[PATCH 2/3] bpf: add ability to configure BPF JIT hardening via boot-time parameter

2018-05-21 Thread Eugene Syromiatnikov
This patch introduces two configuration options, BPF_JIT_HARDEN_BOOTPARAM and BPF_JIT_HARDEN_BOOTPARAM_VALUE, that allow configuring the initial value of net.core.bpf_jit_harden sysctl knob, which is useful for enforcing JIT hardening during the early boot. Signed-off-by: Eugene Syromiatnikov
