Overview

Package enforcerproxy :: This is the implementation of the RPC client It implements the interface of Trireme Enforcer and forwards these requests to the actual remote enforcer instead of implementing locally

Types

type ProxyInfo

type ProxyInfo struct {
	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) CleanUp

func (s *ProxyInfo) CleanUp() error

CleanUp sends a cleanup command to all the remotes forcing them to exit and clean their state.

func (*ProxyInfo) EnableDatapathPacketTracing

func (s *ProxyInfo) EnableDatapathPacketTracing(ctx context.Context, contextID string, direction packettracing.TracingDirection, interval time.Duration) error

EnableDatapathPacketTracing enable nfq packet tracing in remote container

func (*ProxyInfo) EnableIPTablesPacketTracing

func (s *ProxyInfo) EnableIPTablesPacketTracing(ctx context.Context, contextID string, interval time.Duration) error

EnableIPTablesPacketTracing enable iptables tracing

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) Run

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

Run starts the the remote enforcer proxy.

func (*ProxyInfo) SetLogLevel

func (s *ProxyInfo) SetLogLevel(level constants.LogLevel) error

SetLogLevel sets log level.

func (*ProxyInfo) SetTargetNetworks

func (s *ProxyInfo) SetTargetNetworks(cfg *runtime.Configuration) 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 ProxyRPCServer

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

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

func (*ProxyRPCServer) DNSReports

func (r *ProxyRPCServer) DNSReports(req rpcwrapper.Request, resp *rpcwrapper.Response) error

DNSReports is called from the remote to post dns requests

func (*ProxyRPCServer) PostCounterEvent

func (r *ProxyRPCServer) PostCounterEvent(req rpcwrapper.Request, resp *rpcwrapper.Response) error

PostCounterEvent is called from the remote to post multiple counter records from the remoteenforcer

func (*ProxyRPCServer) PostPacketEvent

func (r *ProxyRPCServer) PostPacketEvent(req rpcwrapper.Request, resp *rpcwrapper.Response) error

PostPacketEvent is called from the remote to post multiple records from the remoteenforcer

func (*ProxyRPCServer) PostStats

func (r *ProxyRPCServer) PostStats(req rpcwrapper.Request, resp *rpcwrapper.Response) error

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