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

[Thomas Huth]

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 from Yang Hongyang
(integration into that infrastructure was pretty easy, so thanks for
this great work!)
The dumping filter can be used like this for example:

 ppc64-softmmu/qemu-system-ppc64 -device virtio-net,netdev=mynet \
     -netdev user,id=mynet,tftp=/tmp/tftp,bootfile=zImage \
     -object filter-dump,id=f0,netdev=mynet,file=/tmp/dumpfile.dat

The patches have to be applied on top of the Jason's net branch
(since the netfilter patches have not been pulled into master yet).

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
