IV21591: WMQ7.1 FIRST BLANK CHARACTER REPLACED BY X'00' AT END OF CONNECTIONNAME FIELD IN MQ CHANNEL DEFINITION (MQCD)

WebSphere MQ V7.5 Fix Pack 7.5.0.1
Fix Pack 7.1.0.3 for WebSphere MQ V7.1

APAR status

• Closed as program error.

Error description

• Customer uses a channel security exit and checks the value
  of the IPaddress in MQCD_CONNECTIONNAME field against
  a value entered in SCYDATA field of channeldefiniton.
  When running V7.0.1 the MQCD_CONNECTIONNAME field
  contains  the IPaddress followed by blanks.
  In WMQ V7.1 the first blank character after the IPadress
  in MQCD CONNECTIONNAME is replaced by x'00' ..
  The same applies for field MQCD_SHORTCONNECTIONNAME.
  .
  The code between VMQ V7.0.1 and  WMQ V7.1 has been
  rewritten to support the new CHLAUTH facility.
  In WMQ V7.1 we use function cciTcpGetPeerName which fills
  the Peername and we call function zapBlankStrip which
  replace the first blank character by x'00' at end of the
  CONNECTIONNAME.
  This was not done in WMQ V7.0.1.
  .
  Having x'00' appended to the CONNECTIONNAME causes problems
  for the customer's security exit as it wasn't originally
  coded to take this into account
  

Local fix

• Modify the channel exit to take care of the x'00' byte
  appended at end of connectionname
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using Channel security exits and using the connection name
  field may see a null character (x'00') rather than it being
  blank padded.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  Channel connection name field was erroneously null terminated.
  

Problem conclusion

• Code has been modified to blank pad the field before it is
  passed to any security exit.
