# Following is the hwservices that are explicitly not marked with protected_hwservice.
# These are directly accessible from untrusted apps.
# - same process services: because they by definition run in the process
#   of the client and thus have the same access as the client domain in which
#   the process runs
# - coredomain_hwservice: are considered safer than ordinary hwservices which
#   are from vendor partition
# - hal_configstore_ISurfaceFlingerConfigs:  becuase it has specifically been
#   designed for use by any domain.
# - hal_graphics_allocator_hwservice: because these operations are also offered
#   by surfaceflinger Binder service, which apps are permitted to access
# - hal_omx_hwservice: because this is a HwBinder version of the mediacodec
#   Binder service which apps were permitted to access.
# - hal_codec2_hwservice: because this is a newer version of hal_omx_hwservice.
# - hal_drm_hwservice: versions > API 29 are designed specifically with
#   untrusted app access in mind.
