Hi I have a few doubts regarding netlink sockets. Does the NETLINK_ROUTE family allow communication between the user and the kernel in both directions ? If it does then where do the packets from the kernel get queued ? The data ready handler of the NETLINK_ROUTE family calls rtnetlink_rcv which dequeues the packet and processes it only if it the request flag is set. How are the packets from the kernel handled .. say when inet_rtm_getroute function is executed ( this function dosnt set the request flag ) ? Thanks in advance Regards Praveen Rajendran - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
