2020-07-07ALSA: usb-audio: Add vendor, product and profile name for HP Thunderbolt DockKai-Heng Feng
commit 0c5086f5699906ec8e31ea6509239489f060f2dc upstream. The HP Thunderbolt Dock has two separate USB devices, one is for speaker and one is for headset. Add names for them so userspace can apply UCM settings.

2020-07-07ALSA: usb-audio: Fix inconsistent card PM state after resumeTakashi Iwai
commit 862b2509d157c629dd26d7ac6c6cdbf043d332eb upstream. When a USB-audio interface gets runtime-suspended via auto-pm feature, the driver suspends all functionality and increment chip->num_suspended_intf. Later on, when the system gets suspended to S3, the driver increments chip->num_suspended_intf again, skips the device changes, and sets the card power state to SNDRV_CTL_POWER_D3hot. In return, when the system gets resumed from S3, the resume callback decrements chip->num_suspended_intf. Since this refcount is still not zero (it's been runtime-suspended), the whole resume is skipped. But there is a small pitfall here. The problem is that the driver doesn't restore the card power state after this resume call, leaving it as SNDRV_CTL_POWER_D3hot. So, even after the system resume finishes, the card instance still appears as if it were system-suspended, and this confuses many ioctl accesses that are blocked unexpectedly. In details, we have two issues behind the scene: one is that the card power state is changed only when the refcount becomes zero, and another is that the prior auto-suspend check is kept in a boolean flag. Although the latter problem is almost negligible since the auto-pm feature is imposed only on the primary interface, but this can be a potential problem on the devices with multiple interfaces. This patch addresses those issues by the following: - Replace chip->autosuspended boolean flag with chip->system_suspend counter - At the first system-suspend, chip->num_suspended_intf is recorded to chip->system_suspend - At system-resume, the card power state is restored when the chip->num_suspended_intf refcount reaches to chip->system_suspend, i.e. the state returns to the auto-suspended Also, the patch fixes yet another hidden problem by the code refactoring along with the fixes above: namely, when some resume procedure failed, the driver left chip->num_suspended_intf that was already decreased, and it might lead to the refcount unbalance. In the new code, the refcount decrement is done after the whole resume procedure, and the problem is avoided as well.

2020-06-24ASoC: core: only convert non DPCM link to DPCM linkBard Liao
commit 607fa205a7e4dfad28b8a67ab1c985756ddbccb0 upstream. Additional checks for valid DAIs expose a corner case, where existing BE dailinks get modified, e.g. HDMI links are tagged with dpcm_capture=1 even if the DAIs are for playback. This patch makes those changes conditional and flags configuration issues when a BE dailink is has no_pcm=0 but dpcm_playback or dpcm_capture=1 (which makes no sense). As discussed on the alsa-devel mailing list, there are redundant flags for dpcm_playback, dpcm_capture, playback_only, capture_only. This will have to be cleaned-up in a future update. For now only correct and flag problematic configurations.

2020-06-08ALSA: usb-audio: Quirks for Gigabyte TRX40 Aorus Master onboard audioTakashi Iwai
commit 7f5ad9c9003425175f46c94df380e8c9e558cfb5 upstream. Gigabyte TRX40 Aorus Master is equipped with two USB-audio devices, a Realtek ALC1220-VB codec (USB ID 0414:a001) and an ESS SABRE9218 DAC (USB ID 0414:a000). The latter serves solely for the headphone output on the front panel while the former serves for the rest I/Os (mostly for the I/Os in the rear panel but also including the front mic). Both chips do work more or less with the unmodified USB-audio driver, but there are a few glitches. The ALC1220-VB returns an error for an inquiry to some jacks, as already seen on other TRX40-based mobos. However this machine has a slightly incompatible configuration, hence the existing mapping cannot be used as is. Meanwhile the ESS chip seems working without any quirk. But since both audio devices don't provide any specific names, both cards appear as "USB-Audio", and it's quite confusing for users. This patch is an attempt to overcome those issues: - The specific mapping table for ALC1220-VB is provided, reducing the non-working nodes and renaming the badly chosen controls. The connector map isn't needed here unlike other TRX40 quirks. - For both USB IDs (0414:a000 and 0414:a001), provide specific card name strings, so that user-space can identify more easily; and more importantly, UCM profile can be applied to each.

