What I'm wondering is if we shouldn't be simply instrument *every* invocation, and set the trust to zero if we ever trip it.I guess you can add some logic to rdrand_long() to sanity-check what it returns... But would that be worth the effort?
I think doing it centrally, as non-arch-specific code, and letting it subsume ad hoc checks for known failure conditions could be a win. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
