2015-11-14ALSA: dice: fix detection of Loud devicesTakashi Sakamoto1-0/+4
Commit a471fcde8c2c ("ALSA: dice: fix detection of Weiss devices") adds a quirk of Weiss models. According to users' reports, Loud models also have the similar quirk. They have 0x10 in the category field. This commit adds support for Mackie Onyx Blackbird and Onyx-i series. As long as I know, Dice-based models produced by Focusrite/Alesis/PreSonus/M-Audio/TC Electronic have default value (0x04) in their category field, thus it may be reasonable to add a condition statement for Loud models, instead of removing the check of category value.

2015-11-12ALSA: pci: depend on ZONE_DMADan Williams1-12/+12
There are several sound drivers that 'select ZONE_DMA'. This is backwards as ZONE_DMA is an architecture capability exported to drivers. Switch the polarity of the dependency to disable these drivers when the architecture does not support ZONE_DMA. This was discovered in the context of testing/enabling devm_memremap_pages() which depends on ZONE_DEVICE. ZONE_DEVICE in turn depends on !ZONE_DMA.

2015-11-12ALSA: hda - Simplify phantom jack handling for HDMI/DPTakashi Iwai3-19/+8
The HDMI codec parser may create a phantom jack, but the helper function snd_hda_jack_add_kctl() treats always as a normal jack. This is superfluous as the jack query is executed at each time the jack sync is performed. Since the HDMI codec parser is the only caller of this function, it's easier to change back this directly calling the original __snd_hda_jack_add_kctl() with phantom_jack parameter.

2015-10-30ALSA: firewire-digi00x: add another rawmidi character device for MIDI control portsTakashi Sakamoto1-54/+50
Digi 002/003 family uses two ways to transfer MIDI messages. They're different mechanisms, while it's better to handle the ways in different ALSA rawmidi character devices because one character device has just a set of operations. This commit adds another rawmidi character device for control MIDI port. As a result, first rawmidi character device is just for MIDI messages transferred by isochronous packets.

2015-10-30ALSA: firewire-digi00x: add MIDI operations for MIDI control portTakashi Sakamoto1-0/+63
Digi 002/003 family has two types of MIDI port; one is for physical MIDI port and another is for MIDI control message. The former is transferred in isochronous packet, and the latter is transferred by asynchronous transaction. These transmission mechanisms are completely different, while current ALSA digi00x driver defines a set of operations for them with several condition statements. As a result, codes for the operation are messy. This commit adds a set of MIDI operation for control MIDI ports. In later commit, it's applied as an operation for ALSA rawmidi character device.

2015-10-27ALSA: hda - Disable 64bit address for Creative HDA controllersTakashi Iwai1-0/+3
We've had many reports that some Creative sound cards with CA0132 don't work well. Some reported that it starts working after reloading the module, while some reported it starts working when a 32bit kernel is used. All these facts seem implying that the chip fails to communicate when the buffer is located in 64bit address. This patch addresses these issues by just adding AZX_DCAPS_NO_64BIT flag to the corresponding PCI entries. I casually had a chance to test an SB Recon3D board, and indeed this seems helping. Although this hasn't been tested on all Creative devices, it's safer to assume that this restriction applies to the rest of them, too. So the flag is applied to all Creative entries.

2015-10-23dm cache: the CLEAN_SHUTDOWN flag was not being setJoe Thornber1-1/+1
If the CLEAN_SHUTDOWN flag is not set when a cache is loaded then all cache blocks are marked as dirty and a full writeback occurs. __commit_transaction() is responsible for setting/clearing CLEAN_SHUTDOWN (based the flags_mutator that is passed in). Fix this issue, of the cache's on-disk flags being wrong, by making sure __commit_transaction() does not reset the flags after the mutator has altered the flags in preparation for them being serialized to disk. before: sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); disk_super->flags = cpu_to_le32(cmd->flags); after: disk_super->flags = cpu_to_le32(cmd->flags); sb_flags = mutator(le32_to_cpu(disk_super->flags)); disk_super->flags = cpu_to_le32(sb_flags); Reported-by: Bogdan Vasiliev <bogdan.vasiliev@gmail.com> Signed-off-by: Joe Thornber <ejt@redhat.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: stable@vger.kernel.org

2015-10-23dm btree remove: fix a bug when rebalancing nodes after removalJoe Thornber1-6/+11
Commit 4c7e309340ff ("dm btree remove: fix bug in redistribute3") wasn't a complete fix for redistribute3(). The redistribute3 function takes 3 btree nodes and shares out the entries evenly between them. If the three nodes in total contained (MAX_ENTRIES * 3) - 1 entries between them then this was erroneously getting rebalanced as (MAX_ENTRIES - 1) on the left and right, and (MAX_ENTRIES + 1) in the center. Fix this issue by being more careful about calculating the target number of entries for the left and right nodes.

2015-10-24ASoC: rt5645: Add the HWEQ for the speaker outputOder Chiou1-0/+110
The patch adds the HWEQ function for the speaker output. User can set the HWEQ parameters using the ALSA binary control byte-by-byte. We use the following struct array to store the HWEQ parameters for implementing as simple as possible. struct rt5645_eq_param_s { unsigned short reg; unsigned short val; }; It supports the variant length of the HWEQ parameters that are required. We add the validating function in the function "rt5645_hweq_put" of the ALSA binary control to avoid the user that puts the invalid parameters. In the HWEQ enable function of speaker event, we also add the validating function to prevent that the invalid parameters are applied to codec. The HWEQ parameters should be controlled by DAPM for a specific sequence, so the parameters will be applied to the codec in the speaker power up event of DAPM, and will be disabled in the speaker power down event of DAPM.

Mapping an image with a long parent chain (e.g. image foo, whose parent is bar, whose parent is baz, etc) currently leads to a kernel stack overflow, due to the following recursion in the reply path: rbd_osd_req_callback() rbd_obj_request_complete() rbd_img_obj_callback() rbd_img_parent_read_callback() rbd_obj_request_complete() ...

Currently we leak parent_spec and trigger a "parent reference underflow" warning if rbd_dev_create() in rbd_dev_probe_parent() fails. The problem is we take the !parent out_err branch and that only drops refcounts; parent_spec that would've been freed had we called rbd_dev_unparent() remains and triggers rbd_warn() in rbd_dev_parent_put() - at that point we have parent_spec != NULL and parent_ref == 0, so counter ends up being -1 after the decrement.

2015-10-23mm: make sendfile(2) killableJan Kara1-4/+5
Currently a simple program below issues a sendfile(2) system call which takes about 62 days to complete in my test KVM instance. int fd; off_t off = 0; fd = open("file", O_RDWR | O_TRUNC | O_SYNC | O_CREAT, 0644); ftruncate(fd, 2); lseek(fd, 0, SEEK_END); sendfile(fd, fd, &off, 0xfffffff); Now you should not ask kernel to do a stupid stuff like copying 256MB in 2-byte chunks and call fsync(2) after each chunk but if you do, sysadmin should have a way to stop you. We actually do have a check for fatal_signal_pending() in generic_perform_write() which triggers in this path however because we always succeed in writing something before the check is done, we return value > 0 from generic_perform_write() and thus the information about signal gets lost. Fix the problem by doing the signal check before writing anything. That way generic_perform_write() returns -EINTR, the error gets propagated up and the sendfile loop terminates early.
