	IPsetPrefix

	Reset()
}

IPSetManager interface is used by supervisor. This interface provides the supervisor to create ipsets corresponding to service ID.

func V4() IPSetManager

V4 returns the ipv4 instance of ipsetmanager

func V4test

func V4test() IPSetManager

V4test returns the test handler for ipv4

func V6

func V6() IPSetManager

V6 returns the ipv6 instance of ipsetmanager

func V6test

func V6test() IPSetManager

V6test returns the test handler for ipv6

type IPsetPrefix

type IPsetPrefix interface {
	//GetIPsetPrefix returns the prefix.
	GetIPsetPrefix() string
}

IPsetPrefix returns the prefix used to construct the ipset.

type Ipset

type Ipset interface {
	Add(entry string, timeout int) error
	AddOption(entry string, option string, timeout int) error
	Del(entry string) error
	Destroy() error
	Flush() error
	Test(entry string) (bool, error)
}

Ipset is an abstraction of all the methods an implementation of userspace ipsets need to provide.

type IpsetProvider

type IpsetProvider interface {
	NewIpset(name string, ipsetType string, p *ipset.Params) (Ipset, error)
	GetIpset(name string) Ipset
	DestroyAll(prefix string) error
	ListIPSets() ([]string, error)
}

IpsetProvider returns a fabric for Ipset.

type ProxyL4

type ProxyL4 interface {
	//CreateProxySets creates the ipsets to implement L4/L7 services
	CreateProxySets(contextID string) error
	//GetProxyIPsetNames returns the ipset strings that correspond to the pu
	GetProxySetNames(contextID string) (string, string)
	//DestroyProxySet destroys the ipsets being used for L4/L7 services
	DestroyProxySets(contextID string)
	//FlushProxySets flushes the proxy IPsets
	FlushProxySets(contextID string)
	//AddIPPortToDependentService adds ip port to the dependent service
	AddIPPortToDependentService(contextID string, ip *net.IPNet, port string) error
	//AddPortToExposedService adds the port that this service is exposing
	AddPortToExposedService(contextID string, port string) error
}

ProxyL4 interface is used to interact with the ipsets required for L4/L7 Services. These include dependent services and exposed Services

type ServerL3

type ServerL3 interface {
	//CreateServerPortSet creates the ipset.
	CreateServerPortSet(contextID string) error
	//GetServerPortSetName returns the name of the portset created
	GetServerPortSetName(contextID string) string
	//DestroyServerPortSet destroys the server port set.
	DestroyServerPortSet(contextID string) error
	//AddPortToServerPortSet adds port to the portset.
	AddPortToServerPortSet(contextID string, port string) error
	//DeletePortFromServerPortSet deletes the port from port set.
	DeletePortFromServerPortSet(contextID string, port string) error
}

ServerL3 interface is used to interact with the ipsets required to program ports that the server(PU) listens on in L3 datapath.
