Current status:
Only OHCI chip is supported (fwohci).
ping (IPv4) works with Sony's implementation (SmartConnect) on Win98.
sometimes works but not stable.
Not implemented yet:
IRM (Isochronous Resource Manager) functionality.
Link layer fragmentation.
Topology map.
More to do:
clean ups
MCAP
charactor device part
dhcp
There is no entry in GENERIC config file yet.
Follow sys/dev/ieee1394/IMPLEMENTATION to enable if_fw.
- be persistent on initializing interfaces, even if there's manually-
assigned linklocal, multicast/whatever initialization is necessary.
- do not cache mac addr in the kernel. grab mac addr from existing cards
(this is important when you swap ethernet cards back and forth)
now ppp6 works just fine!
call in6_ifattach() on ATM PVC interface to assign link-local, using
hardware MAC address as seed.
(the change is in sync with kame tree).
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
it is not supposed to work.
logging fix: add "\n" to some of log() in in6_prefix.c.
improve in6_ifdetach(). now almost all structure depend on ifnet
will be cleared up.
possible loose ends:
- cached route_in6 in static varaiables needs to be cleared as well
- there are ifaddr manipulation without reference counting,
which should be fixed
we still see panics after card removal, though... not sure what is left.

kludge entries. the situation would occur if you take the following steps:
- join multicast groups (default ones like linklocal all-node is fine)
- remove all IPv6 addresses manually
- remove pcmcia card
to thorpej: pls call in6_ifdetach() when PRU_PURGEIF is raised (just before
removing ifnet). it should do the right thing (unable to perform real test
though)
when the last IPv6 address on an interface is get removed.
in6_ifattach() configures it and in6_ifdetach() removes it.
XXX last part of in6_purgeaddr looks very ugly, but there's no event for
"interface detach" (events are for "address detach").
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...)
- 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.
This situation happens on severe memory shortage. We may need more
improvements here and there.
- Grab IEEE802 address from IFT_ETHER card, even if the card is
inserted after bootup time. Is there any other card that can be
inserted afterwards? pcmcia fddi card? :-P
- RFC2373 u bit handling suggests that we SHOULD NOT copy interface id from
ethernet card to pseudo interface, when ethernet card has IEEE802/EUI64
with u bit != 0 (this means that IEEE802/EUI64 is not universally unique).
Do not use such address as, for example, interface id for gif interface.
(I have such an ethernet card myself)
This may change interface id for your gif interface. be careful upgrading
rc files.
(sync with recent KAME)
- do not perform IPv6 initialization for faith* interface, as they become
mistakingly IFF_UP. we are wondering if we should nuke in6_ifattach_p2p().
(sync with recent kame)
(Sorry for a big commit, I can't separate this into several pieces...)
Pls check sys/netinet6/TODO and sys/netinet6/IMPLEMENTATION for details.
- sys/kern: do not assume single mbuf, accept chained mbuf on passing
data from userland to kernel (or other way round).
- "midway" ATM card: ATM PVC pseudo device support, like those done in ALTQ
package (ftp://ftp.csl.sony.co.jp/pub/kjc/).
- sys/netinet/tcp*: IPv4/v6 dual stack tcp support.
- sys/netinet/{ip6,icmp6}.h, sys/net/pfkeyv2.h: IETF document assumes those
file to be there so we patch it up.
- sys/netinet: IPsec additions are here and there.
- sys/netinet6/*: most of IPv6 code sits here.
- sys/netkey: IPsec key management code
- dev/pci/pcidevs: regen
In my understanding no code here is subject to export control so it
should be safe.
