2013-08-02usb: Clear both buffers when clearing a control transfer TT buffer.William Gulland
commit 2c7b871b9102c497ba8f972aa5d38532f05b654d upstream. Control transfers have both IN and OUT (or SETUP) packets, so when clearing TT buffers for a control transfer it's necessary to send two HUB_CLEAR_TT_BUFFER requests to the hub.

2013-08-02xhci: fix null pointer dereference on ring_doorbell_for_active_ringsOleksij Rempel
commit d66eaf9f89502971fddcb0de550b01fa6f409d83 upstream. 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. This patch should be backported to kernels as old as 2.6.35, that contain the commit e9df17eb1408cfafa3d1844bfc7f22c7237b31b8 "USB: xhci: Correct assumptions about number of rings per endpoint" Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
2013-08-02usb: host: xhci: Enable XHCI_SPURIOUS_SUCCESS for all controllers with xhci 1.0George Cherian
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.

2013-08-02xhci: Avoid NULL pointer deref when host dies.Sarah Sharp
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."

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".

Changes are: - add VendorID ProductID to device tables - skip unstable speed check because FRWD uses 115200bps - skip reset at probe which is an issue workaround for this particular device.

2013-06-19USB: revert periodic scheduling bugfixAlan Stern
commit fdc03438f53a00294ed9939eb3a1f6db6f3d8963 upstream. This patch reverts commit 3e619d04159be54b3daa0b7036b0ce9e067f4b5d (USB: EHCI: fix bug in scheduling periodic split transfers). The commit was valid -- it fixed a real bug -- but the periodic scheduler in ehci-hcd is in such bad shape (especially the part that handles split transactions) that fixing one bug is very likely to cause another to surface. That's what happened in this case; the result was choppy and noisy playback on certain 24-bit audio devices. The only real fix will be to rewrite this entire section of code. My next project...

commit 5bf8fae33d14cc5c3c53a926f9079f92c8b082b0 upstream. we never allocate a TRB pool for physical endpoints 0 and 1 so trying to free it (a invalid TRB pool pointer) will lead us in a warning while removing dwc3.ko module.

2013-06-19xhci - correct comp_mode_recovery_timer on return from hibernateTony Camuso
commit 77df9e0b799b03e1d5d9c68062709af5f637e834 upstream. Commit 71c731a2 (usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware) was a workaround for systems using the SN65LVPE502CP, controller, but it introduced a bug in resume from hibernate. The fix created a timer, comp_mode_recovery_timer, which is deleted from a timer list when xhci_suspend() is called. However, the hibernate image, including the timer list containing the comp_mode_recovery_timer, had already been saved before the timer was deleted. Upon resume from hibernate, the list containing the comp_mode_recovery_timer is restored from the image saved to disk, and xhci_resume(), assuming that the timer had been deleted by xhci_suspend(), makes a call to compliance_mode_recoery_timer_init(), which creates a new instance of the comp_mode_recovery_timer and attempts to place it into the same list in which it is already active, thus corrupting the list during the list_add() call. At this point, a call trace is emitted indicating the list corruption. Soon afterward, the system locks up, the watchdog times out, and the ensuing NMI crashes the system. The problem did not occur when resuming from suspend. In suspend, the image in RAM remains exactly as it was when xhci_suspend() deleted the comp_mode_recovery_timer, so there is no problem when xhci_resume() creates a new instance of this timer and places it in the still empty list. This patch avoids the problem by deleting the timer in xhci_resume() when resuming from hibernate. Now xhci_resume() can safely make the call to create a new instance of this timer, whether returning from suspend or hibernate. Thanks to Alan Stern for his help with understanding the problem. [Sarah reworked this patch to cover the case where the xHCI restore register operation fails, and (temp & STS_SRE) is true (and we re-init the host, including re-init for the compliance mode), but hibernate is false. The original patch would have caused list corruption in this case.] This patch should be backported to kernels as old as 3.2, that contain the commit 71c731a296f1b08a3724bd1b514b64f1bda87a23 "usb: host: xhci: Fix Compliance Mode on SN65LVPE502CP Hardware" Signed-off-by: Tony Camuso <tcamuso@redhat.com> Tested-by: Tony Camuso <tcamuso@redhat.com> Acked-by: Don Zickus <dzickus@redhat.com> Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>

2013-06-19xhci-mem: init list heads at the beginning of initSergio Aguirre
commit 331de00a64e5027365145bdf51da27b9ce15dfd5 upstream. It is possible that we fail on xhci_mem_init, just before doing the INIT_LIST_HEAD, and calling xhci_mem_cleanup. Problem is that, the list_for_each_entry_safe macro, assumes list heads are initialized (not NULL), and dereferences their 'next' pointer, causing a kernel panic if this is not yet initialized. Let's protect from that by moving inits to the beginning. This patch should be backported to kernels as old as 3.2, that contain the commit 9574323c39d1f8359a04843075d89c9f32d8b7e6 "xHCI: test USB2 software LPM".

commit a83d6755814e4614ba77e15d82796af0f695c6b8 upstream. When a device attached to the roothub is suspended, the endpoint rings are stopped. The host may generate a completion event with the completion code set to 'Stopped' or 'Stopped Invalid' when the ring is halted. The current xHCI code prints a warning in that case, which can be really annoying if the USB device is coming into and out of suspend. Remove the unnecessary warning.
