Works on all 4 tests i tried out on net-2.6[1]. GoodStuff Herbert. Herbert, please look at the comment i sent on the clone vs copy. Also, iirc this started as a netfilter optimization thing starting with tail-calls - can someone (Patrick?) clue me how it helps in that optimization aspect? cheers, jamal [1] Didnt try any ipt action, will when i get the chance again. Heres test 18b): --- Window1) tc qdisc del dev lo ingress Window1) tc qdisc add dev lo ingress Window1) ifconfig dummy0 up Window1) tcpdump -n -i lo -x -e -t & Window2) tcpdump -n -i dummy0 -x -e -t & Window1) tc filter add dev lo parent ffff: protocol ip prio 10 u32 \ match ip dst 127.0.0.1/32 flowid 1:2 \ action pedit munge offset 0 u32 clear pipe \ action mirred egress mirror dev dummy0 Window2) ping -c 1 127.0.0.1 Ping will fail since we are clearing first 4 byte of ip header. Window1 will show the packet as seen on incoming by lo; the first few bytes look like: ---- 4500 0054 0000 4000 4001 3ca7 7f00 0001 ---- Window2 will show the 4 bytes zeroed out as requested of pedit (and as seen on dummy0) --- 0000 0000 0000 4000 4001 3ca7 7f00 0001 --------- - 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
