** Description changed: - The openvswitch-datapath-dkms module FTBFS with the 3.5 kernel proposed - for 12.04.2: + [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. + + [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. Stop. make: Leaving directory `/var/lib/dkms/openvswitch/1.4.0/build/datapath/linux' Although the 3.5 kernel does provide a native openvswitch module, it does not support GRE tunnels which are used extensively by OpenStack Quantum. The patches currently held for quantal should suffice to fix this problem.
