I wrote following program in my home directory.


#include <linux/kernel.h>
#include <sys/syscall.h>
#include <linux/module.h>
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
{
printk("Sys_exit called with err_code=%d\n",err_code);
return main_sys_exit(err_code);
}

int init_module()
{
main_sys_exit=sys_table[__NR_exit];
sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{
sys_table[__NR_exit]=main_sys_exit;
}
~

When I compiled it as


gcc -Wall -DMODULE -D__KERNEL__ -DLINUX -c sample2.c

I got following error


sample2.c:3:26: error: linux/module.h: No such file or directory
sample2.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘int’

sample2.c:15: warning: control reaches end of non-void function
sample2.c: In function ‘cleanup_module’:
sample2.c:18: error: ‘main_sys_exit’ undeclared (first use in this function)


What is the above error and why is it coming?
I did all this in my home directory.

You need to install the headers for your kernel.


sudo apt-get install linux-headers-generic

I looked at man page of gcc and searched for
DMODULE D__KERNEL and DLINUX got following

I had missed one line of code from the link I gave

following is new program


#include <linux/kernel.h>
#include <sys/syscall.h>
#include <linux/module.h>
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)
{
printk("Sys_exit called with err_code=%d\n",err_code);
return main_sys_exit(err_code);
}

int init_module()
{
main_sys_exit=sys_table[__NR_exit];
sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{
sys_table[__NR_exit]=main_sys_exit;
}

Now see I think it is easy to tell now as what is the error.
Also
as some one pointed out about linux/module.h

I did a find on module.h

What is the above error and why is it coming?

The compiler errors are occurring because you are building the kernel module incorrectly. You do not build kernel modules in the same fashion as you do regular applications.

What you need is a Makefile to build the module.
For the Makefile:


obj-m := sample2.o

KDIR := /lib/modules/$(shell uname -r)/build

all:
$(MAKE) -C $(KDIR) M=$(PWD) modules

clean:
$(MAKE) -C $(KDIR) M=$(PWD) clean
tapas_mishra
August 21st, 2010, 05:33 AM
I wrote another module Makefile as follows


obj-m+=hello.o
all:
make -C /lib/modules/$(uname -r)/build/M=$(PWD) modules
clean:
make -C /lib/modules/$(uname -r)/build/M=$(PWD) clean
clean-files:=Module.symvers
for the hello world kernel module
the program is


#include <linux/init.h>
#include <linux/module.h>
MODULE_LICENSE("Dual BSD/GPL");
static int hello_init(void)
{
printk(KERN_ALERT "Hello,world tapas\n");
return 0;
}
static void hello_exit(void)
{
printk(KERN_ALERT "Good Bye,cruel world\n");
}
module_init(hello_init);
module_exit(hello_exit);

The code which is giving me error is on this link (https://docs.google.com/fileview?id=0B2A4urYOAf6POTI1OGE1MjctM2UyMC00OGUzL ThlNDUtZDBhOWFjY2Y1MDUz&hl=en)
Page 48 left hand side column.


I also tried

gcc -I /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/ -I /usr/src/linux-headers-2.6.28-11/include/linux/ -c sample2.c


Got following error


sample2.c:3:26: error: linux/module.h: No such file or directory
sample2.c:5: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘int’
sample2.c:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘int’

sample2.c: In function ‘cleanup_module’:

What more should I try?

This is the link (http://techblog.aasisvinayak.com/a-voyage-to-kernel-first-24-parts/) from where I am trying these programs.
The author has shared his articles here. (https://docs.google.com/fileview?id=0B2A4urYOAf6POTI1OGE1MjctM2UyMC00OGUzL ThlNDUtZDBhOWFjY2Y1MDUz&hl=en)You do not need to login to gmail to access any of those docs.Page 48 12th day is what I am trying.
This is the program


