* usb: gadget: udc-core: fix the typo of udc state attributeRong Wang2013-08-04
| | | | | | | | | | | | | | commit 1894870eb4240399fabc6f0cb8c6fff4e6edbe83 upstream. The name of udc state attribute file under sysfs is registered as "state", while usb_gadget_set_state take it as "status" when it's going to update. This patch fixes the typo.

* USB: global suspend and remote wakeup don't mixAlan Stern2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit e583d9db9960cf40e0bc8afee4946baa9d71596e upstream. The hub driver was recently changed to use "global" suspend for system suspend transitions on non-SuperSpeed buses. This means that we don't suspend devices individually by setting the suspend feature on the upstream hub port; instead devices all go into suspend automatically when the root hub stops transmitting packets. The idea was to save time and to avoid certain kinds of wakeup races. Now it turns out that many hubs are buggy; they don't relay wakeup requests from a downstream port to their upstream port if the downstream port's suspend feature is not set (depending on the speed of the downstream port, whether or not the hub is enabled for remote wakeup, and possibly other factors). We can't have hubs dropping wakeup requests. Therefore this patch goes partway back to the old policy: It sets the suspend feature for a port if the device attached to that port or any of its descendants is enabled for wakeup. People will still be able to benefit from the time savings if they don't care about wakeup and leave it disabled on all their devices. In order to accomplish this, the patch adds a new field to the usb_hub structure: wakeup_enabled_descendants is a count of how many devices below a suspended hub are enabled for remote wakeup. A corresponding new subroutine determines the number of wakeup-enabled devices at or below an arbitrary suspended USB device. This should be applied to the 3.10 stable kernel.

* usb: dwc3: fix wrong bit mask in dwc3_event_typeHuang Rui2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 1974d494dea05ea227cb42f5e918828801e237aa upstream. Per dwc3 2.50a spec, the is_devspec bit is used to distinguish the Device Endpoint-Specific Event or Device-Specific Event (DEVT). If the bit is 1, the event is represented Device-Specific Event, then use [7:1] bits as Device Specific Event to marked the type. It has 7 bits, and we can see the reserved8_31 variable name which means from 8 to 31 bits marked reserved, actually there are 24 bits not 25 bits between that. And 1 + 7 + 24 = 32, the event size is 4 byes. So in dwc3_event_type, the bit mask should be: is_devspec [0] 1 bit type [7:1] 7 bits reserved8_31 [31:8] 24 bits This patch should be backported to kernels as old as 3.2, that contain the commit 72246da40f3719af3bfd104a2365b32537c27d83 "usb: Introduce DesignWare USB3 DRD Driver".

* xhci: Avoid NULL pointer deref when host dies.Sarah Sharp2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 203a86613fb3bf2767335659513fa98563a3eb71 upstream. When the host controller fails to respond to an Enable Slot command, and the host fails to respond to the register write to abort the command ring, the xHCI driver will assume the host is dead, and call usb_hc_died(). The USB device's slot_id is still set to zero, and the pointer stored at xhci->devs[0] will always be NULL. The call to xhci_check_args in xhci_free_dev should have caught the NULL virt_dev pointer. However, xhci_free_dev is designed to free the xhci_virt_device structures, even if the host is dead, so that we don't leak kernel memory. xhci_free_dev checks the return value from the generic xhci_check_args function. If the return value is -ENODEV, it carries on trying to free the virtual device. The issue is that xhci_check_args looks at the host controller state before it looks at the xhci_virt_device pointer. It will return -ENIVAL because the host is dead, and xhci_free_dev will ignore the return value, and happily dereference the NULL xhci_virt_device pointer. The fix is to make sure that xhci_check_args checks the xhci_virt_device pointer before it checks the host state. See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1203453 for further details. This patch doesn't solve the underlying issue, but will ensure we don't see any more NULL pointer dereferences because of the issue. This patch should be backported to kernels as old as 3.1, that contain the commit 7bd89b4017f46a9b92853940fd9771319acb578a "xhci: Don't submit commands or URBs to halted hosts."

* usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0George Cherian2013-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 07f3cb7c28bf3f4dd80bfb136cf45810c46ac474 upstream. Xhci controllers with hci_version > 0.96 gives spurious success events on short packet completion. During webcam capture the "ERROR Transfer event TRB DMA ptr not part of current TD" was observed. The same application works fine with synopsis controllers hci_version 0.96. The same issue is seen with Intel Pantherpoint xhci controller. So enabling this quirk in xhci_gen_setup if controller verion is greater than 0.96. For xhci-pci move the quirk to much generic place xhci_gen_setup. Note from Sarah: The xHCI 1.0 spec changed how hardware handles short packets. The HW will notify SW of the TRB where the short packet occurred, and it will also give a successful status for the last TRB in a TD (the one with the IOC flag set). On the second successful status, that warning will be triggered in the driver. Software is now supposed to not assume the TD is not completed until it gets that last successful status. That means we have a slight race condition, although it should have little practical impact. This patch papers over that issue. It's on my long-term to-do list to fix this race condition, but it is a much more involved patch that will probably be too big for stable. This patch is needed for stable to avoid serious log spam. This patch should be backported to kernels as old as 3.0, that contain the commit ad808333d8201d53075a11bc8dd83b81f3d68f0b "Intel xhci: Ignore spurious successful event." The patch will have to be modified for kernels older than 3.2, since that kernel added the xhci_gen_setup function for xhci platform devices. The correct conflict resolution for kernels older than 3.2 is to set XHCI_SPURIOUS_SUCCESS in xhci_pci_quirks for all xHCI 1.0 hosts.

* usb: gadget: f_mass_storage: add missing memory barrier for thread_wakeup_neededUCHINO Satoshi2013-07-21
| | | | | | | | | | | | | | | | | | | | | | commit d68c277b501889b3a50c179d1c3d704db7947b83 upstream. Without this memory barrier, the file-storage thread may fail to escape from the following while loop, because it may observe new common->thread_wakeup_needed and old bh->state which are updated by the callback functions. /* Wait for the CBW to arrive */ while (bh->state != BUF_STATE_FULL) { rc = sleep_thread(common); if (rc) return rc; } Signed-off-by: UCHINO Satoshi <satoshi.uchino@toshiba.co.jp> Acked-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* USB: option,qcserial: move Novatel Gobi1K IDs to qcserialDan Williams2013-07-21
| | | | | | | | | | | | commit a254810a86aaaac4ac6ba44fa934558b042a17a7 upstream. These devices are all Gobi1K devices (according to the Windows INF files) and should be handled by qcserial instead of option. Their network port is handled by qmi_wwan.

* USB: option,zte_ev: move most ZTE CDMA devices to zte_evDan Williams2013-06-06
| | | | | | | | | | | | | | Per some ZTE Linux drivers I found for the AC2716, the following patch moves most ZTE CDMA devices from option to zte_ev. The blacklist stuff that option does is not required with zte_ev, because it doesn't implement any of the send_setup hooks which the blacklist suppressed. I did not move the 2718 over because I could not find any ZTE Linux drivers for that device, nor even any Windows drivers.
