From fa9dd599b4dae841924b022768354cfde9affecb Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Sat, 20 Jan 2018 01:24:33 +0100 Subject: bpf: get rid of pure_initcall dependency to enable jits Having a pure_initcall() callback just to permanently enable BPF JITs under CONFIG_BPF_JIT_ALWAYS_ON is unnecessary and could leave a small race window in future where JIT is still disabled on boot. Since we know about the setting at compilation time anyway, just initialize it properly there. Also consolidate all the individual bpf_jit_enable variables into a single one and move them under one location. Moreover, don't allow for setting unspecified garbage values on them.
