This reverts commit 87663c3bef0f6b198945cf3eb83632f461a5d6f8.
The parent CL to this commit should be sufficient to resolve the
failure that prevented "crossystem board_id" on ARM from working.
Original change's description:
> crossystem: Add board_id property
>
> futility is one of a few places in ChromeOS that uses "mosys platform
> version". The goal is to remove this command from mosys.
>
> This commit adds a new property to crossystem, "board_id", which
> reads the board revision from SMBIOS/FDT, and replaces the call in
> futility with the appropriate VbGetSystemPropertyInt.

It is still being debated who is supposed to make sure that the GBB
flags are set to zero before the root of trust validation is granted
to the AP firmware image, but as of today the approach is that the GBB
flags must be zero at AP RO validation time.
The problem is that when AP RO space signature is created GBB flags
can be set to a non-zero value.
With this patch when AP RO areas contents is hashed, in case GBB flags
are included in one of the ranges, the flags are not read from the
flash, and substituted with zero.
During validation the real flags value is used. A unit test is added
to verify various futility gscvd GBB related situations, the blobs for
the unit test were extracted from a Nivviks firmware image.

It turns out that if two processes try to read the same GPIO at the
same time that one of them will fail because the GPIO is
"busy".
This is really by design of the kernel's GPIO API. In order to read a
value, each userspace process "requests" control of the GPIO and then
queries it. There doesn't appear to be any way to "wait" for a GPIO
that's been requested by someone else--we just need to wait a bit and
try again later. ...so that's what we'll do.
Without this patch, if you run the following script on a
write-protected sc7180-trogdor class device in two shells at the same
time:
old_val=""
while true; do
val=$(crossystem wpsw_cur)
if [[ "${val}" != "${old_val}" ]]; then
echo "$(date): ${old_val} => ${val}"
old_val="${val}"
fi
done
Then you'll see stuff like this:
GPIO_GET_LINEHANDLE_IOCTL: Device or resource busy
Tue Oct 18 11:34:01 PDT 2022: 1 => 0
Tue Oct 18 11:34:01 PDT 2022: 0 => 1
GPIO_GET_LINEHANDLE_IOCTL: Device or resource busy
Tue Oct 18 11:34:01 PDT 2022: 1 => 0
Tue Oct 18 11:34:01 PDT 2022: 0 => 1
The 0 actually comes from the fact that crossystem falls back to
`GetVdatInt(VDAT_INT_HW_WPSW_BOOT)` if it fails to read the GPIO and
that value isn't initted to anything on trogdor (VDAT_INT_HW_WPSW_BOOT
is deprecated and not populated on trogdor).
It is postulated that the above problem is causing some parts of the
system to get confused about the write protect state of devices.

This patch adds support for signing and verification of coreboot images
supporting VBOOT_CBFS_INTEGRATION. Images with config option
CONFIG_VBOOT_CBFS_INTEGRATION=y will be signed with CBFS metadata hash
in signature. vb2api_get_metadata_hash() should be used to extract hash
value from VBLOCK and then should be used to verify CBFS metadata.
To support full verification, CBFS file data verification should also be
enabled and correctly handled.

The --allow-multiple-definition linker option was added in CL:6770 to
allow mocking functions. Now that we're exclusively using the weak
attribute (or equivalently test_mockable in vboot_reference) in other
firmware repositories (coreboot, depthcharge) for unit testing, the
--allow-multiple-definition option should no longer be needed.
In addition, one problem with --allow-multiple-definition is that, when
a function being mocked is automatically inlined by compiler
optimization, the mock function may not be called at all, leading to
unexpected behavior. Marking that function as test_mockable can prevent
this situation.
Therefore, add test_mockable to all the functions being mocked, and
remove the linker option from Makefile.

Crdyboot uses the kernel's own EFI boot stub to actually launch the
kernel, so the "pick apart" operations done by futility on x86 kernels
aren't desired. Skip those operations if the kernel contains the builtin
EFI stub. This will only affect the reven board, as only the reven
kernel config has CONFIG_EFI_STUB enabled.
To detect whether the kernel was built with the EFI stub, check the
first two bytes of kernel data for the COFF header magic bytes "MZ".
Tested by running `vbutil_kernel --pack` on two amd64 kernels, one with
CONFIG_EFI_STUB enabled and one with it disabled. Full command:
futility --debug vbutil_kernel
--pack out.img
--keyblock /usr/share/vboot/devkeys/recovery_kernel.keyblock
--signprivate /usr/share/vboot/devkeys/recovery_kernel_data_key.vbprivk
--version 1
--config config.txt
--bootloader /lib64/bootstub/bootstub.efi
--vmlinuz vmlinuz.bin
--arch amd64
In the kernel with the EFI stub the debug output includes "EFI boot stub
detected", the other one does not.

Utility programs in vboot sometimes use subprocess_run to execute
another program like flashrom or cbfstool. This change makes it easier
to debug these utilities by logging executed subprocess and its
arguments.
This change also fixes futility vb2ex_printf() implementation.
Previously use of VB2_DEBUG_RAW() calling vb2ex_printf(NULL, ...) was
unnecessarily trying to print NULL as function name, which was not
intended behavior.

