Brad Fitzpatrick db2436c7ff wgengine/magicsock: don't interrupt endpoint updates, merge all mutex into one Before, endpoint updates were constantly being interrupted and resumed on Linux due to tons of LinkChange messages from over-zealous Linux netlink messages (from router_linux.go) Now that endpoint updates are fast and bounded in time anyway, just let them run to completion, but note that another needs to be scheduled after. Now logs went from pages of noise to just: root@taildoc:~# grep -i -E 'stun\|endpoint update' log 2020/03/13 08:51:29 magicsock.Conn: starting endpoint update (initial) 2020/03/13 08:51:30 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:31 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:31 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:33 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:33 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") 2020/03/13 08:51:35 magicsock.Conn: starting endpoint update (link-change-minor) 2020/03/13 08:51:35 magicsock.Conn.ReSTUN: endpoint update active, need another later ("link-change-minor") Or, seen in another run: 2020/03/13 08:45:41 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:09 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:46:21 magicsock.Conn: starting endpoint update (link-change-major) 2020/03/13 08:46:37 magicsock.Conn: starting endpoint update (periodic) 2020/03/13 08:47:05 magicsock.Conn: starting endpoint update (periodic) Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		5 years ago

Tailscale

https://tailscale.com

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.
