wgcfg.Config.NetworkLogging carried the network flow logging identity inside the WireGuard config, where it was unrelated to WireGuard; it lived there mainly so that identity changes would defeat Reconfig's ErrNoChanges check and reach the netlog startup/shutdown logic. Remove the field and move the whole netlog lifecycle into a new feature/netlog package, installed on the engine via the new wgengine.HookNewNetLogger hook, like other feature/* packages. The logging identity now comes from LocalBackend's current netmap via the widened NetLogSource interface (replacing Engine.SetNetLogNodeSource), so nmcfg no longer parses audit log IDs into the config. The engine still calls the hook before its ErrNoChanges return and before router.Set (to capture initial packets), and again after router.Set (to capture final packets), preserving the previous ordering. Core wgengine no longer imports wgengine/netlog, so minimal builds drop it entirely. tailscaled keeps netlog via feature/condregister, and tsnet imports feature/condregister/netlog explicitly to keep netlog enabled by default in tsnet-based binaries (tsidp, k8s-operator). This is pulled out of a future change that removes wgcfg.Config.Peers, to make that PR smaller.

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 1.26. (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.
See commit-messages.md (or skim git log) for our commit message style.