This patch moves the connection to the vb2ex_hwcrypto API further down
the stack, into the low-level vb2_digest and vb2_hash APIs. These
functions will now take an extra allow_hwcrypto argument that the caller
can use to deny or allow hwcrypto by policy. If allowed, the function
will try HW crypto first and fall back to the software implementation if
the selected algorithm is not supported. vb2_hwcrypto_allowed() is made
available to external callers as a vb2api function to make that decision
in most cases (for others, like userspace tools and testing, HW crypto
is generally not used anyway and they can just pass `false`).
Since vb2ex_hwcrypto_digest_init() takes a data_size argument for the
total amount of bytes expected, vb2_digest_init() will now also need to
take this extra argument. But since the total data size cannot always be
known in advance, callers are allowed to pass 0 to indicate that the
size is unknown. The software implementations work either way, and HW
crypto implementations will now need to check if data_size is 0 and
return HWCRYPTO_UNSUPPORTED if they cannot handle this case.
While we're touching everything anyway, let's take this opportunity to
retire the vb2_digest_buffer() API in favor of the newer and usually
more convenient vb2_hash_calculate(), so we can limit the amount of
separate APIs we have to support going forward.

In vb2_get_gbb, abort if gbb_offset is zero. This ensures that functions
like vb2api_gbb_get_flags won't try to read garbage GBB data if the
context hasn't been properly initialized.
Some additional changes made to fix tests:
1. In vb2_set_boot_mode, don't access GBB unless needed.
2. In vb2api_get_dev_default_boot_target, use vb2api_gbb_get_flags
instead of vb2_get_gbb to make it easier to mock. This is needed for
depthcharge tests.
3. Make vb2api_get_debug_info tolerant of GBB not being set. This is
needed for depthcharge tests.

Recent discussions have brought us to the conclusion that we probably
want to include the SI_DESC section on Intel mainboards in the GSCVD
verified areas, since it contains soft straps that may affect
pre-coreboot behavior. The problem is that while this section itself
generally doesn't change, it is part of the larger Intel-specific SI_ALL
section that also contains the ME code and data -- which _can_ be
overwritten, so we usually place it in the RW part of the flash. The
section is instead protected from unauthorized software access by
platform-specific mechanisms.
This patch modifies `futility gscvd` so that it will also accept
verification ranges in an SI_ALL region (if it exists), not just in
WP_RO.

crrev.com/c/3665477 started using `--unpack` rather than
`--sb_extract` for self-extracting firmware update bundles.
Unfortunately, existing prebuilt artifacts used by signer tests are
old and only support `--sb_extract`, and hence fail with recent
vboot_reference that includes this change.
This change simply reverts the option back to `--sb_extract` for
unpacking self-extracting bundles.

This patch adds --keyset option for sign command for BIOS_IMAGE,
RAW_FIRMWARE, RAW_KERNEL and KERN_PREAMBLE file types. The default value
of this option is '/usr/share/vboot/devkeys'. It allows futility to load
public and private keys, and keyblocks from under this path, when they
were not provided manually using their respective options.
Files loaded by default for BIOS_IMAGE and RAW_FIRMWARE:
- ${keysetdir}/firmware_data_key.vbprivk
- ${keysetdir}/firmware.keyblock
- ${keysetdir}/kernel_subkey.vbpubk
Files loaded by default for RAW_KERNEL:
- ${keysetdir}/kernel_data_key.vbprivk
- ${keysetdir}/kernel.keyblock
File loaded by default for KERN_PREAMBLE:
- ${keysetdir}/kernel_data_key.vbprivk

The `--manifest` (do_manifest) command needs to scan most firmware
images in the archive to build up the right information. That can be ~2s
for a 200MB archive even though we just need the version string. 2s is
usually fast enough for developers when they want to check the archive
contents, but that is too slow if the boot time scripts (for example,
CSME updater) need to collect the information.
As a result, we want to allow overriding how the updater gets the
manifest. For most systems that the firmware archive is created by the
buildbot or the signerbot, the scripts can use "--manifest --fast" to
retrieve the cached JSON manifest file.

Currently, make coverage is broken due to two issues:
1. The optimization option -O0 ignores the inline specifier in
firmware/2lib/2sha256_x86.c:46 and 52. This will violate the
compile-time constraint "i" and cause a build failure.
Fix this issue by using -Og instead of -O0.
2. The coverage_html requires ${COV_INFO}.* files which are generated in
coverage_init and runtests. We need to add prerequisites to prevent
potential errors while running with "-j".

When the hash file of auxfw is not found in the CBFS, VB2_ERROR_UNKNOWN
will be returned from vb2ex_auxfw_check(), causing the device to enter
reboot loop. Similar to how we handle missing ecrw.hash, vb2api_fail()
should be called, so that the device will try to boot from the other
slot, and if the hash is still missing, recovery will be triggered.
Call vb2api_fail() from vb2api_auxfw_sync() using the 3-argument form of
VB2_TRY(). Add a unit test to prevent regression.
