Merge series "ASoC: topology: fix use-after-free when removing components" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>: This patchset fixes a memory allocation issue and removes a 100% reproducible use-after-free report thrown by KASAN in automated module removal tests across multiple platforms. All the credit goes to Bard Liao for root-causing the issue. DAIs may be registered at the same time as a component, or when the topology is loaded. This two-step registration causes the memory for topology-based DAIs to allocated last, and conversely to be released first by devres, before the component is released and the DAIs removed from the component DAI list with snd_soc_unregister_dais(). When we remove a component, by the time we walk through its dai list to unregister all dais, the dais allocated by the topology have been freed already by devres and the list is corrupted with pointers that are no longer valid. The suggestion is to add an explicit devm_ based registration for topology-based dais, so that each dai is cleanly removed from the component dai list in the release operation before devres releases the allocated memory.

Port commit 6d011d50 ("ALSA: hda: Clear RIRB status before reading WP") from legacy HDA driver to fix the get response timeout issue. Current SOF driver does not suffer from this issue because sync write is enabled in hda_init. The issue will come back if the sync write is disabled for some reason. Signed-off-by:

soc_dpcm_fe_runtime_update() is called for all dailinks, and we want to first discard all back-ends, then deal with front-ends. The existing code first reports an error with multi-cpu front-ends, and that check needs to be moved after we know that we are dealing with a front-end.

Use devm_ to avoid use-after-free KASAN reports and simplify error handling. Signed-off-by:
-
Pierre-Louis Bossart authored
The registration of DAIs may be done at two distinct times, once during a component registration and later when loading a topology. Since devm_ managed resources are freed in the reverse order they were allocated, when a component starts unregistering DAIs by walking through the DAI list, the memory allocated for the topology-registered DAIs was freed already, which leads to 100% reproducible KASAN use-after-free reports. This patch suggests a new devm_ function to force the DAI list to be updated prior to freeing the memory chunks referenced by the list pointers. Suggested-by:

With EDMA, there is two dma channels can be used for dev_to_dev, one is from ASRC, one is from another peripheral (ESAI or SAI). If we select the dma channel of ASRC, there is an issue for ideal ratio case, the speed of copy data is faster than sample frequency, because ASRC output data is very fast in ideal ratio mode. So it is reasonable to use the dma channel of Back-End peripheral. then copying speed of DMA is controlled by data consumption speed in the peripheral FIFO, Signed-off-by:

Bard Liao authored
Additional checks for valid DAIs expose a corner case, where existing BE dailinks get modified, e.g. HDMI links are tagged with dpcm_capture=1 even if the DAIs are for playback. This patch makes those changes conditional and flags configuration issues when a BE dailink is has no_pcm=0 but dpcm_playback or dpcm_capture=1 (which makes no sense). As discussed on the alsa-devel mailing list, there are redundant flags for dpcm_playback, dpcm_capture, playback_only, capture_only. This will have to be cleaned-up in a future update. For now only correct and flag problematic configurations. Fixes: 218fe9b7 ("ASoC: soc-core: Set dpcm_playback / dpcm_capture") Suggested-by:

We already have bit field to control snd_soc_card. Let's add "probed" field on it instead of local variable. One note here is that soc_cleanup_card_resources() will be called as (A) formal cleanup or as (B) error handling, thus, it needs to distinguish these. In (A) case, card will have "instantiated" flag if all probe callback functions were called without error. Thus, snd_soc_unbind_card() is using it to judging card was probed. But this this patch removes it, because it is no longer needed. Signed-off-by:
