Problem IT02042
|
Status: Closed |
ABEND IN SQLAK_CALLBDRDAINPUT DUE TO MISALIGNED MEMORY ACCESS, LEADING TO SIGBUS SIGNAL |
| product: |
DB2 CONNECT / DB2CONNCT / 970 - DB2 |
| Problem description: |
A crash with a SIGBUS error in client side code may occur with
the following stack :
sqlak_callbDrdaInput
sqljrGenSqlDta
sqljrDrdaArCall
sqleuInvokeActivationRoutine
sqleuPerformServerActivationCheck
sqleUCappConnect
CLI_sqlConnect
SQLConnect2
The problems happens when DB2 accesses a 2 byte integer in a
non-2 byte aligned location.
Most platforms will handle this gracefully and perform a byte by
byte copy instead in the kernel but in some cases , this signal
may be passed to user code and trigger the SIGBUS signal causing
a failure in the process. |
