Benjamin Robin (Schneider Electric) cf3b1a7e6d vex.bbclass: add a new class
The "vex" class generates the minimum information that is necessary
for VEX generation by an external CVE checking tool. It is a drop-in
replacement of "cve-check". It uses the same variables from recipes
to make the migration and backporting easier.

The goal of this class is to allow generation of the CVE list of
an image or distribution on-demand, including the latest information
from vulnerability databases. Vulnerability data changes every day,
so a status generated at build becomes out-of-date very soon.

Research done for this work shows that the current VEX formats (CSAF
and OpenVEX) do not provide enough information to generate such
rolling information. Instead, we extract the needed data from recipe
annotations (package names, CPEs, versions, CVE patches applied...)
and store for later use in the format that is an extension of the
CVE-check JSON output format.

This output can be then used (separately or with SPDX of the same
build) by an external tool to generate the vulnerability annotation
and VEX statements in standard formats.

When back-porting this feature, the do_generate_vex() had to be modified
to use the "old" get_patched_cves() API.

Poky

Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.

Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.

As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.

The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/

OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Contribution Guidelines

Please refer to our contributor guide here: https://docs.yoctoproject.org/dev/contributor-guide/ for full details on how to submit changes.

Where to Send Patches

As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:

OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):

BitBake (files in bitbake/):

Documentation (files in documentation/):

meta-yocto (files in meta-poky/, meta-yocto-bsp/):

If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
