[$] A RDRAND followup

LWN.net - Pon, 02/26/2024 - 18:53
In a recent episode, "Pitchforks for RDSEED", we learned that there was some uncertainty around whether hardware-based random-number generators on x86 CPUs could fail. Since the consequences of failure in some situations (confidential-computing applications in particular) can be catastrophic, there was some concern about this prospect and what to do about it. Since then, the situation has come a bit more into focus, and there would appear to be an agreed-upon plan for changes to be made to the kernel.
