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

Fri Dec 7 17:00:47 UTC 2018
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
