Subject: [PATCH net 0/2] Fix collisions in socket cookie generation

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!

  sock: make cookie generation global instead of per netns
  bpf: sync bpf.h to tools infrastructure
