fix(device): acquire node lock for initContainer device requests#2796AyushSrivastava1818 wants to merge 3 commits into
Conversation
Device backends' LockNode and ReleaseNodeLock previously only inspected pod.Spec.Containers when determining whether to acquire or release node locks. When a pod requested device resources solely in pod.Spec.InitContainers, HAMi allocated devices during admission and Filter/scoring, but LockNode returned nil without locking the node, allowing concurrent device allocation races. Update LockNode and ReleaseNodeLock in all affected device backends (NVIDIA, Ascend, AMD, Hygon, Cambricon, Kunlun vDevice, Metax SDevice, VastAI, Biren, and Iluvatar) to scan both pod.Spec.InitContainers and pod.Spec.Containers.

A redundant TestReleaseNodeLock function was introduced without initContainer coverage cases. The comprehensive declaration at line 2334 (containing container-only, initContainer-only, and both-containers test cases) is the canonical one. Remove the redundant definition to fix the golangci-lint duplicate-declaration error. Signed-off-by: AyushSrivastava1818 <ayush.sri0705@gmail.com>

Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The PR extends node locking to initContainer-only device requests, but the current head still has a Cambricon lock-annotation correctness issue and regression tests that may not prove the lock lifecycle.

@AyushSrivastava1818 the same loop is copy pasted multiple times. Please move it into a single helper in pkg/device or a suitable file. which will check InitContainers then Containers and you can call that from each LockNode/ReleaseNodeLock.

Appreciate the review...will move it into a single helper soon

this block is copied in all 10 device files, same code twice per file. can this move to one shared helper function instead? less risk of copy paste bugs later.

superseded by #2755, which moved the init container check into the shared PodRequiresDevice helper and removed the per backend loops this PR edits. thanks for the work here. |

/kind bug
What does this PR do / why do we need it?
HAMi's device resource accounting supports device requests in both
initContainersand regularcontainers, but the node-locking logic in several device backends only inspectedpod.Spec.Containers.As a result, a pod requesting device resources exclusively through an
initContainercould reach the scheduling/bind path without acquiring the corresponding node lock.This could allow concurrent scheduling operations on the same node to proceed without the expected node-level mutual exclusion, potentially causing device allocation or node annotation races.
This PR updates the affected device backends so that node-lock detection consistently considers both
InitContainersand regularContainers.Changes
LockNode()to inspectpod.Spec.InitContainersin addition topod.Spec.Containers.ReleaseNodeLock()to use the same detection logic.LockNode()implementations unchanged.Expected behavior
Regression Tests
Added coverage for the affected backends covering:
initContainersonly.initContainersand regular containers.LockNode()andReleaseNodeLock()behavior.Validation
go test -count=1 ./pkg/device/...— passedgolangci-lintv2.12.2 — passed with 0 issuesgofmt -s -w— passedgit diff --check— passedUser-facing impact
Pods that request HAMi-managed device resources exclusively through
initContainerswill now correctly participate in the device backend's node-locking mechanism.Existing behavior for regular-container device requests is preserved.
AI Assistance Disclosure
AI assistance from Claude and Antigravity was used for codebase investigation, identifying and tracing the initContainer node-locking gap, implementation assistance, test development, and review of the affected logic.
The final implementation was manually reviewed, and the relevant unit tests, formatting checks,
git diff --check, and repository-configuredgolangci-lintvalidation were performed to verify the changes.Related Issue
