When BPF JIT compiler is enabled, then compiled images are unknown addresses to the kernel, meaning they neither show up in traces nor in /proc/kallsyms. This enables export of these addresses, which can be used for debugging/tracing. If bpf_jit_harden is enabled, this feature is disabled.
Values :
- 0 - disable JIT kallsyms export (default value)
- 1 - enable JIT kallsyms export for privileged users only
