Kristoffer Dalby 267ab2f4db state: treat extra DNS record names as taken node names 2026-10-28 14:42:22 +00:00
Kristoffer Dalby f271fc482d state: save the name NodeStore picks for a new node 
The row is committed before the name UPDATE, so a failed UPDATE still
returns the node and registration arms ephemeral cleanup.
 2026-10-28 14:42:22 +00:00
Kristoffer Dalby 9199cc8a06 state: test that a persist racing a delete cannot resurrect the node 
DeleteNode's early persistMu unlock is safe only while node persists
stay UPDATE-only; say so where the lock is declared.

Kristoffer Dalby f320fe10e8 mapper: show an expired peer online, without endpoints or DERP 
A connected expired node shows online to its peers. Neither its map
entry nor endpoint, DERP or disco patches carry the paths to reach it.
 2026-10-28 14:42:05 +00:00
Kristoffer Dalby 3a9a1a6a4c mapper: trim the Hostinfo sent to peers and to the node itself 
As on Tailscale SaaS, the node's own entry keeps Hostname, RequestTags,
RoutableIPs and Services; peers get Hostname, OS, Services without
peerapi-dns-proxy, SSH host keys and AppConnector, and resend on those.
 2026-10-28 14:42:05 +00:00
Kristoffer Dalby 15732cc071 state: apply requested tags on a key login that owns them 
A requested tag the key's user owns directly, or the key's tags own one
hop away, replaces the key's tags instead of refusing the login.
 2026-10-28 14:42:03 +00:00
Kristoffer Dalby 2a96a02d7b state: auto-approve routes after an admin tag change 
The new tags may approve announced routes. Approval runs once the policy
manager knows the new owner, as after a registration.
 2026-10-28 14:42:03 +00:00
Kristoffer Dalby e481fe49d3 state: drop auto-approved routes when they are withdrawn 
Only routes auto-approval alone granted go; approvals from before the
upgrade stay, as do routes an admin set.
 2026-10-28 14:42:02 +00:00
Kristoffer Dalby 070fe4c9bd db, types: add a column for auto-approved routes 
It starts empty: the current policy cannot tell which earlier approvals
were automatic, so all of them stay as an admin's.
 2026-10-28 14:42:02 +00:00
Kristoffer Dalby 3c0f6e8120 state: auto-approve on registration only when the node key rotates 
Registration runs the approval itself, once the policy manager knows the
node's owner, for a new node key or a change to the announced routes.

Kristoffer Dalby 822c8779a5 auth: store a client's earlier expiry and expire a tagged node at logout 
A client may bring its expiry forward, which turns expiry on for a node
without one, but still cannot push it back. Logout expires tagged nodes
too.
 2026-10-28 14:42:00 +00:00
Kristoffer Dalby 309cfbb342 auth, state: answer an expired node's same-key login with NodeKeyExpired 
The client then rotates its node key and logs in again, so no key is
judged under the expired one. The machine stays authorised.
 2026-10-28 14:41:47 +00:00
Kristoffer Dalby 7625a5ec90 state: forget a node's SSH check approvals when it is expired 2026-10-28 14:41:46 +00:00
Kristoffer Dalby e43ee22b01 state: honour SSH check approvals only while the source keeps its owner 2026-10-28 14:41:02 +00:00
Kristoffer Dalby bf1ff1665b 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.
 2026-10-28 14:40:49 +00:00
Kristoffer Dalby c1e4c56848 state: serialise registrations presenting an unused single-use key 2026-10-28 14:40:32 +00:00
Kristoffer Dalby a0893b43ff 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.
 2026-10-28 14:39:41 +00:00
Kristoffer Dalby 69c69d35e2 state: undo a failed re-registration without reverting newer writes 2026-10-28 14:39:40 +00:00
Kristoffer Dalby cff67806cb state: write node rows from the NodeStore under persistMu 2026-10-28 14:39:25 +00:00
Kristoffer Dalby 3cf284917d state: apply map requests only under the node key that authorised them 2026-10-28 14:38:12 +00:00
Kristoffer Dalby b36f9d443f 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.
 2026-10-28 14:38:11 +00:00
Kristoffer Dalby d648cf6b95 policy, state: log only the routes auto-approval adds 2026-10-28 14:38:08 +00:00
Kristoffer Dalby 619b731c18 types, state: reduce a node's routes against the matchers once 
Reuse matcher membership and approved subnets across the route list.
Preserve route order and HA co-router visibility.
 2026-10-28 14:38:03 +00:00
Kristoffer Dalby 235e6b62c7 state: skip route comparison for writes that leave routes alone 
Reuse immutable route inputs when classifying NodeStore writes.
Only derive routes when an announcement or approval changes.
 2026-10-28 14:37:37 +00:00
Kristoffer Dalby 04cbb8549d state, policy/v2: stop treating announced-only routes as policy changes 
Policy evaluation reads only announced-and-approved routes.
Keep publishing Hostinfo updates without rebuilding peer adjacency.
 2026-10-28 14:37:30 +00:00
Kristoffer Dalby 6b99ca0ad1 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.
 2026-10-28 14:37:29 +00:00

