Functions ¶

func EmptyNidPortSeq ¶

func EmptyNidPortSeq(func(identity.NumericIdentity, uint16) bool)

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) 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) 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) 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. proto must be a concrete protocol; u8proto.ANY does not match named ports.

type NamedPortMultiMap ¶

type NamedPortMultiMap interface {
	// GetNamedPort returns the port number for the named port, if any. proto
	// must be a concrete protocol; u8proto.ANY does not match named ports.
	GetNamedPort(name string, proto u8proto.U8proto, nids iter.Seq[identity.NumericIdentity]) (uint16, error)

	// GetNamedPorts returns the port numbers for the named port, if any, by
	// numeric identity. proto must be a concrete protocol; u8proto.ANY does
	// not match named ports.
	GetNamedPorts(name string, proto u8proto.U8proto, nids iter.Seq[identity.NumericIdentity]) NidPortSeq

	// Len returns the number of named port/protocol mappings known.
	Len() int
}

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

type NidPortSeq ¶

type NidPortSeq iter.Seq2[identity.NumericIdentity, uint16]

func (NidPortSeq) Ports ¶

func (s NidPortSeq) Ports() []uint16

type PortProto ¶

type PortProto struct {
	Proto u8proto.U8proto // concrete protocol; u8proto.ANY is invalid
	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 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
