Types

type ExtraValue added in v1.4.0 

type ExtraValue []string

ExtraValue masks the value so protobuf can generate +protobuf.nullable=true

func (ExtraValue) DeepCopy added in v1.10.0 

func (in ExtraValue) DeepCopy() ExtraValue

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new ExtraValue.

func (ExtraValue) DeepCopyInto added in v1.10.0 

func (in ExtraValue) DeepCopyInto(out *ExtraValue)

DeepCopyInto is an autogenerated deepcopy function, copying the receiver, writing into out. in must be non-nil.

type FieldSelectorAttributes added in v1.31.0 

type FieldSelectorAttributes struct {
	// rawSelector is the serialization of a field selector that would be included in a query parameter.
	// Webhook implementations are encouraged to ignore rawSelector.
	// The kube-apiserver's *SubjectAccessReview will parse the rawSelector as long as the requirements are not present.
	// +optional
	RawSelector string

	// requirements is the parsed interpretation of a field selector.
	// All requirements must be met for a resource instance to match the selector.
	// Webhook implementations should handle requirements, but how to handle them is up to the webhook.
	// Since requirements can only limit the request, it is safe to authorize as unlimited request if the requirements
	// are not understood.
	// +optional
	// +listType=atomic
	Requirements []metav1.FieldSelectorRequirement
}

FieldSelectorAttributes indicates a field limited access. Webhook authors are encouraged to * ensure rawSelector and requirements are not both set * consider the requirements field if set * not try to parse or consider the rawSelector field if set. This is to avoid another CVE-2022-2880 (i.e. getting different systems to agree on how exactly to parse a query is not something we want), see https://www.oxeye.io/resources/golang-parameter-smuggling-attack for more details. For the *SubjectAccessReview endpoints of the kube-apiserver: * If rawSelector is empty and requirements are empty, the request is not limited. * If rawSelector is present and requirements are empty, the rawSelector will be parsed and limited if the parsing succeeds. * If rawSelector is empty and requirements are present, the requirements should be honored * If rawSelector is present and requirements are present, the request is invalid.

	Requirements []metav1.LabelSelectorRequirement
}

	// Status is filled in by the server and indicates whether the request is allowed or not
	Status SubjectAccessReviewStatus

type SelfSubjectAccessReviewSpec struct {
	// ResourceAttributes describes information for a resource access request
	ResourceAttributes *ResourceAttributes
	// NonResourceAttributes describes information for a non-resource access request
	NonResourceAttributes *NonResourceAttributes
}

SelfSubjectAccessReviewSpec is a description of the access request. Exactly one of ResourceAttributes and NonResourceAttributes must be set

func (*SelfSubjectAccessReviewSpec) DeepCopy added in v1.8.0

	// Spec holds information about the request being evaluated.
	Spec SelfSubjectRulesReviewSpec

	// Status is filled in by the server and indicates the set of actions a user can perform.
	Status SubjectRulesReviewStatus
}

SelfSubjectRulesReview enumerates the set of actions the current user can perform within a namespace. The returned list of actions may be incomplete depending on the server's authorization mode, and any errors experienced during the evaluation. SelfSubjectRulesReview should be used by UIs to show/hide actions, or to quickly let an end user reason about their permissions. It should NOT Be used by external systems to drive authorization decisions as this raises confused deputy, cache lifetime/revocation, and correctness concerns. SubjectAccessReview, and LocalAccessReview are the correct way to defer authorization decisions to the API server.

type SubjectAccessReviewStatus 

type SubjectAccessReviewStatus struct {
	// Allowed is required. True if the action would be allowed, false otherwise.
	Allowed bool
	// Denied is optional. True if the action would be denied, otherwise
	// false. If both allowed is false and denied is false, then the

	Denied bool
	// Reason is optional.  It indicates why a request was allowed or denied.
	Reason string
	// EvaluationError is an indication that some error occurred during the authorization check.
	// It is entirely possible to get an error and be able to continue determine authorization status in spite of it.
	// For instance, RBAC can be missing a role, but enough roles are still present and bound to reason about the request.
	EvaluationError string
}

SubjectAccessReviewStatus represents the current state of a SubjectAccessReview.

func (*SubjectAccessReviewStatus) DeepCopy added in v1.8.0

	// The list ordering isn't significant, may contain duplicates, and possibly be incomplete.

	// encountered when an authorizer, such as an external authorizer, doesn't support rules evaluation.
	Incomplete bool
	// EvaluationError can appear in combination with Rules. It indicates an error occurred during
	// rule evaluation, such as an authorizer that doesn't support rule evaluation, and that
	// ResourceRules and/or NonResourceRules may be incomplete.
	EvaluationError string
}

SubjectRulesReviewStatus contains the result of a rules check. This check can be incomplete depending on the set of authorizers the server is configured with and any errors experienced during evaluation. Because authorization rules are additive, if a rule appears in a list it's safe to assume the subject has that permission, even if that list is incomplete.
