** Description changed: [Impact] Openvswitch DKMS module is not compatible with the 3.5 kernel which will be provided from 12.04.2. Users of openvswitch will only be able to use the native kernel module which does not support all features including GRE tunnelling. Openstack Quantum, for example, makes extensive use of this feature. [Test Case] Install 12.04.2 from ISO sudo apt-get install openvswitch-datapath-dkms DKMS module fails to build [Regression Potential] The cherry picked fixes provide support for the 3.5 kernel and rename the DKMS built modules to remove the _mod suffix. - This could regress the dkms package for 3.2 kernel users. + This could regress the dkms package for 3.2 kernel users (that said I + have tested this scenario and the upgrade from 3.2->3.5 as well). [Original Bug Report] The openvswitch-datapath-dkms module FTBFS with the 3.5 kernel proposed for 12.04.2: DKMS make.log for openvswitch-1.4.0 for kernel 3.5.0-23-generic (x86_64) Tue Feb 5 15:45:41 GMT 2013 checking build number... none checking for a BSD-compatible install... /usr/bin/install -c checking whether build environment is sane... yes checking for a thread-safe mkdir -p... /bin/mkdir -p checking for gawk... no checking for mawk... mawk checking whether make sets $(MAKE)... yes checking for gcc... gcc checking whether the C compiler works... no configure: error: in `/var/lib/dkms/openvswitch/1.4.0/build': configure: error: C compiler cannot create executables See `config.log' for more details make: Entering directory `/var/lib/dkms/openvswitch/1.4.0/build/datapath/linux' make: *** No targets specified and no makefile found.

The patches currently held for quantal should suffice to fix this problem.
