Query constraint rules, (mls)constrain/(mls)validatetrans.
Parameter:
policy The policy to query.
Keyword Parameters/Class attributes:
ruletype The list of rule type(s) to match.
tclass The object class(es) to match.
tclass_regex If true, use a regular expression for
matching the rule's object class.
perms The permission(s) to match.
perms_equal If true, the permission set of the rule
must exactly match the permissions
criteria. If false, any set intersection
will match.
perms_regex If true, regular expression matching will be used
on the permission names instead of set logic.
role The name of the role to match in the
constraint expression.
role_indirect If true, members of an attribute will be
matched rather than the attribute itself.
role_regex If true, regular expression matching will
be used on the role.
type_ The name of the type/attribute to match in the
constraint expression.
type_indirect If true, members of an attribute will be
matched rather than the attribute itself.
type_regex If true, regular expression matching will
be used on the type/attribute.
user The name of the user to match in the
constraint expression.
user_regex If true, regular expression matching will
be used on the user.

Match roles/types/users in a constraint expression,
optionally by expanding the contents of attributes.
Parameters:
expr The expression to match.
criteria The criteria to match.
indirect If attributes in the expression should be expanded.
regex If regular expression matching should be used.
