2026-04-20types/netmap,client/local: modify services format in local apiAdriano Sela Aviles1-4/+3
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.

2026-04-17client/local,types/netmap: modify services format in local apiAdriano Sela Aviles1-3/+4
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 <adriano@tailscale.com>

2026-04-05client/web: fix nil metricCapture crash in mockLocalAPIBrad Fitzpatrick1-1/+3
The upload-client-metrics handler called metricCapture without checking if it was nil or if the metrics slice was empty. Most tests pass nil for metricCapture, so if a metrics upload races in during the test, it panics.

2026-04-05cmd/vet: add subtestnames analyzer; fix all existing violationsBrad Fitzpatrick3-29/+29
Add a new vet analyzer that checks t.Run subtest names don't contain characters requiring quoting when re-running via "go test -run". This enforces the style guide rule: don't use spaces or punctuation in subtest names. The analyzer flags: - Direct t.Run calls with string literal names containing spaces, regex metacharacters, quotes, or other problematic characters - Table-driven t.Run(tt.name, ...) calls where tt ranges over a slice/map literal with bad name field values Also fix all 978 existing violations across 81 test files, replacing spaces with hyphens and shortening long sentence-like names to concise hyphenated forms.

2026-04-01tka: refer consistently to "DisablementValues"Alex Chan1-2/+0
This avoids putting "DisablementSecrets" in the JSON output from `tailscale lock log`, which is potentially scary to somebody who doesn't understand the distinction. AUMs are stored and transmitted in CBOR-encoded format, which uses an integer rather than a string key, so this doesn't break already-created TKAs.

2026-03-11client/web: signal need to wait for auth across tabsGesa Stupperich5-71/+99
This amends the session creation and auth status querying logic of the device UI backend. On creation of new browser sessions we now store a PendingAuth flag as part of the session that indicates a pending auth process that needs to be awaited. On auth status queries, the server initiates a polling for the auth result if it finds this flag to be true. Once the polling is completes, the flag is set to false. Why this change was necessary: with regular browser settings, the device UI frontend opens the control auth URL in a new tab and starts polling for the results of the auth flow in the current tab. With certain browser settings (that we still want to support), however, the auth URL opens in the same tab, thus aborting the subsequent call to auth/session/wait that initiates the polling, and preventing successful registration of the auth results in the session status. The new logic ensures the polling happens on the next call to /api/auth in these kinds of scenarios. In addition to ensuring the auth wait happens, we now also revalidate the auth state whenever an open tab regains focus, so that auth changes effected in one tab propagate to other tabs without the need to refresh. This improves the experience for all users of the web client when they've got multiple tabs open, regardless of their browser settings.

2026-03-04cmd/tailscale,ipn,net/netutil: remove rp_filter strict mode warnings (#18863)Mike O'Driscoll1-19/+0
PR #18860 adds firewall rules in the mangle table to save outbound packet marks to conntrack and restore them on reply packets before the routing decision. When reply packets have their marks restored, the kernel uses the correct routing table (based on the mark) and the packets pass the rp_filter check. This makes the risk check and reverse path filtering warnings unnecessary. Updates #3310 Fixes tailscale/corp#37846 Signed-off-by: Mike O'Driscoll <mikeo@tailscale.com>

2026-01-23all: remove AUTHORS file and references to itWill Norris72-73/+73
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>

2025-10-02appc,*: publish events for route updates and storage (#17392)M. J. Fromberger1-4/+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.

2025-09-25various: allow tailscaled shutdown via LocalAPINick Khyl1-0/+6
A customer wants to allow their employees to restart tailscaled at will, when access rights and MDM policy allow it, as a way to fully reset client state and re-create the tunnel in case of connectivity issues. On Windows, the main tailscaled process runs as a child of a service process. The service restarts the child when it exits (or crashes) until the service itself is stopped. Regular (non-admin) users can't stop the service, and allowing them to do so isn't ideal, especially in managed or multi-user environments. In this PR, we add a LocalAPI endpoint that instructs ipnserver.Server, and by extension the tailscaled process, to shut down. The service then restarts the child tailscaled. Shutting down tailscaled requires LocalAPI write access and an enabled policy setting. Updates tailscale/corp#32674 Updates tailscale/corp#32675 Signed-off-by: Nick Khyl <nickk@tailscale.com>
