    Replace "neverallow domain" by "neverallow *" · 35a14514
    Nick Kralevich authored
    Modify many "neverallow domain" rules to be "neverallow *" rules
    instead. This will catch more SELinux policy bugs where a label
    is assigned an irrelevant rule, as well as catch situations where
    a domain attribute is not assigned to a process.
