In linux, ioctl command number has a 32-bit unsigned integer type: fs/ioctl.c:SYSCALL_DEFINE3(ioctl, unsigned int, fd, unsigned int, cmd, unsigned long, arg) If the kernel completely ignores other bits on 64-bit architectures, why should strace care? Let's follow the kernel and treat it as unsigned int. * defs.h (struct_ioctlent): Change "code" type to "unsigned int". (ioctl_decode, ioctl_lookup, block_ioctl, loop_ioctl, mtd_ioctl, ubi_ioctl, ptp_ioctl, scsi_ioctl, sock_ioctl, term_ioctl, rtc_ioctl, v4l2_ioctl): Likewise. * ioctl.c (ioctl_decode, ioctl_lookup, compare, ioctl_next_match): Likewise. * block.c (block_ioctl): Likewise. * loop.c (loop_ioctl): Likewise. * mtd.c (mtd_ioctl, ubi_ioctl): Likewise. * ptp.c (ptp_ioctl): Likewise. * scsi.c (scsi_ioctl): Likewise. * sock.c (sock_ioctl): Likewise. * term.c (term_ioctl): Likewise. * time.c (rtc_ioctl): Likewise. * v4l2.c (v4l2_ioctl): Likewise. * ioctlsort.c (struct ioctlent, compare, main): Likewise.
