We are adding the ability for apps to create "storage areas", which are
transparently encrypted directories that can only be opened when the
device is unlocked.
This CL makes the required SELinux policy changes.
First, assign the type "system_userdir_file" to the new top-level
directory /data/storage_area (non-recursively). This is the same type
used by the other top-level directories containing app data, such as
/data/user, and it restricts access to the directory in the desired way.
Second, add new types to represent an app's directory of storage areas,
the storage areas themselves, and their contents:
`storage_area_app_dir`, `storage_area_dir`, and
`storage_area_content_file` respectively.
All are `app_data_file_type`s.
The directory structure and their associated labels is as follows (note
that they also all get the categories of the user+package):
/data/storage_area/userId/pkgName
storage_area_app_dir
/data/storage_area/userId/pkgName/storageAreaName
storage_area_dir
/data/storage_area/userId/pkgName/storageAreaName/myFile.txt
storage_area_content_file
/data/storage_area/userId/pkgName/storageAreaName/mySubDir
storage_area_content_file
These new types allow us to restrict how and which processes interact
with storage areas.
The new type for the contents of storage areas allows us to add new,
desirable restrictions that we cannot add to the more general
`app_data_file` type in order to maintain backwards-compatibility,
e.g., we block apps from executing any files in their storage areas.
Third, allow:
-- vold_prepare_subdirs to create and delete
storage areas on behalf of apps, and assign them the SElinux type
`storage_area_dir`
i.e. create directories
/data/storage_area/$userId/$pkgName/$storageAreaName
-- vold to assign encryption policies to storage area directories
-- installd to create an app's directory of storage areas on app
install, and delete them on app uninstall, and assign them the SElinux
type `storage_area_app_dir`,
i.e. directories /data/storage_area/$userId/$pkgName
We also add a new SELinux type to represent the storage area encryption
keys: `storage_area_key_file`.
The keys are created by vold on storage area creation, and deleted
either by vold if an app calls
the `deleteStorageArea` API function explicitly, or by installd on
app uninstall.
These keys are stored in `/data/misc_ce/$userId/storage_area_keys`,
and only installd and vold have access to them.

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.

This service is used by the audio server for translating
between legacy string KV pairs and AIDL vendor parameters.
It resides on the system_ext partition.
Since it has to be implemented by every SoC vendor, provide
an example implementation. This example service is added
to CF and GSI system_ext. Vendors can use their own names
and policy labels, the only thing that the audio server
depends on is the AIDL interface.
There is no fuzzer for this service because the example
implementation only contains trivial code (interface
methods are stubbed out).

This commit includes two sepolicy changes:
1. change threadnetwork data file to
/data/misc/apexdata/com.android.tethering/threadnetwork
2. use apex_tethering_data_file for files under
/data/misc/apexdata/com.android.tethering
The background is that the Thread daemon (ot_daemon) is merged into the
Tethering mainline module, which means the the Tehtering module now has
code running in both system_server and the standalone unprivileged
ot_daemon process. To prevent ot_daemon from accessing other
apex_system_server_data_file dirs, here use the specific
apex_tethering_data_file for both Tethering and Thread files (A
subdirectory threadnetwork/ will be created for Thread at runtime). This
is similar to apex_art_data_file and apex_virt_data_file.
Note that a file_contexts rule like
```
/data/misc/apexdata/com\.android\.tethering/threadnetwork(/.*)? u:object_r:apex_threadnetwork_data_file:s0
```
won't work because the threadnetwork/ subdir doesn't exist before the
sepolicy rules are evaluated.
