2018-07-18ALSA: pcm: Nuke snd_pcm_lib_mmap_vmalloc()Takashi Iwai1-2/+0
snd_pcm_lib_mmap_vmalloc() was supposed to be implemented with somewhat special for vmalloc handling, but in the end, this turned to just the default handler, i.e. NULL. As the situation has never changed over decades, let's rip it off. Reviewed-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-07-06ALSA: pcm: Allow drivers to set R/W wait time.Liam Girdwood1-0/+1
Currently ALSA core blocks userspace for about 10 seconds for PCM R/W IO. This needs to be configurable for modern hardware like DSPs where no pointer update in milliseconds can indicate terminal DSP errors. Add a substream variable to set the wait time in ms. This allows userspace and drivers to recover more quickly from terminal DSP errors. Signed-off-by: Liam Girdwood <liam.r.girdwood@linux.intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-06-28ALSA: hda - Move in_pm accessors to HDA coreTakashi Iwai1-0/+27
The in_pm atomic in hdac_device is an important field used as a flag as well as a refcount for PM. The existing snd_hdac_power_up/down helpers already refer to it in the HD-audio core code, while the code to actually setting the value (atomic_inc() / _dec()) is open-coded in HDA legacy side, which is hard to find. This patch adds the helper functions to set/reset the in_pm counter to HDA core and use them in HDA legacy side, for making it clearer who / where the PM is managed. There is no functional changes, just code refactoring. Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-05-17ALSA: core: Assure control device to be registered at lastTakashi Iwai1-1/+1
The commit 289ca025ee1d ("ALSA: Use priority list for managing device list") changed the way to register/disconnect/free devices via a single priority list. This helped to make behavior consistent, but it also changed a slight behavior change: namely, the control device is registered earlier than others, while it was supposed to be the very last one. I've put SNDRV_DEV_CONTROL in the current position as the release of ctl elements often conflict with the private ctl elements some PCM or other components may create, which often leads to a double-free. But, the order of register and disconnect should be indeed fixed as expected in the early days: the control device gets registered at last, and disconnected at first. This patch changes the priority list order to move SNDRV_DEV_CONTROL as the last guy to assure the register / disconnect order. Meanwhile, for keeping the messy resource release order, manually treat the control and lowlevel devices as last freed one. Additional note: The lowlevel device is the device where a card driver creates at probe. And, we still keep the release order control -> lowlevel, as there might be link from a control element back to a lowlevel object.

2018-05-01ASoC: dai playback and capture active may be greater than 1Jerome Brunet1-2/+2
At the moment playback_active and capture_active are using only 1 bit so the maximum active count is 1. However, snd_soc_runtime_activate() may be called several time on the same dai. This happens when a dai is part of several dai_links. It is often the case for "snd-soc-dummy-dai". This is a problem if snd_soc_runtime_activate() is called an even number of times on a dai. In this case the active count overflow back to 0. As consequence, ASoC functions, such as soc_dpcm_runtime_update(), won't run correctly. Storing these usage counts on plain 'unsigned int' solves the problem.

2018-04-25ALSA: control: Hardening for potential Spectre v1Takashi Iwai1-2/+5
As recently Smatch suggested, a few places in ALSA control core codes may expand the array directly from the user-space value with speculation: sound/core/control.c:1003 snd_ctl_elem_lock() warn: potential spectre issue 'kctl->vd' sound/core/control.c:1031 snd_ctl_elem_unlock() warn: potential spectre issue 'kctl->vd' sound/core/control.c:844 snd_ctl_elem_info() warn: potential spectre issue 'kctl->vd' sound/core/control.c:891 snd_ctl_elem_read() warn: potential spectre issue 'kctl->vd' sound/core/control.c:939 snd_ctl_elem_write() warn: potential spectre issue 'kctl->vd' Although all these seem doing only the first load without further reference, we may want to stay in a safer side, so hardening with array_index_nospec() would still make sense. In this patch, we put array_index_nospec() to the common snd_ctl_get_ioff*() helpers instead of each caller. These helpers are also referred from some drivers, too, and basically all usages are to calculate the array index from the user-space value, hence it's better to cover there.

Machine drivers statically define a number of DAI links that currently cannot be changed or removed by topology. This means PCMs and platform components cannot be changed by topology at runtime AND machine drivers are tightly coupled to topology. This patch allows topology to override the machine driver DAI link config in order to reuse machine drivers with different topologies and platform components. The patch supports :- 1) create new FE PCMs with a topology defined PCM ID. 2) destroy existing static FE PCMs 3) change the platform component driver. 4) assign any new HW params fixups. The patch requires no changes to the machine drivers, but does add some platform component flags that the platform component driver can assign before loading topologies.

2018-04-16ALSA: emu10k1: Reduce GFP_ATOMIC allocationTakashi Iwai1-2/+2
The emu10k1 fx8010 code allocates each irq resource dynamically and links to the list at PCM trigger callback. Due to the nature of trigger callback, the allocation is done with GFP_ATOMIC, hence it may fail more often. Moreover, the irq resource isn't big at all, and using the kmalloc for this won't save many bytes, either. This patch removes the dynamic allocation and embeds the irq resource into struct snd_emu10k1_fx8010_pcm.irq field instead of keeping a pointer. As a result, it simplifies the code and removes the unnecessary GFP_ATOMIC usage. Signed-off-by: Takashi Iwai <tiwai@suse.de>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Updates for v4.17 This is a *very* big release for ASoC. Not much change in the core but there s the transition of all the individual drivers over to components which is intended to support further core work. The goal is to make it easier to do further core work by removing the need to special case all the different driver classes in the core, many of the devices end up being used in multiple roles in modern systems. We also have quite a lot of new drivers added this month of all kinds, quite a few for simple devices but also some more advanced ones with more substantial code. - The biggest thing is the huge series from Morimoto-san which converted everything over to components. This is a huge change by code volume but was fairly mechanical - Many fixes for some of the Realtek based Baytrail systems covering both the CODECs and the CPUs, contributed by Hans de Goode. - Lots of cleanups for Samsung based Odroid systems from Sylwester Nawrocki. - The Freescale SSI driver also got a lot of cleanups from Nicolin Chen. - The Blackfin drivers have been removed as part of the removal of the architecture. - New drivers for AKM AK4458 and AK5558, several AMD based machines, several Intel based machines, Maxim MAX9759, Motorola CPCAP, Socionext Uniphier SoCs, and TI PCM1789 and TDA7419

2018-03-24ALSA: pcm: Return -EBUSY for OSS ioctls changing busy streamsTakashi Iwai1-0/+1
OSS PCM stream management isn't modal but it allows ioctls issued at any time for changing the parameters. In the previous hardening patch ("ALSA: pcm: Avoid potential races between OSS ioctls and read/write"), we covered these races and prevent the corruption by protecting the concurrent accesses via params_lock mutex. However, this means that some ioctls that try to change the stream parameter (e.g. channels or format) would be blocked until the read/write finishes, and it may take really long. Basically changing the parameter while reading/writing is an invalid operation, hence it's even more user-friendly from the API POV if it returns -EBUSY in such a situation. This patch adds such checks in the relevant ioctls with the addition of read/write access refcount. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
