commit 316e730f1d upstream.
The topology that v4l2_m2m_register_media_controller() creates for a
processing block actually created a source-to-source link and a sink-to-sink
link instead of two source-to-sink links.
Unfortunately v4l2-compliance never checked for such bad links, so this

commit 4a873f3fa5 upstream.
The do_video_ioctl() compat handler converts the compat command
codes into the native ones before processing further, but this
causes problems for 32-bit user applications that pass a command
code that matches a 64-bit native number, which will then be
handled the same way.
Specifically, this breaks VIDIOC_DQEVENT_TIME from user space
applications with 64-bit time_t, as the structure layout is
the same as the native 64-bit layout on many architectures
(x86 being the notable exception).
Change the handler to use the converted command code only for
passing into the native ioctl handler, not for deciding on the
conversion, in order to make the compat behavior match the
native behavior.
Actual support for the 64-bit time_t version of VIDIOC_DQEVENT_TIME
and other commands still needs to be added in a separate patch.

commit 3c7470b6f6 upstream.
After DMA is complete, and the device and CPU caches are synchronized,
it's still required to mark the CPU pages as dirty, if the data was
coming from the device. However, this driver was just issuing a bare
put_page() call, without any set_page_dirty*() call.
Fix the problem, by calling set_page_dirty_lock() if the CPU pages were
potentially receiving data from the device.

There's a race condition between the list_del_init in the
v4l2_ctrl_request_complete, and the list_add_tail in the
v4l2_ctrl_request_queue, since they can be called in different thread
and the requests_queued list is not protected by a lock. This can lead
to that the v4l2_ctrl_handler is still in the requests_queued list while
the request_is_queued is already set to false, which would cause
use-after-free if the v4l2_ctrl_handler is later released.
Fix this by locking the ->lock of main_hdl (which is the owner of the
requests_queued list) when doing list operations on the
->requests_queued list.

The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of
the added fwnode, relying on the caller to handle that instead, in essence
putting the fwnode to be added if there was an error.
As the reference is eventually released during the notifier cleanup, this
is not intuitive nor logical. Improve this by always getting a reference
when the function succeeds, and the caller releasing the reference when it
does not *itself* need it anymore.
Luckily, perhaps, there were just a handful of callers using the function.

When reaching the end of stream, V4L2 m2m clients may expect the
V4L2_EOS_EVENT. Although the V4L2_EOS_EVENT is deprecated behavior,
drivers must signal that event before dequeuing the buffer that has the
V4L2_BUF_FLAG_LAST flag set.
If a driver queues the V4L2_EOS_EVENT event and returns the buffer after
the check for events but before the check for buffers, vb2_m2m_poll()
will signal that the buffer with V4L2_BUF_FLAG_LAST can be read but not
that the V4L2_EOS_EVENT is available.
Split the check for buffers into a separate function and check for
available buffers before checking for events. This ensures that if
vb2_m2m_poll() signals POLLIN | POLLRDNORM for the V4L2_BUF_FLAG_LAST
buffer, it signals POLLPRI for the V4L2_EOS_EVENT, too.

Check if sd->entity.num_pads is non-zero instead since that doesn't depend
on mdev.
