Oliver Neukum 69626f23bc HID: fix race between open() and disconnect() in usbhid ... There is a window: task A task B spin_lock_irq(&usbhid->inlock); /* Sync with error handler */ usb_set_intfdata(intf, NULL); spin_unlock_irq(&usbhid->inlock); usb_kill_urb(usbhid->urbin); usb_kill_urb(usbhid->urbout); usb_kill_urb(usbhid->urbctrl); del_timer_sync(&usbhid->io_retry); cancel_work_sync(&usbhid->reset_work); if (!hid->open++) { res = usb_autopm_get_interface(usbhid->intf); if (res < 0) { hid->open--; return -EIO; } } if (hid_start_in(hid)) if (hid->claimed & HID_CLAIMED_INPUT) hidinput_disconnect(hid); in which an open() to an already disconnected device will submit an URB to an undead device. In case disconnect() was called by an ioctl, this'll oops. Fix by introducing a new flag and checking it in hid_start_in().
