Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net: cadence: macb: Fix a possible deadlock in macb_halt_tx.<br /> <br /> There is a situation where after THALT is set high, TGO stays high as<br /> well. Because jiffies are never updated, as we are in a context with<br /> interrupts disabled, we never exit that loop and have a deadlock.<br /> <br /> That deadlock was noticed on a sama5d4 device that stayed locked for days.<br /> <br /> Use retries instead of jiffies so that the timeout really works and we do<br /> not have a deadlock anymore.
