Types

type GeneralManager

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

GeneralManager is used to load multiple eBPF programs with a custom check (if then) done in prog.c The manager simply adds a feature (byte) of each program to a map that is shared between the userspace and kernel. When packet arrives, the C code checks for each feature (if it is set) and executes each enabled program (e.g., dns_fwd.c and wg_proxy.c).
