# - non-platform public + private policy to CIL
# 2) attributize policy
# - run script which takes non-platform public and non-platform combined
# private + public policy and produces attributized and versioned
# non-platform policy
# 3) combine policy files
# - combine mapping, platform and non-platform policy.

# vendor policies are separately built. More specifically,
#
# - Platform policy files needed to build vendor policies, such as plat_policy,
# plat_mapping_cil, plat_pub_policy, reqd_policy_mask, are built from the
# prebuilts (copy of platform policy files of version BOARD_SEPOLICY_VERS).

# sepolicy_neverallows_vendor checks vendor policies.
#
# - neverallow checks are turned off while compiling precompiled_sepolicy module
# and sepolicy module.
#
# - Vendor policies are not checked on the compat test (compat.mk).
#
# In such scenario, we can grab platform policy files from the prebuilts/api
# directory. But we need more than that: prebuilts of system_ext, product,
# system/sepolicy/reqd_mask, and system/sepolicy/vendor. The following variables
# are introduced to specify such prebuilts.

# - BOARD_REQD_MASK_POLICY (prebuilt of system/sepolicy/reqd_mask)

# - BOARD_SYSTEM_EXT_PRIVATE_PREBUILT_DIRS (prebuilt of system_ext private)
# - BOARD_PRODUCT_PUBLIC_PREBUILT_DIRS (prebuilt of product public)
# - BOARD_PRODUCT_PRIVATE_PREBUILT_DIRS (prebuilt of product private)
#
# Vendors are responsible for copying policy files from the old version of the
# source tree as prebuilts, and for setting BOARD_*_POLICY variables so they can
# be used to build vendor policies. See prebuilt_policy.mk for more details.
#
# To support both mixed build and normal build, platform policy files are
# indirectly referred by {partition}_{public|private}_policy_$(ver) variables
# when building vendor policies. See vendor_sepolicy.cil and odm_sepolicy.cil
# for more details.
