Details

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

net: cadence: macb: Fix a possible deadlock in macbhalttx.

There is a situation where after THALT is set high, TGO stays high as well. Because jiffies are never updated, as we are in a context with interrupts disabled, we never exit that loop and have a deadlock.

That deadlock was noticed on a sama5d4 device that stayed locked for days.

Use retries instead of jiffies so that the timeout really works and we do not have a deadlock anymore.
