.. And how the f*^& did you imagine that something like chrome would do that?

You need massive amounts of privileges, and it's a total disaster in
every single respect.

Stop pushing crap. No, ptrace isn't wonderful, but your LSM+auditing
idea is a billion times worse in all respects.

We can definitely fix the ptrace issue with compat system calls.

THERE IS NO WAY IN HELL YOU CAN EVER FIX LSM+AUDIT TO BE USABLE!

Stop bothering to even bring it up. It's dead, Jim.
