[upstream commit 5b31544] Commit 310846e introduced a cleanup of the kprobe table entry on unload, which introduced some issues because unload is using when disabling sensors (that might be re-enabled later). Previous pre and post-hooks are still useful for resources management on unload. The kprobe table entry is added on creation (not load) and then it must be cleaned up on deletion introducing the new sensor.Destroy() method. 'Destroy' expresses the idea that the sensor is not usable past this point and must be recreated to be loaded. Signed-off-by: Mahe Tardy <[email protected]>

[upstream commit 19babbb] This should make sure the regression #1489 doesn't appear anymore: disabling/enabling broke because we cleaned up the generic kprobe table on unloading, which should have been done only on destroying the probe. Signed-off-by: Mahe Tardy <[email protected]>
[upstream commit 0690282] The testutils Config.TetragonLib (or in the end ConfigDefault.TetragonLib) was never written to the actual option.Config.HubbleLib. We noticed it was done manually all over the place in tests so this commit adds it in TestSensorRun that runs in TestMain. Signed-off-by: Mahe Tardy <[email protected]>
