Are you sure this fix is correct ?

The cmsghdr structure, as its name suggest, is meant to be the "header
of a message", and that's why it has this zero-length array at the end,
to access the payload of the message. I am not sure what the
consequences are in this specific case, but do you have some
evidence/explanation that this is correct, beyond "it builds fine" ?

Best regards,

Thomas
