The bpf_ksock_send() kfunc eventually calls security_socket_sendmsg(), thus creating a possible recursion if a program calling the kfunc is attached on that specific hook. A filter is added on the kfunc registration to prevent that at load time from the verifier. This test exercises that the verifier will reject such program on that attach point.
