[alsa-devel] [PATCH 1/7] ASoC: SOF: fix an Oops, caused by invalid topology

[Pierre-Louis Bossart]

From: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

It is possible to create invalid topology that will cause a kernel
Oops when trying to allocate buffers for a NULL substream.
Specifically such an Oops was caused by a topology, where a DAI on a
capture pipeline was referencing the PCM ID from a playback pipeline.
Fix the Oops by explicitly checking for NULL.

[alsa-devel] [PATCH 3/7] ASoC: SOF: core: release resources on errors in probe_continue

[Pierre-Louis Bossart]

The initial intent of releasing resources in the .remove does not work
well with HDaudio codecs. If the probe_continue() fails in a work
queue, e.g. due to missing firmware or authentication issues, we don't
release any resources, and as a result the kernel oopses during
suspend operations.

The suggested fix is to release all resources during errors in
probe_continue(), and use fw_state to track resource allocation
state, so that .remove does not attempt to release the same
hardware resources twice. PM operations are also modified so that
no action is done if DSP resources have been freed due to
an error at probe.

[alsa-devel] [PATCH 4/7] ASoC: SOF: trace: fix unconditional free in trace release

[Pierre-Louis Bossart]

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

Check if DMA pages were successfully allocated in initialization
before calling free. For many types of memory (like sgbufs)
the extra free is harmless, but not all backends track allocation
state, so add an explicit check.

[alsa-devel] [PATCH 7/7] ASoC: Intel: consistent HDMI codec probing code

[Pierre-Louis Bossart]

From: Guennadi Liakhovetski <guennadi.liakhovetski@linux.intel.com>

Multiple Intel ASoC machine drivers repeat the same pattern in their
.late_probe() methods: they first check whether the common HDMI codec
driver is used, if not, they proceed by linking the legacy HDMI
driver to each HDMI port. While doing that they use some
inconsistent code:

1. after the loop they check, whether the list contained at least one
   element and if not, they return an error. However, the earlier
   code to use the common HDMI driver uses the first element of the
   same list without checking. To fix this we move the check to the
   top of the function.

2. some of those .late_probe() implementations execute code, only
   needed for the common HDMI driver, before checking, whether the
   driver is used. Move the code to after the check.

3. Some of those functions also perform a redundant initialisation of
   the "err" variable.

This patch fixes those issues.

This deserves for Cc to stable, as the bug already hits on both 5.4
and 5.5 kernels.

Patch 2 would need to be Cc:'ed to stable as well, otherwise this patch3 
will not apply.

[alsa-devel] Applied "ASoC: Intel: consistent HDMI codec probing code" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: consistent HDMI codec probing code

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: Intel: consistent HDMI codec probing code

Multiple Intel ASoC machine drivers repeat the same pattern in their
.late_probe() methods: they first check whether the common HDMI codec
driver is used, if not, they proceed by linking the legacy HDMI
driver to each HDMI port. While doing that they use some
inconsistent code:

1. after the loop they check, whether the list contained at least one
   element and if not, they return an error. However, the earlier
   code to use the common HDMI driver uses the first element of the
   same list without checking. To fix this we move the check to the
   top of the function.

2. some of those .late_probe() implementations execute code, only
   needed for the common HDMI driver, before checking, whether the
   driver is used. Move the code to after the check.

3. Some of those functions also perform a redundant initialisation of
   the "err" variable.

This patch fixes those issues.

The patch

   ASoC: SOF: trace: fix unconditional free in trace release

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Subject: [PATCH] ASoC: SOF: trace: fix unconditional free in trace release

Check if DMA pages were successfully allocated in initialization
before calling free. For many types of memory (like sgbufs)
the extra free is harmless, but not all backends track allocation
state, so add an explicit check.

Subject: [PATCH] ASoC: SOF: core: release resources on errors in
 probe_continue

The initial intent of releasing resources in the .remove does not work
well with HDaudio codecs. If the probe_continue() fails in a work
queue, e.g. due to missing firmware or authentication issues, we don't
release any resources, and as a result the kernel oopses during
suspend operations.

The suggested fix is to release all resources during errors in
probe_continue(), and use fw_state to track resource allocation
state, so that .remove does not attempt to release the same
hardware resources twice. PM operations are also modified so that
no action is done if DSP resources have been freed due to
an error at probe.

Subject: [PATCH] ASoC: SOF: fix an Oops, caused by invalid topology

It is possible to create invalid topology that will cause a kernel
Oops when trying to allocate buffers for a NULL substream.
Specifically such an Oops was caused by a topology, where a DAI on a
capture pipeline was referencing the PCM ID from a playback pipeline.
Fix the Oops by explicitly checking for NULL.
