Steps taken to produce the mapping files:
0. Add 33.0 prebuilts to prebuilts/api/33.0/.
1. Add the following Android.bp modules.
33.0.board.compat.map
33.0.board.compat.cil
33.0.board.ignore.map
plat_33.0.cil
system_ext_33.0.cil
product_33.0.cil
33.0.ignore.cil
system_ext_33.0.ignore.cil
product_33.0.ignore.cil
33.0.compat.cil
system_ext_33.0.compat.cil
2. Touch the following three files.
private/compat/33.0/33.0.cil
private/compat/33.0/33.0.compat.cil
private/compat/33.0/33.0.ignore.cil
3. Add 33.0 to PLATFORM_SEPOLICY_COMPAT_VERSIONS on
build/make/core/config.mk. Note that we don't update
sepolicy_major_vers to 33, but just update compat versions.
4. Run the following command.
$ source build/make/rbesetup.sh && lunch aosp_arm64-userdebug
$ m sepolicy_generate_compat
$ sepolicy_generate_compat --branch=tm-dev \
--build latest --target-version 33.0 \
--latest-version 32.0
This change also enables treble_sepolicy_tests_33.0 and installs
33.0.cil mapping file onto the device.

se_build_files is a replacement for se_filegroup module. se_build_files
can be used with the normal Soong convention ":module_name{.tag}" by
implementing android.OutputFileProducer. It's better than implementing
ad-hoc logics across various modules, which is the case for se_filegroup
module.

To generate compat files, we need the following files.
- base_plat_sepolicy: to get all types
- base_plat_pub_policy.cil: to get public types
- {ver}_plat_sepolicy: to get old types
This creates a new dist goal, base-sepolicy-files-for-mapping, to
conveniently generate and gather desired files under out/dist.

When we compile sepolicy files into a cil file, we first gather all
sepolicy files to create a conf file, and then convert the conf file to
a cil file with checkpolicy. The problem is that checkpolicy is
sensitive to the input order; the conf file should contain statements in
a specific order: classes, initial_sid, access vectors, macros, mls,
etc.
This restriction has made Android.bp migration difficult, and we had to
create a magical module called "se_build_files" to correctly include
source files in the designated order. It works, but significant
readability problem has happened. For example, when we write
":se_build_files{.system_ext_public}", how can we easily figure out that
the tag actually includes plat public + system_ext public + reqd mask,
without taking a look at the build system code?
This change refactors the se_build_files module and se_policy_conf
module, so we can easily see the desginated files for each module, just
like we did in the Android.mk. se_policy_conf module now stably sorts
source files in an order which will make checkpolicy happy.
se_build_files module is also refactored, so one tag can represent
exactly one set of policy files, rather than doing magical works behind
the scene. For example, system_ext public policy module is changed from:
se_policy_conf {
name: "system_ext_pub_policy.conf",
// se_build_files automatically adds plat public and reqd mask
srcs: [":se_build_files{.system_ext_public}"],
}
to:
se_policy_conf {
name: "system_ext_pub_policy.conf",
// se_policy_conf automatically sorts the input files
srcs: [
":se_build_files{.plat_public}",
":se_build_files{.system_ext_public}",
":se_build_files{.reqd_mask}",
],
}

Bug: 207815515
Test: build
Change-Id: I98d5972221a8e77f3c45fc48ff50bb2b8eb94275
Steps taken to produce the mapping files:
1. Add prebuilts/api/32.0/plat_pub_versioned.cil from the
/vendor/etc/selinux/plat_pub_versioned.cil file built on sc-v2-dev with
lunch target aosp_arm64-eng. Add prebuilts/api/32.0/vendor_sepolicy.cil
as an empty file.
When adding plat_pub_versioned.cil, leave only type and typeattribute
statements, removing the other statements: allow, neverallow, role, etc.
2. Add new file private/compat/32.0/32.0.cil by doing the following:
- copy /system/etc/selinux/mapping/32.0.cil from sc-v2-dev
aosp_arm64-eng device to private/compat/32.0/32.0.cil
- remove all attribute declaration statement (typeattribute ...) and
sort lines alphabetically
- some selinux types were added/renamed/deleted w.r.t 32 sepolicy.
Find all such types using treble_sepolicy_tests_32.0 test.
- for all these types figure out where to map them by looking at
31.0.[ignore.]cil files and add approprite entries to 32.0.[ignore.]cil.
This change also enables treble_sepolicy_tests_32.0 and installs
32.0.cil mapping file onto the device.
