Constants

const (
	// HostLocalSourceBit is the bit of the iptables fwmark space to mark locally generated packets.
	// Value must be within the range [0, 31].
	HostLocalSourceBit = 0
)

const (
	// NodeMACAddressAnnotationKey represents the key of the Node's MAC address in the Annotations of the Node.
	NodeMACAddressAnnotationKey string = "node.antrea.io/mac-address"
)

Variables

var (
	// HostLocalSourceMark is the mark generated from HostLocalSourceBit.
	HostLocalSourceMark = uint32(1 << HostLocalSourceBit)

	// SNATIPMarkMask is the bits of packet mark that stores the ID of the
	// SNAT IP for a "Pod -> external" egress packet, that is to be SNAT'd.
	SNATIPMarkMask = uint32(0xFF)
)

Types

type Address

type Address interface {
	GetMatchValue() string
	GetMatchKey(addrType AddressType) *MatchKey
	GetValue() interface{}
}

type AddressCategory

type AddressCategory uint8

const (
	IPAddr AddressCategory = iota
	IPNetAddr
	OFPortAddr
	L4PortAddr
	UnSupported
)

type AddressType

type AddressType int

const (
	SrcAddress AddressType = iota
	DstAddress
)

type BitRange

type BitRange struct {
	Value uint16
	Mask  *uint16
}

A BitRange is a representation of a range of values from base value with a bitmask applied.

type ByPriority

type ByPriority []Priority

ByPriority sorts a list of Priority by their relative TierPriority, PolicyPriority and RulePriority, in that order. It implements sort.Interface.

func (ByPriority) Len

func (bp ByPriority) Len() int

func (ByPriority) Less

func (bp ByPriority) Less(i, j int) bool

func (ByPriority) Swap

func (bp ByPriority) Swap(i, j int)

type EntityReference

type EntityReference struct {
	// Pod maintains the reference to the Pod.
	Pod *v1beta2.PodReference
	// ExternalEntity maintains the reference to the ExternalEntity.
	ExternalEntity *v1beta2.ExternalEntityReference
}

EntityReference represents a reference to either a Pod or an ExternalEntity.

type MatchKey

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

func NewMatchKey

func NewMatchKey(proto binding.Protocol, valueCategory AddressCategory, keyString string) *MatchKey

func (*MatchKey) GetKeyString

func (m *MatchKey) GetKeyString() string

func (*MatchKey) GetOFProtocol

func (m *MatchKey) GetOFProtocol() binding.Protocol

func (*MatchKey) GetValueCategory

func (m *MatchKey) GetValueCategory() AddressCategory

type PolicyRule

type PolicyRule struct {
	Direction     v1beta2.Direction
	From          []Address
	To            []Address
	Service       []v1beta2.Service
	Action        *secv1alpha1.RuleAction
	Priority      *uint16
	Name          string
	FlowID        uint32
	TableID       binding.TableIDType
	PolicyRef     *v1beta2.NetworkPolicyReference
	EnableLogging bool
}

PolicyRule groups configurations to set up conjunctive match for egress/ingress policy rules.

func (*PolicyRule) IsAntreaNetworkPolicyRule

func (r *PolicyRule) IsAntreaNetworkPolicyRule() bool

IsAntreaNetworkPolicyRule returns if a PolicyRule is created for Antrea NetworkPolicy types.

type Priority

type Priority struct {
	TierPriority   int32
	PolicyPriority float64
	RulePriority   int32
}

Priority is a struct that is composed of Antrea NetworkPolicy priority, rule priority and Tier priority. It is used as the basic unit for priority sorting.

func (*Priority) Equals

func (p *Priority) Equals(p2 Priority) bool

func (*Priority) InSamePriorityZone

func (p *Priority) InSamePriorityZone(p2 Priority) bool

InSamePriorityZone returns true if two Priorities are of the same Tier and same priority at policy level.

func (*Priority) IsConsecutive

func (p *Priority) IsConsecutive(p2 Priority) bool

IsConsecutive returns true if two Priorties are immediately next to each other.

func (*Priority) Less

func (p *Priority) Less(p2 Priority) bool

type RoundInfo

type RoundInfo struct {
	RoundNum uint64
	// PrevRoundNum is nil if this is the first round or the previous round
	// number could not be retrieved.
	PrevRoundNum *uint64
}

RoundInfo identifies the current agent "round". Each round is indentified by a round number, which is incremented every time the agent is restarted. The round number is persisted on the Node in OVSDB.

type RuleMetric

type RuleMetric struct {
	Bytes, Packets, Sessions uint64
}

func (*RuleMetric) Merge

func (m *RuleMetric) Merge(m1 *RuleMetric)
