Functions

func BreakdownRule

func BreakdownRule(rule authorizationapi.PolicyRule) []authorizationapi.PolicyRule

BreakdownRule takes a rule and builds an equivalent list of rules that each have at most one verb, one resource, and one resource name

func CompactRules

func CompactRules(rules []authorizationapi.PolicyRule) ([]authorizationapi.PolicyRule, error)

CompactRules combines rules that contain a single APIGroup/Resource, differ only by verb, and contain no other attributes. this is a fast check, and works well with the decomposed "missing rules" list from a Covers check.

func ConfirmNoEscalation

func ConfirmNoEscalation(ctx apirequest.Context, resource schema.GroupResource, name string, ruleResolver, cachedRuleResolver AuthorizationRuleResolver, role authorizationinterfaces.Role) error

func Covers

func Covers(ownerRules, servantRules []authorizationapi.PolicyRule) (bool, []authorizationapi.PolicyRule)

Covers determines whether or not the ownerRules cover the servantRules in terms of allowed actions. It returns whether or not the ownerRules cover and a list of the rules that the ownerRules do not cover.

func EscalationAllowed

func EscalationAllowed(ctx apirequest.Context) bool

EscalationAllowed returns true if a particular user is allowed to escalate his powers

Types

type AuthorizationRuleResolver

type AuthorizationRuleResolver interface {
	GetRoleBindings(namespace string) ([]authorizationinterfaces.RoleBinding, error)
	GetRole(roleBinding authorizationinterfaces.RoleBinding) (authorizationinterfaces.Role, error)
	// RulesFor returns the list of rules that apply to a given user in a given namespace and error.  If an error is returned, the slice of
	// PolicyRules may not be complete, but it contains all retrievable rules.  This is done because policy rules are purely additive and policy determinations
	// can be made on the basis of those rules that are found.
	RulesFor(info user.Info, namespace string) ([]authorizationapi.PolicyRule, error)
}

type DefaultRuleResolver

type DefaultRuleResolver struct {
	// contains filtered or unexported fields
}

func NewDefaultRuleResolver

func NewDefaultRuleResolver(policyGetter authorizationlister.PolicyLister, bindingLister authorizationlister.PolicyBindingLister, clusterPolicyGetter authorizationlister.ClusterPolicyLister, clusterBindingLister authorizationlister.ClusterPolicyBindingLister) *DefaultRuleResolver

func (*DefaultRuleResolver) GetRole

func (a *DefaultRuleResolver) GetRole(roleBinding authorizationinterfaces.RoleBinding) (authorizationinterfaces.Role, error)

func (*DefaultRuleResolver) GetRoleBindings

func (a *DefaultRuleResolver) GetRoleBindings(namespace string) ([]authorizationinterfaces.RoleBinding, error)

func (*DefaultRuleResolver) RulesFor

func (a *DefaultRuleResolver) RulesFor(user user.Info, namespace string) ([]authorizationapi.PolicyRule, error)

RulesFor returns the list of rules that apply to a given user in a given namespace and error. If an error is returned, the slice of PolicyRules may not be complete, but it contains all retrievable rules. This is done because policy rules are purely additive and policy determinations can be made on the basis of those rules that are found.
