OSAC-4236: Implement BCM GetHostNICs via BareMetalHost hardware details#467mennyaboush wants to merge 3 commits into
Conversation
BCMClient.GetHostNICs reads Status.HardwareDetails.NIC[] from the BMH CR via baremetalhost.Manager.GetHardwareNICs, lowercases all MACs, and returns the full list as HostNIC entries. Returns nil, nil when no NICs are present. Avoids a costly GetDevices call to the BCM REST API. Assisted-by: Claude Code <noreply@anthropic.com>
Use ParseHostID (consistent with all other callers) instead of inline SplitN. Skip NIC entries with empty MAC in GetHardwareNICs. Assisted-by: Claude Code <noreply@anthropic.com>
Add V(1) structured logging to GetHardwareNICs for consistency with other Manager methods (CreateBMH, DeleteBMH, IsBMHReady). Add test coverage for the empty-MAC filtering behavior added in 17b320f.

WalkthroughThe change adds BareMetalHost NIC retrieval and connects it to BCM inventory. MAC addresses are lowercased, empty values are excluded, lookup errors are wrapped, and tests cover valid, missing, empty, and invalid inputs. ChangesHardware NIC inventory
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change can return NIC information for the wrong namespace and can panic when the required host manager is not configured; it also exposes internal hostnames in verbose logs. The namespace validation and nil-dependency handling should be fixed before merging.

Remove the host name from these log events.
name is the BareMetalHost host name. These V(1) events expose an internal hostname when verbose logging is enabled. Remove name from both events.
As per coding guidelines, “Do not log … internal hostnames.”

Validate the inventory namespace before the BMH lookup.
ParseHostID returns a namespace, but this method discards it. If the manager uses osac-baremetal, other-namespace/node001 returns NICs from osac-baremetal/node001. Reject a namespace that differs from c.bmhManager.Namespace(), or change the manager API to use the parsed namespace.

Return an error when bmhManager is nil.
NewBCMClient permits a nil bmhManager. A GetHostNICs call on that client panics at this dereference. Check c.bmhManager and return a configuration error before the lookup.

[medium] architectural-assumption
GetHostNICs parses the namespace from inventoryHostID via ParseHostID but discards it, using c.bmhManager pre-configured namespace instead. If a caller passes a host ID with a different namespace, the method would silently query the wrong Kubernetes namespace. Current callers are safe (FindFreeHost constructs IDs from c.bmhManager.Namespace()), but Metal3Client.GetHostNICs uses the parsed namespace directly, making this an inconsistency between backends.
Suggested fix: After ParseHostID, validate that the parsed namespace equals c.bmhManager.Namespace(). Return an error on mismatch.

[low] edge-case
GetHardwareNICs can return an empty non-nil slice when all NICs in HardwareDetails have empty MAC addresses. The caller in BCMClient.GetHostNICs handles this correctly via len(macs) == 0, so there is no functional bug, but the log reports Retrieved hardware NICs with count=0 rather than has no hardware NIC data, which may confuse debugging.
Suggested fix: Add a len(macs) == 0 check after the loop to return nil consistently with the no-data path.

[low] documentation-accuracy
The function comment states Returns nil when the BMH has no hardware details or no NICs recorded but does not account for the case where NICs are present but all contain empty MAC addresses (returns empty slice, not nil).
