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.

getprop is broken out from toolbox/toybox, however its permissions
should remain the same, so label it appropriately.

This reverts commit 640e595a. The
corresponding code in libcutils was removed, so this is now unneeded.

1) fc_sort is not needed as there is no reason to sort system
   properties, so this is removed and replaced with a simply copy
2) Use the new property_info_checker instead of checkfc for
   validating property information.  This supports exact match
   properties and will be extended to verify property schemas in the
   future.

Bug: 36001741
Test: verify bullhead's property contexts correct
Test: verify faulty property contexts result in failures
Change-Id: Id9bbf401f385206e6907449a510e3111424ce59e

After offline discussions, we decided that this was the proper
exception to the neverallow rule.

Test: Built policy.

This CL creates a traceur_app domain with userdebug privileges akin to
what shell has with regards to being able to find most services on
device. Previously, traceur was running as shell which was an
unintentional abuse of selinux architecture.

Bug: 68126425
Test: Traceur functions outside of shell user privilege

For consistency with zygote, allow webview_zygote to list directories
in /system.

Test: Boot Taimen. Verify webiew_zygote denials during boot.

The system server is responsible for providing the network traffic
stats to Apps and services. Allow it to directly reading the eBPF maps
that stored these information can make the process of getting traffic
stats simplier.

Test: No selinux rule violation of system server reading netd bpf object
Bug: 30950746
Change-Id: I6d9438d1ed7c9bab45a708f5d2a85eb22f5e8170

Add the new classes for eBPF map and program to limit the access to eBPF
object. Add corresponding rules to allow netd module initialize bpf
programs and maps, use the program and read/wirte to eBPF maps.

Test: no bpf sepolicy violations when device boot
Change-Id: I63c35cd60f1972d4fb36ef2408da8d5f2246f7fd

Some necessary sepolicy rule changes for init process to create directory,
mount cgroupv2 module and mount bpf filesystem. Also allow netd to create
and pin bpf object as files and read it back from file under the
directory where bpf filesystem is mounted.

Test: bpf maps show up under /sys/fs/bpf/
