Change in ...coreboot[master]: security/vboot: Do not check for RW partitions if not part of the image
by Werner Zeh (Code Review) 18 Nov '21

18 Nov '21

Werner Zeh has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/31662 Change subject: security/vboot: Do not check for RW partitions if not part of the image ...................................................................... security/vboot: Do not check for RW partitions if not part of the image In the setup where measured boot is used with read-only partition only there is no RW_A or RW_B partition in the flash. In this case it makes no sense to let VBOOT check for these partitions just to fail and then fall back to recovery mode. Instead set the flag VB2_CONTEXT_RECOVERY_MODE right away so that VBOOT starts in recovery mode any time. This kind of bypasses VBOOT logic but is still suitable to have a pure measured boot scheme enabled. In addition it avoids the first two reboots due to missing RW_A and RW_B.

Amol N Sukerkar has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/32148 Change subject: security/vboot: Added logic to authenticate firmware using VBOOT library version 2.1 ...................................................................... security/vboot: Added logic to authenticate firmware using VBOOT library version 2.1 This feature adds logic to authenticate Coreboot stages using VBOOT libraries version 2.1 Users of this feature will need to enable CONFIG_VBOOT_STAGE_VERIFICATION to enable the corresponding logic in Coreboot to authenticate the VBLOCK version 2.1 and the Coreboot stage hashes. TEST=Create a coreboot.rom image which has keyblock and VBLOCK with VBOOT version 2.1 structures. This is done by enabling CONFIG_VBOOT_STAGE_VERIFICATION.
