Overriding System Calls
Hello experts,
We are trying to override the system call in Linux.
We have downloaded the sample code from this location
http://www.faqs.org/docs/kernel/x931.html
We are giving
gcc -c -O2 -DMODULE -D__KERNEL__ syscall.c -I
/lib/modules/2.4.20-8/build/include
as a command to compile this source code.
It compiles without giving any error.
But when we insmod this module,it gives just one error as
[root@localhost root]# insmod syscall.o
syscall.o: unresolved symbol sys_call_table
Where are we going wrong?
Thanks in advance.
