Functions ¶

func NewNamedPortMultiMap ¶

func NewNamedPortMultiMap() *namedPortMultiMap

func ValidatePortName ¶

func ValidatePortName(name string) (string, error)

ValidatePortName checks that the port name conforms to the IANA Service Names spec and converts the port name to lower case for case-insensitive comparisons.

Types ¶

type IPv4 ¶

type IPv4 [4]byte

IPv4 is the binary representation for encoding in binary structs.

func (IPv4) Addr ¶

func (v4 IPv4) Addr() netip.Addr

func (*IPv4) DeepCopyInto ¶

func (v4 *IPv4) DeepCopyInto(out *IPv4)

DeepCopyInto is a deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*IPv4) FromAddr ¶ added in v1.15.0

func (v4 *IPv4) FromAddr(addr netip.Addr)

FromAddr will populate the receiver with the specified address if and only if the provided address is a valid IPv4 address. Any other address, including the "invalid ip" value netip.Addr{} will zero the receiver.

func (IPv4) IsZero ¶

func (v4 IPv4) IsZero() bool

func (IPv4) String ¶

func (v4 IPv4) String() string

type IPv6 ¶

type IPv6 [16]byte

IPv6 is the binary representation for encoding in binary structs.

func (IPv6) Addr ¶

func (v6 IPv6) Addr() netip.Addr

func (*IPv6) DeepCopyInto ¶

func (v6 *IPv6) DeepCopyInto(out *IPv6)

DeepCopyInto is a deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (*IPv6) FromAddr ¶ added in v1.15.0

func (v6 *IPv6) FromAddr(addr netip.Addr)

FromAddr will populate the receiver with the specified address if and only if the provided address is a valid IPv6 address. Any other address, including the "invalid ip" value netip.Addr{} will zero the receiver.

func (IPv6) IsZero ¶ added in v1.18.0

func (v6 IPv6) IsZero() bool

func (IPv6) String ¶

func (v6 IPv6) String() string

type MACAddr ¶

type MACAddr [6]byte

MACAddr is the binary representation for encoding in binary structs.

func (*MACAddr) DeepCopyInto ¶

func (addr *MACAddr) DeepCopyInto(out *MACAddr)

DeepCopyInto is a deepcopy function, copying the receiver, writing into out. in must be non-nil.

func (MACAddr) String ¶

func (addr MACAddr) String() string

type NamedPortMap ¶

type NamedPortMap map[string]PortProto

NamedPortMap maps port names to port numbers and protocols.

func (NamedPortMap) AddPort ¶

func (npm NamedPortMap) AddPort(name string, port int, protocol string) error

AddPort adds a new PortProto to the NamedPortMap

func (NamedPortMap) GetNamedPort ¶

func (npm NamedPortMap) GetNamedPort(name string, proto u8proto.U8proto) (uint16, error)

GetNamedPort returns the port number for the named port, if any.

type NamedPortMultiMap ¶

type NamedPortMultiMap interface {
	// GetNamedPort returns the port number for the named port, if any.
	GetNamedPort(name string, proto u8proto.U8proto, epIDs iter.Seq[identity.NumericIdentity]) (uint16, error)

	// Len returns the number of Name->PortProtoSet mappings known.
	Len() int
}

NamedPortMultiMap may have multiple entries for a name if multiple PODs define the same name with different values.

type PortProto ¶

type PortProto struct {
	Proto u8proto.U8proto // 0 for any
	Port  uint16          // non-0
}

PortProto is a pair of port number and protocol and is used as the value type in named port maps.

type PortProtoSet ¶

type PortProtoSet map[PortProto]map[identity.NumericIdentity]int

PortProtoSet maps PortProto to a map of endpoint IDs to their reference counts.

func (PortProtoSet) Add ¶

func (pps PortProtoSet) Add(pp PortProto, epID identity.NumericIdentity) bool

Add increments the reference count for the epID associated with the PortProto. Returns true if the epID was not previously in the map (count was 0).

func (PortProtoSet) Delete ¶

func (pps PortProtoSet) Delete(pp PortProto, epID identity.NumericIdentity) bool

Delete decrements the reference count for the epID associated with the PortProto. It returns true if the epID was deleted.

func (PortProtoSet) Equal ¶

func (pps PortProtoSet) Equal(other PortProtoSet) bool

Equal returns true if the PortProtoSets are equal.

type XfrmStateInfo ¶ added in v1.19.0

type XfrmStateInfo struct {
	Encrypt  bool   `json:"encrypt"`
	Src      string `json:"src"`
	Dst      string `json:"dst"`
	SPI      uint32 `json:"spi"`
	ReqID    uint32 `json:"reqid"`
	AuthAlg  string `json:"auth_alg,omitempty"`
	AuthKey  string `json:"auth_key,omitempty"`
	CryptAlg string `json:"crypt_alg,omitempty"`
	CryptKey string `json:"crypt_key,omitempty"`
	AeadAlg  string `json:"aead_alg,omitempty"`
	AeadKey  string `json:"aead_key,omitempty"`
}

XfrmStateInfo represents the key information from an XFRM state This struct is used for JSON serialization of XFRM state information and is shared between cilium-dbg and cilium-cli for consistency
