Otherwise it is impossible to use it for something else, as it will break
userspace that puts garbage there.
The same check should be done in other structures, but the fact that
data in reserved fields is ignored is already part of the kernel ABI.

The ioctl command is read/write (or just read, if the fact that user space
writes n_samples field is ignored).

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.

Hello.
This patch set adds ability to set default values for
kernel.unprivileged_bpf_disable, net.core.bpf_jit_harden,
net.core.bpf_jit_kallsyms sysctl knobs as well as option to override
them via a boot-time kernel parameter.
