Also, cgroup v1 controllers net_cls and net_prio have to be disabled, or cgroup v1 has to be (e.g. by setting the kernel cgroup_no_v1="all" parameter). This ensures that Kind nodes have their own cgroup namespace, and Cilium can attach BPF programs at the right cgroup hierarchy. To verify this, sudo ls -al /proc/$(docker inspect -f '{{.State.Pid}}' kind- control-plane)/ns/cgroup $ sudo ls -al /proc/self/ns/cgroup See the Pull Request [https://github.com/cilium/cilium/pull/16259] for more details

Validate the overlapping BPF cgroup type programs attached to the parent cgroup hierarchy of the kind container nodes. In such cases, either tear down Cilium, or manually detach the overlapping BPF cgroup programs running running in the parent cgroup hierarchy by following the bpftool documentation [https://manpages.ubuntu.com/manpages/focal/man8/bpftool-cgroup.8.html].
