Adds a custom CodeQL query (.github/codeql/openssl-return-check.ql) that detects calls to OpenSSL EVP_* functions whose return value is not guarded by the OQS_OPENSSL_GUARD macro. Integrates the query into a new CodeQL workflow (.github/workflows/codeql.yml) that runs on every PR and push to main. The query was originally written by Trail of Bits during their audit of liboqs and reported in issue open-quantum-safe#1867.

Addresses Scorecard Token-Permissions finding: security-events write permission scoped to codeql job only, not workflow level. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>
Replace inline queries: path with a codeql-config.yml config file. The CodeQL init action requires local queries to be referenced via a config file rather than a direct relative path in the queries field. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>
The CodeQL cpp extractor pre-finalize script crashes with exit code 134 when the trapCaches/cpp/tarballs directory does not exist on the runner. Disabling TRAP caching avoids the crash. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>
Replace config-file approach with inline queries field combining security-and-quality suite with the custom EVP return check query, as suggested by @baentsch. Remove codeql-config.yml. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>

Adding upload: false to the analyze step prevents the SARIF conflict with GitHub's default CodeQL setup which is enabled on this repo. The query still runs and catches issues but does not upload results. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>
Add bad example at .github/codeql/test/openssl-return-check-bad.c to confirm the query catches unchecked EVP_* calls. Document verification steps in CONTRIBUTING.md. Signed-off-by: Vishnu Ajith <27vishnu07@gmail.com>

Address the review concerns from open-quantum-safe#2415: - Do not upload results to code scanning, which rejects CodeQL results from other workflows while default setup is enabled. Instead, print each result as an error annotation and fail the job if there are any - Run only liboqs's own queries, since the standard suite already runs via default setup. - Add CodeQL unit tests for each query which run in a seperate job - Analyse a full default build with OpenSSL used for AES, SHA2 and SHA3 - Flag only EVP_* calls whose return value is discarded, since there are other safe ways beyond OQS_OPENSSL_GUARD to check this. - In pr.yml, depend on check-push-result rather than basic-checks and drop `security-events: write`, so the job can be run in forks. The workflow currently reports 119 unchecked EVP_* calls in src/common. These will be fixed separately. Assisted-by: Claude:claude-opus-5.5 Signed-off-by: Owen Waldron <owen.waldron@uwaterloo.ca>

Demo, not for merge. Shows how a CodeQL custom-query finding appears inline on a pull request.
The branch is the CodeQL workflow rework with the
EVP_*fixes, plus:TEST ONLYcommit that trimspr.ymlto just the CodeQL job (and skipspush.ymlfor this branch), so no other CI runs;DEMOcommit that removes oneOQS_OPENSSL_GUARDinsrc/common/sha3/ossl_sha3.c.Expected outcome:
CodeQL custom queriesfails with exactly one result,ossl_sha3.c:20, shown as an error annotation on that line under "Files changed".🤖 Generated with Claude Code
