2016-02-27xhci: Fix list corruption in urb dequeue at host removalMathias Nyman1-1/+3
commit 5c82171167adb8e4ac77b91a42cd49fb211a81a0 upstream. xhci driver frees data for all devices, both usb2 and and usb3 the first time usb_remove_hcd() is called, including td_list and and xhci_ring structures. When usb_remove_hcd() is called a second time for the second xhci bus it will try to dequeue all pending urbs, and touches td_list which is already freed for that endpoint.

2016-02-27Revert "xhci: don't finish a TD if we get a short-transfer event mid TD"Mathias Nyman1-10/+0
commit a6835090716a85f2297668ba593bd00e1051e662 upstream. This reverts commit e210c422b6fd ("xhci: don't finish a TD if we get a short transfer event mid TD") Turns out that most host controllers do not follow the xHCI specs and never send the second event for the last TRB in the TD if there was a short event mid-TD. Returning the URB directly after the first short-transfer event is far better than never returning the URB. (class drivers usually timeout after 30sec). For the hosts that do send the second event we will go back to treating it as misplaced event and print an error message for it. The origial patch was sent to stable kernels and needs to be reverted from there as well Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> [bwh: Backported to 3.2: adjust context] Signed-off-by: Ben Hutchings <ben@decadent.org.uk>

2016-01-23USB: fix invalid memory access in hub_activate()Alan Stern1-4/+20
commit e50293ef9775c5f1cf3fcc093037dd6a8c5684ea upstream. Commit 8520f38099cc ("USB: change hub initialization sleeps to delayed_work") changed the hub_activate() routine to make part of it run in a workqueue. However, the commit failed to take a reference to the usb_hub structure or to lock the hub interface while doing so. As a result, if a hub is plugged in and quickly unplugged before the work routine can run, the routine will try to access memory that has been deallocated. Or, if the hub is unplugged while the routine is running, the memory may be deallocated while it is in active use. This patch fixes the problem by taking a reference to the usb_hub at the start of hub_activate() and releasing it at the end (when the work is finished), and by locking the hub interface while the work routine is running. It also adds a check at the start of the routine to see if the hub has already been disconnected, in which nothing should be done.

2015-12-30USB: cdc_acm: Ignore Infineon Flash Loader utilityJonas Jonsson1-0/+5
commit f33a7f72e5fc033daccbb8d4753d7c5c41a4d67b upstream. Some modems, such as the Telit UE910, are using an Infineon Flash Loader utility. It has two interfaces, 2/2/0 (Abstract Modem) and 10/0/0 (CDC Data). The latter can be used as a serial interface to upgrade the firmware of the modem. However, that isn't possible when the cdc-acm driver takes control of the device. The following is an explanation of the behaviour by Daniele Palmas during discussion on linux-usb. "This is what happens when the device is turned on (without modifying the drivers): [155492.352031] usb 1-3: new high-speed USB device number 27 using ehci-pci [155492.485429] usb 1-3: config 1 interface 0 altsetting 0 endpoint 0x81 has an invalid bInterval 255, changing to 11 [155492.485436] usb 1-3: New USB device found, idVendor=058b, idProduct=0041 [155492.485439] usb 1-3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [155492.485952] cdc_acm 1-3:1.0: ttyACM0: USB ACM device This is the flashing device that is caught by the cdc-acm driver. Once the ttyACM appears, the application starts sending a magic string (simple write on the file descriptor) to keep the device in flashing mode.

2015-12-30xhci: Workaround to get Intel xHCI reset working more reliablyRajmohan Mani1-0/+10
commit a5964396190d0c40dd549c23848c282fffa5d1f2 upstream. Existing Intel xHCI controllers require a delay of 1 mS, after setting the CMD_RESET bit in command register, before accessing any HC registers. This allows the HC to complete the reset operation and be ready for HC register access. Without this delay, the subsequent HC register access, may result in a system hang, very rarely. Verified CherryView / Braswell platforms go through over 5000 warm reboot cycles (which was not possible without this patch), without any xHCI reset hang.

commit 705e63d2b29c8bbf091119084544d353bda70393 upstream. There is a bit of a mess in the order of arguments to the ulpi write callback. There is int ulpi_write(struct ulpi *ulpi, u8 addr, u8 val) in drivers/usb/common/ulpi.c; struct usb_phy_io_ops { ... int (*write)(struct usb_phy *x, u32 val, u32 reg); } in include/linux/usb/phy.h. The callback registered by the musb driver has to comply to the latter, but up to now had "offset" first which effectively made the function broken for correct users.

