ALSA card) make current implementation legacy.
This includes renaming of existing files, some
variables, config options and documentation

Abstract the peripheral side ALSA sound card code from
the f_uac2 function into a component that can be called
by various functions, so the various flavors can be split
apart and selectively reused.
Visible changes:
- add uac_params structure to pass audio paramteres for
g_audio_setup
- make ALSA sound card's name configurable
- add [in/out]_ep_maxpsize
- allocate snd_uac_chip structure during g_audio_setup
- add u_audio_[start/stop]_[capture/playback] functions

After commit 7e4da3fcf7c9 ("usb: gadget: composite:
Test get_alt() presence instead of set_alt()") f_uac1
function became broken because it doesn't have
get_alt() callback implementation and composite
framework never set altsetting 1 for audiostreaming
interface. On host site it looks like:
[424339.017711] 21:1:1: usb_set_interface failed (-32)
Since host can't set altsetting 1, it can't start
playing audio.
In order to fix it implemented get_alt along with
minor improvements (error conditions checking)
similar to what existing f_uac2 has.

Simplify f_uac2 by removing platform driver/device
creation; use composite's usb_gadget device as
parent for sound card and for debug prints.
This removes extra layer of code without any functional
change.

Calculate wMaxPacketSize before endpoint matching the
descriptor is found.
This allows audio gadget to be used with controllers
which have a shortage or unavailability of endpoints
that can handle max packet size of 1023 (FS) or 1024
(HS).
With this audio gadget can be used on TI's OMAP-L138 SoC
which has a MUSB HS controller with endpoints having max
packet size much less than 1023 or 1024. See mode_2_cfg in
drivers/usb/musb/musb_core.c

There are only two requests for uac2, it may not be enough at high
loading system which usb interrupt handler can't be serviced on
time, then the data will be lost since it is isoc transfer for audio.
In this patch, we introduce a parameter for the number for usb request,
and the user can override it if current number for request is not enough
for his/her use case.
Besides, update this parameter for legacy audio gadget and documentation.

The default_length parameter of alloc_ep_req was not really necessary
and gadget drivers would almost always create an inline function to pass
the same value to len and default_len.
This patch removes that parameter and updates all calls to alloc_ep_req() to
use the new API.

Even if the /dev/hidg* chardev is automatically created, one
has to guess which one belongs to which function. In the case
of multiple HID functions, or maybe even multiple peripherals,
this becomes difficult.
Add the dev (with major and minor number) to configfs to allow
looking up (or even creating) the right device node for each
function. This file is read-only.

Add support for the UAC1 function with the configfs framework
along with following other changes:
- Add dynamic updation of AudioStreaming interface numbers in
the AudioControl interface descriptor.
- Add superspeed support.
- Stop playback on func disable so that pending request's
completion is called before request has been freed in unbind.
- Fix minor compilation issue.

In case config_ep_by_speed() returns error, endpoint descriptors
would not get populated. This results into NULL pointer dereference
when ep desc is accessed later. Fix this by bailing out set_alt if
config_ep_by_speed() API returns error.

The change protects almost the whole body of u_audio_iso_complete()
function by PCM stream lock, this is mainly sufficient to avoid a race
between USB request completion and stream termination, the change
prevents a possibility of invalid memory access in interrupt context
by memcpy():

Also added a check for potential !runtime condition, commonly it is
done by PCM_RUNTIME_CHECK(substream) in the beginning, however this
does not completely prevent from oopses in u_audio_iso_complete(),
because the proper protection scheme must be implemented in PCM
library functions.
An example of *not fixed* oops due to substream->runtime->*
dereference by snd_pcm_running(substream) from
snd_pcm_period_elapsed(), where substream->runtime is gone while
waiting the substream lock:

Substream period size potentially can be changed in runtime, however
this is not accounted in the data copying routine, the change replaces
the cached value with an actual value from substream runtime.
As a side effect the change also removes a potential division by zero
in u_audio_iso_complete() function, if there is a race with
uac_pcm_hw_free(), which sets prm->period_size to 0.

There is no necessity to copy PCM stream ring buffer area and size
properties to UAC private data structure, these values can be got
from substream itself.
The change gives more control on substream and avoid stale caching.

In u_audio_iso_complete, the runtime hw_ptr is updated before the
data is actually copied over to/from the buffer/dma area. When
ALSA uses this hw_ptr, the data may not actually be available to
be used. This causes trash/stale audio to play/record. This
patch updates the hw_ptr after the data has been copied to avoid
this.

in little-endian order. Use CPU<->LE helpers for
such fields.

This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.
Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card
f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.
f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.
f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.
Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.
Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.

This includes renaming of existing files, some

Abstract the peripheral side ALSA sound card code into a
component that can be called by various functions, so the
various flavors can be split apart and selectively reused.
Visible changes:
- add uac_params structure to pass audio paramteres for
g_audio_setup
- make ALSA sound card's name configurable
- add [in/out]_ep_maxpsize
- allocate snd_uac_chip structure during g_audio_setup
- add u_audio_[start/stop]_[capture/playback] functions
This change differs from opensource patch in that it does not
modify the UAC2 driver to use u_audio helper file for ALSA
sound card support.

After commit 7e4da3fcf7c9 ("usb: gadget: composite:
Test get_alt() presence instead of set_alt()") f_uac1
function became broken because it doesn't have
get_alt() callback implementation and composite
framework never set altsetting 1 for audiostreaming
interface. On host site it looks like:
[424339.017711] 21:1:1: usb_set_interface failed (-32)
Since host can't set altsetting 1, it can't start
playing audio.
In order to fix it implemented get_alt along with
minor improvements (error conditions checking)
similar to what existing f_uac2 has.

Upon driver unbind usb_free_all_descriptors() function frees all
speed descriptor pointers without setting them to NULL. In case
gadget speed changes (i.e from super speed plus to super speed)
after driver unbind only upto super speed descriptor pointers get
populated. Super speed plus desc still holds the stale (already
freed) pointer. As a result next composition switch results into
double free of super speed plus descriptor. Fix this issue by
setting all descriptor pointers to NULL after freeing them in
usb_free_all_descriptors(). Also clean up gsi_unbind() which is
setting up descriptor pointers to NULL already.

commit 9ae24af3669111d418242caec8dd4ebd9ba26860 upstream.
num can be indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/usb/gadget/function/f_mass_storage.c:3177 fsg_lun_make() warn:
potential spectre issue 'fsg_opts->common->luns' [r] (local cap)
Fix this by sanitizing num before using it to index
fsg_opts->common->luns
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

commit daa35bd95634a2a2d72d1049c93576a02711cb1a upstream.
When the gadget serial device has no associated TTY, do not pass any
received data into the TTY layer for processing; simply drop it instead.
This prevents the TTY layer from calling back into the gadget serial
driver, which will then crash in e.g. gs_write_room() due to lack of
gadget serial device to TTY association (i.e. a NULL pointer dereference).

If the user passes in a negative file size in a int64,
this will compare to be smaller than buffer length,
and it will get truncated to form a read length that
is larger than the buffer length.
To fix, return -EINVAL if the count argument is negative,
so the loop will never happen.
