avoid use of macros to manipulate sockaddrs (hides error case too much).
correct IPv4 packet handling when ip option is present.
preparations for ipsec policy engine upgrades.
- use latest source address selection code - in6_src.c.
- correct frag header insertion.
- deep copy ip6 header portion in ip6_mloopback to avoid overwrite.
- do not bark when we forward packet to loopback.
- some cosmetics.
insufficient at this moment and we can bind(2) two sockets listen on same
port number.
for real fix, we need to check inpcb table with in6pcb. we can't
find inpcb chain from particular in6pcb chain (like finding tcbtable from tcb6)
luckily RFC2553 does not talk about bind(2) behavior for IPv4 mapped.
IPv4 mapped brings in too much complexities...
with "beyondscope" icmp6 support).
"options FAKE_LOOPBACK_IF" will honor scope on loopback outputs. rcvif will
be real interface, not the loopback, just like when multicast loopback.
(sync with kame)
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.
- parse IPv6 header by using common function, ip6_{last,next}hdr.
- fix behaivior in multiple AH cases.
make strict boundary checks on mbuf chasing.
(sync with latest kame)
it was a bit too strong, and forbids multiple addresses from
same prefix to be assigned.
now the behavior is the same as previous - memory leak on interface address
addition failure.
