net: sched: add em_ipt ematch for calling xtables matches
The commit a new tc ematch for using netfilter xtable matches. This allows early classification as well as mirroning/redirecting traffic based on logic implemented in netfilter extensions. Current supported use case is classification based on the incoming IPSec state used during decpsulation using the 'policy' iptables extension (xt_policy). The module dynamically fetches the netfilter match module and calls it using a fake xt_action_param structure based on validated userspace provided parameters. As the xt_policy match does not access skb->data, no skb modifications are needed on match. Signed-off-by: Eyal Birger <eyal.birger@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
