Types ¶
type CtEntry ¶
type CtEntry struct {
// contains filtered or unexported fields
}
CtEntry represents an entry in the connection tracking table.
func (*CtEntry) GetValuePtr ¶ added in v0.9.0
GetValuePtr returns the unsafe.Pointer for s.
type CtEntryDump ¶
CtEntryDump represents the key and value contained in the conntrack map.
type CtKey ¶
type CtKey interface {
bpf.MapKey
// Returns human readable string representation
String() string
// ToNetwork converts fields to network byte order.
ToNetwork() CtKey
// ToHost converts fields to host byte order.
ToHost() CtKey
