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.
