2020-10-22sec/intel/txt: Split MTRR setup ASM code into a macroAngel Pons
If necessary, SCLEAN needs to run in early romstage, where DRAM is not working yet. In fact, that the DRAM isn't working is the reason to run SCLEAN in the first place. Before running GETSEC, CAR needs to be torn down, as MTRRs have to be reprogrammed to cache the BIOS ACM. Further, running SCLEAN leaves the system in an undefined state, where the only sane thing to do is reset the platform. Thus, invoking SCLEAN requires specific assembly prologue and epilogue sections before and after MTRR setup, and neither DRAM nor CAR may be relied upon for the MTRR setup. In order to handle this without duplicating the MTRR setup code, place it in a macro on a separate file. This needs to be a macro because the call and return instructions rely on the stack being usable, and it is not the case for SCLEAN. The MTRR code clobbers many registers, but no other choice remains when the registers cannot be saved anywhere else. Tested on Asrock B85M Pro4, BIOS ACM can still be launched.

2020-10-17intel/txt: Add `txt_get_chipset_dpr` functionAngel Pons
Due to platform-specific constraints, it is not possible to enable DPR by programming the MCH's DPR register in ramstage. Instead, assume it has been programmed earlier and check that its value is valid. If it is, then simply configure DPR in TXT public base with the same parameters. Note that some bits only exist on MCH DPR, and thus need to be cleared. Implement this function on most client platforms. For Skylake and newer, place it in common System Agent code. Also implement it for Haswell, for which the rest of Intel TXT support will be added in subsequent commits. Do not error out if DPR is larger than expected. On some platforms, such as Haswell, MRC decides the size of DPR, and cannot be changed easily. Reimplementing MRC is easier than working around its limitations anyway.

2020-10-17security/intel/txt: Improve MTRR setup for GETSEC[ENTERACCS]Angel Pons
The BIOS ACM will check that enabled variable MTRRs do not cover more than the ACM's size, rounded up to 4 KiB. If that is not the case, launching the ACM will result in a lovely TXT reset. How boring. The new algorithm simply performs a reverse bit scan in a loop, and allocates one MTRR for each set bit in the rounded-up size to cache. Before allocating anything, it checks if there are enough variable MTRRs; if not, it will refuse to cache anything. This will result in another TXT reset, initiated by the processor, with error type 5: Load memory type error in Authenticated Code Execution Area. This can only happen if the ACM has specific caching requirements that the current code does not know about, or something has been compromised. Therefore, causing a TXT reset should be a reasonable enough approach. Also, disable all MTRRs before clearing the variable MTRRs and only enable them again once they have been set up with the new values. Tested on Asrock B85M Pro4 with a BIOS ACM whose size is 101504 bytes. Without this patch, launching the ACM would result in a TXT reset. This no longer happens when this patch is applied.

2020-10-17sec/intel/txt: Bail if var MTRRs cannot snugly cache the BIOS ACMAngel Pons
When caching the BIOS ACM, one must cache less than a page (4 KiB) of unused memory past the end of the BIOS ACM. Failure to do so on Haswell will result in a lovely TXT reset with Class Code 5, Major Error Code 2. The current approach uses a single variable MTRR to cache the whole BIOS ACM. Before fighting with the variable MTRRs in assembly code, ensure that enough variable MTRRs exist to cache the BIOS ACM's size. Since the code checks that the ACM base is aligned to its size, each `one` bit in the ACM size will require one variable MTRR to properly cache the ACM. One of the several BIOS ACMs for Haswell has a size of 101504 bytes. This is 0x18c80 in hexadecimal, and 0001 1000 1100 1000 0000 in binary. After aligning up the BIOS ACM size to a page boundary, the resulting size is 0x19000 in hexadecimal, and 0001 1001 0000 0000 0000 in binary. To successfully invoke said ACM, its base must be a multiple of 0x20000 and three variable MTRRs must be used to cache the ACM. The MTRR ranges must be contiguous and cover 0x10000, 0x8000, 0x1000 bytes, in order. The assembly code is updated in a follow-up, and relies on these checks.

2020-08-07security/intel/txt: Fix variable MTRR handlingAngel Pons
The MSR macros were treated as memory addresses and the loops had off-by-one errors. This resulted in a CPU exception before GETSEC, and another exception after GETSEC (once the first exception was fixed). Tested on Asrock B85M Pro4, ACM complains about the missing TPM and resets the platform. When the `getsec` instruction is commented-out, the board is able to boot normally, without any exceptions nor corruption.

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.

2020-05-08security: tcg-2.0: Ignore data payload for errors, fix Cr50 boot modeJulius Werner
This patch improves the response buffer handling for TPM 2.0. Previously we would allow any command to return no payload, but if there was a payload we would always try to unmarshal it according to the normal success response. This was sort of relying on the fact that the TPM usually returns no additional data after the header for error responses, but in practice that is not always true. It also means that commands without a response payload accidentally work by default even though we did not explicitly add unmarshallig support for them, which seems undesirable. Adding explicit unmarshalling support for TPM2_SelfTest which was only supported through this loophole before. This patch changes the behavior to always accept any amount of payload data for error responses but not unmarshal any of it. None of our use cases actually care about payload data for errors, so it seems safer to not even try to interpret it. For success responses, on the other hand, we always require support for the command to be explicitly added. This fixes a problem with the Cr50 GET_BOOT_MODE command where an error response would only return the subcommand code but no data after that. Also add support for a second, slightly different NO_SUCH_COMMAND error code that was added in Cr50 recently.

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.

2020-04-17ec_sync: Run EFS2 in romstagednojiri
EFS2 allows EC RO to enable PD for special cases. When doing so, it sets NO_BOOT flag to avoid booting the OS. AP needs to get NO_BOOT flag from Cr50 and enforce that. This patch makes verstage get a boot mode and a mirrored hash stored in kernel secdata from Cr50. This patch also makes romstage write an expected EC hash (a.k.a.

2020-04-01security/tpm: Fix compile-time elimination for SEPARATE_VERSTAGEJulius Werner
CB:35077 pulled TPM measurement code into the bootblock, with the catch that we'll only cache PCR extensions and not actually write them to the TPM until it gets initialized in a later stage. The goal of this was to keep the heavy TPM driver code out of the size-constrained bootblock. Unfortunately, a small mistake in the tspi_tpm_is_setup() function prevents the compiler from eliminating references to the TPM driver code in the bootblock on platforms with CONFIG_VBOOT and CONFIG_SEPARATE_VERSTAGE. In those cases vboot_logic_executed() is known at compile-time to be 0, but that still makes the final expression `return 0 || tpm_is_setup;`. We know that tpm_is_setup can never be set to 1 in the bootblock, but the compiler doesn't. This patch rewrites the logic slightly to achieve the same effect in a way that the compiler can follow (because we only really need to check tpm_is_setup in the stage that actually runs the vboot code).

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().
