brcompat module problem after upgrade to the release "1.4.0-1ubuntu1.4".

Asked by Thiago Martins

Hi!

 I was running Open vSwitch 1.4.0 on my Ubuntu 12.04.2 LTS until the last upgrade, to the release (1ubuntu1.4).

 I mean, I just upgrade my Ubuntu 12.04.2 Open vSwitch packages (to 1.4.0-1ubuntu1.4) (aptitude update ; aptitude safe-upgrade ; reboot) and, the brcompat module isn't working anymore...

 My previous kernel.log.1 shows:

  "brcompat_mod: Open vSwtich Bridge Compatibility, build Jan 30...."

 But now, kernel.org (dmesg) shows:

  "brcompat: module license 'unspecified' taints kernel."

 Also, when I run:

   /etc/init.d/openvswitch restart

 I'm getting:

  "ovs-brcompatd: could not open brcompat socket. Check "brcompat" kernel module."

 I already tried to recompile the modules with: "dpkg-reconfigure openvswitch-datapath-dkms", the module is in fact, loaded but, doesn't work anymore... The command: "ifup br100" also doesn't work too...

 The initramdisk was updated with: "update-initramfs -u"

 And, the command: "ovs-vsctl show" seems to be working, "brctl show" also lists the bridge br100' there...

 Kernel version: 3.2.0-37-virtual

 Any clue?

Thanks!
Thiago

Upgrading to Open vSwtich 1.6.90-1.ubuntu.1 via:

sudo add-apt-repository ppa:gdahlman/openvswitch
sudo aptitude update
sudo aptitude safe-upgrade
sudo reboot

...solve my problem...

But, version 1.6.90 breaks something else, my nova-network (Openstack Folsom via Ubuntu Cloud Archive) doesn't work anymore, Instances doesn't come up.

I'll try to downgrade openvswitch to 1.4.0-1ubuntu1.3 (by disabling proposed updates)...

Back to: openvswitch 1.4.0-1ubuntu1.3, everything is fine...
ubuntu-proposed updates repository disabled for instance.
I'll try to reproduce this problem on a isolated VM.

Just for future reference any problems with packages in proposed should be reported back to the bugs identified in the changelog entires; this will stop them progressing to updates!

Can you help with this problem?
