media: au0828: fix enable and disable source audio and video inconsistencies

Enable and disable source interfaces aren't consistent in enforcing
how video and audio share the tuner resource.

Fix these issues to enforce the following rules and allow
sharing between audio and video applications.

- When DVB is streaming, audio/video/vbi/s-video/composite
should find the resource busy. DVB holds the tuner in
exclusive mode.
- When video/VBI is streaming, audio can share the tuner and vice versa.
- v4l2 allows multiple applications to open video device.
- Video applications call enable source multiple times during their
run-time. Resource should stay locked until the last application
releases it.
- A shared resource should stay in shared state and locked when it is
in use by audio and video. More than one video application is allowed
to use the tuner as long as video streaming protocol allows such usage.
Resource is released when the last video/audio application releases it.
- S-Video and Composite hold the resource in exclusive mode.

media: change au0828 to use Media Device Allocator API

Media Device Allocator API to allows multiple drivers share a media device.
This API solves a very common use-case for media devices where one physical
device (an USB stick) provides both audio and video. When such media device
exposes a standard USB Audio class, a proprietary Video class, two or more
independent drivers will share a single physical USB bridge. In such cases,
it is necessary to coordinate access to the shared resource.

Using this API, drivers can allocate a media device with the shared struct
device as the key. Once the media device is allocated by a driver, other
drivers can get a reference to it. The media device is released when all
the references are released.

Change au0828 to use Media Device Allocator API to allocate media device
with the parent usb struct device as the key, so it can be shared with the
snd_usb_audio driver.

[media] media: Protect enable_source and disable_source handler code paths

Drivers might try to access and run enable_source and disable_source
handlers when the driver that implements these handlers is clearing
the handlers during its unregister.

Fix the following race condition:

process 1 process 2

request video streaming unbind au0828
v4l2 checks if tuner is free
... ...

au0828_unregister_media_device()
... ...
(doesn't hold graph_mutex)
mdev->enable_source = NULL;
if (mdev && mdev->enable_source) mdev->disable_source = NULL;
mdev->enable_source()
(enable_source holds graph_mutex)

As shown above enable_source check is done without holding the graph_mutex.
If unbind happens to be in progress, au0828 could clear enable_source and
disable_source handlers leading to null pointer de-reference.

Fix it by protecting enable_source and disable_source set and clear and
protecting enable_source and disable_source handler access and the call
itself.

process 1 process 2

request video streaming unbind au0828
v4l2 checks if tuner is free
... ...

au0828_unregister_media_device()
... ...
(hold graph_mutex while clearing)
mdev->enable_source = NULL;
if (mdev) mdev->disable_source = NULL;
(hold graph_mutex to check and
call enable_source)
if (mdev->enable_source)
mdev->enable_source()

If graph_mutex is held to just heck for handler being null and needs to be
released before calling the handler, there will be another window for the
handlers to be cleared. Hence, enable_source and disable_source handlers
no longer hold the graph_mutex and expect callers to hold it to avoid
forcing them release the graph_mutex before calling the handlers.

[media] media: Rename graph and pipeline structs and functions

The media_entity_pipeline_start() and media_entity_pipeline_stop()
functions are renamed as media_pipeline_start() and media_pipeline_stop(),
respectively. The reason is two-fold: the pipeline struct is, rightly,
already called media_pipeline (rather than media_entity_pipeline) and what
this really is about is a pipeline. A pipeline consists of entities ---
and, well, other objects embedded in these entities.

As the pipeline object will be in the future moved from entities to pads
in order to support multiple pipelines through a single entity, do the
renaming now.

Similarly, functions operating on struct media_entity_graph as well as the
struct itself are renamed by dropping the "entity_" part from the prefix
of the function family and the data structure. The graph traversal which
is what the functions are about is not specifically about entities only
and will operate on pads for the same reason as the media pipeline.

The patch has been generated using the following command:

git grep -l media_entity |xargs perl -i -pe '
s/media_entity_pipeline/media_pipeline/g;
s/media_entity_graph/media_graph/g'

And a few manual edits related to line start alignment and line wrapping.

[media] media-device: dynamically allocate struct media_devnode

struct media_devnode is currently embedded at struct media_device.

While this works fine during normal usage, it leads to a race
condition during devnode unregister. the problem is that drivers
assume that, after calling media_device_unregister(), the struct
that contains media_device can be freed. This is not true, as it
can't be freed until userspace closes all opened /dev/media devnodes.

In other words, if the media devnode is still open, and media_device
gets freed, any call to an ioctl will make the core to try to access
struct media_device, with will cause an use-after-free and even GPF.

Fix this by dynamically allocating the struct media_devnode and only
freeing it when it is safe.

Extending the lifetime of the media_device struct is not handled well
by the core, as it will erase some data from the struct, when

While we have a fixup patch for it already, the usage of those new

[media] media: au0828 fix to clear enable/disable/change source handlers

Fix to clear enable/disable/change source handlers in the media device
when media device is unregistered in au0828_unregister_media_device().
When au0828 module is removed, snd-usb-audio shouldn't call the handlers.
Clearing will ensure snd-usb-audio won't call them once au0828 is removed.

[media] au0828: disable tuner links and cache tuner/decoder

For au0828_enable_source() to work, the tuner links should be
disabled and the tuner/decoder should be cached at au0828 struct.

While here, put dev->decoder cache together with dev->tuner, as
it makes easier to drop both latter if/when we move the enable
routines to the V4L2 core.
