ALSA: ctl: allow TLV read operation for callback type of element in locked case
A design of ALSA control core allows applications to execute three
operations for TLV feature; read, write and command. Furthermore, it
allows driver developers to process the operations by two ways; allocated
array or callback function. In the former, read operation is just allowed,
thus developers uses the latter when device driver supports variety of
models or the target model is expected to dynamically change information
stored in TLV container.
The core also allows applications to lock any element so that the other
applications can't perform write operation to the element for element
value and TLV information. When the element is locked, write and command
operation for TLV information are prohibited as well as element value.
Any read operation should be allowed in the case.
At present, when an element has callback function for TLV information,
TLV read operation returns EPERM if the element is locked. On the
other hand, the read operation is success when an element has allocated
array for TLV information. In both cases, read operation is success for
element value expectedly.
This commit fixes the bug. This change can be backported to v4.14
kernel or later.

this bug is not easy to be detected by users.
When problem happens, retire_capture_urb() could still be called
periodically, but the size of captured data is always 0, it could be
a firmware bug on the dock. Anyway I found after resuming, the

set_format() to set the interface and its endpoint, the capture
size will be normal again. This problem and workaound also apply to
playback.
To fix it in the kernel, add a quirk to let set_format() run

ALSA: Fix year 2038 issue for sound subsystem
This is a series I worked on with Baolin in 2017 and 2018, but we
never quite managed to finish up the last pieces. During the
ALSA developer meetup at ELC-E 2018 in Edinburgh, a decision was
made to go with this approach for keeping best compatibility
with existing source code, and then I failed to follow up by
resending the patches.
Now I have patches for all remaining time_t uses in the kernel,
so it's absolutely time to revisit them. I have done more
review of the patches myself and found a couple of minor issues
that I have fixed up, otherwise the series is still the same as
before.
Conceptually, the idea of these patches is:
- 64-bit applications should see no changes at all, neither
compile-time nor run-time.
- 32-bit code compiled with a 64-bit time_t currently
does not work with ALSA, and requires kernel changes and/or
sound/asound.h changes
- Most 32-bit code using these interfaces will work correctly
on a modified kernel, with or without the uapi header changes.
- 32-bit code using SNDRV_TIMER_IOCTL_TREAD requires the
updated header file for 64-bit time_t support
- 32-bit i386 user space with 64-bit time_t is broken for
SNDRV_PCM_IOCTL_STATUS, SNDRV_RAWMIDI_IOCTL_STATUS and
SNDRV_PCM_IOCTL_SYNC_PTR because of i386 alignment. This is also
addressed by the updated uapi header.
- PCM mmap is currently supported on native x86 kernels
(both 32-bit and 64-bit) but not for compat mode. This series breaks
the 32-bit native mmap support for 32-bit time_t, but instead allows
it for 64-bit time_t on both native and compat kernels. This seems to
be the best trade-off, as mmap support is optional already, and most
32-bit code runs in compat mode anyway.
- I've tried to avoid breaking compilation of 32-bit code
as much as possible. Anything that does break however is likely code
that is already broken on 64-bit time_t and needs source changes to
fix them.

ALSA: cmipci: Allow disabling MPU port via module option
Patrick May reported that his sound card with CMI8378 chip causes a
crash / reboot when accessing the MIDI port that isn't actually
present on the board. Moreover, despite of the documentation,
passing mpu_port=0 doesn't disable the MIDI port on this board.
It implies that the chip is a newer revision and the MPU401 port is
integrated and mapped on the PCI register. For this chip model, the
driver enables the MPU port unconditionally, so far.
Although fixing the unexpected reboot would be the best solution, it's
not so trivial to identify the cause. So, as a plan B, this patch
extends the existing mpu_port option usage to allow disabling the port
by specifying the value 0, just like we applied for fm_port option in
commit
2f24d159d5ac ("[ALSA] cmipci - Allow to disable integrated FM
port"). As default, the MPU port is still enabled, but user can pass
mpu_port=0 to disable it.

ALSA: hda: Fix regression by strip mask fix
The commit
e38e486d66e2 ("ALSA: hda: Modify stream stripe mask only
when needed") tried to address the regression by the unconditional
application of the stripe mask, but this caused yet another
regression for the previously working devices. Namely, the patch
clears the azx_dev->stripe flag at snd_hdac_stream_clear(), but this
may be called multiple times before restarting the stream, so this
ended up with clearance of the flag for the whole time.
This patch fixes the regression by moving the azx_dev->stripe flag
clearance at the counter-part, the close callback of HDMI codec
driver instead.

