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.

Having file "classes" like this seems unnecessary, and it also seems
unlikely that anyone will agree what goes in each class. A variable
with a list of regexes that is used to filter the files is fine, but
leave it up the end users to decide what should be included/excluded.
IOW, drop all these variables and just have
SPDX_FILE_PATTERNS/SPDX_FILE_EXCLUDE_PATTERNS variable(s), which
default to empty and do nothing if so.

I'm not sure why this change is in this patch? Same for the other
following variables.

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)
- Fallback to SRCREV variable if fd.revision not available
- 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

I'm fine with using fd.revision if it's correct.... but is this a bug
in devtool and recipetool?

Minor: A set would be more efficient:
srcrev not in {"${AUTOREV}", "AUTOINC", "INVALID}:

Is it always 12, or is it "12 or however many are required to be
disambiguous" (which would require asking git)? I'd prefer to use the
full SHA-1 to prevent that.

You lambda is always the same for all of the entries in this hash
table; given that I don't see why we need it in the table.

This would fail with your example of "gitlab.com:pkg:gitlab" because
it would split into 3 parts and you are only capturing 2. You probably
want `mappings.split(":", 1), and some tests

I think using urllib can simplify this code.

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.

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.

Hi Stefano,
Thanks for the new version. We still have two selftest failures:

Can you have a look at these errors?
I also note this test failure, specifically on Fedora:

I seems a bit unrelated, so maybe just an intermittent error.

This v7 fixes two SPDX selftest failures reported by Mathieu Dubois-Briand
on the ARM autobuilder (oe-selftest-armhost builder 23/3458):
- test_download_location_defensive_handling: recipe-m4.spdx.json does not exist
- test_version_extraction_patterns: recipe-tar.spdx.json does not exist
Root cause: On the autobuilder, oe-selftest runs with parallel workers (-j 15).
All SPDX30Check tests land on the same worker but share sstate with prior tests
that use different configurations. Tests without unique extraconf may find
do_create_spdx satisfied by stale sstate stamps from earlier tests with
different SPDX configuration, causing the task to be skipped without deploying
the SPDX file to DEPLOY_DIR_SPDX.
The fix adds a unique SPDX_NAMESPACE_PREFIX to both tests, following the
established pattern from test_extra_opts which documents: "Many SPDX variables
do not trigger a rebuild... change the namespace prefix to include the hash
of the extra configuration." This ensures do_create_spdx always runs fresh
and deploys the expected recipe SPDX file.
Changes since v6:
- 07/10: Added SPDX_NAMESPACE_PREFIX extraconf to
test_download_location_defensive_handling to ensure do_create_spdx
runs fresh on autobuilder workers with shared sstate.
- 08/10: Added SPDX_NAMESPACE_PREFIX extraconf to
test_version_extraction_patterns (same fix).
Changes since v5:
- 04/10: Removed reintroduced d.getVar('SRCREV') fallback that caused
25+ devtool/recipetool selftest failures on autobuilder. Added safety
comment explaining the BBIMPORTS/AUTOREV constraint.
Changes since v4 (carried forward):
- Dropped v4 07/11: "spdx30: Include recipe base PURL in package external
identifiers" -- superseded by 874b2d301d (spdx: Add yocto PURLs,
Joshua Watt, merged to master Jan 8 2026)
Stefano Tondo (10):
spdx30: Add configurable file filtering support
spdx30: Add supplier support for image and SDK SBOMs
spdx30: Add ecosystem-specific PURL generation
spdx30: Add version extraction from SRCREV for Git source components
spdx30: Add SPDX_GIT_PURL_MAPPINGS for Git hosting
spdx30: Enrich source downloads with external refs and PURLs
oeqa/selftest: Add test for download_location defensive handling
spdx.py: Add test for version extraction patterns
cve_check: Escape special characters in CPE 2.3 formatted strings

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.

