  • I added a separate CI workflow/build job for ModSecurity v3 to make compiler warnings and hardening-related issues visible earlier in the development process.
  • The job intentionally builds ModSecurity with stricter GCC warning flags such as -Wall, -Wextra, -Wformat, and -Wformat-security.
  • The run currently operates in a warn-only mode so existing warnings become visible in CI without immediately failing the entire workflow because of -Werror.
  • This helps detect potential issues and regressions early and allows them to be fixed proactively before they appear in Fedora/RHEL packaging or downstream builds.
  • In addition, all relevant compiler, linker, and configure flags are printed in the CI logs to improve transparency and reproducibility of the build environment.
  • The long-term goal is to continuously reduce warnings and hardening issues and eventually re-enable stricter error handling (-Werror).

#3567

Summary by CodeRabbit

  • Chores
    • Added an automated ModSecurity v3 build check on Ubuntu 24.04. The check prepares build dependencies, configures compiler and linker settings, enables assertions, and runs a parallel build. It also detects an available Lua development package and reports an error if a suitable package cannot be determined.

Pull request overview

Adds an additional CI job intended to surface GCC warnings and common hardening-related build issues for ModSecurity v3 earlier in the development cycle, while keeping the job “warn-only” to avoid immediately breaking CI.

Changes:

  • Introduces a new “ModSecurity v3 (warn-only hardening build)” job on Ubuntu 24.04.
  • Builds with stricter compiler/linker flags and prints toolchain + build flag configuration to CI logs.
  • Auto-detects and installs the latest libluaX.Y-dev package before building.

📝 Walkthrough

Walkthrough

Adds a GitHub Actions job on Ubuntu 24.04 to build ModSecurity v3. The job checks out recursive submodules, selects a Lua development package, installs build dependencies, sets compiler and linker flags, and runs configuration and build commands.

Changes

ModSecurity v3 CI build

Layer / File(s) Summary
Prepare the build environment
.github/workflows/ci_new.yml
Adds an Ubuntu 24.04 job with recursive checkout. It selects the highest available libluaX.Y-dev package, installs build dependencies, and runs build.sh.
Configure and run the build
.github/workflows/ci_new.yml
Sets compiler and linker flags, removes -Werror and -Werror=format-security when MODSECURITY_WARN_ONLY is 1, reports build settings, enables assertions, and runs a verbose parallel build.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: 🔵 Low · up to bf50b

This adds a CI-only build job. The checkout step should disable credential persistence, per project guidance, before merge. Otherwise the change has low risk.

Security Architecture Review

Security architecture risk: 🔵 Low · up to bf50b

The new hardening build repeats an existing CI execution pattern rather than introducing broader privileges or production access. Checkout credential exposure remains relevant, and effective token permissions are unknown, so the change cannot be assessed as minimal risk.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — Credential misuse would be bounded by the job token's effective permissions to repository-associated resources. The new job adds another execution instance, but the comparison establishes no new credential class, broader privilege grant, or production target. The permission-dependent maximum exposure remains unresolved.

Security Findings and Attack Paths

  • observed — The retained reportable finding concerns persisted checkout credentials exposed to repository-controlled build execution. An actor able to influence checked-out build code can execute that code after checkout. The same path existed in the base Linux job, so the finding remains relevant without establishing that this PR introduced or materially worsened it.

Trust Boundaries and Controls

  • inferred — The critical boundary is repository-controlled code executing in a credential-bearing CI job. The pull_request trigger and absence of explicit secret injection are counterevidence against an inherently privileged fork-PR path. They do not establish the effective authority of fork PRs, same-repository PRs, or pushes; repository and organization settings are still needed.

Resilience and Maintainability Implications

  • inferred — The workflow delegates credential cleanup and execution isolation to checkout and the runner platform. Available source does not verify terminal behavior after failure, cancellation, interruption, retries, or concurrent runs. Cleanup after execution would not prevent credential access during the build itself.

Hardening Proposals

  • proposed — Declare the minimum required token permissions and disable checkout credential persistence where later authenticated Git operations are unnecessary. Apply the policy consistently to existing build jobs as well as the new job, and verify event-specific permissions and abnormal-termination cleanup.
