fb69c8e64f netlink_route_socket: add new nlmsg_readpriv perm
Used when mapping RTM_GETLINK messages to this new permission.

Users of netlink_route_sockets that do not use the net_domain()
macro will need to grant this permission as needed. Compatibility
with older vendor images is preserved by granting all vendor domains
access to this new permission in *.compat.cil files.

1019870fba Mark mediacodec_2{6,7,8} as hal_omx_server
The commit 7baf725ea6 broke OMX on O/O-MR1(/P?) vendors.
Previous to this commit, all OMX codecs had to use "mediacodec" type,
after this commit, omx codecs just had to get hal_omx_server attribute.
This commit left to the vendor the charge of adding "hal_omx_server"
attribute to mediacodec.

However this can't work on non-Q vendors.

On P vendor, versioned_plat_pub contains the appdomain <=> mediacodec
allows, so OMX isn't technically broken on those devices.
But to ensure it won't break in the future, mark 28's mediacodec as
hal_omx_server as well

This fixes broken OMX decoding on O/O-MR1 vendors, failing with the
following denial:

04d2392c35 Don't use apexd when TARGET_FLATTEN_APEX == true
/system/apex/com.android.runtime is labeled as runtime_apex_dir
and init is allowed to mount on it.

When TARGET_FLATTEN_APEX is true (= ro.apex.updatable is unset or set to
false), apexd is not used to activate the built-in flattened APEXes.
Init simply bind-mounts /system/apex to /apex.

However, there is a special case here. The runtime APEX is installed as
either /system/apex/com.android.runtime.debug or
/system/apex/com.android.runtime.release, whereas it should be activated
on /apex/com.android.runtime - without the .debug or .release suffix.
To handle that case, the build system creates an empty directory
/system/apex/com.android.runtime and the .debug or .release directory
is bind-mounted to the empty directory by init at runtime.

ecc7e8cacb Move /sbin/charger to /system/bin/charger.
With the CLs in the same topic, it's being built as a dynamically linked
executable. And this applies to normal boot (including charger mode) and
recovery mode both.

/system/bin/charger under normal boot will be labeled as charger_exec,
which has the attribute of system_file_type.

The file in recovery image will still be labeled as rootfs. So we keep
the domain_trans rule for rootfs file, but allowing for recovery mode
only.

1bbda7e662 Initial sepolicy for app_zygote.
The application zygote is a new sort of zygote process that is a
child of the regular zygote. Each application zygote is tied to the
application for which it's launched. Once it's started, it will
pre-load some of the code for that specific application, much like
the regular zygote does for framework code.

Once the application zygote is up and running, it can spawn
isolated service processes that run in the isolated_app domain. These
services can then benefit from already having the relevant
application code and data pre-loaded.

The policy is largely the same as the webview_zygote domain,
however there are a few crucial points where the policy is different.

1) The app_zygote runs under the UID of the application that spawned
   it.
2) During app_zygote launch, it will call a callback that is
   controlled by the application, that allows the application to
   pre-load code and data that it thinks is relevant.

Especially point 2 is imporant: it means that untrusted code can run
in the app_zygote context. This context is severely limited, and the
main concern is around the setgid/setuid capabilities. Those conerns
are mitigated by installing a seccomp filter that only allows
setgid/setuid to be called in a safe range.

Bug: 111434506
Test: app_zygote can start and fork children without denials.

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.

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.
