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.

Kristoffer Dalby baf93d8b2c mapper: stop an older initial map removing peers newer streams hold 
AddNode diffed its map against tracking after sending it, when a newer
stream may have recorded its own; it now sends the node a full instead.

Kristoffer Dalby f07a384fe5 mapper: bound how long one node can block a batcher worker 
A node that drained slower than it was sent to held the worker for its
whole bundle; once its sends have waited 50ms, the rest waits a tick.
 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 90dc1d1caa 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 19:06:05 +00:00
Kristoffer Dalby 95c3c2e806 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 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.

Kristoffer Dalby dfa06e1aac state: say a taken name is already taken 2026-10-28 19:06:05 +00:00
Kristoffer Dalby bf03d4c01b 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 ab6f08ebc9 auth: answer a logout that deletes an ephemeral node as authorised 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 0449866cf3 cli: show a node's own ephemeral flag instead of its key's 2026-10-28 19:06:05 +00:00
Kristoffer Dalby d0f0344265 gen/client/v1: regenerate for the node ephemeral flag 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.

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 d48b62096a 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`.

Kristoffer Dalby 54253965cd hscontrol: arm the ephemeral GC at pre-auth key registration 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 93dbfa0a41 hscontrol: skip garbage collecting a node that is no longer ephemeral 2026-10-28 19:06:05 +00:00
Kristoffer Dalby c73615d6f9 db: wrap the sequential IP allocator so freed addresses are reused 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.

Kristoffer Dalby c5b9317c45 noise: stop serving metrics inside the tunnel 
Any machine key reached it, bypassing metrics_listen_addr. No client
asks for it.
 2026-10-28 19:06:05 +00:00
Kristoffer Dalby 85852dcb7d hscontrol: bound client-chosen text in request logs 
Clip at the sinks: handler errors, the request line, SSH local_user.
 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 70fc2db938 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.

Kristoffer Dalby 1f42a50489 .github: regenerate integration test workflow 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.

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.

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 f2b075083d 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 19:06:05 +00:00
Kristoffer Dalby b140580d37 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 19:06:05 +00:00
Kristoffer Dalby b9d35f5397 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.

Kristoffer Dalby b26dd72046 policy, state: log only the routes auto-approval adds 2026-10-28 19:06:05 +00:00
