Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

net/ipv6/netfilter/nf_nat_l3proto_ipv6.c: In function 'nf_nat_ipv6_csum_recalc':
net/ipv6/netfilter/nf_nat_l3proto_ipv6.c:144:4: error: implicit declaration of function 'csum_ipv6_magic' [-Werror=implicit-function-declaration]

Caused by commit 58a317f1061c ("netfilter: ipv6: add IPv6 NAT support").

(I always thought IPv6 NAT was a bad idea ;-))

I have applied the following patch for today:

From: Stephen Rothwell <sfr@canb.auug.org.au>
Date: Wed, 5 Sep 2012 15:34:58 +1000
Subject: [PATCH] netfilter: ipv6: using csum_ipv6_magic requires
 net/ip6_checksum.h

Fixes this build error:

net/ipv6/netfilter/nf_nat_l3proto_ipv6.c: In function 'nf_nat_ipv6_csum_recalc':
net/ipv6/netfilter/nf_nat_l3proto_ipv6.c:144:4: error: implicit declaration of function 'csum_ipv6_magic' [-Werror=implicit-function-declaration]
