- parse IPv6 header by using common function, ip6_{last,next}hdr.
- fix behaivior in multiple AH cases.
make strict boundary checks on mbuf chasing.
(sync with latest kame)
of IPv4 transport layer code work correctly (specifically, ICMPv4
will transmit wrong packet if we don't strip AH here)
this is just for m_pulldown case. normal installations are not affected.
pfil information, instead, struct protosw now contains a structure
which caontains list heads, etc. The per-protosw pfil struct is passed
to pfil_hook_get(), along with an in/out flag to get the head of the
relevant filter list. This has been done for only IPv4 and IPv6, at
present, with these patches only enabling filtering for IPPROTO_IP and
IPPROTO_IPV6, although it is possible to have tcp/udp, etc, dedicated
filters now also. The ipfilter code has been updated to only filter
IPv4 packets - next major release of ipfilter is required for ipv6.
- interop issues in ipcomp is fixed
- padding type (after ESP) is configurable
- key database memory management (need more fixes)
- policy specification is revisited
XXX m->m_pkthdr.rcvif is still overloaded - hope to fix it soon
