Brad Fitzpatrick a5d6c9d616 net/netns: optimize defaultRouteInterface a bit
It'll be called a bunch, so worth a bit of effort. Could go further, but not yet.
(really, should hook into wgengine/monitor and only re-read on netlink changes?)

Tailscale

Private WireGuard® networks made easy

Overview

This repository contains all the open source Tailscale code. It currently includes the Linux client.

The Linux client is currently cmd/relaynode, but will soon be replaced by cmd/tailscaled.

Using

We serve packages for a variety of distros at https://pkgs.tailscale.com .

Building

go install tailscale.com/cmd/tailscale{,d}

We only guarantee to support the latest Go release and any Go beta or release candidate builds (currently Go 1.14) 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.
