fix(state): reclaim an onboarding lock whose run is gone by Dongni-Yang · Pull Request #10845 · NVIDIA/NemoClaw

Dongni-Yang · 2026-09-02T02:58:51Z

Summary

Interrupting nemoclaw onboard can leave onboard.lock under the gateway state directory. Every stateful command routes through the legacy-port migration gate, which previously refused on the mere presence of that file. Consequently, commands such as nemoclaw list and nemoclaw uninstall remained blocked even after the owning process had exited.

This change classifies a stable, bounded lock snapshot instead of counting the path:

Lock state	Result
Absent	proceed
Live PID with matching strong process identity	refuse and name the verified owner
Live PID without strong identity evidence	fail closed with cautious manual-recovery guidance
Foreign or unknown host/PID-namespace provenance	fail closed without consulting the local PID table
Reused PID with a different strong identity	proceed
Departed PID	proceed
Invalid or incomplete record newer than 30 seconds	refuse and request a retry after 30 seconds
Invalid or incomplete record settled for more than 30 seconds	proceed
Non-regular, unreadable, changing, or oversized path	refuse safely

Closes #10779

Why this is safe

Onboarding acquisition and legacy migration now use one strict classifier for record parsing, the 30-second incomplete-write grace period, host and PID-namespace provenance, process liveness, and PID reuse. Their filesystem readers retain their path-specific protections: no symlink following, regular-file validation, a 64 KiB read bound, descriptor-based metadata, and stable-read checks.

Migration never unlinks onboard.lock. It only stops treating a proven-stale generation as a migration blocker. The onboarding writer remains the sole cleanup authority and atomically renames a stale candidate, verifies its device and inode, then deletes only that generation or restores a raced replacement. The migration-lock handshake is unchanged: migration holds .gateway-state-migration.lock while checking onboarding locks, and onboarding rechecks that migration lock after atomically claiming onboard.lock, so exactly one side wins.

The ownership predicate now delegates to the same full invariant as cleanup authority: pinned session directory, descriptor/path identity, regular-file type, and link count. A replaced or hard-linked lock therefore cannot be reported as owned.

Process identity

The neutral process adapter now owns process liveness and identity for onboarding, lifecycle locks, and Shields:

Linux strong identity combines the kernel boot ID (or btime) with /proc/<pid>/stat start ticks: linux:<boot-identity>:<start-ticks>.
Linux zombies are treated as departed even though kill(pid, 0) succeeds.
Onboarding deliberately does not use second-precision ps lstart values, because two PID generations can begin in the same second. If strong identity is unavailable, a live PID remains fail closed.
Existing lifecycle-lock and Shields persisted formats remain compatible; their portable fallback stays isolated behind the shared adapter.

New onboarding records persist stable host identity and Linux PID-namespace identity. Linux uses machine ID, macOS uses the platform UUID, and hostname is never accepted as reclamation authority; when stable host evidence is unavailable, the owner remains fail closed. Foreign owners are never classified through the local PID table. Legacy records without provenance remain fail closed even if their recorded PID appears departed locally; their recovery message asks the operator to verify every environment sharing the state directory before removing only that lock file.

Scope

This resolves the issue by recognizing departed or PID-reused onboarding owners as stale. nemoclaw list is still blocked by a genuinely live or unverifiable onboarding generation; exempting read-only commands from the migration gate would be a separate dispatch-policy change.

The portable stat-then-unlink residual window documented in #1281 is removed from stale cleanup. Onboarding and MCP lifecycle storage now reuse a neutral lock-generation reclaim primitive: atomic rename is the claim point, the moved device/inode is verified before deletion, and an unexpected replacement is restored without overwriting a newer owner. Both the initial snapshot and post-rename observation retain the 64 KiB bound.

If deletion of a claimed generation fails, the primitive restores it at the canonical path when no replacement exists. If the quarantine cannot be removed, the error names its exact retained path and gives verify-before-remove guidance; a replacement canonical owner is never overwritten.

The shared lifecycle-lock reader now enforces the same 64 KiB limit for asynchronous and synchronous main, deadline, reaper, and containment observations. Oversized generations fail before their body is read, report the exact affected path, and are restored unchanged if detected after an atomic reclaim claim.

