commit 07e72b95 upstream. Some touchscreens have buggy firmware which claims remote wakeup to be enabled after a reset. They nevertheless crash if the feature is cleared by the host. Add a check for reset resume before checking for an enabled remote wakeup feature. On compliant devices the feature must be cleared after a reset anyway. Signed-off-by:

commit 87ed5003 upstream. If the rpc_task exits while holding the socket write lock before it has allocated an rpc slot, then the usual mechanism for releasing the write lock in xprt_release() is defeated. The problem occurs if the call to xprt_lock_write() initially fails, so that the rpc_task is put on the xprt->sending wait queue. If the task exits after being assigned the lock by __xprt_lock_write_func, but before it has retried the call to xprt_lock_and_alloc_slot(), then it calls xprt_release() while holding the write lock, but will immediately exit due to the test for task->tk_rqstp != NULL.

commit 3b4bc7bc upstream. This patch fixes some code that implements a work-around to a hardware bug in the ac97 controller on the pxa27x. A bug in the controller's warm reset functionality requires that the mfp used by the controller as the AC97_nRESET line be temporarily reconfigured as a generic output gpio (AF0) and manually held high for the duration of the warm reset cycle. This is what was done in the original code, but it was broken long ago by commit fb1bf8cd ([ARM] pxa: introduce processor specific pxa27x_assert_ac97reset()) which changed the mfp to a GPIO input instead of a high output. The fix requires the ac97 controller to obtain the gpio via gpio_request_one(), with arguments that configure the gpio as an output initially driven high. Tested on a palm treo 680 machine. Reportedly, this broken code only prevents a warm reset on hardware that lacks a pull-up on the line, which appears to be the case for me. Signed-off-by:

commit 41b645c8 upstream. Cold reset on the pxa27x currently fails and pxa2xx_ac97_try_cold_reset: cold reset timeout (GSR=0x44) appears in the kernel log. Through trial-and-error (the pxa270 developer's manual is mostly incoherent on the topic of ac97 reset), I got cold reset to complete by setting the WARM_RST bit in the GCR register (and later noticed that pxa3xx does this for cold reset as well). Also, a timeout loop is needed to wait for the reset to complete. Tested on a palm treo 680 machine. Signed-off-by:

commit bc3b7756 upstream. Current code does integer division (min_vol = min_uV / 1000) before pass min_vol to max8997_get_voltage_proper_val(). So it is possible min_vol is truncated to a smaller value. For example, if the request min_uV is 800900 for ldo. min_vol = 800900 / 1000 = 800 (mV) Then max8997_get_voltage_proper_val returns 800 mV for this case which is lower than the requested voltage. Use uV rather than mV in voltage_map_desc to prevent truncation by integer division. Signed-off-by:

commit c0729eee upstream. Éric Piel reported a kernel oops in the "comedi_test" module. It was a NULL pointer dereference within `waveform_ai_interrupt()` (actually a timer function) that sometimes occurred when a running asynchronous command is cancelled (either by the `COMEDI_CANCEL` ioctl or by closing the device file). This seems to be a race between the caller of `waveform_ai_cancel()` which on return from that function goes and tears down the running command, and the timer function which uses the command. In particular, `async->cmd.chanlist` gets freed (and the pointer set to NULL) by `do_become_nonbusy()` in "comedi_fops.c" but a previously scheduled `waveform_ai_interrupt()` timer function will dereference that pointer regardless, leading to the oops. Fix it by replacing the `del_timer()` call in `waveform_ai_cancel()` with `del_timer_sync()`. Signed-off-by:

commit 34b55d8c upstream. The minimum period was set to 357 ns, while the divider for these boards is 50 ns. This prevented to output at maximum speed as ni_ao_cmdtest() would return 357 but would not accept it. Not sure why it was set to 357 ns (this was done before the git history, which starts 5 years ago). My guess is that it comes from reading the specification stating a 2.8 MHz rate (~ 357 ns). The latest specification states a 2.86 MHz rate (~ 350 ns), which makes a lot more sense. Tested on a pci-6251. Signed-off-by:

