vboot currently uses the |SHA256_CTX| name, which is claimed by OpenSSL.
To work around this, it defines OPENSSL_NO_SHA, but that can't be done
at compile time:
The OPENSSL_NO_* defines are set by OpenSSL to reflect the configuration
that it was built with so that users of OpenSSL can disable features as
needed. They can affect the contents of structures any thus the ABI of
the library.
If these defines are set outside of OpenSSL, then the library and the
code that uses it will have incompatible ABIs. At that point it's only
functioning by blind luck.
This change renames the name-collisions so that this hack isn't needed.
This is the same change as was made internally in cl/85758149.

The USB Type-C chargers released with Samus ("Pixel (2015)") have
upgradable firmware. Those firmware images are currently signed
by some custom scripts. This adds support for those images to
futility, so that those custom scripts can be replaced.
Note that due to space considerations, the usbpd firmware images
don't have room for handy things like an FMAP or headers for the
signatures. Accordingly, all the normally variable factors (image
size, signature algorithms, etc.) are hard coded and the image
itself just looks like a bunch of random numbers. Because of
this:
1. There's no way to recognize this type of file, and nothing to
display about it.
2. You have to give the "--type usbpd1" arg to the sign command.
3. I'm designating this file type "v1" because I hope that the
firmware for any future adapters will be more readily
identifiable.
BUG=chromium:231574
BRANCH=none
TEST=make runtests
This adds a new test that signs usbpd1 firmware images using
futility, and compares the result to the same files signed by the
custom scripts, ensuring that they are bitwise identical.

This moves the functions that handle BIOS file types into a
separate set of source files. BIOSes are constructed from other
components arranged in particular ways, so they shouldn't be

This declares the options for the sign and show commands in a
header file.
We want to split the code for logically separate file types into
separate source files, but we don't want to have multiple
option-parsing routines, so that we can be sure we're using the
same option names consistently (for example, --hash_alg always
takes the same args and means the same thing).

This allows the user to manually specify the type of an input

This also adds a test to ensure that futility doesn't coredump if
you give it the wrong type (although I'm sure it's not exhaustive).

Instead of calling futil_traverse() to iterate through a preset
list of functions, this establishes a separate show() and sign()
function for each type of file.
The only significant change is that walking through the FMAP areas
within BIOS images is done in BIOS-specific functions instead of
that being the "normal" case with every other type of file
skipping that traversal.
This is a refactoring only. There is no externally visible change.

We want a quick and human-friendly way to match keys with
signatures, so we decided to give each key a unique GUID and
carry that ID around when signing things.
But then we realized that we could autogenerate a unique
identifier from the .pem file itself, which is even better
because then we can match our binary keypair structs with the
openssl file used to generate them.
This change replaces the GUID id with a sha1sum calculated from
the public key's "keyb" blob.

Because all of our private key structs carry around the openssl
struct rsa_st data blobs, we can use those blobs to extract the
corresponding public key and generate a digest of it.
This lets us match our public and private keys without having to
rely on the filenames. There's no crypto verification without
actually *using* them, of course, but it's handy for quick reference.

The vb2_verify_fw command is used only in a host-side test. It
doesn't need to be built into futility. This makes it a separate
executable used just for that test.

Note that tests/vb2_firmware_tests.sh still passes, now using an

Adding functionality to allow for rebuilding of vmlinuz after it
has been processed into vblock and header stripped. Basically appends
the 16-bit header of a vmlinuz image onto the end of the vblock.
BUG=chromium:438302
BRANCH=none
TEST=Successfully ran "make runalltests".
Also, ran:
1. Repack kernel block (so that 16-bit header is included):
"vbutil_kernel --pack kern_0 ..."
2. Verify kernel: "vbutil_kernel --verify kern_0 ... ". This should
be done before booting into kernel, but not necessary for it to work.
3. Rebuild vmlinuz image:
"vbutil_kernel --get-vmlinuz kern_0 --vmlinuz-out vm.out"
4. Set up kexec with vmlinuz (this should complete with no errors):
"kexec -l vm.out (other kernel cmd line args)"
5. Boot into kernel:
"kexec -e"

