Florian Westphal ae68933422 netfilter: ip_tables: pass table pointer via nf_hook_ops ... iptable_x modules rely on 'struct net' to contain a pointer to the table that should be evaluated. In order to remove these pointers from struct net, pass them via the 'priv' pointer in a similar fashion as nf_tables passes the rule data. To do that, duplicate the nf_hook_info array passed in from the iptable_x modules, update the ops->priv pointers of the copy to refer to the table and then change the hookfn implementations to just pass the 'priv' argument to the traverser. After this patch, the xt_table pointers can already be removed from struct net. However, changes to struct net result in re-compile of the entire network stack, so do the removal after arptables and ip6tables have been converted as well.
