commit 31f42da31417bec88158f3cf62d19db836217f1e upstream.
Added exiting from the clock gating mode on USB Reset Detect interrupt if core in the clock gating mode. Added new condition to check core in clock gating mode or no.

usb: dwc2: fix possible NULL pointer dereference caused by driver concurrency

usb: dwc2: fix possible NULL pointer dereference caused by driver concurrency
[ Upstream commit ef307bc6ef04e8c1ea843231db58e3afaafa9fa6 ]
In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue():
spin_lock_irqsave(&hsotg->lock, flags); ... if (!urb->hcpriv) { dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n"); goto out; } rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv ... out: spin_unlock_irqrestore(&hsotg->lock, flags);
When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are concurrently executed, the NULL check of "urb->hcpriv" can be executed before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL pointer dereference.
This possible bug is found by an experimental static analysis tool developed by myself. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. The above possible bug is reported, when my tool analyzes the source code of Linux 6.5.
To fix this possible bug, "urb->hcpriv = NULL" should be executed with holding the lock "hsotg->lock". After using this patch, my tool never reports the possible bug, with the kernelconfiguration allyesconfig for x86_64. Because I have no associated hardware, I cannot test the patch in runtime testing, and just verify it according to the code logic.

usb: dwc2: add otg_rev and otg_caps information for gadget driver
Currently the dwc2 doesn't fill in the 'otg_caps' of usb_gadget structure. When registering a gadget device (e.g. via configfs), the usb_otg_descriptor_init() checks the 'otg_caps' and 'otg_rev'. It defaults to HNP and SRP bmAttributes if unspecified. There may be a mismatch with what's being set in dwc2 params structure. This result in the descriptors to be miss-configured in this case.
So replace 'otg_cap' bit field by 'otg_caps' structure, so hnp, srp and otg_rev' can be configured directly in the params. It's then provided to the gadget struct. These parameters can be tuned for each platform. In case it's not set, it will default to current behavior.
Also add option to setup these from the device tree by calling of_usb_update_otg_caps(). This provides support for standard properties such as "otg-rev", "hnp-disable" and "srp-disable" (see usb-drd.yaml).

usb: dwc2: Skip clock gating on Samsung SoCs
Commit 0112b7ce68ea ("usb: dwc2: Update dwc2_handle_usb_suspend_intr function.") changed the way the driver handles power down modes in a such way that it uses clock gating when no other power down mode is available.
This however doesn't work well on the DWC2 implementation used on the Samsung SoCs. When a clock gating is enabled, system hangs. It looks that the proper clock gating requires some additional glue code in the shared USB2 PHY and/or Samsung glue code for the DWC2. To restore driver operation on the Samsung SoCs simply skip enabling clock gating mode until one finds what is really needed to make it working reliably.
