types/netmap,client/local: modify services format in local api

2026-04-20T16:22:23Z

Reverting back to the previous format (including the "svc:" prefix in the map's keys). Note that the /services endpoint in localapi, along with any software that relies on this is unreleased so this does not break any clients. Updates tailscale/corp#40052 Signed-off-by: Adriano Sela Aviles

client/local,types/netmap: modify services format in local api

2026-04-17T21:14:03Z

Updates the format of the service map that is served over the local api to be keyed without the "svc:" prefix. This change is backwards incompatible, this is OK because there is only one tailnet with the services-in-nodecapmap feature flag enabled, and the client side changes that start showing services over local api have not been released. (These were added in 4fcce6000d3d3f79d1ac1fca571a50efb059cbf2). Updates tailscale/corp#40052 Signed-off-by: Adriano Sela Aviles

all: use Go 1.26 things, run most gofix modernizers

2026-03-06T21:32:03Z

I omitted a lot of the min/max modernizers because they didn't result in more clear code. Some of it's older "for x := range 123". Also: errors.AsType, any, fmt.Appendf, etc. Updates #18682 Change-Id: I83a451577f33877f962766a5b65ce86f7696471c Signed-off-by: Brad Fitzpatrick

ipn/ipnlocal/netmapcache: add a package to split and cache network maps (#18497)

2026-01-26T22:55:30Z

This commit is based on part of #17925, reworked as a separate package. Add a package that can store and load netmap.NetworkMap values in persistent storage, using a basic columnar representation. This commit includes a default storage interface based on plain files, but the interface can be implemented with more structured storage if we want to later. The tests are set up to require that all the fields of the NetworkMap are handled, except those explicitly designated as not-cached, and check that a fully-populated value can round-trip correctly through the cache. Adding or removing fields, either in the NetworkMap or in the cached representation, will trigger either build failures (e.g., for type mismatch) or test failures (e.g., for representation changes or missing fields). This isn't quite as nice as automatically updating the representation, which I also prototyped, but is much simpler to maintain and less code. This commit does not yet hook up the cache to the backend, that will be a subsequent change. Updates #12639 Change-Id: Icb48639e1d61f2aec59904ecd172c73e05ba7bf9 Signed-off-by: M. J. Fromberger

all: remove AUTHORS file and references to it

2026-01-23T23:49:45Z

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
