The DBus specification defines DBus as an asynchronous messagepassing system, and provides no mechanism for blocking calls at the protocol level However libdbus and most DBus bindings (dbusglib, dbuspython and QtDBus) provide a "blocking" API (dbus_do_something_and_block) that implements a "pseudoblocking" behaviourIn this mode only the DBus socket is polled forDBus 1228 () == • Byteswap foreignendian messages correctly, preventing a longstanding local DoS if foreignendian messages are relayed through the dbusdaemon (CVE11, fdo #381, Debian #;Accessed using the orgfreedesktopDBusProperties interface Account — o Read only The Account on which this request was made This property cannot change UserActionTime — x (Unix_Timestamp64) Read only The time at which user action occurred, or 0 if this channel request is for some reason not involving user action

Addressing your comment on this answer about getting all properties at once, the DBus specification doesn't specify that GetAll should accept an empty string for its interface_name argument, so it's a bug if any services do accept this Instead, you must call GetAll once for each of the interfaces on the object The easiest way of doing this is to use a higherlevel DBus utility, The DBus activation system treated an exit as an activation failure, assuming that the child process which grabbed the DBus name didn't run first While we're in here, also differentiate in this code path between the servicehelperFor instance, each NetworkManager object representing a network interface implements the interface orgfreedesktopNetworkManagerDevices, which has methods like getProperties To call a method, call the method of the same name on the proxy object, passing in the interface name via the dbus_interface keyword argument

There doesn't seem to be a way to provide DBus properties on an exported object I can write methods to support the orgfreedesktopDBusProperties interface, but the DBus specification also requires that properties be listed in the object introspection data, and the Python bindings don't seem to provide a way to do thisSecurity == If you find a security vulnerability that is not known to the public, please report it privately to dbussecurity@listsfreedesktoporg or by reporting a Gitlab issue at https//gitlabfreedesktoporg/dbus/dbus/issues/new and marking it as "confidential" On Unix systems, the system bus (dbusdaemon system) is designed to be a security boundaryDbus/dbus a lightweight ipc mechanism (mirrored from https//gitlabfreedesktoporg/dbus/dbus)
