Routing in userspace

[Vincent Bernat <bernat_(_at_)_free_(_dot_)_fr>]

Hello !

I would like  to  develop in user   space a  special  kind of  routing
protocol.  I have looked   over route(4) but  I am  not sure that  the
kernel interface will allow me to do what I want.

In fact, I want to  decide myself where each packet  should be sent. I
do  not only want   to dynamically   add a  route  for   an inexistent
destination or  for a failed destination,  I  want that  my user space
routing daemon to be solicited for each packet.

Is it possible with the provided kernel interface ?
