Any idea what you were doing when this happened? The reason i ask is because this is not even allowed in latest fedora as far as i can see. It is no big deal to allow updpwd_t to get attributes of the fs_t filesystem but it is certainly not common for updpwd_t to want this access i believe. If it was we probably would have gotten may more reports much earlier. > Thanks, > > > Tony > > -- > selinux mailing list > selinux@xxxxxxxxxxxxxxxxxxxxxxx > https://admin.fedoraproject.org/mailman/listinfo/selinux
