* USB: f_mass_storage: 2048 block size for cdrom devicesFrozenCow2013-03-032-10/+16
| | | | | | | | | | Bios will recognize the cdrom device like most other cdrom devices. This allows people to boot ISOs from their phone. Original by Andreas Kemnade: http://www.spinics.net/lists/linux-usb/msg25178.html Change-Id: Id8fba96e1683f6daa6330b1e59f4a4ca4fe5c271

| * usb: gadget: dummy: fix enumeration with g_multiSebastian Andrzej Siewior2013-01-171-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 1d16638e3b9cc195bac18a8fcbca748f33c1bc24 upstream. If we do have endpoints named like "ep-a" then bEndpointAddress is counted internally by the gadget framework. If we do have endpoints named like "ep-1" then bEndpointAddress is assigned from the digit after "ep-". If we do have both, then it is likely that after we used up the "generic" endpoints we will use the digits and thus assign one bEndpointAddress to multiple endpoints. This theory can be proofed by using the completely enabled g_multi. Without this patch, the mass storage won't enumerate and times out because it shares endpoints with RNDIS. This patch also adds fills up the endpoints list so we have in total endpoints 1 to 15 in + out available while some of them are restricted to certain types like BULK or ISO. Without this change the nokia gadget won't load because the system does not provide enough (BULK) endpoints but it did before ep-a - ep-f were removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 31bde1ceaa873bcaecd49e829bfabceacc4c512d upstream. A "usb0" interface that has never been connected to a host has an unknown operstate, and therefore the IFF_RUNNING flag is (incorrectly) asserted when queried by ifconfig, ifplugd, etc. This is a result of calling netif_carrier_off() too early in the probe function; it should be called after register_netdev(). Similar problems have been fixed in many other drivers, e.g.: e826eafa6 (bonding: Call netif_carrier_off after register_netdevice) 0d672e9f8 (drivers/net: Call netif_carrier_off at the end of the probe) 6a3c869a6 (cxgb4: fix reported state of interfaces without link) Fix is to move netif_carrier_off() to the end of the function.

| * usb: gadget: fsl_udc_core: dTD's next dtd pointer need to be updated once ↵Peter Chen2012-06-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | written commit 4d0947dec4db1224354e2f6f00ae22ce38e62a43 upstream. dTD's next dtd pointer need to be updated once CPU writes it, or this request may not be handled by controller, then host will get NAK from device forever. This problem occurs when there is a request is handling, we need to add a new request to dTD list, if this new request is added before the current one is finished, the new request is intended to added as next dtd pointer at current dTD, but without wmb(), the dTD's next dtd pointer may not be updated when the controller reads it. In that case, the controller will still get Terminate Bit is 1 at dTD's next dtd pointer, that means there is no next request, then this new request is missed by controller.

This patch (as1539) fixes a minor bug in the mass-storage gadget drivers. When an unknown command is received, the error code sent back is "Invalid Field in CDB" rather than "Invalid Command". This is because the bitmask of CDB bytes allowed to be nonzero is incorrect. When handling an unknown command, we don't care which command bytes are nonzero. All the bits in the mask should be set, not just eight of them.

To fix this problem, below changes are made: - fsl_req_to_dtd doesn't need to be protected by spin_lock_irqsave, as struct usb_request can be access at process context. Move lock to beginning of hardware visit (fsl_queue_td). - Change the memory flag which using to allocate dTD descriptor buffer, the memory flag can be from gadget layer. It is tested at i.mx51 bbg board with g_mass_storage, g_ether, g_serial.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 85b4b3c8c189e0159101f7628a71411af072ff69 upstream. A read from GadgetFS endpoint 0 during the data stage of a control request would always return 0 on success (as returned by wait_event_interruptible) despite having written data into the user buffer. This patch makes it correctly set the return value to the number of bytes read. Signed-off-by: Thomas Faber <thfabba@gmx.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
