- manually configure an address from prefix P (like P::1)
- autoconfigure additional address from the same prefix P (like P::ifid).
- rtrequest fails due to P/plen already exists
more fundamental solution should appear later, when kame side stablizes it.
from thopej.
- remove net.inet6.ip6.nd6_proxyall. introduce proxy NDP code works
just like "arp -s".
- revise source address selection.
be more careful about use of yet-to-be-valid addresses as source.
- as router, transmit ICMP6_DST_UNREACH_BEYONDSCOPE against out-of-scope
packet forwarding attempt.
- path MTU discovery takes care of routing header properly.
- be more strict about mbuf chain parsing.
although this version has been changed somewhat:
- reference counting on ifaddrs isn't as complete as Bill's original
work was. This is hard to get right, and we should attack one
protocol at a time.
- This doesn't do reference counting or dynamic allocation of ifnets yet.
- This version introduces a new PRU -- PRU_PURGEADDR, which is used to
purge an ifaddr from a protocol. The old method Bill used didn't work
on all protocols, and it only worked on some because it was Very Lucky.
This mostly works ... i.e. works for my USB Ethernet, except for a dangling
ifaddr reference left by the IPv6 code; have not yet tracked this down.
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...)
