Introduce a generic netlink multicast event to report binder transaction failures to userspace. This allows subscribers to monitor these events and take appropriate actions, such as stopping a misbehaving application that is spamming a service with huge amount of transactions. The multicast event contains full details of the failed transactions, including the sender/target PIDs, payload size and specific error code. This interface is defined using a YAML spec, from which the UAPI and kernel headers and source are auto-generated.

Binder is used in Android for both communication between processes,
|
|
and remote method invocation.
|
|
|
|
This means one Android process can call a method/routine in another
|
|
Android process, using Binder to identify, invoke and pass arguments
|
|
between said processes.

Binderfs is a pseudo-filesystem for the Android Binder IPC driver
|
|
which can be mounted per-ipc namespace allowing to run multiple
|
|
instances of Android.
|
|
Each binderfs mount initially only contains a binder-control device.
|
|
It can be used to dynamically allocate new binder IPC devices via
|
|
ioctls.

Default value for the binder.devices parameter.
|
|
|
|
The binder.devices parameter is a comma-separated list of strings
|
|
that specifies the names of the binder device nodes that will be
|
|
created. Each binder device has its own context manager, and is
|
|
therefore logically separated from the other devices.

This feature builds the binder alloc KUnit tests.
|
|
|
|
Each test case runs using a pared-down binder_alloc struct and
|
|
test-specific freelist, which allows this KUnit module to be loaded
|
|
for testing without interfering with a running system.
