WalkthroughThe test helpers now flush ChangesMCS nftables rule handling
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The tests now temporarily remove MCS-blocking nftables rules to retrieve ignition data, but failed cleanup can silently leave those rules removed and affect later tests. Handle restoration failures before merging. Suggested reviewers: Important Pre-merge checks failedPlease resolve all errors before merging. Addressing warnings is optional. ❌ Failed checks (1 error)
✅ Passed checks (14 passed)
Full details: Docstring CoverageExplanation No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 4 files. Full details: Stable And Deterministic Test NamesExplanation No test title changed in the pull request. The added code contains no Full details: Test Structure And QualityExplanation PASS. The PR changes only related ignition-access setup and cleanup. All three test call sites defer nftables restoration, and no new cluster-scoped resource lacks cleanup. The existing MCS checks use bounded Eventually calls (1–6 minutes with 20-second polling). New flush assertions include node-specific failure messages. No new Eventually or Consistently call lacks a timeout, and the changes follow the existing deferred iptables cleanup pattern. Full details: Microshift Test CompatibilityExplanation PASS: The pull request adds no new Ginkgo Full details: Single Node Openshift (Sno) Test CompatibilityExplanation PASS: The patch adds no new Ginkgo test declarations. It only updates existing tests and adds nftables helper methods. The affected tests select one master or one pool node and run commands on that node. They do not require multiple nodes, distinct-node scheduling, HA failover, scaling, anti-affinity, or separate node roles. These operations are compatible with SNO. Full details: Topology-Aware Scheduling CompatibilityExplanation PASS: The pull request changes only extended-privilege test helpers and test flows. The verified diff adds nftables flush/restore calls and does not add or modify deployment manifests, operators, controllers, replicas, affinity, topology spread, node selectors, tolerations, or PDBs. The topology-aware scheduling check is therefore not applicable. Full details: Ote Binary Stdout ContractExplanation No OTE stdout contract violation is introduced. The PR adds only Full details: Ipv6 And Disconnected Network Test CompatibilityExplanation PASS. The commit adds no new Ginkgo test declaration. Its added code only lists, flushes, and restores the cluster-local Full details: No-Weak-CryptoExplanation PASS. The HEAD diff adds only nftables rule flush/restore calls and test setup. The new code uses Full details: Container-PrivilegesExplanation PASS. The pull request changes only four Go files under Full details: No-Sensitive-Data-In-LogsExplanation The pull request adds logs that include Resolution Remove node names from the new log and assertion messages, or replace them with a non-sensitive identifier. Restore nftables rules through stdin or a temporary file instead of embedding them in the command argument. Ensure failure logging does not include raw command arguments, nftables rules, or unsanitized command output.

- Line 405: Update GetMCSIgnitionConfig to capture the error returned by the
deferred RestoreNftablesMCSBlockingRules call and propagate it when the main MCS
request succeeds, while preserving the primary operation error if one already
occurred.

Covers the separate nft list error-swallowing site described in the consolidated
comment.
In `@test/extended-priv/node.go`:
- Around line 1228-1229: Update the restoration flow around DebugNodeWithChroot
to avoid interpolating savedRules into bash -c: write the raw rules to a remote
temporary file, then invoke nft -f against that file. Preserve the existing rule
restoration behavior while ensuring apostrophes and crafted content cannot alter
shell parsing or execute commands.

We realised that tests 42520 and 76587 are impacted too. We remove the ntf chain too in those tests. Manually launched executions: |

- What I did
Remove the nft chain blocking the access to the ports 22623 and 22624 before getting the ignition config served by the MCS.
- How to verify it
Test PolarionID:85749 should pass.
Test PolarionID:42520 should pass.
Test PolarionID:76587 should pass.
