2020-12-11ASoC: topology: Fix wrong size checkAmadeusz Sławiński1-2/+8
Dan reported that smatch reports wrong size check and after analysis it is confirmed that we are comparing wrong value: pointer size instead of array size. However the check itself is problematic as in UAPI header there are two fields: struct snd_soc_tplg_enum_control { (...) char texts[SND_SOC_TPLG_NUM_TEXTS][SNDRV_CTL_ELEM_ID_NAME_MAXLEN]; __le32 values[SND_SOC_TPLG_NUM_TEXTS * SNDRV_CTL_ELEM_ID_NAME_MAXLEN / 4]; the texts field is for names and the values one for values assigned to those named fields, after analysis it becomes clear that there is quite a lot overhead values than we may possibly name. So instead of changing check to ARRAY_SIZE(ec->values), as it was first suggested, use hardcoded value of SND_SOC_TPLG_NUM_TEXTS.

2020-11-04ASoC: topology: Change allocations to resource managedAmadeusz Sławiński1-131/+40
In order for topology to be resource managed, change all allocations to be resource managed: k*alloc -> devm_k*alloc kstrdup -> devm_kstrdup Exceptions where non resource managed allocation is left is soc_tplg_dapm_widget_create(), as it uses pointer to memory locally and frees it up after use, as well as soc_tplg_dapm_graph_elems_load(), which has temporary pointer to table of routes. After conversion all redundant calls in error and clean up paths were removed. Also removed some variables which become unneeded when there is no calls using them.

2020-09-17ASoC: topology: disable size checks for bytes_ext controls if neededPierre-Louis Bossart1-0/+11
When CONFIG_SND_CTL_VALIDATION is set, accesses to extended bytes control generate spurious error messages when the size exceeds 512 bytes, such as [ 11.224223] sof_sdw sof_sdw: control 2:0:0:EQIIR5.0 eqiir_coef_5:0: invalid count 1024 In addition the error check returns -EINVAL which has the nasty side effect of preventing applications accessing controls from working, e.g. root@plb:~# alsamixer cannot load mixer controls: Invalid argument It's agreed that the control interface has been abused since 2014, but forcing a check should not prevent existing solutions from working. This patch skips the checks conditionally if CONFIG_SND_CTL_VALIDATION is set and the byte array provided by topology is > 512. This preserves the checks for all other cases.

Since the beginning of the topology, the code continues to the next object even when an error is detected. The topology should be handled with an all-or-nothing design, loading a partially valid topology is a sure way to get bug reports that are difficult to deal with. Changing the behavior may break previous solutions and expose problems in topology files delivered in the past, so it's probably not wise to add this patch to stable branches without revalidation.

Function soc_tplg_dbytes_create(), calls soc_tplg_init_kcontrol() to perform additional driver specific initialization. While soc_tplg_init_kcontrol() ensures that component is valid before invoking ops->control_load, there is no such check at the end of soc_tplg_dbytes_create() where list_add() is used. Also in quite a few places, there is reference of tplg->comp->dapm or tplg->comp->card, without any checks for tplg->comp. In consequence of the above this may lead to referencing NULL pointer. This allows for removal of now unnecessary checks.

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.

If soc_tplg_link_config() fails, _link needs to be freed in case of topology ABI version mismatch. However the current code is returning directly and ends up leaking memory in this case. This patch fixes that.

2020-01-23ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization orderJaroslav Kysela1-3/+4
The code which checks the return value for snd_soc_add_dai_link() call in soc_tplg_fe_link_create() moved the snd_soc_add_dai_link() call before link->dobj members initialization. While it does not affect the latest kernels, the old soc-core.c code in the stable kernels is affected. The snd_soc_add_dai_link() function uses the link->dobj.type member to check, if the link structure is valid. Reorder the link->dobj initialization to make things work again. It's harmless for the recent code (and the structure should be properly initialized before other calls anyway). The problem is in stable linux-5.4.y since version 5.4.11 when the upstream commit 76d270364932 was applied.

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.
