This patch allows bpf tcp iter to call bpf_(get|set)sockopt. To allow a specific bpf iter (tcp here) to call a set of helpers, get_func_proto function pointer is added to bpf_iter_reg. The bpf iter is a tracing prog which currently requires CAP_PERFMON or CAP_SYS_ADMIN, so this patch does not impose other capability checks for bpf_(get|set)sockopt.
