possible missing error handling in hidraw

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

what happens if kmemdup here cannot allocate memory?

	Regards

void hidraw_report_event(struct hid_device *hid, u8 *data, int len)
{
        struct hidraw *dev = hid->hidraw;
        struct hidraw_list *list;

        list_for_each_entry(list, &dev->list, node) {
                list->buffer[list->head].value = kmemdup(data, len, GFP_ATOMIC);
                list->buffer[list->head].len = len;
                list->head = (list->head + 1) & (HIDRAW_BUFFER_SIZE - 1);
                kill_fasync(&list->fasync, SIGIO, POLL_IN);
        }

        wake_up_interruptible(&dev->wait);
}
EXPORT_SYMBOL_GPL(hidraw_report_event);
