Subject: [PATCH BlueZ 1/2] HOGP must only accept data from bonded devices.
commit 8cdbd3b09f29da29374e2f83369df24228da0ad1
Author: Alain Michaud <alainm@chromium.org>
Date: Tue Mar 10 02:35:16 2020 +0000
HOGP must only accept data from bonded devices.
HOGP 1.0 Section 6.1 establishes that the HOGP must require bonding.

Subject: [PATCH BlueZ 2/2] HID accepts bonded device connections only.
commit 3cccdbab2324086588df4ccf5f892fb3ce1f1787
Author: Alain Michaud <alainm@chromium.org>
Date: Tue Mar 10 02:35:18 2020 +0000
HID accepts bonded device connections only.
This change adds a configuration for platforms to choose a more secure
posture for the HID profile. While some older mice are known to not
support pairing or encryption, some platform may choose a more secure
posture by requiring the device to be bonded and require the
connection to be encrypted when bonding is required.
