feat(file-system): implement read and write FAT32 File System and basic shell2026-01-04T06:05:49ZRichard Qinrichard.qin.x@gmail.com2026-01-04T06:05:49Zurn:sha1:d3cf3f08d1343d6b265516d5a79ce2d197b59d26Fix: critical malloc size calculation bug2026-01-02T18:13:08ZRichard Qinrichard.qin.x@gmail.com2026-01-02T18:13:08Zurn:sha1:10614e04929a6d109a5e90524e446b637aaf0c13
Summary:
- Fixed an integer arithmetic error in malloc() where 'nunits' was initialized to 0, causing incorrect heap sizing.
- This bug caused malloc to return pointers pointing to unmapped memory pages, leading to Store Page Fault (scause 15) at process boundaries.
- Switched memory allocator logic to use byte-based size calculation instead of K&R style units to prevent off-by-one errors.
Improvements:
- Shell now starts successfully without segfaults.
