Functions

func ExtractChannelHeaderCertHash added in v1.2.0

func ExtractChannelHeaderCertHash(msg proto.Message) []byte

ExtractChannelHeaderCertHash extracts the TLS cert hash from a channel header.

Types

type Chain added in v1.2.0

type Chain interface {
	// Sequence returns the current config sequence number, can be used to detect config changes
	Sequence() uint64

	// PolicyManager returns the current policy manager as specified by the chain configuration
	PolicyManager() policies.Manager

	// Reader returns the chain Reader for the chain
	Reader() blockledger.Reader

	// Errored returns a channel which closes when the backing consenter has errored
	Errored() <-chan struct{}
}

Chain encapsulates chain operations and data.

type ChainManager added in v1.2.0

type ChainManager interface {
	GetChain(chainID string) Chain
}

ChainManager provides a way for the Handler to look up the Chain.

type ConfigSequencer added in v1.2.0

type ConfigSequencer interface {
	Sequence() uint64
}

ConfigSequencer provides the sequence number of the current config block.

type ExpiresAtFunc added in v1.2.0

type ExpiresAtFunc func(identityBytes []byte) time.Time

ExpiresAtFunc is used to extract the time at which an identity expires.

type Filtered added in v1.4.0

type Filtered interface {
	IsFiltered() bool
}

Filtered is a marker interface that indicates a response sender is configured to send filtered blocks

type Handler

type Handler struct {
	ExpirationCheckFunc func(identityBytes []byte) time.Time
	ChainManager        ChainManager
	TimeWindow          time.Duration
	BindingInspector    Inspector
	Metrics             *Metrics
}

Handler handles server requests.

func NewHandler added in v1.2.0

func NewHandler(cm ChainManager, timeWindow time.Duration, mutualTLS bool, metrics *Metrics, expirationCheckDisabled bool) *Handler

NewHandler creates an implementation of the Handler interface.

func (*Handler) Handle

func (h *Handler) Handle(ctx context.Context, srv *Server) error

Handle receives incoming deliver requests.

type Inspector added in v1.2.0

type Inspector interface {
	Inspect(context.Context, proto.Message) error
}

Inspector verifies an appropriate binding between the message and the context.

type InspectorFunc added in v1.2.0

type InspectorFunc func(context.Context, proto.Message) error

The InspectorFunc is an adapter that allows the use of an ordinary function as an Inspector.

func (InspectorFunc) Inspect added in v1.2.0

func (inspector InspectorFunc) Inspect(ctx context.Context, p proto.Message) error

Inspect calls inspector(ctx, p)

type Metrics added in v1.4.0

type Metrics struct {
	StreamsOpened     metrics.Counter
	StreamsClosed     metrics.Counter
	RequestsReceived  metrics.Counter
	RequestsCompleted metrics.Counter
	BlocksSent        metrics.Counter
}

func NewMetrics added in v1.4.0

func NewMetrics(p metrics.Provider) *Metrics

type PolicyChecker

type PolicyChecker interface {
	CheckPolicy(envelope *cb.Envelope, channelID string) error
}

PolicyChecker checks the envelope against the policy logic supplied by the function.

type PolicyCheckerFunc added in v1.2.0

type PolicyCheckerFunc func(envelope *cb.Envelope, channelID string) error

The PolicyCheckerFunc is an adapter that allows the use of an ordinary function as a PolicyChecker.

func (PolicyCheckerFunc) CheckPolicy added in v1.2.0

func (pcf PolicyCheckerFunc) CheckPolicy(envelope *cb.Envelope, channelID string) error

CheckPolicy calls pcf(envelope, channelID)

type Receiver added in v1.2.0

type Receiver interface {
	Recv() (*cb.Envelope, error)
}

Receiver is used to receive enveloped seek requests.

type ResponseSender added in v1.2.0

type ResponseSender interface {
	SendStatusResponse(status cb.Status) error
	SendBlockResponse(block *cb.Block) error
}

ResponseSender defines the interface a handler must implement to send responses.

type Server added in v1.2.0

type Server struct {
	Receiver
	PolicyChecker
	ResponseSender
}

Server is a polymorphic structure to support generalization of this handler to be able to deliver different type of responses.

type SessionAccessControl added in v1.2.0

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

SessionAccessControl holds access control related data for a common Envelope that is used to determine if a request is allowed for the identity associated with the request envelope.

func NewSessionAC added in v1.2.0

func NewSessionAC(chain ConfigSequencer, env *common.Envelope, policyChecker PolicyChecker, channelID string, expiresAt ExpiresAtFunc) (*SessionAccessControl, error)

NewSessionAC creates an instance of SessionAccessControl. This constructor will return an error if a signature header cannot be extracted from the envelope.

func (*SessionAccessControl) Evaluate added in v1.2.0

func (ac *SessionAccessControl) Evaluate() error

Evaluate uses the PolicyChecker to determine if a request should be allowed. The decision is cached until the identity expires or the chain configuration changes.
