Openstack + ovs 1.4.6-0ubuntu1.12.04.4 + kernel 3.2.0-70 and newer crash on first gre traffic

Openstack + ovs 1.4.6-0ubuntu1.12.04.4 + kernel 3.2.0-70 and newer crash on first gre traffic

[Impact]

 * Openstack + ovs 1.4.6-0ubuntu1.12.04.4 + kernel 3.2.0-70 and newer crash on first gre traffic
 * Kernels newer than 3.2.0-70 are not able to be used with the openvswitch module built using 1.4.6-0ubuntu1.12.04.4

[Test Case]

 1. Deploy grizzly openstack with Openvswitch for neutron.
 2. Upgrade kernel on compute host to greater than 3.2.0-69
 3. Deploy and boot VM.
 4. Associate IP with VM
 5. Ping VM
 6. Watch compute host crash.

[Regression Potential]

 * Few character change
 * This has been broken since release of 3.2.0-70
 * Users should have already migrated Openstack clouds off of Grizzle + precise.

[Other Info]

 * 3.13 kernel ships with ovs module included in the kernel.

I'm working on a patch and will upload as soon as it's tested.

Here is the fix to this issue. Just needed to fix some arguments to ip_select_ident.

This was tested against 3.2.0-70 and 3.2.0-86 kernels.
