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/arch/x86/postcar_loader.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'src/arch/x86') diff --git a/src/arch/x86/postcar_loader.c b/src/arch/x86/postcar_loader.c index 0a5d50cc1a..868b770c18 100644 --- a/src/arch/x86/postcar_loader.c +++ b/src/arch/x86/postcar_loader.c @@ -23,6 +23,7 @@ #include #include #include +#include static inline void stack_push(struct postcar_frame *pcf, uint32_t val) { @@ -171,6 +172,8 @@ static void load_postcar_cbfs(struct prog *prog, struct postcar_frame *pcf) .prog = prog, }; + vboot_run_logic(); + if (prog_locate(prog)) die_with_post_code(POST_INVALID_ROM, "Failed to locate after CAR program.\n"); -- cgit v1.2.3
