The netutils_wrapper is a process used by vendor code to update the
iptable rules on devices. When it update the rules for a specific chain.
The iptable module will reload the whole chain with the new rule. So
even the netutils_wrapper do not need to add any rules related to xt_bpf
module, it will still reloading the existing iptables rules about xt_bpf
module and need pass through the selinux check again when the rules are
reloading. So we have to grant it the permission to reuse the pinned
program in fs_bpf when it modifies the corresponding iptables chain so
the vendor module will not crash anymore.
Test: device boot and no more denials from netutils_wrapper

The kernel generates file creation audits when O_CREAT is passed even

We add neverallow rules to prevent mistakenly allowing unnecessary

This allows an optimization that consists in the "perfetto" cmdline
client passing directly the file descriptor for the output trace
to traced (as opposite to having traced streaming back the trace
data to "perfetto" and having that one doing the write() into file).
This reduces sensibly the memory traffic and CPU overhead of traces
with a minor change.

This CL adds the SELinux permissions required to execute
atrace and get userspace tracing events from system services.
This is to enable tracing of events coming from surfaceflinger,
audio HAL, etc.
atrace, when executed, sets a bunch of debug.atrace. properties
and sends an IPC via binder/hwbinder to tell the services to
reload that property.
This CL does NOT affect systrace. In that case (i.e. when
atrace is executed from adb/shell) atrace still runs in
the shell domain and none of those changes apply.

Bug: b/73340039
To better record the network traffic stats for each network interface.
We use xt_bpf netfilter module to do the iface stats accounting instead
of the cgroup bpf filter we currently use for per uid stats accounting.
The xt_bpf module will take pinned eBPF program as iptables rule and run
the program when packet pass through the netfilter hook. To setup the
iptables rules. netd need to be able to access bpf filesystem and run the
bpf program at boot time. The program used will still be created and
pinned by the bpfloader process.
Test: With selinux enforced, run "iptables -L -t raw" should show the
xt_bpf related rule present in bw_raw_PREROUTING chain.

This change adds the support of odm sepolicy customization, which can
be configured through the newly added build varaible:
- BOARD_ODM_SEPOLICY_DIRS += device/${ODM_NAME}/${BOM_NAME}/sepolicy
Also moving precompiled sepolicy to /odm when BOARD_ODM_SEPOLICY_DIRS
is set. On a DUT, precompiled sepolicy on /odm will override the one in
/vendor. This is intentional because /odm is the hardware customization
for /vendor and both should be updated together if desired.

Test: boot a device with /odm partition

With the new patches backported to 4.9 kernels, the bpf file system now
take the same file open flag as bpf_obj_get. So system server now need
read permission only for both bpf map and fs_bpf since we do not need
system server to edit the map. Also, the netd will always pass stdin
stdout fd to the process forked by it and do allow it will cause the
fork and execev fail. We just allow it pass the fd to bpfloader for now
until we have a better option.
Test: bpfloader start successful on devices with 4.9 kernel.
