Hello Pablo,

Thanks a lot for your feedback.

This is the first of a set of patches that adds a netfilter module to parse
D-Bus messages, the complete patch-set is:

[PATCH 13/15] netfilter: nfdbus: Add D-bus message parsing
[PATCH 14/15] netfilter: nfdbus: Add D-bus match rule implementation
[PATCH 15/15] netfilter: add netfilter D-Bus module

patches 13 and 14 just include D-Bus helper code to be used by the netfilter
module (added on patch 15) and specially the dbus_filter netfilter hook function.

For the next post version we will reorganize the patches so first the D-Bus
netfilter module is added with an empty dbus_filter function and then added the
D-Bus helper code.

Also, we will move the nfdbus netfilter module to net/bus so is not inside the
netfilter core code.

Thanks a lot and best regards,
Javier
