2023-11-22USB: dwc3: qcom: fix resource leaks on probe deferralJohan Hovold1-3/+6
The driver needs to deregister and free the newly allocated dwc3 core platform device on ACPI probe errors (e.g. probe deferral) and on driver unbind but instead it leaked those resources while erroneously dropping a reference to the parent platform device which is still in use. For OF probing the driver takes a reference to the dwc3 core platform device which has also always been leaked. Fix the broken ACPI tear down and make sure to drop the dwc3 core reference for both OF and ACPI.

2023-11-21USB: xhci-plat: fix legacy PHY double initJohan Hovold1-20/+30
Commits 7b8ef22ea547 ("usb: xhci: plat: Add USB phy support") and 9134c1fd0503 ("usb: xhci: plat: Add USB 3.0 phy support") added support for looking up legacy PHYs from the sysdev devicetree node and initialising them. This broke drivers such as dwc3 which manages PHYs themself as the PHYs would now be initialised twice, something which specifically can lead to resources being left enabled during suspend (e.g. with the usb_phy_generic PHY driver). As the dwc3 driver uses driver-name matching for the xhci platform device, fix this by only looking up and initialising PHYs for devices that have been matched using OF. Note that checking that the platform device has a devicetree node would currently be sufficient, but that could lead to subtle breakages in case anyone ever tries to reuse an ancestor's node.

2023-11-21usb: config: fix iteration issue in 'usb_get_bos_descriptor()'Niklas Neronin1-1/+2
The BOS descriptor defines a root descriptor and is the base descriptor for accessing a family of related descriptors. Function 'usb_get_bos_descriptor()' encounters an iteration issue when skipping the 'USB_DT_DEVICE_CAPABILITY' descriptor type. This results in the same descriptor being read repeatedly. To address this issue, a 'goto' statement is introduced to ensure that the pointer and the amount read is updated correctly. This ensures that the function iterates to the next descriptor instead of reading the same descriptor repeatedly.

2023-11-21usb: cdnsp: Fix deadlock issue during using NCM gadgetPawel Laszczak1-0/+3
The interrupt service routine registered for the gadget is a primary handler which mask the interrupt source and a threaded handler which handles the source of the interrupt. Since the threaded handler is voluntary threaded, the IRQ-core does not disable bottom halves before invoke the handler like it does for the forced-threaded handler. Due to changes in networking it became visible that a network gadget's completions handler may schedule a softirq which remains unprocessed. The gadget's completion handler is usually invoked either in hard-IRQ or soft-IRQ context. In this context it is enough to just raise the softirq because the softirq itself will be handled once that context is left. In the case of the voluntary threaded handler, there is nothing that will process pending softirqs. Which means it remain queued until another random interrupt (on this CPU) fires and handles it on its exit path or another thread locks and unlocks a lock with the bh suffix. Worst case is that the CPU goes idle and the NOHZ complains about unhandled softirqs. Disable bottom halves before acquiring the lock (and disabling interrupts) and enable them after dropping the lock. This ensures that any pending softirqs will handled right away. cc: stable@vger.kernel.org Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver") Signed-off-by: Pawel Laszczak <pawell@cadence.com> Acked-by: Peter Chen <peter.chen@kernel.org> Link: https://lore.kernel.org/r/20231108093125.224963-1-pawell@cadence.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-11-06Revert "usb: phy: add usb phy notify port status API"Johan Hovold1-23/+0
This reverts commit a08799cf17c22375752abfad3b4a2b34b3acb287. The recently added Realtek PHY drivers depend on the new port status notification mechanism which was built on the deprecated USB PHY implementation and devicetree binding. Specifically, using these PHYs would require describing the very same PHY using both the generic "phy" property and the deprecated "usb-phy" property which is clearly wrong. We should not be building new functionality on top of the legacy USB PHY implementation even if it is currently stuck in some kind of transitional limbo. Revert the new notification interface which is broken by design.

Update USB_RAW_IOCTL_EVENT_FETCH to also report suspend, resume, reset, and disconnect events. This allows the code that emulates a USB device via Raw Gadget to handle these events. For example, the device can restart enumeration when it gets reset. Also do not print a WARNING when the event queue overflows. With these new events being queued, the queue might overflow if the device emulation code stops fetching events. Also print debug messages when a non-control event is received.

2023-10-27usb: raw-gadget: don't disable device if usb_ep_queue failsAndrey Konovalov1-2/+0
During device operation, the host might decide to reset a device emulated via Raw Gadget. In this case, if the device emulation code has endpoint requests queued, usb_ep_queue will fail with -ESHUTDOWN. Currently, this disables the Raw Gadget device and makes the emulation code unable to proceed. Do not disable the Raw Gadget device if usb_ep_queue fails.

2023-10-27usb: raw-gadget: properly handle interrupted requestsAndrey Konovalov1-10/+16
Currently, if a USB request that was queued by Raw Gadget is interrupted (via a signal), wait_for_completion_interruptible returns -ERESTARTSYS. Raw Gadget then attempts to propagate this value to userspace as a return value from its ioctls. However, when -ERESTARTSYS is returned by a syscall handler, the kernel internally restarts the syscall. This doesn't allow userspace applications to interrupt requests queued by Raw Gadget (which is required when the emulated device is asked to switch altsettings). It also violates the implied interface of Raw Gadget that a single ioctl must only queue a single USB request. Instead, make Raw Gadget do what GadgetFS does: check whether the request was interrupted (dequeued with status == -ECONNRESET) and report -EINTR to userspace.

2023-10-27usb: gadget: aspeed_udc: Convert to platform remove callback returning voidUwe Kleine-König1-6/+13
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). ast_udc_remove() is one of these functions that return an error code after doing only a partial cleanup. Replace the core's error message by a more drastic one and still convert the driver to .remove_new(). Note the only semantic change here is the changed error message.

2023-10-27usb: typec: fsa4480: Add support to swap SBU orientationLuca Weiss1-0/+71
On some hardware designs the AUX+/- lanes are connected reversed to SBU1/2 compared to the expected design by FSA4480. Made more complicated, the otherwise compatible Orient-Chip OCP96011 expects the lanes to be connected reversed compared to FSA4480. * FSA4480 block diagram shows AUX+ connected to SBU2 and AUX- to SBU1. * OCP96011 block diagram shows AUX+ connected to SBU1 and AUX- to SBU2. So if OCP96011 is used as drop-in for FSA4480 then the orientation handling in the driver needs to be reversed to match the expectation of the OCP96011 hardware. Support parsing the data-lanes parameter in the endpoint node to swap this in the driver. The parse_data_lanes_mapping function is mostly taken from nb7vpq904m.c.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. The function mtu3_remove() can only return a non-zero value if ssusb->dr_mode is neiter USB_DR_MODE_PERIPHERAL nor USB_DR_MODE_HOST nor USB_DR_MODE_OTG. In this case however the probe callback doesn't succeed and so the remove callback isn't called at all. So the code branch resulting in this error path could just be dropped were it not for the compiler choking on "enumeration value 'USB_DR_MODE_UNKNOWN' not handled in switch [-Werror=switch]". So instead replace this code path by a WARN_ON and then mtu3_remove() be converted to return void trivially.