If cleanup of a hard-link publication candidate fails, the exact retained path is surfaced in a warning. A later acquisition performs a bounded candidate scan and generation-verified recovery: stale candidates from departed local owners are removed, while a candidate still linked to the canonical owner is preserved. Release and stale-generation recovery also remove only the inode-verified orphan candidate and preserve any replacement canonical owner. If post-reclaim candidate inspection itself fails, completed reclamation remains successful and the retained candidate plus inspection error are reported for recovery.

Onboarding lock publication now loops until the complete owner record has been written. A short or zero-progress write fails acquisition, closes the descriptor, and retires only the inode created by that attempt; the process never reports ownership of a partial record.

If release of a descriptor-owned onboarding lock fails, NemoClaw preserves the caller's result and emits an operator-visible warning with the exact lock path, cleanup error, and verify-before-remove guidance.

Test plan

Focused changed suites pass locally across lock classification/acquisition/ownership/storage, legacy-port migration, rebuild/destroy contention reporting, process identity, messaging-plan persistence, and onboarding machine transitions and repair.
Linux CI covers the complete migration and /proc identity cases that cannot be asserted faithfully on macOS.
New direct adapter coverage verifies Linux boot identity plus start ticks, btime fallback, zombie handling, bounded portable probing, preserved Shields format, and empty/failed probe behavior.
Regression coverage verifies departed owners, exact PID reuse, strong-identity matches, legacy/unverifiable live PIDs, incomplete-write settling, read races, oversized files, FIFOs, non-regular paths, replaced lock paths, hard-linked locks, failed quarantine deletion, canonical restoration, and retained-quarantine diagnostics.
The cross-process onboarding lock suite passes, including exact operator recovery diagnostics and a deterministic two-writer barrier proving exactly one durable recovery write.
npm run validate:pr passes against refreshed upstream main.
npm run typecheck, npm run checks:repository, and all 33 codebase growth guardrails pass; source architecture remains within budget with zero cycles.

Summary by CodeRabbit

Bug Fixes
- Improved onboarding lock handling to distinguish active, stale, changing, foreign, and unverifiable locks.
- Prevented unsafe or oversized lock files and paths—including hard-linked files—from blocking or compromising onboarding.
- Improved detection of reused process IDs and inactive or zombie processes.
- Added safer stale-lock reclamation with recovery from abandoned attempts and cleanup failures.
- Preserved recovery state when legacy or unverifiable lock owners are encountered.
- Added clearer lock ownership, safety guidance, and recovery details during onboarding, rebuild, and sandbox cleanup.

Interrupting `nemoclaw onboard` leaves `onboard.lock` under the gateway state directory. Every stateful command routes through the legacy-port migration gate, which refused on the mere presence of that file, so `nemoclaw list` and `nemoclaw uninstall` on that gateway port failed with a message telling the user to "finish or stop that run" when no run was left to stop. Deleting the file by hand restored operation. Classify the lock instead of counting it. The recorded holder decides liveness: a lock is held only while its recorded pid is alive, an owner-less body stays authoritative only while it is still changing, and absence, a departed holder, or settled owner-less debris all clear. The refusal now names the process, its start time, and its command. Every state that still refuses is one the presence check also refused, and every state that clears is one `acquireOnboardLock` would itself reclaim, so the gate is strictly relaxed and never disagrees with the onboard writer in the unsafe direction. The lock is not unlinked here: the writer reclaims it under an inode check, and unlinking a foreign path from this side would reopen the race that check closes. A recycled pid still reads as held. That is the conservative side of the writer's own rule, whose start-time comparison is not reproducible from this side without the wall-clock arithmetic that a clock step defeats.

📝 Walkthrough

Walkthrough

Onboarding and migration locking now use shared process provenance, bounded lock reads, generation-checked reclamation, and regular-file locking. Lock contention reports holder details and remediation. Tests cover stale, foreign, incomplete, oversized, non-regular, PID-reuse, and replacement-race cases.

