Steps taken to produce the mapping files: 1. Add prebuilts/api/28.0/[plat_pub_versioned.cil|vendor_sepolicy.cil] from the /vendor/etc/selinux/[plat_pub_versioned.cil|vendor_sepolicy.cil] files built on pi-dev with lunch target aosp_arm64-eng 2. Add new file private/compat/28.0/28.0.cil by doing the following: - copy /system/etc/selinux/mapping/28.0.cil from pi-dev aosp_arm64-eng device to private/compat/28.0/28.0.cil - remove all attribute declaration statement (typeattribute ...) and sort lines alphabetically - some selinux types were added/renamed/deleted w.r.t 28 sepolicy. Find all such types using treble_sepolicy_tests_28.0 test. - for all these types figure out where to map them by looking at 27.0.[ignore.]cil files and add approprite entries to 28.0.[ignore.]cil. This change also enables treble_sepolicy_tests_28.0 and install 28.0.cil mapping onto the device. Bug: 72458734 Test: m selinux_policy Change-Id: I90e17c0b43af436da4b62c16179c198b5c74002c
