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

Well, you included <linux/ipv6.h>. Here, the implementation of ipv6_addr_cmp() is in <net/ipv6.h>. Regards, Tobi
