Isn't using perf_paranoid for this a disastrous choice?

AFAICT uprobe insertion is equivalent to root, since you can modify bytes in the middle of instructions, and thus alter the behavior of any process.

On the other hand, currently perf_paranoid only gives access to PMU, which can normally only be use to DoS the system at worst.
