[PATCH] usb: Patch for USBDEVFS_IOCTL from 32-bit programs
Dell supplied me with the following test: #include<stdio.h> #include<errno.h> #include<sys/ioctl.h> #include<fcntl.h> #include<linux/usbdevice_fs.h> main(int argc,char*argv[]) { struct usbdevfs_hub_portinfo hubPortInfo = {0}; struct usbdevfs_ioctl command = {0}; command.ifno = 0; command.ioctl_code = USBDEVFS_HUB_PORTINFO; command.data = (void*)&hubPortInfo; int fd, ret; if(argc != 2) { fprintf(stderr,"Usage: %s /proc/bus/usb/<BusNo>/<HubID>\n",argv[0]); fprintf(stderr,"Example: %s /proc/bus/usb/001/001\n",argv[0]); exit(1); } errno = 0; fd = open(argv[1],O_RDWR); if(fd < 0) { perror("open failed:"); exit(errno); } errno = 0; ret = ioctl(fd,USBDEVFS_IOCTL,&command); printf("IOCTL return status:%d\n",ret); if(ret<0) { perror("IOCTL failed:"); close(fd); exit(3); } else { printf("IOCTL passed:Num of ports %d\n",hubPortInfo.nports); close(fd); exit(0); } return 0; } I have verified that it breaks if built in 32 bit mode on x86_64 and that the patch below fixes it.
