From ea0ff5cd4efb1d67820572fb0d7d1d8da0fc1dc1 Mon Sep 17 00:00:00 2001 From: Harald Hoyer Date: Fri, 28 Jul 2017 09:46:05 +0200 Subject: [PATCH] boot/efi: don't hard fail on error for tpm measure (#6473) Display the error for a small amount of time, but don't fail hard. In case of a faulty BIOS, a TPM error should not prevent the boot. If something cares about the PCM measurement, it will be noticed anyway later on. Especially important now, that TPM measurement is the default now on some distribution builds. https://bugzilla.redhat.com/show_bug.cgi?id=1411156 (cherry picked from commit 522aa9f5f8755d7389131da41bd60b6276917ff2) --- src/boot/efi/boot.c | 3 +-- src/boot/efi/stub.c | 3 +-- 2 files changed, 2 insertions(+), 4 deletions(-) diff --git a/src/boot/efi/boot.c b/src/boot/efi/boot.c index 1e990b3825..316e95a72b 100644 --- a/src/boot/efi/boot.c +++ b/src/boot/efi/boot.c @@ -1657,8 +1657,7 @@ static EFI_STATUS image_start(EFI_HANDLE parent_image, const Config *config, con loaded_image->LoadOptionsSize, loaded_image->LoadOptions); if (EFI_ERROR(err)) { Print(L"Unable to add image options measurement: %r", err); - uefi_call_wrapper(BS->Stall, 1, 3 * 1000 * 1000); - return err; + uefi_call_wrapper(BS->Stall, 1, 200 * 1000); } #endif } diff --git a/src/boot/efi/stub.c b/src/boot/efi/stub.c index bab5d46de9..2562228090 100644 --- a/src/boot/efi/stub.c +++ b/src/boot/efi/stub.c @@ -94,8 +94,7 @@ EFI_STATUS efi_main(EFI_HANDLE image, EFI_SYSTEM_TABLE *sys_table) { loaded_image->LoadOptionsSize, loaded_image->LoadOptions); if (EFI_ERROR(err)) { Print(L"Unable to add image options measurement: %r", err); - uefi_call_wrapper(BS->Stall, 1, 3 * 1000 * 1000); - return err; + uefi_call_wrapper(BS->Stall, 1, 200 * 1000); } #endif }
