I cannot see any hole to iter the bpf_sk_storage_map and also bpf_sk_storage_get/delete() itself for now. I have looked at other iters (e.g. tcp, udp, and sock_map iter). It will be good if you can double check them also. I think at least one more test on the tcp iter is needed. Other than that, Acked-by: Martin KaFai Lau <kafai@xxxxxx>
