Kristoffer Dalby 83d8a29b62 api/v2: list token-made auth keys to a token without all=true 
Keys an OAuth token makes are marked so. No listing holds an invalid
key.
 2026-10-28 18:28:23 +00:00
Kristoffer Dalby 6c03637c8e api/v2: show userId on admin-made tagged keys 
An admin key's user is recorded as the creator of the tagged keys it
makes. A tagged key re-registers a machine by its tags, whoever made it.

Kristoffer Dalby e25d937c84 state: refresh the NodeStore copies of a user in UpdateUser 2026-10-28 18:28:23 +00:00
Kristoffer Dalby 5d7c1a7d14 state: write every user column in UpdateUser 2026-10-28 18:28:23 +00:00
Kristoffer Dalby 93e01c1aee state: announce a node online only after it was offline 
A stream back within the reconnect grace sent peers an online patch,
a router's sent every node a policy response, and a relogin on
unchanged keys sent a key patch; nothing had changed.
 2026-10-28 18:28:22 +00:00
Kristoffer Dalby dacdfd8aaa change: do not echo a node's own report back to it 
An endpoint or DERP report came back to the node as a self update;
SaaS sends it to the node's peers only.
 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 24e3a8d526 state, change: send a deleted node's removal only to its peers 
The removal went to every node, also those the policy hid the node from.
The delete now returns the node's peers from the snapshot it replaces.
 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 179af840da change: coalesce policy recomputes that carry an origin node 
The recompute render ignores the origin and always carries the node's
own entry, so a burst of tag writes cost every node one per write.
 2026-10-28 18:28:22 +00:00
Kristoffer Dalby b1c142d9c9 state: say a taken name is already taken 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 8f2ca0d01e db, state: keep the ephemeral flag a node was created with 
The flag moves from the key to the node, so a login with another key no
longer changes it. A user claiming a tagged node still clears it. v1
nodes carry the flag.

Kristoffer Dalby 999970edd4 state: cut a label so its -N suffix fits in 63 bytes 2026-10-28 18:28:22 +00:00
Kristoffer Dalby eeea38c627 state: treat extra DNS record names as taken node names 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 568f27bd84 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 18:28:22 +00:00
Kristoffer Dalby f60e4c3f7f 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.
 2026-10-28 18:28:22 +00:00
Kristoffer Dalby e785afd35a 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 18:28:22 +00:00
Kristoffer Dalby f7c630fdf9 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 18:28:22 +00:00
Kristoffer Dalby 9dfd78e42e 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 18:28:22 +00:00
Kristoffer Dalby 8fb3d320a5 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 18:28:22 +00:00
Kristoffer Dalby 98380c2be4 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 dde74266d9 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 18:28:22 +00:00
Kristoffer Dalby bebc563035 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.

Kristoffer Dalby d3b4e321f3 state: forget a node's SSH check approvals when it is expired 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 94b138e184 state: honour SSH check approvals only while the source keeps its owner 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 56af18051f 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 18:28:22 +00:00
Kristoffer Dalby fda03f277f state: serialise registrations presenting an unused single-use key 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 690d72b7ee 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 18:28:22 +00:00
Kristoffer Dalby c3702993ce state: undo a failed re-registration without reverting newer writes 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 26be57d2de state: write node rows from the NodeStore under persistMu 2026-10-28 18:28:22 +00:00
Kristoffer Dalby ab2a2bf4af state: apply map requests only under the node key that authorised them 2026-10-28 18:28:22 +00:00
Kristoffer Dalby 95c6129315 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.

Kristoffer Dalby 8191a88774 policy, state: log only the routes auto-approval adds 2026-10-28 18:28:22 +00:00
Kristoffer Dalby ff5d0307f9 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 18:28:22 +00:00
Kristoffer Dalby f2f03b91b4 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 18:28:22 +00:00
Kristoffer Dalby 3ce5bf5d9a 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 18:28:22 +00:00
Kristoffer Dalby 4d5b202db1 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 18:28:22 +00:00
Kristoffer Dalby 9b7cd07e54 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 18:28:21 +00:00
Kristoffer Dalby 819ae5e8ac 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 18:28:21 +00:00
Kristoffer Dalby c31c8187b1 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 18:28:21 +00:00
Kristoffer Dalby 4bd72f1b68 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.

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.

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.
