Functions

func RequireCapabilities

func RequireCapabilities() error

RequireCapabilities checks for eBPF support and returns an error if not available. This is intended to be called at startup to provide a clear error message.

Types

type Capabilities

type Capabilities struct {
	// KernelVersion is the running kernel version string
	KernelVersion string
	// KernelSupported indicates if the kernel version supports eBPF TC programs
	KernelSupported bool
	// BPFSyscall indicates if the BPF syscall is available
	BPFSyscall bool
	// CanCreatePrograms indicates if we can create eBPF programs
	CanCreatePrograms bool
	// HasCAP_BPF indicates if CAP_BPF capability is available
	HasCAP_BPF bool
	// HasCAP_NET_ADMIN indicates if CAP_NET_ADMIN capability is available
	HasCAP_NET_ADMIN bool
	// Error contains any error encountered during detection
	Error error
}

Capabilities represents the eBPF capabilities of the current environment

func Detect

func Detect() *Capabilities

Detect probes the current environment for eBPF capabilities

func (*Capabilities) IsSupported

func (c *Capabilities) IsSupported() bool

IsSupported returns true if all required eBPF capabilities are available

func (*Capabilities) Summary

func (c *Capabilities) Summary() string

Summary provides a human-readable summary of capabilities
