Hello!
I found a bug in module-init-tools.
'lsmod' shows a wrong module name, when module name complied with some
"define" at one of kernel header files.
For example,
File "current.c"
=======================
#include <linux/kernel.h>
#include <linux/module.h>
int init_module(void) {
return 0;
}
void cleanup_module() {
}
MODULE_LICENSE("GPL");
=======================
Makefile:
=======================
obj-m += current.o
=======================
Make this module and type commands:
insmod current.ko
lsmod
And we can see:
Module Size Used by
get_current() 1152 0 <---- Oops, must be 'current'
smbfs 61432 2
hfsplus 56708 0
nls_cp866 5120 1
nls_iso8859_1 4096 0
nls_cp437 5760 0
vfat 12800 0
fat 37916 1 vfat
nls_utf8 2048 1
.....
File <asm/current.h>:
===================
...
#define current get_current()
...
===================
Try to remove module:
romanu:/current # rmmod current
ERROR: Module current does not exist in /proc/modules
romanu:/current # rmmod -v "get_current()"
rmmod get_current(), wait=no
romanu:/current #
I can't remove module with 'rmmod current',
but can with
rmmod "get_current()"
Is it a bug?
Then, next example.
File 'init_stack.c'
=================
#include <linux/kernel.h>
#include <linux/module.h>
int init_module(void) {
return 0;
}
void cleanup_module() {
}
MODULE_LICENSE("GPL");
=================
Make and insert module 'init_stack.ko':
lsmod:
Module Size Used by
get_current() 1152 0
(init_thread_union.stack) 1152 0 <---- Oops, must be 'init_stack'
smbfs 61432 2
hfsplus 56708 0
nls_cp866 5120 1
nls_iso8859_1 4096 0
Now I can't to remove it at all ! :(:(
>From <asm/thread_info.h>
====================
...
#define init_stack (init_thread_union.stack)
...
====================
