Brad Fitzpatrick 45a3de14a6 cmd/tailscaled, tailcfg, hostinfo: add flag to disable logging + support As noted in #5617, our documented method of blocking log.tailscale.io DNS no longer works due to bootstrap DNS. Instead, provide an explicit flag (--no-logs-no-support) and/or env variable (TS_NO_LOGS_NO_SUPPORT=true) to explicitly disable logcatcher uploads. It also sets a bit on Hostinfo to say that the node is in that mode so we can end any support tickets from such nodes more quickly. This does not yet provide an easy mechanism for users on some platforms (such as Windows, macOS, Synology) to set flags/env. On Linux you'd used /etc/default/tailscaled typically. Making it easier to set flags for other platforms is tracked in #5114. Fixes #5617 Fixes tailscale/corp#1475 Change-Id: I72404e1789f9e56ec47f9b7021b44c025f7a373a Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>		2 years ago

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 on Linux, Windows and macOS, and to varying degrees on FreeBSD, OpenBSD, and Darwin. (The Tailscale iOS and Android apps use this repo's code, but this repo doesn't contain the mobile GUI code.)

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

The Synology package is at https://github.com/tailscale/tailscale-synology

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 require the latest Go release, currently Go 1.19.

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.
