* openvswitch: switch to depending on python3Mark Asselstine2017-06-211-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | As far as I can tell openvswitch has been updated to work with python3 as well as with python(2). Switch to depend on python3 and use python3 for associated scripts. For the most part openvswitch will bind at runtime to either py2 or py3 regardless of these changes, with these changes we just do a better job of setting up the dependencies to facilitate py3 bindings. The openvswitch autotests results are mostly identical before and after this switch (failures move from python3 to python(2) test cases as expected, with some exceptions see below). When running the autotests/ptest with python(2) vs python3 we see a slightly higher failure rate (334 failures vs. 284 failures). I do not believe this higher fail rate reflects actual errors in the runtime, rather the tests are not adapted to python3. At any rate like the rest of openvswitch it is fairly straightforward to hack the logic for autotests to be run using py2 as long as it is available in the image, so these changes don't prevent falling back to py2 for autotests. This should facilitate any debugging we need to do based on us switching to favor py3.

* openvswitch: uprev to the recently released v2.7.0Mark Asselstine2017-03-291-7/+106
| | | | | | | | | | | | | | | This version of OVS was released on Feb. 21. Bringing our recipe up to date with the latest release ensure we have all the latest CVE fixes as well as any new functionality that folks might be looking for. Additionally we are better situated to support up to date releases of DPDK (v16.11 in this case). No surprises with the uprev, it passes all usecase tests (meta-overc) and ptest results are much the same as the results we had in v2.6.1. While completing the uprev I took the opportunity to do some cleanup of patches that were no longer used or required.

* openvswitch: fix build host contaminationMark Asselstine2017-01-141-0/+53
There is only a single PYTHON variable for configure and yet python is used for the build as well as scripts installed on the target. If we set a path in PYTHON as we had we end up using this same path during the build and since it isn't to the sysroot we end up with host contamination (as demonstrated by python failing to import 'six' on build hosts without python-six installed. The best approach is to set PYTHON to "python" when calling configure, ie. without a path. This will use 'python' from the path during build time and by ensuring all the installed scripts use '/usr/bin/env' we can ensure python will be found on the target when the scripts are run. Since 'six' is used as part of the build we have to ensure it is -native'ly buildable and we set all the required build and runtime dependencies.
