Subject: [FIX NETLINK] properly check arguments to netlink_bind()

Hi,

while going through going netlink code I found out that netlink_bind()
does not properly check bind parameters.  I checked both 2.6.23-rc1 as
well as 2.6.16.53, both are affected.

With a small test prog I wasn't able to crash my maschine though, but
data was accessed out of bounds.

Please apply the attached patch.

Thanks.
