fix(onboard): move the portable sandbox subnet out of link-local - #9714
Conversation
`nemoclaw onboard --experimental-profile portable` failed deterministically at network creation. Podman's netavark backend refuses to allocate any bridge network inside the RFC 3927 link-local block, so creating the sandbox network on 169.254.1.0/24 always returned "subnet 169.254.1.0/24 is already used on the host or by another config" and onboarding aborted before any sandbox, registry, or gateway state existed. The sandbox subnet and the managed registry address now use 10.87.0.0/24. That range sits below Podman's own 10.88.0.0/16 bridge and every base in its default_subnet_pools, and outside Docker's 172.16.0.0/12 and 192.168.0.0/16 default pools, so neither runtime allocates it for another network. The host gateway keeps its 169.254.2.2/32 loopback alias. Netavark validates bridge subnets, not loopback aliases, so that address is unaffected, and #9587 placed it outside the sandbox subnet on purpose. A host onboarded before this change keeps a network on the retired subnet, which the reuse guard would reject with a message that does not say what to do. Name the retired subnet so that host gets the removal command instead. Refs: #9587 Closes: #9707 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

CHANGE REQUEST REVIEW BLOCK
This review blocks merge at commit 67e1fe58169b69014f45bb7aba7c60dec070d157 until the retired-subnet recovery is ownership-aware and can complete without --force. The exact required correction and regression evidence are recorded in #9714 (comment).
The retired-subnet guidance named `podman network rm` on its own. Podman refuses that removal while a container is attached, and the managed registry can still be attached because the network check runs before the registry step. `network rm --force` would clear the attachment but also deletes containers NemoClaw does not own, so it is not an acceptable instruction. Inspect the registry for the NemoClaw ownership label before naming anything for removal. An owned registry gets an ordered recovery that removes the registry first and the network without `--force`. A container that does not carry the label is never named for removal; the operator resolves it. The retired-subnet path still performs no mutation of its own. The retired-subnet cases move to their own test file. Adding them in place put portable-host-preparation.test.ts over the 1500-line budget. Refs: #9707 Signed-off-by: Dongni Yang <dongniy@nvidia.com>

Addressed in 7eeb9e7. The finding was correct: Ownership check before any name is printed.
I chose ordered guidance over automatic migration. Automatic removal on an upgrade path mutates host state before the operator has seen the diagnosis, and the recovery is two commands. The retired-subnet path still issues no mutating command of its own. Coverage is in the new The cases went to their own file because adding them in place put Docs in Verification: Still unreproduced on hardware, as noted in the description — I have no DGX Spark or rootless Podman host, so the netavark rejection and this recovery path are verified statically and at unit level only.

Thanks for the update. I am keeping CHANGES_REQUESTED on 7eeb9e7. This needs another code revision before the final rootless Podman test. The current check looks only for Please update the code to inspect all running and stopped containers connected to the retired network through the verified current-user Podman socket. This is a local Podman check; no files, logs, or sensitive data should be uploaded. If inspection fails or any other container is connected, stop without showing removal commands. Show ordered commands with full container and network IDs only when the network is empty or the verified NemoClaw registry is its sole connected container. Add the matching negative tests and docs, narrow the Docker pool claim, and select the rootless PR test that proves non-force removal by full network ID. This remains blocked until those changes land and the maintainer rootless check passes. |

The recovery guidance checked only the managed registry by name. Any other running or stopped container connected to the retired network also blocks a non-force removal, so the printed commands could still fail. A failed registry inspection was also read as absence, which produced removal guidance from evidence that was never obtained. Enumerate every container connected to the retired network through the verified current-user Podman socket, including stopped ones. Print ordered removal commands, with full container and network IDs, only when the network has no connected container or the verified NemoClaw registry is its sole connected container. Any other container, or any probe that cannot be read, stops onboarding with no removal command at all. Join the container inspection fields with an explicit separator. A missing ownership label renders as `<no value>`, which contains a space, so whitespace splitting misread both the label and the network address.

The recovery said the sequence used no `--force` while printing `podman rm -f`, and the documentation told an operator to remove a foreign container that onboarding had just refused to name. Print `podman stop` then `podman rm` for the verified registry, so every printed step is force-free and matches what the text claims. For a container NemoClaw does not own, the documentation now requires identifying the owner and confirming removal is safe, and says to leave the container in place and use a separate recovery process otherwise.

