The report_off_body permission of the "keystore2" class only guarded the
Binder API IKeystoreMaintenance#onDeviceOffBody() served by keystore2.
That API is being removed because it is unused
(https://r.android.com/2974277). Therefore, stop granting the
report_off_body permission.
Don't actually remove the permission from private/access_vectors. That
would break the build because it's referenced by rules in prebuilts/.
However, document the access vectors that are known to be unused.

This patch:
* allows for heap and perf profiling of all processes on the system
(minus undumpable and otherwise incompatible domains). For apps, the
rest of the platform will still perform checks based on
profileable/debuggable manifest flags. For native processes, the
profilers will check that the process runs as an allowlisted UID.
* allows for all apps (=appdomain) to act as perfetto tracing data
writers (=perfetto_producer) for the ART java heap graph plugin
(perfetto_hprof).
* allows for system_server to act a perfetto_producer for java heap
graphs.

Access to files in sysfs_net allows bypassing permissions gated
information. Also remove permission for priv_app
to call SIOCGIFHWADDR, which is also a permissions bypass.
Examples:
- Information in /sys/class/net/wlan0/statistics/rx_packets should
be gated by PACKAGE_USAGE_STATS.
- Information in /sys/class/net/wlan0/address should be gated by
LOCAL_MAC_ADDRESS or READ_PRIVILEGED_PHONE_STATE.

This is a follow-up to r.android.com/1542764.
1. In order to allow priv_app to
stat(/data/misc/perfetto-traces/bugreport/*) we need
also the `search` permission to traverse the parent
directory /data/misc/perfetto-traces.
2. Allow shell to read the new bugreport/ directory.
shell can read bugreports anyways and this is needed
for CTS tests.

Feature description: if a background trace is happening at the
time dumpstate is invoked, the tracing daemon will snapshot
the trace into a fixed path (/data/misc/perfetto-traces/bugreport/).
Dumpstate will attach the trace, if present, to the bugreport.
From a SELinux viewpoint this involves the following permissions:
- Allow dumpstate to exec+trans perfetto --save-for-bugreport
(this will just send an IPC to traced, which will save the trace).
- Allow dumpstate to list, read and unlink the trace file.
- Create a dedicated label for bugreport traces, to prevent that
dumpstate gets access to other traces not meant for bug reporting.
Note that this does NOT allow dumpstate to serialze arbitary traces.
Traces must be marked as "eligible for bugreport" upfront in the
trace config (which is not under dumpstate control), by
setting bugreport_score > 0.
Design doc: go/perfetto-betterbug
Bug: 170334305
Test: manual:
1. start a perfetto trace with bugreport_score > 0
2. adb shell dumpstate
3. check that the bugreport zip contains the trace

During staged installation, we no longer create duplicate sessions for
verification purpose. Instead, we send the original files in
/data/app-staging folder to package verifiers for verification. That
means, Phonesky needs access to /data/app-staging folder to be able to
verify the apks inside it.

the cgroups v2 uid/gid hierarchy will replace cgroup for all sepolicy
rules. For this reason, old rules have to be duplicated to cgroup_v2,
plus some rules must be added to allow the ownership change for cgroup

For ContentProvider case, private app can not access system app data. So we added this rule to solve this issue.

Test: <Before modifying the rules, when the private app accesses files in the app-specific directory shared by the system app through the ContentProvider, the system will report selinux permission issue.
After modifying the rules and compiling the new version, the private app can access the files in the app-specific directory shared by the system app through the ContentProvider without any permission issues.>

This is a domain for the MediaProvider mainline module. The
MediaProvider process is responsible for managing external storage, and
as such should be able to have full read/write access to it. It also
hosts a FUSE filesystem that allows other apps to access said storage in
a safe way. Finally, it needs to call some ioctl's to set project quota
on the lower filesystem correctly.

Test: builds, mediaprovider module gets the correct domain

/mnt/pass_through was introduced to allow the FUSE daemon unrestricted
access to the lower filesystem (or sdcardfs).
At zygote fork time, the FUSE daemon will have /mnt/pass_through/0
bind mounted to /storage instead of /mnt/user/0. To keep /sdcard
(symlink to /storage/self/primary) paths working, we create a
'self' directory with an additional 'primary' symlink to
/mnt/pass_through/0/emulated/0 which is a FUSE mount point.
The following components need varying sepolicy privileges:
Vold: Creates the self/primary symlink and mounts the lower filesystem
on /mnt/pass_through/0/emulated. So needs create_dir and mount access
+ create_file access for the symlink
zygote: In case zygote starts an app before vold sets up the paths.
This is unlikely but can happen if the FUSE daemon (a zygote forked app)
is started before system_server completes vold mounts.
Same sepolicy requirements as vold
installd: Needs to clear/destroy app data using lower filesystem
mounted on /mnt/pass_through so needs read_dir access to walk
/mnt/pass_through
priv_app (FUSE daemon): Needs to server content from the lower
filesystem mounted on /mnt/pass_through so needs read_dir access to
walk /mnt/pass_through
Bug: 135341433
Test: adb shell ls /mnt/pass_through/0/self/primary
