PROFILE
Brooks Davis
Brooks worked on the CTSRD-CHERI/cheribsd repository, focusing on system-level improvements in C and Makefile to enhance memory safety, build reliability, and runtime correctness. He refactored the NVI Editor’s buffer realignment to use memmove, eliminating out-of-bounds reads and improving stability for CheriBSD users. Brooks also addressed realpath syscall handling by aligning symbol usage and removing legacy kernel support, which improved maintainability and correctness. In addition, he delivered build system enhancements, clarified documentation, and updated the runtime linker to use libsys syscall implementations. His work demonstrated depth in buffer manipulation, build system configuration, and low-level system programming.

Feb 1, 2025February 2025 was focused on delivering a high-impact bug fix to realpath syscall handling to ensure correctness, maintainability, and alignment with CheriBSD changes. The work targeted the realpath implementation in CheriBSD, correcting syscall symbol usage and eliminating exposure of internal symbols to external libraries. This reduces risk of incorrect syscall stubs and improves reliability for users of realpath(3) across updated kernels.
