Error:
.../brillo/system/bvb/refimpl/bvb_verify.c:168:27:
error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
if (!bvb_safe_add(NULL, (uint64_t) data, length)) {
^
The error means that converting a pointer to unsigned int can be
dangerous.
We converts a pointer to 64bit unsigned int which is safe (at
least till we are not going to run this code on 128bit system for
example)
We can make compiler happy by useing uintptr_t as a temp variable.
uintptr_t is guaranteed to be wide enough that converting a pointer
to uintptr_t and back again will yield the original pointer value.

This change introduces a script to verify only symbols starting with
bvb_ are used in the reference implementation. This is to catch mistakes
where the standard C library (e.g. malloc() or printf()) is used by
mistake.
TEST=Manually tested by using malloc() in bvb_verify().
BUG=None

This makes it easier to see exactly which files belong to the reference
implementation.
BUG=None
TEST=Code builds and unit tests pass.

This hides the code implementing the few RSA and SHA bits we're using
from the application, enabling us to change to another crypto
implementation in the future if we so desire.
Since we have limited control over the build system used, this is
best-effort by playing C preprocessor games. The approach used is
similar to how other C libraries do this (GLib, GTK+, D-Bus).
BUG=None
TEST=Manually tested.

This directory contains
- The specification for the Brillo Verified Boot boot image format; and
- A reference implementation (intended for use in boot loaders); and
- tooling for generating and signing boot images; and
- tooling for using dm-verity on the rootfs; and
- unit tests for the above code.
See the README file for more details.
The code in the files bvb_rsa.[ch], bvb_sha*.[ch], bvb_sysdeps*.[ch] is
based on code from the ChromiumOS vboot_reference project.