Changes

Onboarding lock recovery

Layer / File(s)	Summary
Process identity and provenance `src/lib/adapters/process/identity.ts`, `src/lib/state/mcp-lifecycle-lock-identity.ts`, `src/lib/state/onboard-session/lock-holder.ts`	Adds cached host, PID-namespace, process-start, and liveness identities. Lock classification now fails closed when provenance is unavailable and retains foreign or legacy owners.
Generation-safe lock ownership `src/lib/state/lock-generation/storage.ts`, `src/lib/state/onboard-session.ts`, `src/lib/state/onboard-session/index.ts`	Adds bounded observations, atomic quarantine-based reclamation, complete lock publication, verified release, replacement preservation, and structured contention metadata.
Lifecycle-lock storage `src/lib/state/mcp-lifecycle-lock-storage.ts`, `src/lib/state/mcp-lifecycle-lock-acquisition.ts`	Bounds lock reads and recovers retained candidates. Reclamation validates generations, inode linkage, ownership, and replacement state.
Legacy migration handling `src/lib/state/legacy-port-migration.ts`	Regular-file migration locks use generation-aware acquisition and release. Legacy directory locks fail closed instead of being reclaimed. Registry locks use the same regular-file implementation.
Validation coverage `src/lib/state/*test.ts`, `src/lib/adapters/process/identity.test.ts`	Adds coverage for identity evidence, stale and foreign locks, oversized and non-regular files, incomplete publication, hard links, and replacement races.

Contention reporting

Layer / File(s)	Summary
Command contention handling `src/lib/actions/sandbox/destroy.ts`, `src/lib/actions/sandbox/destroy-preflight.ts`, `src/lib/actions/sandbox/rebuild-preflight-guards.ts`, `src/lib/onboard/portable-retirement-authority.ts`	Uses standardized lock-holder reasons and remediation. Detailed output is limited to unverified holder identity.
Flow regression coverage `src/lib/actions/sandbox/*test.ts`, `test/package-contract/destroy-model-router-flow.test.ts`	Verifies router and session state remain unchanged during foreign or unverified lock contention.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to 9aace

The PR adds generation-aware onboarding-lock reclamation so stale locks no longer block stateful commands, but a fallback release path can still remove the canonical lock without verifying that it has only one link. A local filesystem actor could leave the old generation reachable while a new lock is acquired, so this bounded lock-integrity risk should be fixed or explicitly accepted before merge.

The settling window compared against the timestamp captured before the open. A writer that replaced a settled lock in that window left a fresh body behind a stale timestamp, so the gate cleared a lock that was still being written. Read the timestamp from the opened descriptor instead. Refs #10779 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Dongni-Yang · 2026-09-02T03:37:56Z

Applied the CodeRabbit finding in b039b2e — good catch, it was a real hole.

The settling window compared Date.now() against the mtime captured by lstatNoFollow before openSync. If a writer replaced a settled owner-less lock in that window, the classifier judged a fresh body by the previous inode's timestamp and returned clear while the new lock was still being written. It now reads mtimeMs off the opened descriptor, so the timestamp and the bytes always come from the same inode.

Not separately pinned by a test: discriminating the two timestamps requires losing a real lstat/open race, which needs an injected seam rather than a fixture. The existing settling and reclaim cases cover the branch itself and still pass 27/27.

Unrelated to this PR: cli-test-shards (12) is red on main and fails identically on every open PR (reproduced on #10759 and #10760, both unrelated diffs). Root cause and details are in #10838 (comment).

The byte limit was checked against the size fstat reported, then the whole file was read. acquireOnboardLock creates the lock with openSync(..., "wx") and writes the payload afterwards, so the body can grow between those two calls and the limit was advisory.

Closing this PR so the fix can be rebuilt from current main around the smaller architecture that became clear only after the Review Advisor and CodeRabbit feedback exposed repeated ownership, identity, filesystem, and reclamation races.

The initial change addressed the right defect: an interrupted onboarding run leaves onboard.lock, and the legacy migration gate blocks list and uninstall based only on path presence. During review, each attempt to make automatic reclamation safe expanded the branch into shared process identity, generic lock-generation storage, MCP lifecycle locks, Shields-adjacent authority, rebuild, and destroy behavior. That review work was valuable because it revealed the actual boundary, but the resulting 30-file implementation is broader than #10779.

