Run the native checkers through the ordered SCST module build with C=2.
Preserve Kbuild flags, full raw output and every attempted CHECK record.
Keep full, diff and explicit input selection on the shared scope; diff
selection triggers the complete configured module analysis.
Read exact diagnostic exceptions from policy/sparse.json and
smatch.json: two reviewed Smatch IRQ reports and the external FC
flexible-array warning. Keep the existing SCST matching boundaries and
reasons. Smatch uses its matching installed kernel data without
engine-specific additions.
Reject build, checker, frontend and truncation failures even when Kbuild
returns success. Retain per-invocation records and a machine-readable
run summary, and detect printed CHECK steps without a record. Require
selected C inputs to occur in the build. Keep findings distinct from
incompleteness.
Check native compatibility before compilation, and forward external
kernel capability probes to the real checker instead of skipping them as
inputs outside SCST. Include the pinned Smatch typeof frontend
correction and isolated fixtures for failure propagation and exact
exception boundaries.
Move the source roots, file types and input exclusions from lint_scope.py
into policy/common.json. Keep the existing scope, including KUnit sources,
the newer QLogic target and the exclusions for the legacy QLogic tree,
upstream QLogic sources, compiler probes and generated module metadata.
Adapt engine's reviewed-data and strict-loader approach to SCST. Require
reasons for input exclusions and reject malformed, missing or ambiguous
policy before selecting files. Do not import engine's exclusions or add
environment-based filtering or diagnostic suppression.
Use this policy for full, diff and explicit-file selection. Preserve both
lexical and resolved path checks, single-commit diff bases and index-based
selection. Treat policy paths literally in Git pathspecs as well as Python.
Add isolated fixtures for schema failures and policy-driven selection.
Passing the base directly to git diff allows an option such as --quiet to
be interpreted as a flag. On a clean worktree it can succeed without
selecting any sources, instead of rejecting the invalid revision.
Resolve the base with rev-parse --verify --end-of-options and require a
commit before building the diff command. Reuse the resulting object ID so
options, ranges, tree objects and unknown revisions cannot turn an invalid
request into an empty selection.
Add a fixture covering rejected bases on a clean tree and a valid tag
before and after a source change. Expose the resolver for future patch
consumers as well.
Give the upcoming analyzer drivers one source-selection policy for full,
working-tree diff and explicit-file checks. Include product C sources and
headers, including KUnit, and keep both lexical and resolved paths within
the allowed directories.
Select only the newer QLogic SCST target directory. Exclude the legacy
QLogic tree, the upstream part of the newer driver, the two conftest trees
and generated .mod.c files. Document these input exclusions separately
from diagnostic filtering, which this helper does not perform.
Add temporary-repository fixtures and a make lint-test entry point. Keep
the existing checkpatch and kernel regression consumers unchanged until
their replacement drivers are introduced.
