PROFILE
Mickaël Salaün
Mic contributed to the google/syzkaller repository by developing and enhancing security features and test reliability for the Linux kernel’s Landlock module. Over two months, Mic implemented new audit and execution-logging flags in C and Shell, enabling finer-grained policy enforcement and improved observability for container isolation. The work included updating documentation and refining system programming interfaces to support these features. Additionally, Mic improved the Landlock test suite by removing unnecessary setuid sandbox restrictions, fixing device handling in IOCTL tests, and aligning ptrace error codes. These changes deepened kernel security integration and strengthened automated testing reliability for Landlock scenarios.

Jul 1, 2025For 2025-07, delivered focused Landlock test-suite reliability improvements in google/syzkaller. The changes reduce flakiness and improve correctness by removing unnecessary setuid sandbox restrictions in Landlock tests, fixing landlock_fs_ioctl by creating a proper /dev/null device and valid IOCTL, and aligning ptrace error codes across threads to match expectations. These updates strengthen test stability, accelerate CI feedback for kernel testing, and improve coverage for Landlock scenarios.

Feb 1, 2025February 2025 monthly summary for google/syzkaller: Delivered new Landlock audit and execution-logging flags to enhance policy enforcement and observability in the Landlock security module. Updated related documentation (landlock_create_ruleset and landlock_restrict_self) to reflect the new flags, enabling finer-grained security policy enforcement for container isolation. While there were no major bug fixes recorded in this period, the feature-focused work strengthens security posture, policy visibility, and governance. This initiative aligns with broader kernel security goals and improves developer feedback loops for policy debugging and auditing.
