We also ensure that if the hook does not call bpf_bind(), the bound address is unmodified, and if the hook calls bpf_bind(), the bound address is exactly what we provided to the helper. A new netns is used to enable ping_group_range in the test without affecting ouside of the test, because by default, not even root is permitted to use unprivileged ICMP ping...
