- usb: dwc3: core: remove lock of otg mode during gadget suspend/resume to avoid deadlock
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
usb: dwc3: core: remove lock of otg mode during gadget suspend/resume to avoid deadlock
When config CONFIGUSBDWC3DUALROLE is selected, and trigger system to enter suspend status with below command: echo mem > /sys/power/state There will be a deadlock issue occurring. Detailed invoking path as below: dwc3suspendcommon() spinlockirqsave(&dwc->lock, flags); <-- 1st dwc3gadgetsuspend(dwc); dwc3gadgetsoftdisconnect(dwc); spinlockirqsave(&dwc->lock, flags); <-- 2nd This issue is exposed by commit c7ebd8149ee5 ("usb: dwc3: gadget: Fix NULL pointer dereference in dwc3gadgetsuspend") that removes the code of checking whether dwc->gadgetdriver is NULL or not. It causes the following code is executed and deadlock occurs when trying to get the spinlock. In fact, the root cause is the commit 5265397f9442("usb: dwc3: Remove DWC3 locking during gadget suspend/resume") that forgot to remove the lock of otg mode. So, remove the redundant lock of otg mode during gadget suspend/resume.
