This is needed to allow system apps to know whether security
logging is enabled, so that they can in this case log additional
audit events.
Test: logged a security event from locally modified KeyChain app.

Add a new set of sepolicy for the process that only netd use to load
and run ebpf programs. It is the only process that can load eBPF
programs into the kernel and is only used to do that. Add some
neverallow rules regarding which processes have access to bpf objects.

boot. No selinux violation for bpfloader

If a UID is in an idle state we don't allow recording to protect
user's privacy. If the UID is in an idle state we allow recording
but report empty data (all zeros in the byte array) and once
the process goes in an active state we report the real mic data.
This avoids the race between the app being notified aboout its
lifecycle and the audio system being notified about the state
of a UID.

There is a race condition between when /data is mounted
and when processes attempt to access it. Attempting to access
/data before it's mounted causes an selinux denial. Attribute
these denials to a bug.

The NeuralNetworks runtime is a library that communicates with
NeuralNetworks HIDL services and is linked by applications. To enable
the NN runtime to use these services, applications must have explicit
sepolicy permissions to find the NN services and communicate across
binder.
This CL relaxes neverallow rules for hal_neuralnetworks_*.
Because it is affecting pre-existing neverallow rules, this CL requires
a CTS rebuild.

This gives the privilege to system apps, platform apps,
ephemeral apps, and privileged apps to receive a
UDP socket from the system server. This is being added
for supporting UDP Encapsulation sockets for IPsec, which
must be provided by the system.
This is an analogous change to a previous change that
permitted these sockets for untrusted_apps:

/proc/net/xt_qtaguid is used by apps to track their network data
use. Limit access to just zygote spawned processes - apps and
system_server, omitting access to isolated_app which is not allowed
to create network sockets.
As Android moves to eBPF for app's network data stats, access to
/proc/net/xt_qtaguid will be removed entirely. Segmenting access off
is the first step.
Bug: 68774956
This change also helps further segment and whitelist access to
files in /proc/net and is a step in the lockdown of /proc/net.

This CL lists all the exported platform properties in
private/exported_property_contexts.
Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.
Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.

Perfetto is a performance instrumentation and logging framework,
living in AOSP's /external/pefetto.
Perfetto introduces in the system one binary and two daemons
(the binary can specialize in either depending on the cmdline).
1) traced: unprivileged daemon. This is architecturally similar to logd.
It exposes two UNIX sockets:
- /dev/socket/traced_producer : world-accessible, allows to stream
tracing data. A tmpfs file descriptor is sent via SCM_RIGHTS
from traced to each client process, which needs to be able to
mmap it R/W (but not X)
- /dev/socket/traced_consumer : privilege-accessible (only from:
shell, statsd). It allows to configure tracing and read the trace
buffer.
2) traced_probes: privileged daemon. This needs to:
- access tracingfs (/d/tracing) to turn tracing on and off.
- exec atrace
- connect to traced_producer to stream data to traced.
