* ALSA: pcm: Fix rwsem deadlock for non-atomic PCM streamTakashi Iwai2016-02-181-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | A non-atomic PCM stream may take snd_pcm_link_rwsem rw semaphore twice in the same code path, e.g. one in snd_pcm_action_nonatomic() and another in snd_pcm_stream_lock(). Usually this is OK, but when a write lock is issued between these two read locks, the problem happens: the write lock is blocked due to the first reade lock, and the second read lock is also blocked by the write lock. This eventually deadlocks. The reason is the way rwsem manages waiters; it's queued like FIFO, so even if the writer itself doesn't take the lock yet, it blocks all the waiters (including reads) queued after it. As a workaround, in this patch, we replace the standard down_write() with an spinning loop. This is far from optimal, but it's good enough, as the spinning time is supposed to be relatively short for normal PCM operations, and the code paths requiring the write lock aren't called so often.

* ALSA: seq: Fix double port list deletionTakashi Iwai2016-02-161-5/+8
| | | | | | | | | | | | | | | | | | | The commit [7f0973e973cd: ALSA: seq: Fix lockdep warnings due to double mutex locks] split the management of two linked lists (source and destination) into two individual calls for avoiding the AB/BA deadlock. However, this may leave the possible double deletion of one of two lists when the counterpart is being deleted concurrently. It ends up with a list corruption, as revealed by syzkaller fuzzer. This patch fixes it by checking the list emptiness and skipping the deletion and the following process.

* ALSA: hda - Cancel probe work instead of flush at removeTakashi Iwai2016-02-151-2/+2
| | | | | | | | | | | | | | | The commit [991f86d7ae4e: ALSA: hda - Flush the pending probe work at remove] introduced the sync of async probe work at remove for fixing the race. However, this may lead to another hangup when the module removal is performed quickly before starting the probe work, because it issues flush_work() and it's blocked forever. The workaround is to use cancel_work_sync() instead of flush_work() there.

* ALSA: seq: Fix leak of pool buffer at concurrent writesTakashi Iwai2016-02-151-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | When multiple concurrent writes happen on the ALSA sequencer device right after the open, it may try to allocate vmalloc buffer for each write and leak some of them. It's because the presence check and the assignment of the buffer is done outside the spinlock for the pool. The fix is to move the check and the assignment into the spinlock. (The current implementation is suboptimal, as there can be multiple unnecessary vmallocs because the allocation is done before the check in the spinlock. But the pool size is already checked beforehand, so this isn't a big problem; that is, the only possible path is the multiple writes before any pool assignment, and practically seen, the current coverage should be "good enough".) The issue was triggered by syzkaller fuzzer.

In v4.4 kernel dma_ops would end up pointing to dummy_dma_ops in such cases. So attempting to use such device in allocating coherent memory on aarch64 would fail. According to commit 1dccb598df549d892b6450c261da54cdd7af44b4 ("arm64: simplify dma_get_ops") The current behavior of dma_get_ops is to fall back to the global dma_ops when a device has not set its own dma_ops, but only for DT based systems.

But Atom-DPCM driver does not use common sst code so we cannot include the common SST module in Atom-DPCM driver. So the solution is to have a independent sst-match-acpi module which helps in matching for all the three drivers. Now all driver can be inbuilt in a single image This patch really fixes the regression introduced by the commit 95f098014815 ("ASoC: Intel: Move apci find machine routines") Acked-by: Jie Yang <yang.jie@intel.com> Acked-by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>

So two new functions are added for checking and current functions are re-purposed to only add the resources for memory and MCPS.

The net result was a regression at probe on all Atom platforms with no sound card created. Fix by adding explicit initialization for channel_min to 1 for the compress-cpu-dai.
