Message-ID: <B97B134FACB2024DB45F524AB0A7B7F2063EB8C6@XMB-BGL-419.cisco.com> Date: Thu, 22 Mar 2012 08:52:53 +0530 From: "Prashant Batra (prbatra)" <prbatra@...co.com> To: <netdev@...r.kernel.org> Subject: Query regarding pf_packet sockets 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.
