IV21405: LUA RUI_WRITE RETURNS OK EVEN IF WRONG SNF SUPPLIED

Communications Server for AIX, Version 6.4 -- Latest PTFs

APAR status

• Closed as program error.

Error description

• Communications Server for AIX and Linux
  ---------------------------------------
  If an LUA program provides the wrong SNF in an RUI_WRITE for a
  response, the RUI_WRITE returns OK but the response is never
  sent.
  

Local fix

• Correct the program to provide the correct SNF.
  

Problem summary

• USERS AFFECTED: All programs using the LUA API.
  
  PROBLEM DESCRIPTION:
  If an LUA application issues an RUI_WRITE with an SNA +ve RSP
  with a sequence number field that does not  match an outstanding
  chain then the RUI_WRITE is accepted and no +ve RSP is sent to
  the mainframe.
  
  PROBLEM SUMMARY:
  Internal code is not properly rejecting the RUI_WRITE even
  though it is properly preventing the +ve response from being
  sent.
  

Problem conclusion

• The code has been altered to properly reject the RUI_WRITE with
  error codes:
  primary return code: LUA_UNSUCCESSFUL
  secondary return code: LUA_RSP_CORRELATION_ERROR
  

Temporary fix

• sna_v5router64
