This commit adds fake 31.0 prebuilt. The prebuilt is based on AOSP policy, but slightly modified so the set of types and attributes is a subset of real 31.0 prebuilt (sc-dev policy). Steps taken to make the fake prebuilt: 1) build plat_sepolicy.cil both on AOSP and sc-dev, with lunch target aosp_arm64-eng. 2) diff both outputs to find out which types and attributes don't exist. 3) remove all relevant files and statements. As a result, the following types are removed. artd artd_exec artd_service power_stats_service transformer_service virtualizationservice virtualizationservice_data_file virtualizationservice_exec Bug: 189161483 Test: N/A, will do after adding 31.0 mapping files.

# Below are strong assertion that only init, system_server and tzdatacheck
|
|
# can modify the /data time zone rules directories. This is to make it very
|
|
# clear that only these domains should modify the actual time zone rules data.
|
|
# The tzdatacheck binary itself may be executed by shell for tests but it must
|
|
# not be able to modify the real rules.
|
|
# If other users / binaries could modify time zone rules on device this might
|
|
# have negative implications for users (who may get incorrect local times)
|
|
# or break assumptions made / invalidate data held by the components actually
|
|
# responsible for updating time zone rules.
