          Platform: All

          Priority: P1
         Component: GDT SCSI
        AssignedTo: scsi_drivers-gdt-scsi at kernel-bugs.osdl.org
        ReportedBy: ettl.martin at gmx.de
        Regression: No


Hello,

i detected an overlapping data buffer at file
"linux-2.6.29.3/drivers/scsi/gdth_proc.c"
For detection, i used the static code analysis tool cppcheck. It prints the
following message:
[linux-2.6.29.3/drivers/scsi/gdth_proc.c:199]: (error) Overlapping data buffer
hrec

Take a loop at file gdth_proc.c at line 199:

            sprintf(hrec,"%s,%d", hrec, reserve_list[i]);

Here, hrec is used by iteself at the sprintf statement, this is dangerous!!!!

Best regards

Ettl Martin
