In these types of cases I usually use KASAN, or HW Breakpoint. with HW Breakpoint you can set an alert to monitor any read or write operation on some memory location. Check samples/hw_breakpoint/data_breakpoint.c for an example of breakpoints. KASAN can give you stacktraces when illegal memory access is done. Hope it helps. -- Regards Sudip _______________________________________________ Kernelnewbies mailing list [email protected] https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
