From: Geliang Tang The server file descriptor ('fd') is opened in server() but never closed. While accepted connections are properly closed in process_one_client(), the main listening socket remains open, causing a resource leak. This patch ensures the server fd is properly closed after processing clients, bringing the sockopt and inq test cases in line with proper resource cleanup practices.
