    OK, I'm about to send a new patch; but while testing my patches and reading code, I noticed another bug :

    In smackfs.c:smk_write_netlbladdr
    the netmask mask.s_addr is not handled correctly, the netmask should be :
    1- computed in u32
    2- converted to be32 !!
    with current code, a "pseudo u32 mask" is applied to a be32 ipaddr; it occurs to works for "common netmasks" (multiple of 8), not for "intermediate" mask (/15, /25)

    OK, I tested some code in userspace and when i was confident enough coded it to kernel

    OK :)
