2014-09-25ALSA: hda/realtek - Avoid setting wrong COEF on ALC269 & coTakashi Iwai
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.

2014-06-26ALSA: control: Make sure that id->index does not overflowLars-Peter Clausen
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. This patch adds a check that makes sure that controls with a overflowing index range can not be created.

2014-06-26ALSA: control: Handle numid overflowLars-Peter Clausen
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 Clausen
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 Clausen
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 Keepax
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.

2014-04-14ALSA: hda - hdmi: Fallback to ALSA allocation when selecting CAAnssi Hannula
commit 18e391862cceaf43ddb8eb5cca05e1a83abdebaa upstream. hdmi_channel_allocation() tries to find a HDMI channel allocation that matches the number channels in the playback stream and contains only speakers that the HDMI sink has reported as available via EDID. If no such allocation is found, 0 (stereo audio) is used. Using CA 0 causes the audio causes the sink to discard everything except the first two channels (front left and front right). However, the sink may be capable of receiving more channels than it has speakers (and then perform downmix or discard the extra channels), in which case it is preferable to use a CA that contains extra channels than to use CA 0 which discards all the non-stereo channels. Additionally, it seems that HBR (HD) passthrough output does not work on Intel HDMI codecs when CA is set to 0 (possibly the codec zeroes channels not present in CA). This happens with all receivers that report a 5.1 speaker mask since a HBR stream is carried on 8 channels to the codec. Add a fallback in the CA selection so that the CA channel count at least matches the stream channel count, even if the stream contains channels not present in the sink speaker descriptor. Thanks to GrimGriefer at OpenELEC forums for discovering that changing the sink speaker mask allowed HBR output.

We've seen the broken HDMI *video* output on some machines with GM965, and the debugging session pointed that the culprit is the disabled audio output pins. Toggling these pins dynamically on demand caused flickering of HDMI TV. This patch changes the behavior to keep the pin ON constantly.

2014-04-14Revert "ALSA: hda - Shut up pins at power-saving mode with Conexnat codecs"David Henningsson
commit 7ed4165e2d01bdbbb4c1086eb73eadf0f64cbbf0 upstream. This reverts commit 697c373e34613609cb5450f98b91fefb6e910588. The original patch was meant to remove clicking, but in fact caused even more clicking instead. Thanks to c4pp4 for doing most of the work with this bug.

2014-04-14ALSA: hda - Fix non-snoop page handlingTakashi Iwai
commit 9ddf1aeb2134e72275c97a2c6ff2e3eb04f2f27a upstream. For non-snoop mode, we fiddle with the page attributes of CORB/RIRB and the position buffer, but also the ring buffers. The problem is that the current code blindly assumes that the buffer is contiguous. However, the ring buffers may be SG-buffers, thus a wrong vmapped address is passed there, leading to Oops. This patch fixes the handling for SG-buffers.

commit edac894389f9c9de2a1368c78809c824b343f3a5 upstream. snd-aloop driver has no proper PM implementation, thus the PM resume may trigger Oops due to leftover timer instance. This patch adds the missing suspend/resume implementation.

2014-04-14ALSA: usb: Add quirk for 192KHz recording on E-Mu devicesCalvin Owens
commit 1539d4f82ad534431cc67935e8e442ccf107d17d upstream. When recording at 176.2KHz or 192Khz, the device adds a 32-bit length header to the capture packets, which obviously needs to be ignored for recording to work properly. Userspace expected: L0 L1 L2 R0 R1 R2 ...but actually got: R2 L0 L1 L2 R0 R1 Also, the last byte of the length header being interpreted as L0 of the first sample caused spikes every 0.5ms, resulting in a loud 16KHz tone (about the highest 'B' on a piano) being present throughout captures. Tested at all sample rates on an E-Mu 0404USB, and tested for regressions on a generic USB headset.

2014-03-30ALSA: compress: Pass through return value of open ops callbackCharles Keepax
commit 749d32237bf39e6576dd95bfdf24e4378e51716c upstream. The snd_compr_open function would always return 0 even if the compressed ops open function failed, obviously this is incorrect. Looks like this was introduced by a small typo in: commit a0830dbd4e42b38aefdf3fb61ba5019a1a99ea85 ALSA: Add a reference counter to card instance This patch returns the value from the compressed op as it should.

commit 1f91ecc14deea9461aca93273d78871ec4d98fcd upstream. When selecting the audio output destinations (headphones, FP headphones, multichannel output), the channel routing should be changed depending on what destination selected. Also unnecessary I2S channels are digitally muted. This function called when the user selects the destination in the ALSA mixer.
