It takes a JSON POD description of the PortConfig parameter and sets it
on the node. This can be used to configure the ports of the adapter node
directly.
At the moment, file descriptors may be leaked
due to a malicious/buggy client:
1. If the control messages have been truncated, some file descriptors
may still have been successfully transferred. Currently, seeing
the MSG_CTRUNC bit causes `refill_buffer()` to immediately return
-EPROTO without doing anything with the control messages, which
may contain file descriptors.
2. When there is no truncation, it is still possible that the current
batch of file descriptors causes the total file descriptor count
to go over the maximum number of fds for the given buffer (currently 1024).
In this case, too, `refill_buffer()` immediately returns -EPROTO
without closing the file descriptors that can not be saved.
Fix both of these cases by closing all file descriptors in all
remaining cmsgs when one of the mentioned conditions occur.
Use the lower 32 bits of the object serial as the index. When there is
an overflow, use an invalid index, which will probably result in a
protocol error.
Since 01c6fd0a88 the
minimum required meson version is 0.59.0, and since
meson 0.58.0, `get_variable()` on a dependency object
accepts a positional argument. The "type" of variable
(internal, pkgconfig, etc.) in that case does not need
to be specified explicitly.
Because otherwise just looking at the rest of the output and seeing the
thread being set to priority 20 instead of the value that's set in the
config file may look a bit confusing.
I don't think PipeWire currently has a way to temporarily alias
module-rtkit to module-rt though, so right now this would break realtime
scheduling for people with modified configs that use module-rtkit.
Try regular realtime scheduling using sched_setscheduler (or the
pthreads equivalent) before falling back to rtkit. This is how it rtkit
was to be used, and it removes one configuration step from using
PipeWire for pro audio. The implementation should also work on FreeBSD
when PipeWire is run as root since to my knowledge there's currently no
way for normal users to use realtime scheduling on FreeBSD, but this has
not been tested.
This commit also fixes a memory leak because `impl->props` was never
freed again.
Don't use max_quantum as the upper quantum limit, this is now scaled
with the rate. Use quantum_limit instead. We don't really care about the
max_quantum anymore so get rid of the field.
Firstly, separate the message dropping logic into
its own `drop_from_out_queue()` function.
Secondly, do not check earlier messages if the NEW
event for a particular object has been reached while
processing a REMOVE event for that object.
Thirdly, if - while processing a REMOVE event -
the corresponding NEW event is found and dropped,
drop the REMOVE event as well.
See #1840
Parse the quantum_limit parameters and use this to scale the buffers so
that they can contain the maximum allowed samples instead of the
hardcoded 8192 value.
See #1931
Also scale the max_quantum with the selected rate. Add a new
quantum_limit property that is the upper limit of the quantum regardless
of the sample rate, this is usually the allocated buffer size.
See #1931
Based on patch from Barnabás Pőcze <pobrn@protonmail.com>
Instead of trying to keep track of the missing bytes ourselves, use the
simple tlength - avail - requested formula to request more bytes from
the client.
Fixes#1981
Extend the server.address property so that you can also specify
an object per server. Add support for configuring some aspects of the
server such as max-clients and backlog.
Most importantly, the pipewire client.access can be configured per
server.
See #1960
If not otherwise set, the media.name will be the name used when
pw_stream_new(), which is the same for all loopback streams.
This makes the session manager restore the same volume for all
loopback streams.
Do something more clever and use the node.name + suffix to make
the name unique per stream if no media.name was given.
