Subject: [PATCH 1/2] obex: Use GLib helper function to manipulate paths
Instead of trying to do it by hand. This also makes sure that
relative paths aren't used by the agent.

Subject: [PATCH BlueZ] sdpd: Fix leaking buffers stored in cstates cache
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
Fixes: https://github.com/bluez/bluez/security/advisories/GHSA-3fqg-r8j5-f5xq

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.
