Worked on enhancing memory safety in the nanvix/nanvix repository by developing a targeted test for mmap zero-initialization. The contribution focused on verifying that memory pages allocated through mmap are properly initialized with zeros and that remapping operations clear any previously written data, ensuring deterministic and safe memory behavior. This involved implementing a dedicated test function that also checked the correct acquisition and release of memory management capabilities. Utilizing Rust and leveraging skills in memory management, system programming, and testing, the work reinforced the reliability of the memory subsystem and improved the predictability of memory operations within the project’s codebase.
