Sorry, I'm not the exploit generator guy. If I where, I would point out that the application expecting the uid to identify a person is going to behave incorrectly on the system that uses the uid to identify an application. I never said that I liked /run/user/<uid>/bus. Come to think of it, I never said I like dbus, either. > > Thanks > David > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
