itojun bb8d535cc5 use per-block cipher function + esp_cbc_{de,en}crypt. do not use
cbc-over-mbuf functions in sys/crypto.

the change should make it much easier to switch crypto function to
machine-dependent ones (like assembly code under sys/arch/i386/crypto?).
also it should be much easier to import AES algorithms.

XXX: it looks that past blowfish-cbc code was buggy.  i ran some test pattern,
and new blowfish-cbc code looks more correct.  there's no interoperability
between the old code (before the commit) and the new code (after the commit).

XXX: need serious interop tests before move it into 1.5 branch

itojun 6574aa66e8 inhibit error code from rtinit(). this happens when we try to assign
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)

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

itojun 4308599c5a disallow bind(2) with IPv4 mapped address for now. port number check is
insufficient at this moment and we can bind(2) two sockets listen on same

find inpcb chain from particular in6pcb chain (like finding tcbtable from tcb6)
