- Images for cloud-controller-manager, kube-apiserver, kube-controller-manager, and kube-scheduler now contain a minimal /etc/nsswitch.conf and should respect /etc/hosts for lookups ([#69238](https://github.com/kubernetes/kubernetes/pull/69238), [@BenTheElder](https://github.com/BenTheElder))

### SIG Scheduling

- `kubelet` now allows pods to use the `net.ipv4.tcp_keepalive_time` sysctl by default
  and the minimal kernel version is 4.5; Pod Security Admission allows this sysctl
  in `v1.29+` versions of the baseline and restricted policies. ([#118846](https://github.com/kubernetes/kubernetes/pull/118846), [@cyclinder](https://github.com/cyclinder))

- Kubelet allows pods to use the `net.ipv4.ip_local_reserved_ports` sysctl by default and the minimal kernel version is 3.16; Pod Security admission allows this sysctl in v1.27+ versions of the baseline and restricted policies.
