This change makes the socket cookie generator as a global counter instead of per netns in order to fix cookie collisions for BPF use cases we ran into. See main patch #1 for more details. Given the change is small/trivial and fixes an issue we're seeing my preference would be net tree (though it cleanly applies to net-next as well). Went for net tree instead of bpf tree here given the main change is in net/core/sock_diag.c, but either way would be fine with me. Thanks a lot!
