The interstitial was the body of /oidc/callback, the URL carrying the
single-use code, so any reload re-entered the spent exchange. Redirect to
GET /register/confirm/{auth_id}, also missing from the route table.
Covers every change shape under four policy shapes, plus connect churn. The
zero-matcher shape is the gap: buildTailPeers skips ReduceNodes there, so the
peer lookup is the only self filter left.
ListPeers with explicit IDs filtered every node, not every peer, so a change
batch naming the recipient returned it as its own peer. db.ListPeers keeps
this out with `id <> nodeID`; the NodeStore rewrite dropped it.
A bare 404 is indistinguishable from any other map-path error to a Tailscale
client: it retries forever, still logged in. Only a self node with a past
KeyExpiry reaches NeedsLogin. Also skip the reconnect grace wait, which a
deleted node can never satisfy.
Fixes#3410
It fills PeersRemoved without deleting anything. The batcher now tears down
the session behind every removed id, so a caller would kill a live poll.
Updates #3410
Dropping the batcher entry left serveLongPoll streaming to a node that no
longer exists: Close ranges b.nodes and can no longer reach it, so shutdown
blocks and the client keeps polling instead of re-authenticating.
Updates #3410
DNS names are case-insensitive, but clients match extra records against
the lowercased query name, so records with mixed-case names (for example
"Printer.fritz.box" in an extra_records_path file) never resolved and
queries fell through to the global nameserver.
Normalize record names to lowercase where the records enter the tailcfg
DNS config, covering both dns.extra_records and extra_records_path.
Fixes#2782
After Remove/Rename, the extra-records filewatcher retried with
context.Background and the default 15-minute backoff budget, so Close
could not stop Run. Cancel that retry when closeCh closes. If the file
is still missing after the budget, watch the parent directory so a later
recreate is seen.
Close the fsnotify watcher on NewExtraRecordsManager error paths after
NewWatcher succeeds.

Serve stored a Background context for tailsql and called
context.Done() during signal shutdown. Done only returns the
done channel and does not cancel, so tailsql never stopped
when Headscale shut down.
Create a cancellable child of the Serve context, run
`runTailSQLService` in the listener errgroup so its error is
surfaced, and call the cancel func on shutdown - tailsql
unblocks on ctx.Done.
The instructions are duplicated between the docs and the HTML page
headscale serves at /apple. Reorder the tvOS steps there to match, so
the VPN configuration is installed before the alternate coordination
server URL is set.
Fix the inverted HTTP metrics skip condition, which caused the collector to ignore all requests except OPTIONS.
Apply the correction to both the main and Noise routers so regular HTTP traffic is included in http_requests_total and http_request_duration_seconds.
PR tailscale/tailscale#20646 changed the representation of DERP region
IDs from plain ints to a tailcfg.DERPRegionID type. This patch
requires that version of the tailscale.com library and updates our
code to also use the new type.
Updates: tailscale/tailscale#20165
(cherry picked from commit 79695ab51b)
Go 1.27 allows setting promoted fields of embedded structs directly in
composite literals, so gorm.Model wrappers go away. Plus strings.Cut,
errors.AsType, reflect.TypeAssert and one gofumpt nit.
waitForFollowup selected on ctx.Done() and the verdict channel with equal
priority; when both were ready, select picked at random and discarded a
successful registration as a spurious 401 timeout. Check for a completed
verdict first, race the deadline only if none is ready.
Fixes#3385
With node.ephemeral.inactivity_timeout set, ephemeral nodes are
usually deleted after they go offline, but under reconnect churn some
departed nodes stayed in the node list as disconnected indefinitely
until removed manually or until Headscale restarted.
Ephemeral cleanup is timer-based via EphemeralGarbageCollector, not a
periodic LastSeen scan. serveLongPoll cancelled any pending GC timer
at the very start of a long-poll attempt and only rescheduled on a
clean disconnect after Connect. If a reconnect cancelled the timer and
then failed before Connect (for example an UpdateNodeFromMapRequest
error), the deferred cleanup saw connectGen == 0 and returned without
Schedule. The node remained offline with no deletion timer and no
reconciler to recover it.
Cancel the ephemeral GC timer only after a successful Connect, so a
failed reconnect leaves an already-armed inactivity timer intact.
Successful reconnects still cancel GC once the node is online, and a
later disconnect reschedules as before.
Add TestFailedReconnectDoesNotCancelEphemeralGC to lock in the
ordering, plus IsScheduled and DeleteNodeFromStoreForTest helpers for
the test.

Re-registering a tagged node with a different key discarded the new key's
tags and left a stale auth-key reference; retag on key change and persist it.
Fixes#3370
/key handed out the Noise public key for any v>=39, a floor unrelated
to the handshake's capver.MinSupportedCapabilityVersion. Reject below
the supported floor, matching /ts2021, and drop the stale constant.
Fixes#3380
waitForFollowup returns nodeToRegisterResponse for a completed
registration without checking that the Noise session polling for the
result was started with the machine key that opened the registration.
That response carries the registering user's User and Login, so the auth
ID in the followup URL is the only thing protecting it.
handleRegister and handleLogout both call machineKeyMismatch before
handing back a node, so this is the one path of the three that does not.
The key is already available: HandleNodeFromAuthPath resolves the node
from the MachineKey cached in RegistrationData, so on the normal path the
node and the session agree and the check is a no-op.
The auth ID is 96 bits of randomness and is not guessable, so this is not
reachable by brute force. It is logged at info level when a registration
is created, which makes log access the realistic way to obtain one.
The existing followup_registration_success case built its node with
CreateNodeForTest, which picks a random machine key that no real
registration would produce. Set the registering machine key so the
fixture matches the production path.

The chi migration dropped GET; JS/WASM control clients open /ts2021 as a WebSocket GET and were rejected with 405 before reaching NoiseUpgradeHandler.
Fixes#3357
Scan a node-health check registry at boot and log each node whose name
can't form a valid FQDN, with the rename fix. Log-only, no mutation.
