Just reflecting on the Linux RNG thread a bit ago, is there any
technical reason to have RNG in kernel space?
The procurement of an RNG source for crypto is always a *system* design
issue.
The expectation that a kernel offering (intended for a wide range of CPU
architectures, each of which being deployed in its own range of systems)
can solve this system issue is IMHO naive.
Thus, kernel space vs user space makes little difference.
This being said, the kernel developers appear to make good faith efforts
to adapt to the ever evolving digital electronics paradigms prevailing
in a few mainstream system architectures. Is this effective versus some
criteria for RNG quality? Is this good enough for you?
It's your duty to figure out, I guess.
