Subject: [PATCH] apparmor: signedness bug in aa_xattrs_match()
Message-ID: <20180319103444.GC8543@mwanda>
To: linux-security-module@vger.kernel.org
List-Id: linux-security-module.vger.kernel.org

The "size" variable needs to be signed ssize_t so that the error
handling works correctly.

Fixes: 8e51f9087f40 ("apparmor: Add support for attaching profiles via xattr, presence and value")
Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com>
