Subject: ipv6 address comparison
Date: Sat, 21 Jul 2012 18:02:41 +0600 [thread overview]
Message-ID: <1342872161.3431.13.camel@localhost> (raw)
Hi,
My module uses ipv6_addr_cmp() from <linux/ipv6.h>.
<linux/ipv6.h>
static inline int ipv6_addr_cmp(const struct in6_addr *a1, const struct
in6_addr *a2)
{
return memcmp(a1, a2, sizeof(struct in6_addr));
}
I've included <linux/ipv6.h>. But when i try to build the module i get
following error:
net/netfilter/xt_ipaddr.c:81: error: implicit declaration of function
?ipv6_addr_cmp?
Although before the call to ipv6_addr_cmp, i have a casting to struct
ipv6hdr *iph. So the definitions from ipv6.h should be available to my
module.
cheers.
aft
