2013-08-26USB: OHCI: fix build error related to ohci_suspend/resumeAlan Stern1-0/+2
Commit 9a11899c5e69 (USB: OHCI: add missing PCI PM callbacks to ohci-pci.c) added missing ohci_suspend and ohci_resume callback pointers, but forgot that these callbacks are declared and defined only when CONFIG_PM is enabled. This patch adds a preprocessor conditional to avoid build errors when PM is disabled.

2013-08-12wusbcore: fix kernel panic when disconnecting a wireless USB->serial deviceThomas Pugliese1-2/+7
This patch fixes a kernel panic that can occur when disconnecting a wireless USB->serial device. When the serial device disconnects, the device cleanup procedure ends up calling usb_hcd_disable_endpoint on the serial device's endpoints. The wusbcore uses the ABORT_RPIPE command to abort all transfers on the given endpoint but it does not properly give back the URBs when the transfer results return from the HWA. This patch prevents the transfer result processing code from bailing out when it sees a WA_XFER_STATUS_ABORTED result code so that these urbs are flushed properly by usb_hcd_disable_endpoint. It also updates wa_urb_dequeue to handle the case where the endpoint has already been cleaned up when usb_kill_urb is called which is where the panic originally occurred.

2013-08-12USB: EHCI: accept very late isochronous URBsAlan Stern1-7/+6
Since commits 4005ad4390bf (EHCI: implement new semantics for URB_ISO_ASAP) and c75c5ab575af (ALSA: USB: adjust for changed 3.8 USB API) became widely distributed, people have been experiencing problems with audio transfers. The slightest underrun causes complete failure, requiring the audio stream to be restarted. It turns out that the current isochronous API doesn't handle underruns in the best way. The ALSA developers would much rather have transfers that are submitted too late be accepted and complete in the normal fashion, rather than being refused outright. This patch implements the requested approach. When an isochronous URB submission is so late that all its scheduled slots have already expired, a debugging message will be printed in the log and the URB will be accepted as usual. Assuming it was submitted by a completion handler (which is normally the case), it will complete shortly thereafter with all the usb_iso_packet_descriptor status fields marked -EXDEV. This fixes (for ehci-hcd) https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1191603 It should be applied to all kernels that include commit 4005ad4390bf.

2013-07-31usb: core: don't try to reset_device() a port that got just disconnectedJulius Werner1-2/+3
The USB hub driver's event handler contains a check to catch SuperSpeed devices that transitioned into the SS.Inactive state and tries to fix them with a reset. It decides whether to do a plain hub port reset or call the usb_reset_device() function based on whether there was a device attached to the port. However, there are device/hub combinations (found with a JetFlash Transcend mass storage stick (8564:1000) on the root hub of an Intel LynxPoint PCH) which can transition to the SS.Inactive state on disconnect (and stay there long enough for the host to notice). In this case, above-mentioned reset check will call usb_reset_device() on the stale device data structure. The kernel will send pointless LPM control messages to the no longer connected device address and can even cause several 5 second khubd stalls on some (buggy?) host controllers, before finally accepting the device's fate amongst a flurry of error messages. This patch makes the choice of reset dependent on the port status that has just been read from the hub in addition to the existence of an in-kernel data structure for the device, and only proceeds with the more extensive reset if both are valid.

in some cases where device is attched to xhci port and do not responding, for example ath9k_htc with stalled firmware, kernel will crash on ring_doorbell_for_active_rings. This patch check if pointer exist before it is used.

2013-07-25usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0George Cherian2-1/+7
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.

2013-07-25usb: xhci: Mark two functions __maybe_unusedOlof Johansson1-2/+2
Resolves the following build warnings: drivers/usb/host/xhci.c:332:13: warning: 'xhci_msix_sync_irqs' defined but not used [-Wunused-function] drivers/usb/host/xhci.c:3901:12: warning: 'xhci_change_max_exit_latency' defined but not used [-Wunused-function] These functions are not always used, and since they're marked static they will produce build warnings: - xhci_msix_sync_irqs is only used with CONFIG_PCI. - xhci_change_max_exit_latency is a little more complicated with dependencies on CONFIG_PM and CONFIG_PM_RUNTIME. Instead of building a bigger maze of ifdefs in this code, I've just marked both with __maybe_unused.

2013-07-25xhci: Avoid NULL pointer deref when host dies.Sarah Sharp1-3/+3
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."

2013-07-24USB: ti_usb_3410_5052: fix dynamic-id matchingJohan Hovold1-1/+1
The driver failed to take the dynamic ids into account when determining the device type and therefore all devices were detected as 2-port devices when using the dynamic-id interface. Match on the usb-serial-driver field instead of doing redundant id-table searches.

2013-07-22USB: EHCI: Fix resume signalling on remote wakeupRoger Quadros1-0/+1
Set the ehci->resuming flag for the port we receive a remote wakeup on so that resume signalling can be completed. Without this, the root hub timer will not fire again to check if the resume was completed and there will be a never-ending wait on on the port. This effect is only observed if the HUB IRQ IN does not come after we have initiated the port resume.

This patch was tested on 3.10.1 kernel. Same models of Petatel NP10T modems have different device IDs. Unfortunately they have no additional revision information on a board which may treat them as different devices. Currently I've seen only two NP10T devices with various IDs. Possibly Petatel NP10T list will be appended upon devices with new IDs will appear.
