Simon Law 00699abdfb tailcfg,tailcfg/{nodecap,selfcap}: split capability constants to their own packages (#20639)
Package tailcfg defines the types and constants used by the Tailscale
protocol, but since everything is all in one package, it’s difficult
to sift through the docs: https://pkg.go.dev/tailscale.com/tailcfg

We define and enumerate capabilities as string constants for
tailcfg.NodeCapability and tailcfg.PeerCapability. This PR extracts
them into their own packages:

- tailcfg.CapabilityFileSharing becomes nodecap.FileSharing
- tailcfg.NodeAttrOnlyTCP443 becomes nodecap.OnlyTCP443
- tailcfg.PeerCapabilityTaildrive becomes peercap.Taildrive

We originally intended for CapabilityFoo to grant an entitlement or
permission for Foo, and for NodeAttrBar to configure Bar in the
nodeAttrs section of the policy file. However, there was no technical
enforcement of this convention, so new capabilities have used the
NodeAttr prefix regardless of meaning. Therefore, this PR unifies
tailcfg.CapabilityFoo and tailcfg.NodeAttrBar into a single package as
nodecap.Foo and nodecap.Bar.

Ran `go fix -inline ./...` and committed the changes that replaced
uses of the tailcfg aliases with the authoritative ones.

Updates #20259

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:

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 1.26. (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.
