commit a9960e6a293e6fc3ed414643bb4e4106272e4d0a upstream. The calculated frame size was wrong because snd_pcm_format_physical_width() actually returns the number of bits, not bytes.

2014-10-05ALSA: hda - Fix invalid pin powermap without jack detectionTakashi Iwai1-5/+12
commit 7a9744cb455e6faa287e148394b4b422a6f3c5c4 upstream. When a driver is set up without the jack detection explicitly (either by passing a model option or via a specific fixup), the pin powermap of IDT/STAC codecs is set up wrongly, resulting in the silence output. It's because of a logic failure in stac_init_power_map(). It tries to avoid creating a callback for the pins that have other auto-hp and auto-mic callbacks, but the check is done in a wrong way at a wrong time. The stac_init_power_map() should be called after creating other jack detection ctls, and the jack callback should be created only for jack-detectable widgets. This patch fixes the check in stac_init_power_map() and its callee at the right place, after snd_hda_gen_build_controls().

2014-09-05ALSA: hda/realtek - Avoid setting wrong COEF on ALC269 & coTakashi Iwai1-5/+12
commit f3ee07d8b6e061bf34a7167c3f564e8da4360a99 upstream. ALC269 & co have many vendor-specific setups with COEF verbs. However, some verbs seem specific to some codec versions and they result in the codec stalling. Typically, such a case can be avoided by checking the return value from reading a COEF. If the return value is -1, it implies that the COEF is invalid, thus it shouldn't be written. This patch adds the invalid COEF checks in appropriate places accessing ALC269 and its variants. The patch actually fixes the resume problem on Acer AO725 laptop.

A workaround is to restore the gpio data when the system resume back from s3/s4. It is safe even on the machines without this problem.

commit e24aa0a4c5ac92a171d9dd74a8d3dbf652990d36 upstream. CA0132 driver tries to reload the firmware at resume.

commit 4da63c6fc426023d1a20e45508c47d7d68c6a53d upstream. When the initialization of Intel HDMI controller fails due to missing i915 kernel symbols (e.g. HD-audio is built in while i915 is module), the driver discontinues the probe. However, since the probe was done asynchronously, the driver object still remains, thus the relevant PM ops are still called at suspend/resume. This results in the bad access to the incomplete audio card object, eventually leads to Oops or stall at PM. This patch adds the missing checks of chip->init_failed flag at each PM callback in order to fix the problem above.

2014-07-06ALSA: usb-audio: Fix races at disconnection and PCM closingTakashi Iwai3-6/+25
commit 92a586bdc06de6629dae1b357dac221253f55ff8 upstream. When a USB-audio device is disconnected while PCM is still running, we still see some race: the disconnect callback calls snd_usb_endpoint_free() that calls release_urbs() and then kfree() while a PCM stream would be closed at the same time and calls stop_endpoints() that leads to wait_clear_urbs(). That is, the EP object might be deallocated while a PCM stream is syncing with wait_clear_urbs() with the same EP. Basically calling multiple wait_clear_urbs() would work fine, also calling wait_clear_urbs() and release_urbs() would work, too, as wait_clear_urbs() just reads some fields in ep. The problem is the succeeding kfree() in snd_pcm_endpoint_free(). This patch moves out the EP deallocation into the later point, the destructor callback. At this stage, all PCMs must have been already closed, so it's safe to free the objects.

commit 883a1d49f0d77d30012f114b2e19fc141beb3e8e upstream. The ALSA control code expects that the range of assigned indices to a control is continuous and does not overflow. Currently there are no checks to enforce this. If a control with a overflowing index range is created that control becomes effectively inaccessible and unremovable since snd_ctl_find_id() will not be able to find it.

commit ac902c112d90a89e59916f751c2745f4dbdbb4bd upstream. Each control gets automatically assigned its numids when the control is created. The allocation is done by incrementing the numid by the amount of allocated numids per allocation. This means that excessive creation and destruction of controls (e.g. via SNDRV_CTL_IOCTL_ELEM_ADD/REMOVE) can cause the id to eventually overflow. Currently when this happens for the control that caused the overflow kctl->id.numid + kctl->count will also over flow causing it to be smaller than kctl->id.numid. Most of the code assumes that this is something that can not happen, so we need to make sure that it won't happen Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Acked-by: Jaroslav Kysela <perex@perex.cz> Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2014-06-26ALSA: control: Fix replacing user controlsLars-Peter Clausen1-16/+9
commit 82262a46627bebb0febcc26664746c25cef08563 upstream. There are two issues with the current implementation for replacing user controls. The first is that the code does not check if the control is actually a user control and neither does it check if the control is owned by the process that tries to remove it. That allows userspace applications to remove arbitrary controls, which can cause a user after free if a for example a driver does not expect a control to be removed from under its feed. The second issue is that on one hand when a control is replaced the user_ctl_count limit is not checked and on the other hand the user_ctl_count is increased (even though the number of user controls does not change). This allows userspace, once the user_ctl_count limit as been reached, to repeatedly replace a control until user_ctl_count overflows. Once that happens new controls can be added effectively bypassing the user_ctl_count limit. Both issues can be fixed by instead of open-coding the removal of the control that is to be replaced to use snd_ctl_remove_user_ctl(). This function does proper permission checks as well as decrements user_ctl_count after the control has been removed. Note that by using snd_ctl_remove_user_ctl() the check which returns -EBUSY at beginning of the function if the control already exists is removed. This is not a problem though since the check is quite useless, because the lock that is protecting the control list is released between the check and before adding the new control to the list, which means that it is possible that a different control with the same settings is added to the list after the check. Luckily there is another check that is done while holding the lock in snd_ctl_add(), so we'll rely on that to make sure that the same control is not added twice.

