Hi all, The following patchset enable the use of xfstests to test reflink functionality under ocfs2. The first patch tests the ability to reflink into and out of inline-data files on ocfs2. Patches 2-6 fix various problems with the tests that came up when qualifying ocfs2. The last patch maliciously corrupts ext4 and xfs filesystems to exploit nonexistent checking of i_size in order to coerce Linux into loading a file with negative size. It then exploits integer overflows in the VFS writeback code to hard lock the kernel. Don't run the tests in this patch ({shared,xfs}/40[01]) unless you have a fixed kernel (4.10) Comments and questions are, as always, welcome. --D -- To unsubscribe from this list: send the line "unsubscribe linux-xfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
