Subject: Apply "vfs: don't do RCU lookup of empty pathnames" to stable
Date: Thu, 15 Feb 2018 11:11:37 -0800 [thread overview]
Message-ID: <20180215191137.GA197331@gmail.com> (raw)
Hi Greg, here's another one. When you have a chance can you please apply commit
c0eb027e5aef ("vfs: don't do RCU lookup of empty pathnames") to the stable
trees? I can reproduce the use-after-free on 4.4-stable and 4.9-stable, and it
is fixed by the patch. And I wasn't able to check 3.18 because KASAN isn't
available there, but I think the bug there as well. Thanks,
Eric
