.. 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.
