While the obvious choice when it comes to hardware root of trust is +Intel Bootguard for IA platforms, the mechanism that extends the chain +of trust from hardware to bootloader, to payload/OS loader and eventually to the +OS is currently not implemented in Coreboot mainly due to licensing constraints. +This document describes the mechanism implemented in Coreboot using Google VBOOT +libraries version 2.1 that makes use of Intel BootGuard technology as Root of +Trust and extends the chain of trust to Coreboot which in turn extends it to the +payload. Note: UEFI payload will use secure boot mechanism to verify and launch +OS but that is beyond the scope of this document and will not be covered here. +More details about VBOOT support in Coreboot are available at +https://www.coreboot.org/git-docs/Intel/vboot.html. + + +## Intel BootGuard Technology + +Intel BootGuard is a platform boot integrity +protection technology. It allows initial stage of bootloader to be verified (and +measured in TPM) by a piece of firmware (ACM) which itself is verified by Intel +CPU microcode. A high level summary of the steps required to enable Intel +BootGuard are: 1. Use Intel FSP-T with Coreboot bootloader. It contains the +logic of correctly handling BtGuard enabled state. 2. Integrate ACM +(Authenticated Code module) binary in bootloader image. 3. Generate BtGuard Key +Manifest(BtG KM) and BtGuard Boot PolicyManifest(BtG BPM) and embed them in +bootloader image. a. BtG KM contains the hash of the key used for signing BtG +BPM. BtG KM is signed by the key whose hash is embedded in field-programmable +fuses. b. BtG BPM contains the hash of initial stage of boot loader. It also +stores other policies related to Intel TXT, BtG DMA protection etc. 4. Add +entries for CPU microcode patch, ACM, BtG KM and BtG BPM in FIT table. 5. +Update BootGuard related field-programmable fuses on the test platform. + + +## VBOOT in Coreboot + +The current implementation of VBOOT tool support and logic +in Coreboot is at version 2.0. The architecture, design and usage of this +feature has been described here, +https://www.coreboot.org/git-docs/Intel/vboot.html. + +### VBOOT 2.0 in Coreboot (Currently available) + +As described in the location mentioned above, the VBOOT 2.0 verified boot logic +flow works as follows. Upon boot, verstage attempts to verify the read-write +section A. It gets the public root key from GBB area and verifies the VBLOCK +area in read-write section A. If the verification is successful, then verstage +instructs Coreboot to boot rest of the firmware in read-write section A +(romstage, postcar, ramstage and payload). If the verification fails, then, +VBOOT falls back on read-only area to boot. +The flow chart below shows this flow: + +**VBOOT 2.0 Verification Flow in Coreboot** +![VBOOT_20_Flow_in_Coreboot][VBOOT_Flow_20] + +[VBOOT_Flow_20]: vboot_flow_20.png + +While this design implements verified boot to a certain extent, it does not take +into account a few use-cases and concerns some Intel customers run into. A +couple of them are as listed below, +- Some hardware designs cannot support ‘read-only’ flash region as Root of Trust + and therefore prefer Intel BootGuard technology as RoT for verified boot +mechanism. +- In some use-cases, some of the firmware components may come from different + media, for instance, customer could boot payload from USB thumb drive instead +of SPI flash. In that case, the entire read-write section will not have all the +firmware components. There needs to be a mechanism to verify payload along with +other components. +- In exisiting implementation, all the firmware components in the boot chain are + verified in verstage. This may result in a TOCTOU attack where right after the +verification phase, some firmware stages/components (such as payload, FSP, etc.) +can be swapped with malware. To extend the vboot security model, the mechanism +described below is proposed where the root of trust Bootguard begins by +verifying the IBB and the chain of trust is extended only to the next +stage/component at every verification pass. For instance, once Bootguard +verifies IBB which contains verstage, romstage and postcar), postcar then uses +the VBOOT mechanism to verify ramstage. Once ramstage is loaded into DRAM, +ramstage in turn will verify FSP and payload. + +### Proposed Changes using VBOOT2.1 Libraries + +The proposed changes are described as follows. Upon power on of the device, +Intel Bootguard attempts to verify IBB. IBB in this case, replaces the read-only +portion of the flash map and contains bootblock, verstage, romstage and postcar +stage. If the verification is successful, Intel Bootguard launches IBB and the +system boots until postcar stage. In postcar stage, GBB is extracted and GBB +verified the VBLOCK. Once VBLOCK is verified, postcar stage extracts the +ramstage hash from VBLOCK and verifies the ramstage after it has been loaded +into DRAM. This is done to ensure maximum security. Once ramstage is verified, +ramstage is launched. At this point, ramstage extracts the hash of FSPS, DSDT +ACPI table and payload in that order, and verifies and launches them +sequentially. At any point, if the verification fails, the system boot will +halt. + +**Stage/Blob Verification using VBOOT2.1 Library** +![VBOOT_Stage_Blob_Verification][VBOOT_Flow_21] + +[VBOOT_Flow_21]: vboot_flow_21.png + +### Flash Partition and Code Flow in Coreboot + +**Flash Partition for Verification using VBOOT 2.1 Library** +![VBOOT_Verification_2_1_Flash][Flash_Partition] + +[Flash_Partition]: flash_partition.png + +**Verification Logic using VBOOT 2.1 Library** +![VBOOT_Verification_2_1_Logic][vboot_21_logic] + +[vboot_21_logic]: vboot_21_logic.png + -- To view, visit https://review.coreboot.org/c/coreboot/+/32159 To unsubscribe, or for help writing mail filters, visit https://review.coreboot.org/settings Gerrit-Project: coreboot Gerrit-Branch: master Gerrit-Change-Id: I1eb174bb4f4d84eb8f6befdce18421b6b85ccc02 Gerrit-Change-Number: 32159 Gerrit-PatchSet: 1 Gerrit-Owner: Amol N Sukerkar <amol.n.sukerkar(a)intel.com> Gerrit-MessageType: newchange

