Some additional checks related to secure version of the application in
anti-rollback case have been added to avoid any attempts to boot lower
security version but valid application (e.g., passive partition image).
- Read secure_version under sha256 protection
- First check has been added in the bootloader to ensure correct secure
version after application verification and loading stage. This check
happens before setting up the flash cache mapping and handling over
the final control to application. This check ensures that application
was not swapped (e.g., to lower security version but valid image) just
before the load stage in bootloader.
- Second check has been added in the application startup code to ensure
that currently booting app has higher security version than the one
programmed in the eFuse for anti-rollback scenario. This will ensure
that only the legit application boots-up on the device for
anti-rollback case.
Currently sbom manifest is checked only in .gitmodules and
this check is done in pre-commit and also in CI. Meaning it's running
three times(pre-commit before push if user has it enabled, in CI
as there is the pre-commit run again and again with test in CI). Since
esp-idf-sbom contains a full manifest validation support and pre-commit
plugin for it, let's use it. This removes all the current sbom testing
and replaces it with a signle pre-commit plugin which validates all
manifests files(sbom.yml, idf_component.yml, .gitmodules and also
referenced manifests) in repository. Note that this checks all
manifests, not only ones which were modified. The check is reasonably
fast though, so it should not cause any problem. The reason for
validating all manifest files is that we want to make sure that the sbom
information in .gitmodules is updated too and that the hash
recorded in .gitmodules is up-to-date. Meaning submodule update
would not trigger this plugin, because no manifest was changed.

Current version of the test is using "git-submodule foreach", which
requires submodules to be initialized. Non-initialized submodules are
ignored. Our CI is not performing submodule initialization, but instead
it only downloads the submodule content in tools/ci/ci_fetch_submodule.py
from cache and copies it into the submodule path.
Since we already know the submodule path from .gitconfig, we can use it
as argument to git-ls-tree and avoid calling git-submodule at all. This
allows to perform the test even if the submodules are not initialization
and also it makes the code simpler.

Conflicts:
- protobuf-c submodule version and hash changed to v1.4.0
- removed pytest dependency
This adds SBOM information for submodules, which are not managed
by Espressif. Meaning there is no fork for them in the espressif
namespace. Other submodules should add sbom.yml manifest file to
the root of their git repository.
The SBOM information for submodules is stored in the .gitmodules file.
Each SBOM related variable has the "sbom-" prefix and the following
variables may be used:
sbom-version:
submodule version
sbom-cpe:
CPE record if available in NVD. This will be used by the SBOM
tool to check for possible submodule vulnerabilities. The
version in the CPE can be replaced with the "{}" placeholder,
which will be replaced by the "sbom-version" value from above.
sbom-supplier:
Person or organization who is providing the submodule.
It has to start with "Person:" or "Organization:" prefix
as required by the SPDX-2.2 standard.
sbom-url:
URL to the project if exists, e.g. github.
sbom-description:
Project description.
sbom-hash:
Submodule SHA as recorded in the git-tree. This field is used by
CI to check that the submodule checkout hash and info in .gitmodules
are in sync. IOW if submodule is updated and it has SBOM info in
.gitmodules, the .gitmodules has to be updated too. The test is
part of this commit. The checkout has of the submodule can be found
by using "git submodule status".

This extends information provided in the project_description.json file.
Newly added information can be used in the SBOM generating tool and
also to improve hints regarding the the component dependency issues.
Added fields
version:
This adds versioning to the project_description.json file,
so it's easy to identify if it contains the required information.
project_version:
Can be used as a version for the resulting binary e.g. `hello_world.bin`.
idf_path:
This one is probably not necessary, but it allows tools to run even without
esp-idf environment exported(e.g. export.sh).
c_compiler:
The `CMAKE_C_COMPILER` value with full path to the compiler binary. This can
be used to get information about toolchain, which was used to build the project.
common_component_reqs:
List of common components as presented in cmake's __COMPONENT_REQUIRES_COMMON
and set in tools/cmake/build.cmake:__build_init().
build_component_info:
Detailed information about components used during build. It's a
dictionary with the component name as a key and each component has
a dictionary with detailed information. Following is an example for
the efuse component.
"efuse": {
"alias": "idf::efuse",

Currently make_json_list() returns '[ "" ]' for empty cmake list. Fix this
so empty json list is returned instead.
