Functions

func NewDefaultProxyEnforcer

func NewDefaultProxyEnforcer(serverID string,
	collector collector.EventCollector,
	secrets secrets.Secrets,
	rpchdl rpcwrapper.RPCClient,
	procMountPoint string,
	targetNetworks []string,
	runtimeError chan *policy.RuntimeError,
) enforcer.Enforcer

NewDefaultProxyEnforcer This is the default datapth method. THis is implemented to keep the interface consistent whether we are local or remote enforcer.

func NewProxyEnforcer

func NewProxyEnforcer(mutualAuth bool,
	filterQueue *fqconfig.FilterQueue,
	collector collector.EventCollector,
	service packetprocessor.PacketProcessor,
	secrets secrets.Secrets,
	serverID string,
	validity time.Duration,
	rpchdl rpcwrapper.RPCClient,
	cmdArg string,
	procMountPoint string,
	ExternalIPCacheTimeout time.Duration,
	packetLogs bool,
	targetNetworks []string,
	runtimeError chan *policy.RuntimeError,
) enforcer.Enforcer

NewProxyEnforcer creates a new proxy to remote enforcers.

Types

type ProxyInfo

type ProxyInfo struct {
	MutualAuth bool
	PacketLogs bool
	Secrets    secrets.Secrets

	ExternalIPCacheTimeout time.Duration

	sync.RWMutex
	// contains filtered or unexported fields
}

ProxyInfo is the struct used to hold state about active enforcers in the system

func (*ProxyInfo) Enforce

func (s *ProxyInfo) Enforce(contextID string, puInfo *policy.PUInfo) error

Enforce method makes a RPC call for the remote enforcer enforce method

func (*ProxyInfo) GetFilterQueue

func (s *ProxyInfo) GetFilterQueue() *fqconfig.FilterQueue

GetFilterQueue returns the current FilterQueueConfig.

func (*ProxyInfo) GetPortSetInstance

func (s *ProxyInfo) GetPortSetInstance() portset.PortSet

GetPortSetInstance returns nil for the proxy

func (*ProxyInfo) InitRemoteEnforcer

func (s *ProxyInfo) InitRemoteEnforcer(contextID string) error

InitRemoteEnforcer method makes a RPC call to the remote enforcer

func (*ProxyInfo) Run

func (s *ProxyInfo) Run(ctx context.Context) error

Run starts the the remote enforcer proxy.

func (*ProxyInfo) SetTargetNetworks

func (s *ProxyInfo) SetTargetNetworks(networks []string) error

SetTargetNetworks does the RPC call for SetTargetNetworks to the corresponding remote enforcers

func (*ProxyInfo) Unenforce

func (s *ProxyInfo) Unenforce(contextID string) error

Unenforce stops enforcing policy for the given contextID.

func (*ProxyInfo) UpdateSecrets

func (s *ProxyInfo) UpdateSecrets(token secrets.Secrets) error

UpdateSecrets updates the secrets used for signing communication between trireme instances

type StatsServer

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

StatsServer This struct is a receiver for Statsserver and maintains a handle to the RPC StatsServer.

func (*StatsServer) GetStats

func (r *StatsServer) GetStats(req rpcwrapper.Request, resp *rpcwrapper.Response) error

GetStats is the function called from the remoteenforcer when it has new flow events to publish.
