# Do not permit access from apps which host arbitrary code to HwBinder services,

# The two main reasons for this are:
# 1. HwBinder servers do not perform client authentication because HIDL
# currently does not expose caller UID information and, even if it did, many
# HwBinder services either operate at a level below that of apps (e.g., HALs)
# or must not rely on app identity for authorization. Thus, to be safe, the
# default assumption is that every HwBinder service treats all its clients as
# equally authorized to perform operations offered by the service.
# 2. HAL servers (a subset of HwBinder services) contain code with higher
# incidence rate of security issues than system/core components and have
# access to lower layes of the stack (all the way down to hardware) thus
# increasing opportunities for bypassing the Android security model.
#
# Safe services include:
# - 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 safe because they do not pose risks
# associated with reason #2 above.
# - 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.
