code, from netbsd-current repository.
#ifdef'ed version is always available from ftp.kame.net.
XXX please do not make too many diff-unfriendly changes, we'll need to take
bunch of diffs on upgrade...
due to massive changes in KAME side.
- IPv6 output goes through nd6_output
- faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator
using heavily modified DNS servers
- per-interface statistics (required for IPv6 MIB)
- interface autoconfig is revisited
- udp input handling has a big change for mapped address support.
- introduce in4_cksum() for non-overwriting checksumming
- introduce m_pulldown()
- neighbor discovery cleanups/improvements
- netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland)
- IFA_STATS is fixed a bit (not tested)
- and more more more.
TODO:
- cleanup os-independency #ifdef
- avoid rcvif dual use (for IPsec) to help ifdetach
(sorry for jumbo commit, I can't separate this any more...)
- in in6_ifattach_getifid(), we can grab interface id source iff the source
is universally (worldwide) unique. ARCnet hardware address is of 8bit and
does not satisfy the condition.
(in6_ifattach_getifid() is for getting interface id usable for pseudo
interfaces like gif*)
- xx_to_eui64() should return EUI64 format, not IPv6 interface id format.
this may seem awkward so I wish to clean these things up.
- in nd6.c, change if clause into case clause to allow future addition
of IFT_xxx easier.
