As far as I'm concerned, preventing root from crashing the system should not be a design goal of lockdown at all. And I think that the "integrity" mode should be as non-annoying as possible, so I think we should allow reading from debugfs.I have no horse in this game - I'm happy to bring back the previous approach for integrity mode and block reads entirely in confidentiality mode, but I'd rather not spend another release cycle arguing about it.
I really do not care either way about any of this :) greg k-h
