In this post^[1], we’ll look at implementing a simple character device
driver as a kernel module in NetBSD. Once it is loaded, userspace
processes will be able to write an arbitrary byte string to the device,
and on every successive read expect a cryptographically-secure
pseudorandom permutation of the original byte string.
