Brad Fitzpatrick 1b89662eff ipn/ipnlocal: make peerapi listener on Android avoid the kernel
We intercept the peerapi port in netstack anyway, so there's no reason
the linux kernel on Android needs to know about it. It's only getting
in the way and causing problems for reasons we don't fully understand.
But we don't even need to understand it because it's not relevant
anymore.

Instead, provide a dummy net.Listener that just sits and blocks to
pacify the rest of the code that assumes it can be stuck in a
Listener.Accept call and call Listener.Close and Listener.Addr.

We'll likely do this for all platforms in the future, if/when we also
link in netstack on iOS.

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 on Linux, Windows and macOS, and to varying degrees on FreeBSD, OpenBSD, and Darwin. (The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.)

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

The Synology package is at https://github.com/tailscale/tailscale-synology

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 1.18) 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.
