Over seven months, contributed to the DragonOS-Community/DragonOS repository by building and refining core kernel and filesystem features using Rust, Shell, and Makefile. Delivered enhancements such as clone3 and get_mempolicy system calls, VFS API refactoring, and virtio-vsock support to improve process management, memory handling, and virtualization. Addressed reliability through targeted bug fixes in memory allocators, TTY, and NTty drivers, while implementing security best practices like SHA-512 password hashing. Focused on maintainability and performance, the work included file readahead, page cache improvements, and robust error handling, resulting in a more stable, secure, and extensible system programming foundation.

Mar 1, 2026March 2026 highlights: Delivered foundational Virtio-vsock support enabling AF_VSOCK-based local and remote communication within DragonOS, including a virtio-vsock PCI driver and a new vsock transport abstraction. Extended QEMU device management with vhost-vsock integration and CID handling, enabling streamlined virtualization workflows. Implemented user-space testing utilities to verify vsock functionality end-to-end, improving reliability and developer confidence. Improved memory safety and performance through enhanced DMA bounce buffer handling in the virtio HAL for non-direct-mapped addresses. Fixed critical write syscall reliability by strengthening user buffer handling and error checking, boosting data integrity and security.
