From e40d83a4f0e871c7e91e19d0d6f77168f3cc667d Mon Sep 17 00:00:00 2001 From: Kamel Bouhara Date: Mon, 28 Jul 2025 15:30:44 +0200 Subject: [PATCH] spdx30_tasks: Add support for exporting PACKAGECONFIG to SPDX Introduce the SPDX_INCLUDE_PACKAGECONFIG variable, which when enabled causes PACKAGECONFIG features to be recorded in the SPDX document as build parameters. Each feature is recorded as a DictionaryEntry with key PACKAGECONFIG: and value enabled or disabled, depending on whether the feature is active in the current build. This makes the build-time configuration more transparent in SPDX output and improves reproducibility tracking. This makes the build-time configuration more transparent in SPDX output and improves reproducibility tracking. In particular, it allows consumers of the SBOM to identify enabled/disabled features that may affect security posture or feature set.
