2017-08-18ALSA: emu10k1: Fix forgotten user-copy conversion in init codeTakashi Iwai
The commit d42fe63d5839 ("ALSA: emu10k1: Get rid of set_fs() usage") converted the user-space copy hack with set_fs() to the direct memcpy(), but one place was forgotten. This resulted in the error from snd_emu10k1_init_efx(), eventually failed to load the driver. Fix the missing piece.

2017-08-17ALSA: usb-audio: Add mute TLV for playback volumes on C-Media devicesTakashi Iwai
C-Media devices (at least some models) mute the playback stream when volumes are set to the minimum value. But this isn't informed via TLV and the user-space, typically PulseAudio, gets confused as if it's still played in a low volume. This patch adds the new flag, min_mute, to struct usb_mixer_elem_info for indicating that the mixer element is with the minimum-mute volume. This flag is set for known C-Media devices in snd_usb_mixer_fu_apply_quirk() in turn.

2017-08-15ALSA: seq: 2nd attempt at fixing race creating a queueDaniel Mentz
commit 4842e98f26dd80be3623c4714a244ba52ea096a8 ("ALSA: seq: Fix race at creating a queue") attempted to fix a race reported by syzkaller. That fix has been described as follows: " When a sequencer queue is created in snd_seq_queue_alloc(),it adds the new queue element to the public list before referencing it. Thus the queue might be deleted before the call of snd_seq_queue_use(), and it results in the use-after-free error, as spotted by syzkaller. The fix is to reference the queue object at the right time. " Even with that fix in place, syzkaller reported a use-after-free error. It specifically pointed to the last instruction "return q->queue" in snd_seq_queue_alloc(). The pointer q is being used after kfree() has been called on it. It turned out that there is still a small window where a race can happen. The window opens at snd_seq_ioctl_create_queue()->snd_seq_queue_alloc()->queue_list_add() and closes at snd_seq_ioctl_create_queue()->queueptr()->snd_use_lock_use(). Between these two calls, a different thread could delete the queue and possibly re-create a different queue in the same location in queue_list. This change prevents this situation by calling snd_use_lock_use() from snd_seq_queue_alloc() prior to calling queue_list_add(). It is then the caller's responsibility to call snd_use_lock_free(&q->use_lock).

2017-08-11ALSA: seq: Fix CONFIG_SND_SEQ_MIDI dependencyTakashi Iwai
The commit 0181307abc1d ("ALSA: seq: Reorganize kconfig and build") rewrote the dependency of each sequencer module in a standard way, but there was one change applied mistakenly: CONFIG_SND_SEQ_MIDI isn't enabled properly by CONFIG_SND_RAWMIDI. I seem to have changed the wrong one instead, CONFIG_SND_SEQ_MIDI_EMUL, which is eventually reverse-selected by CONFIG_SND_SEQ_MIDI itself. This ended up the lack of snd-seq-midi module as reported below. The fix is to put def_tristate properly to CONFIG_SND_SEQ_MIDI instead of *_MIDI_EMUL entry.

2017-08-01device property: Fix usecount for of_graph_get_port_parent()Tony Lindgren
Fix inconsistent use of of_graph_get_port_parent() where asoc_simple_card_parse_graph_dai() does of_node_get() before calling it while other callers do not. We can fix this by not trashing the node passed to of_graph_get_port_parent(). Let's also make sure the callers have correct refcounts and remove related incorrect of_node_put() calls for of_for_each_phandle as that's done by of_phandle_iterator_next() except when we break out of the loop early. Let's fix both issues with a single patch to avoid kobject refcounts getting messed up more if two patches are merged separately. Otherwise strange issues can happen caused by memory corruption caused by too many kobject_del() calls such as: BUG: sleeping function called from invalid context at kernel/locking/mutex.c:747 ...

