-# System and vendor domains for BoringSSL self test binaries.
-#
-# For FIPS compliance, all processes linked against libcrypto perform a startup
-# self test which computes a hash of the BoringSSL Crypto Module (BCM) and, at least once
-# per device boot, also run a series of Known Answer Tests (KAT) to verify functionality.
-#
-# The KATs are expensive, and to ensure they are run as few times as possible, they
-# are skipped if a marker file exists in /dev/boringssl/selftest whose name is
-# the hash of the BCM that was computed earlier.  The files are zero length and their contents
-# should never be read or written.  To avoid giving arbitrary processes access to /dev/boringssl
-# to create these marker files, there are dedicated self test binaries which this policy
-# gives access to and which are run during early-init.
-#
-# Due to build skew, the version of libcrypto in /vendor may have a different hash than
-# the system one.  To cater for this there are vendor variants of the self test binaries
-# which also have permission to write to the same files in /dev/boringssl.  In the case where
-# vendor and system libcrypto have the same hash, there will be a race to create the file,
-# but this is harmless.
-#
-# If the self tests fail, then the device should reboot into firmware and for this reason
-# the system boringssl_self_test domain needs to be in coredomain.  As vendor domains
-# are not allowed in coredomain, this means that the vendor self tests cannot trigger a
-# reboot.  However every binary linked against the vendor libcrypto will abort on startup,

-### This file defines the rules shared by all untrusted app domains except

-### Apps are labeled based on mac_permissions.xml (maps signer and
-### optionally package name to seinfo value) and seapp_contexts (maps UID
-### and optionally seinfo value to domain for process and type for data
-### directory).  The untrusted_app_all attribute is assigned to all default

-### that are not signed by the platform key.  To move

-### mac_permissions.xml and assign it one of the pre-existing seinfo values
-### or define and use a new seinfo value in both mac_permissions.xml and
