Problem

Gateway embedders duplicate the relay's authorization, origin scoping, and stats attribution. Their sessions can outlive a revoked or narrowed grant. Custom signed payloads also require a second JWT decoder, and the auth server cannot read a JWK Set.

Approach

  • Put cadence, expiry, nudges, and jittered retry scheduling on lease::Producer; the HTTP auth client uses that same clock.
  • Expose Cluster::admit with a live lease, role-scoped origins, and tiered stats. Use it in both native and io_uring QUIC paths; add auth::hold for gateway work.
  • Add gateway transport and lease-reason values, signed-payload Key.decode in Rust and JS, and moq auth serve --key-set.
  • Cover grant updates, revocation, narrowing, role denial, key IDs, and contract round trips in tests. Scoped just check, just test, and full cross-language smoke passed locally.

Impact

  • Rust API adds lease::Producer::due/failed, lease::Due, Cluster::admit, cluster::Admitted, auth::hold, auth::Error::Forbidden, Key::decode, and serve::Keys::Set.
  • JS API adds Key.decode and accepts rtmp, srt, and webrtc in the strict transport schema.
  • Auth JSON adds those transport values and named narrowed/shutdown end reasons. end.reason remains an open string.
  • A JWT verified with one key must now carry the same kid as that key. A missing kid is accepted only if the key also has none.
  • CLI adds moq auth serve --key-set FILE, mutually exclusive with --key and --key-dir.
  • Breaking for moq-auth 0.1 (targets dev): Transport and serve::Keys gain variants and become #[non_exhaustive]. cluster::Admitted is #[non_exhaustive], and its lease carries the admitted stats, so a re-checked tier retags gateway sessions too (feat(relay): retag a live session's stats when a re-check moves its tier #4057). moq-relay passes cargo semver-checks.
  • The relay session filter accepts every transport spelling, including the gateway ones.

Alternatives

  • Keeping gateway admission and lease scheduling outside the relay duplicates its security and stats logic.
  • Continuing to ignore kid for a single key leaves file, directory, and JWK Set verification inconsistent.

P1 Badge Retarget the single-key kid break to dev

When a configured key has a kid, this now rejects every previously valid token that omits the header, although single-key verification intentionally accepted those tokens before this commit. Because moq-auth is a published 0.1.x package and this commit targets main, that behavioral compatibility break must be moved to dev rather than shipped as an additive feature on main; the equivalent JavaScript change should move with it.

Walkthrough

The changes add JWK Set key selection to Rust auth serving and the CLI, and add payload decoding APIs in JavaScript and Rust. Lease producers now schedule revalidation, expiry, and retry delays. Rust and JavaScript auth contracts add RTMP, SRT, and WebRTC transport identifiers, plus narrowed and shutdown close reasons. Relay admission now returns scoped origins and session stats through the cluster, and gateway work can be held against lease termination.

Priority: ➖ Normal

Merge Risk: ⚪ Minimal · up to 08ab8

Lease scheduling is overflow-safe, the decode test awaits its positive assertion, and the lease-clock documentation is accurate. No merge-blocking risk remains.

Name lease::Producer as the re-check clock owner.

The phrase “consumer of a lease::Producer” can suggest that a consumer handle owns due(), update(), and failed(). These methods and the clock belong to Producer. The following paragraph repeats their behavior. Keep the method details there and remove the duplicate summary.

Await the .resolves assertion.

The assertion on Key.decode is not awaited. The test can finish before the promise settles. If decode then rejects or returns another payload, this test does not fail. This is the main positive case of the test, so it must be enforced.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Compute the first re-check with checked_add so a large revalidate cannot panic.

Clock::new computes tokio::time::Instant::now() + cadence, and this addition panics on overflow. cadence is grant.revalidate, which comes from the auth server's reply. If that reply carries a very large value (for example u64::MAX seconds), the following happens:

  • Producer::new panics inside Client::connect.
  • Producer::update panics while it holds the clock Mutex. This poisons the Mutex, so every later due(), failed(), or immediate() call panics on .expect("lease clock").

Treat a cadence that cannot be represented as "no scheduled re-check". The expires bound still ends the lease.

 	fn new(grant: &Grant) -> Self {
 		Self {
-			next: grant.revalidate.map(|cadence| tokio::time::Instant::now() + cadence),
+			next: grant
+				.revalidate
+				.and_then(|cadence| tokio::time::Instant::now().checked_add(cadence)),
 			expires: grant.expires,
 			cadence: grant.revalidate,

Based on learnings: "avoid computing Instant/SystemTime deadlines via direct arithmetic like time + duration, which panics on overflow; use Instant::checked_add(duration)".

Preserve publish-capable roles when mapping future variants.

moq_net::Role is non-exhaustive. If a future variant permits publishing, this wildcard maps it to Subscriber, and Cluster::scope removes the publisher origin. The Tokio conversion uses the same mapping, so this affects both paths. Map unrecognized variants to None in both conversions; None is the documented bidirectional fallback.

