ALSA: core: Assure control device to be registered at last
The commit
289ca025ee1d ("ALSA: Use priority list for managing device
list") changed the way to register/disconnect/free devices via a
single priority list. This helped to make behavior consistent, but it
also changed a slight behavior change: namely, the control device is
registered earlier than others, while it was supposed to be the very
last one.
I've put SNDRV_DEV_CONTROL in the current position as the release of
ctl elements often conflict with the private ctl elements some PCM or
other components may create, which often leads to a double-free.
But, the order of register and disconnect should be indeed fixed as
expected in the early days: the control device gets registered at
last, and disconnected at first.
This patch changes the priority list order to move SNDRV_DEV_CONTROL
as the last guy to assure the register / disconnect order. Meanwhile,
for keeping the messy resource release order, manually treat the
control and lowlevel devices as last freed one.
Additional note:
The lowlevel device is the device where a card driver creates at
probe. And, we still keep the release order control -> lowlevel, as
there might be link from a control element back to a lowlevel object.

ALSA: control: fix a redundant-copy issue
In snd_ctl_elem_add_compat(), the fields of the struct 'data' need to be
copied from the corresponding fields of the struct 'data32' in userspace.
This is achieved by invoking copy_from_user() and get_user() functions. The
problem here is that the 'type' field is copied twice. One is by
copy_from_user() and one is by get_user(). Given that the 'type' field is
not used between the two copies, the second copy is *completely* redundant
and should be removed for better performance and cleanup. Also, these two
copies can cause inconsistent data: as the struct 'data32' resides in
userspace and a malicious userspace process can race to change the 'type'

ALSA: usb-audio: Add "Keep Interface" control
This patch adds "Keep Interface" control for each USB-audio device.
The control element is with SND_CTL_IFACE_CARD, so that it won't
appear on any sane mixer applications. For a device that is confirmed
to work well with "keep-interface" mode, user can flip the control via
amixer, e.g.
% amixer -c1 cset iface=CARD,name='Keep Interface' on
and save/restore the state via alsactl.
The reason to provide this via control API is that the behavior must
be pretty depending on the device (and the firmware in it), so it's
not ideal to apply via module option.
For a device that certainly works, we may set it statically via a
quirk table entry. But a device like Dell WD15 dock behaves so
differently depending on the firmware, and we can't set it
statically. So leave this as a dynamic switch each user can adjust
freely.

As of this patch, the flag is nowhere set, so it's just a place

A background information for this change:
Dell WD15 dock with Realtek chip gives a very long pause at each time
the driver changes the altset, which eventually happens at every PCM
stream open/close and parameter change. As the long pause happens in
each usb_set_interface() call, there is nothing we can do as long as
it's called. The workaround is to reduce calling it as much as
possible, and this flag indicates that behavior.

ALSA: dice: fix kernel NULL pointer dereference due to invalid calculation for array index
At a commit
f91c9d7610a ('ALSA: firewire-lib: cache maximum length of
payload to reduce function calls'), maximum size of payload for tx
isochronous packet is cached to reduce the number of function calls.
This cache was programmed to updated at a first callback of ohci1394 IR
context. However, the maximum size is required to queueing packets before
starting the isochronous context.
As a result, the cached value is reused to queue packets in next time to
starting the isochronous context. Then the cache is updated in a first
callback of the isochronous context. This can cause kernel NULL pointer
dereference in a below call graph:
(sound/firewire/amdtp-stream.c)
amdtp_stream_start()
->queue_in_packet()
->queue_packet()
(drivers/firewire/core-iso.c)
->fw_iso_context_queue()
->struct fw_card_driver.queue_iso()
(drivers/firewire/ohci.c)
= ohci_queue_iso()
->queue_iso_packet_per_buffer()
buffer->pages[page]
The issued dereference occurs in a case that:
- target unit supports different stream formats for sampling transmission
frequency.
- maximum length of payload for tx stream in a first trial is bigger
than the length in a second trial.
In this case, correct number of pages are allocated for DMA and the 'pages'
array has enough elements, while index of the element is wrongly calculated
according to the old value of length of payload in a call of
'queue_in_packet()'. Then it causes the issue.
This commit fixes the critical bug. This affects all of drivers in ALSA
firewire stack in Linux kernel v4.12 or later.

