The patches look good to me. Phil, maybe get rid of that comment at the top which was worrying about endianness. I think you fixed it. Acked-by: Jamal Hadi Salim Your tests in patch 0 are nice and could go in tests/ directory. I can send you some of the basic tests i run via the kernel; they look something of the form: # #RFC #dst MAC starts at -14 #src MAC at -8 #ethertype at -2 # # tc filter add dev eth0 parent ffff: protocol ip prio 10 u32 \ match ip src 192.168.1.10/32 flowid 1:2 \ action pedit munge offset -14 u16 set 0x0000 \ munge offset -12 u32 set 0x00010100 \ munge offset -8 u32 set 0x0aaf0100 \ munge offset -4 u32 set 0x0008ec06 pipe \ action mirred egress redirect dev eth1 # # These would of course require more of a larger setup to vet and running tcpdump to check the correct bytes are being modified. cheers, jamal
