Kristoffer Dalby 89647cac2f 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.

Kristoffer Dalby 464dba33e1 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.

Kristoffer Dalby 833ff6b053 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 cfd065c680 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 f192bf05b2 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 9482a1c6c3 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.

Kristoffer Dalby 7e995b1ff9 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.

Kristoffer Dalby 7343a7d0fc state: drop auto-approved routes when they are withdrawn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.

Kristoffer Dalby 664d3477f0 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 07:15:54 +00:00
Kristoffer Dalby e8d45606a0 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 6e3de18b5c 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.

Kristoffer Dalby 588a2f934c 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 1c17be4dd8 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, which takes it back with a
new node key. Another user's key or login adds that user's own device.

Kristoffer Dalby c48767eed6 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.

Kristoffer Dalby 54e2474146 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.

Kristoffer Dalby 850c5d3fbb 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 690fe40616 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.

Kristoffer Dalby 780c9406ae 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.

Kristoffer Dalby 2cb84b2905 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 00:51:39 +00:00
Kristoffer Dalby 9d5d397c1d 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 90f873ee66 policy: look up approved routes in a set when auto-approving
Avoid scanning the growing approval list for every announcement.

Kristoffer Dalby 2d2bfe8fd2 types: derive subnet and exit routes in one pass

Skip derivation when no routes are approved.

Kristoffer Dalby 4d007eb5e9 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.

Kristoffer Dalby 4cafc80fbd state, policy/v2: stop treating announced-only routes as policy changes
Policy evaluation reads only announced-and-approved routes.

Kristoffer Dalby 4d1e8aa0c1 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.

Kristoffer Dalby d59e14b197 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.

Kristoffer Dalby 7daa08e94e 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.

Kristoffer Dalby e6302ce9b6 policy/v2: refuse check SSH rules with tag sources
A check asks the source's user to log in again, and a tagged node has
none. Tailscale SaaS refuses the rule; headscale accepted it.
