Kristoffer Dalby ab4596f40a state: invalidate SSH check approvals on owner changes and expiry 
Honor approval only while its source keeps the same owner and is live.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 343680c092 state: let a pre-auth key that is no longer valid only wake its node 
A login that keeps its node key leaves a live node's expiry alone, even
with a valid key, and a wake-up is not refused for the tags it requests.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 1449fa9f84 state: auto-approve routes in the NodeStore writer, not on reload 
Registration approval runs on the node the writer replaces. A policy
reload approves nothing, and a map request only when its announced
routes change, so neither re-grants a route an admin revoked.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 0e1140c710 policy: offer exit routes only to viewers whose rules reach the internet 
Every destination overlaps /0, so any rule offered a peer's exit routes.
They now need a rule to the internet, the test exit-node visibility
uses; via steering defers them to a regular grant only on that test.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby e0c9ff425e mapper: send a router all of its own routes 
Its AllowedIPs held only the primaries the policy let it reach. It now
holds every approved route, and PrimaryRoutes the ones it serves.

Fixes #3626
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby a49f9122f7 policy: reduce merged destination prefixes to the node's own addresses 
Adjacent node addresses merge into one prefix, and each node's filter
kept all of it. A prefix made only of node addresses now shrinks to the
node's own; a prefix the policy wrote, or one the node routes, stays.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 8c3b615bda api, policy/v2: refuse route prefixes with host bits 
Routes are matched as written, so such a prefix never equals the one a
client announces. The approval APIs answer 400 and autoApprovers refuses
it at load and write, with Tailscale's text.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 5fd173178f state, policy/v2: classify only effective route changes 
Compare announced-and-approved routes only when immutable route inputs
change. Publish Hostinfo without unnecessary peer adjacency rebuilds.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby edbb1fe9b6 policy/v2, state: elect primaries by oldest control session 
A router that reconnects joins as a standby; one that kept its session
takes its routes back once available again, as on Tailscale. Both the
global and the via election use it, in place of anti-flap stickiness.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby de8a0cc7eb state, policy/v2: elect available routers and retain unavailable routes 
Recompute via elections on health changes and check online state and expiry.
With no available router, retain the previous primary or lowest-ID approver;
exclude routers the prober marked unreachable.
 2026-11-02 17:46:52 +00:00
Kristoffer Dalby 1c94588bf9 state: keep HA health probes active without delaying unrelated routers 
Probe lone unhealthy advertisers. Defer results only for routers whose
routes tie them to a router still awaiting its probe.
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby 170ae26ad7 policy/v2: refuse check SSH rules with tag sources 
A check asks the source's user to log in again, and a tagged node has
none. Tailscale SaaS refuses the rule; headscale accepted it.
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby e3ecff567e policy/v2: bound grant destination expansion 
Require one port or range per grant IP entry. Reject more than 100,000
declared destination/port-range combinations on every parse.
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby fa6b46bfd9 policy/v2: need every dst node for a tests accept, no range sources 
An accept passes only when each node behind the dst is reached, as on
Tailscale SaaS; a deny keeps its rule. A CIDR, "*" or autogroup:tagged
src names no user or host, so its test fails.
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby e254fd798e policy/v2: validate SSH test sources and destinations like SaaS 
Reject address-range sources and autogroup:member destinations.
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby b56b6dcae1 policy/v2: map login 0 to no local user in SSH rules 
Every rule that maps root now carries "0": "", as Tailscale SaaS writes
it, also when the policy lists "0".
 2026-11-02 17:46:51 +00:00
Kristoffer Dalby 1b76d9071a policy/v2: keep via steering bounded across route and user changes 
Refresh clients when the last via grant disappears. Match each ACL once,
deduplicate routes, and elect once per route the peer actually serves.
 2026-11-02 17:46:50 +00:00
Kristoffer Dalby 363ba7be44 hscontrol, servertest: add key list scope golden data 
Read-only and key-making OAuth tokens of each tag set list auth keys
with and without all=true, over admin- and token-made keys of every tag
relation, one admin key made after the token-made ones.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby e8b44c653f servertest: add user role dispatch golden data 
An admin role change under autogroup:admin, mirrored as a user rename;
peers, filter and frames per node per step, and v2 device users.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 1318f2802f servertest, state: add node name golden data 
Labels under taken hostnames, case-only renames, hostname changes, long
hostnames and a Service's name; API, peer and self per step, and State
labels as a restart would load them.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby a34eb4f535 policy/v2, servertest: add policy generation golden data 
One policy over joins, a via router swap, an admin tag, a delete and a
group edit; filter, SSH, peers and routes per step, and the manager
against a fresh one.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 349c4db600 servertest: add hidden peer and route announcement golden data 
What a node hears of peers it cannot see, and what a router's peers hear
of routes it announces; presence, removals, peers and routes per step.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 20a1855147 servertest: count map frames per client 
Counts ControlTime events, so frames that leave the netmap as it was,
or that a delta client applies in place, still show.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby b4217925c9 servertest: recapture map delivery golden data 
The probe now bounds snapshot reads and keeps feature refusals as data.
