From 471599dc7721d454b6658062c901b52038a78be2 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Mon, 20 Feb 2023 14:08:49 +0000 Subject: [efi] Split out EFI_RNG_PROTOCOL as a separate entropy source Commit 7ca801d ("[efi] Use the EFI_RNG_PROTOCOL as an entropy source if available") added EFI_RNG_PROTOCOL as an alternative entropy source via an ad-hoc mechanism specific to efi_entropy.c. Split out EFI_RNG_PROTOCOL to a separate entropy source, and allow the entropy core to handle the selection of RDRAND, EFI_RNG_PROTOCOL, or timer ticks as the active source. The fault detection logic added in commit a87537d ("[efi] Detect and disable seriously broken EFI_RNG_PROTOCOL implementations") may be removed completely, since the failure will already be detected by the generic ANS X9.82-mandated repetition count test and will now be handled gracefully by the entropy core.
