For IPv6 it\nuses sizeof(struct ipv6hdr), while the surrounding IPVS code already\nparsed the packet with ip_vs_fill_iph_skb() and has the real\ntransport-header offset in iph.len.\n\nThis makes TCP state handling look at the wrong bytes when an IPv6\npacket carries extension headers. Use the parsed transport offset passed\ndown from ip_vs_set_state() when reading the TCP header.\n\nFor IPv4 and for IPv6 packets without extension headers, the passed\noffset matches the previous value."
