pstream: fix revoke callback setting
While investigating bug 95352, I noticed that
pa_pstream_set_revoke_callback() and pa_pstream_set_release_callback()
were identical - both set the release callback.
pa_pstream_set_revoke_callback() was obviously broken - it was setting
the wrong callback.
The only place where set_revoke_callback() is called is in
protocol-native.c. The code there looks like this:
pa_pstream_set_revoke_callback(c->pstream, pstream_revoke_callback, c);
pa_pstream_set_release_callback(c->pstream, pstream_release_callback, c);
Since set_release_callback() is called last, the release callback gets
set correctly. The only problem is that the revoke callback stays
unset. What are the consequences of that? The code that calls the
revoke callback looks like this:
if (p->revoke_callback)
p->revoke_callback(p, block_id, p->revoke_callback_userdata);
else
pa_pstream_send_revoke(p, block_id);
So the intended callback is replaced with a pa_pstream_send_revoke()
call. What does the intended callback, that doesn't get called, do?
if (!(q = pa_thread_mq_get()))
pa_pstream_send_revoke(p, block_id);
else
pa_asyncmsgq_post(q->outq, PA_MSGOBJECT(userdata), CONNECTION_MESSAGE_REVOKE, PA_UINT_TO_PTR(block_id), 0, NULL, NULL);
So the native protocol's revoke callback is anyway going to call
pa_pstream_send_revoke() when called from the main thread. If the
revoking is done from an IO thread, an asynchronous message is sent to
the main thread instead, and the message handler will then call
pa_pstream_send_revoke().
In conclusion, the only effect of this bug was that
pa_pstream_send_revoke() was sometimes being called from an IO thread
when it should have been called from the main thread. I don't know if
this caused the crash in bug 95352. Probably not.

the asynchronous subscription system. Previously handle_load_module()
created the new pa_dbusiface_module object before we got
a notification of the loading of the module, but now we get the
notification already within the pa_module_load() call. That resulted
in a crash, because the module_new_cb() created the
pa_dbusiface_module object before pa_module_load() returned, and then
handle_load_module() would create another pa_dbusiface_module object
for the same module.
This patch removes the pa_dbusiface_module_new() call from
handle_load_module(). module_new_cb() is now responsible for all
pa_dbusiface_module object creations, except the ones that are created
during the initialization of module-dbus-protocol.

Disable LFE remixing by default
The current LFE crossover filter removes low frequencies from the main
channels and puts them into the LFE channel with the wrong amplitude.
It is not known for sure what is the correct relative amplitude (acoustic
measurements are required with real hardware), and changing that might
introduce a new bug, "it clips the LFE channel".
So just disable the feature by default until a better understanding
emerges how it should work. This, essentially, returns the defaults
to their state as of PulseAudio 6.0.
Some more observations:
- Most of available active analog speakers on the market do the
necessary crossover filtering already, and HDMI receivers can be
configured to do that, too, so a crossover filter in PulseAudio is
harmful in these use cases.
- The "laptop with a builtin subwoofer" use case requires manual
configuration anyway because the default crossover frequency (120 Hz) is
wrong for laptop speakers.
- Finally, Windows 10 with a built-in USB audio driver does not synthesize
the LFE channel given a 5.1 card and a stereo audio stream by default.

switch-on-port-available: prefer ports that have been selected by the user
Let's assume that there are two output ports, and they are on
different profiles:
* Integrated speakers (priority: 10000, available)
* HDMI (priority: 5900, not available)
Then the user plugs in an HDMI monitor with speakers. Since the HDMI
priority is lower than the speaker priority, we don't route to HDMI by
default. However, the user manually switches the profile to use the
HDMI output.
Then the user plugs out the monitor, so we switch back to speakers.
When the monitor is plugged back in, the user needs to manually switch
the audio output again. That should be improved: if the user preferred
to the HDMI output over the speakers, we should remember that and
automatically switch to HDMI whenever it becomes available.
The lack of automatic switching is even worse when the monitor goes to
a sleep mode after some period of inactivity. The monitor audio may
become unavailable, and PulseAudio can't distinguish that from the
case where the monitor is physically unplugged. Even worse, the
monitor may become unavailable for a short while when adjusting the
display parameters (for example, media center software may adjust the
display parameters to match the media that is being played back). In
these cases we clearly should switch automatically back to HDMI when
it becomes available again.

and pa_card.preferred_output_port when the user changes the card
profile or a port, and switching to the preferred port when it becomes

device-manager, filter-apply: don't reroute streams that have a filter
device-manager reroutes all streams whenever a new device appears.
When filter-apply has loaded a filter for some stream, the filter
device may not be what device-manager considers the best device for
the stream, which means that when an unrelated device appears,
device-manager may break the filtering that filter-apply had set up.
This patch changes filter-apply so that it saves the filter device
name to the stream proplist when it sets up a filter. device-manager
can then check the proplist when it does rerouting, and skip the
rerouting for streams that have a filter applied to them.
The proplist isn't cleaned up when the stream moves away from the
filter device, so before doing any decisions based on the
filter_device property, it should be checked that the stream is
currently routed to the filter device. It seemed simpler to do it this
way compared to setting up stream move monitoring in filter-apply and
removing the property when the stream moves away from the filter
device.

don't move streams to devices that are going away
Before a device is unlinked, the unlink hook is fired, and it's
possible that a routing module tries to move streams to the unlinked
device in that hook, because it doesn't know that the device is being
unlinked. Of course, the unlinking is obvious when the code is in an
unlink hook callback, but it's possible that some other module does
something in the unlink hook that in turn triggers some other hook,
and it's this second hook where the routing module may get confused.
This patch adds an "unlink_requested" flag that is set before the
unlink hook is fired, and moving streams to a device with that flag
set is prevented.
This patch is motivated by seeing module-device-manager moving a
stream to a sink that was being unlinked. It was a complex case where
an alsa card was changing its profile, while an echo-cancel sink was
connected to the old alsa sink. module-always-sink loaded a null sink
in the middle of the profile change, and after a stream had been
rescued to the null sink, module-device-manager decided to move it
back to the old alsa sink that was being unlinked. That move made no
sense, so I came up with this patch.

echo-cancel: rework move handling

code, this also prevents problems related to trying to move streams

pstream: Support memfd blocks transport
Now that we have the necessary infrastructure to memexport and
mempimport a memfd memblock, extend that support higher up in the
chain with pstreams.
A PA endpoint can now _transparently_ send a memfd memblock to the
other end by simply calling pa_pstream_send_memblock() – provided
the block's memfd pool was earlier registered with the pstream.
If the pipe does not support memfd transfers, we fall back to
sending the block's full data instead of just its reference.
** Further details:
A single pstream connection usually transfers blocks from multiple
pools including the server's srbchannel mempool, the client's
audio data mempool, and the server's global core mempool.
If these mempools are memfd-backed, we now require registering
them with the pstream before sending any blocks they cover. This
is done to minimize fd passing overhead and avoid fd leaks.
Moreover, to support all these pools without hard-coding their
number or nature in the Pulse communication protocol itself, a new
REGISTER_MEMFD_SHMID command is introduced. That command can be
sent _anytime_ during the pstream's lifetime and is used for
creating on demand SHM ID to memfd mappings.

Color global mempools with a special mark. This special marking

To avoid fd leaks, memfd pools are registered with the connection

Such memory regions are then always referenced by their IDs and

Unfortunately this scheme cannot work with global pools since the
registration ID<->memfd mechanism needs to happen for each newly
connected client, and thus the need for a more special handling.
That is, for the pool's fd to be always open :-(