2020-06-08ALSA: hda/realtek - Add a model for Thinkpad T570 without DAC workaroundTakashi Iwai
commit 399c01aa49e548c82d40f8161915a5941dd3c60e upstream. We fixed the regression of the speaker volume for some Thinkpad models (e.g. T570) by the commit 54947cd64c1b ("ALSA: hda/realtek - Fix speaker output regression on Thinkpad T570"). Essentially it fixes the DAC / pin pairing by a static table. It was confirmed and merged to stable kernel later. Now, interestingly, we got another regression report for the very same model (T570) about the similar problem, and the commit above was the culprit. That is, by some reason, there are devices that prefer the DAC1, and another device DAC2! Unfortunately those have the same ID and we have no idea what can differentiate, in this patch, a new fixup model "tpt470-dock-fix" is provided, so that users with such a machine can apply it manually. When model=tpt470-dock-fix option is passed to snd-hda-intel module, it avoids the fixed DAC pairing and the DAC1 is assigned to the speaker like the earlier versions.

2020-06-08ALSA: pcm: fix incorrect hw_base increaseBrent Lu
commit e7513c5786f8b33f0c107b3759e433bc6cbb2efa upstream. There is a corner case that ALSA keeps increasing the hw_ptr but DMA already stop working/updating the position for a long time. In following log we can see the position returned from DMA driver does not move at all but the hw_ptr got increased at some point of time so snd_pcm_avail() will return a large number which seems to be a buffer underrun event from user space program point of view. The program thinks there is space in the buffer and fill more data.

As the hw_base increases, so does the hw_ptr increased by the same number. The avail value returned from snd_pcm_avail() could exceed the limit (buffer_size) easily becase the hw_ptr itself got increased by same buffer_size samples when the corner case happens. In following log, the buffer_size is 16368 samples but the avail is 21810 samples so CRAS server complains about it.

2020-06-08ALSA: hda: Manage concurrent reg access more properlyTakashi Iwai
commit 1a462be52f4505a2719631fb5aa7bfdbd37bfd8d upstream. In the commit 8e85def5723e ("ALSA: hda: enable regmap internal locking"), we re-enabled the regmap lock due to the reported regression that showed the possible concurrent accesses. It was a temporary workaround, and there are still a few opened races even after the revert. In this patch, we cover those still opened windows with a proper mutex lock and disable the regmap internal lock again. First off, the patch introduces a new snd_hdac_device.regmap_lock mutex that is applied for each snd_hdac_regmap_*() call, including read, write and update helpers. The mutex is applied carefully so that it won't block the self-power-up procedure in the helper function. Also, this assures the protection for the accesses without regmap, too. The snd_hdac_regmap_update_raw() is refactored to use the standard regmap_update_bits_check() function instead of the open-code. The non-regmap case is still open-coded but it's an easy part. The all read and write operations are in the single mutex protection, so it's now race-free. In addition, a couple of new helper functions are added: snd_hdac_regmap_update_raw_once() and snd_hdac_regmap_sync(). Both are called from HD-audio legacy driver. The former is to initialize the given verb bits but only once when it's not initialized yet. Due to this condition, the function invokes regcache_cache_only(), and it's now performed inside the regmap_lock (formerly it was racy) too. The latter function is for simply invoking regcache_sync() inside the regmap_lock, which is called from the codec resume call path. Along with that, the HD-audio codec driver code is slightly modified / simplified to adapt those new functions. And finally, snd_hdac_regmap_read_raw(), *_write_raw(), etc are rewritten with the helper macro. It's just for simplification because the code logic is identical among all those functions.

2020-06-08ALSA: rawmidi: Fix racy buffer resize under concurrent accessesTakashi Iwai
commit c1f6e3c818dd734c30f6a7eeebf232ba2cf3181d upstream. The rawmidi core allows user to resize the runtime buffer via ioctl, and this may lead to UAF when performed during concurrent reads or writes: the read/write functions unlock the runtime lock temporarily during copying form/to user-space, and that's the race window. This patch fixes the hole by introducing a reference counter for the runtime buffer read/write access and returns -EBUSY error when the resize is performed concurrently against read/write. Note that the ref count field is a simple integer instead of refcount_t here, since the all contexts accessing the buffer is basically protected with a spinlock, hence we need no expensive atomic ops. Also, note that this busy check is needed only against read / write functions, and not in receive/transmit callbacks; the race can happen only at the spinlock hole mentioned in the above, while the whole function is protected for receive / transmit callbacks.

2020-06-08ALSA: hda/hdmi: fix race in monitor detection during probeKai Vehmanen
commit ca76282b6faffc83601c25bd2a95f635c03503ef upstream. A race exists between build_pcms() and build_controls() phases of codec setup. Build_pcms() sets up notifier for jack events. If a monitor event is received before build_controls() is run, the initial jack state is lost and never reported via mixer controls. The problem can be hit at least with SOF as the controller driver. SOF calls snd_hda_codec_build_controls() in its workqueue-based probe and this can be delayed enough to hit the race condition. Fix the issue by invalidating the per-pin ELD information when build_controls() is called. The existing call to hdmi_present_sense() will update the ELD contents. This ensures initial monitor state is correctly reflected via mixer controls.

