The classifier should cover the most common use case and will work without any special configuration. The principle of the classifier is to directly access the task_struct via get_current(). In order for this to work, classification requests from softirqs must be ignored. This is not a problem because the vast majority of packets in softirq context are not assigned to a task anyway. For this to work, a mechanism is needed to trace softirq context. This repost goes back to the method of relying on the number of nested bh disable calls for the sake of not adding too much complexity and the option to come up with something more reliable if actually needed.
