kernel: bpf: Support for hardening against JIT spraying

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF Just-In-Time JIT compiler. The BPF JIT allocator reuses memory space, and when new code is written, an indirect jump into the new program can reuse a branch prediction left behind by an old program. This could allow an attacker to...
