## Dbus Abstractions

Access to common dbus interface is done using the abstractions under **[`abstractions/bus/`](https://github.com/roddhjav/apparmor.d/tree/main/apparmor.d/abstractions/bus)**. They are kept minimal on purpose. The goal is not to give full talk access an interface but to provide a *read only* like view of it. For more access, use the dbus directive

Access to common dbus interface is done using the abstractions under **[`abstractions/bus/`](https://github.com/roddhjav/apparmor.d/tree/main/apparmor.d/abstractions/bus)**. They are kept minimal on purpose. The goal is not to give full talk access an interface but to provide a *read-only* like view of it. It may be required to have a look at the dbus interface documentation to check what method can be safely allowed.

|

For more access, simply use the [`dbus: talk`](#dbus-directive) directive.

The directive format is on purpose very similar to apparmor dbus rules. However, there are some restrictions:
|
||||
|
||||
- `bus` and `name` are mandatory and will break the build if ignored.
|
||||
- For the *talk* sub directive, profile name under a `label` is also mandatory
|
||||
- `interface` can optionally be given when it is different to the dbus path.
|
||||
- `path` can optionally be given when it is different to the dbus name.
|
||||
- It is still a comment: the rule must not end with a comma, multiline directive is not supported.