Kristoffer Dalby 97d4310caa state: keep a prefix mapped when no router is available 
Peers keep the routes of an offline or expired router, as on Tailscale.
The previous primary keeps the prefix, else the lowest-ID approver;
never one the prober declared unreachable.
 2026-10-28 14:37:27 +00:00
Kristoffer Dalby 111ed512fb policy/v2, state: elect via primaries among online, healthy routers 
Availability tests expiry itself, not only the online flag.
A health change on a via target now triggers a peer recompute.
 2026-10-28 14:37:26 +00:00
Kristoffer Dalby 67b88fe3b2 state: withhold HA probe results only for routers tied to a deferred one 2026-10-28 14:37:25 +00:00
Kristoffer Dalby 95b44713c1 state: keep probing a lone advertiser while it is unhealthy 2026-10-28 14:37:24 +00:00
Kristoffer Dalby 524ccc46aa db: keep only the current policy 
Every write inserted a row and nothing deleted one, while every reader
takes only the newest. Writers store and install under one lock, so an
uncommitted insert cannot outlive the newer row that pruned the rest.
 2026-10-28 14:37:08 +00:00
Kristoffer Dalby 6c06fcc919 state: install a written policy only after it is stored 
Writers validated by installing the policy live, so a store failure
left a refused or unstored policy enforced. Validate on a throwaway
manager, store, then reload from the stored row.
 2026-10-28 14:37:07 +00:00
Kristoffer Dalby 89b37fde7d policy/v2: refuse an empty policy 
SetPolicy returned a nil error for empty input it ignored, so the v1
API stored it as valid. Reload skips only the nil "no policy" case.
 2026-10-28 14:37:06 +00:00
Kristoffer Dalby 38613d7217 state: serialise policy reloads 
Load and install the stored policy as one step, so an older
reload cannot install its document over a newer one.
 2026-10-28 14:36:57 +00:00
Kristoffer Dalby b4e2c0e93f 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.
 2026-10-28 14:31:40 +00:00
Kristoffer Dalby 9f87fbd4f3 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.

 2026-10-28 14:25:41 +00:00
Kristoffer Dalby 8126f8727a state: drop registration locks once unused 
The lock is taken before any credential check, so client-chosen machine
keys grew the map forever. Ref-count entries; delete at zero.

Kristoffer Dalby 3c277949c7 auth, state: keep announced routes out of pending registrations 
Routes are the one long list; the first MapRequest reports them.
A relogin keeps the node's own routes until then.

Kristoffer Dalby 7259ef6edd hscontrol: refuse a key expiry that cannot be encoded 
handleRegister, the OIDC auth path and SetNodeExpiry refuse it. Expiries
are stored in UTC, which SQLite can read back, and loaded in UTC, as
PostgreSQL returns the server's zone. The v1 API answers 400.

 2026-10-28 14:25:41 +00:00
Kristoffer Dalby 159deeec41 mapper: skip peers whose key expiry cannot be encoded 
json.Marshal refuses a year outside [0,9999], so one stored expiry
failed every map with that node. TailNode and key patches send UTC, the
builder drops what fails and the boot scan names the node.

Kristoffer Dalby eeb0ef0901 state: give another user's key on a tagged machine a new device 
Only a key that speaks for a tagged node re-authenticates it: a tagged
key, or one of the user it was tagged from. Another user's key or login
adds that user's own device, or only wakes the node under its node key.

 2026-10-28 14:22:20 +00:00
Kristoffer Dalby abbec204a2 state: never serve a single address inside the node ranges 
Such a route names a node, not a subnet: it stays approved and listed
but no viewer gets it. Via inclusions skip the election, so the rule
sits on everything RoutesForPeer returns.

Kristoffer Dalby cd62031b98 state: stop the auth cache TTL sweeper on Close 
The expirable LRU ran its sweeper forever, one goroutine per State. Purge
first so pending waiters get ErrRegistrationExpired instead of hanging.
The OIDC state cache is closed at server shutdown for the same reason.

Kristoffer Dalby 51b420865e state: own request memory before storing nodes 
A reused RegisterRequest.Hostinfo was written and stored while NodeStore readers cloned it.

Kristoffer Dalby 552356a2ee state: skip the caller's policy refresh once the writer applied it 
The writer refreshes the policy manager before publishing its batch, so
the caller's SetNodes with the published snapshot recompiled it back.

Kristoffer Dalby 5d21186f22 state: release persistMu before the NodeStore delete 
Holding it serialised concurrent deletes into one NodeStore batch and
