4fde9ec7b3 Add heapprofd selinux config.
This does not actually grant any permissions but just adds the
necessary boilerplate for a new service.

e8b33c3139 Add type for /system/bin/tcpdump.
We add this type with the intent to expose /system/bin/tcpdump to
vendor on userdebug devices only.

Bug: 111243627
Test: device boots /system/bin/tcpdump correctly labeled as
tcpdump_exec, can browse internet, turn wifi on/off

3639f57960 Allow system_server to read vendor_file
Input device configuration files .idc, .kl that are placed in /vendor
are currently not accessible.
Allow the read access here.

Bug: 112880217
Test: move .idc and .kl files from /system to /vendor, then observe
logcat. With this patch, avc denials disappear.

438684b39f Only maintain maps between current and previous selinux versions.
New maintenance scheme for mapping files:
Say, V is the current SELinux platform version, then at any point in time we
only maintain (V->V-1) mapping. (V->V-n) map is constructed from top (V->V-n+1)
and bottom (V-n+1->V-n) without changes to previously maintained mapping files.

Caveats:
- 26.0.cil doesn't technically represent 27.0->26.0 map, but rather
current->26.0. We'll fully migrate to the scheme with future releases.

Bug: 67510052
Test: adding new public type only requires changing the latest compat map

ff1c765ff2 Label /system/usr/share/zoneinfo differently
/system/usr/share/zoneinfo is currently labeled zoneinfo_data_file,
a label shared with /data/misc/zoneinfo. However, each of these
directory locations has different security characteristics. In
particular, the files in /system/usr/share/zoneinfo must never be
writable, whereas /data/misc/zoneinfo may be written to by system_server.
Reusing the same label hides these different security characteristics.

Create a separate label for /system/usr/share/zoneinfo.

Test: Device boots and no obvious problems.

23c9d91b46 Start partitioning off privapp_data_file from app_data_file
Currently, both untrusted apps and priv-apps use the SELinux file label
"app_data_file" for files in their /data/data directory. This is
problematic, as we really want different rules for such files. For
example, we may want to allow untrusted apps to load executable code
from priv-app directories, but disallow untrusted apps from loading
executable code from their own home directories.

This change adds a new file type "privapp_data_file". For compatibility,
we adjust the policy to support access privapp_data_files almost
everywhere we were previously granting access to app_data_files
(adbd and run-as being exceptions). Additional future tightening is
possible here by removing some of these newly added rules.

This label will start getting used in a followup change to
system/sepolicy/private/seapp_contexts, similar to:

  -user=_app isPrivApp=true domain=priv_app type=app_data_file levelFrom=user
  +user=_app isPrivApp=true domain=priv_app type=privapp_data_file levelFrom=user

For now, this newly introduced label has no usage, so this change
is essentially a no-op.

Test: Factory reset and boot - no problems on fresh install.
Test: Upgrade to new version and test. No compatibility problems on
      filesystem upgrade.

1fa9634896 Add mapping files for 28.0.[ignore.]cil
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.
