Subject: [PATCH] adapter: Don't refresh adv_manager for non-LE devices
btd_adv_manager_refresh is called upon MGMT_SETTING_DISCOVERABLE setting change
but as only LE adapters have an adv_manager, this leads to segmentation fault
for non-LE devices:

This commit prevents the call to btd_adv_manager_refresh for non-LE devices.

Subject: [PATCH] hostname: Fix "BlueZ 5.XX" adapter name on startup
The hostname plugin listens to property changes from systemd-hostnamed
but doesn't fetch initial values. This means that unless the
PrettyHostname or StaticHostname changes, the default adapter will be
called "BlueZ 5.XX" matching the version number.
This is the case since the hostname plugin replaced the adaptername
plugin in 2012.
Fetch the initial values for PrettyHostname, StaticHostname and
Chassis when the plugin is initiated, so as to make the values
available for adapter setup.

commit e79417ed7185b150a056d4eb3a1ab528b91d2fc0
Author: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Date: Thu Jul 15 11:01:20 2021 -0700
sdpd: Fix leaking buffers stored in cstates cache
These buffer shall only be keep in cache for as long as they are
needed so this would cleanup any client cstates in the following
conditions:
- There is no cstate on the response
- No continuation can be found for cstate
- Different request opcode
- Respond with an error
- Client disconnect

Subject: [PATCH BlueZ] shared/gatt-server: Fix not properly checking for
secure flags
commit ef7316b34cf3a568694bdb0e4e83af17804dff9e (HEAD)
Author: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
Date: Tue Mar 2 11:38:33 2021 -0800
shared/gatt-server: Fix not properly checking for secure flags
When passing the mask to check_permissions all valid permissions for
the operation must be set including BT_ATT_PERM_SECURE flags.
(cherry picked from commit 00da0fb4972cf59e1c075f313da81ea549cb8738)

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.
