Previously, the new disco keys entering the client via TSMP was routed into controlClient to allow for deduplication and filtering of disco keys and avoid control overwriting an active TSMP learned key with a stale key. A system supporting multiple disco keys was introduced to allow these keys living side by side, along side a system for selecting an active egress key with a bias towards keys learned via TSMP. On ingress any known key is accepted. This PR makes the switch to key routing, by sending new TSMP learned disco keys directly into the userspace engine and in turn magicsock, removing the need for a full layer of deduplication in the controlClient. Additionally, the system that previously fully reconfigured clients on disco key updates coming from control is now using an optimistic handshake througha newly introduced wireguard-go method, ScheduleHandshakeOnUserSend implemented in: https://github.com/tailscale/wireguard-go/pull/81 What this PR does not do is revert the mapSession back to being single writer. Bringing the mapSession back to this state is desired, however to ensure the plumbing is done right and easier to reason about, that will be done in a separate PR.

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.
