2020-04-15Do not select USE_BLOBSNico Huber
The `USE_BLOBS` config only exists for idealistic reasons. If we would allow us to use blobs by default, we wouldn't need that option and could just always do it. It's generally debatable for the project as a whole, but not per board/subject.

It turns out the linker's error message already includes the line number of the dead_code() invocation. If we don't include the line number in the identifier for our undefined reference, we don't need individual identifiers at all and can work with a single, global declaration.

When dead_code() is used in inline functions in a header file, the generated function names (based on the line number) may collide with a dead_code() in the code file. Now that we are hit by such a case, we need a quick solution: Add a tag argument for all invocations in header files.

2020-04-01security/tpm: Fix compile-time elimination for SEPARATE_VERSTAGEJulius Werner
CB:35077 pulled TPM measurement code into the bootblock, with the catch that we'll only cache PCR extensions and not actually write them to the TPM until it gets initialized in a later stage. The goal of this was to keep the heavy TPM driver code out of the size-constrained bootblock. Unfortunately, a small mistake in the tspi_tpm_is_setup() function prevents the compiler from eliminating references to the TPM driver code in the bootblock on platforms with CONFIG_VBOOT and CONFIG_SEPARATE_VERSTAGE. In those cases vboot_logic_executed() is known at compile-time to be 0, but that still makes the final expression `return 0 || tpm_is_setup;`. We know that tpm_is_setup can never be set to 1 in the bootblock, but the compiler doesn't. This patch rewrites the logic slightly to achieve the same effect in a way that the compiler can follow (because we only really need to check tpm_is_setup in the stage that actually runs the vboot code).

2020-03-31security/vboot: Decouple measured boot from verified bootBill XIE
Currently, those who want to use measured boot implemented within vboot should enable verified boot first, along with sections such as GBB and RW slots defined with manually written fmd files, even if they do not actually want to verify anything. As discussed in CB:34977, measured boot should be decoupled from verified boot and make them two fully independent options. Crypto routines necessary for measurement could be reused, and TPM and CRTM init should be done somewhere other than vboot_logic_executed() if verified boot is not enabled. In this revision, only TCPA log is initialized during bootblock. Before TPM gets set up, digests are not measured into tpm immediately, but cached in TCPA log, and measured into determined PCRs right after TPM is up. This change allows those who do not want to use the verified boot scheme implemented by vboot as well as its requirement of a more complex partition scheme designed for chromeos to make use of the measured boot functionality implemented within vboot library to measure the boot process. TODO: Measure MRC Cache somewhere, as MRC Cache has never resided in CBFS any more, so it cannot be covered by tspi_measure_cbfs_hook().

2020-02-05security/intel/stm: Add STM supportEugene Myers
This update is a combination of all four of the patches so that the commit can be done without breaking parts of coreboot. This possible breakage is because of the cross-dependencies between the original separate patches would cause failure because of data structure changes. security/intel/stm This directory contains the functions that check and move the STM to the MSEG, create its page tables, and create the BIOS resource list. The STM page tables is a six page region located in the MSEG and are pointed to by the CR3 Offset field in the MSEG header. The initial page tables will identity map all memory between 0-4G. The STM starts in IA32e mode, which requires page tables to exist at startup. The BIOS resource list defines the resources that the SMI Handler is allowed to access. This includes the SMM memory area where the SMI handler resides and other resources such as I/O devices. The STM uses the BIOS resource list to restrict the SMI handler's accesses. The BIOS resource list is currently located in the same area as the SMI handler. This location is shown in the comment section before smm_load_module in smm_module_loader.c Note: The files within security/intel/stm come directly from their Tianocore counterparts. Unnecessary code has been removed and the remaining code has been converted to meet coreboot coding requirements.

2020-01-18cbfs: Remove locator conceptJulius Werner
When vboot was first integrated into CBFS it was still part of Google vendorcode. So to not directly tie custom vendorcode into the core CBFS library, the concept of cbfs_locator was introduced to decouple core code from an arbitrary amount of platform-specific implementations that want to decide where the CBFS can be found. Nowadays vboot is a core coreboot feature itself, and the locator concept isn't used by anything else anymore. This patch simplifies the code by removing it and just calling vboot from the CBFS library directly. That should make it easier to more closely integrate vboot into CBFS in the future.

