By default, Windows sets the SIO_UDP_CONNRESET and SIO_UDP_NETRESET options on created UDP sockets. These behaviours make the UDP socket ICMP-aware; when the system gets an ICMP message (e.g. an "ICMP Port Unreachable" message, in the case of SIO_UDP_CONNRESET), it will cause the underlying UDP socket to throw an error. Confusingly, this can occur even on reads, if the same UDP socket is used to write a packet that triggers this response. The Go runtime disabled the SIO_UDP_CONNRESET behavior in 3114bd6, but did not change SIO_UDP_NETRESET–probably because that socket option isn't documented particularly well. Various other networking code seem to disable this behaviour, such as the Godot game engine (godotengine/godot#22332) and the Eclipse TCF agent (link below). Others appear to work around this by ignoring the error returned (anacrolix/dht#16, among others). For now, until it's clear whether this ends up in the upstream Go implementation or not, let's also disable the SIO_UDP_NETRESET in a similar manner to SIO_UDP_CONNRESET.

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 1.22. (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 git log for our commit message style. It's basically the same as
Go's style.
