Summary
[none]
Details

In the Linux kernel, the following vulnerability has been resolved: aoe: avoid potential deadlock at setcapacity Move setcapacity() outside of the section procected by (&d->lock). To avoid possible interrupt unsafe locking scenario: CPU0 CPU1 ---- ---- [1] lock(&bdev->bdsizelock); localirqdisable(); [2] lock(&d->lock); [3] lock(&bdev->bdsizelock); <Interrupt> [4] lock(&d->lock); * DEADLOCK * Where 1 hold by zramadd()->setcapacity(). [2]lock(&d->lock) hold by aoeblkgdalloc(). And aoeblkgdalloc() is trying to acquire 3 at setcapacity() call. In this situation an attempt to acquire [4]lock(&d->lock) from aoecmdcfgrsp() will lead to deadlock. So the simplest solution is breaking lock dependency 2 -> 3 by moving setcapacity() outside.
