Jonathan Nobels 16a920b96e safesocket: add isMacSysExt Check (#15192 ) fixes tailscale/corp#26806 IsMacSysApp is not returning the correct answer... It looks like the rest of the code base uses isMacSysExt (when what they really want to know is isMacSysApp). To fix the immediate issue (localAPI is broken entirely in corp), we'll add this check to safesocket which lines up with the other usages, despite the confusing naming.

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 1.23. (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.
