dwc->desired_dr_role is changed by dwc3_set_mode inside a spinlock but then read by __dwc3_set_mode outside of that lock. This can lead to a race condition when very quick successive role switch events happen: CPU A dwc3_set_mode(DWC3_GCTL_PRTCAP_HOST) // first role switch event spin_lock_irqsave(&dwc->lock, flags); dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_HOST spin_unlock_irqrestore(&dwc->lock, flags); queue_work(system_freezable_wq, &dwc->drd_work); CPU B __dwc3_set_mode // .... spin_lock_irqsave(&dwc->lock, flags); // desired_dr_role is DWC3_GCTL_PRTCAP_HOST dwc3_set_prtcap(dwc, dwc->desired_dr_role); spin_unlock_irqrestore(&dwc->lock, flags); CPU A dwc3_set_mode(DWC3_GCTL_PRTCAP_DEVICE) // second event spin_lock_irqsave(&dwc->lock, flags); dwc->desired_dr_role = mode; // DWC3_GCTL_PRTCAP_DEVICE spin_unlock_irqrestore(&dwc->lock, flags); CPU B (continues running __dwc3_set_mode) switch (dwc->desired_dr_role) { // DWC3_GCTL_PRTCAP_DEVICE // .... case DWC3_GCTL_PRTCAP_DEVICE: // .... ret = dwc3_gadget_init(dwc); We then have DWC3_GCTL.DWC3_GCTL_PRTCAPDIR = DWC3_GCTL_PRTCAP_HOST and dwc->current_dr_role = DWC3_GCTL_PRTCAP_HOST but initialized the controller in device mode. It's also possible to get into a state where both host and device are intialized at the same time. Fix this race by creating a local copy of desired_dr_role inside __dwc3_set_mode while holding dwc->lock.

Unify error handling at the end of the function, reducing the risk of missing something on one of the error paths. Moving the increment of opts->refcnt later means there is no need to decrement it on the error path and is safe as this is guarded by opts->lock which is held for this entire section.

The embedded struct cdev does not have its lifetime correctly tied to the enclosing struct f_hidg, so there is a use-after-free if /dev/hidgN is held open while the gadget is deleted. This can readily be replicated with libusbgx's example programs (for conciseness - operating directly via configfs is equivalent): gadget-hid exec 3<> /dev/hidg0 gadget-vid-pid-remove exec 3<&- Pull the existing device up in to struct f_hidg and make use of the cdev_device_{add,del}() helpers. This changes the lifetime of the device object to match struct f_hidg, but note that it is still added and deleted at the same time.

Jean Delvare authored
Since commit 0166dc11 ("of: make CONFIG_OF user selectable"), it is possible to test-build any driver which depends on OF on any architecture by explicitly selecting OF. Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

Some port drivers may want to set a Type-C partner as a parent for a USB Power Delivery object, but the Type-C partner struct isn't exposed outside of the Type-C class driver. Add a wrapper to usb_power_delivery_register() which sets the provided Type-C partner as a parent to the USB PD object. This helps to avoid exposing the Type-C partner's device struct unnecessarily.

Vincent Mailhol authored
USB drivers do not need to call usb_set_intfdata(intf, NULL) in their usb_driver::disconnect callback because the core already does it in [1]. However, this fact is widely unknown, c.f.: $ git grep "usb_set_intfdata(.*NULL)" | wc -l 215 Especially, setting the interface to NULL before all action completed can result in a NULL pointer dereference. Not calling usb_set_intfdata() at all in disconnect() is the safest method. Add documentation to usb_set_intfdata() to clarify this point. Also remove the call in usb-skeletion's disconnect() not to confuse the new comers.

It can take more than one second to check each connector when the system is resumed. So if you have, say, eight connectors, it may take eight seconds for ucsi_resume() to finish. That's a bit too much. This will modify ucsi_resume() so that it schedules a work where the interface is actually resumed instead of checking the connectors directly. The connections will also be checked in separate tasks which are queued for each connector separately.
