[libvirt] [PATCH 1/2] util: add support for creating per-network chains



Rather than putting all rules into libvirt's main private chains, create
a private chain per network. This will make it easier for administrators
to use hooks to customize the chains per network.

For the LIBVIRT_INP, LIBVIRT_OUT, LIBVIRT_FWO and LIBVIRT_FWI chains
it is also possible to set interface name matches on the jumps to the
per-network chains. This will result in fewer iptables rules being
evaluated per packet when lots of networks are running.

We thus end up with the following chains

        INPUT --> LIBVIRT_INP +-> LIBVIRT_INP_virbr0   (filter)
                              +-> LIBVIRT_INP_virbr1
                              |  ...
                              \-> LIBVIRT_INP_virbrN

       OUTPUT --> LIBVIRT_OUT +-> LIBVIRT_OUT_virbr0   (filter)
                              +-> LIBVIRT_INP_virbr1
                              |  ...
                              \-> LIBVIRT_INP_virbrN

      FORWARD +-> LIBVIRT_FWX +-> LIBVIRT_FWX_virbr0   (filter)
              |               +-> LIBVIRT_INP_virbr1
              |               |  ...
              |               \-> LIBVIRT_INP_virbrN
              |
              +-> LIBVIRT_FWO +-> LIBVIRT_FWO_virbr0   (filter)
              |               +-> LIBVIRT_INP_virbr1
              |               |  ...
              |               \-> LIBVIRT_INP_virbrN
              |
              \-> LIBVIRT_FWI +-> LIBVIRT_FWI_virbr0   (filter)
                              +-> LIBVIRT_INP_virbr1
                              |  ...
                              \-> LIBVIRT_INP_virbrN

  POSTROUTING --> LIBVIRT_PRT +-> LIBVIRT_PRT_virbr0   (nat & mangle)
                              +-> LIBVIRT_INP_virbr1
                              |   ...
                              \-> LIBVIRT_INP_virbrN
