on each of them, and don't bother listening on them. this allows messages
to be forwarded even with -s enabled.
XXX: not 100% sure if this is susceptable to a DoS, e.g someone filling
up kernel buffers with a backlog of packets not being read, but shutdown(2)
should prevent that even if it possibly doesn't at this time.

the change constitutes binary compatibility issue hen sizeof(long) !=4.
there's no way to be backward compatible, and only guys affected
are IPv6 userland tools.

try all the set of addresses before go to sleep() and retry.
not sure if we still need sleep() - retry logic. why is it so persistent
in connecting?
From: SHIMIZU Ryo <ryo@misakimix.org>
draft-ietf-ipngwg-scopedaddr-format-00.txt (will be 01),
use "address%interface" notation for extended scoped IPv6 address.
NOTE: the change affects link-local addresses only. I hope it to be
the final change on it.....
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.
the hack tries to respect ifa or ifp passed to RTM_ADD. However, the change
broke certain link-layers. They include:
- midway ethernet card (en*), which uses sockaddr_dl in gateway portion
to pass PVC information. with the patch, the gateway portion will be
overwritten by empty sockaddr_dl and PVC initialization will fail.
- IPv6, which can't set static ND table with the patch (ndp -s), for the
similar reason as above.
There may be improved hack coming soon, hope the new one does not break others.
Continue partial write(2) on signals (xwrite()).
Partial read(2) at a few places are also continued (xread()).
Add {read,write}_with_restart() hooks for porting on systems
which don't restart interrupted read()/write() calls.
Reviewed and discussed in tech-kern and tech-userlevel lists.
- there's no match against addresses on IFF_UP interface,
send icmp unreach if I'm router. drop it if I'm host.
