Before we introduced seamless, the "blocked" state was used to track: * Whether a login was required for connectivity, and therefore we should keep the engine deconfigured until that happened * Whether authentication was in progress "blocked" would stop authReconfig from running. We want this when a login is required: if your key has expired we want to deconfigure the engine and keep it down, so that you don't keep using exit nodes (which won't work because your key has expired). Taking the engine down while auth was in progress was undesirable, so we don't do that with seamless renewal. However, not entering the "blocked" state meant that we needed to change the logic for when to send LoginFinished on the IPN bus after seeing StateAuthenticated from the controlclient. Initially we changed the "if blocked" check to "if blocked or seamless is enabled" which was correct in other places. In this place however, it introduced a bug: we are sending LoginFinished every time we see StateAuthenticated, which happens even on a down & up, or a profile switch. This in turn made it harder for UI clients to track when authentication is complete. Instead we should only send it out if we were blocked (i.e. seamless is disabled, or our key expired) or an auth was in progress.

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 1.25. (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.
