This change renames the non-platform sepolicy files on a DUT from nonplat_* to vendor_*. It also splits the versioned platform sepolicy from vendor_sepolicy.cil to a new file /vendor/etc/selinux/plat_pub_versioned.cil. And only keeps vendor customizations in vendor_sepolicy.cil. Build variable BOARD_SEPOLICY_DIRS is also renamed to BOARD_VENDOR_SEPOLICY_DIRS. Bug: 64240127 Test: boot bullhead/taimen Change-Id: Iea2210c9c8ab30c9ecbcd8146f074e76e90e6943
