Hi there,
Hi,
I have a kernel module which asks for random numbers using
get_random_bytes().
Is there a way I can set this number generator my own seed value, so
that I can replay experiments I perform with my module? If I set a seed
for the whole system, it would affect other kernel tasks obtaining
random numbers through get_random_bytes(), so I guess that is not a
good solution.
Why don't you implement a simple PRNG in your own module that you can
control yourself for your experiments, and then replace it later with
get_random_bytes()?
There are a number of PRNG's that are simple to implement and good
enough for most problems:

I hope this helps,
