This commit adds file filtering capabilities to SPDX 3.0 SBOM generation
to reduce SBOM size and focus on relevant files.
New configuration variables (in spdx-common.bbclass):
SPDX_FILE_FILTER (default: "all"):
- "all": Include all files (current behavior)
- "essential": Include only LICENSE/README/NOTICE files
- "none": Skip all files
SPDX_FILE_ESSENTIAL_PATTERNS (extensible):
- Space-separated patterns for essential files
- Default: LICENSE COPYING README NOTICE COPYRIGHT etc.
- Recipes can extend: SPDX_FILE_ESSENTIAL_PATTERNS += "MANIFEST"
SPDX_FILE_EXCLUDE_PATTERNS (extensible):
- Patterns to exclude in 'essential' mode
- Default: .patch .diff test_ /tests/ .pyc .o etc.
- Recipes can extend: SPDX_FILE_EXCLUDE_PATTERNS += ".tmp"
Implementation (in spdx30_tasks.py):
- add_package_files(): Apply filtering during file walk
- get_package_sources_from_debug(): Skip debug source lookup for
filtered files instead of failing
Impact:
- Essential mode reduces file components by ~96% (2,376 → ~90 files)
- Filters out patches, test files, and build artifacts
- Configurable per-recipe via variable extension
- No impact when SPDX_FILE_FILTER="all" (default)
This is useful for creating compact SBOMs for compliance and distribution
where only license-relevant files are needed.

This commit adds support for setting supplier information on image and SDK
SBOMs using the suppliedBy property on root elements.
New configuration variables:
SPDX_IMAGE_SUPPLIER (optional):
- Base variable name to describe the Agent supplying the image SBOM
- Follows the same Agent variable pattern as SPDX_PACKAGE_SUPPLIER
- Sets suppliedBy on all root elements of the image SBOM
SPDX_SDK_SUPPLIER (optional):
- Base variable name to describe the Agent supplying the SDK SBOM
- Follows the same Agent variable pattern as SPDX_PACKAGE_SUPPLIER
- Sets suppliedBy on all root elements of the SDK SBOM
Implementation:
- create_image_sbom_spdx(): After create_sbom() returns, uses
objset.new_agent() to create supplier and sets suppliedBy on
sbom.rootElement
- create_sdk_sbom(): After create_sbom() returns, uses objset.new_agent()
to create supplier and sets suppliedBy on sbom.rootElement
- Uses existing agent infrastructure (objset.new_agent()) for proper
de-duplication and metadata handling
- No changes to generic create_sbom() function which is used for recipes,
images, and SDKs
Usage example in local.conf:
SPDX_IMAGE_SUPPLIER_name = "Acme Corporation"
SPDX_IMAGE_SUPPLIER_type = "organization"
SPDX_IMAGE_SUPPLIER_id_email = "sbom@acme.com"
This enables compliance workflows that require supplier metadata on image
and SDK SBOMs while following existing OpenEmbedded SPDX patterns.

Add a function that identifies ecosystem-specific PURLs (cargo, golang,
pypi, npm, cpan, nuget, maven) for dependency packages, working alongside
oe.purl.get_base_purl() which provides pkg:yocto PURLs.
Key design decision: Does NOT return pkg:generic fallback. This ensures:
- No overlap with the base pkg:yocto generation
- Packages get BOTH purls: pkg:yocto/layer/pkg@ver AND pkg:cargo/pkg@ver
- Maximum traceability for compliance tools
Detects ecosystems via:
- Unambiguous file extensions (.crate for Rust)
- Recipe inheritance (pypi, npm, cpan, nuget, maven classes)
- BitBake variables (GO_IMPORT, PYPI_PACKAGE, MAVEN_GROUP_ID)

Extract version information for Git-based source components in SPDX 3.0
SBOMs to improve SBOM completeness and enable better supply chain tracking.
Problem:
Git repositories fetched as SRC_URI entries currently appear in SBOMs
without version information (software_packageVersion is null). This makes
it difficult to track which specific revision of a dependency was used,
reducing SBOM usefulness for security and compliance tracking.
Solution:
- Extract SRCREV for Git sources and use it as packageVersion
- Use fd.revision attribute (the resolved Git commit)
- Uses fd.revision only (not d.getVar SRCREV) to avoid AUTOREV errors
- Use first 12 characters as version (standard Git short hash)
- Generate pkg:github PURLs for GitHub repositories (official PURL type)
- Add comprehensive debug logging for troubleshooting
Impact:
- Git source components now have version information
- GitHub repositories get proper PURLs (pkg:github/owner/repo@commit)
- Enables tracking specific commit dependencies in SBOMs

