Kristoffer Dalby e6c41753a3 mapper: send nothing while any stream awaits its initial map 
Sent to the ready streams alone, a change counted as delivered and
never reached the new stream; the worker retries it once the map is out.
 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 36a42548a0 mapper: cap concurrent map sessions per node 
A node chose how many map streams it held, each pinning a session.
The fifth replaces the oldest; same shape as #3468's mapper commit.

Kristoffer Dalby ed40c31c87 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.

Kristoffer Dalby 6a5ea877f4 state: say a taken name is already taken 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 37655ae586 db: succeed on a repeated revoke of an auth key 
A repeated v2 DELETE of an auth key now answers 200, as Tailscale does.

Kristoffer Dalby 9ad6fd24b2 auth: answer a logout that deletes an ephemeral node as authorised 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 3dfea48020 cli: show a node's own ephemeral flag instead of its key's 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 5ce9c82ffa gen/client/v1: regenerate for the node ephemeral flag 2026-10-28 16:35:22 +00:00
Kristoffer Dalby d6a657aaeb 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 16:35:22 +00:00
Kristoffer Dalby 799a301c2d db, types: add a nodes column for the ephemeral flag 
The migration fills it from the key each node references.

Kristoffer Dalby 2d3de03f1d db: remove unused RenameNode 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 47507b2c9a state: bump duplicate node names loaded from the database 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 15b628f8dc state: cut a label so its -N suffix fits in 63 bytes 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 5e50859d58 state: treat extra DNS record names as taken node names 2026-10-28 16:35:22 +00:00
Kristoffer Dalby e69970b5e2 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 16:35:22 +00:00
Kristoffer Dalby f26853dc7f db, api/v1: revoke rather than delete an ephemeral pre-auth key in use 
The v1 list now hides revoked keys, so keys revoked through v2 also drop
out of `headscale preauthkeys list`.
 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 044b6b61fb hscontrol: arm the ephemeral GC at pre-auth key registration 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 43af1db6a0 hscontrol: skip garbage collecting a node that is no longer ephemeral 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 8eb706fb78 db: wrap the sequential IP allocator so freed addresses are reused 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 14a3749f78 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 16:35:22 +00:00
Kristoffer Dalby 6cab9ac7f7 noise: stop serving metrics inside the tunnel 
Any machine key reached it, bypassing metrics_listen_addr. No client
asks for it.
 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 9db5e423e5 hscontrol: bound client-chosen text in request logs 
Clip at the sinks: handler errors, the request line, SSH local_user.
 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 089a0ed13e 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 16:35:22 +00:00
Kristoffer Dalby 0ab509ee7b 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 16:35:22 +00:00
Kristoffer Dalby dabfb3c7b4 mapper: keep an expired node authorised in its own entry 
Tailscale SaaS sends an expired node MachineAuthorized and no Expired
flag; its past KeyExpiry already moves the client to NeedsLogin.
 2026-10-28 16:35:22 +00:00
Kristoffer Dalby 71556e5a30 .github: regenerate integration test workflow 2026-10-28 16:35:22 +00:00
Kristoffer Dalby d1da9982f4 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 16:35:22 +00:00
Kristoffer Dalby 9cfd05fe5a 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 16:35:22 +00:00
Kristoffer Dalby 8ebc2f41bf 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 16:35:22 +00:00
Kristoffer Dalby bd12059446 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 16:35:22 +00:00
Kristoffer Dalby 437a607ef3 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 16:35:22 +00:00
Kristoffer Dalby 033e3de65c 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 16:35:22 +00:00
Kristoffer Dalby 8e4159a336 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 16:35:22 +00:00
Kristoffer Dalby 549a09b4e5 state: forget a node's SSH check approvals when it is expired 2026-10-28 16:35:22 +00:00
Kristoffer Dalby eb426183d2 state: honour SSH check approvals only while the source keeps its owner 2026-10-28 16:35:22 +00:00
Kristoffer Dalby aa8bb46b4e 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 16:35:22 +00:00
Kristoffer Dalby 62c63ff62b state: serialise registrations presenting an unused single-use key 2026-10-28 16:35:21 +00:00
Kristoffer Dalby f52d2216a6 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 16:35:21 +00:00
Kristoffer Dalby 12acbb2ffb state: undo a failed re-registration without reverting newer writes 2026-10-28 16:35:21 +00:00
Kristoffer Dalby c2a4183c03 state: write node rows from the NodeStore under persistMu 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 96d68fcbc4 state: apply map requests only under the node key that authorised them 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 4c98552b2d 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 16:35:21 +00:00
Kristoffer Dalby aca11eae02 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.
 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 87de37fc7a 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.
 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 12fb9fae43 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.
 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 1c8d768a21 policy, state: log only the routes auto-approval adds 2026-10-28 16:35:21 +00:00
Kristoffer Dalby cb10a23c61 poll: hold the map session's node as a view 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 7112fcd990 policy/matcher, types: compare a node's routes to matchers as ranges 2026-10-28 16:35:21 +00:00
Kristoffer Dalby cb2097ad65 policy/matcher: binary-search ranges in overlap checks 2026-10-28 16:35:21 +00:00
Kristoffer Dalby 43e8802afc policy: look up approved routes in a set when auto-approving 
Avoid scanning the growing approval list for every announcement.
Use the sorted current routes when identifying additions.
