Public bug reported: port's allowed_address_pairs allow different IP and MAC set for port.
The current ovsfw implementation has this issue for allowed_address_pairs with different MAC with VM's MAC: 1. Packets with allowed_address_pairs' MAC and IP (different MAC with VM's MAC) cannot come out from VM because the table=72 OpenFlow only check dl_src=VM-MAC in br-int. 2. Cannot ping from outside to VM's allowed_address_pairs' MAC and IP (different MAC with VM's MAC) because the table=0 OpenFlow only check dl_dst=VM-MAC. We need to allow the situation that address_pairs with different MAC with VM's MAC. Suggest change: 1. Do not check dl_src in table=72 because table=72 has checked dl_src for Egress 2. Add all allowed MACs in table=0 and table=73 for Ingress 3. Check dl_dst and nw_dst in table=81 like table=71 do 4. Do not check dl_dst in table=82 because this check has done in table=0 and table=73 ** Affects: neutron Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
