[alsa-devel] [PATCH] ALSA: isa/wavefront: Fix potential Spectre v1 vulnerabilities
by Gustavo A. R. Silva 20 Dec '18

20 Dec '18

header->number is indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: sound/isa/wavefront/wavefront_synth.c:792 wavefront_send_patch() warn: potential spectre issue 'dev->patch_status' [w] (local cap) sound/isa/wavefront/wavefront_synth.c:819 wavefront_send_program() warn: potential spectre issue 'dev->prog_status' [w] (local cap) sound/isa/wavefront/wavefront_synth.c:1197 wavefront_send_alias() warn: potential spectre issue 'dev->sample_status' [w] sound/isa/wavefront/wavefront_synth.c:1248 wavefront_send_multisample() warn: potential spectre issue 'dev->sample_status' [w] sound/isa/wavefront/wavefront_synth.c:1548 wavefront_synth_control() warn: potential spectre issue 'dev->sample_status' [r] (local cap) Fix this by sanitizing header->number before using it to index dev->patch_status, dev->prog_status and dev->sample_status. Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

[alsa-devel] [PATCH 0/9] ASoC/ARM: Merge the davinci and omap audio directories
by Peter Ujfalusi 20 Dec '18

20 Dec '18

Hi, Changes since RFC: - Added Jarkko's Acked-by/Tested-by for the {omap->ti} changes - Rebased on top of next-20181210 (20181214+ is not booting on any of my boards) For Texas Instruments audio support we have two directories at the moment: davinci omap In reality TI have the following SoC lines supported by Linux: daVinci OMAP Sitara Keystone We already needed to have cross directory 'links' for DRA7x/AM5 since they use McASP (davinci directory) and sDMA (omap directory). Keystone II line of SoCs are using drivers from davinci directory (McASP and EDMA). Which is kind of fine as they are in the same place. With the new AM654 (http://www.ti.com/lit/pdf/spruid7) we will have completely new DMA and there is no place to put that as it does not belong under davinci or omap, but it makes no sense to create yet another TI related directory just for the small udma-pcm. Another issue with the current support is how the Kconfigs are written. The DAI drivers are depending on the ASoC platform drivers and it is a bit of a mess at the moment. For simple-sound-card one need to know what DMA is used and then select the DAI driver (if the Kconfig is right). I have also cleaned up the Kconfig prompts and comments a bit to be more precise. As can be seen in the diffstat I tried to do the merger with minimal code change, resisting the urge to rename the davinci-i2c driver to davinci-asp. With the merger I have created a new Kconfig structure: - Submenu for TI related settings for clarity - Only the DAI drivers are selectable and the platform drivers are selected based on the available (enabled) DMA engines - The remaining ASoC machine drivers are selecting the DAIs they need - The davinci-evm is now a single entry, combining all the various daVinci EVMS it supports and selects the needed DAIs based on the enabled boards The series also includes patches to updated the arch/arm/ files (defconfigs, source files using audio Kconfig symbols). I think I have catched all (I hope) issues regarding to Kconfig thanks to the various autobuild machines out there kindly testing my linux-next-wip branch. Mark, Tony, Sekhar: This series - as I mentioned - is based on next-20181210. Not sure what tag, branch, commit I should base this, but I can resend v2 if needed.

[alsa-devel] alsa-lib: commit ce2095c41f2891c51f5dbd28e0317200314c5a75 breaks speaker-test/pulseaudio
by Diego Viola 19 Dec '18

19 Dec '18

Hello Takashi, I currently have an issue with speaker-test and pulseaudio, and the root of the problem seems to be a regression in alsa-lib. The issue occurs when I run speaker-test, it creates endless output with no sound, and the output does not stop until I hit ctrl-c. I've been investigating about this issue and concluded (through a git bisect) that this is a regression in alsa-lib, and this is the bad commit that introduces the bug: commit ce2095c41f2891c51f5dbd28e0317200314c5a75 Author: Takashi Iwai <tiwai(a)suse.de> Date: Thu Mar 29 09:51:46 2018 +0200 pcm: ioplug: Implement proper drain behavior This patch fixes the draining behavior of ioplug in the following ways: - When no draining ioplug callback is defined, implement the draining loop using snd_pcm_wait*() and sync with the drain finishes. This is equivalent with the implementation in the kernel write(). Similarly as in kernel code, for non-blocking mode, it returns immediately after setting DRAINING state. - The hw_ptr update function checks the PCM state and stops the stream if the draining finishes. - When draining ioplug callback is defined, leave the whole draining operation to it. The callback is supposed to return -EAGAIN for non-blocking case, too. - When an error happens during draining, it drops the stream, for a safety reason. Signed-off-by: Takashi Iwai <tiwai(a)suse.de> I've sanity checked and can confirm that going back to the previous commit fixes the issue. My original bug report on the pulseaudio bug tracker: https://gitlab.freedesktop.org/pulseaudio/pulseaudio/issues/593 Thanks, and please let me know if you need more information. Regards, Diego

[alsa-devel] [PATCH] ASoC: Intel: Haswell/Broadwell: fix setting for .dynamic field
by Rander Wang 19 Dec '18

19 Dec '18

For some reason this field was set to zero when all other drivers use .dynamic = 1 for front-ends. This change was tested on Dell XPS13 and has no impact with the existing legacy driver. The SOF driver also works with this change which enables it to override the fixed topology.

[alsa-devel] Loading coefficients for Audio IP
by Daniel Baluta 19 Dec '18

19 Dec '18

Hello Pierre, Liam, Mark, What is the standard ALSA way of loading tables of coefficients for various audio IPs? We have IPs like PDM or ASRC which need large table of coefficients depending on configuration. This tables can reach up to 120K in size. Creating this kind of tables as arrays of integers in kernel doesn't seem to be a common used solution and we will end up with large files that contains only numbers. Another approach that we are thinking of is to create and compile this tables in userspace as raw binary files and then loading them in kernel using the firmware interface. Would this be an acceptable approach? thanks, Daniel.
