Hi, Romain

  Sorry for late reply, and thank you to split your patch.

  I applied your patches except
  o Nakamura-san's patch(which is already going to be applied in our tree)
  o makefile-gnu-source.diff(see below)
  o xfrm.c.diff(see below)

  The list below is my environment:

gcc:      version 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
autoconf: autoconf (GNU Autoconf) 2.61(Debian 2.61-4)
flex    : flex 2.5.33(Debian 2.5.33-11)

  I don't use byacc. It may be the difference.

  When I applied this patch, mip6d always fails to send the first BU
  for the home registration.

  After I stopped mip6d and run again, home registration succeeds normally.

  The log is the following:
--------------------------------------------------
Thu Jul 12 04:09:38 mh_send: sendmsg: Operation not permitted
Thu Jul 12 04:09:38 mn_send_bu_msg: mh_send failed  ret: -1
--------------------------------------------------

  As long as I see, the policy to send BU to the HA is not inserted.
  I'm investigation the reason, and did you see the same problem?
