2020-07-15security/vboot: ensure that NVMEM is saved on every kernel space writeJett Rink
If the AP actually needs to write to the TPM, then it is important and the TPM should commit those changes to NVMEM immediately in case there is an unexpected power loss (e.g. from a USB-C port partner reset upon cold reboot request).

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.

There have been two cases of incompatibilities between overlapping changes, and they need to be resolved in a single commit to unbreak the tree: 1. CB:40389 introduced a new use of write_secdata while CB:40359 removed that function in favor of safe_write. Follow the refactor of the latter in the code introduced by the former. 2. CB:39849 changed google_chromeec_get_usb_pd_power_info()'s interface and adapted all its users.

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().

2020-01-18cbfs: 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.
