Worked on the DragonOS-Community/DragonOS repository to deliver configurable asynchronous I/O signal notifications, enabling userspace to specify which signal is delivered for async I/O on pipes and sockets. Implemented F_SETSIG and F_GETSIG fcntl commands in Rust, introducing per-file fasync_signum with validation against SIGRTMAX and ensuring correct signal preservation across process clones. Integrated these changes into the fasync delivery path, updating event semantics and close handling to align with Linux system programming standards. Expanded end-to-end test coverage using dunitest to verify default behaviors, round-trip correctness, boundary conditions, and error handling for invalid file descriptors, improving reliability and control.

May 1, 2026May 2026 performance summary for DragonOS-Community/DragonOS. Delivered configurable async I/O notification control via F_SETSIG/F_GETSIG, enabling userspace to specify the signal delivered for asynchronous I/O on pipes and sockets. Implemented per-file fasync_signum (AtomicI32) with validation against SIGRTMAX and preservation across clone, and wired this into the fasync delivery path. Extended signal mapping and event semantics to align with Linux behavior, including close-event handling for pipes and sockets. Added end-to-end tests (fcntl_signal dunitest) covering defaults, get/set round-trips, SIGRTMAX boundary, and invalid file descriptors.