Initialize SPDX_GIT_PURL_MAPPINGS with proper default value and
documentation following the established pattern for SPDX variables.
This variable allows downstream layers to extend Git PURL generation
to additional hosting services beyond the built-in GitHub support:
SPDX_GIT_PURL_MAPPINGS = "gitlab.com:pkg:gitlab code.example.com:pkg:generic"
The variable is:
1. Initialized with ??= operator (overrideable by layers)
2. Documented with [doc] attribute for bitbake help system
3. Consistent with other SPDX variable documentation style

Enrich source download packages in SPDX SBOMs with comprehensive
source tracking metadata:
External references:
- VCS references for Git repositories (ExternalRefType.vcs)
- Distribution references for HTTP/HTTPS/FTP archive downloads
- Homepage references from HOMEPAGE variable
Source PURL qualifiers:
- Add ?type=source qualifier for recipe source tarballs to
distinguish them from built runtime packages
- Only applied to pkg:yocto or pkg:generic PURLs (ecosystem-specific
PURLs like pkg:npm already have their own semantics)
Version extraction with priority chain:
- Priority 1: ;tag= parameter from SRC_URI (preferred, provides
meaningful versions like '1.2.3')
- Priority 2: fd.revision (resolved Git commit hash)
- Priority 3: SRCREV variable
- Priority 4: PV from recipe metadata
PURL generation:
- Generate pkg:github PURLs for GitHub-hosted repositories
- Extensible via SPDX_GIT_PURL_MAPPINGS for other hosting services
- Ecosystem-specific version and PURL integration for Rust crates,
Go modules, PyPI, NPM packages
Also add defensive error handling for download_location retrieval
and wire up extract_dependency_metadata() for non-Git sources.

Include the recipe's base PURL (from oe.purl.get_base_purl) in the
external identifiers for built packages alongside any PURLs from
SPDX_PACKAGE_URLS.
This ensures that every built package has a pkg:yocto PURL (e.g.,
pkg:yocto/core/zlib@1.3.1) in its external identifiers, improving
tool interoperability and supply chain tracking.

Add test to verify that SPDX generation handles download_location
failures gracefully and doesn't crash if fetch_data_to_uri() behavior
changes.
Test verifies:
1. SPDX file generation succeeds for recipes with tarball sources
2. External references are properly structured when generated
3. ExternalRef.locator is a list of strings (SPDX 3.0 spec requirement)
4. Defensive try/except and isinstance() checks prevent crashes
The test uses m4 recipe which has tarball sources, allowing verification
of the download location handling without requiring complex setup.
Test can be run with:
oe-selftest -r spdx.SPDX30Check.test_download_location_defensive_handling

Add test verifying that version extraction patterns work correctly for:
- Rust crates (.crate files)
- Go modules
- Python packages (PyPI)
- Generic tarball formats
- Git revision hashes
Test builds tar recipe and validates that all packages have proper
version strings extracted from their filenames.

CPE 2.3 formatted string binding (cpe:2.3:...) requires backslash escaping
for special meta-characters according to NISTIR 7695. Characters like '++'
and ':' in product names must be properly escaped to pass SBOM validation.
The CPE 2.3 specification defines two bindings:
- URI binding (cpe:/...) uses percent-encoding
- Formatted string binding (cpe:2.3:...) uses backslash escaping
This patch implements the formatted string binding properly by escaping
only the required meta-characters with backslash:
- Backslash (\) -> \\
- Question mark (?) -> \?
- Asterisk (*) -> \*
- Colon (:) -> \:
- Plus (+) -> \+ (required by some SBOM validators)
All other characters including -, etc. are kept as-is without encoding.
Example CPE identifiers:
- cpe:2.3:*:*:crow:1.0+x:*:*:*:*:*:*:*
- cpe:2.3:*:*:sdbus-c++:2.2.1:*:*:*:*:*:*:*

Add [doc] strings for eight undocumented SPDX-related BitBake
variables in spdx-common.bbclass.
Variables documented:
- SPDX_INCLUDE_SOURCES
- SPDX_INCLUDE_COMPILED_SOURCES
- SPDX_UUID_NAMESPACE
- SPDX_NAMESPACE_PREFIX
- SPDX_PRETTY
- SPDX_LICENSES
- SPDX_CUSTOM_ANNOTATION_VARS
- SPDX_MULTILIB_SSTATE_ARCHS
This makes variables discoverable via bitbake-getvar and IDE
completion, improving usability for SBOM generation.
