Hi The NETLINK_ROUTE family deifned as a part of the netlink socket protocol has the data handler of the sock structure set to rtnetlinl_rcv. However this function dequeues the data packet ( in the skb ) from the receive queue of the sock structure and processes it if the flag in the nlmsghdr is set ot NLM_F_REQUEST. While sending information back to the user this flag is not set. So the packet is dequeued and lost . Arnt there provisions made to handle packets from the kernel to the user ?
