The conn25 extension's ExtraWireGuardAllowedIPs hook (Transit IPs) was only appended to wgcfg.Config.Peers in authReconfig. Now that outbound peer selection comes from the route manager's outbound table via the engine's PeerByIPPacketFunc (which, when installed, replaces wireguard-go's AllowedIPs trie lookup entirely) and lazily created peers get their allowed IPs from the route manager via the engine's peer config func, those extras never reached either path: outbound packets to Transit IPs matched no peer, and lazily created peers didn't accept inbound Transit IP sources. Teach the route manager a per-peer set of extra allowed IPs, staged by Mutation.SetExtraAllowedIPs. They appear in the outbound table and in PeerAllowedIPs (so both outbound routing and per-peer allowed source prefixes see them) but are excluded from the OS route set, preserving the hook's contract that the extras reach WireGuard but not the OS routing table. authReconfig now feeds the hook's results into the route manager and incrementally syncs any changed peers to the WireGuard device; the append to cfg.Peers remains only so Reconfig's full per-peer device sync doesn't strip the extras from active peers, and goes away with Config.Peers.

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.