Landed across Inspect all connected containers, running and stopped. Inspection failure is no longer absence. The network-identity probe, the connected-container list, and the ownership inspection all go through Stop without removal commands. Commands print only when the network has no connected container, or the sole connected container is named Full IDs. Network ID from Negative tests. Four refusal cases and three foreign-container cases, each asserting no mutating command was issued and that the message contains no Docker pool claim narrowed. The description no longer asserts a documented Docker default. Two further corrections from this round's review, both of which I agree were wrong in my previous push:

Reviewed exact head .\n\nSecurity verdict: PASS — no blocking findings. The retired-subnet path fails closed, reasserts the verified current-user Podman socket around every read, inventories running and stopped attachments, accepts only an empty network or the sole exact NemoClaw-owned registry, and emits full 64-character IDs in ordered non-force commands without performing mutation. The PR workflow uses an ephemeral GitHub-hosted runner, read-only token access, credential-free exact-SHA checkout, and the exact-head rootless proof passed all phases.\n\nThe remaining CodeRabbit note is non-blocking test maintainability and does not weaken the contract or evidence.\n\n@senthilr-nv, the conditions in the older change-request review appear satisfied at the current head; please clear or refresh that review when ready.
Resolved on the current commit. Recovery verifies the exact managed registry ownership label and complete attachment set, emits an ordered force-free stop/remove/network-remove sequence only for the sole owned registry, refuses ambiguous or unmanaged cases, and keeps documentation and focused tests aligned.

Summary
nemoclaw onboard --experimental-profile portablefailed deterministically at network creation. Podman's netavark backend refuses to allocate any bridge network inside the RFC 3927 link-local block, so creating the sandbox network on169.254.1.0/24always returnedsubnet 169.254.1.0/24 is already used on the host or by another config, and onboarding aborted before any sandbox, registry, or gateway state existed. The sandbox subnet and the managed registry address now use10.87.0.0/24, which both runtimes leave free.Related Issue
Closes #9707
Changes
src/lib/onboard/experimental/portable-profile.ts—PORTABLE_DOCKER_NETWORK_SUBNETmoves from169.254.1.0/24to10.87.0.0/24, andPORTABLE_REGISTRY_IPfrom169.254.1.3to10.87.0.3, preserving the existing host offset. The bridge gateway follows to10.87.0.1; production code reads it fromdocker network inspect(src/lib/onboard/gateway-sandbox-reachability.ts:182) and never hardcodes it, so no other production value changes.src/lib/onboard/experimental/portable-host-preparation.ts— the network reuse guard rejected a pre-existing network on the old subnet with a message that did not say what to do. It now names the retired subnet and, only after proving the network is empty or holds nothing but the verified NemoClaw registry, prints an ordered force-free removal sequence. This follows theRETIRED_PORTABLE_HOST_GATEWAY_IPprecedent from Portable gateway address overlaps the sandbox network #9587 in the same file.src/lib/onboard/experimental/portable-retired-subnet-recovery.test.ts— new focused suite for that recovery path.test/e2e/live/portable-cpu-delegation-proof.test.ts,test/helpers/hermes-portable-ollama-test-harness.ts, and the remaining test fixtures follow the new address values and the new inspection field separator.docs/inference/set-up-openai-compatible-endpoint.mdx— new address values, and a recovery section that matches what the code actually prints.Why this range
The claim I can source precisely is about Podman, which is the runtime that fails here.
containers/commonshipsdefault_subnet_poolswith bases10.89.0.0/16,10.90.0.0/15,10.92.0.0/14,10.96.0.0/11, and10.128.0.0/9. Together those cover10.89.0.0-10.255.255.255.10.87.0.0/24is below all of them and below Podman's own10.88.0.0/16default bridge, so netavark does not auto-allocate it.For Docker I am deliberately not asserting a documented default.
dockerddocumentation does not state the effective default fordefault-address-pools; itsdaemon.jsonexample shows172.30.0.0/16and172.31.0.0/16at size 24, which is an example rather than a stated default. What I rely on is narrower and checkable:10.87.0.0/24is not in the172.16.0.0/12space Docker bridges conventionally occupy, and not in192.168.0.0/16. A host that has explicitly configureddefault-address-poolsover10.87.0.0/24would still collide, and the retired-subnet guard would report that as an unexpected subnet rather than silently reusing it.The issue suggested
10.250.1.0/24. That address is inside netavark's10.128.0.0/9pool base, so Podman could allocate it to an unrelated network and reproduce the same "already used" failure from the other direction.Why the host gateway does not move
PORTABLE_HOST_GATEWAY_IPkeeps169.254.2.2/32. Netavark validates bridge subnets, not loopback aliases, so that address is not affected by this defect. #9587 placed it outside the sandbox subnet deliberately, and moving it would additionally churn the TLS SANs (docker-driver-gateway-local-tls.ts:198,219), the gateway TOML (docker-driver-gateway-config.ts:625), the endpoint URLs (docker-driver-gateway-env.ts:113,253), and would require a second retired-address migration.Why not probe the backend's allowed ranges
The issue offered this alternative. Netavark exposes no machine-readable allowed-range API — the only signal is the error string, and classifying by stderr text is the failure mode #9308 removed. A probed subnet would also make the frozen authority digest in
hermes-portable-ollama-authority.tshost-dependent, invalidate pinned gateway certificate SANs across a re-onboard, and turn the single retired-address preflight into a persisted history. That is a new supported surface for address selection and belongs behind the Product Scope Gate, not in a release-blocker fix.Type of Change

