--- Comment #11 from Allan Jude <allanjude at FreeBSD.org> ---
(In reply to chris.torek from comment #10)
Users are reporting failures on FreeNAS 9.10 that were traced back to your
patch offered here.

This simple test program:

http://pastebin.ca/3755236

sends an FD between a child and a parent

In the process, the SCM_RIGHTS is lost, and recvmsg returns a message with
SCM_CREDS instead.
