Types

type Accessor

type Accessor interface {
	ContextProcessor
	RuleProcessor
}

Accessor is an interface for datapth to access contexts/rules/tokens

type ContextProcessor

type ContextProcessor interface {
	DoesContextExist(contextID string) bool
	IsContextServer(contextID string, backendip string) bool
}

ContextProcessor is an interface to provide context checks

type Datapath

type Datapath struct {

	// CacheTimeout used for Trireme auto-detecion
	ExternalIPCacheTimeout time.Duration
	// contains filtered or unexported fields
}

Datapath is the structure holding all information about a connection filter

func New

func New(
	mutualAuth bool,
	filterQueue *fqconfig.FilterQueue,
	collector collector.EventCollector,
	serverID string,
	validity time.Duration,
	service packetprocessor.PacketProcessor,
	secrets secrets.Secrets,
	mode constants.ModeType,
	procMountPoint string,
	ExternalIPCacheTimeout time.Duration,
) *Datapath

New will create a new data path structure. It instantiates the data stores needed to track sessions. The data path is started with a different call. Only required parameters must be provided. Rest a pre-populated with defaults.

func NewWithDefaults

func NewWithDefaults(
	serverID string,
	collector collector.EventCollector,
	service packetprocessor.PacketProcessor,
	secrets secrets.Secrets,
	mode constants.ModeType,
	procMountPoint string,
) *Datapath

NewWithDefaults create a new data path with most things used by default

func (*Datapath) Enforce

func (d *Datapath) Enforce(contextID string, puInfo *policy.PUInfo) error

Enforce implements the Enforce interface method and configures the data path for a new PU

func (*Datapath) GetFilterQueue

func (d *Datapath) GetFilterQueue() *fqconfig.FilterQueue

GetFilterQueue returns the filter queues used by the data path

func (*Datapath) GetPortSetInstance

func (d *Datapath) GetPortSetInstance() portset.PortSet

GetPortSetInstance returns the portset instance used by data path

func (*Datapath) Start

func (d *Datapath) Start() error

Start starts the application and network interceptors

func (*Datapath) Stop

func (d *Datapath) Stop() error

Stop stops the enforcer

func (*Datapath) Unenforce

func (d *Datapath) Unenforce(contextID string) error

Unenforce removes the configuration for the given PU

type RuleProcessor

type RuleProcessor interface {
	CheckRejectRecvRules(contextID string) (int, bool)
	CheckAcceptRecvRules(contextID string) (int, bool)
	CheckRejectTxRules(contextID string) (int, bool)
	CheckAcceptTxRules(contextID string) (int, bool)
}

RuleProcessor is an interface to access rules
