#1392951 — [PATCH 4.4 023/163] dmaengine: pxa_dma: fix the maximum requestor line

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Robert Jarzmik <robert.jarzmik@free.fr>

commit 6bab1c6afdca0371cfa957079b36b78d12dd2cf5 upstream.

The current number of requestor lines is limited to 31. This was an
error of a previous commit, as this number is platform dependent, and is
actually :
 - for pxa25x: 40 requestor lines
 - for pxa27x: 75 requestor lines
 - for pxa3xx: 100 requestor lines

The previous testing did not reveal the faulty constant as on pxa[23]xx
platforms, only camera, MSL and USB are above requestor 32, and in these
only the camera has a driver using dma.

#1392957 — [PATCH 4.4 016/163] usb: gadget: f_fs: Fix use-after-free

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lars-Peter Clausen <lars@metafoo.de>

commit 38740a5b87d53ceb89eb2c970150f6e94e00373a upstream.

When using asynchronous read or write operations on the USB endpoints the
issuer of the IO request is notified by calling the ki_complete() callback
of the submitted kiocb when the URB has been completed.

Calling this ki_complete() callback will free kiocb. Make sure that the
structure is no longer accessed beyond that point, otherwise undefined
behaviour might occur.

#1392964 — [PATCH 4.4 020/163] debugfs: Make automount point inodes permanently empty

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Seth Forshee <seth.forshee@canonical.com>

commit 87243deb88671f70def4c52dfa7ca7830707bd31 upstream.

Starting with 4.1 the tracing subsystem has its own filesystem
which is automounted in the tracing subdirectory of debugfs.
Prior to this debugfs could be bind mounted in a cloned mount
namespace, but if tracefs has been mounted under debugfs this
now fails because there is a locked child mount. This creates
a regression for container software which bind mounts debugfs
to satisfy the assumption of some userspace software.

In other pseudo filesystems such as proc and sysfs we're already
creating mountpoints like this in such a way that no dirents can
be created in the directories, allowing them to be exceptions to
some MNT_LOCKED tests. In fact we're already do this for the
tracefs mountpoint in sysfs.

Do the same in debugfs_create_automount(), since the intention
here is clearly to create a mountpoint. This fixes the regression,
as locked child mounts on permanently empty directories do not
cause a bind mount to fail.

#1392967 — [PATCH 4.4 002/163] block: loop: fix filesystem corruption in case of aio/dio

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ming Lei <ming.lei@canonical.com>

commit a7297a6a3a3322b054592e8e988981d2f5f29cc4 upstream.

Starting from commit e36f620428(block: split bios to max possible length),
block core starts to split bio in the middle of bvec.

Unfortunately loop dio/aio doesn't consider this situation, and
always treat 'iter.iov_offset' as zero. Then filesystem corruption
is observed.

This patch figures out the offset of the base bvevc via
'bio->bi_iter.bi_bvec_done' and fixes the issue by passing the offset
to iov iterator.

#1392971 — [PATCH 4.4 021/163] dmaengine: dw: fix master selection

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

commit 3fe6409c23e2bee4b2b1b6d671d2da8daa15271c upstream.

The commit 895005202987 ("dmaengine: dw: apply both HS interfaces and remove
slave_id usage") cleaned up the code to avoid usage of depricated slave_id
member of generic slave configuration.

Meanwhile it broke the master selection by removing important call to
dwc_set_masters() in ->device_alloc_chan_resources() which copied masters from
custom slave configuration to the internal channel structure.

Everything works until now since there is no customized connection of
DesignWare DMA IP to the bus, i.e. one bus and one or more masters are in use.
The configurations where 2 masters are connected to the different masters are
not working anymore. We are expecting one user of such configuration and need
to select masters properly. Besides that it is obviously a performance
regression since only one master is in use in multi-master configuration.

Select masters in accordance with what user asked for. Keep this patch in a form
more suitable for back porting.

We are safe to take necessary data in ->device_alloc_chan_resources() because
we don't support generic slave configuration embedded into custom one, and thus
the only way to provide such is to use the parameter to a filter function which
is called exactly before channel resource allocation.

While here, replase BUG_ON to less noisy dev_warn() and prevent channel
allocation in case of error.

#1392979 — [PATCH 4.4 013/163] usb: xhci: fix wild pointers in xhci_mem_cleanup

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lu Baolu <baolu.lu@linux.intel.com>

commit 71504062a7c34838c3fccd92c447f399d3cb5797 upstream.

This patch fixes some wild pointers produced by xhci_mem_cleanup.
These wild pointers will cause system crash if xhci_mem_cleanup()
is called twice.

Details are available at http://kerneltests.org/builders.

The failures are all build failures.

drivers/spi/spi-rockchip.c: In function 'rockchip_spi_prepare_dma':
drivers/spi/spi-rockchip.c:458:19: error: 'struct dma_slave_caps' has no member named 'max_burst'
drivers/spi/spi-rockchip.c:478:19: error: 'struct dma_slave_caps' has no member named 'max_burst'

Culprit is "spi: rockchip: modify DMA max burst to 1". That patch
would also require commit 6d5bbed30f89 ("dmaengine: core: expose
max burst capability to clients"), which unfortunately does not
apply cleanly.

Thanks for this, I've now dropped this patch from the tree.

Compiled and booted on my test system. No dmesg regressions.