This patch fixes below issues in the code to handle assoc failure case correctly. 1) "status" variable in mwifiex_wait_queue_complete() is not correctly updated.

commit c52804a4 upstream. The USB core hub thread (khubd) is designed with external USB hubs in mind. It expects that if a port status change bit is set, the hub will continue to send a notification through the hub status data transfer. Basically, it expects hub notifications to be level-triggered. The xHCI host controller is designed to be edge-triggered on the logical 'OR' of all the port status change bits. When all port status change bits are clear, and a new change bit is set, the xHC will generate a Port Status Change Event. If another change bit is set in the same port status register before the first bit is cleared, it will not send another event. This means that the hub code may lose port status changes because of race conditions between clearing change bits. The user sees this as a "dead port" that doesn't react to device connects. The fix is to turn on port polling whenever a new change bit is set. Once the USB core issues a hub status request that shows that no change bits are set in any USB ports, turn off port polling. We can't allow the USB core to poll the roothub for port events during host suspend because if the PCI host is in D3cold, the port registers will be all f's. Instead, stop the port polling timer, and unconditionally restart it when the host resumes. If there are no port change bits set after the resume, the first call to hub_status_data will disable polling. This patch should be backported to stable kernels with the first xHCI support, 2.6.31 and newer, that include the commit 0f2a7930 "USB: xhci: Root hub support." There will be merge conflicts because the check for HC_STATE_SUSPENDED was moved into xhci_suspend in 3.8. Signed-off-by:

commit 65bdac5e upstream. An empty port can transition to either Inactive or Compliance Mode if a newly connected USB 3.0 device fails to link train. In that case, we issue a warm reset. Some devices, such as John's Roseweil eusb3 enclosure, slip back into Compliance Mode after the warm reset. The current warm reset code does not check for device connect status on warm reset completion, and it incorrectly reports the warm reset succeeded. This causes the USB core to attempt to send a Set Address control transfer to a port in Compliance Mode, which will always fail. Make hub_port_wait_reset check the current connect status and link state after the warm reset completes. Return a failure status if the device is disconnected or the link state is Compliance Mode or SS.Inactive. Make hub_events disable the port if warm reset fails. This will disable the port, and then bring it back into the RxDetect state. Make the USB core ignore the connect change until the device reconnects. Note that this patch does NOT handle connected devices slipping into the Inactive state very well. This is a concern, because devices can go into the Inactive state on U1/U2 exit failure. However, the fix for that case is too large for stable, so it will be submitted in a separate patch. This patch should be backported to kernels as old as 3.2, contain the commit ID 75d7cf72 "usbcore: refine warm reset logic" Signed-off-by:

commit 4f43447e upstream. The port reset code bails out early if the current connect status is cleared (device disconnected). If we're issuing a hot reset, it may also look at the link state before the reset is finished. Section 10.14.2.6 of the USB 3.0 spec says that when a port enters the Error state or Resetting state, the port connection bit retains the value from the previous state. Therefore we can't trust it until the reset finishes. Also, the xHCI spec section 4.19.1.2.5 says software shall ignore the link state while the port is resetting, as it can be in an unknown state. The port state during reset is also unknown for USB 2.0 hubs. The hub sends a reset signal by driving the bus into an SE0 state. This overwhelms the "connect" signal from the device, so the port can't tell whether anything is connected or not. Fix the port reset code to ignore the port link state and current connect bit until the reset finishes, and USB_PORT_STAT_RESET is cleared. Remove the check for USB_PORT_STAT_C_BH_RESET in the warm reset case, because it's redundant. When the warm reset finishes, the port reset bit will be cleared at the same time USB_PORT_STAT_C_BH_RESET is set. Remove the now-redundant check for a cleared USB_PORT_STAT_RESET bit in the code to deal with the finished reset. This patch should be backported to all stable kernels. Signed-off-by:

