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.

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

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.

2020-10-26vboot: Disable vboot functions in SMMJulius Werner
SMM does not have access to CBMEM and therefore cannot access any persistent state like the vboot context. This makes it impossible to query vboot state like the developer mode switch or the currently active RW CBFS. However some code (namely the PC80 option table) does CBFS accesses in SMM. This is currently worked around by directly using cbfs_locate_file_in_region() with the COREBOOT region. By disabling vboot functions explicitly in SMM, we can get rid of that and use normal CBFS APIs in this code.

2020-06-19Kconfig: Escape variable to accommodate new Kconfig versionsPatrick Georgi
Kconfig 4.17 started using the $(..) syntax for environment variable expansion while we want to keep expansion to the build system. Older Kconfig versions (like ours) simply drop the escapes, not changing the behavior. While we could let Kconfig expand some of the variables, that only splits the handling in two places, making debugging harder and potentially messing with reproducible builds (e.g. when paths end up in configs), so escape them all.

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.

2020-04-28security/lockdown: Write-protect WP_ROPatrick Rudolph
Allow to write protect only the WP_RO region in case of enabled VBOOT. One can either lock the boot device in VERSTAGE early if VBOOT is enabled, or late in RAMSTAGE. Both options have their downsides as explained below. Lock early if you don't trust the code that's stored in the writeable flash partition. This prevents write-protecting the MRC cache, which is written in ramstage. In case the contents of the MRC cache are corrupted this can lead to system instability or trigger unwanted code flows inside the firmware. Lock late if you trust the code that's stored in the writeable flash partition. This allows write-protecting the MRC cache, but if a vulnerability is found in the code of the writeable partition an attacker might be able to overwrite the whole flash as it hasn't been locked yet.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.

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().

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.)

2019-12-09EC sync: Properly handle VBERROR return codes from vb2api_ec_syncTim Wawrzynczak
Some return codes were missed when implementing this initially; the vboot logic can require the system to command the EC to reboot to its RO, switch RW slots or it can require a poweroff of the SoC. This patch appropriately handles these return codes. BUG=b:145768046 BRANCH=firmware-hatch-12672.B TEST=ODM verified this patch fixes the issues seen.

2019-12-06vboot: Clear secdata change flags after factory initJulius Werner
factory_initialize_tpm() calls secdata_xxx_create() (for both firmware and kernel space) and then immediately writes those spaces out to the TPM. The create() functions make vboot think it just changed the secdata (because it reinitialized the byte arrays in the context), so we also need to clear the VB2_CONTEXT_SECDATA_xxx_CHANGED flags again, otherwise vboot thinks it still needs to flush the spaces out to the TPM even though we already did that. 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).

Going forwards, vb2ex_commit_data will be used to flush both nvdata and secdata. The patch that is circularly dependent on this lies between a patch that makes vboot no longer build and the patch that fixes that, so we have to pull the whole thing in at once to sort out the mess.