You have extraneous changes that don't belong in this patch set, but
otherwise I'm fine with the addition of SPDX_IMAGE_SUPPLIER and
SPDX_SDK_SUPPLIER

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)

I'm not really a big fan of bb.data.inherits_class. I think it makes
more sense for pypi.bbclass to implement a way to do this behavior and
set the recipe PURL when that class is inherited. Same for the rest of
these, and maybe the GO_IMPORT case above?

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)
- Fallback to SRCREV variable if fd.revision not available
- 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.

I don't really like that this significantly rewrites the
implementation from 2 patches prior; it makes review more difficult.
Is there a reason you did it that way? If not, I'd suggest squashing
the two patches together

This feels like a little too much of a heuristic to me (mapping a tag
to a version); Do we need to do this? The SRCREV seems more precise

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

test_extra_opts has a good reason it doesn't want to pull from the
"normal" sstate; this test doesn't. I'm not sure why this test would
not be able to pull from existing sstate and pass, since you aren't
changing any configuration.

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.

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.

This series enhances SPDX 3.0 SBOM generation with enriched
metadata, ecosystem-specific Package URLs, and compliance
improvements. It addresses all feedback from Joshua Watt's
review of the v7 series.
Changes since v7:
- Patch 1: Dropped tri-state SPDX_FILES_INCLUDED, replaced
with simple SPDX_FILE_EXCLUDE_PATTERNS (no-op when empty).
Removed SBOM_COMPONENT_*/SBOM_SUPPLIER_* variables.
- Patch 2: Cleaned up supplier support, no variable renames.
- Patch 3: Redesigned ecosystem PURL generation. Each bbclass
(pypi, npm, cargo, go-mod, cpan) sets its own PURL by
prepending to SPDX_PACKAGE_URLS. No bb.data.inherits_class()
from SPDX code.
- Patch 4: Squashed v7 patches 4+5+6. Full SHA-1 for versions.
urllib.parse for Git URL parsing. split(':', 1) for mappings.
Extracted _generate_git_purl()/_enrich_source_package().
Dropped tag-to-version heuristic and archive format check.
Preserved inputs.add(dl). HOMEPAGE ref at recipe level only.
- Patch 5: Merged v7 patches 7+8. Dropped SPDX_NAMESPACE_PREFIX
and hasattr() per review feedback.
- Patches 6-7: Unchanged from v7 (LGTM with Reviewed-by).
v7: https://lists.openembedded.org/g/openembedded-core/message/209863
Stefano Tondo (7):
spdx30: Add configurable file exclusion pattern support
spdx30: Add supplier support for image and SDK SBOMs
spdx30: Add ecosystem-specific PURL generation via bbclasses
spdx30: Enrich source downloads with version and PURL
oeqa/selftest: Add tests for source download enrichment
cve_check: Escape special characters in CPE 2.3 strings

Add SPDX_FILE_EXCLUDE_PATTERNS variable that allows filtering files from
SPDX output by pattern matching. The variable accepts a space-separated
list of patterns; files whose paths contain any pattern are excluded.
When empty (the default), no filtering is applied and all files are
included, preserving existing behavior.
This enables users to reduce SBOM size by excluding files that are not
relevant for compliance (e.g., test files, object files, patches).
When file exclusion is active, debug source lookups that reference
filtered files are gracefully skipped instead of causing fatal errors.

"PATTERN" implies regex to me; can we do that (comments below to show
how)? It's a lot more flexible with anchoring, case sensitivity, etc.
e.g.:
SPDX_FILE_EXCLUDE_PATTERNS = "(?i)\\.patch$ (?i)\\.diff$"

Instead of assuming this, have add_package_files also return the list
of excluded files (see above), then pass that into this function for
cross checking (the other callers of add_package_files can just ignore
the excluded files e.g.:
spdx_files, _ = add_package_files(....)

Add SPDX_IMAGE_SUPPLIER and SPDX_SDK_SUPPLIER variables that allow
setting a supplier agent on image and SDK SBOM root elements using
the suppliedBy property.
These follow the existing SPDX_PACKAGE_SUPPLIER pattern and use the
standard agent variable system to define supplier information.