2017-07-28NFSv4.1: Fix a race where CB_NOTIFY_LOCK fails to wake a waiterBenjamin Coddington
nfs4_retry_setlk() sets the task's state to TASK_INTERRUPTIBLE within the same region protected by the wait_queue's lock after checking for a notification from CB_NOTIFY_LOCK callback. However, after releasing that lock, a wakeup for that task may race in before the call to freezable_schedule_timeout_interruptible() and set TASK_WAKING, then freezable_schedule_timeout_interruptible() will set the state back to TASK_INTERRUPTIBLE before the task will sleep. The result is that the task will sleep for the entire duration of the timeout. Since we've already set TASK_INTERRUPTIBLE in the locked section, just use freezable_schedule_timout() instead.

2017-07-28lightnvm: pblk: advance bio according to lba indexJavier González
When a lba either hits the cache or corresponds to an empty entry in the L2P table, we need to advance the bio according to the position in which the lba is located. Otherwise, we will copy data in the wrong page, thus causing data corruption for the application. In case of a cache hit, we assumed that bio->bi_iter.bi_idx would contain the correct index, but this is no necessarily true. Instead, use the local bio advance counter and iterator. This guarantees that lbas hitting the cache are copied into the right bv_page. In case of an empty L2P entry, we omitted to advance the bio. In the cases when the same I/O also contains a cache hit, data corresponding to this lba will be copied to the wrong bv_page. Fix this by advancing the bio as we do in the case of a cache hit.

2017-07-28ASoC: Intel: Enabling ASRC for RT5663 codec on kabylake platformHarsha Priya N
This patch fixes the cracking noise in rt5663 headphones for kabylake platform by calling rt5663_sel_asrc_clk_src() for RT5663_AD_STEREO_FILTER to set ASRC. The ASRC function is for asynchronous MCLK and LRCK. For RT5663 ASRC should be enabled to support special i2s clock format like Intel's 100fs. ASRC function will track i2s clock and generate a corresponding system clock for codec. Calling this function helps select the clock source for both RT5663_AD_STEREO_FILTER and RT5663_DA_STEREO_FILTER filters which fixes the crackling sound.

2017-07-28arm64: mmu: Place guard page after mapping of kernel imageWill Deacon
The vast majority of virtual allocations in the vmalloc region are followed by a guard page, which can help to avoid overruning on vma into another, which may map a read-sensitive device. This patch adds a guard page to the end of the kernel image mapping (i.e. following the data/bss segments).

2017-07-27drm/i915: Force CPU synchronisation even if userspace requests ASYNCChris Wilson
The goal here was to minimise doing any thing or any check inside the kernel that was not strictly required. For a userspace that assumes complete control over the cache domains, the kernel is usually using outdated information and may trigger clflushes where none were required. However, swapping is a situation where userspace has no knowledge of the domain transfer, and will leave the object in the CPU cache. The kernel must flush this out to the backing storage prior to use with the GPU. As we use an asynchronous task tracked by an implicit fence for this, we also need to cancel the ASYNC flag on the object so that the object will wait for the clflush to complete before being executed. This also absolves userspace of the responsibility imposed by commit 77ae9957897d ("drm/i915: Enable userspace to opt-out of implicit fencing") that its needed to ensure that the object was out of the CPU cache prior to use on the GPU.

2017-07-27drm/i915: Only skip updating execobject.offset after errorChris Wilson
I was being overly paranoid in not updating the execobject.offset after performing the fallback copy where we set reloc.presumed_offset to -1. The thinking was to ensure that a subsequent NORELOC execbuf would be forced to process the invalid relocations. However this is overkill so long as we *only* update the execobject.offset following a successful update of the relocation value witin the batch. If we have to repeat the execbuf due to a later interruption, then we may skip the relocations on the second pass (honouring NORELOC) since the execobject.offset match the actual offsets (even though reloc.presumed_offset is garbage). Subsequent calls to execbuf with NORELOC should themselves ensure that the reloc.presumed_offset have been corrected in case of future migration. Reporting back the actual execobject.offset, even when reloc.presumed_offset is garbage, ensures that reuse of those objects use the latest information to avoid relocations.
