# TODO(b/34274385): Remove this once Telphony HAL is guaranteed to not be run in passthrough mode
# What's going on here is that Telephony HAL is talking over sockets to ims daemon, which is
# permitted. However, those rules target hal_telephony rather than hal_telephony_server and thus
# are also granted to all clients of Telephony HAL (e.g., radio daemon) which are core
# components, and socket communications between system components and vendor components are not
# permted.
# Once we switch full Treble devices to binderized only mode, this issue will disappear.
