** Description changed: + [Impact] + Users of the openvswitch + openvswitch DKMS modules are broken after kernel upgrades without manual intervention. DKMS modules should be auto-rebuilt. + + [Test Case] + Install Ubuntu 12.04 (without any kernel updates) + sudo apt-get install openvswitch-datapath-dkms + sudo apt-get install openvswitch-switch + Upgrade to new 3.2 kernel update (or even the new 3.5 kernel for 12.04.2) + Reboot + sudo service openvswitch-switch start + (will fail as DKMS modules not found for new kernel) + + + [Regression Potential] + The fix for this is minimal (single line) and just impacts the auto-rebuild config for dkms. + + However its bundled with the 3.5 kernel compatibility fixes which also + remove the _mod suffix from the DKMS built modules. This has the effect + that if the DKMS modules are not built openvswitch will fall-back to the + less feature-full native openvswitch module provided by the kernel + itself (this is aligned to behavior in quantal and raring). + + + [Original Bug Report] Hello all, I've noticed that the openvswitch_mod and brcompat_mod modules are not automatically rebuild when I've upgraded to the latest linux- image-3.2.0-20-generic, thus rendering my openvswitch config unusable after a reboot to said new kernel. Manual rebuilding and installation worked as expected: ---------------cut--------- root@d02-spi-2:~# uname -a Linux d02-spi-2 3.2.0-20-generic #32-Ubuntu SMP Thu Mar 22 02:22:46 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux root@d02-spi-2:~# dpkg -l | egrep 'linux-(image|headers)' ii linux-headers-3.2.0-19 3.2.0-19.31 Header files related to Linux kernel version 3.2.0 ii linux-headers-3.2.0-19-generic 3.2.0-19.31 Linux kernel headers for version 3.2.0 on 64 bit x86 SMP ii linux-headers-3.2.0-20 3.2.0-20.32 Header files related to Linux kernel version 3.2.0 ii linux-headers-3.2.0-20-generic 3.2.0-20.32 Linux kernel headers for version 3.2.0 on 64 bit x86 SMP ii linux-headers-server 3.2.0.20.22 Linux kernel headers on Server Equipment. ii linux-image-3.2.0-19-generic 3.2.0-19.31 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-3.2.0-20-generic 3.2.0-20.32 Linux kernel image for version 3.2.0 on 64 bit x86 SMP ii linux-image-server 3.2.0.20.22 Linux kernel image on Server Equipment. root@d02-spi-2:~# dkms status -m openvswitch openvswitch, 1.4.0, 3.2.0-19-generic, x86_64: installed root@d02-spi-2:~# dkms build -m openvswitch -v 1.4.0 Kernel preparation unnecessary for this kernel.
