The DAI counting code doesn't propagate errors when the number of maximum links is exceeded, which causes subsequent initialization code to continue to run and that eventually leads to memory corruption with the code trying to access memory that is out of bounds. Fix this by propagating errors when the maximum number of links is reached, which ensures that the driver fails to load and prevents the memory corruption.

soc_pcm_params_symmetry() checks CPU / Codec symmetry. Unfortunately there was bug on it (= A) which didn't check Codec. But is back by (B). A: v5.7: commit c840f769 ("ASoC: soc-pcm: Merge for_each_rtd_cpu/codec_dais()") B: v5.12: commit 3a906721 ("ASoC: soc-pcm: cleanup soc_pcm_params_symmetry()") In total, old - v5.6 (= Generation-1): symmetric_rate : DAI_Link / CPU / Codec symmetric_channels : DAI_Link / CPU / Codec symmetric_sample_bits : DAI_Link / CPU / Codec v5.7 - v5.11 (= Generation-2): (= because of bug by (A)) symmetric_rate : DAI_Link / CPU symmetric_channels : DAI_Link / CPU / Codec symmetric_sample_bits : DAI_Link / CPU / Codec v5.12 - (= Generation-3): (= back by (B)) symmetric_rate : DAI_Link / CPU / Codec symmetric_channels : DAI_Link / CPU / Codec symmetric_sample_bits : DAI_Link / CPU / Codec OTOH, we can use DPCM which is configured by FE / BE. Both FE / BE uses dummy-DAI. FE: CPU <-> dummy-DAI BE: dummy-DAI <-> Codec One note is that we can use .be_hw_params_fixup in DPCM case. This means BE settings might be fixuped/updated by FE. This feature is used for example on MIXer case. It can be happen not only for rate, but for channels/sample_bits too. Because of these reasons, below issue happen on Generation-1 / Generation-3, if... 1) Sound Card used DPCM 2) It exchanges rate to 48kHz by using .be_hw_params_fixup() 3) Codec had symmetric_rate = 1 I didn't confirm, but maybe same things happen if it exchanged channels/sample_bits at Generation-1/2/3 too. # aplay 44100.wav # aplay 44100.wav => [kernel] be.ak4613-hifi: ASoC: unmatched rate symmetry: snd-soc-dummy-dai:44100 - soc_pcm_params_symmetry:48000 [kernel] be.ak4613-hifi: ASoC: hw_params BE failed -22 [kernel] fe.rsnd-dai.0: ASoC: hw_params BE failed -22 aplay: set_params:1407: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 32 CHANNELS: 2 RATE: 44100 PERIOD_TIME: (23219 23220) PERIOD_SIZE: 1024 PERIOD_BYTES: 4096 PERIODS: 4 BUFFER_TIME: (92879 92880) BUFFER_SIZE: 4096 BUFFER_BYTES: 16384 TICK_TIME: 0 soc_pcm_params_symmetry() checks by below if (symmetry) for_each_rtd_cpu_dais(rtd, i, cpu_dai) if (cpu_dai->xxx && cpu_dai->xxx != d.xxx) { dev_err(rtd->dev, "..."); return -EINVAL; } Because of above reason 3) (= Codec had symmetric_rate = 1) BE can't ignore "if (symmetric)". At 1st aplay, soc_pcm_params_symmetry() ignores it, because dummy-DAI->rate is 0. After this check, each DAI sets/keep settings. In above sample case, BE gets 48000 and FE gets 44100, and it happen BE -> FE order. Because DPCM is sharing *same* dummy-DAI, dummy-DAI sets as 48000 by BE, and is overwrote by 44100 by FE. This settings never be cleaned (= a) after 1st aplay, because dummy-DAI is used from FE/BE, never be last user (b). static int soc_pcm_hw_clean(...) { ... for_each_rtd_dais(rtd, i, dai) { ... (b) if (snd_soc_dai_active(dai) == 1) (a) soc_pcm_set_dai_params(dai, NULL); ... } ... } At 2nd aplay, BE gets 48000 but dummy-DAI is keeping 44100, soc_pcm_params_symmetry() checks will fail.

__soc_pcm_params_symmetry() macro is using "name" as parameter which will be exchanged to rate/channles/sample_bit, like below dai->name => dai->rate dai->name => dai->channels dai->name => dai->sample_bit But, dai itself has "name". This means 1) It is very confusable naming 2) It can't use dai->name This patch use "xxx" instead of "name" Signed-off-by:

A DAI link has 3 components: * CPU * platform * codec(s) A component is specified via: * name * of_node * dai_name In order to avoid confusion when building a sound card we disallow matching by both name and of_node (1). soc_check_tplg_fes allows overriding certain BE links by overriding BE link name. This doesn't work well if BE link was specified via DT, because we end up with a link with both name and of_node specified which is conflicting with (1). In order to fix this we need to: * override of_node if component was specified via DT * override name, otherwise. Signed-off-by:

Current rsnd needs to call .prepare (P) for clock settings, .trigger for playback start (S) and stop (E). It should be called as below from SSI point of view. P -> S -> E -> P -> S -> E -> ... But, if you used MIXer, below case might happen (2) 1: P -> S ---> E -> ... 2: P ----> S -> ... (1) (3) P(1) setups clock, but E(2) resets it. and starts playback (3). In such case, it will reports "SSI parent/child should use same rate". rsnd_ssi_master_clk_start() which is the main function at (P) was called from rsnd_ssi_init() (= S) before, but was moved by below patch to rsnd_soc_dai_prepare() (= P) to avoid using clk_get_rate() which shouldn't be used under atomic context. commit 4d230d12 ("ASoC: rsnd: fixup not to call clk_get/set under non-atomic") Because of above patch, rsnd_ssi_master_clk_start() is now called at (P) which is for non atomic context. But (P) is assuming that spin lock is *not* used. One issue now is rsnd_ssi_master_clk_start() is checking ssi->xxx which should be protected by spin lock. After above patch, adg.c had below patch for other reasons. commit 06e8f5c8 ("ASoC: rsnd: don't call clk_get_rate() under atomic context") clk_get_rate() is used at probe() timing by this patch. In other words, rsnd_ssi_master_clk_start() is no longer using clk_get_rate() any more. This means we can call it from rsnd_ssi_init() (= S) again which is protected by spin lock. This patch re-move it to under spin lock, and solves 1. checking ssi->xxx without spin lock issue. 2. clk setting / device start / device stop race condition. Reported-by:
