[PATCH v5 0/4] generate-cve-exclusions: Add a .bbclass

[ValentinBoudevin <valentin.boudevin@gmail.com>]

Changes since v4:
- Patch 2/4:
  * Renamed the bbclass to kernel-generate-cve-exclusions.bbclass to better reflect its purpose.
  * Add new variable ENABLE_KERNEL_CVE_EXCLUSIONS to enable/disable the
  feature.
  By default, the feature is disabled to avoid unexpected behavior on
  existing builds with linux-yocto.
  * Add new "__anonymous" python function to setup the variables SRC_URI and SRCREV only if
  this feature is enabled with ENABLE_KERNEL_CVE_EXCLUSIONS.
  Also prevent from modifying SRC_URI and SRCREV variables in the default linux-yocto usecase.
  Now, the recipe does not have any impact on the basic "linux-yocto" recipe if the feature is disabled.
  * Add new variables GENERATE_CVE_EXCLUSIONS_DESTSUFFIX and
  GENERATE_CVE_EXCLUSIONS_UNPACK_DIR to customize the working directory path of the
  class.
- Patch 4/4:
  * Update the inherit statement in linux-yocto.inc to reflect the new name of the bbclass with
  "kernel-generate-cve-exclusions".

Changes since v3:
- Patch 2/4:
  * Add variables to control offline mode, source URI and
  SRCREV for deterministic testing (GENERATE_CVE_EXCLUSIONS_SRC_URI,
  GENERATE_CVE_EXCLUSIONS_SRCREV, GENERATE_CVE_EXCLUSIONS_NETWORK).
  * Updated generate_cve_exclusions task scheduling to be executed before
  do_cve_check.

Changes since v2:
- Patch 4/4: Inherit the new bbclass in linux-yocto.inc instead of
  individual recipes.

Changes since v1:
- Patch 2/4: Removed the mandatory execution of the
  generate-cve-exclusions class on every build. It now needs to be
  manually run using:
    bitbake -c generate-cve-exclusions <kernel-recipe>

ValentinBoudevin (4):
  generate-cve-exclusions: Add --output-json option
  generate-cve-exclusions: Add a .bbclass
  generate-cve-exclusions: Move python script
  linux: Add inherit on generate-cve-exclusions
