ALSA: hda - fix a problem for lineout on a Dell AIO machine

2017-04-08T07:53:31+00:00

commit 2f726aec19a9d2c63bec9a8a53a3910ffdcd09f8 upstream.

On this Dell AIO machine, the lineout jack does not work.

We found the pin 0x1a is assigned to lineout on this machine, and in
the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
heaset-set mic problem for this machine, this fixup will redefine
the pin 0x1a to headphone-mic, as a result the lineout doesn't
work anymore.

After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.

[rearranged the fixup insertion position by tiwai in order to make the
 merge with other branches easier -- tiwai]

ALSA: seq: Fix race during FIFO resize

2017-04-08T07:53:31+00:00

commit 2d7d54002e396c180db0c800c1046f0a3c471597 upstream.

When a new event is queued while processing to resize the FIFO in
snd_seq_fifo_clear(), it may lead to a use-after-free, as the old pool
that is being queued gets removed.  For avoiding this race, we need to
close the pool to be deleted and sync its usage before actually
deleting it.

The issue was spotted by syzkaller.

ALSA: hda - Adding a group of pin definition to fix headset problem

2017-03-30T07:35:16+00:00

commit 3f307834e695f59dac4337a40316bdecfb9d0508 upstream.

A new Dell laptop needs to apply ALC269_FIXUP_DELL1_MIC_NO_PRESENCE to
fix the headset problem, and the pin definiton of this machine is not
in the pin quirk table yet, now adding it to the table.

ALSA: ctxfi: Fix the incorrect check of dma_set_mask() call

2017-03-30T07:35:15+00:00

commit f363a06642f28caaa78cb6446bbad90c73fe183c upstream.

In the commit [15c75b09f8d1: ALSA: ctxfi: Fallback DMA mask to 32bit],
I forgot to put "!" at dam_set_mask() call check in cthw20k1.c (while
cthw20k2.c is OK).  This patch fixes that obvious bug.

(As a side note: although the original commit was completely wrong,
 it's still working for most of machines, as it sets to 32bit DMA mask
 in the end.  So the bug severity is low.)

ALSA: seq: Fix racy cell insertions during snd_seq_pool_done()

2017-03-30T07:35:15+00:00

commit c520ff3d03f0b5db7146d9beed6373ad5d2a5e0e upstream.

When snd_seq_pool_done() is called, it marks the closing flag to
refuse the further cell insertions.  But snd_seq_pool_done() itself
doesn't clear the cells but just waits until all cells are cleared by
the caller side.  That is, it's racy, and this leads to the endless
stall as syzkaller spotted.

This patch addresses the racy by splitting the setup of pool->closing
flag out of snd_seq_pool_done(), and calling it properly before
snd_seq_pool_done().

ALSA: hda - Fix micmute hotkey problem for a lenovo AIO machine

2017-03-12T05:37:25+00:00

commit 29693efcea0f38cf40d0055d2401490a4f9bf8be upstream.

On this machine, the micmute button is connected to Line2 of the
codec and the micmute led is connected to GPIO2 of the codec.

After applying this quirk, both hotkey and led work well.

ALSA: seq: Fix link corruption by event error handling

2017-03-12T05:37:25+00:00

commit f3ac9f737603da80c2da3e84b89e74429836bb6d upstream.

The sequencer FIFO management has a bug that may lead to a corruption
(shortage) of the cell linked list.  When a sequencer client faces an
error at the event delivery, it tries to put back the dequeued cell.
When the first queue was put back, this forgot the tail pointer
tracking, and the link will be screwed up.

Although there is no memory corruption, the sequencer client may stall
forever at exit while flushing the pending FIFO cells in
snd_seq_pool_done(), as spotted by syzkaller.

This patch addresses the missing tail pointer tracking at
snd_seq_fifo_cell_putback().  Also the patch makes sure to clear the
cell->enxt pointer at snd_seq_fifo_event_in() for avoiding a similar
mess-up of the FIFO linked list.

ALSA: ctxfi: Fallback DMA mask to 32bit

2017-03-12T05:37:25+00:00

commit 15c75b09f8d190f89ab4db463b87d411ca349dfe upstream.

Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit
architectures, and bails out if it fails.  This causes a problem on
some platforms since the 64bit DMA isn't always guaranteed.  We should
fall back to the default 32bit DMA when 64bit DMA fails.
