Let me be clear, please don't do this. I really dislike that we need
audit_alloc_local(), but we do because computers are awful things and
audit is perhaps even more awful.
Computers *are* awful, and getting awfuller. Audit is awful beyond
comprehension because the people who wrote the audit section of the
Orange Book didn't talk to the people who wrote the access control section,
and neither talked with anyone who hadn't worked on MULTICS. I wrote three
UNIX audit systems, helped out on several others and derailed the POSIX
effort completely. I have tried to avoid understanding Linux audit so far,
but have finally gotten to the point where I have to know something about
it. It's far from the worst I've seen. There are aspects I find peculiar,
but I have my (rather firm and old fashioned) notions.
Someday I'll make my peace with audit_alloc_local(), and/or it
will
become something more useful through consolidation, but now is not the
time to push on this issue considering where the audit container ID
patchset is at.
And now I'm coming in with a similar notion for stacking. Thanks for
your forbearance. We know there's lots on your plate, and that we're
coming at you from all directions.
