[PATCH RFC 0/6] ALSA: Fix UAF with delayed kobj release
by Takashi Iwai 18 Aug '23

18 Aug '23

Hi, this is a test patch set for addressing the UAF problems with delayed kobj releases reported by Curtis: https://lore.kernel.org/r/20230801171928.1460120-1-cujomalainey@chromium.org The patch introduced a simple helper for allocating memory with a refcount, and converts the card object, control, PCM and compress objects with the new type. With the refcount, the actual memory release is delayed until all referrer are gone. It's just a RFC and only lightly tested. I myself am not sure whether this is the best way to go. It might be better to take Curtis' approach, just converting the device to its own allocation, too. (But I don't know whether Curtis' patch set covers all cases -- can still be a UAF of card_dev due to devres vs kobj release?) thanks, Takashi === Takashi Iwai (6): ALSA: core: Introduced referenced memory allocator ALSA: core: Fix potential UAF by delayed kobject release of card_dev ALSA: core: Associate memory reference with device initialization ALSA: pcm: Release memory with reference ALSA: control: Reference card by ctl_dev ALSA: compress: Reference card by the device include/sound/core.h | 7 ++- sound/core/compress_offload.c | 2 +- sound/core/control.c | 2 +- sound/core/hwdep.c | 2 +- sound/core/init.c | 105 +++++++++++++++++++++++++++------ sound/core/pcm.c | 6 +- sound/core/rawmidi.c | 2 +- sound/core/seq/seq_clientmgr.c | 2 +- sound/core/timer.c | 2 +- 9 files changed, 101 insertions(+), 29 deletions(-) -- 2.35.3

[PATCH v2 01/11] ASoC: dt-bindings: Add common sound card properties
by Krzysztof Kozlowski 18 Aug '23

18 Aug '23

Almost every board machine / sound cards has "audio-routing" and "model" properties, so move them to common schema to have only one definition of these properties. For amlogic,gx-sound-card, drop the minItems: 2 from the "audio-routing", because any limit here - lower or upper- is rather meaningless. This will also fix `dtbs_check` warnings like: meson-gxm-s912-libretech-pc.dtb: sound: audio-routing: ['AU2 INL', 'ACODEC LOLN', 'AU2 INR', 'ACODEC LORN', '7J4-14 LEFT', 'AU2 OUTL', '7J4-11 RIGHT', 'AU2 OUTR'] is too long Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno(a)collabora.com> Reviewed-by: Rob Herring <robh(a)kernel.org> Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski(a)linaro.org> --- Changes in v2: 1.

[PATCH 00/12] ASoC: dt-bindings: Add sound-card-common.yaml
by Krzysztof Kozlowski 18 Aug '23

18 Aug '23

Hi, Almost every board machine / sound cards has "audio-routing" and "model" properties, so we can make things simpler by introducing one common binding. It is also expected that given property has only one definition. If the patchset looks good, then the next steps will be: 1. Convert more vendor audio-routing properties to audio-routing, 2. Add dai-links children to common binding.

[PATCH v1] ALSA: hda: cs35l41: Support systems with missing _DSD properties
by Stefan Binding 18 Aug '23

18 Aug '23

Some systems using CS35L41 with HDA were released without some required _DSD properties in ACPI. To support these special cases, add an api to configure the correct properties for systems with this issue. This initial commit moves the no _DSD support for Lenovo Legion Laptops (CLSA0100, CLSA0101) into a new framework which can be extended to support additional laptops in the future.
