PH63515: SMF 116 TYPE 10 FIELD QCSTSLCS RETURNS 0 IF SSLCIPH IS SET AS AN ALIAS CIPHERSPEC (E.G. ANY*)

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Development finds that code in CSQXSMFT which sets the QCSTSLCS
  field tried to map the cipherspec in the channel definition
  (SSLCIPH) into a hex cipher. The smfSSL_CIPHER_TABLE table can
  then be used to decode this hex cipher back into a character
  cipher. The problem is that the code which sets QCSTSLCS does
  not account for the ANY* cipherspecs, which results in QCSTSLCS
  being left as 0.

  * PROBLEM DESCRIPTION: The QCSTSLCS field from SMF 116 returns *
  *                      0 for any alias CipherSpecs.            *
  ****************************************************************
  The code that sets the QCSTSLCS value retrieves the CipherSpec
  from the channel definition and uses the smfSSL_CIPHER_TABLE
  table to map the value (SSLCIPH) to its hex cipher. However,
  this table does not include alias CipherSpecs which leaves
  QCSTSLCS being set to 0 when a CipherSpec is in place.
  

Problem conclusion

• The code has been modified to use the negotiated CipherSpec from
  the channel status instead for the QCSTSLCS field when a
  CipherSpec has been set. If no CipherSpec is set in the channel
  status, the CipherSpec specified in the channel definition will
  be used instead.
