Details

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

md: Fix missing release of 'active_io' for flush

submitflushes atomicset(&mddev->flushpending, 1); rdevforeachrcu(rdev, mddev) atomicinc(&mddev->flushpending); bi->biendio = mdendflush submitbio(bi); /* flush io is done first */ mdendflush if (atomicdecandtest(&mddev->flushpending)) percpurefput(&mddev->activeio) -> active_io is not released

if (atomicdecandtest(&mddev->flushpending)) -> missing release of active_io

For consequence, mddevsuspend() will wait for 'activeio' to be zero forever.

Fix this problem by releasing 'activeio' in submitflushes() if 'flush_pending' is decreased to zero.
