            Bug ID: 212122
           Summary: getaddrinfo doesn't implement sort rule 10
                    deterministically
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: Herbie.Robinson@stratus.com

The formal behavior of qsort is unstable with regard to objects that are eq=
ual.
 Unfortunately, the standard requires that otherwise equal objects remain in
the order supplied by the DNS server.  The present code attempts to deal wi=
th
this by returning -1 for objects that are equal (i.e., returns that the fir=
st
parameter is less then the second parameter).  Unfortunately, the qsort API
does not state that the first parameter passed in is in any particular posi=
tion
in the list.

Assuming I can get it uploaded, the patch I have for it will be against
Revision 304034.

Again, while this affects a lot or people, I don't think many will notice.=

It's been this way for years and I only just noticed...