#include <linux/kernel.h>
#include <sys/syscall.h>
#include <linux/module.h>
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)
{
printk("Sys_exit called with err_code=%d\n",err_code);
return main_sys_exit(err_code);
}

int init_module()
{
main_sys_exit=sys_table[__NR_ exit];
sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{
sys_table[__NR_exit]=main_sys_exit;

}

To compile it I have tried

Step1) gcc -Wall -DMODULE -D__KERNEL__ -DLINUX -c sample2.c
Step2) added -I to gcc flag
gcc -Wall -DMODULE -D__KERNEL -DLINUX -I
/usr/src/linux-headers-2.6.28- 11/include/ -c sample2.c

Step3) added one more -I with asm in path
gcc -I /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/ -I
/usr/src/linux-headers-2.6.28-11/include/ -c sample2.c

Step4) added asm/x86/include in path
gcc -I /usr/src/linux-headers-2.6.28-11/arch/x86/include/ -I
/usr/src/linux-headers-2.6.28-11/include/ -c sample2.c

Step5) added linux in -I of second argument
gcc -I /usr/src/linux-headers-2.6.28-11/arch/x86/include/asm/ -I
/usr/src/linux-headers-2.6.28-11/include/linux/ -c sample2.c

Step6) removed asm from first argument and linux from second
gcc -I /usr/src/linux-headers-2.6.28-11/arch/x86/include/ -I
/usr/src/linux-headers-2.6.28-11/include/ -c sample2.c

All these attempts have failed.
Any guesses?

Any guesses?

Read the attached PDF file for more enlightenment...

P.S. You will need to download and then uncompress the file before you can peruse it.

I have read it but I tried a Makefile



obj-m += sample2.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean

The above Makefile worked with some warning.


make -C /lib/modules/2.6.28-11-generic/build M=/home/tapas/exer modules

LD [M] /home/tapas/exer/sample21.ko

but the method of gcc has not worked.
Where as the program given in the link I gave is


#include <linux/kernel.h>
#include <linux/module.h>
#include <sys/syscall.h>
extern void *sys_table[];
asmlinkage int(*main_sys_exit)(int);
asmlinkage int alt_exit_function(int err_code)
{
printk("Sys_exit called with err_code=%d\n",err_code);
return main_sys_exit(err_code);
}

int init_module()
{
main_sys_exit=sys_table[__NR_exit];
sys_table[__NR_exit]=alt_exit_function;
}
void cleanup_module()
{
sys_table[__NR_exit]=main_sys_exit;
}

I have tried


the Makefile


obj-m += sample2.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules
clean:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) clean
also failed with following errors

make[1]: Leaving directory `/usr/src/linux-headers-2.6.28-11-generic'
make: *** [all] Error 2

also following approach of gcc

gcc -I /usr/src/linux-headers-`uname -r`/include -I /usr/src/linux-headers-`uname -r`/arch/x86/include/asm -I /usr/include -Wall -DMODULE -D__KERNEL__ -DLINUX -c samp\le2.c

The function init_module() needs to return a value; after all, you have declared it to return an int. Try returning 0.


static int __init init_module(void)
{
...

return 0;
}

And as for the other warning, from what I have read (last week), the sys_table[] is no longer accessible (hence not defined) in kernel versions 2.6.x. Maybe a security feature?

Pay careful attention to the documentation that you are referencing to develop your code since a lot changed between 2.4.x and 2.6.x of the Linux kernel.

The most basic of kernel module source code for 2.6.x kernels should look something like:


#include <linux/module.h> // Needed by all modules

#define DRIVER_AUTHOR "Your Name"
#define DRIVER_DESC "A Hello World kernel module."

MODULE_LICENSE("GPL");
MODULE_AUTHOR(DRIVER_AUTHOR); /* Who wrote this module? */
MODULE_DESCRIPTION(DRIVER_DESC); /* What does this module do */


static int __init hello_world(void)
{
printk("hello world\n");
return 0;
}

static void __exit goodbye_world(void)
{
printk("goodbye world\n");
}

module_init( hello_world );
module_exit( goodbye_world );

Your Makefile is correct.
