Documentation

Overview

Package signalmap represents the perf event map used to signal potential congestion to Cilium agent. It is primarily managed from the datapath; Cilium side is used to create the map only. +groupName=maps

Functions

func InitMap

func InitMap(maxEntries int) error

InitMap creates the signal map in the kernel.

Types

type Key

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

Key is the index into the prog array map. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapKey

func (*Key) DeepCopy

func (in *Key) DeepCopy() *Key

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Key.

func (*Key) DeepCopyInto

func (in *Key) DeepCopyInto(out *Key)

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

func (*Key) DeepCopyMapKey

func (in *Key) DeepCopyMapKey() bpf.MapKey

DeepCopyMapKey is an autogenerated deepcopy function, copying the receiver, creating a new bpf.MapKey.

func (*Key) GetKeyPtr

func (k *Key) GetKeyPtr() unsafe.Pointer

GetKeyPtr returns the unsafe pointer to the BPF key.

func (Key) NewValue

func (k Key) NewValue() bpf.MapValue

NewValue returns a new empty instance of the structure representing the BPF map value.

func (*Key) String

func (k *Key) String() string

String converts the key into a human readable string format.

type Value

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

Value is the program ID in the prog array map. +k8s:deepcopy-gen=true +k8s:deepcopy-gen:interfaces=github.com/cilium/cilium/pkg/bpf.MapValue

func (*Value) DeepCopy

func (in *Value) DeepCopy() *Value

DeepCopy is an autogenerated deepcopy function, copying the receiver, creating a new Value.

func (*Value) DeepCopyInto

func (in *Value) DeepCopyInto(out *Value)

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

func (*Value) DeepCopyMapValue

func (in *Value) DeepCopyMapValue() bpf.MapValue

DeepCopyMapValue is an autogenerated deepcopy function, copying the receiver, creating a new bpf.MapValue.

func (*Value) GetValuePtr

func (v *Value) GetValuePtr() unsafe.Pointer

GetValuePtr returns the unsafe pointer to the BPF value.

func (*Value) String

func (v *Value) String() string

String converts the value into a human readable string format.
