Hi Aaron, Jakub, all,
I have recently been exercising the Open vSwitch kernel selftests, using vng, something like this:
TESTDIR="tools/testing/selftests/net/openvswitch"
vng -v --run . --user root --cpus 2 \ --overlay-rwdir "$PWD" -- \ "modprobe openvswitch && \ echo \"timeout=90\" >> \"${TESTDIR}/settings\" && \ make -C \"$TESTDIR\" run_tests"And I have some observations that I'd like to ask about.
Building the kernel using the following command does not build the openvswitch kernel module.
vng -v --build \ --config tools/testing/selftests/net/config
All that seems to be missing is CONFIG_OPENVSWITCH=m and I am wondering what the best way of resolving this is.
Perhaps I am doing something wrong. Or perhaps tools/testing/selftests/net/openvswitch/config should be created? If so, should it include (most of?) what is in tools/testing/selftests/net/config, or just CONFIG_OPENVSWITCH=m?
I noticed something similar when testing Jiri's virtio_net selftests patchset [1].
drivers/net/virtio_net/config includes virtio options but the test also needs at least CONFIG_NET_VRF=y which is part of net/config.
Whatever the answer to your question, all config files should be coherent on this matter.

- openvswitch.sh starts with "#!/bin/sh". But substitutions such as "${ns:0:1}0" fail if /bin/sh is dash. Perhaps we should change openvswitch.sh to use bash?
I think so. A similar change was done in c2518da8e6b0 selftests: bonding: Change script interpreter (v6.8-rc1)
