2026-01-23all: remove AUTHORS file and references to itWill Norris1-1/+1
This file was never truly necessary and has never actually been used in the history of Tailscale's open source releases. A Brief History of AUTHORS files --- The AUTHORS file was a pattern developed at Google, originally for Chromium, then adopted by Go and a bunch of other projects. The problem was that Chromium originally had a copyright line only recognizing Google as the copyright holder. Because Google (and most open source projects) do not require copyright assignemnt for contributions, each contributor maintains their copyright. Some large corporate contributors then tried to add their own name to the copyright line in the LICENSE file or in file headers. This quickly becomes unwieldy, and puts a tremendous burden on anyone building on top of Chromium, since the license requires that they keep all copyright lines intact. The compromise was to create an AUTHORS file that would list all of the copyright holders. The LICENSE file and source file headers would then include that list by reference, listing the copyright holder as "The Chromium Authors". This also become cumbersome to simply keep the file up to date with a high rate of new contributors. Plus it's not always obvious who the copyright holder is. Sometimes it is the individual making the contribution, but many times it may be their employer. There is no way for the proejct maintainer to know. Eventually, Google changed their policy to no longer recommend trying to keep the AUTHORS file up to date proactively, and instead to only add to it when requested: https://opensource.google/docs/releasing/authors. They are also clear that: > Adding contributors to the AUTHORS file is entirely within the > project's discretion and has no implications for copyright ownership. It was primarily added to appease a small number of large contributors that insisted that they be recognized as copyright holders (which was entirely their right to do). But it's not truly necessary, and not even the most accurate way of identifying contributors and/or copyright holders. In practice, we've never added anyone to our AUTHORS file. It only lists Tailscale, so it's not really serving any purpose. It also causes confusion because Tailscalars put the "Tailscale Inc & AUTHORS" header in other open source repos which don't actually have an AUTHORS file, so it's ambiguous what that means. Instead, we just acknowledge that the contributors to Tailscale (whoever they are) are copyright holders for their individual contributions. We also have the benefit of using the DCO (developercertificate.org) which provides some additional certification of their right to make the contribution. The source file changes were purely mechanical with: git ls-files | xargs sed -i -e 's/\(Tailscale Inc &\) AUTHORS/\1 contributors/g' Updates #cleanup Change-Id: Ia101a4a3005adb9118051b3416f5a64a4a45987d Signed-off-by: Will Norris <will@tailscale.com>
2026-01-22wgengine: send disco key via TSMP on first contact (#18215)Claus Lensbøl1-0/+9
When we have not yet communicated with a peer, send a TSMPDiscoAdvertisement to let the peer know of our disco key. This is in most cases redundant, but will allow us to set up direct connections when the client cannot access control.

2025-12-17net/netmon, wgengine/userspace: purge ChangeDelta.Major and address TODOs ↵Jonathan Nobels1-14/+31
(#17823) updates tailscale/corp#33891 Addresses several older the TODO's in netmon. This removes the Major flag precomputes the ChangeDelta state, rather than making consumers of ChangeDeltas sort that out themselves. We're also seeing a lot of ChangeDelta's being flagged as "Major" when they are not interesting, triggering rebinds in wgengine that are not needed. This cleans that up and adds a host of additional tests. The dependencies are cleaned, notably removing dependency on netmon itself for calculating what is interesting, and what is not. This includes letting individual platforms set a bespoke global "IsInterestingInterface" function. This is only used on Darwin. RebindRequired now roughly follows how "Major" was historically calculated but includes some additional checks for various uninteresting events such as changes in interface addresses that shouldn't trigger a rebind. This significantly reduces thrashing (by roughly half on Darwin clients which switching between nics). The individual values that we roll into RebindRequired are also exposed so that components consuming netmap.ChangeDelta can ask more targeted questions.

2025-10-06util/checkchange: stop using deephash everywhereBrad Fitzpatrick1-17/+39
Saves 45 KB from the min build, no longer pulling in deephash or util/hashx, both with unsafe code. It can actually be more efficient to not use deephash, as you don't have to walk all bytes of all fields recursively to answer that two things are not equal. Instead, you can just return false at the first difference you see. And then with views (as we use ~everywhere nowadays), the cloning the old value isn't expensive, as it's just a pointer under the hood.

2025-10-06feature/featuretags: add LazyWG modular featureBrad Fitzpatrick1-19/+33
Due to iOS memory limitations in 2020 (see https://tailscale.com/blog/go-linker, etc) and wireguard-go using multiple goroutines per peer, commit 16a9cfe2f4ce7d introduced some convoluted pathsways through Tailscale to look at packets before they're delivered to wireguard-go and lazily reconfigure wireguard on the fly before delivering a packet, only telling wireguard about peers that are active. We eventually want to remove that code and integrate wireguard-go's configuration with Tailscale's existing netmap tracking. To make it easier to find that code later, this makes it modular. It saves 12 KB (of disk) to turn it off (at the expense of lots of RAM), but that's not really the point. The point is rather making it obvious (via the new constants) where this code even is.

fixes tailscale/corp#27506 The source address link selection on sandboxed macOS doesn't deal with loopback addresses correctly. This adds an explicit check to ensure we return the loopback interface for loopback addresses instead of the default empty interface.

Linux (#13172) In 2f27319baf71681e221904d3a3ffe1badedc8e2e we disabled GRO due to a data race around concurrent calls to tstun.Wrapper.Write().
