2022-03-09commonlib/bsd: Remove cb_err_tJulius Werner
cb_err_t was meant to be used in place of `enum cb_err` in all situations, but the choice to use a typedef here seems to be controversial. We should not be arbitrarily using two different identifiers for the same thing across the codebase, so since there are no use cases for serializing enum cb_err at the moment (which would be the primary reason to typedef a fixed-width integer instead), remove cb_err_t again for now.

2021-03-16cbfs: Remove prog_locate() for stages and rmodulesJulius Werner
This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.

2020-12-03cbfs: Add verification for RO CBFS metadata hashJulius Werner
This patch adds the first stage of the new CONFIG_CBFS_VERIFICATION feature. It's not useful to end-users in this stage so it cannot be selected in menuconfig (and should not be used other than for development) yet. With this patch coreboot can verify the metadata hash of the RO CBFS when it starts booting, but it does not verify individual files yet. Likewise, verifying RW CBFSes with vboot is not yet supported. Verification is bootstrapped from a "metadata hash anchor" structure that is embedded in the bootblock code and marked by a unique magic number. This anchor contains both the CBFS metadata hash and a separate hash for the FMAP which is required to find the primary CBFS. Both are verified on first use in the bootblock (and halt the system on failure). The CONFIG_TOCTOU_SAFETY option is also added for illustrative purposes to show some paths that need to be different when full protection against TOCTOU (time-of-check vs. time-of-use) attacks is desired. For normal verification it is sufficient to check the FMAP and the CBFS metadata hash only once in the bootblock -- for TOCTOU verification we do the same, but we need to be extra careful that we do not re-read the FMAP or any CBFS metadata in later stages. This is mostly achieved by depending on the CBFS metadata cache and FMAP cache features, but we allow for one edge case in case the RW CBFS metadata cache overflows (which may happen during an RW update and could otherwise no longer be fixed because mcache size is defined by RO code). This code is added to demonstrate design intent but won't really matter until RW CBFS verification can be supported.

2020-11-21cbfs: Add metadata cacheJulius Werner
This patch adds a new CBFS "mcache" (metadata cache) -- a memory buffer that stores the headers of all CBFS files. Similar to the existing FMAP cache, this cache should reduce the amount of SPI accesses we need to do every boot: rather than having to re-read all CBFS headers from SPI flash every time we're looking for a file, we can just walk the same list in this in-memory copy and finally use it to directly access the flash at the right position for the file data. This patch adds the code to support the cache but doesn't enable it on any platform. The next one will turn it on by default.

2020-06-15security/vboot: Add option to run verstage before bootblockMartin Roth
For AMD's family 17h, verstage can run as a userspace app in the PSP before the X86 is released. The flags for this have been made generic to support any other future systems that might run verstage before the main processor starts. Although an attempt has been made to make things somewhat generic, since this is the first and currently only chip to support verstage before bootblock, there are a number of options which might ultimately be needed which have currently been left out for simplicity. Examples of this are: - PCI is not currently supported - this is currently just a given instead of making a separate Kconfig option for it. - The PSP uses an ARM v7 processor, so that's the only processor that is getting updated for the verstage-before-bootblock option.

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.)

2019-07-03vboot: Use CONFIG_VBOOT_MIGRATE_WORKING_DATA on all platformsJulius Werner
When we added CONFIG_VBOOT_MIGRATE_WORKING_DATA, the idea was that on some Arm platforms the original working data buffer was in SRAM, which stays accessbile for the whole runtime of the system. There is no reason to migrate it into CBMEM on those platforms because ramstage and the payload could continue to access it in SRAM. Now that we've had a couple of months of experience with this option, we found that most of our Arm platforms have some issue that requires migrating anyway, because BL31 often claims SRAM for itself and makes it inaccessible to the payload. On the remaining platforms, accessing SRAM from the payload is possible but still an issue, because libpayload doesn't have enough memory layout information to set up proper page tables for it, so we're accessing it uncached and at risk of alignment errors. Rather than having to figure out how to map the right SRAM range for every platform in the payload, let's just get rid of the option. memcpy()ing 12KB isn't worth this much hassle.
