Update the documentation about the PCM copy callbacks. The update was kept minimalistic, just correcting the use of copy_user ops with the single copy ops, and drop/update the text mentioning the copy_kernel. Link: https://lore.kernel.org/r/20230815190136.8987-24-tiwai@suse.deSigned-off-by:

Along with the conversion to PCM copy ops, use the iov_iter for the pointer to be passed to the dmaengine process callback, too. It avoids the direct reference of iter_iov_addr(), and it can potentially help for the drivers to access memory properly (although both atmel and stm drivers don't use the given buffer address at all for now).

This patch converts the ASoC dmaenging driver code to use the new unified PCM copy callback. It's a straightforward conversion from *_user() to *_iter() variants. The process callback is still using the direct pointer as of now, but it'll be converted in the next patch. Note that copy_from/to_iter() returns the copied bytes, hence the error condition is adjusted accordingly. Reviewed-by:

This patch converts the mediatek BT SCO driver code to use the new unified PCM copy callback. It's a straightforward conversion from *_user() to *_iter() variants. As copy_form/to_iter() updates the internal offset at each read/write, we can drop the cur_*_idx counter in the loop, too. Note that copy_from/to_iter() returns the copied bytes, hence the error condition is adjusted accordingly. Reviewed-by:

For following the ALSA PCM core change, a new PCM copy ops is added toe ASoC component framework: snd_soc_component_driver receives the copy ops, and snd_soc_pcm_component_copy() helper is provided. This also fixes a long-standing potential bug where the ASoC driver covers only copy_user PCM callback and misses the copy from kernel pointers (such as OSS PCM layer), too. As of this patch, the old copy_user is still kept, but it'll be dropped later after all drivers are converted. Reviewed-by:

This patch converts the SB Emu8000 driver code to use the new unified PCM copy callback. The conversion is a bit complicated because of many open code in emu8000_pcm.c. GET_VAL() and LOOP_WRITE() macros were rewritten / simplified with copy_from_iter(). As copy_from_iter() updates the internal offset value, we can drop the corresponding part, too.

iov_iter is a universal interface to copy the data chunk from/to user-space and kernel in a unified manner. This API can fit for ALSA PCM copy ops, too; we had to split to copy_user and copy_kernel in the past, and those can be unified to a single ops with iov_iter. This patch adds a new PCM copy ops that passes iov_iter for copying both kernel and user-space in the same way. This patch touches only the ALSA PCM core part, and the actual users will be replaced in the following patches. The expansion of iov_iter is done in the PCM core right before calling each copy callback. It's a bit suboptimal, but I took this now as it's the most straightforward replacement. The more conversion to iov_iter in the caller side is a TODO for future. As of now, the old copy_user and copy_kernel ops are still kept. Once after all users are converted, we'll drop the old copy_user and copy_kernel ops, too. Link: https://lore.kernel.org/r/20230815190136.8987-3-tiwai@suse.deSigned-off-by:

The code supports realtek codec as the primary codec.

Like control and PCM devices, it's better to avoid the embedded struct device for hwdep (although it's more or less well working), too. Change it to allocate via snd_device_alloc(), and free the memory at the common snd_hwdep_free(). Reviewed-by:

So far we use the embedded struct device for each PCM substreams in struct snd_pcm. This may result in UAF when the delayed kobj release is used; each corresponding struct device is still accessed at the (delayed) device release, while the snd_pcm object may be already gone. As a workaround, detach the struct device from the snd_pcm object by allocating via the new snd_device_alloc() helper. A caveat is that we store the PCM substream pointer to drvdata since the device resume and others require the access to it. This patch is based on the fix Curtis posted initially. In this patch, the changes are split and use the new helper function instead. Link: https://lore.kernel.org/r/20230801171928.1460120-1-cujomalainey@chromium.orgReviewed-by:

Embedding the ctl_dev in the snd_card object may result in UAF when the delayed kobj release is used; at the delayed kobj release, it still accesses the struct device itself while the card memory (that embeds the struct device) may be already gone. As a workaround, detach the struct device from the card object by allocating via the new snd_device_alloc() helper. The rest are just replacing ctl_dev access to the pointer.
