[dm-crypt] Fuzzing

Hi,

I just stumbled upon those slides, where they test file system code in
the linux kernel (ext4, btrfs, xfs, ...) using a fuzzing method (they do
find bugs):

http://events.linuxfoundation.org/sites/events/files/slides/AFL%20filesystem%20fuzzing%2C%20Vault%202016.pdf

I have not studied it in detail, but it looks like they used the open
source "American Fuzzy Lop" (afl, written for userland code) and got
some ideas how to employ it for kernel code.

Could this perhaps be used to test some parts of cryptsetup?

Best wishes,
Lars