This patch reinstates the external GPT support which was previously
committed and reverted. Improvements since last time include:
- Cleaned-up internal interface based on code review
- Function correctly on legacy bootloaders (e.g., depthcharge before
NAND-related patches are added)
- Better comments
- Treat new field values = 0 -> not use new feature
- Tests are added to ensure external GPT flag is passed down properly
The original commit had change-id
I5a77e417aea8ee9442d18c200d1b073aa5375ecf
Its commit message is reproduced below, and then an additional test.
----
To support an external GPT, disks have two new attributes:
- A binary flag indicating whether the GPT is in the same address
space as the payloads or a separate one.
- The number of sectors of the streaming portion of storage, as
opposed to the portion containing the GPT.
These have been added elsewhere to GptData (in cgptlib) and BlockDev
(in depthcharge). This patch adds the plumbing between those, including
in the DiskInfo interface between the firmware and vboot.
BUG=chromium:425677
BRANCH=none
TEST=Interactively wrote the GPT with cgpt and observed the following
boot with depthcharge to read the GPT from SPI and then read from
the proper locations in NAND flash.
TEST=make runalltests passes.
TEST=boots from USB with depthcharge from HEAD.

GBB header v1.2 adds a digest of the HWID string to the blob (and
maintains it when updated with the current futility/gbb_utility).
This CL causes VbSelectFirmware() to extend PCR1 with that HWID
digest (only for GBB header v1.2 and later, of course).
Tests are updated.
This also adds a "pcr" command to futility to help determine that
the change is working on the hardware (adds 4K bytes or fewer to
the size of the executable).
BUG=chromium:415714
BRANCH=ToT (and maybe others?)
TEST=make runtests, manual install on HW
To test on hardware, build and update a system with this change
(both the disk image and the RO firmware).
NOTE: The BIOS image must be built in a chroot that is using the
current version of futility. You may need to update your chroot
if your BIOS image still produces v1.1 GBB headers. Check with:
futility show <firmware_image.bin> | grep -B1 'digest:'
Boot the new system with a new test image, then follow these steps:
Read the BIOS:
# flashrom -r /tmp/bios.bin
Make sure the GBB has a valid digest for the HWID.
# futility show /tmp/bios.bin | grep -B1 'digest:'
HWID: SAMUS TEST 8028
digest: 4172d24f40bf72cc0ab8... <valid>
#
Extract only the sha1sum-sized part of the HWID digest:
# futility show /tmp/bios.bin | awk '/digest:/ {print $2}' | colrm 41
4172d24f40bf72cc0ab878b4c589b8fe9cf4405e
#
Simulate extending that value in a PCR using the futility "pcr"
command:
# futility pcr 4172d24f40bf72cc0ab878b4c589b8fe9cf4405e
PCR: 0000000000000000000000000000000000000000
+ 4172d24f40bf72cc0ab878b4c589b8fe9cf4405e
PCR: b6e5ffd2d898a7b15236ad22ca25f53ac1f40776
#
Finally, look at the value of PCR1. It should match the last line
of the futility pcr output:
# head /sys/class/misc/tpm0/device/pcrs | grep PCR-01
PCR-01: B6 E5 FF D2 D8 98 A7 B1 52 36 AD 22 CA 25 F5 3A C1 F4 07 76

This adds a field in the GBB header to store the sha256 digest of
the HWID string, and updates gbb_utility so that it stores the
digest when it modifies the HWID. Because this is a new field,
the GBB_MINOR_VER is incremented.

Now that futility is pretty much working as intended, we don't
have to be quite so picky in the way it's being invoked. Up until
now, it's only worked when invoked as "futility" or as one of the
built-in commands, such as "dump_fmap".
This change removes those restrictions. You can invoke futility
under any name you wish. If it recognizes the name as a built-in
command, great. Otherwise it will require a valid command as the
first arg, just like it always has.

In addtion to the new test included with this CL, I manually ran
lddtree --copy-to-tree=blah --generate-wrappers /usr/bin/futility
./blah/usr/bin/futility dump_fmap -h tests/futility/data/bios_peppy_mp.bin
Before this CL, the wrapper didn't work because the binary was
being invoked as futility.elf, which was rejected. After this CL,
the wrapper works fine.
