Each OSS PCM plugins allocate its internal buffer per pre-calculation of the max buffer size through the chain of plugins (calling src_frames and dst_frames callbacks). This works for most plugins, but the rate plugin might behave incorrectly. The calculation in the rate plugin involves with the fractional position, i.e. it may vary depending on the input position. Since the buffer size pre-calculation is always done with the offset zero, it may return a shorter size than it might be; this may result in the out-of-bound access as spotted by fuzzer. This patch addresses those possible buffer overflow accesses by simply setting the upper limit per the given buffer size for each plugin before src_frames() and after dst_frames() calls.

There's a few things like the operation callback addition for rt1015 and the meson reset addition which add small new bits of functionality to fix non-working systems, they're all very small and for parts of newly added functionality.

The commit e894efef ("ASoC: core: add support to card rebind") allows to rebind the sound card after a rebind of one of its component. With this commit, the sound card is actually rebound, but may be no more functional. The following problems have been seen with STM32 SAI driver. 1) DMA channel is not requested: With the sound card rebind the simplified call sequence is: stm32_sai_sub_probe snd_soc_register_component snd_soc_try_rebind_card snd_soc_instantiate_card devm_snd_dmaengine_pcm_register The problem occurs because the pcm must be registered, before snd_soc_instantiate_card() is called. Modify SAI driver, to change the call sequence as follows: stm32_sai_sub_probe devm_snd_dmaengine_pcm_register snd_soc_register_component snd_soc_try_rebind_card 2) DMA channel is not released: dma_release_channel() is not called when devm_dmaengine_pcm_release() is executed. This occurs because SND_DMAENGINE_PCM_DRV_NAME component, has already been released through devm_component_release(). devm_dmaengine_pcm_release() should be called before devm_component_release() to avoid this problem. Call snd_dmaengine_pcm_unregister() and snd_soc_unregister_component() explicitly from SAI driver, to have the right sequence. Signed-off-by:

commit c2caa4da ("ASoC: Fix widget powerdown on shutdown") added a set of the power state during snd_soc_dapm_shutdown to ensure the widgets powered off. However, when commit 39eb5fd1 ("ASoC: dapm: Delay w->power update until the changes are written") added the new_power member of the widget structure, to differentiate between the current power state and the target power state, it did not update the shutdown to use the new_power member. As new_power has not updated it will be left in the state set by the last DAPM sequence, ie. 1 for active widgets. So as the DAPM sequence for the shutdown proceeds it will turn the widgets on (despite them already being on) rather than turning them off.

Some code in HD-audio driver calls snprintf() in a loop and still expects that the return value were actually written size, while snprintf() returns the expected would-be length instead. When the given buffer limit were small, this leads to a buffer overflow. Use scnprintf() for addressing those issues. It returns the actually written size unlike snprintf().

The rawmidi state flags (opened, append, active_sensing) are stored in bit fields that can be potentially racy when concurrently accessed without any locks. Although the current code should be fine, there is also no any real benefit by keeping the bitfields for this kind of short number of members. This patch changes those bit fields flags to the simple bool fields. There should be no size increase of the snd_rawmidi_substream by this change.

snd_seq_check_queue() passes the current tick and time of the given queue as a pointer to snd_seq_prioq_cell_out(), but those might be updated concurrently by the seq timer update. Fix it by retrieving the current tick and time via the proper helper functions at first, and pass those values to snd_seq_prioq_cell_out() later in the loops. snd_seq_timer_get_cur_time() takes a new argument and adjusts with the current system time only when it's requested so; this update isn't needed for snd_seq_check_queue(), as it's called either from the interrupt handler or right after queuing. Also, snd_seq_timer_get_cur_tick() is changed to read the value in the spinlock for the concurrency, too.

The queue flags are represented in bit fields and the concurrent access may result in unexpected results. Although the current code should be mostly OK as it's only reading a field while writing other fields as KCSAN reported, it's safer to cover both with a proper spinlock protection. This patch fixes the possible concurrent read by protecting with q->owner_lock. Also the queue owner field is protected as well since it's the field to be protected by the lock itself.

The commit 66f2d19f ("ALSA: pcm: Fix memory leak at closing a stream without hw_free") tried to fix the regression wrt the missing hw_free call at closing without SNDRV_PCM_IOCTL_HW_FREE ioctl. However, the code change dropped mistakenly the state check, resulting in calling hw_free twice when SNDRV_PCM_IOCTL_HW_FRE got called beforehand. For most drivers, this is almost harmless, but the drivers like SOF show another regression now. This patch adds the state condition check before calling do_hw_free() at releasing the stream for avoiding the double hw_free calls.