Since this is a common problem, this patch simply adds the clearance

ALSA: add new 32-bit layout for snd_pcm_mmap_status/control
The snd_pcm_mmap_status and snd_pcm_mmap_control interfaces are one of the
trickiest areas to get right when moving to 64-bit time_t in user space.
The snd_pcm_mmap_status structure layout is incompatible with user space
that uses a 64-bit time_t, so we need a new layout for it. Since the
SNDRV_PCM_IOCTL_SYNC_PTR ioctl combines it with snd_pcm_mmap_control
into snd_pcm_sync_ptr, we need to change those two as well.
Both structures are also exported via an mmap() operation on certain
architectures, and this suffers from incompatibility between 32-bit
and 64-bit user space. As we have to change both structures anyway,
this is a good opportunity to fix the mmap() problem as well, so let's
standardize on the existing 64-bit layout of the structure where possible.
The downside is that we lose mmap() support for existing 32-bit x86 and
powerpc applications, adding that would introduce very noticeable runtime
overhead and complexity. My assumption here is that not too many people
will miss the removed feature, given that:
- Almost all x86 and powerpc users these days are on 64-bit kernels,
the majority of today's 32-bit users are on architectures that never
supported mmap (ARM, MIPS, ...).
- It never worked in compat mode (it was intentionally disabled there)
- The application already needs to work with a fallback to
SNDRV_PCM_IOCTL_SYNC_PTR, which will keep working with both the old
and new structure layout.
Both the ioctl() and mmap() based interfaces are changed at the same
time, as they are based on the same structures. Unlike other interfaces,
we change the uapi header to export both the traditional structure and
a version that is portable between 32-bit and 64-bit user space code
and that corresponds to the existing 64-bit layout. We further check the
__USE_TIME_BITS64 macro that will be defined by future C library versions
whenever we use the new time_t definition, so any existing user space
source code will not see any changes until it gets rebuilt against a new
C library. However, the new structures are all visible in addition to the
old ones, allowing applications to explicitly request the new structures.
In order to detect the difference between the old snd_pcm_mmap_status and
the new __snd_pcm_mmap_status64 structure from the ioctl command number,
we rely on one quirk in the structure definition: snd_pcm_mmap_status
must be aligned to alignof(time_t), which leads the compiler to insert
four bytes of padding in struct snd_pcm_sync_ptr after 'flags' and a
corresponding change in the size of snd_pcm_sync_ptr itself. On x86-32
(and only there), the compiler doesn't use 64-bit alignment in structure,
so I'm adding an explicit pad in the structure that has no effect on the
existing 64-bit architectures but ensures that the layout matches for x86.
The snd_pcm_uframes_t type compatibility requires another hack: we can't
easily make that 64 bit wide, so I leave the type as 'unsigned long',
but add padding before and after it, to ensure that the data is properly
aligned to the respective 64-bit field in the in-kernel structure.
For the SNDRV_PCM_MMAP_OFFSET_STATUS/CONTROL constants that are used
as the virtual file offset in the mmap() function, we also have to
introduce new constants that depend on hte __USE_TIME_BITS64 macro:
The existing macros are renamed to SNDRV_PCM_MMAP_OFFSET_STATUS_OLD
and SNDRV_PCM_MMAP_OFFSET_CONTROL_OLD, they continue to work fine on
64-bit architectures, but stop working on native 32-bit user space.
The replacement _NEW constants are now used by default for user space
built with __USE_TIME_BITS64, those now work on all new kernels for x86,
ppc and alpha (32 and 64 bit, native and compat). It might be a good idea
for a future alsa-lib to support both the _OLD and _NEW macros and use
the corresponding structures directly. Unmodified alsa-lib source code
will retain the current behavior, so it will no longer be able to use
mmap() for the status/control structures on 32-bit systems, until either
the C library gets updated to 64-bit time_t or alsa-lib gets updated to
support both mmap() layouts.

The struct snd_pcm_status will use 'timespec' type variables to record

Userspace will use SNDRV_PCM_IOCTL_STATUS and SNDRV_PCM_IOCTL_STATUS_EXT

userspace. The command number is always defined through _IOR/_IOW/IORW,
so when userspace changes the definition of 'struct timespec' to use

Thus in the kernel, we now need to define two versions of each such ioctl
and corresponding ioctl commands to handle 32bit time_t and 64bit time_t
in native mode:
struct snd_pcm_status32 {
......
s32 trigger_tstamp_sec;

s32 trigger_tstamp_nsec;
......

snd_pcm_status_user32() are used to handle 32bit time_t in compat mode.
'struct compat_snd_pcm_status64' and snd_pcm_status_user_compat64() are used
to handle 64bit time_t.
The implicit padding before timespec is made explicit to avoid incompatible
structure layout between 32-bit and 64-bit x86 due to the different
alignment requirements, and the snd_pcm_status structure is now hidden
from the kernel to avoid relying on the timespec definitio definitionn
Finally we can replace SNDRV_PCM_IOCTL_STATUS and SNDRV_PCM_IOCTL_STATUS_EXT
with new commands and introduce new functions to fill new 'struct snd_pcm_status64'
instead of using unsafe 'struct snd_pcm_status'. Then in future, the new
commands can be matched when userspace changes 'timespec' to 64bit type
to make a size change of 'struct snd_pcm_status'. When glibc changes time_t
