Fix Recommendation

Configure TOSS to enable hardening for the BPF JIT compiler by adding the following line to a file in the "/etc/sysctl.d" directory:

net.core.bpf_jit_harden = 2

The system configuration files need to be reloaded for the changes to take effect. To reload the contents of the files, run the following command:

$ sudo sysctl --system

Check Contents

Verify TOSS enables hardening for the BPF JIT with the following commands:

$ sudo sysctl net.core.bpf_jit_harden

net.core.bpf_jit_harden = 2

If the returned line does not have a value of "2", or a line is not returned, this is a finding.
