            Bug ID: 204890
           Summary: named pipes (FIFOs) not seen as such over NFS
           Product: Base System
           Version: 10.2-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs at FreeBSD.org
          Reporter: mi at FreeBSD.org

A named pipe created on an NFS-server is not seen as such on NFS-clients.

For example, I have a filesystem mounted as /green on an NFS-server (running
10.2-STABLE #0 r289145). After creating a FIFO there with mkfifo, I can see it
properly:

prw-r--r--  1 mi  wheel  0 Nov 29 00:05 /green/tmp/test

However, an NFS-client (running 10.2-STABLE FreeBSD 10.2-STABLE #0 r291365)
sees the same entry differently:

?rw-r--r--  1 mi  wheel  0 Nov 29 00:05 /green/tmp/test
(note the question mark for type...)

stat(1) demonstrates other differences:

NFS-server:
92 74636334 prw-r--r-- 1 mi wheel 0 0 "Nov 29 00:05:51 2015" "Nov 29 00:05:51
2015" "Nov 29 00:05:51 2015" "Nov 29 00:05:51 2015" 16384 0 0 /green/tmp/test

NFS-client:
973143811 74636334 ?rw-r--r-- 1 mi wheel 4294967295 0 "Nov 29 00:05:51 2015"
"Nov 29 00:05:51 2015" "Nov 29 00:05:51 2015" "Dec 31 18:59:59 1969" 16384 0 0
/green/tmp/test
