updates tailscale/corp#48949 updates tailscale/corp#25687 Credit to Keita Sode (SYZD Research) and Jaeyeong Lee for the initial report. The macsys credential file is written 0640 and chowned to the admin group so that members of that group, and only those members, can read the LocalAPI token. Several failure modes silently defeated that. The mode passed to OpenFile is masked by the process umask, so a umask of 0027 or 0077 leaves the file 0600 and no administrator can read the token. Set the mode explicitly after creating the file. Do this only for macsys; the sandboxed variant's mode is deliberately left alone rather than widened back up to 0666. The gid was hardcoded to 80. Resolve the admin group by name instead, matching how admin membership is determined elsewhere - ipnauth's isLocalAdmin resolves "admin" via util/groupmember - and keep 80 as a fallback so a failed lookup behaves as it did before. This also makes the code correct on a host where "admin" is not gid 80. The corresponding GUI client changes to modify the GUI spawned CLI behaviour can be found here: https://github.com/tailscale/corp/pull/50603 Change-Id: I73ddc77b3b9551b7169edf71e35385752893decd Signed-off-by: Jonathan Nobels <jonathan@tailscale.com>
Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms 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. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.27. (While we build releases with our Go fork, its use is not required.)
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.
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.
See commit-messages.md (or skim git log) for our commit message style.
