DLKM Module fails to load.

[Anil Kumar_5]

Hi,
When i try to load the module, i am getting the following Errors.

Overrun of module DLT or long branch stub table for module /stand/dlkm/mod.d/swspData.

Relocation in module /stand/dlkm/mod.d/swspData failed

Attempt to load unregistered module


Can somebody please let me know how i could solve this problem.

Thanks & regards,
Anil

Anil,

Normally this is hard to hit because the buffer is initially aligned
on a page boundary which means that there is usually some space for
overflow data. But if the size of the image calculated in the first
part happens to be very close to a page (4090 bytes, for example),
then there wonâ t be enough room and the buffer will overflow.

The overflow normally clobbers the allocatorâ s bookkeeping pointer
the next buffer, so we end up referencing a bad pointer when that
other memory is freed.

Hi,
Thanks a lot for the information, Do you suggest any workaround or fix for these kind of problems.
I have the the DLKM cumulative patch PHCO_22899 already installed on the system, which actually adress this problem. But not sure why i am still getting this problem.

Thanks & regards,
Anil

Hi Shine,

This is what i could get from the attaced document.

[PHCO_14664/PACHRDME/English] :
Some large modules fail to load with the following
error message: "Overrun of module DLT or long branch stub table for module."

This is the Error message i got when I tried to load the module. But as i mentioned earlier. The system is already installed with this patch.

Is there some thing i am missing in interpreting the document ?

Thanks & regards,
Anil

Hi,
Looks like the Patch is installed and the state is shown as configured.


PHCO_22899.CORE-KRN configured applied

Thanks & regards,

this is almost a shot in the dark, if at all you think its worth a try: as i understand,when building shared libraries, this problem is overcome by using +Z instead of +z in the compile line. im not sure if kernel modules are compiled PIC: if they are - if you are already using the compiler's +z option - you can try this out : use +Z instead of +z.

Hi,
Actually the problem ie there only when we try to install the module on one particular system. It has been working on many other customer system.
Hence i am not sure whether this will work.

Thanks & regards,

Hi. I'm seeing this same "Overrun of module DLT..." error on one of my 11.11 systems. Oddly, I've successfully built and loaded this particular DKLM on this machine in the past.

Anyway, the PHCO_22899 DKLM patch appears to be for 11.00 so I can't install it on this machine (presumably, it's already part of the 11.11 product?).

Did you ever solve your problem?

Thanks.
