Title
wifi: libertas: don't kill URBs in interrupt context
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: libertas: don't kill URBs in interrupt context
Serialization for the TX path was enforced by calling
usb_kill_urb()/usb_kill_anchored_urbs(), to prevent transmission before
a previous URB was completed. usb_tx_block() can be called from
interrupt context (e.g. in the HCD giveback path), so we can't always
use it to kill in-flight URBs.
Prevent sleeping during interrupt context by checking the tx_submitted
anchor for existing URBs. We now return -EBUSY, to indicate there's
a pending request.
