Avery Pennarun a8766815a4 ipn: cc.Login(noninteractive) at start even if WantRunning=false. We were not properly initializing controlclient at startup, if Prefs.WantRunning was initially false. This originally would cause the state machine to get stuck in NewState, but an earlier erroneous change tried to make it get stuck in NeedsLogin instead, which is incorrect; NeedsLogin means we need interactive login, which is not true. The correct fix is to not get it stuck. While we're here: - Add a bunch of comments to explain how these work. - Unexport the Status.state var from controlclient. There has not been any need for outsiders to inspect it for a long time; it's needed only by unit tests. - Remove a very suspicious check from AuthCantContinue that its self pointer != nil. - Remove an extremely suspicious "defer b.stateMachine()" from Start(). There is no need to run the state machine when nothing has happened yet; any apparent need for this is a sign of some other bug.

Tailscale

https://tailscale.com

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale client code and the tailscaled daemon and tailscale CLI tool. The tailscaled daemon runs primarily on Linux; it also works to varying degrees on FreeBSD, OpenBSD, Darwin, and Windows.

The Android app is at https://github.com/tailscale/tailscale-android

Using

We serve packages for a variety of distros 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 that are not open source.

Building

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.

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.16) in module mode. It might work in earlier Go versions or in GOPATH mode, but we're making no effort to keep those working.

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.
