Hi , I am trying to use PF_PACKET socket along with filters applied on the socket through setsockopt, SO_ATTACH_FILTER. Now as I create this socket, any packet coming to the kernel would be copied into the socket buffer for this socket. So, even if I apply the filter, first few packets would always be those which do not match the filter. Is there a way (some socket option), to make socket passive and active, so that I will set the socket in passive mode after creation, and then set it as active, after I apply the filter, so that I only receive the filtered packet in user space.
