2019-04-08ASoC: topology: Use the correct dobj to free enum control values and textsRanjani Sridharan1-3/+4
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.

2019-02-04ASoC: topology: unload physical dai link in removeBard liao1-0/+32
soc_tplg_link_config() will find the physical dai link and call soc_tplg_dai_link_load() to load the BE dai link. Currently remove_link() is only used to remove the FE dai link which is created by the topology. The BE dai link cannot however be unloaded in snd_soc_tplg_component _remove(), which is problematic if anything needs to be released or reinitialized. This patch aligns the definitions of dynamic types with the existing UAPI and adds a new remove_backend_link() routine to unload the the BE dai link when snd_soc_tplg_component_remove() is invoked.

2019-02-02ASoC: topology: fix oops/use-after-free case with dai driverGuennadi Liakhovetski1-0/+5
rmmod/modprobe tests expose a kernel oops when accessing the dai driver pointer. This comes from the topology design which operates in multiple passes. Each object removal happens at a specific iteration, and the code checks for the iteration (order) number after the memory containing the order was freed. Fix this be clearing a reference to the dai driver and check its validity to avoid dereferences.

2019-01-29ASoC: topology: modify dapm route loading routine and add dapm route unloadingRanjani Sridharan1-16/+86
struct snd_soc_dapm_route has been modified to be a dynamic object so that it can be used to save driver specific data while parsing topology and clean up driver-specific data during driver unloading. This patch makes the following changes to accomplish the above: 1. Set the dobj member of snd_soc_dapm_route during the SOC_TPLG_PASS_GRAPH pass of topology parsing. 2. Add the remove_route() routine that will be called while removing all dynamic objects from the component driver.

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.

Clock gating parameter is a part of `dai_fmt`. It is supported by `alsa-lib` when creating a topology binary file, but ignored by kernel when loading this topology file. After applying this commit, the clock gating parameter is not ignored any more. This solution is backwards compatible. The existing behaviour is not broken, because by default the parameter value is 0 and is ignored. snd_soc_tplg_hw_config.clock_gated = 0 => no effect snd_soc_tplg_hw_config.clock_gated = 1 => SND_SOC_DAIFMT_GATED snd_soc_tplg_hw_config.clock_gated = 2 => SND_SOC_DAIFMT_CONT For example, the following config, based on alsa-lib/src/conf/topology/broadwell/broadwell.conf, is now supported: ~~~~ SectionHWConfig."CodecHWConfig" { id "1" format "I2S" # physical audio format. pm_gate_clocks "true" # clock can be gated } SectionLink."Codec" { # used for binding to the physical link id "0" hw_configs [ "CodecHWConfig" ] default_hw_conf_id "1" } ~~~~ Signed-off-by: Kirill Marinushkin <k.marinushkin@gmail.com> Reviewed-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.de> Cc: Mark Brown <broonie@kernel.org> Cc: Pan Xiuli <xiuli.pan@linux.intel.com> Cc: Liam Girdwood <liam.r.girdwood@linux.intel.com> Cc: linux-kernel@vger.kernel.org Cc: alsa-devel@alsa-project.org Signed-off-by: Mark Brown <broonie@kernel.org>

2017-09-14ASoC: topology: Fix a potential memory leak in 'soc_tplg_dapm_widget_denum_create()'Christophe JAILLET1-1/+1
If this sanity check fails, we must free the memory that has already been allocated. So we must go to 'err' as in the other error handling parth of this function.

2017-09-14ASoC: topology: Fix a potential NULL pointer dereference in 'soc_tplg_dapm_widget_denum_create()'Christophe JAILLET1-0/+3
if 'se = kzalloc()' fails in the 'for' loop, we will branch to 'err'. But in this case, 'kc[i].private_value' will still be NULL. A NULL pointer dereference will then occur is the error handling path. In such a case, it is safe to just 'continue' in order to skip this entry and free the other ones.

2017-06-30ASoC: topology: Fix usage of SND_SOC_TPLG_INDEX_ALL during loadLiam Girdwood1-1/+1
SND_SOC_TPLG_INDEX_ALL is used by drivers to tell the core to load all topology component indexes, not just the index in the header. Fix this so that SND_SOC_TPLG_INDEX_ALL will load all components no matter their index. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
