EdgeTpu DBA service calls edgetpu_app_service's UserIsAuthorized API in order to know whether its clients are authorized to use priviledge features, see code: https://source.corp.google.com/android-internal/vendor/google/darwinn2/dba/service/edgetpu_device.cpp;l=73;rcl=1c57b54efe12cdb408cb21a992155a04d151e3ce It looks like the SELinux rule is missing today. Though I'm not sure why DBA service doesn't crash today. Bug: 237103652 Change-Id: I8c5da7413eb6f9efc527c9f9f1d1242f0cb4dea8