Have each ecosystem bbclass set its own Package URL by prepending to
SPDX_PACKAGE_URLS, rather than detecting inherited classes from the
SPDX code. This follows the principle that each class should know how
to describe itself.
The following bbclasses now generate ecosystem PURLs:
- pypi.bbclass: pkg:pypi/<normalized-name>@PV
- npm.bbclass: pkg:npm/<name>@PV
- cargo_common.bbclass: pkg:cargo/<name>@PV
- go-mod.bbclass: pkg:golang/<GO_IMPORT>@PV
- cpan.bbclass: pkg:cpan/<name>@PV
Additional ecosystems (nuget, maven, dotnet) can follow the same
pattern in their respective layers.

Add version extraction, PURL generation, and external references
to source download packages in SPDX 3.0 SBOMs:
- Extract version from SRCREV for Git sources (full SHA-1)
- Generate PURLs for Git sources on github.com by default
- Support custom mappings via SPDX_GIT_PURL_MAPPINGS variable
(format: "domain:purl_type", split(':', 1) for parsing)
- Use ecosystem PURLs from SPDX_PACKAGE_URLS for non-Git
- Add VCS external references for Git downloads
- Add distribution external references for tarball downloads
- Parse Git URLs using urllib.parse
- Extract logic into _generate_git_purl() and
_enrich_source_package() helpers
The SPDX_GIT_PURL_MAPPINGS variable allows configuring PURL
generation for self-hosted Git services (e.g., GitLab).
github.com is always mapped to pkg:github by default.

Everything else looks OK except for this else block. I'm not sure that
we can reasonably say that the recipe PURL applies to all download
sources, just because they are part of the recipe. _Most_ of the time
this is probably true, but I'm not sure it's the case all the time,
which makes it feel a little dangerous (for example, crates, which I
know you had handled before).

Add two new SPDX 3.0 selftest cases:
test_download_location_defensive_handling:
Verifies SPDX generation succeeds for recipes with tarball sources
and that external references are properly structured (ExternalRef
locator is a list of strings per SPDX 3.0 spec).
test_version_extraction_patterns:
Verifies that version extraction works correctly and all source
packages have proper version strings containing digits.
These tests validate the source download enrichment added in the
previous commit.

CPE 2.3 formatted string binding (cpe:2.3:...) requires
backslash escaping for special meta-characters per NISTIR 7695.
Characters like '++' and ':' in product names must be escaped.
The CPE 2.3 specification defines two bindings:
- URI binding (cpe:/...) uses percent-encoding
- Formatted string (cpe:2.3:...) uses backslash escaping
Escape the required meta-characters with backslash:
- Backslash (\) -> \\
- Question mark (?) -> \?
- Asterisk (*) -> \*
- Colon (:) -> \:
- Plus (+) -> \+
All other characters 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.

This series enhances SPDX 3.0 SBOM generation with enriched
metadata, ecosystem-specific Package URLs, and compliance
improvements.
Changes since v8 (addressing Joshua Watt's review):
1/7: File exclusion now uses re.compile() for proper regex
matching instead of substring matching. Excluded files
are tracked in a set() returned from add_package_files()
and passed to get_package_sources_from_debug() for
precise cross-checking.
2/7: Unchanged (Reviewed-by added).
3/7: Fixed npm_spdx_name() to use bpn[5:] instead of bpn[4:]
since "node-" is 5 characters.
4/7: Dropped PV fallback for non-Git source versions since
the recipe version does not necessarily match individual
downloaded file versions. Ecosystem PURLs (which include
version) from SPDX_PACKAGE_URLS are still used.
5/7: Renamed recipe-m4/recipe-tar to build-m4/build-tar in
tests to align with upstream rename.
6/7: Unchanged (Reviewed-by added).
7/7: Unchanged (Reviewed-by added).
Stefano Tondo (7):
spdx30: Add configurable file exclusion pattern support
spdx30: Add supplier support for image and SDK SBOMs
spdx30: Add ecosystem-specific PURL generation via bbclasses
spdx30: Enrich source downloads with version and PURL
oeqa/selftest: Add tests for source download enrichment
cve_check: Escape special characters in CPE 2.3 strings

