Then why does netlink_sendmsg() need to save the effective capability
set of the sender in the control buffer (via security_netlink_send) for
later checking by other receive functions in the kernel (via
security_netlink_recv)?  What prevents audit_receive() or other similar
receive functions in the kernel from processing messages sent by
multiple senders?
