Niels Dossche 90ab34df66 usb: usbip: add missing device lock on tweak configuration cmd ... [ Upstream commit d088fabace ] The function documentation of usb_set_configuration says that its callers should hold the device lock. This lock is held for all callsites except tweak_set_configuration_cmd. The code path can be executed for example when attaching a remote USB device. The solution is to surround the call by the device lock. This bug was found using my experimental own-developed static analysis tool, which reported the missing lock on v5.17.2. I manually verified this bug report by doing code review as well. I runtime checked that the required lock is not held. I compiled and runtime tested this on x86_64 with a USB mouse. After applying this patch, my analyser no longer reports this potential bug.
