`IN_IGNORED` event is sent whenever the watch is removed,
which includes when the entity is deleted among other things,
so watch that instead of the more specific `IN_DELETE_SELF`.
(cherry picked from commit 04b8a0c215)
When we receive a message with fds and we are at the end of the
buffer, we will call clear_buffer, which moves the next fds over the
fds of this message before we copy the fds into the message. This
results in the fd being leaked and the message using the fd of the next
message instead.
Avoid this by first copying the fds into the message and then move the
new ones over the old ones.
This fixes some wrong fds being used by clients.
Instead of aligning the buffers to 16 bytes, use the CPU max_align
value (32 on intel).
Move the mix function from a static global variable to a per client
member because this could change per client.
When we drop the first buffer to avoid timestamp problems, queue it
again in the driver or else we will not be able to dequeue is again
later and we will be running with a buffer less.
`pw_link_info::error` was previously not cleared when a link was destroyed,
leading to a memory leak if an error message had been set. For example,
if format negotiation fails, and as a result the link is destroyed.
Claim that call waiting notifications are supported.
Required for some devices (e.g. Soundcore Motion 300),
as they stop sending commands if the reply to CCWA is not OK.
When we emit the RequestProcess event from an exported node, don't
send the RequestProcess command to ourselves but let the server
decide where to send it to.
Input driver streams don't need their process callback called before
starting the graph, they will get their process callback called at the
end of the graph cycle. We were doing this for the rt case fine but not
for the non-rt case.
Make a property to pass a custom function pointer to create threads
instead of pthread_create.
Use this in jack instead of bypassing the thread utils create function,
which gives the wrong thread rt priority with rtkit.
Fixes#4099
Use dynamic pod builder so that we can also build complex formats.
Make sure we zero the format before we parse it or else we end up with
potentially uninitialized values.
When ENUM_FRAMESIZES or VIDIOC_ENUM_FRAMEINTERVALS return EINVAL for the
first index, make a dummy result and continue with that. This will
trigger an intersect withe filter so that we end up with something valid
instead of nothing.
Handle 0 framerates without crashing.

Some complex camera pipelines, like the IPU6 can involve many /dev/video#
nodes (32 in the IPU6 case) and the current size of 128 chars is not enough
to hold all /dev/video# nodes in this cases causing SPA_KEY_DEVICE_DEVIDS
to get truncated, which in turn breaks the filtering of V4L2 devices which
are used by a libcamera driven camera in wireplumber.
Fix this by increasing the size of devices_str[] to 256.
This fixes wireplumber adding a bunch of non-function V4L2 video sources,
e.g. before this "wpctl status" outputs the following video sources:
Video
├─ Devices:
...
├─ Sources:
│ 90. ov2740
│ * 115. ipu6 (V4L2)
...
│ 135. ipu6 (V4L2)
│
├─ Filters:
After this fix the output is:
Video
├─ Devices:
...
├─ Sources:
│ * 92. ov2740
│
├─ Filters:

We have various modules that set the priority higher than the dummy and
freewheel driver (ffado, netjack,...). This makes it impossible to use
the freewheel driver on them.
Use a memstream to collect the arguments so that it can dynamically
allocate as much memory as necessary.
Use a dynamic pod builder to construct the pods so that they can be of
arbitrary size.
Fixes#4166
Only set use the graph rate and duration when the ffado.sample-rate
and ffado.period-size properties are set to 0. Othersize use the
configure values.
Without this patch, it would just ignore the settings and always use the
graph rate.
Change the GenericFd data type to SyncObj. It's probably better to
explicitly state the data type than to make something generic. Otherwise
we would need to transfer the specific fd type somewhere else and there
is no room for that in the buffer and the the metadata is not a good idea
either because it can be modified and corrupted at runtime.
Add the SyncTimeline metadata. This contains 2 points on two timelines
(SyncObj datas in the buffer). The buffer can be accessed when the
acquire_point is signaled on the timeline and when the buffer
can be released, the release_point on the timeline should be signaled.
Add a SPA_PARAM_BUFFERS_metaType in the Buffers object. This contains a
bitmask of the mandatory metadata items that should be included on a
buffer when using this Buffers param.
Make the buffer allocation logic skip over the Buffers params that
require unavailable metadata.
This can be used to, for example, enforce specific metadata to describe
extra buffer memory (such as the meaning of generic file descriptors).
One such use is the explicit sync, where an extra buffer data is needed
for the sync fd along with metadata that contains the sync_point.
Parse the metas right after we fixate the params and collec them in the
metas array. We don't have to loop twice and then we can simply pass the
prepared metas to alloc_buffers.
In case there are multiple Buffers params, take the first valid one and
ignore invalid ones.
In order to show metadata changes when monitoring, a sync must be
triggered just like it is done for other objects, to make sure that
`dump_objects()` is called some time later and the changed metadata
objects are shown.
Otherwise metadata changes would never be displayed unless there
was a change to a different type of object, whose event handlers
do trigger a sync.
Fixes#4053
Avoid freeing the old io Position area before the data loop has managed
to get a pointer to it. Queue a free operation that will be executed
from the main loop after the data loop has the io area.
Fixes a crash when stressing jack clients to switch between drivers.
We are not allowed to call free_link from the data thread because it
does free() and some pw_mem calls which should only be called from the
main thread.
To solve this, pause the core, queue a free_link operation on the data
thread, which will be scheduled after the previous remove_link operation
completes, free the link and then resume the core. Blocking and resuming
the core is necessary because we can't block for completion of the
invoke calls (the jack method is not allowed to block) and we must
ensure that nothing can happen with the memory (like reuse the mem_id)
before we have cleaned it up.
Fixes a crash in jack with create/destroy link stress.
When for some reason we don't manage to transfer data from the source
or to the sink (timeout, scheduling problems..), try to do it when we
get a timeout to avoid xruns.
