Problem IC75030
|
Status: Closed |
THE SQLOREAD FUNCTION DOESN'T HANDLE THE NULL BUFFER POINTER PROPERLY |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
The sqloread function doesn't handle the NULL buffer pointer
properly, which may eventually crash the instance with the
signal 11.
When the crash occurs, you may see the stacks of the crashing
agent as below:
?unknown
sqlbReadBlocks
sqlbDMSReadContainerData
sqlbDMSMapAndRead
sqlbDMSDirectRead
sqlbDirectRead
sqldx_diskread
sqldxReadLobData
sqldxReadLob
sqldx_lob_read
sqldFetchLFD
sqlriglf
sqlrimso
sqlriWriteCsoIntoBuffer
sqlriExtDtaGetNextChunk
sqlrrProcessGetNextChunk
sqlrrGetNextChunk
sqljs_ddm_getnxtchk
sqljsParseRdbAccessed
...
Where the top function "?unknown" should actually be resolved to
the os function memcpy. |
