	help
	  BPF programs are normally handled by a BPF interpreter. This option
	  allows the kernel to generate native code when a program is loaded
	  into the kernel. This will significantly speed-up processing of BPF
	  programs.

	  Note, an admin should enable this feature changing:
	  /proc/sys/net/core/bpf_jit_enable
	  /proc/sys/net/core/bpf_jit_harden   (optional)
	  /proc/sys/net/core/bpf_jit_kallsyms (optional)

config BPF_JIT_ALWAYS_ON
	bool "Permanently enable BPF JIT and remove BPF interpreter"
	depends on BPF_SYSCALL && HAVE_EBPF_JIT && BPF_JIT
	help
	  Enables BPF JIT and removes BPF interpreter to avoid speculative
	  execution of BPF instructions by the interpreter.

	  When CONFIG_BPF_JIT_ALWAYS_ON is enabled, /proc/sys/net/core/bpf_jit_enable
	  is permanently set to 1 and setting any other value than that will
	  return failure.

config BPF_JIT_DEFAULT_ON

	depends on HAVE_EBPF_JIT && BPF_JIT

config BPF_UNPRIV_DEFAULT_OFF
	bool "Disable unprivileged BPF by default"
	default y
	depends on BPF_SYSCALL
	help
	  Disables unprivileged BPF by default by setting the corresponding
	  /proc/sys/kernel/unprivileged_bpf_disabled knob to 2. An admin can
	  still reenable it by setting it to 0 later on, or permanently
	  disable it by setting it to 1 (from which no other transition to
	  0 is possible anymore).

	  Unprivileged BPF could be used to exploit certain potential
	  speculative execution side-channel vulnerabilities on unmitigated
	  affected hardware.

	  If you are unsure how to answer this question, answer Y.

	  implementing dynamic MAC and Audit Policies.

	  If you are unsure how to answer this question, answer N.
