Subject: [PATCH bpf 0/2] sockmap fix for KASAN_VMALLOC and af_unix

The af_unix tests in sockmap_listen causes a splat from KASAN_VMALLOC.
Fix it here and include an extra test to catch case where both pairs
of the af_unix socket are included in a BPF sockmap.

John Fastabend (2):
  bpf: sockmap, af_unix sockets need to hold ref for pair sock
  bpf: sockmap, add af_unix test with both sockets in map
