Subject: [PATCH net 0/2] bpf: fix verifier min/max handling in BPF_SUB

I managed to come up with a test for the swapped bounds in BPF_SUB, so here
 it is along with a patch that fixes it, separated out from my 'rewrite
 everything' series so it can go to -stable.

  bpf/verifier: fix min/max handling in BPF_SUB
