From: Florian Weimer <fweimer@redhat.com>
Date: Thu, 7 Nov 2013 09:23:35 +0100
Subject: [PATCH 1/4] build: Enable BIND_NOW
Partial RELRO means that the object is GNU_RELRO but not BIND_NOW. This
reduces the effectiveness of RELRO. bluez triggers this because it
enables PIE during the build, and rpmdiff takes this as an indicator
that the best possible hardening is desired.

From 4570164f0c90603bd07eb9e7c07e17bbafb5b5da Mon Sep 17 00:00:00 2001
From: Craig Andrews <candrews@integralblue.com>
Date: Wed, 13 Sep 2017 15:23:09 +0200
Subject: [PATCH 2/4] systemd: Add PrivateTmp and NoNewPrivileges options
PrivateTmp makes bluetoothd's /tmp and /var/tmp be inside a different
namespace. This is useful to secure access to temporary files of the
process.
NoNewPrivileges ensures that service process and all its children
can never gain new privileges through execve(), lowering the risk of
possible privilege escalations.

# and then invoke btattach with the right parameters, this is intended to be
# invoked from a hardware-activated systemd service

# For now this only suports ACPI enumerated Broadcom BT HCIs.
# This has been tested on Bay and Cherry Trail devices with both ACPI and
# PCI enumerated UARTs.
#
# Note the kernel bt developers are working on solving this entirely in the
# kernel, so it is not worth the trouble to write something better then this.
