netfilter: ip6t_NPT: Fix adjustment calculation
Cast __wsum from/to __sum16 is wrong. Instead, apply appropriate conversion function: csum_unfold() or csum_fold(). [ The original patch has been modified to undo the final ~ that csum_fold returns. We only need to fold the 32-bit word that results from the checksum calculation into a 16-bit to ensure that the original subnet is restored appropriately. Spotted by Ulrich Weber. ] Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
