Problem summary

• APAR NUMBER:  PJ40684
  PRODUCT:  z/TPF
  FUNCTIONAL AREA:  TPFAR SQLAM SQL HANDLER
  SHIPPED IN PUT:  10
  
  ABSTRACT:
  An OPR-4 dump may result from TPFAR if the user ID or password
  fields specified using the ZSQLD command contain eight
  characters.
  
  PACKAGE CONTENTS:
  Source Segments:
  (C) base/rt/ar/crdk.c
  
  Object Only Binaries:
  None.
  
  Configuration Independent Binaries:
  (C) base/load/CRDA.so

  (C) base/obj/crdk.o
  
  Support Files:
  base/lst/crdk.lst
  base/lst/CRDA.map
  base/lst/CREA.map
  
  OTHER BINARIES TO BUILD: NO
  None.
  
  COMMENTS:
  When an application attempts to connect to a remote database
  using TCP/IP, a user id and optional password are specified.
  The user id and password were specified using the ZSQLD ADD
  command. When an applications attempts to connect to the
  database, TPFAR segment crdk.c builds the variables to send to
  the remote database. The exact size of the user id and password
  fields are passed to DB2. To compute this size, the string
  function strlen() is used passing as an argument a character
  array of eight elements. If less than eight alphanumeric
  characters are passed as input, the strlen() function computes
  the correct size since the array got initialized and will
  therefore be null terminated. If exactly eight characters are
  specified, the maximum number of characters, the strlen()
  function will continue to search for a null terminator passed
  the end of the supplied field. Depending upon what data is
  contained after these fields, the correct size may be used, an
  incorrect size may be used or an OPR-4 dump may result.
  

Problem conclusion

• SOLUTION:
  TPFAR segment crdk.c has been modified to not always use the
  strlen() function to compute the size of the user id and
  password fields. If the maximum number of characters is passed
  for either field, the sizeof() function is used to compute the
  size.