2019-12-13security/vboot: Ensure firmware body size is respected againJulius Werner
CB:36845 simplified how coreboot finds the RW CBFS after vboot has and eliminated a layer of caching. Unfortunately, we missed the fact that the former cached value didn't exactly match the FMAP section... it was in fact truncated to the data actually used by vboot. That patch unintentionally broke this truncation which leads to performance regressions on certain CBFS accesses. This patch makes use of a new API function added to vboot (CL:1965920) which we can use to retrieve the real firmware body length as before. (Also stop making all the vb2_context pointers const. vboot generally never marks context pointers as const in its API functions, even when the function doesn't modify the context. Therefore constifying it inside coreboot just makes things weird because it prevents you from calling random API functions for no reason. If we really want const context pointers, that's a refactoring that would have to start inside vboot first.)

factory_initialize_tpm() calls secdata_xxx_create() (for both firmware and kernel space) and then immediately writes those spaces out to the TPM.

Also clean up some minor related stuff (VB2_CONTEXT_SECDATA_CHANGED notation is deprecated, and secdata space intialization should use the same write-and-readback function we use for updates).

The HWID in vboot GBB is an identifier for machine model. On Chrome OS, that should be provisioned in manufacturing process (by collecting real hardware information), and will be checked in system startup. For bring up developers, they usually prefer to generate a test-only string for HWID. However that format was not well documented and cause problems. Further more, most Chromebooks are using HWID v3+ today while the test-only HWID is usually v2. Non-Chrome OS developers may also prefer their own format. To simplify development process, the GBB_CONFIG now defaults to empty string, and will be replaced by a board-specific test-only v2 HWID automatically. Developers can still override that in mainboard Kconfig if they prefer v3 or other arbitrary format. BUG=b:140067412 TEST=Built 'kukui' successfully.

With the support of various algorithms and banks in tlcl_extend(), digest_algo parameter of tpm_extend_pcr() started defining the target PCR bank in TPM2 case. The OS expects coreboot to extend the SHA256 bank of BOOT_MODE_PCR. The value that the OS expects coreboot to extend into BOOT_MODE_PCR is the SHA1 digest of mode bits extended to the length of SHA256 digest by appending zero bytes. Thus the correct value for digest_algo passed into tpm_extend_pcr() for BOOT_MODE_PCR is TPM_ALG_SHA256. This didn't matter until adding the support for multiple digest introduced by patches like https://review.coreboot.org/c/coreboot/+/33252, as tlcl_extend always used SHA256 bank before.

CB:33252 wasn't reviewed by a TPM maintainer and breaks abstraction layers (pulling TSS-details into TSPI, completely changing interpretation of the arguments to tlcl_extend() based on TSS version). It's also not clear why it was implemented the way it was (should have been much easier and cleaner ways to achieve the same thing). Since the author is not reacting, let's revert it for now. It can be cleaned up and resubmitted later. (Not reverting the header changes since those are not objectionable, and there are later patches dependent on it.)

2019-08-06security/vboot: Add Support for Intel PTTChristian Walter
Add support for Intel PTT. For supporting Intel PTT we need to disable read and write access to the TPM NVRAM during the bootblock. TPM NVRAM will only be available once the DRAM is initialized. To circumvent this, we mock secdata if HAVE_INTEL_PTT is set. The underlying problem is, that the iTPM only supports a stripped down instruction set while the Intel ME is not fully booted up. Details can be found in Intel document number 571993 - Paragraph 2.10.

2019-07-31drivers/crb: Add CRB driver for TPM2 supportChristian Walter
Add the Command Response Buffer which is defined in the TPM 2.0 Specs. CRB can be specified with MAINBOARD_HAS_CRB_TPM, even though it is actually SoC/SB specific.

2019-07-29Revert "src/security/vboot: Add option to skip display init with vboot 2.0"Christian Walter
This reverts commit 598af2e2c2785c00eb4290cdcefe1082b2a6f858. Reason for revert: This commit breaks every board with VBOOT enabled if the platform is apollolake, broadwell, skylake, baswell, baytrails or icelake. The reason is, that the SoC selects VBOOT_MUST_REQUEST_DISPLAY by default, and this has a dependency now on VBOOT_MAY_SKIP_DISPLAY_INIT. This will only be auto-selected if it is a CHROMEOS platform.
