xfs: xfs_ioctl: fix information leak to userland al_hreq is copied from userland. If al_hreq.buflen is not properly aligned then xfs_attr_list will ignore the last bytes of kbuf. These bytes are unitialized. It leads to leaking of contents of kernel stack memory. Signed-off-by: Vasiliy Kulikov <segooon@gmail.com> Signed-off-by: Alex Elder <aelder@sgi.com>