Change in ...coreboot[master]: util/amdfwtool: Add multilevel PSP directory table

( https://review.coreboot.org/c/coreboot/+/33398 Change subject: util/amdfwtool: Add multilevel PSP directory table ...................................................................... util/amdfwtool: Add multilevel PSP directory table Add the ability to generate two PSP directory table levels. The PSP is capable of supporting two levels, with the primary intended to remain pristine for the life of the system, and the second updatable. In the event the second becomes corrupted, the primary is still sufficient to allow a recovery of the other. This patch modifies no directory table structures currently in use. The soc or southbridge must pass an argument to force building the secondary table.

AtomBIOS ROMs are required to enable the integrated and discrete VGA adapters, however to add the discrete GPU support you will also need to apply these patches: https://review.coreboot.org/c/coreboot/+/33874 - CB:33874 = CB:31448 + CB:31450 G505S dGPU support: scripts for applying the unofficial (not-merged-yet) patches Save to ./coreboot/ then run ./extract_atombios_roms.sh and ./check... . Could analyze these ROMs with AtomDis - https://cgit.freedesktop.org/~mhopf/AtomDis/ Three ROMs are suitable for Lenovo G505S with A10-5750M APU installed, and two as a bonus: for ASUS AM1I-A with Athlon-5370 APU (iGPU HD-8400 / R3-Series) and for ASUS A88XM-E with A10-6700 APU installed (iGPU HD-8670D).

Hello Iru Cai, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/34357 to review the following change. Change subject: autoport: search for the HDA device on PCH ...................................................................... autoport: search for the HDA device on PCH Haswell has its Mini-HD device and is at card0, so we need to search for the PCH HD Audio device instead of using card0.

Change in coreboot[master]: util/kconfig: Uprev to Linux 5.3's kconfig

TODO: - more commits that bring back our modifications, both directly in the code and as a diff in a patches/ subdirectory.
