hi all gys:
when I make LKM with netfilter on "NF_IP_PRE_ROUTING" point, but it
was reported that "NF_IP_PRE_ROUTING" is not defined.
but I am surely including <linux/netfilter_ipv4.h>, when I opened
include/linux/netfilter_ipv4.h I found that
"NF_IP_PRE_ROUTING" is in this lable :
#ifndef __KERNEL__
.....
/* IP Hooks */
/* After promisc drops, checksum checks. */
#define NF_IP_PRE_ROUTING 0
/* If the packet is destined for this box. */
#define NF_IP_LOCAL_IN 1
/* If the packet is destined for another interface. */
#define NF_IP_FORWARD 2
/* Packets coming from a local process. */
#define NF_IP_LOCAL_OUT 3
/* Packets about to hit the wire. */
#define NF_IP_POST_ROUTING 4
#define NF_IP_NUMHOOKS 5
#endif /* ! __KERNEL__ */
So I think the "endif" is ended a little early!