169.254.0.0/16is never operator-trustable, while10.0.0.0/8is (src/lib/security/trusted-private-endpoint.ts). Both stay blocked for MCP targets (src/lib/security/mcp-url-target.ts).

7eeb9e783bmade the retired-subnet recovery ownership-aware.4a441a025aextended it after review: the check now enumerates every running and stopped container connected to the retired network through the verified current-user Podman socket, and prints removal commands with full container and network IDs only when the network is empty or the verified NemoClaw registry is its sole connected container. A foreign container, or any probe that cannot be read, stops onboarding with no removal command at all.That round also fixed a parsing defect the first version introduced: a missing ownership label renders as
<no value>, which contains a space, so whitespace splitting misread both the label and the network address. The inspection fields now use an explicit separator, which also repairs the same latent misparse in the pre-existingensureRegistryContainerreader.Review round 3
8ddf0600daclosed the last gap between what the message promised and what it printed. The registry case said "without--force" while printingpodman rm -f, so it now printspodman stop <id>,podman rm <id>, thenpodman network rm <network-id>— no step uses--force. The documentation section was rewritten to match: the ordered force-free sequence, the foreign-container case where NemoClaw names nothing and the operator must identify the owner first, and the failed-probe case.Coverage added
The new cases live in
src/lib/onboard/experimental/portable-retired-subnet-recovery.test.ts(10 tests) rather than inportable-host-preparation.test.ts. Adding them in place pushed that file to 1540 lines, past the 1500-line growth budget, so the recovery path got its own focused suite.The suite pins that the sandbox subnet and registry address sit outside
169.254.0.0/16— which fails on the pre-fix constants — and pins each refusal message: empty network, verified sole registry, foreign container, registry sharing the network, same-name container without the ownership label, and each of the four probe failures. The refusal cases assert both that no removal command was issued and that none appears in the message text.portable-host-preparation.test.tskeeps the existing#9587contract test's intent — the host gateway stays outside the sandbox subnet — but its assertion that the retired169.254.1.2falls inside that subnet was removed rather than re-valued, because it is meaningless once the subnet is no longer link-local.Not reproduced on hardware
The failing configuration is a DGX Spark with rootless Podman 4.9.3 and netavark 1.4.0, which I do not have. Verification here is static and unit-level. The reporter's own probe on the failing host confirms the range class works:
podman network create --subnet 169.254.1.0/24fails, and an ordinary private/24succeeds. A maintainer with the reporter's host should confirm the portable onboard reaches Ready.Failing check on this head
cli-test-shards (9)is red at8ddf0600da, which also failscli-testsandchecks. It is not caused by this change. The shard exhausted the 4 GB Node.js heap intest/onboard-selection.test.ts:1472, and the reportedAssertionError: null !== 0is the spawned child's status after the OOM kill, not a behavior assertion. That is the same failure PR #9725 ("fail closed on unscripted child prompts") was opened to fix, from the same unbounded model-selection retry loop. This PR touches no file in that suite's import graph.Pre-existing failures on this base