commit 41e7e056 upstream. If hot and warm reset fails, or a port remains in the Compliance Mode, the USB core needs to be able to disable a USB 3.0 port. Unlike USB 2.0 ports, once the port is placed into the Disabled link state, it will not report any new device connects. To get device connect notifications, we need to put the link into the Disabled state, and then the RxDetect state. The xHCI driver needs to atomically clear all change bits on USB 3.0 port disable, so that we get Port Status Change Events for future port changes. We could technically do this in the USB core instead of in the xHCI roothub code, since the port state machine can't advance out of the disabled state until we set the link state to RxDetect. However, external USB 3.0 hubs don't need this code. They are level-triggered, not edge-triggered like xHCI, so they will continue to send interrupt events when any change bit is set. Therefore it doesn't make sense to put this code in the USB core. This patch is part of a series to fix several reports of infinite loops on device enumeration failure. This includes John, when he boots with a USB 3.0 device (Roseweil eusb3 enclosure) attached to his NEC 0.96 host controller. The fix requires warm reset support, so it does not make sense to backport this patch to stable kernels without warm reset support.

commit 8b8132bc upstream. When the USB core finishes reseting a USB device, the xHCI driver sends a Reset Device command to the host. The xHC then updates its internal representation of the USB device to the 'Default' device state. If the device was already in the Default state, the xHC will complete the command with an error status. If a device needs to be reset several times during enumeration, the second reset will always fail because of the xHCI Reset Device command. This can cause issues during enumeration. For example, usb_reset_and_verify_device calls into hub_port_init in a loop. Say that on the first call into hub_port_init, the device is successfully reset, but doesn't respond to several set address control transfers. Then the port will be disabled, but the udev will remain in tact. usb_reset_and_verify_device will call into hub_port_init again. On the second call into hub_port_init, the device will be reset, and the xHCI driver will issue a Reset Device command. This command will fail (because the device is already in the Default state), and usb_reset_and_verify_device will fail. The port will be disabled, and the device won't be able to enumerate. Fix this by ignoring the return value of the HCD reset_device callback. This commit should be backported to kernels as old as 3.2, that contain the commit 75d7cf72 "usbcore: refine warm reset logic".

commit 1c7439c6 upstream. USB 3.0 hubs and roothubs will automatically transition a failed hot reset to a warm (BH) reset. In that case, the warm reset change bit will be set, and the link state change bit may also be set. Change hub_port_finish_reset to unconditionally clear those change bits for USB 3.0 hubs. If these bits are not cleared, we may lose port change events from the roothub.

commit 55c1945e upstream. A high speed control or bulk endpoint may have bInterval set to zero, which means it does not NAK. If bInterval is non-zero, it means the endpoint NAKs at a rate of 2^(bInterval - 1). The xHCI code to compute the NAK interval does not handle the special case of zero properly. The current code unconditionally subtracts one from bInterval and uses it as an exponent. This causes a very large bInterval to be used, and warning messages like these will be printed: usb 1-1: ep 0x1 - rounding interval to 32768 microframes, ep desc says 0 microframes This may cause the xHCI host hardware to reject the Configure Endpoint command, which means the HS device will be unusable under xHCI ports. This patch should be backported to kernels as old as 2.6.31, that contain commit dfa49c4a "USB: xhci - fix math in xhci_get_endpoint_interval()". Reported-by:

commit f4953fe6 upstream. When a file system is mounted on a virtio-blk disk, we then remove it and then reattach it, the reattached disk gets the same disk name and ids as the hot removed one. This leads to very nasty effects - mostly rendering the newly attached device completely unusable. Trying what happens when I do the same thing with a USB device, I saw that the sd node simply doesn't get free'd when a device gets forcefully removed. Imitate the same behavior for vd devices. This way broken vd devices simply are never free'd and newly attached ones keep working just fine. Signed-off-by:

commit 1d16638e 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. Signed-off-by:
