Josh Bleecher Snyder 59026a291d wgengine/wglog: improve wireguard-go logging rate limiting Prior to wireguard-go using printf-style logging, all wireguard-go logging occurred using format string "%s". We fixed that but continued to use %s when we rewrote peer identifiers into Tailscale style. This commit removes that %sl, which makes rate limiting work correctly. As a happy side-benefit, it should generate less garbage. Instead of replacing all wireguard-go peer identifiers that might occur anywhere in a fully formatted log string, assume that they only come from args. Check all args for things that look like *device.Peers and replace them with appropriately reformatted strings. There is a variety of ways that this could go wrong (unusual format verbs or modifiers, peer identifiers occurring as part of a larger printed object, future API changes), but none of them occur now, are likely to be added, or would be hard to work around if they did.

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 primarily on Linux; it also works to varying degrees on FreeBSD, OpenBSD, Darwin, and Windows.

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

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 1.16) 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.

About Us

Tailscale is primarily developed by the people at https://github.com/orgs/tailscale/people. For other contributors, see:
