Kristoffer Dalby b26cc46b5b 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.
 2026-10-28 19:06:06 +00:00
Kristoffer Dalby 17415a84cc policy/v2: match no one for an ambiguous user outside policy writes 
A change to user identifiers must not block startup or later logins.
Keep policy writes strict; log ambiguous references on load and refresh.

Kristoffer Dalby c32865f5cb state: refresh the NodeStore copies of a user in UpdateUser 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 2ae1260f39 state: write every user column in UpdateUser 2026-10-28 19:06:05 +00:00
Kristoffer Dalby a8040b1c7d 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 19:06:05 +00:00
Kristoffer Dalby 5c0b617bc7 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 19:06:05 +00:00
Kristoffer Dalby e56de5ca9e 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 19:06:05 +00:00
Kristoffer Dalby 1525e7357a 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 19:06:05 +00:00
Kristoffer Dalby dfa06e1aac state: say a taken name is already taken 2026-10-28 19:06:05 +00:00
Kristoffer Dalby c0f974ad7a 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.
 2026-10-28 19:06:05 +00:00
Kristoffer Dalby f00b4f3bd6 db, types: add a nodes column for the ephemeral flag 
The migration fills it from the key each node references.
 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 58ea96d9ff state: bump duplicate node names loaded from the database 2026-10-28 19:06:05 +00:00
Kristoffer Dalby b952522dc2 state: cut a label so its -N suffix fits in 63 bytes 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 09380277ac state: treat extra DNS record names as taken node names 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 40902d57be 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 19:06:05 +00:00
Kristoffer Dalby ef142db36b 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 19:06:05 +00:00
Kristoffer Dalby be2f5333f4 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 19:06:05 +00:00
Kristoffer Dalby 6153b4fde3 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 19:06:05 +00:00
Kristoffer Dalby 4e77265b3c 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 19:06:05 +00:00
Kristoffer Dalby 27d693665c 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 19:06:05 +00:00
Kristoffer Dalby fd0fc9077c 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 19:06:05 +00:00
Kristoffer Dalby 0d725e494b 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 19:06:05 +00:00
Kristoffer Dalby 719d8a90fa 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.
 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 292005b6d4 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 19:06:05 +00:00
Kristoffer Dalby d96873434d 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 19:06:05 +00:00
Kristoffer Dalby f0bb724ee5 state: forget a node's SSH check approvals when it is expired 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 20886d61c5 state: honour SSH check approvals only while the source keeps its owner 2026-10-28 19:06:05 +00:00
Kristoffer Dalby a36c33e8e7 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 19:06:05 +00:00
Kristoffer Dalby 809035d7a6 state: serialise registrations presenting an unused single-use key 2026-10-28 19:06:05 +00:00
Kristoffer Dalby b4066260f0 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 19:06:05 +00:00
Kristoffer Dalby 974bfb0a96 state: undo a failed re-registration without reverting newer writes 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 6cb7d520ef state: write node rows from the NodeStore under persistMu 2026-10-28 19:06:05 +00:00
Kristoffer Dalby ef577487b2 state: apply map requests only under the node key that authorised them 2026-10-28 19:06:05 +00:00
Kristoffer Dalby d3cc4ad861 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 19:06:05 +00:00
Kristoffer Dalby b26dd72046 policy, state: log only the routes auto-approval adds 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 0eea9cadf4 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 19:06:05 +00:00
Kristoffer Dalby 7240ad2029 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 19:06:05 +00:00
Kristoffer Dalby 043ba98701 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 19:06:05 +00:00
Kristoffer Dalby df86073f54 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 19:06:05 +00:00
Kristoffer Dalby 5329b35d45 types: add when a node's run of control sessions began 2026-10-28 19:06:05 +00:00
Kristoffer Dalby fc395ba756 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 19:06:05 +00:00
Kristoffer Dalby bc131da3d6 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 19:06:05 +00:00
Kristoffer Dalby fb54b5e89b state: withhold HA probe results only for routers tied to a deferred one 2026-10-28 19:06:04 +00:00
Kristoffer Dalby 5892e2b1a6 state: keep probing a lone advertiser while it is unhealthy 2026-10-28 19:06:04 +00:00
Kristoffer Dalby 9b46f8f1fc 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 19:06:04 +00:00
Kristoffer Dalby a9024e564d 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 19:06:04 +00:00
Kristoffer Dalby 837ede3fbc 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 19:06:04 +00:00
Kristoffer Dalby 1b724a5bb9 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 19:06:04 +00:00
Kristoffer Dalby 18cbaf6f2a 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 19:06:03 +00:00
Kristoffer Dalby 483489942c 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.
