This is originally allowed in healthd but the permission
was not transfered to health HAL. A typical health HAL
implementation is likely to write battery info to kernel
logs.

Test: device has battery kernel logs with health HAL
      but without healthd

Because applications should be able to set the receive
timeout on UDP encapsulation sockets, we need to allow
setsockopt(). getsockopt() is an obvious allowance as
well.

partners in some devices including some pixels.
So it should have vendor_init_settable accessibility.

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

(cherry picked from commit 886aa54b)

The kernel generates file creation audits when O_CREAT is passed even
if the file already exists - which it always does in the cgroup cases.

We add neverallow rules to prevent mistakenly allowing unnecessary
create access. We also suppress these denials, which just add noise to
the log, for the more common culprits.

In permissive mode we get more spurious denials when O_CREAT is used
with an already-existing file. They're harmless so we don't need to
audit them.

Example denials:
denied { add_name } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=dir permissive=1
denied { create } for name="trigger" scontext=u:r:init:s0 tcontext=u:object_r:sysfs_leds:s0 tclass=file permissive=1
