It is still added in by systemd-bus-proxyd + for old dbus1 clients, and it is available if libsystemd-bus is used + against the classic dbus1 daemon. If you want to write compatible + code with libsystem-bus you need to explicitly subscribe to + NameOwnerChanged signals and just ignore NameAcquired/NameLost + +- Applications have to deal with spurious signals they didn't expect, + due to the probabilistic bloom filters. They need to handle this + anyway, given that any client can send anything to arbitrary clients + anyway, even in dbus1, so not much changes. + +- clients of the system bus when kdbus is used must roll their own + security. Only legacy dbus1 clients get the old XML policy enforced, + which is implemented by systemd-bus-proxyd. + +- Serial numbers of synthesized messages are always (uint32_t) -1. + +- The org.freedesktop.DBus "driver" service is not special on + kdbus. It is a bus activated service like any other with its own + unique name. + +- NameOwnerChanged is a synthetic message, generated locally and not + by the driver. |