2014-06-26ALSA: control: Protect user controls against concurrent accessLars-Peter Clausen2-6/+26
commit 07f4d9d74a04aa7c72c5dae0ef97565f28f17b92 upstream. The user-control put and get handlers as well as the tlv do not protect against concurrent access from multiple threads. Since the state of the control is not updated atomically it is possible that either two write operations or a write and a read operation race against each other. Both can lead to arbitrary memory disclosure. This patch introduces a new lock that protects user-controls from concurrent access. Since applications typically access controls sequentially than in parallel a single lock per card should be fine.

2014-06-07ASoC: wm8962: Update register CLASS_D_CONTROL_1 to be non-volatileCharles Keepax2-3/+16
commit 44330ab516c15dda8a1e660eeaf0003f84e43e3f upstream. The register CLASS_D_CONTROL_1 is marked as volatile because it contains a bit, DAC_MUTE, which is also mirrored in the ADC_DAC_CONTROL_1 register. This causes problems for the "Speaker Switch" control, which will report an error if the CODEC is suspended because it relies on a volatile register. To resolve this issue mark CLASS_D_CONTROL_1 as non-volatile and manually keep the register cache in sync by updating both bits when changing the mute status.

2014-06-07ASoC: dapm: Skip CODEC<->CODEC links in connect_dai_link_widgets()Lars-Peter Clausen1-2/+5
commit ca5106ae3da0179dcee3ae21f3ea94f62e9fdb0c upstream. For CODEC to CODEC DAI links the paths are created in snd_soc_dapm_new_pcm(). Also for CODEC to CODEC links the widgets are connected cross-over via a DAI link widget, meaning that the capture widget of one CODEC will be connected to the playback widget of the other and vice versa. Whereas snd_soc_dapm_connect_dai_link_widgets() directly connects the playback widget of the CPU DAI to the playback widget of the CODEC DAI and the capture widget of the CPU DAI to the capture widget of the CODEC DAI. So not skipping CODEC<->CODEC links in snd_soc_dapm_connect_dai_link_widgets() will create incorrect connections between the two CODECs which will cause DAPM to detect active paths where there are none and unnecessarily power up widgets.

2014-06-07ALSA: hda - hdmi: Set converter channel count even without sinkAnssi Hannula1-1/+3
commit f06ab794af7055d0949b09885f79f8b493deec64 upstream. Since commit 1df5a06a ("ALSA: hda - hdmi: Fix programmed active channel count") channel count is no longer being set if monitor_present is 0. This is because setting the count was moved after the CA value is determined, which is only after the monitor_present check in hdmi_setup_audio_infoframe(). Unfortunately, in some cases, such as with a non-spec-compliant codec or with a problematic video driver, monitor_present is always 0. As a specific example, this seems to happen with gen1 ATV (SiI1390 codec), causing left-channel-only stereo playback (multi-channel playback has apparently never worked with this codec despite it reporting 8 channels, reason unknown). Simply setting converter channel count without setting the pin infoframe and channel mapping as well does not theoretically make much sense as this will just mean they are out-of-sync and multichannel playback will have a wrong channel mapping. However, adding back just setting the converter channel count even in no-monitor case is the safest change which at least fixes the stereo playback regression on SiI1390 codec. Do that.

2014-05-13ASoC: dapm: Fix widget double free with auto-disable DAPM kcontrolJarkko Nikula1-1/+0
commit 2697e4fb9209dfe1d1b24c92d254158f63d4bc8e upstream. Commit 9e1fda4ae158 ("ASoC: dapm: Implement mixer input auto-disable") is trying to free the widget it allocated by snd_soc_dapm_new_control() call in dapm_kcontrol_data_alloc() by adding kfree(data->widget) to dapm_kcontrol_free(). This is causing a widget double free with auto-disabled DAPM kcontrols in sound card unregistration because widgets are already freed before dapm_kcontrol_free() is called. Reason for that is all widgets are added into dapm->card->widgets list in snd_soc_dapm_new_control() and freed in dapm_free_widgets() during execution of snd_soc_dapm_free(). Now snd_soc_dapm_free() calls for different DAPM contexts happens before snd_card_free() call from where the call chain to dapm_kcontrol_free() begins: soc_cleanup_card_resources() soc_remove_dai_links() soc_remove_link_dais() snd_soc_dapm_free(&cpu_dai->dapm) soc_remove_link_components() soc_remove_platform() snd_soc_dapm_free(&platform->dapm) soc_remove_codec() snd_soc_dapm_free(&codec->dapm) snd_soc_dapm_free(&card->dapm) snd_card_free() snd_card_do_free() snd_device_free_all() snd_device_free() snd_ctl_dev_free() snd_ctl_remove() snd_ctl_free_one() dapm_kcontrol_free() This wasn't making harm with ordinary DAPM kcontrols since data->widget is NULL for them.
