- manually configure an address from prefix P (like P::1)
- autoconfigure additional address from the same prefix P (like P::ifid).
- rtrequest fails due to P/plen already exists
more fundamental solution should appear later, when kame side stablizes it.
from thopej.
multiple addresses from same prefix, onto single interface. PR 10427.
more info:
- 4.4BSD did not check return code from in_ifinit() at all.
4.4BSD does not support multiple address from same prefix.
- past KAME change passed in{,6}_ifinit() to upwards, toward ifconfig(8).
the behavior is filed as PR 10427.
- the commit inhibits EEXIST from rtinit(), hence partially recovers old
4.4BSD behavior.
- the right thing to happen is to properly support multiple address assignment
from the same prefix. KAME tree has more extensive change, however, it needs
much more time to get stabilized (rtentry refcnt change can cause serious
issue, we really need to bake it before bring it to netbsd)

address/routing table too much).
in6_ifloop_request()
not to request rtrequest to return an rtentry except for the ADD
operation, in order to avoid misdecreasing the refcnt (which might
cause leak of rtentry)
- add protection mechanism against ND cache corruption due to bad NUD hints.
- more stats
- icmp6 pps limitation. TOOD: should implement ppsratecheck(9).
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.