The replacement architecture will follow these rules:

Add one onboard-specific observer that returns absent, stale, or structured busy evidence.
Read one bounded, stable, no-follow regular-file snapshot and classify provenance before consulting the local PID table.
Treat only a proven-local departed process generation or exact PID reuse as stale.
Keep legacy, foreign, malformed, changing, oversized, linked, unreadable, or otherwise unverifiable locks fail closed.
Let the legacy migration gate proceed past a proven-stale lock without deleting it.
Keep physical cleanup owned by the onboarding protocol; normal release requires the descriptor retained by acquisition.
Do not introduce a universal lock framework or change MCP lifecycle and Shields protocols in this fix.

The generic rename-first, verify-after reclamation added during review will not be carried forward. Verification after rename cannot make the rename conditional on the previously observed generation and can temporarily vacate an active replacement's lock path.

The new PR will preserve the useful process-generation and provenance analysis from this review history while presenting a small, directly reviewable diff. Thank you to everyone who surfaced the conditions that made the simpler architecture visible.

## Outcome Handled `SIGINT` and `SIGTERM` during onboarding now release the owned onboarding lock before the process re-raises the signal. If another exit leaves a lock, commands stop with safe instructions to verify ownership and remove only that lock. ## Reason An interrupted onboarding run could leave `onboard.lock`, which blocked `nemoclaw list` and `nemoclaw uninstall` for the gateway. The previous error did not give a safe recovery procedure. ### Related issues Fixes #10779 Refs #10845 Supersedes #10899 ## Changes - Release the descriptor-owned onboarding lock from the existing `SIGINT` and `SIGTERM` failure handler before re-raising the signal. - Remove PID-only fallback deletion; a process without the retained descriptor has no cleanup authority. - Give migration users lock-specific manual recovery instructions without deleting or rewriting the lock. - Cover real subprocess signal cleanup, foreign same-PID preservation, and unchanged lock and recovery files. ## Verification - `npx vitest run --project cli src/lib/onboard/exit-step-failure.test.ts src/lib/state/onboard-session.test.ts src/lib/state/legacy-port-migration.test.ts` — 3 files and 111 tests passed. - `npm run test:changed` — completed successfully; 45 growth-guardrail tests passed. - `NODE_OPTIONS=--max-old-space-size=5120 npm run validate:pr` — passed against canonical `main` at `ae5b2ca922023120f90e23242c133c774ae30aa0`. - [CI / Pull Request](https://github.com/NVIDIA/NemoClaw/actions/runs/34402395087) — passed for exact head `e732ec7f2a0a285631d7ec224a9e781e868021f8`, including all 12 CLI shards. - [E2E / Self-Hosted PR Qualification](https://github.com/NVIDIA/NemoClaw/actions/runs/34402396342) and security scans — passed for the exact head. - [PR Review Advisor](https://github.com/NVIDIA/NemoClaw/actions/runs/34404142532) — all nine specialists completed with no actionable finding. - CodeRabbit reviewed the exact six-file diff. Its only finding requested an assertion already present in the reviewed test; the thread records that evidence and is resolved. - GitHub commit verification — all 17 PR commits through `e732ec7f2a0a285631d7ec224a9e781e868021f8` are verified. - Diff review and secret scan — no secrets, API keys, or credentials added. ## Review notes This PR changes `src/lib/onboard/**`, a contributor-sensitive path. Earlier maintainer change requests applied to the removed observer design. The narrowed signal-cleanup candidate requires current maintainer review. The issue reproduced on DGX Spark; no manual Spark run was performed. Repository policy does not require hardware evidence because this PR does not change `scripts/prepare-dgx-station-host.sh`. The real subprocess test covers the signal and lock boundary. The exact-head managed-image workflow has one inherited failure: Hermes rejects the stale `image-build-probes.py` digest. Canonical `main` reproduces the same failure in [run 34401831766](https://github.com/NVIDIA/NemoClaw/actions/runs/34401831766). The isolated repair is [#11338](#11338); this PR does not include that unrelated image change. --- Signed-off-by: Julie Yaunches <jyaunches@nvidia.com> --------- Signed-off-by: Julie Yaunches <jyaunches@nvidia.com>