The device is modeswitched from 1410:9020 to 1410:9022 by selecting the 4th USB configuration: $ sudo usb_modeswitch –v 0x1410 –p 0x9020 –u 4 This configuration provides a ECM interface as well as TTYs ('Enterprise Mode' according to the U620 Linux integration guide).

2015-11-17xhci: Add spurious wakeup quirk for LynxPoint-LP controllersLaura Abbott1-0/+1
commit fd7cd061adcf5f7503515ba52b6a724642a839c8 upstream. We received several reports of systems rebooting and powering on after an attempted shutdown. Testing showed that setting XHCI_SPURIOUS_WAKEUP quirk in addition to the XHCI_SPURIOUS_REBOOT quirk allowed the system to shutdown as expected for LynxPoint-LP xHCI controllers. Set the quirk back. Note that the quirk was originally introduced for LynxPoint and LynxPoint-LP just for this same reason. See: commit 638298dc66ea ("xhci: Fix spurious wakeups after S5 on Haswell") It was later limited to only concern HP machines as it caused regression on some machines, see both bug and commit: Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=66171 commit 6962d914f317 ("xhci: Limit the spurious wakeup fix only to HP machines") Later it was discovered that the powering on after shutdown was limited to LynxPoint-LP (Haswell-ULT) and that some non-LP HP machine suffered from spontaneous resume from S3 (which should not be related to the SPURIOUS_WAKEUP quirk at all). An attempt to fix this then removed the SPURIOUS_WAKEUP flag usage completely. commit b45abacde3d5 ("xhci: no switching back on non-ULT Haswell") Current understanding is that LynxPoint-LP (Haswell ULT) machines need the SPURIOUS_WAKEUP quirk, otherwise they will restart, and plain Lynxpoint (Haswell) machines may _not_ have the quirk set otherwise they again will restart.

2015-11-17xhci: Switch Intel Lynx Point LP ports to EHCI on shutdown.Denis Turischev1-0/+4
commits c09ec25d3684cad74d851c0f028a495999591279 and 0a939993bff117d3657108ca13b011fc0378aedb upstream. The same issue like with Panther Point chipsets. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS have work around for this, but not all. One example is Compulab's mini-desktop, the Intense-PC2. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. This patch should be backported to stable kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell" Signed-off-by: Denis Turischev <denis@compulab.co.il> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Patch "xhci: Switch Intel Lynx Point ports to EHCI on shutdown." commit c09ec25d3684cad74d851c0f028a495999591279 is not fully correct It switches both Lynx Point and Lynx Point-LP ports to EHCI on shutdown.

2015-11-17usb: Add device quirk for Logitech PTZ camerasVincent Palatin1-0/+7
commit 72194739f54607bbf8cfded159627a2015381557 upstream. Add a device quirk for the Logitech PTZ Pro Camera and its sibling the ConferenceCam CC3000e Camera. This fixes the failed camera enumeration on some boot, particularly on machines with fast CPU. Tested by connecting a Logitech PTZ Pro Camera to a machine with a Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles while recording the kernel logs and taking camera picture after each boot. Before the patch, more than 7% of the boots show some enumeration transfer failures and in a few of them, the kernel is giving up before actually enumerating the webcam. After the patch, the enumeration has been correct on every reboot.

2015-10-13xhci: fix off by one error in TRB DMA address boundary checkMathias Nyman1-1/+1
commit 7895086afde2a05fa24a0e410d8e6b75ca7c8fdd upstream. We need to check that a TRB is part of the current segment before calculating its DMA address. Previously a ring segment didn't use a full memory page, and every new ring segment got a new memory page, so the off by one error in checking the upper bound was never seen. Now that we use a full memory page, 256 TRBs (4096 bytes), the off by one didn't catch the case when a TRB was the first element of the next segment. This is triggered if the virtual memory pages for a ring segment are next to each in increasing order where the ring buffer wraps around and causes errors like: [ 106.398223] xhci_hcd 0000:00:14.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 0 comp_code 1 [ 106.398230] xhci_hcd 0000:00:14.0: Looking for event-dma fffd3000 trb-start fffd4fd0 trb-end fffd5000 seg-start fffd4000 seg-end fffd4ff0 The trb-end address is one outside the end-seg address.

commit 5fb2c782f451a4fb9c19c076e2c442839faf0f76 upstream. This device automatically switches itself to another mode (0x1405) unless the specific access pattern of Windows is followed in its initial mode. That makes a dirty unmount of the internal storage devices inevitable if they are mounted. So the card reader of such a device should be ignored, lest an unclean removal become inevitable.
