[IPSET] help with netlink connector

[vl4d]

I'm trying to rewrite the ipset sockopt interface with netlink connector 
introduced in 2.6.14... anyway i need some help and directions.

As far as i have understood ipset adds SO_ IP_SET option to IP and manage the 
whole stuff through {set|get}sockopt. How can i access this option using 
connector? do i have to register a connector callback at kernel level  using 
a module and send messages from ipset ??

i need disperate help :D

Regards

That'd mean a complete rewriting of the kernel-userspace communication in
ipset. You would not want to access the (set|get)sockopt from netlink but
replace it with a netlink communication channel. Instead of netlink, the
netfilter specific nfnetlink is the proper tool for such a rewriting.
(The subject is on the TODO list of ipset.)

As far as I see, both the newest connector and nfnetlink are just
instances of netlink. But because netfilter are going to use nfnetlink,
ipset should use the same.

...wait, do you mean nfnetlink instead of the newest connector?
