--- Comment #2 from Jason A. Harmening <jah at FreeBSD.org> ---
It looks like the 32-bit kernel compat shim for recvmsg() isn't correctly
padding the data size for each control message to the required 4-byte alignment
when calculating controllen for the output header. I think the fix may be very
simple; the attached patch worked for me.
