Functions

func LaunchRemoteEnforcer

func LaunchRemoteEnforcer(service packetprocessor.PacketProcessor) error

LaunchRemoteEnforcer launches a remote enforcer

Types

type RemoteEnforcer

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

RemoteEnforcer : This is the structure for maintaining state required by the remote enforcer. It is a cache of variables passed by the controller to the remote enforcer and other handles required by the remote enforcer to talk to the external processes

Why is this public when all members are private ? For golang RPC server requirements

func (*RemoteEnforcer) EnableDatapathPacketTracing

func (s *RemoteEnforcer) EnableDatapathPacketTracing(req rpcwrapper.Request, resp *rpcwrapper.Response) error

EnableDatapathPacketTracing enable nfq datapath packet tracing

func (*RemoteEnforcer) EnableIPTablesPacketTracing

func (s *RemoteEnforcer) EnableIPTablesPacketTracing(req rpcwrapper.Request, resp *rpcwrapper.Response) error

EnableIPTablesPacketTracing enables iptables trace packet tracing

func (*RemoteEnforcer) Enforce

func (s *RemoteEnforcer) Enforce(req rpcwrapper.Request, resp *rpcwrapper.Response) error

Enforce this method calls the enforce method on the enforcer created during initenforcer

func (*RemoteEnforcer) EnforcerExit

func (s *RemoteEnforcer) EnforcerExit(req rpcwrapper.Request, resp *rpcwrapper.Response) error

EnforcerExit is processing messages from the remote that are requesting an exit. In this case we simply cancel the context.

func (*RemoteEnforcer) InitEnforcer

func (s *RemoteEnforcer) InitEnforcer(req rpcwrapper.Request, resp *rpcwrapper.Response) error

InitEnforcer is a function called from the controller using RPC. It intializes data structure required by the remote enforcer

func (*RemoteEnforcer) SetTargetNetworks

func (s *RemoteEnforcer) SetTargetNetworks(req rpcwrapper.Request, resp *rpcwrapper.Response) error

SetTargetNetworks calls the same method on the actual enforcer

func (*RemoteEnforcer) Unenforce

func (s *RemoteEnforcer) Unenforce(req rpcwrapper.Request, resp *rpcwrapper.Response) error

Unenforce this method calls the unenforce method on the enforcer created from initenforcer

func (*RemoteEnforcer) UpdateSecrets

func (s *RemoteEnforcer) UpdateSecrets(req rpcwrapper.Request, resp *rpcwrapper.Response) error

UpdateSecrets updates the secrets used by the remote enforcer

type RemoteIntf

type RemoteIntf interface {
	// InitEnforcer is a function called from the controller using RPC.
	// It intializes data structure required by the remote enforcer
	InitEnforcer(req rpcwrapper.Request, resp *rpcwrapper.Response) error

	//Unenforce this method calls the unenforce method on the enforcer created from initenforcer
	Unenforce(req rpcwrapper.Request, resp *rpcwrapper.Response) error

	//Enforce this method calls the enforce method on the enforcer created during initenforcer
	Enforce(req rpcwrapper.Request, resp *rpcwrapper.Response) error

	// EnforcerExit this method is called when  we received a killrpocess message from the controller
	// This allows a graceful exit of the enforcer
	EnforcerExit(req rpcwrapper.Request, resp *rpcwrapper.Response) error
}

RemoteIntf is the interface implemented by the remote enforcer