The commit 3c6fd1f07ed0 ("ALSA: hda: Add driver blacklist") added a new blacklist for the devices that are known to have empty codecs, and one of the entries was ASUS ROG Zenith II (PCI SSID 1043:874f). However, it turned out that the very same PCI SSID is used for the previous model that does have the valid HD-audio codecs and the change broke the sound on it. Since the empty codec problem appear on the certain AMD platform (PCI ID 1022:1487), this patch changes the blacklist matching to both PCI ID and SSID using pci_match_id(). Also, the entry that was removed by the previous fix for ASUS ROG Zenigh II is re-added.

2020-06-04ASoC: rsnd: Don't treat master SSI in multi SSI setup as parentMatthias Blankertz
commit 0c258657ddfe81b4fc0183378d800c97ba0b7cdd upstream. The master SSI of a multi-SSI setup was attached both to the RSND_MOD_SSI slot and the RSND_MOD_SSIP slot of the rsnd_dai_stream. This is not correct wrt. the meaning of being "parent" in the rest of the SSI code, where it seems to indicate an SSI that provides clock and word sync but is not transmitting/receiving audio data. Not treating the multi-SSI master as parent allows removal of various special cases to the rsnd_ssi_is_parent conditions introduced in commit a09fb3f28a60 ("ASoC: rsnd: Fix parent SSI start/stop in multi-SSI mode"). It also fixes the issue that operations performed via rsnd_dai_call() were performed twice for the master SSI. This caused some "status check failed" spam when stopping a multi-SSI stream as the driver attempted to stop the master SSI twice.

commit b94e164759b82d0c1c80d4b1c8f12c9bee83f11d upstream. The HDMI?_SEL register maps up to four stereo SSI data lanes onto the sdata[0..3] inputs of the HDMI output block. The upper half of the register contains four blocks of 4 bits, with the most significant controlling the sdata3 line and the least significant the sdata0 line. The shift calculation has an off-by-one error, causing the parent SSI to be mapped to sdata3, the first multi-SSI child to sdata0 and so forth. As the parent SSI transmits the stereo L/R channels, and the HDMI core expects it on the sdata0 line, this causes no audio to be output when playing stereo audio on a multichannel capable HDMI out, and multichannel audio has permutated channels.

commit 482db55ae87f3749db05810a38b1d618dfd4407c upstream. Function soc_tplg_create_tlv can fail, so we should check if it succeded or not and proceed appropriately.

2020-06-04ALSA: opti9xx: shut up gcc-10 range warningArnd Bergmann
commit 5ce00760a84848d008554c693ceb6286f4d9c509 upstream. gcc-10 points out a few instances of suspicious integer arithmetic leading to value truncation: sound/isa/opti9xx/opti92x-ad1848.c: In function 'snd_opti9xx_configure': sound/isa/opti9xx/opti92x-ad1848.c:322:43: error: overflow in conversion from 'int' to 'unsigned char' changes value from '(int)snd_opti9xx_read(chip, 3) & -256 | 240' to '240' [-Werror=overflow] 322 | (snd_opti9xx_read(chip, reg) & ~(mask)) | ((value) & (mask))) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ sound/isa/opti9xx/opti92x-ad1848.c:351:3: note: in expansion of macro 'snd_opti9xx_write_mask' 351 | snd_opti9xx_write_mask(chip, OPTi9XX_MC_REG(3), 0xf0, 0xff); | ^~~~~~~~~~~~~~~~~~~~~~ sound/isa/opti9xx/miro.c: In function 'snd_miro_configure': sound/isa/opti9xx/miro.c:873:40: error: overflow in conversion from 'int' to 'unsigned char' changes value from '(int)snd_miro_read(chip, 3) & -256 | 240' to '240' [-Werror=overflow] 873 | (snd_miro_read(chip, reg) & ~(mask)) | ((value) & (mask))) | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ sound/isa/opti9xx/miro.c:1010:3: note: in expansion of macro 'snd_miro_write_mask' 1010 | snd_miro_write_mask(chip, OPTi9XX_MC_REG(3), 0xf0, 0xff); | ^~~~~~~~~~~~~~~~~~~ These are all harmless here as only the low 8 bit are passed down anyway. Change the macros to inline functions to make the code more readable and also avoid the warning. Strictly speaking those functions also need locking to make the read/write pair atomic, but it seems unlikely that anyone would still run into that issue.
