Add test coverage for the per-instance DisableLogTail feature: - TestEnableDisableRoundTrip: verify logtail.Enable/Disable toggle the global atomic bool correctly through multiple round-trips. - TestHandleDebugMessageDisableLogTail: verify handleDebugMessage fires the OnDisableLogTail callback, does NOT call envknob.SetNoLogsNoSupport, handles nil callback without panic, and does not fire the callback when DisableLogTail is false. - TestNoLogsNoSupportCombinesSources: verify LocalBackend.NoLogsNoSupport returns true when either the envknob or noLogsFromControl is set. - TestFlowLogsConflictCheck: verify that when logging is disabled and a netmap with CapabilityDataPlaneAuditLogs arrives, WantRunning is set to false with the correct error message (different for control-disabled vs user-disabled). - TestStartLockedClearsControlDisableLogTail: verify that Start clears noLogsFromControl and re-enables logtail. - TestProfileSwitchHeadscaleToTailscale: verify the full lifecycle of switching from a control server that disabled logging to one that requires flow logs. - TestGlobalNoLogsPreventReEnable: verify that when the global envknob is set, Start does NOT re-enable logtail, and the conflict check fires with the user-explicit error message.

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 1.25. (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.
