Hi,
I am writing a code which invokes the init_module system call. At the system call the program terminates with a segmentation fault and error "Invalid operand: 0000".
The first parameter to init_module is the module name which is a constant, so I guess the problem is with the second parameter which is a pointer to struct module. Following are the values of the elements of struct module:
sizeof_struct = 96
name is not NULL
size = 512
flags = 0
nsyms = 3
ndeps = 0
syms is not NULL
deps is NULL
init is not NULL
cleanup is not NULL
ex_table_start is NULL
ex_table_end is NULL
name is not NULL
size = 512
flags = 0
nsyms = 3
ndeps = 0
syms is not NULL
deps is NULL
init is not NULL
cleanup is not NULL
ex_table_start is NULL
ex_table_end is NULL
So deps, ex_table_start and ex_table_end are NULL. Rest all seem to be fine. Also when I do lsmod, the module seems to have loaded with use count 1 and (Initializing) displayed next to it.
IS this due to the NULL value of the above 3 parameters ? Also is there a way to debug the code when it enters init_module ?
Thanks for the help,
SP
