Function sys_socket 

pub fn sys_socket(abi: &mut LinuxRiscv64Abi, trapframe: &mut Trapframe) -> usize

Linux sys_socket implementation

Creates a socket endpoint for communication. Now properly integrated with NetworkManager and VFS for Unix domain socket support.

Arguments:

• abi: LinuxRiscv64Abi context
• trapframe: Trapframe containing syscall arguments
  • arg0: domain (communication domain, e.g., AF_UNIX, AF_INET)
  • arg1: type (socket type, e.g., SOCK_STREAM, SOCK_DGRAM)
  • arg2: protocol (protocol to use, usually 0)

Returns:

• file descriptor on success
• usize::MAX (Linux -1) on error