SaaS now sends appc and sshd laptop's unchanged entry on the restore.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby d84c1927f9 servertest: wait for each replayed join before the next 
Polls start in the background, so a later router could come online
first and keep the global primary SaaS gave the first.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 75040798e4 servertest: count deleted nodes in replayed peer views 
Only nodes still in State resolved to an alias, so a client that kept
a deleted peer passed the peers and route owner checks.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby f4af5e0286 servertest: recapture via HA failover golden data 
The probe now bounds its reads and stops when a step loses data.
Route owners and peers match the first capture at every step.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby c979d82c50 hscontrol, servertest: fail on any unread pending login or expiry entry 
Each map serves one capture, so a misspelled capture name never went
stale.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby e4752f06c5 servertest: require a map on each stream an expiry replay opens 
The cached netmap outlives a stream, so a refused re-poll passed.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 99af4aa8a5 servertest: compare filter and SSH rules in expiry replays 
Changed-or-not alone let empty rules pass for SaaS's new ones.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 44c6810b10 servertest: recapture ephemeral, expiry and pending login golden data 
The expiry file now holds the shared policy, DNS and observer setup.
Outcomes match the first capture; collection was seen one poll earlier.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 1d48f67534 servertest: judge ephemeral collection apart from the poll that saw it 
Killed nodes are checked once at the last read, for devices left and
whether the observer lost them since the kill.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby bd5ae1e0fb servertest: recapture v2 OAuth and policy API golden data 
Tag writes are read back once the tags hold, and both files carry a
baseline snapshot. Statuses and read-backs match the first capture.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby a21d725853 servertest, policy/v2: replay tag owner chain joins through registration 
A key login never asks the policy about requested tags, so the joins are
checked where headscale decides them. OAuth mints stay at
TagOwnedByTags.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 8e3270b180 servertest: recapture re-authentication golden data 
The probe now stops a refused login's retries; the replay disconnects
there too. Outcomes match the first capture, and user IDs are labels.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 70eb9366be servertest: fail on skip entries no lifecycle replay reads 
Consumers check entries under their own capture only, so a bare or
misspelled key never went stale.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby cb3a5446f7 servertest: check route continuity in every streamed step 
Removal and route drops were judged only on steps SaaS sent frames for;
silent steps and a clear-then-restore within a step went unchecked.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 4c7d88c08e servertest: fail step checks that never hold 
A match on the last sample before the deadline no longer passes.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 95f6116a87 servertest: keep the address family in filter comparisons 
A rule missing one family of a peer's addresses compared equal.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 6bbf6b7b94 servertest: check peer visibility, routes and addresses apart 
A listed difference in one no longer hides the others; the exit route
entries now key the AllowedIPs check alone.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 4cbee05d67 servertest: check peers and filters apart after a via source loss 
The user node's filter already matches SaaS and is now asserted.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 63130fb8e5 policy/v2: add grant port list refusal capture 
Grant and ACL refusals share one check-keyed refused/message check.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 46b84d47fe servertest, state: add map delivery golden data 
A retag through the API, a running peer's DERP, disco, hostname and
port, down and up gaps around policy pushes; peers, filters and frames
per node.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby ea474ee06c servertest: add via HA failover golden data 
One route on a non-via router and a via pair through crashes and
returns, the via group down, expiry, approval loss, withdraw,
re-advertise and delete; route owner and peers per viewer per step.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby b15b15fdd3 servertest: join replayed routers with their routes 
A route update sent after the join could be overtaken by the stream's
first request and dropped; the probe joined with the routes set.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby c9dbfb1bef servertest, hscontrol: add ephemeral, expiry, pending login golden data 
Ephemeral devices through logout, deletes, re-auth and collection;
expired routers and nodes, a client's own expiry and logout; a login
waiting across restarts, replayed exchange by exchange.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby ee82df334e servertest: add login flag, endpoint, disco rotation and expiry helpers 
WithLoginFlags and WithEndpoints shape what a client sends; RotateDisco
logs in again on a new disco key and leaves an auth URL waiting;
SetExpirySooner asks for an earlier key expiry.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby ca9874617b hscontrol, servertest: add v2 OAuth and policy API golden data 
OAuth clients, tokens, keys and tag writes by principal, and policy
writes over a baseline, replayed through v1 and v2; a deleted parent
client's key joins real clients.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby aa4721b3be policy/v2, servertest: add via port captures 
A port-limited ACL entry beside a via grant, and a via tag with no
advertiser. Via HA replays now compare router filters by address.
 2026-11-02 16:09:00 +01:00
Kristoffer Dalby 1449dc8c4f policy/v2, servertest: add multi-route router captures 
A seven-route router and an exit node under six policies; replayed
through policy, peer map and map stream. Peer map now checked against
SaaS peers.
