Types

type AnyValidator added in v0.21.1

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

AnyValidator returns true if any of the given validators returns true

func (AnyValidator) Validate added in v0.21.1

type AuthorizedSenderValidator added in v0.27.3

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

AuthorizedSenderValidator performs message authorization validation.

func NewAuthorizedSenderValidator added in v0.28.0

func NewAuthorizedSenderValidator(log zerolog.Logger, slashingViolationsConsumer slashing.ViolationsConsumer, getIdentity GetIdentityFunc) *AuthorizedSenderValidator

NewAuthorizedSenderValidator returns a new AuthorizedSenderValidator

func (*AuthorizedSenderValidator) PubSubMessageValidator added in v0.28.0

func (av *AuthorizedSenderValidator) PubSubMessageValidator(channel channels.Channel) PubSubMessageValidator

PubSubMessageValidator wraps Validate and returns PubSubMessageValidator callback that returns pubsub.ValidationReject if validation fails and pubsub.ValidationAccept if validation passes.

func (*AuthorizedSenderValidator) Validate added in v0.28.0

func (av *AuthorizedSenderValidator) Validate(from peer.ID, payload []byte, channel channels.Channel, protocol message.ProtocolType) (string, error)

Validate will check if the sender of a message is authorized to send the message. Using the getIdentity to get the flow identity for the sender, asserting that the sender is a staked node and not ejected. Otherwise, the message is rejected. The message is also authorized by checking that the sender is allowed to send the message on the channel. If validation fails the message is rejected, and if the validation error is an expected error, slashing data is also collected. Authorization config is defined in message.MsgAuthConfig.

type GetIdentityFunc added in v0.27.3

type GetIdentityFunc func(peer.ID) (*flow.Identity, bool)

type NotValidator added in v0.21.0
