Hi Joe,
adding a specific function here is not very suitable.
I have already proposed such a patch by adding my own hooks, then I
moved to the LSM hooks
http://www.mail-archive.com/netdev@vger.kernel.org/msg33814.html

I have rewrite the projet to directly use netlink socket (in fact
generic netlink socket) and move to a new protocol between userspace and
kernel
you can find patch here :
