From 1058dd84f06fa2fcbdd99eb99da07dccdf5b9722 Mon Sep 17 00:00:00 2001 From: Wim Vervoorn Date: Fri, 1 Nov 2019 10:22:22 +0100 Subject: security/vboot: Removed vboot_prepare from vboot_locator When prog_locate() is called in the stage VBOOT is starting from and the image to be loaded is not the target image vboot_prepare() may be called too early. To prevent this vboot_prepare() is removed from the vboot_locator structure. This allows more control over the start of the vboot logic. To clarify the change the vboot_prepare() has been renamed to vboot_run_logic() and calls to initialize vboot have been added at the following places: postcar_loader: when VBOOT starts in ROMSTAGE romstage_loader: when VBOOT starts in BOOTBLOCK ramstage_loader: when VBOOT starts in ROMSTAGE BUG=N/A TEST=tested on facebook fbg1701 Change-Id: Id5e8fd78458c09dd3896bfd142bd49c2c3d686df Signed-off-by: Wim Vervoorn Reviewed-on: https://review.coreboot.org/c/coreboot/+/36543 Reviewed-by: Frans Hendriks Tested-by: build bot (Jenkins) --- src/security/vboot/vboot_loader.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/security/vboot/vboot_loader.c') diff --git a/src/security/vboot/vboot_loader.c b/src/security/vboot/vboot_loader.c index 3aac48d174..2b7ba83503 100644 --- a/src/security/vboot/vboot_loader.c +++ b/src/security/vboot/vboot_loader.c @@ -35,7 +35,7 @@ _Static_assert(!CONFIG(VBOOT_RETURN_FROM_VERSTAGE) || int vboot_executed CAR_GLOBAL; -static void vboot_prepare(void) +void vboot_run_logic(void) { if (verification_should_run()) { /* Note: this path is not used for VBOOT_RETURN_FROM_VERSTAGE */ @@ -90,6 +90,5 @@ static int vboot_locate(struct cbfs_props *props) const struct cbfs_locator vboot_locator = { .name = "VBOOT", - .prepare = vboot_prepare, .locate = vboot_locate, }; -- cgit v1.2.3