ALSA: seq: Fix races at MIDI encoding in snd_virmidi_output_trigger()
The sequencer virmidi code has an open race at its output trigger
callback: namely, virmidi keeps only one event packet for processing
while it doesn't protect for concurrent output trigger calls.
snd_virmidi_output_trigger() tries to process the previously
unfinished event before starting encoding the given MIDI stream, but
this is done without any lock. Meanwhile, if another rawmidi stream
starts the output trigger, this proceeds further, and overwrites the
event package that is being processed in another thread. This
eventually corrupts and may lead to the invalid memory access if the
event type is like SYSEX.
The fix is just to move the spinlock to cover both the pending event
and the new stream.
The bug was spotted by a new fuzzer, RaceFuzzer.

ALSA: hda - Skip jack and others for non-existing PCM streams
When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.
The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams. This results in confusion on user-space, and even may
break the operation.
Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.
This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.

different approach:
- For dp->synths[], change the helpers to retrieve seq_oss_synthinfo
pointer directly instead of the array expansion at each place
- For info->ch[], harden in a normal way, as there are only a couple
of places
As a result, the existing helper, snd_seq_oss_synth_is_valid() is
replaced with snd_seq_oss_synth_info(). Also, we cover MIDI device
where a similar array expansion is done, too, although it wasn't

ALSA: dice: improve support for ancient firmware for DICE
In early stage of firmware SDK, DICE seems to lose its backward
compatibility due to some registers on global address section. I found
this with Alesis Multimix 12 FireWire with ancient firmware (approx.
shipped version).
According to retrieved log from the unit, global section has 96 byte
space. On the other hand, current version of ALSA dice driver assumes
that all of supported unit has at least 100 byte space.
$ ./firewire-request /dev/fw1 read 0xffffe0000000 28
result: 000: 00 00 00 0a 00 00 00 18 00 00 00 22 00 00 00 8a
result: 010: 00 00 00 ac 00 00 01 12 00 00 00 00 00 00 00 00
result: 020: 00 00 00 00 00 00 00 00
This commit adds support for the ancient firmware. Check of global section
is loosened to accept the smaller space. The lack of information is
already compensated by hard-coded parameters.
I experienced that the latest version of Windows driver for this model
can't handle this unit, too. This means that TCAT releases firmware SDK
without backward compatibility for the ancient firmware.
Below list is a early history of driver/firmware package released by
Alesis. I investigated on wayback machine on Internet Archive:
* Unknown: PAL v1.0.41.2, firmware v1.0.3
* Mar 2006: PAL v1.54.0, firmware v1.0.4
* Dec 2006: PAL v2.0.0.2, firmware v2.0
* Jun 2007: PAL v3.0.41.5, firmware v2.0
* Jul 2007: PAL v3.0.56.2. firmware v2.0
* Jan 2008: PAL v3.0.81.1080, firmware v2.0
If I can assume that firmware version is the same as DICE version, DICE
version for the issued firmware may be v1.0.3. According to code base of
userspace driver project (FFADO), I can read DICE v1.0.4 supports global
space larger than 100 byte. I guess the smaller space of global section is
a feature of DICE v1.0.3.

ALSA: usb-audio: Skip broken EU on Dell dock USB-audio
The Dell Dock USB-audio device with 0bda:4014 is behaving notoriously
bad, and we have already applied some workaround to avoid the firmware
hiccup. Yet we still need to skip one thing, the Extension Unit at ID
4, which doesn't react correctly to the mixer ctl access.

ALSA: usb-audio: Fix missing endian conversion
The UAC2 jack detection support introduced the bmControls checks in a
couple of places, but they forgot the endian conversion; the
bmControls of UAC2 terminal descriptor is __le16, not a byte like in
UAC1.

ALSA: usb-audio: Fix forgotten conversion of control query functions
The recent code refactoring made the argument for some helper
functions to be the explicit UAC_CS_* and UAC2_CS_* value instead of
0-based offset. However, there was one place left forgotten, and it
caused a regression on some devices appearing as the inconsistent
mixer setup.
This patch corrects the forgotten conversion.
