Package: linux-2.6
Version: 3.3.4-1~experimental.1
Severity: wishlist

Hi,
kernel 3.3 got mainline support for Open vSwitch (CONFIG_OPENVSWITCH /
openvswitch.ko) which was previously available as a DKMS module package. This
would make the module-assistant and DKMS packages openvswitch-datapath-source and
openvswitch-datapath-dkms obsolete.

Anyhow this module is required to get openvswitch running on Debian, where the
userspace utilities do already exist.

I don't think so. As I understand it, the in-tree version does not yet
have all the features of the out-of-tree version, and some features may
have to be implemented differently (more integrated with the rest of the
kernel).

Have you tried building the kernel with this option? Does the in-tree
module work properly with the existing utilities package?

I've tried to do so a few days ago using a 3.5 kernel pre-release with
the latest user-space utilities available in Debian. The vanilla kernel
module works fine with the supplied utilities and look feature complete
to me.

The utils do not work together with the vanilla kernel module out of the
box. That's because of naming confusions between the DKMS kernel module
and the upstream kernel module, however. This is a bug in the init
script of the package itself.


Having that said, the Debian DKMS package also provides a brcompat
module which replaces the Linux bridge module. That one is missing in
the upstream kernel entirely.
