a split DNS route, so that sandboxed macOS clients could still answer them. However, that check was added to the generic split DNS gate rather than to the Apple-specific one, so it also applies on Windows, where dcfg.Hosts always carries every node's records and MagicDNSHostsUnrouted is set whenever MagicDNS is disabled. As a result, a Windows node with MagicDNS off and at least one split DNS route (or with MagicDNS on and a peer shared in from another tailnet) gets a catch-all NRPT rule pointing at quad-100, and all DNS traffic on the device is proxied through it instead of only the configured suffixes. The check is redundant for Apple platforms: iOS never takes the scoped path there, and sandboxed macOS only does so via scopeApple, which already requires !cfg.requiresPrimaryResolver(). This removes it from the generic gate, restoring the pre-1.104 behavior on Windows, and adds tests. Updates tailscale/corp#45534 Fixes #21863 Signed-off-by: Nick Khyl <nickk@tailscale.com>
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.
See commit-messages.md (or skim git log) for our commit message style.
