George Jones 660a4608d2 feature/conn25: Update ConnectorTransitIPRequest handling (#18979)
Changed the mapping to store the transit IPs to be indexed by
peer IP rather than NodeID because the data path only has access
to the peer's IP. This change means that IPv4 transit IPs need to
be indexed by the peer's IPv4 address, and IPv6 transit IPs need to
be indexed by the peer's IPv6 address. It is an error if the peer
does not have an address of the same family as the transit IP.
It is also an error if the transit and destination IP families do
not match.

Added a check to ensure that the TransitIPRequest.App matches a
configured app on the connector.

Added additional TransitIPResponse codes to identify the new errors
and change the exsting use of the Other code to use it's own
specific code.

Added logging for the error cases, since they generally indicate that
a peer has constructed a bad request or that there is a config
mismatch between the peer and the local netmap.

Added a test framework for handleConnectorTransitIPRequest and moved
the existing tests into the framework and added new tests.

Fixes tailscale/corp#37143

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 1.25. (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.
