The handler switches the skb->dev to the VRF device and sends it back for another pass. While this works fine a side effect is that it bypasses netfilter with the skb set to the original device. Looking at how to provide that feature a few options come to mind: 1. Have the rx handler in the VRF driver duplicate some of the processing of ip_rcv up to the NF_HOOK and then switch the skb->dev to vrf device. 2. Run NF_HOOK in ip_rcv twice -- once with orig_dev and then again for dev. 3. Introduce an L3 rx-handler that provides the option of hooking packets at L3 rather than the current backlog loop. This RFC looks at option 3. I wanted to get opinions on the approach versus other options.No way, this is not going to pass.
I'll drop this option. Thanks for the quick response. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
