Add a new module parameter 'devices', that can be used to specify the names of the binder device nodes we want to populate in /dev. Each device node has its own context manager, and is therefore logically separated from all the other device nodes. The config option CONFIG_ANDROID_BINDER_DEVICES can be used to set the default value of the parameter. This approach was favored over using IPC namespaces, mostly because we require a single process to be a part of multiple binder contexts, which seemed harder to achieve with namespaces.

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.

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.

The Binder API has been changed to support both 32 and 64bit
|
|
applications in a mixed environment.
|
|
|
|
Enable this to support an old 32-bit Android user-space (v4.4 and
|
|
earlier).
|
|
|
|
Note that enabling this will break newer Android user-space.
