-Description: sd-bus: if we receive an invalid dbus message, ignore and
- proceeed
- .
- dbus-daemon might have a slightly different idea of what a valid msg is
- than us (for example regarding valid msg and field sizes). Let's hence
- try to proceed if we can and thus drop messages rather than fail the
- connection if we fail to validate a message.
- .
- Hopefully the differences in what is considered valid are not visible
- for real-life usecases, but are specific to exploit attempts only.
