fix(seaweedfs): keep Object Lock working for COSI credentials on SeaweedFS 4.48 by lexfrei · Pull Request #4893 · cozystack/cozystack

Aleksei Sviridkin (lexfrei) · 2026-10-13T05:27:54Z

What this PR does

Existing bucket credentials need additional Object Lock actions to work with SeaweedFS 4.48. The upstream COSI driver v0.4.0 from #5284 already grants them to new credentials. It does not grant access again for a ready BucketAccess, so older identities stay unchanged after the driver update. The custom COSI driver build and its image repository are no longer part of this PR.

This PR adds a post-install and post-upgrade hook that grants the actions implied by each identity's Read and Write permissions. Bucket restrictions and credentials stay unchanged, and Write does not grant governance bypass. The hook runs after the release update and does not guarantee Object Lock access during a server rollout.

The wrapper chart also declares its local dependency so Helm lint can check it. The chart remains on 4.45. #4879 is stacked on this PR for the 4.48 upgrade.

Unit tests and E2E passed on 9fa5d64. A focused Linux run of the hook's bats suite (20/20) and of make test in packages/system/seaweedfs also passed on that head. Live cluster validation has not been run.

Known hook limitations remain tracked in #4894. A pod that never starts can still fail the Helm action. Deletion between the dry run and apply can leave a keyless identity. Warning Events expire, the Job stays behind for its logs, and an identity name containing a newline can prevent the Event from being recorded.

Walkthrough

The change adds a script that grants missing SeaweedFS Object Lock IAM actions and reports incomplete or unreadable outcomes. When COSI is enabled, a Helm hook runs the script after installation or upgrade. New Bats and Helm tests cover the script and hook.

Changes: SeaweedFS COSI Object Lock actions

Layer / File(s)	Summary
IAM action migration `packages/system/seaweedfs/files/object-lock-actions.sh`, `hack/seaweedfs-object-lock-actions.bats`	The script plans and applies missing Object Lock actions with retries and input checks. It reports incomplete or unverifiable results and attempts to create a Warning Event. Bats tests cover grants, idempotence, read failures, unsafe inputs, and event reporting.
Helm hook resources and validation `packages/system/seaweedfs/Chart.yaml`, `packages/system/seaweedfs/templates/object-lock-actions-hook.yaml`, `packages/system/seaweedfs/tests/object_lock_actions_hook_test.yaml`	The chart declares a SeaweedFS dependency. When COSI is enabled, the hook creates a Job to run the script, with scoped event and HelmRelease permissions and optional security mounts. Helm tests cover rendering, configuration, mounts, and Job naming.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: Low · up to 93140

The hook grants the Object Lock actions to existing identities and reports failures. A stalled Kubernetes API during Event reporting could fail an otherwise successful install or upgrade, and an unusual identity name could suppress the warning Event. Both cases are narrow and easy to fix. Confirm that the COSI driver image used for new credentials grants these actions.

Explanation

The title names the affected component (seaweedfs), the symptom (Object Lock access for COSI credentials), and the target version (SeaweedFS 4.48). The changeset adds a grant script, a Helm hook that runs it, and tests for both. The title covers the main fix, though it does not mention the new hook or the script. It is specific and matches the objectives. Note: the chart stays on 4.45 in this PR, so 'on SeaweedFS 4.48' describes the reason for the fix, not the version the chart runs.

Minor · Functional Correctness · Quick win

Encode the Event message instead of removing two characters.

If an IAM identity name contains a newline, pending contains that newline. The sanitizer keeps it, so message: "$message" becomes invalid YAML. kubectl create then fails, but the Job exits successfully without the Warning Event. Encode the message as a JSON string before inserting it into YAML; JSON string syntax is valid for this YAML scalar. Based on learnings, manual escaping must also handle control characters in input strings. (raw.githubusercontent.com)

A plain newline doesn't break it: kubectl's YAML reader folds it into a space inside the quoted message, and the Event is created. It fails only when a line in the message starts with a document marker, --- or ... followed by a space or the end of the line. Then kubectl create fails, the script logs it, and only the Event is lost. Checking this found a real hole in the name filter, though. In jq's regex $ also matches before a trailing newline, so a name or action ending in \n got onto the weed shell command line. Both filters now use \z, with a bats case for each, in 9fa5d64.

@lexfrei Thanks for the correction. I was wrong to say that a plain newline necessarily makes the YAML invalid; it can be folded into a space.

I confirmed the \z filters and both regression cases in the source. I did not run the tests. The Event message still includes unencoded identity names, so the document-marker case you described remains. I’m not marking this finding as addressed.

SeaweedFS 4.48 requires dedicated Object Lock actions, but upgrading the COSI driver does not re-grant access for ready BucketAccesses. Add the actions implied by existing Read and Write grants after install and upgrade, without changing credentials or granting governance bypass.

Helm lint rejects the wrapper chart while its bundled seaweedfs chart is undeclared. Reference the local chart without constraining its version so vendoring remains the source of the dependency. Assisted-by: LLM Signed-off-by: Aleksei Sviridkin <[email protected]>
