Query genfscon statements.
Parameter:
policy The policy to query.
Keyword Parameters/Class attributes:
fs The criteria to match the file system type.
fs_regex If true, regular expression matching
will be used on the file system type.
path The criteria to match the path.
path_regex If true, regular expression matching
will be used on the path.
user The criteria to match the context's user.
user_regex If true, regular expression matching
will be used on the user.
role The criteria to match the context's role.
role_regex If true, regular expression matching
will be used on the role.
type_ The criteria to match the context's type.
type_regex If true, regular expression matching
will be used on the type.
range_ The criteria to match the context's range.
range_subset If true, the criteria will match if it is a subset
of the context's range.
range_overlap If true, the criteria will match if it overlaps
any of the context's range.
range_superset If true, the criteria will match if it is a superset
of the context's range.
range_proper If true, use proper superset/subset operations.
No effect if not using set operations.
