ALSA: pcm: Avoid possible info leaks from PCM stream buffers
The current PCM code doesn't initialize explicitly the buffers
allocated for PCM streams, hence it might leak some uninitialized

buffer before actually starting the stream.
Since this is a common problem, this patch simply adds the clearance
of the buffer data at hw_params callback. Although this does only
zero-clear no matter which format is used, which doesn't mean the
silence for some formats, but it should be OK because the intention is

The auto-parser assigns the bass speaker to DAC3 (NID 0x06) which
is without the volume control. I do not see a reason to use DAC2,
because the shared output to all speakers produces the sufficient
and well balanced sound. The stereo support is enough for this
purpose (laptop).
Commit 4d08690e6bab ("ALSA: hda - Add DP-MST support for NVIDIA codecs")
introduced a slight change of behaviour how non-MST monitors are
assigned to PCMs on Intel platforms.
In the drm_audio_component.h interface, the third parameter
to pin_eld_notify() is pipe number. On Intel platforms, this value
is -1 for MST. On other platforms, a non-zero pipe id is used to
signal MST use.
This difference leads to some subtle differences in hdmi_find_pcm_slot()
with regards to how non-MST monitors are assigned to PCMs.
This patch restores the original behaviour on Intel platforms while
keeping the new allocation policy on other platforms.
Add additional check in hdmi_find_pcm_slot() to not return
a pcm index that points to unallocated pcm. This could happen
if codec driver is set up in codec->mst_no_extra_pcms mode.
On some platforms, this leads to a kernel oops in snd_ctl_notify(),
called via update_eld().
We've added the bass speaker support on Acer 8951G by the commit ec319f125e50 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems

to power up the amp, the actual hardware reacts other way round,

ALSA: pcm: Add the support for sync-stop operation
The standard programming model of a PCM sound driver is to process
snd_pcm_period_elapsed() from an interrupt handler. When a running
stream is stopped, PCM core calls the trigger-STOP PCM ops, sets the
stream state to SETUP, and moves on to the next step. This is
performed in an atomic manner -- this could be called from the interrupt
context, after all.
The problem is that, if the stream goes further and reaches to the
CLOSE state immediately, the stream might be still being processed in
snd_pcm_period_elapsed() in the interrupt context, and hits a NULL
dereference. Such a crash happens because of the atomic operation,
and we can't wait until the stream-stop finishes.

ALSA: pcm: Allow NULL ioctl ops
Currently PCM ioctl ops is a mandatory field but almost all drivers
simply pass snd_pcm_lib_ioctl. For simplicity, allow to set NULL in
the field and call snd_pcm_lib_ioctl() as default.
This patch adds the support for the feature to automatically allocate
and free PCM buffers, so called "managed buffer allocation" mode.
It's set up via new PCM helpers, snd_pcm_set_managed_buffer() and
snd_pcm_set_managed_buffer_all(), both of which correspond to the
existing preallocator helpers, snd_pcm_lib_preallocate_pages() and
snd_pcm_lib_preallocate_pages_for_all(). When the new helper is used,
it not only performs the pre-allocation of buffers, but also it
manages to call snd_pcm_lib_malloc_pages() before the PCM hw_params
ops and snd_lib_pcm_free() after the PCM hw_free ops inside PCM core,
respectively. This allows drivers to drop the explicit calls of the
memory allocation / release functions, and it will be a good amount of
code reduction in the end of this patch series.
When the PCM substream is set to the managed buffer allocation mode,
the managed_buffer_alloc flag is set in the substream object. Since
some drivers want to know when a buffer is newly allocated or
re-allocated at hw_params callback (e.g. want to set up the additional
stuff for the given buffer only at allocation time), now PCM core
turns on buffer_changed flag when the buffer has changed.
The standard conversions to use the new API will be straightforward:
- Replace snd_pcm_lib_preallocate*() calls with the corresponding
snd_pcm_set_managed_buffer*(); the arguments should be unchanged
- Drop superfluous snd_pcm_lib_malloc() and snd_pcm_lib_free() calls;
the check of snd_pcm_lib_malloc() returns should be replaced with
the check of runtime->buffer_changed flag.
- If hw_params or hw_free becomes empty, drop them from PCM ops

and removes it by snd_soc_romove_dai_link().
This snd_soc_add/remove_dai_link() and/or its related
functions are unbalanced before, and now, these are balance-uped.
But, it finds the random operation issue, and it is reported by
Pierre-Louis.
When card was released, topology will call snd_soc_remove_dai_link()
via (A).
/* This should be called before snd_card_free() */
(A) soc_remove_link_components(card);
/* free the ALSA card at first; this syncs with pending operations */

