- Replace CVE_CHECK_IGNORE with CVE_STATUS + [CVE_STATUS_REASONING] to be more flexible. CVE_STATUS should contains flag for each CVE with accepted values "Ignored" or "Not applicable". It allows to add a status for CVEs which could be fixed externally. - Optional CVE_STATUS_REASONING flag variable could contains a reason why the CVE status was used. It will be added in csv/json report like a new "reason" entry. - All listed CVEs in CVE_CHECK_IGNORE are copied to CVE_STATUS with value "Ignored" like a fallback.
Example of usage: CVE_STATUS[CVE-1234-0001] = "Not applicable" or "Ignored" CVE_STATUS[CVE-1234-0002] = "Not applicable" CVE_STATUS_REASONING[CVE-1234-0002] = "Issue only applies on windows" Signed-off-by: Andrej Valek <[email protected]> --- meta/classes/cve-check.bbclass | 30 +++++++++++++++++++++++++----- meta/lib/oe/cve_check.py | 6 ++++++ 2 files changed, 31 insertions(+), 5 deletions(-) diff --git a/meta/classes/cve-check.bbclass b/meta/classes/cve-check.bbclass index bd9e7e7445c..e081095037c 100644 --- a/meta/classes/cve-check.bbclass +++ b/meta/classes/cve-check.bbclass @@ -70,13 +70,17 @@ CVE_CHECK_COVERAGE ??= "1" # Skip CVE Check for packages (PN) CVE_CHECK_SKIP_RECIPE ?= "" -# Ingore the check for a given list of CVEs.
