IPVS uses this false assumption, and will write SNAT & DNAT modifications at a fixed pos which will corrupt the message. To fix this, proper header position must be found before modifying packets. Introducing ip_vs_fill_iph_skb(), which uses ipv6_find_hdr() to skip the exthdrs. It finds (1) the transport header offset, (2) the protocol, and (3) detects if the packet is a fragment. Note, that fragments in IPv6 is represented via an exthdr. Thus, this is detected while skipping through the exthdrs. This patch depends on commit 84018f55a: "netfilter: ip6_tables: add flags parameter to ipv6_find_hdr()" This also adds a dependency to ip6_tables. Originally based on patch from: Hans Schillstrom kABI notes: Changing struct ip_vs_iphdr is a potential minor kABI breaker, because external modules can be compiled with another version of this struct. This should not matter, as they would most-likely be using a compiled-in version of ip_vs_fill_iphdr(). When recompiled, they will notice ip_vs_fill_iphdr() no longer exists, and they have to used ip_vs_fill_iph_skb() instead.

IPVS do like conntrack i.e. use the skb->nfct_reasm (i.e. when all fragments is collected, nf_ct_frag6_output() starts a "re-play" of all fragments into the interrupted PREROUTING chain at prio -399 (NF_IP6_PRI_CONNTRACK_DEFRAG+1) with nfct_reasm pointing to the assembled packet.) Notice, module nf_defrag_ipv6 must be loaded for this to work. Report unhandled fragments, and recommend user to load nf_defrag_ipv6. To handle fw-mark for fragments. Add a new IPVS hook into prerouting chain at prio -99 (NF_IP6_PRI_NAT_DST+1) to catch fragments, and copy fw-mark info from the first packet with an upper layer header. IPv6 fragment handling should be the last thing on the IPVS IPv6 missing support list.

Finding the IPv6 headers is done as early as possible, and passed on as a pointer "struct ip_vs_iphdr *" to the affected functions. This patch reduce/removes 19 calls to ip_vs_fill_iph_skb().
