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
correct interface address addition when link-local is added (check if ifp
matches).
make diff to kame repository easier (breaks some KNF)
sync with kame.
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).
