Well, I suppose anything worth doing is going to be hard :)

The end-to-end design for this is the same end-to-end design that exists
for signing kernel modules today. We envisioned it working for others

We've heard your concerns about kern_sys_bpf and we agree that the LSM
should not be calling it. The proposal in this email should meet both of
our needs
