* ALSA: seq: Fix races at MIDI encoding in snd_virmidi_output_trigger()Takashi Iwai2018-04-271-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The sequencer virmidi code has an open race at its output trigger callback: namely, virmidi keeps only one event packet for processing while it doesn't protect for concurrent output trigger calls. snd_virmidi_output_trigger() tries to process the previously unfinished event before starting encoding the given MIDI stream, but this is done without any lock. Meanwhile, if another rawmidi stream starts the output trigger, this proceeds further, and overwrites the event package that is being processed in another thread. This eventually corrupts and may lead to the invalid memory access if the event type is like SYSEX. The fix is just to move the spinlock to cover both the pending event and the new stream. The bug was spotted by a new fuzzer, RaceFuzzer.

| | | | | | | | | | | The commit c469652bb5e8 ("ALSA: hda - Use IS_REACHABLE() for dependency on input") simplified the dependencies with IS_REACHABLE() macro, but it broke due to its incorrect usage: it should have been IS_REACHABLE(CONFIG_INPUT) instead of IS_REACHABLE(INPUT).

* ALSA: hda - Skip jack and others for non-existing PCM streamsTakashi Iwai2018-04-251-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited number of devices available, and HD-audio, especially with HDMI/DP codec, will fail to create more than two devices. The driver warns about the lack of such devices and skips the PCM device creations, but the HDMI driver still tries to create the corresponding JACK, SPDIF and ELD controls even for the non-existing PCM substreams. This results in confusion on user-space, and even may break the operation. Similarly, Intel HDMI/DP codec builds the ELD notification from i915 graphics driver, and this may be broken if a notification is sent for the non-existing PCM stream. This patch adds the check of the existence of the assigned PCM substream in the both scenarios above, and skips the further operation if the PCM substream is not assigned.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a partial revert (in a cleaner way) of commit ebf08ae3bc90 ("ASoC: fsl_ssi: Keep ssi->i2s_net updated") to fix a regression at test cases when switching between mono and stereo audio. The problem is that ssi->i2s_net is initialized in set_dai_fmt() only, while this set_dai_fmt() is only called during the dai-link probe(). The original patch assumed set_dai_fmt() would be called during every playback instance, so it failed at the overriding use cases. This patch adds the local variable i2s_net back to let regular use cases still follow the mode settings from the set_dai_fmt(). Meanwhile, the original commit of keeping ssi->i2s_net updated was to make set_tdm_slot() clean by checking the ssi->i2s_net directly instead of reading SCR register. However, the change itself is not necessary (or even harmful) because the set_tdm_slot() might fail to check the slot number for Normal-Mode-None-Net settings while mono audio cases still need 2 slots. So this patch can also fix it. And it adds an extra line of comments to declare ssi->i2s_net does not reflect the register value but merely the initial setting from the set_dai_fmt().

| * ASoC: fsl_esai: Fix divisor calculation failure at lower ratioNicolin Chen2018-04-121-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the desired ratio is less than 256, the savesub (tolerance) in the calculation would become 0. This will then fail the loop- search immediately without reporting any errors. But if the ratio is smaller enough, there is no need to calculate the tolerance because PM divisor alone is enough to get the ratio. So a simple fix could be just to set PM directly instead of going into the loop-search.

* | ALSA: usb-audio: Fix missing endian conversionTakashi Iwai2018-04-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | The UAC2 jack detection support introduced the bmControls checks in a couple of places, but they forgot the endian conversion; the bmControls of UAC2 terminal descriptor is __le16, not a byte like in UAC1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The recent code refactoring made the argument for some helper functions to be the explicit UAC_CS_* and UAC2_CS_* value instead of 0-based offset. However, there was one place left forgotten, and it caused a regression on some devices appearing as the inconsistent mixer setup. This patch corrects the forgotten conversion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It looks like a simple mistake that this struct member was forgotten. Audio_tstamp isn't used much, and on some archs (such as x86) this ioctl is not used by default, so that might be the reason why this has slipped for so long.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit c2c86a97175f ("ALSA: pcm: Remove set_fs() in PCM core code") changed SNDRV_PCM_IOCTL_DELAY to return an inconsistent error instead of a negative delay. Originally the call would succeed and return the negative delay. The Chromium OS Audio Server (CRAS) gets confused and hangs when the error is returned instead of the negative delay. Help CRAS avoid the issue by rolling back the behavior to return a negative delay instead of an error.
