RDRAND has notoriously been broken many times over its lifespan. Add a smoketest to RDRAND, in order to better sniff out potential security concerns. Also add a proper CPUID test in order to support older CPUs which may not have it; it was previously being tested but then promptly ignored. Testing algorithm inspired by linux's arch/x86/kernel/cpu/rdrand.c :x86_init_rdrand() per commit 049f9ae9.. Many thanks to Jason Donenfeld for relicensing his linux RDRAND detection code to MIT and the public domain. >On Tue, Nov 22, 2022 at 2:21 PM Jason A.
