Descriptions

In the Linux kernel, the following vulnerability has been resolved:

usb: udc: remove warning when queue disabled ep

It is possible trigger below warning message from mass storage function,

WARNING: CPU: 6 PID: 3839 at drivers/usb/gadget/udc/core.c:294 usb_ep_queue+0x7c/0x104
pc : usb_ep_queue+0x7c/0x104
lr : fsg_main_thread+0x494/0x1b3c

Root cause is mass storage function try to queue request from main thread,
but other thread may already disable ep when function disable.

As there is no function failure in the driver, in order to avoid effort
to fix warning, change WARN_ON_ONCE() in usb_ep_queue() to pr_debug().

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: udc: elimina la advertencia cuando la cola está deshabilitada ep Es posible que se active el siguiente mensaje de advertencia desde la función de almacenamiento masivo, ADVERTENCIA: CPU: 6 PID: 3839 en drivers/usb/gadget/udc /core.c:294 usb_ep_queue+0x7c/0x104 pc: usb_ep_queue+0x7c/0x104 lr: fsg_main_thread+0x494/0x1b3c La causa principal es que la función de almacenamiento masivo intenta poner en cola la solicitud desde el hilo principal, pero es posible que otro hilo ya deshabilite ep cuando la función se deshabilita. Como no hay ningún fallo de función en el controlador, para evitar el esfuerzo de corregir la advertencia, cambie WARN_ON_ONCE() en usb_ep_queue() a pr_debug().
