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>
2025-10-06ipn/ipnlocal: fix another racy test (#17472)M. J. Fromberger1-2/+2
Some of the test cases access fields of the backend that are supposed to be locked while the test is running, which can trigger the race detector. I fixed a few of these in #17411, but I missed these two cases. Updates #15160 Updates #17192 Change-Id: I45664d5e34320ecdccd2844e0f8b228145aaf603 Signed-off-by: M. J.

2025-10-06appc,ipn/ipnlocal: receive AppConnector updates via the event bus (#17411)M. J. Fromberger1-43/+36
Add subscribers for AppConnector events Make the RouteAdvertiser interface optional We cannot yet remove it because the tests still depend on it to verify correctness. We will need to separately update the test fixtures to remove that dependency. Publish RouteInfo via the event bus, so we do not need a callback to do that. Replace it with a flag that indicates whether to treat the route info the connector has as "definitive" for filtering purposes. Update the tests to simplify the construction of AppConnector values now that a store callback is no longer required. Also fix a couple of pre-existing racy tests that were hidden by not being concurrent in the same way production is.

2025-10-02appc,*: publish events for route updates and storage (#17392)M. J. Fromberger1-3/+4
Add and wire up event publishers for these two event types in the AppConnector. Nothing currently subscribes to them, so this is harmless. Subscribers for these events will be added in a near-future commit. As part of this, move the appc.RouteInfo type to the types/appctype package. It does not contain any package-specific details from appc. Beside it, add appctype.RouteUpdate to carry route update event state, likewise not specific to appc. Update all usage of the appc.* types throughout to use appctype.* instead, and update depaware files to reflect these changes. Add a Close method to the AppConnector to make sure the client gets cleaned up when the connector is dropped (we re-create connectors). Update the unit tests in the appc package to also check the events published alongside calls to the RouteAdvertiser. For now the tests still rely on the RouteAdvertiser for correctness; this is OK for now as the two methods are always performed together. In the near future, we need to rework the tests so not require that, but that will require building some more test fixtures that we can handle separately.

[capver 89] First we had Capabilities []string. Then https://tailscale.com/blog/acl-grants (#4217) brought CapMap, a superset of Capabilities. Except we never really finished the transition inside the codebase to go all-in on CapMap. This does so. Notably, this coverts Capabilities on the wire early to CapMap internally so the code can only deal in CapMap, even against an old control server. In the process, this removes PeerChange.Capabilities support, which no known control plane sent anyway. They can and should use PeerChange.CapMap instead.

2023-11-17ipn/ipnlocal,cmd/tailscale: persist tailnet name in user profileMarwan Sulaiman1-1/+1
This PR starts to persist the NetMap tailnet name in SetPrefs so that tailscaled clients can use this value to disambiguate fast user switching from one tailnet to another that are under the same exact login. We will also try to backfill this information during backend starts and profile switches so that users don't have to re-authenticate their profile. The first client to use this new information is the CLI in 'tailscale switch -list' which now uses text/tabwriter to display the ID, Tailnet, and Account. Since account names are ambiguous, we allow the user to pass 'tailscale switch ID' to specify the exact tailnet they want to switch to.

2023-10-17taildrop: implement asynchronous file deletion (#9844)Joe Tsai1-7/+7
File resumption requires keeping partial files around for some time, but we must still eventually delete them if never resumed. Thus, we implement asynchronous file deletion, which could spawn a background goroutine to delete the files. We also use the same mechanism for deleting files on Windows, where a file can't be deleted if there is still an open file handle. We can enqueue those with the asynchronous file deleter as well.
