ALSA: hda - Handle kzalloc() failure in snd_hda_attach_pcm_stream()

2018-06-25T23:53:59+00:00

commit a3aa60d511746bd6c0d0366d4eb90a7998bcde8b upstream. When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is created without setting its operators via 'snd_pcm_set_ops()'. Following operations on the new pcm instance can trigger kernel null pointer dereferences and cause kernel oops. This bug was found with my work on building a gray-box fault-injection tool for linux-kernel-module binaries. A kernel null pointer dereference was confirmed from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in file 'sound/core/pcm_native.c'. This patch fixes the bug by calling 'snd_device_free()' in the error handling path of 'kzalloc()', which removes the new pcm instance from the snd card before returns with an error code.

ALSA: hda/conexant - Add fixup for HP Z2 G4 workstation

2018-06-25T23:53:59+00:00

commit f16041df4c360eccacfe90f96673b37829e4c959 upstream. HP Z2 G4 requires the same workaround as other HP machines that have no mic-pin detection. Cc: Signed-off-by: Takashi Iwai Signed-off-by: Greg Kroah-Hartman

ALSA: hda/realtek - Enable mic-mute hotkey for several Lenovo AIOs

2018-06-25T23:53:58+00:00

commit 986376b68dcc95bb7df60ad30c2353c1f7578fa5 upstream. We have several Lenovo AIOs like M810z, M820z and M920z, they have the same design for mic-mute hotkey and led and they use the same codec with the same pin configuration, so use the pin conf table to apply fix to all of them.

ALSA: usb-audio: Disable the quirk for Nura headset

2018-06-25T23:53:58+00:00

commit 5ebf6b1e459606d7fbf4fc67d2c28a6540953d93 upstream. The commit 33193dca671c ("ALSA: usb-audio: Add a quirk for Nura's first gen headset") added a quirk for Nura headset with USB ID 0a12:1243, with a hope that it doesn't conflict with others. Unfortunately, other devices (e.g. Philips Wecall) with the very same ID got broken by this change, spewing an error like: usb 2-1.8.2: 2:1: cannot set freq 48000 to ep 0x3 Until we find a proper solution, fix the regression at first by disabling the added quirk entry.
