Hi @mlguerrero12. Thanks for your PR.

I'm waiting for a openshift member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Maybe make a variable out of the config,move to line 25, and format it for better readability?

In BeforeEach, the tun module is loaded (if not already) but here it is not unloaded. Should it be?
I guess it depends if something else on the system is using it.

It is not loaded. The test always fails without it. I didn't unload it because it always complains that the module is in use even after removing the tap interface. So, I figured it is safe to leave it there.

It should not be that hard to implement.
The BeforEach DS should mount a dir on the node, and note whether the bool has been set:
sh -c 'getsebool container_use_devices > /host/tmp/initial_state

and the AfterEach DS would then revert the value only if the content of this file is 0.

+			"sh", "-c", "nsenter --mount=/proc/1/ns/mnt -- sh -c 'setsebool container_use_devices 0'",


This SELinux boolean may have been already set as a dependency of some service/app on the host. Blindly disabling it might have unintended consequences. Perhaps check if it's already set (in BeforeEach) and only disable it (in AfterEach) if it was not.

Test always fails without it. I know that it is a good practice to do what you're suggesting but I wonder if it is worth doing it in this case. No other tests modify selinux booleans.

I don't have a strong opinion here so either way is fine.

Will it be wrong to leave it on just to see if it collides with other services/apps? This way, we would be able to detect what cannot be run together with the tap plugin.

That's a good point.

done, let's see what we get

@cgoncalves, I decided to follow your suggestion. Please review again.
