Kubernetes: Closing the Gaps Between Cache and Reality
A cluster of fixes this cycle targets stale-state bugs, where cached or delayed data caused kube-apiserver and kube-proxy to make wrong decisions under normal operation. Two admission policy PRs and a kube-proxy fix all address the same underlying risk: components acting on outdated information.

The core problem: policies resolve their parameter kind through cached API discovery, which can lag behind reality after a CRD is established or the apiserver restarts. Under a…
A similar pattern shows up in kube-proxy. PR 141371 from Kiarash Azarnia cleans up stale conntrack entries left behind after a UDP service is deleted. Because UDP is connectionless, one-way traffic like logging or stats can keep refreshing an old timeout entry, silently redirecting traffic to an IP that's since been…
Rounding out the infrastructure side, Robert Bost's PR 141359 preps the watch cache's internal store interface for lazy iteration over snapshots — foundational work for the cacher, with sixteen review comments suggesting it's getting careful scrutiny before landing.
