RHEL7 still doesn't have this patch:
https://patchwork.ozlabs.org/patch/561746/
As test/workaround while that patch isn't out, please make that buffer
as big as your payload, even if you're going to use only one byte. It
will copy more but it's MSG_PEEK, it's not discarding/removing anything
from the queue anyway. It will probably work then.
