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 FilterSetter ¶ added in v1.19.0
func LoadSockTerm ¶ added in v1.19.0
func LoadSockTerm(l *slog.Logger, sockRevNat4, sockRevNat6 *bpf.Map) (*bpfgen.SockTermPrograms, FilterSetter, error)
LoadSockTerm loads the cil_sock_udp_destroy_v4, cil_sock_tcp_destroy_v4, cil_sock_tcp_destroy_v6, and cil_sock_udp_destroy_v6 programs. It returns a handle to the programs and a function that sets the socket filter.
type Params ¶ added in v1.16.0
type Params struct {
cell.In
JobGroup job.Group
Logger *slog.Logger
Sysctl sysctl.Sysctl