Add SPDX_FILE_EXCLUDE_PATTERNS variable that allows filtering files from
SPDX output by regex matching. The variable accepts a space-separated
list of Python regular expressions; files whose paths match any pattern
(via re.search) are excluded.
When empty (the default), no filtering is applied and all files are
included, preserving existing behavior.
This enables users to reduce SBOM size by excluding files that are not
relevant for compliance (e.g., test files, object files, patches).
Excluded files are tracked in a set returned from add_package_files()
and passed to get_package_sources_from_debug(), which uses the set for
precise cross-checking rather than re-evaluating patterns.

Add SPDX_IMAGE_SUPPLIER and SPDX_SDK_SUPPLIER variables that allow
setting a supplier agent on image and SDK SBOM root elements using
the suppliedBy property.
These follow the existing SPDX_PACKAGE_SUPPLIER pattern and use the
standard agent variable system to define supplier information.

Have each ecosystem bbclass set its own Package URL by prepending to
SPDX_PACKAGE_URLS, rather than detecting inherited classes from the
SPDX code. This follows the principle that each class should know how
to describe itself.
The following bbclasses now generate ecosystem PURLs:
- pypi.bbclass: pkg:pypi/<normalized-name>@PV
- npm.bbclass: pkg:npm/<name>@PV
- cargo_common.bbclass: pkg:cargo/<name>@PV
- go-mod.bbclass: pkg:golang/<GO_IMPORT>@PV
- cpan.bbclass: pkg:cpan/<name>@PV
Additional ecosystems (nuget, maven, dotnet) can follow the same
pattern in their respective layers.

Rather than using :prepend, can we just use the =+/+= operators here?
I understand that does introduce ordering constraints but those should
already be handled with spdx being on by default.

Add version extraction, PURL generation, and external references
to source download packages in SPDX 3.0 SBOMs:
- Extract version from SRCREV for Git sources (full SHA-1)
- Generate PURLs for Git sources on github.com by default
- Support custom mappings via SPDX_GIT_PURL_MAPPINGS variable
(format: "domain:purl_type", split(':', 1) for parsing)
- Use ecosystem PURLs from SPDX_PACKAGE_URLS for non-Git
- Add VCS external references for Git downloads
- Add distribution external references for tarball downloads
- Parse Git URLs using urllib.parse
- Extract logic into _generate_git_purl() and
_enrich_source_package() helpers
For non-Git sources, version is not set from PV since the recipe
version does not necessarily reflect the version of individual
downloaded files. Ecosystem PURLs (which include version) from
SPDX_PACKAGE_URLS are still used when available.
The SPDX_GIT_PURL_MAPPINGS variable allows configuring PURL
generation for self-hosted Git services (e.g., GitLab).
github.com is always mapped to pkg:github by default.

Add two new SPDX 3.0 selftest cases:
test_download_location_defensive_handling:
Verifies SPDX generation succeeds for recipes with tarball sources
and that external references are properly structured (ExternalRef
locator is a list of strings per SPDX 3.0 spec).
test_version_extraction_patterns:
Verifies that version extraction works correctly and all source
packages have proper version strings containing digits.
These tests validate the source download enrichment added in the
previous commit.

Looking at the error, I suspect this is to address changes from the
Joshua series, but I didn't had this series in my branch. Is that right?
I will keep these changes in my branch, so we can go further, but please
confirm everything is correct.

Hi Mathieu,
Yes, that's correct, the build-m4/build-tar naming depends on
Joshua's series which renames recipe-* to build-* in the SPDX
output. My series is intended to be applied on top of his.
Once his series lands, these tests should pass.
Thanks,
Stefano

Looking at the error, I suspect this is to address changes from the

I will keep these changes in my branch, so we can go further, but please
confirm everything is correct.
Thanks,

CPE 2.3 formatted string binding (cpe:2.3:...) requires
backslash escaping for special meta-characters per NISTIR 7695.
Characters like '++' and ':' in product names must be escaped.
The CPE 2.3 specification defines two bindings:
- URI binding (cpe:/...) uses percent-encoding
- Formatted string (cpe:2.3:...) uses backslash escaping
Escape the required meta-characters with backslash:
- Backslash (\\) -> \\
- Question mark (?) -> \?
- Asterisk (*) -> \*
- Colon (:) -> \:
- Plus (+) -> \+
All other characters 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.

