From 5ea75095fe6d683900ccc674fcac375e7df68005 Mon Sep 17 00:00:00 2001 From: Pali Rohár Date: Mon, 8 Jun 2015 08:20:05 +0200 Subject: usb: gadget: nokia: Add mass storage driver to g_nokia MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds removable mass storage support to g_nokia gadget (for N900). It means that at runtime block device can be exported or unexported. So it does not export anything by default and thus allows to use MyDocs partition as before...

This flag is used when creating and freeing luns. Unfortunately there is no guarantee that this flag will not be changed between creation and removal of particular LUN. Especially because of lun.0 which is created during allocating instance of function.

However, rx_complete() in f_printer.c calls spinlock on printer_dev->lock again, which will cause system hang. The following steps can reproduce this hang: 1. Build the test program from Documentation/usb/gadget_printer.txt as g_printer 2. Plug in the USB device to a host(such as Ubuntu). 3. on the USB device system run: #modprobe g_printer.ko #./g_printer -read_data 4. Unplug the USB device from the host The system will hang later. In order to avoid this deadlock, moving the spinlock from printer_func_disable() into printer_reset_interface() and excluding the block of calling dwc3_gadget_ep_disable(), in which the critical resource will be protected by its spinlock in rx_complete().

It could cause bugs because if some function doesn't set this field autoconfig could return the same endpoint more than one time. To help to avoid such bugs this patch adds claimed flag to struct usb_ep, and encapsulates endpoint claiming mechanism inside usb_ep_autoconfig_ss() and usb_ep_autoconfig_reset(), so now usb functions don't need to perform any additional actions to mark endpoint obtained from autoconfig as claimed.
