    [IPV6] MIP6: Loadable module support for MIPv6. · 59fbb3a6
    Masahide NAKAMURA 提交于
    This patch makes MIPv6 loadable module named "mip6".
    
    Here is a modprobe.conf(5) example to load it automatically
    when user application uses XFRM state for MIPv6:
    
    alias xfrm-type-10-43 mip6
    alias xfrm-type-10-60 mip6
    
    Some MIPv6 feature is not included by this modular, however,
    it should not be affected to other features like either IPsec
    or IPv6 with and without the patch.
    We may discuss XFRM, MH (RAW socket) and ancillary data/sockopt
    separately for future work.
    
    Loadable features:
    * MH receiving check (to send ICMP error back)
    * RO header parsing and building (i.e. RH2 and HAO in DSTOPTS)
    * XFRM policy/state database handling for RO
    
    These are NOT covered as loadable:
    * Home Address flags and its rule on source address selection
    * XFRM sub policy (depends on its own kernel option)
    * XFRM functions to receive RO as IPv6 extension header
    * MH sending/receiving through raw socket if user application
      opens it (since raw socket allows to do so)
    * RH2 sending as ancillary data
    * RH2 operation with setsockopt(2)
