ImportSessionRules imports a list of session rules into a newly created list of ContivRule tables, suitable for Resync with the cache.

Types

type SessionRule

type SessionRule struct {
	TransportProto uint8
	IsIP4          uint8
	LclIP          [16]byte
	LclPlen        uint8
	RmtIP          [16]byte
	RmtPlen        uint8
	LclPort        uint16
	RmtPort        uint16
	ActionIndex    uint32
	AppnsIndex     uint32
	Scope          uint8
	Tag            [64]byte
}

SessionRule defines and groups the fields of a VPP session rule.

func ExportSessionRules

func ExportSessionRules(rules []*renderer.ContivRule, podID *podmodel.ID, podIP net.IP, contiv contiv.API, log logging.Logger) []*SessionRule

ExportSessionRules converts Contiv rules into the corresponding set of session rules. Set *podID* to nil if the rules are from the global table.

func (*SessionRule) Compare

func (sr *SessionRule) Compare(sr2 *SessionRule, compareTag bool) int

Compare returns -1, 0, 1 if this<sr2 or this==sr2 or this>sr2, respectively. Session rules have a total order defined on them.

func (*SessionRule) Copy

func (sr *SessionRule) Copy() *SessionRule

Copy creates a deep copy of the Session rule.

func (*SessionRule) String

func (sr *SessionRule) String() string
