Ideally, public should only contain APIs (types / attributes) for
vendor. The other statements like allow/neverallow/typeattributes are
regarded as implementation detail for platform and should be in private.

This new property is to set an apex name when input configuration files
are bundled in an apex.
libinput checks the new sysprop when loading input configuration.
This removes hard-coded apex name (com.android.input.config).

The default policy for the "lockdown" access vector on Android was
introduced in commit bcfca1a6. While the "confidentiality" permission
was granted to all processes, the "integrity" was marked as
neverallowed.
Upstream, the support for that access vector was removed from kernel
5.16 onwards.
It was found that the "integrity" permission either does not apply to
Android or duplicates other access control (e.g., capabilities
sys_admin).
Instead of simply removing the neverallow rule, the access is granted to
all processes. This will prevent the proliferation of references to this
access vector in vendors' policies and ultimately facilitate its
removal.

1, /metadata/aconfig is the directory that stores aconfig storage
related protobuf files and flag value files boot copy. Grant read
access to everybody. But limit the write access only to init and
aconfig storage service process (to be created later)
2, /metadata/aconfig/flags is the sub directory that stores persistent
aconfig value files.Initially set it up to be accessible by
system_server process only . When aconfig storage service process is
created, will add another permission to storage service process.
Context to why we are hosting flag data on /metadata partition:
Android is adopting trunk stable workflow, flagging and A/B testing is
essential to every platform component. We need some place to host the
flag that are accessible to system processes that starts before /data
partition becomes available.
In addition, there has been a long discussion regarding utilizing
/metadata partition for some process data, another example is mainline
modules, we are trying to make them to be able to be mounted earlier,
but cannot due to /data availability.

Grant bootanimation all read permissions on oem using
r_dir_file macro instead of specifying individual permissions.
This prevents failure to read the bootanimation on oem if
partition has been remounted.
After remount, bootanimation will log violation for the
/oem/media directory when reading an existing file (boot animation can
is still played).
avc: denied { read } for pid=2820 comm="bootanimation" name="media"
dev="sda75" ino=152 scontext=u:r:bootanim:s0
tcontext=u:object_r:oemfs:s0 tclass=dir permissive=0
After remount, if modifying/adding file in /oem/media directory,
bootanimation will fail to read the bootanimation zip, now with
violation:
avc: denied { read } for pid=2838 comm="bootanimation" name="media"
dev="dm-8" ino=70 scontext=u:r:bootanim:s0 tcontext=u:object_r:oemfs:s0
tclass=dir permissive=0
