[Bug network/19570] New: Implement random DNS server selection in the stub resolver


https://sourceware.org/bugzilla/show_bug.cgi?id=19570

            Bug ID: 19570
           Summary: Implement random DNS server selection in the stub
                    resolver
           Product: glibc
           Version: 2.24
            Status: NEW
          Severity: normal
          Priority: P2
         Component: network
          Assignee: unassigned at sourceware dot org
          Reporter: fweimer at redhat dot com
  Target Milestone: ---
             Flags: security-

To spread DNS query load with many short-lived processes, it is sensible to
select a random server for queries.  With short-lived processes, RES_ROTATE
does not always help to spread load because the name server order is still
deterministic.
