Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> xfs: fix finding a last resort AG in xfs_filestream_pick_ag<br /> <br /> When the main loop in xfs_filestream_pick_ag fails to find a suitable<br /> AG it tries to just pick the online AG. But the loop for that uses<br /> args-&gt;pag as loop iterator while the later code expects pag to be<br /> set. Fix this by reusing the max_pag case for this last resort, and<br /> also add a check for impossible case of no AG just to make sure that<br /> the uninitialized pag doesn&amp;#39;t even escape in theory.