Add SPDX_FILE_EXCLUDE_PATTERNS variable that allows filtering files from
SPDX output by regex matching. The variable accepts a space-separated
list of Python regular expressions; files whose paths match any pattern
(via re.search) are excluded.
When empty (the default), no filtering is applied and all files are
included, preserving existing behavior.
This enables users to reduce SBOM size by excluding files that are not
relevant for compliance (e.g., test files, object files, patches).
Excluded files are tracked in a set returned from add_package_files()
and passed to get_package_sources_from_debug(), which uses the set for
precise cross-checking rather than re-evaluating patterns.

Add SPDX_IMAGE_SUPPLIER and SPDX_SDK_SUPPLIER variables that allow
setting a supplier agent on image and SDK SBOM root elements using
the suppliedBy property.
These follow the existing SPDX_PACKAGE_SUPPLIER pattern and use the
standard agent variable system to define supplier information.

Add version extraction, PURL generation, and external references
to source download packages in SPDX 3.0 SBOMs:
- Extract version from SRCREV for Git sources (full SHA-1)
- Generate PURLs for Git sources on github.com by default
- Support custom mappings via SPDX_GIT_PURL_MAPPINGS variable
(format: "domain:purl_type", split(':', 1) for parsing)
- Use ecosystem PURLs from SPDX_PACKAGE_URLS for non-Git
- Add VCS external references for Git downloads
- Add distribution external references for tarball downloads
- Parse Git URLs using urllib.parse
- Extract logic into _generate_git_purl() and
_enrich_source_package() helpers
For non-Git sources, version is not set from PV since the recipe
version does not necessarily reflect the version of individual
downloaded files. Ecosystem PURLs (which include version) from
SPDX_PACKAGE_URLS are still used when available.
The SPDX_GIT_PURL_MAPPINGS variable allows configuring PURL
generation for self-hosted Git services (e.g., GitLab).
github.com is always mapped to pkg:github by default.

Add two new SPDX 3.0 selftest cases:
test_download_location_defensive_handling:
Verifies SPDX generation succeeds for recipes with tarball sources
and that external references are properly structured (ExternalRef
locator is a list of strings per SPDX 3.0 spec).
test_version_extraction_patterns:
Verifies that version extraction works correctly and all source
packages have proper version strings containing digits.
These tests validate the source download enrichment added in the
previous commit.

CPE 2.3 formatted string binding (cpe:2.3:...) requires
backslash escaping for special meta-characters per NISTIR 7695.
Characters like '++' and ':' in product names must be escaped.
The CPE 2.3 specification defines two bindings:
- URI binding (cpe:/...) uses percent-encoding
- Formatted string (cpe:2.3:...) uses backslash escaping
Escape the required meta-characters with backslash:
- Backslash (\\) -> \\
- Question mark (?) -> \?
- Asterisk (*) -> \*
- Colon (:) -> \:
- Plus (+) -> \+
All other characters 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.

Thanks for this. I did notice that a couple of these have merged into
master. We also merged Joshua's patches which these ones depend upon in
order for the tests to pass. Could you rebase and resend and hopefully
we can finish getting these merged?
Thanks,
Richard

Hi Stefano,
Joshua series has been merged. I've been trying to rebase this series on
top of it, but I've got a few failures in
spdx.SPDX30Check.test_download_location_defensive_handling and
spdx.SPDX30Check.test_version_extraction_patterns. Either my conflicts
merges were wrong or a few changes are needed.
Can you rebase this series on top of master, make sure the said tests
pass and resend? I believe this is the last step before we can merge it.
Thanks,
Mathieu
