skb_recv_datagram() Blocks

Question posted by: hnshashi (Newbie) on July 2nd, 2008 06:58 AM

Hi all,
I have written kernel module to communicates with user space appl. using netlink socket.

skb = skb_recv_datagram(nl_sk,0,1,&err); (Blocks at this point)
skb type is "struct sk_buff";
nl_sk type is "struct sock"

when calling skb_recv_datagram()(in kernel module) and choose it to be blocking (for a timeout period) it blocks and never wake up even if a packet has arrived to kernel,the packet has arrived from user space for sure .. cause the call back function i've registered while creating the socket is called every time i send a packet from user space.

Plz help me what is problem
