Found when making the tests for permissive MTE, which are part of the
CTS test suite because I really, really don't want to fork hundreds of
lines of Java glue. But, CTS tests aren't supposed to only run on rooted
devices (even though there's examples of this in the tree already).
I think either way, ideologically, we should allow non-root users to
enable permissive MTE. This would be useful for a person who wants to
dogfood MTE with all apps on, but use a retail build. I can think of at
least a few researchers that would probably find this useful.

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.

That's clearly desirable for example for vendor use of xt_bpf programs.
I believe that also holds true for prog_load which is checked

like vendor tracepoint attachment.

This change adds rules for system properties "sys.snapshotctl.map" and
"sys.snapshotctl.unmap", for controlling snapshotctl.
This change also adds the missing rules for snapshotctl to perform its
job. Initially, the rules for snapshotctl were added by
http://r.android.com/1126904, for running snapshotctl through init
(http://r.android.com/1123645). However, the trigger was then removed by
http://r.android.com/1239286. Since then, snapshotctl can be only run by
the root shell, in which case it is run in the "su" domain, so the rules
are not tested and therefore get stale over time. To make snapshotctl
function properly when run by init, we need to add the missing rules.

The tracing filesystem used to be mounted on /sys/kernel/debug/tracing,
but is nowaways available at /sys/kernel/tracing.
Since debugfs itself is no longer mounted on release devices, there is
no need for rules that relax specific .../debug/tracing/... files to be
available on release devices. Leave them as debugfs_tracing_debug.
Not touching other labels such as debugfs_tracing_printk_formats in case
there are debug-only tools that grant themselves access to just that
label. Might revisit those in a different patch.

This is a tracing control file that userspace can read/write an ascii
number (e.g. "50"). In turn, it controls the behaviour of blocking
read(), splice(), and poll() on the tracing kernel ring buffer fds.
A blocked syscall will only be woken up once the kernel fills the buffer
past the "buffer_percent" watermark (so 50% -> half-full).
We'll be using this file in perfetto's traced_probes, but it should also
be safe to expose to other users of the tracing file system (aka
debugfs_tracing in sepolicy) on release builds.

The default policy for the "lockdown" access vector on Android was
introduced in commit bcfca1a6. While the "confidentiality" permission
was granted to all processes, the "integrity" was marked as
neverallowed.
Upstream, the support for that access vector was removed from kernel
5.16 onwards.
It was found that the "integrity" permission either does not apply to
Android or duplicates other access control (e.g., capabilities
sys_admin).
Instead of simply removing the neverallow rule, the access is granted to
all processes. This will prevent the proliferation of references to this
access vector in vendors' policies and ultimately facilitate its
removal.

1, /metadata/aconfig is the directory that stores aconfig storage
related protobuf files and flag value files boot copy. Grant read
access to everybody. But limit the write access only to init and
aconfig storage service process (to be created later)
2, /metadata/aconfig/flags is the sub directory that stores persistent
aconfig value files.Initially set it up to be accessible by
system_server process only . When aconfig storage service process is
created, will add another permission to storage service process.
Context to why we are hosting flag data on /metadata partition:
Android is adopting trunk stable workflow, flagging and A/B testing is
essential to every platform component. We need some place to host the
flag that are accessible to system processes that starts before /data
partition becomes available.
In addition, there has been a long discussion regarding utilizing
/metadata partition for some process data, another example is mainline
modules, we are trying to make them to be able to be mounted earlier,
but cannot due to /data availability.
