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.
Also it seems the test infra is not passing type through correctly when
testing unix_inet_redir_to_connected. Unfortunately, the simple fix
also caused some CI tests to fail so investigating that now.
v3: drop unnecessary assignment (Martin) and rebase on latest selftests.
v2: drop changes to dgram side its fine per Jakub's point it graps a
reference on the peer socket from each sendmsg.
John Fastabend (2):
bpf: sockmap, af_unix stream sockets need to hold ref for pair sock
bpf: sockmap, add af_unix test with both sockets in map
