Functions ¶
func DetachXDP ¶ added in v1.15.0
DetachXDP removes an XDP program from a network interface. On kernels before 4.15, always removes the XDP program regardless of progName.
bpffsBase is typically /sys/fs/bpf/cilium, but can be overridden to a tempdir during tests.
func DeviceHasSKBProgramLoaded ¶ added in v1.16.0
DeviceHasSKBProgramLoaded returns true if the given device has a tc(x) program attached.
If checkEgress is true, returns true if there's both an ingress and egress program attached.
func NewCompilationLock ¶ added in v1.16.0
func NewCompilationLock() types.CompilationLock
Types ¶
type Params ¶ added in v1.16.0

CompilationLock datapath.CompilationLock
ConfigWriter datapath.ConfigWriter
NodeConfigNotifier *manager.NodeConfigNotifier
// Force map initialisation before loader. You should not use these otherwise.
// Some of the entries in this slice may be nil.
