to mention here. notable changes are like below.
kernel:
- make PF_KEY kernel interface more robust against broken input stream.
it includes complete internal structure change in sys/netkey/key.c.
- remove non-RFC compliant change in PF_KEY API, in particular,
in struct sadb_msg. we cannot just change these standard structs.
sadb_x_sa2 is introduced instead.
- remove prototypes for pfkey_xx functions from /usr/include/net/pfkeyv2.h.
these functions are not supplied in /usr/lib.
setkey(8):
- get/delete does not require "-m mode" (ignored with warning, if you
specify it)
- spddelete takes direction specification
add opt_awi.h to define AWI_DEBUG, AWI_WEP_ARC4.
show the firmware version at attach.
create a framework to support WEP (encryption code is not included for now).
a new wiconfig compatible ioctl interface replaced the awictl interface.
fix memory leak in selecting AP
fix bugs in ESSID selection

Fix a panic resulting from an obvious null pointer deref.
Apparently some other panics still exist in this driver, but with
this fix, it was at least possible to run the Nokia card at SANE 2000.
supposed to bubble carry through.
- Disable the double-loop version of ether_crc32_le() and add a
table-driven version of ether_crc32_le() -- the table-driven
version is faster.
the interface tries to negotiate ifid with the other end by using IPv6CP.
other changes:
- do not share ppp sequence number across protocols.
- if LCP proto-rej is received, drop the protocol mentioned by the message.
this is to be friendly with non-IPv6 peer (if the peer complains due to
lack of IPv6CP, drop IPv6CP). this basically implements "RXJ+" state
transition in the RFC.
- cleanup debugging message. always print blank just before message.
CAVEAT:
- if the peer uses the same MAC address as our side (pretty unlikely)
the code may go into req-rej loop.
- even though we negotiate ifid, we don't configure destination address
onto the interface. it is not really necessary to do so (IMHO).
- I've tested this code on a NetBSD 1.4.2 node, which was with fair amount
of modifications. not sure if the committed code does it right... (please
test and send reports)
to protocol handlers, based on src/dst (for ip proto #4/41).
see comment in ip_encap.c for details of the problem we have.
there are too many protocol specs for ip proto #4/41.
backward compatibility with MROUTING case is now provided in ip_encap.c.
fix ipip to work with gif (using ip_encap.c). sorry for breakage.
gif now uses ip_encap.c.
introduce stf pseudo interface (implements 6to4, another IPv6-over-IPv4 code
with ip proto #41).
- 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.
attached.
- Add ether_crc32_be() and ether_crc_le(), common functions for computing
the Ethernet CRC on arbitrary length buffers. Nothing uses them yet,
and these should be double-checked and probably re-implemented as
table-driven functions.
parties can easily know the state of a link.
- Define an interface announcement message for the routing socket so that
routing daemons and other interested parties know when an interface
is attached/detached.
