Subject: [PATCH 0/7] xfstests: misc reflink test fixes
Date: Wed, 04 Jan 2017 17:04:36 -0800 [thread overview]
Message-ID: <148357827617.7677.15595044775254927245.stgit@birch.djwong.org> (raw)
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.
