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) ... ====================
