Hi,

	In this patch, these three fixes were made in net/ipv4/netfilter/ip_queue.c:
	
	1) No need to perform data_len = 0 in the switch command, since data_len
	   is initialized to 0 in the beginning of the method
,ipq_build_packet_message().
		
	2) We can reach nlmsg_failure only from one place; skb is sure to be NULL
	   when getting there; since skb is NULL, there is no need to check this fact
	   and call kfree_skb().
	
	3) Add #ifdef CONFIG_PROC_FS when removing the VFS entry,
 		 proc_net_remove(&init_net, IPQ_PROC_FS_NAME);
	

Regards,
Rami Rosen