P1 Badge Move exhaustive enum expansions to dev

Because moq_auth::Transport is public and lacks #[non_exhaustive], adding these variants makes downstream exhaustive matches fail to compile when updating the published 0.1.x crate. This is an API break independent of the already-reported kid behavior, so this main-targeted change needs to move to dev; the new serve::Keys::Set variant has the same compatibility problem.

P2 Badge Accept gateway transports in session filters

When an embedder registers one of these gateway requests in the public session::Registry, operator commands such as moq auth sessions --transport rtmp and moq auth revalidate --transport webrtc fail with HTTP 400: rs/moq-relay/src/session.rs::parse_transport still accepts only quic, iroh, websocket, tcp, unix, and http. Add the three new wire values to that parser and its filter tests so gateway sessions can be selected and nudged by transport.

Verdict: ITERATE

Positive improvement: yes. Centralizing lease cadence/expiry on lease::Producer, exposing Cluster::admit / Admitted, and adding auth::hold plus Key.decode / --key-set removes the duplicated gateway admission path the PR describes. Wiring both native and io_uring paths through the same admit helper, plus the embedder tests for grant update/revocation/narrowing/role denial, is the right shape.

Worth the complexity: mostly. Lease clock ownership on the producer, role-scoped origins, and kid-consistent verification are justified by the security/stats consistency goal. The intentional kid match when a key has an id (and gateway transport values) are documented breaks and fit a mainline auth surface, especially ahead of packaging.

Before merge, please fix or explicitly dismiss:

  1. Clock::new still does Instant::now() + cadence — a hostile or buggy auth revalidate near Duration max can panic the admit path; use checked_add and treat overflow as “no re-check” (or clamp).
  2. js/auth/src/key.test.ts positive Key.decode case uses expect(...).resolves without await, so a reject/wrong payload can pass.
  3. Optional hardening: map moq_net::Role exhaustively in the uring path (unknown → refuse) and ensure session filters accept the new gateway transports if operators will query by them.

Not a redesign: keeping admission outside the relay would reintroduce the duplication this PR removes. After the small stability/test fixes, this looks merge-ready.

Resolve conflicts: keep main's fixed expiry deadline, peer-change close, and
uring peer/SNI facts alongside the PR's gateway admission. Drop the finished
auth-embedder quest. Address review: checked cadence deadline, awaited
Key.decode test, exhaustive role mapping, and filterable gateway transports.

`client` and `serve` enabled `dep:tokio` without the `tokio` feature
that gates `lease::Producer::{due, failed}`, so moq-auth failed to build on
its own defaults; `tokio` also needs `rand` for the backoff jitter. Mark the
new `Admitted`, and the `Transport` and `serve::Keys` enums this PR already
extends, `#[non_exhaustive]` so the next field or variant is additive.

Merged main and addressed the ITERATE review. Auto-merge is not enabled: this needs a maintainer call on a published API break.

Blocker: cargo semver-checks against the published moq-auth 0.1.0 fails enum_variant_added: Transport::{Rtmp, Srt, WebRtc} and serve::Keys::Set extend exhaustive enums. moq-relay passes against 0.15.2. Per the repo rules this belongs on dev, but dev is 121 commits behind main, so a retarget means a rebase. Options:

  1. Accept moq-auth 0.2.0 from main. The crate shipped yesterday, and the break also lands #[non_exhaustive]. (Recommended)
  2. Retarget to dev and rebase.
  3. Split the PR: the additive lease clock, admit/hold, and Key::decode go to main. The new variants go to dev.

Changes:

  • Conflicts: kept main's fixed expiry deadline, peer-change close, and uring peer/SNI facts. Removed the finished quest.
  • Clock::new uses checked_add, with a regression test. The Key.decode test now awaits its assertion.
  • Role mapping is exhaustive (unknown maps to None) and shared by both paths. The session filter parses every Transport spelling.
  • Fixed a build break: default moq-auth did not compile because client/serve pulled in dep:tokio without the tokio feature.
  • Added #[non_exhaustive] on Admitted, Transport, and serve::Keys.

P2 Badge Return a revocation that wins during work completion

When work revokes its own producer before returning, or a concurrent revoke lands after lease.ended() was polled but before work returns, Lease::close returns the already-recorded revocation reason, but this branch discards it and reports Ok(result). This violates hold's contract that revoked work returns Err(reason); inspect the reason returned by close before treating the work as successfully completed.

Retarget to dev. Resolve against #4057: Cluster::admit attaches the
admitted stats to its lease, so a re-checked tier retags gateway and
native sessions alike.

Following the maintainer's call, retargeted to dev. dev first took main in 176662b. The only conflicts were in the quest files.

The PR's merge with dev conflicted with #4057 (stats retier). Cluster::admit now attaches the admitted stats to its lease, so a re-checked tier also retags gateway sessions. a_moved_gateway_tier_retags_its_stats covers this and fails without the fix. just check and the moq-relay and moq-auth tests pass. The title now has ! for the moq-auth break.
