2018-03-08ALSA: seq: Don't allow resizing pool in useTakashi Iwai
This is a fix for a (sort of) fallout in the recent commit d15d662e89fc ("ALSA: seq: Fix racy pool initializations") for CVE-2018-1000004. As the pool resize deletes the existing cells, it may lead to a race when another thread is writing concurrently, eventually resulting a UAF. A simple workaround is not to allow the pool resizing when the pool is in use. It's an invalid behavior in anyway.

2018-03-08ALSA: vmaster: Zero-clear ctl before calling slave getTakashi Iwai
Use kzalloc() instead of kmalloc() so that we don't need to rely fully on the slave get() callback to clear the control value that might be copied to user-space. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2018-03-08ALSA: vmaster: Propagate slave errorTakashi Iwai
In slave_update() of vmaster code ignores the error from the slave get() callback and copies the values. It's not only about the missing error code but also that this may potentially lead to a leak of uninitialized variables when the slave get() don't clear them. This patch fixes slave_update() not to copy the potentially uninitialized values when an error is returned from the slave get() callback, and to propagate the error value properly.

When the BYT_RT5651_MCLK_EN quirk is set, we disable the MCLK from byt_rt5651_init(), we need to select the RCCLK as sysclk before doing this to make sure that jack-detect works directly after boot. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-03-07ASoC: Intel: bytcr_rt5651: Change defaults to enable jack-detect, analog micsHans de Goede
Change the default quirk settings to enable jack-detect, analog mics. The old default input mapping of DMIC for non Bay Trail CR devices seems like a poor default as I'm not aware of any Intel SST + rt5651 using devices with a DMIC. All Cherry Trail devices using the bytcr_rt5651 machine driver seem to be modelled after BYT-CR devices, And the only non CR Bay Trail devices with a rt5651 codec I'm aware of are the Minnow boards for which we already have board specific quirks. So it seems better to me to use the BYT-CR defaults everywhere. This e.g. makes the Chuwi Hi8 Pro (CWI513) work ootb without needing a quirk.

2018-03-07ASoC: Intel: bytcr_rt5651: Add support for Bay Trail CR / SSP0 using boardsHans de Goede
Despite its name being prefixed with bytcr, before this commit the bytcr_rt5651 machine driver could not work with Bay Trail CR boards, as those only have SSP0 and it only supported SSP0-AIF1 setups. This commit adds support for this, autodetecting AIF1 vs AIF2 based on BIOS tables. While at it also add support for SSP2-AIF2 setups, as that requires only minimal extra code on top of the code adding SSP0-AIF1 / SSP0-AIF2 support. Note this code is all copy-pasted from bytcr_rt5640.c. I've looked into merging the 2 machine drivers into 1 to avoid copy-pasting, but there are enough subtile differences to make this hard *and* with all the quirks the machine driver already is full with if (variant-foo) then ... else ... constructs adding more of these is going to make the code unreadable.

Before this commit it was possible to set the DMIC_EN quirk in the machine driver, but it would never be passed to the codec driver so it was a nop. This commit adds code to actually pass the quirk to the codec driver. Since the DMIC_EN quirk was ignored before, this commit removes it from the default quirk settings, to avoid this causing an unexpected functional change.

2018-03-07ASoC: rt5651: Rewrite jack-type detectionHans de Goede

Testing has shown that this short-circuit may happen as late as 500ms after the insertion event, but it never lasts longer then 300ms.

2018-03-07ASoC: rt5651: Allow specifying the OVCD scale-factor through a device-propertyHans de Goede
OVer-Current-Detection (OVCD) for the micbias current is used to detect if an inserted jack is a headset or headphones (mic shorted to ground). The threshold for at which current the OVCD triggers on the rt5651 is not only controlled by setting the absolute current limit, but also by setting a scale factor which applies to the limit. Testing has shown that we need to set both (depending on the board). This commit adds support for the sofar unused OVCD scale-factor register and adds support for specifying non-default values for it through the "realtek,over-current-scale-factor" device-property.

OVer-Current-Detection (OVCD) for the micbias current is used to detect if an inserted jack is a headset or headphones (mic shorted to ground). Some boards may need different values for the OVCD current threshold because of a resistor on the board in serial with or parallel to the jack mic contact. This commit adds support for configuring the OCVD current threshold through the "realtek,over-current-threshold-microamp" device-property.

2018-03-07ASoC: rt5651: Make rt5651_apply_properties() privateHans de Goede
The idea behind exporting rt5651_apply_properties(), was for it to be used on platforms where the platform code may need to add device-properties, rather then relying only on properties set by the firmware. The platform code could then call rt5651_apply_properties() after adding properties to make sure that the codec driver was aware of the new properties. But this is not necessary, as long as we do all property parsing from the codec component-driver's probe function (or later) then the machine driver can attach properties before calling snd_soc_register_card and calling rt5651_apply_properties() for ordering reasons is not necessary. This commit makes rt5651_apply_properties() private and adds 2 comments documenting that all property parsing must be done from the codec component-driver's probe function.

The dock line-out pin (NID 0x17 of ALC3254 codec) on Dell Precision 7520 may route to three different DACs, 0x02, 0x03 and 0x06. The first two DACS have the volume amp controls while the last one doesn't. And unfortunately, the auto-parser assigns this pin to DAC3, resulting in the non-working volume control for the line out.

2018-03-06ALSA: hda/realtek - Add headset mode support for Dell laptopKailang Yang
This platform was only one phone Jack. Add dummy lineout verb to fix automute mode disable. This just the workaround. [ More background information: since the platform has only a headphone jack without speaker, the driver doesn't create the auto-mute control. Meanwhile we do update the headset mode via the automute hook in the driver, thus with this setup, the headset won't be updated any longer. By adding a dummy line-out pin here, the auto-mute is added by the driver, and the headset update is triggered properly. Note that this is different from the other ALC274_FIXUP_DELL_AIO_LINEOUT_VERB, which has the real line-out pin, while this quirk adds a dummy line-out pin. -- tiwai ] Signed-off-by: Kailang Yang <kailang@realtek.com> Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2018-03-01ASoC: rt5651: Enable LDO and micbias1 supplies for jack-type detectionHans de Goede
To determine if a plugged in jack is a headset (speakers + mic) or headphones (mic contact shorted to ground) we use the micbias1 OVer Current Detect (OVCD) functionality. For this to work we need to have a micbias current to actually cause an overcurrent condition when headphones are plugged in, so jack-type detection requires both the LDO and micbias1 supplies to be on. Before this commit there were 2 issues with the handling of this: 1) The LDO supply was force-enabled twice and never disabled again even though it only needs to be forced on when doing jack-type detection 2) micbias1 was not force-enabled, and thus may be off when doing jack-type detection This commit fixes both by force-enabling the LDO and micbias1 supplies before checking for an overcurrent condition and disabling them afterwards. Note that both supplies will still get turned on normally (and OVCD will protect against overcurrent) when the micbias1 is enabled normally because the user has activated a sound stream recording from the mic.

Note there is a separate on/off bit for the LDO. rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, when jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep the LDO voltage at 1.2 volt. This commit removes the jack-detect special case, instead simply always leaving the LDO voltage control bits as is on BIAS_OFF.
