Even if you are testing on BE the commit message should say that it fixes the length passed to the checksum code and was detected by sparse. ... > hdr->icmp6_cksum = csum_ipv6_magic(&iph->saddr, &iph->daddr, > - iph->payload_len, > + be16_to_cpu(iph->payload_len), > IPPROTO_ICMPV6, > - csum_partial((__u8 *)hdr, iph->payload_len, 0)); > + csum_partial((__u8 *)hdr, be16_to_cpu(iph->payload_len), 0)); Oh - that code is indented far too many times.
