In the Linux kernel, the following vulnerability has been resolved:
xfs: don't wrap around quota ids in dqiterate
LOLLM noticed that q id is an unsigned 32-bit variable. If it happens
to be set to XFS DQ ID MAX due to a filesystem that actually has a dquot
for ID MAX, then this addition will truncate to zero and the iteration
starts over. Fix this by casting to u64.
