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.

An APK installing with .idsig gets fs-verity enabled during the package
install. As a step of package install, a package verifier may inspect
the APK. A v4 signature check requires calling FS_IOC_MEASURE_VERITY.
This change gives priv_app the permission (which appdomain already has).

Since Android S, we started to enforce the debugfs restrictions. However,
GSI had it turned off (PRODUCT_SET_DEBUGFS_RESTRICTIONS := false) in order
to support pre-S vendor images.
This has an undesirable side effect that the restriction is turned off even
for S+ vendors.
This CL fixes it by
1) re-enabling the restriction for GSI and
2) manually adding the debugfs permissions only to the compat cil for the
pre-S (29 and 30) vendors, effectively turning the restriction off for
them.
