Can you develop your CUSE thing enough that it’s credibly safe against side channels? If so, fine.
I admit this is all rather absurd. FIPS aware userspace can do whatever it wants, and
It should be aware that /dev/urandom IS NOT FIPS. What’s the problem? rand(3) isn’t FIPS either, but no one puts person-years of effort into trying to paint it FIPS-colored
