# sepolicy is now divided into multiple portions:
# public - policy exported on which non-platform policy developers may write
#   additional policy.  types and attributes are versioned and included in
#   delivered non-platform policy, which is to be combined with platform policy.
# private - platform-only policy required for platform functionality but which
#  is not exported to vendor policy developers and as such may not be assumed
#  to exist.
# vendor - vendor-only policy required for vendor functionality. This policy can
#  reference the public policy but cannot reference the private policy. This
#  policy is for components which are produced from the core/non-vendor tree and
#  placed into a vendor partition.
# mapping - This contains policy statements which map the attributes
#  exposed in the public policy of previous versions to the concrete types used
#  in this policy to ensure that policy targeting attributes from public
#  policy from an older platform version continues to work.

# build process for device:
# 1) convert policies to CIL:
#    - private + public platform policy to CIL
#    - mapping file to CIL (should already be in CIL form)
#    - non-platform public policy to CIL
#    - 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.
#    - compile output binary policy file

# The file_contexts.bin is built in the following way:
# 1. Collect all file_contexts files in THIS repository and process them with
#    m4 into a tmp file called file_contexts.local.tmp.
# 2. Collect all device specific file_contexts files and process them with m4
#    into a tmp file called file_contexts.device.tmp.
# 3. Run checkfc -e (allow no device fc entries ie empty) and fc_sort on
#    file_contexts.device.tmp and output to file_contexts.device.sorted.tmp.
# 4. Concatenate file_contexts.local.tmp and file_contexts.device.tmp into
#    file_contexts.concat.tmp.
# 5. Run checkfc and sefcontext_compile on file_contexts.concat.tmp to produce
#    file_contexts.bin.
#
#  Note: That a newline file is placed between each file_context file found to
#        ensure a proper build when an fc file is missing an ending newline.
