Investigated and fixed a bug in OpenBSD’s memory sharing implementation while working within an unfamiliar production kernel codebase.
- Reproduced and documented incorrect behaviour in the kernel’s memory sharing logic.
- Traced the issue through the relevant memory-management code with guidance from course tutors.
- Implemented and tested a patch that corrected the underlying behaviour.
- Submitted the fix upstream, where it was reviewed and incorporated into OpenBSD.
