David Anderson dbfc916273 derp: add short queues between reader and writer, drop on overload.
This avoids the server blocking on misbehaving or heavily contended
clients. We attempt to drop from the head of the queue to keep
overall queueing time lower.

Also:
 - fixes server->client keepalives, which weren't happening.
 - removes read rate-limiter, deferring instead to kernel-level
   global limiter/fair queuer.

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 support the latest Go release and any Go beta or release candidate builds (currently Go 1.13.x or 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.