(X) soc_remove_link_dais(card);
/* need to sync the delayed work before releasing resources */
flush_delayed_work(&rtd->delayed_work);
snd_soc_pcm_component_free(rtd);
}
Here, it gets rtd via pcm->private_data.
But, topology related rtd are already freed at (A).
Normal sound card has no damage, becase it frees rtd at (C).
These are finalizing rtd related data.
Thus, these should be called when rtd was freed, not sound card
was freed. It is very natural and understandable.
In other words, pcm->private_free = soc_pcm_private_free()
is no longer needed.
Extra issue is that there is zero chance to call
soc_remove_dai() for topology related dai at (X).
Because (A) removes rtd connection from card too, and,
(X) is based on card connected rtd.
This means, (X) need to be called before (C) (= for normal sound)
and (A) (= for topology).
Now, I want to focus this patch which is the reason why
snd_card_free() = (B) is located there.
Original snd_card_free() was called last of this function.
But moved to top to avoid use-after-free issue.
The issue was happen at soc_pcm_free() which was pcm->private_free,
today it is updated/renamed to soc_pcm_private_free().
In other words, (B) need to be called before (C) (= for normal sound)
and (A) (= for topology), because it needs (not yet freed) rtd.
But, (A) need to be called before (B),
because it needs card->snd_card pointer.
If we call flush_delayed_work() and snd_soc_pcm_component_free()
(= same as soc_pcm_private_free()) when rtd was freed (= (C), (A)),
there is no reason to call snd_card_free() at top of this function.
It can be called end of this function, again.
But, in such case, it will likely break unbind again, as Takashi-san
reported. When unbind is performed in a busy state, the code may
release still-in-use resources.
At least we need to call snd_card_disconnect_sync() at the first place.

Once the Device Entry is selected, all subsequent Pin Widget verbs
controlling the sink device will be directed to the selected Device
Entry until the Device Select verb is updated with a new value.
These Pin Widget verbs include:
* Connection Select
* Get Connection List Entry
* Amplifier Gain/Mute
* Power State
* Pin Widget Control
* ELD Data
* DIP-Size
* DIP-Index
* DIP-Data
* DIP-XmitCtrl
* Content Protection Control
* ASP Channel Mapping
This patch adds calls to snd_hda_set_dev_select() to direct each of
these Pin Widget control verbs to the correct Device Entry.
snd_hda_get_connections() does not return per-device connection
list, therefore make use snd_hda_get_raw_connections() instead of
snd_hda_get_connections().

ALSA: hda - Add DP-MST jack support
This patch adds DP-MST jack support which will be used on NVIDIA
platforms. Today, DP-MST audio is supported only if the codec has
acomp support. This patch makes it possible to add DP-MST support
for non-acomp codecs.
For the codecs supporting DP-MST audio, each pin can contain several
device entries. Each device entry is a virtual pin, described by
pin_nid and dev_id in struct hdmi_spec_per_pin. For monitor hotplug
event handling, non-acomp codecs enable and register jack-detection
for every hdmi_spec_per_pin.
This patch updates every relevant function in hda_jack.h and its
implementation in hda_jack.c, to consider dev_id along with pin_nid.
Changes to the HD Audio specification to support DP-MST audio are
described in the Intel Document Change Notification (DCN) number
HDA040-A.
From HDA040-A, "For the case of multi stream capable Digital Display
Pin Widget, [the Get Pin Sense verb] can be used to read a specific
Device Entry state as reported in Get Device List Entry verb." This
patch updates the read_pin_sense() function to take the dev_id as an
argument and pass it as a parameter to the Get Pin Sense verb.
Bits 15 through 20 from the Unsolicited Response for intrinsic
events contain the index of the Device Entry that generated the
event. This patch updates the Unsolicited Response event handlers to
extract the device entry index from the response and pass it to
snd_hda_jack_tbl_get_from_tag().
This patch updates snd_hda_jack_tbl_new() to take a dev_id argument
and store it in the jack structure, and to make sure not to generate
a different tag when called more than once for the same nid.

ALSA: compress: add flac decoder params
The current design of sending codec parameters assumes that decoders
will have parsers so they can parse the encoded stream for parameters
and configure the decoder.
But this assumption may not be universally true and we know some DSPs
which do not contain the parsers so additional parameters are required
to be passed.
So add these parameters starting with FLAC decoder. The size of
snd_codec_options is still 120 bytes after this change (due to this
being a union)

ipmr: Fix skb headroom in ipmr_get_route().
In route.c, inet_rtm_getroute_build_skb() creates an skb with no
headroom. This skb is then used by inet_rtm_getroute() which may pass
it to rt_fill_info() and, from there, to ipmr_get_route(). The later
might try to reuse this skb by cloning it and prepending an IPv4
header. But since the original skb has no headroom, skb_push() triggers
skb_under_panic():
Actually the original skb used to have enough headroom, but the
reserve_skb() call was lost with the introduction of
inet_rtm_getroute_build_skb() by commit e75f21eac8e4 ("ipv4: support
sport, dport and ip_proto in RTM_GETROUTE").
We could reserve some headroom again in inet_rtm_getroute_build_skb(),
but this function shouldn't be responsible for handling the special
case of ipmr_get_route(). Let's handle that directly in
ipmr_get_route() by calling skb_realloc_headroom() instead of
skb_clone().
