[sig-node] [Exception Request] Code Freeze Exception request for KEP-6063: Per-Pod PID Limit

[Bhargavi Gudi]

Hi,

I would like to request a 4 calendar day code freeze exception for the following enhancement.

Details are as follows:

Enhancement name:Per-Pod PID Limit

Enhancement status:alpha
SIG:sig-node
k/enhancements repo issue #: https://github.com/kubernetes/enhancements/issues/6063 
PR #'s: https://github.com/kubernetes/kubernetes/pull/139277 

Additional time needed (in calendar days, due end of day AoE): 4 calendar days

Reason this enhancement is critical for this milestone: Per-pod PID limits allow workload authors to set a single PID limit shared by all containers in a pod, improving workload isolation. The implementation is complete; the PR has passed all unit tests and e2e node tests. It is in active API review with sig-node and API reviewers, and most review comments are resolved.

Risks from adding code late:Low — the feature is gated behind `PerPodPIDLimit` (Alpha, disabled by default), so it has zero impact on existing behavior. It is self-contained and does not modify any existing code paths when the gate is off.

Risks from cutting enhancement: Cutting this enhancement delays a feature that fills a key gap in pod-level resource management. Without per-pod PID limits, users must rely solely on node-level podPidsLimit, which applies uniformly to all pods and offers no workload-level granularity. Furthermore, the PR has undergone extensive API and sig-node review, and deferring would require re-review effort in the next cycle.

Thanks and regards,

Bhargavi Gudi
