I decided to have a quick look, and this caught my eye: —- zx_cprng_draw() terminates the calling process if buffer is not a valid userspace pointer. ——

”Terminates the calling process”? That sounds different and interesting, do you know more about this aspect of Fuchsia?

I'm not too familiar with Fuchsia, but other syscalls return ZX_ERR_INVALID_ARGS so I suspect the idea was to keep this particular, security-critical call as simple as possible. This behavior shouldn't break any code that wasn't already broken.
