2020-02-19ASoC: topology: Fix memleak in soc_tplg_manifest_load()Dragos Tarcatu1-6/+6
In case of ABI version mismatch, _manifest needs to be freed as it is just a copy of the original topology manifest. However, if a driver manifest handler is defined, that would get executed and the cleanup is never reached. Fix that by getting the return status of manifest() instead of returning directly.

2019-12-10ASoC: topology: Check return value for snd_soc_add_dai_link()Dragos Tarcatu1-6/+13
snd_soc_add_dai_link() might fail. This situation occurs for instance in a very specific use case where a PCM device and a Back End DAI link are given identical names in the topology. When this happens, soc_new_pcm_runtime() fails and then snd_soc_add_dai_link() returns -ENOMEM when called from soc_tplg_fe_link_create(). Because of that, the link will not get added into the card list, so any attempt to remove it later ends up in a panic. Fix that by checking the return status and free the memory in case of an error.

But in reality, these are very similar but different implementation. We shouldn't have duplicated and confusing implementation. snd_soc_register_dai() is now used from topology. But to reduce duplicated code, it should be used from _dais(), too. Because of topology side specific reason, it is calling snd_soc_dapm_new_dai_widgets(), but it is not needed _dais() side.

The control values and texts of the enum kcontrol associated with a widget need to be freed when the widget is removed. However, both struct snd_soc_dapm_widget and struct soc_enum contain a dobj member, which resulted in a confusion. The existing code generates a null pointer dereference by attempting to free the values and texts from the dobj which belongs to the widget instead of the dobj belonging to the enum kcontrol. The suggested fix is to use the correct dobj member (se->dobj) of the enum kcontrol.

2018-09-05ASoC: dapm: Move error handling to snd_soc_dapm_new_control_unlockedCharles Keepax1-11/+0
Currently DAPM has a lot of similar code to handle errors from snd_soc_dapm_new_control_unlocked, and much of this code does not really accurately reflect what the function returns. Firstly, most places will check for a return value of -EPROBE_DEFER and silence any error messages in that case. The one notable exception here being dapm_kcontrol_data_alloc which does currently print any error messages in the case of snd_soc_dapm_new_control_unlocked returning NULL or an error. Additionally the error prints being silenced in these case are redundant as snd_soc_dapm_new_control_unlocked can only return -EPROBE_DEFER or NULL when failing. Secondly, most places will treat a return value of NULL as an -ENOMEM. This is not correct either since any error except EPROBE_DEFER will cause a return value of NULL from snd_soc_dapm_new_control_unlocked. Centralise this handling and the error messages within snd_soc_dapm_new_control_unlocked and update the callers to simply check IS_ERR and return. Note that this update is slightly simpler in the case of dapm_kcontrol_data_alloc where that is fairly close to the handling that was already in place.

2018-06-12treewide: kzalloc() -> kcalloc()Kees Cook1-1/+1
The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

2018-06-01ASoC: topology: Improve backwards compatibility with v4 topology filesGuenter Roeck1-2/+5
Commit dc31e741db49 ("ASoC: topology: ABI - Add the types for BE DAI") introduced sound topology files version 5. Initially, this change made the topology code incompatible with v4 topology files. Backwards compatibility with v4 configuration files was subsequently added with commit 288b8da7e992 ("ASoC: topology: Support topology file of ABI v4"). Unfortunately, backwards compatibility was never fully implemented. First, the manifest size in (Skylake) v4 configuration files is set to 0, which causes manifest_new_ver() to bail out with error messages similar to the following. snd_soc_skl 0000:00:1f.3: ASoC: invalid manifest size snd_soc_skl 0000:00:1f.3: tplg component load failed-22 snd_soc_skl 0000:00:1f.3: Failed to init topology! snd_soc_skl 0000:00:1f.3: ASoC: failed to probe component -22 skl_n88l25_m98357a skl_n88l25_m98357a: ASoC: failed to instantiate card -22 skl_n88l25_m98357a: probe of skl_n88l25_m98357a failed with error -22 After this problem is fixed, the following error message is seen instead. snd_soc_skl 0000:00:1f.3: ASoC: old version of manifest snd_soc_skl 0000:00:1f.3: Invalid descriptor token 1093938482 snd_soc_skl 0000:00:1f.3: ASoC: failed to load widget media0_in cpr 0 snd_soc_skl 0000:00:1f.3: tPlg component load failed-22 This message is seen because backwards compatibility for loading widgets was never implemented. The lack of audio support when running the upstream kernel on recent Chromebooks has been reported in various forums, and can be traced back to this problem. Attempts to fix the problem, usually by providing v5 configuration files, were only partially successful. Let's implement backward compatibility properly to solve the problem for good.
