Track system_server->apex_art_data_file denial.
The denial occurs when system_server dynamically loads AOT artifacts at
runtime.
Sample message:
type=1400 audit(0.0:4): avc: denied { execute } for comm="system_server" path="/data/misc/apexdata/com.android.art/dalvik-cache/arm64/system@framework@com.android.location.provider.jar@classes.odex" dev="dm-37" ino=296 scontext=u:r:system_server:s0 tcontext=u:object_r:apex_art_data_file:s0 tclass=file permissive=0
Currently, system_server is only allowed to load AOT artifacts at startup. odrefresh compiles jars in SYSTEMSERVERCLASSPATH, which are supposed to be loaded by system_server at startup. However, com.android.location.provider is a special case that is not only loaded at startup, but also loaded dynamically as a shared library, causing the denial.
Therefore, this denial is currently expected. We need to compile com.android.location.provider so that its AOT artifacts can be picked up at system_server startup, but we cannot allow the artifacts to be loaded dynamically for now because further discussion about its security implications is needed. We will find a long term solution to this, tracked by b/194054685.
