Joe Tsai d32700c7b2 util/deephash: specialize for netip.Addr and drop AppendTo support (#5402 ) There are 5 types that we care about that implement AppendTo: key.DiscoPublic key.NodePublic netip.Prefix netipx.IPRange netip.Addr The key types are thin wrappers around [32]byte and are memory hashable. The netip.Prefix and netipx.IPRange types are thin wrappers over netip.Addr and are hashable by default if netip.Addr is hashable. The netip.Addr type is the only one with a complex structure where the default behavior of deephash does not hash it correctly due to the presence of the intern.Value type. Drop support for AppendTo and instead add specialized hashing for netip.Addr that would be semantically equivalent to == on the netip.Addr values. The AppendTo support was already broken prior to this change. It was fully removed (intentionally or not) in #4870. It was partially restored in #4858 for the fast path, but still broken in the slow path. Just drop support for it altogether. This does mean we lack any ability for types to self-hash themselves. In the future we can add support for types that implement: interface { DeepHash() Sum } Test and fuzz cases were added for the relevant types that used to rely on the AppendTo method. FuzzAddr has been executed on 1 billion samples without issues. Signed-off-by: Joe Tsai joetsai@digital-static.net		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.
