Booting Fedora with Secure Boot enabled will result in Lockdown being enabled at boot
time. This will completly disable the BPF system call for all users .
Unfortunately, this breaks the IPAddressAllow & IPAddressDeny systemd feature
I don't have a solution for this, but as far as I understand, this will also prevent
other BPF use-cases (for example: Cilium on Fedora CoreOS).
