[Bug nss/18991] New: nss_files skips large entry in database


https://sourceware.org/bugzilla/show_bug.cgi?id=18991

            Bug ID: 18991
           Summary: nss_files skips large entry in database
           Product: glibc
           Version: 2.22
            Status: NEW
          Severity: normal
          Priority: P2
         Component: nss
          Assignee: unassigned at sourceware dot org
          Reporter: schwab@linux-m68k.org
            Blocks: 18007
  Target Milestone: ---

If the nss_files getent method returns unsucessful due to the entry being too
large it doesn't reread the entry on the next call.  This is a regression
introduced by commit b13b96c ("Separate internal state between getXXent and
getXXbyYY NSS calls").
