            Bug ID: 23973
           Summary: Concurrent use of ldconfig may clobber
                    /etc/ld.so.cache temporarily
           Product: glibc
           Version: 2.26
            Status: NEW
          Severity: normal
          Priority: P2
         Component: dynamic-link
          Assignee: unassigned at sourceware dot org
          Reporter: schwab@linux-m68k.org
  Target Milestone: ---

When two parallel runs of ldconfig write out the cache file the first process
may rename the temp file while the second one is still writing to it.  The name
of the temp file should be made unique to the process.
