[Qemu-devel] [PATCH RFC 0/5] Network traffic dumping via netfilter |

The "-net dump" option only works with the "-net" option. So far, it
is not possible to dump network traffic with the "-netdev" option yet.
This patch series now fixes this ugliness by enabling dumping for the
netdev devices via the new netfilter infrastructure. It can be used
like this for example:
qemu-system-ppc64 -nographic -vga none -device virtio-net,netdev=mynet \
-netdev user,id=mynet,tftp=/tmp/tftp,bootfile=zImage -boot n \
-netfilter dump,id=f0,netdev=mynet,file=/tmp/filterdump.dat
This series is based on v8 of Yang Hongyang's netfilter patches
(i.e. these have to be applied before the dumping patches can be
used). Since these netfilter patches are not upstream yet and still
might change the API in future versions, I'm sending my patches as
"RFC" (but since the integration with the current netfilter patches
was pretty easy already, they should be ready as normal patches very
soon after the netfilter patches have been finalized).
Thomas Huth (5):
net/dump: Add support for receive_iov function
net/dump: Rework net-dump init functions
net/dump: Separate the NetClientState from the DumpState
net/dump: Provide the dumping facility as a net filter
net/dump: Add documentation
