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.

2020-03-31security/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().

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. 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).
