I have read many so questions and answers about this topic but I still don't have any idea why my program doesn't work.

My script:

a.c

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

   #include <linux/kernel.h>       /* Needed for KERN_INFO */

   #include <linux/init.h>         /* Needed for the macros */

   #include<linux/kmod.h>



   static int __init hello_start(void)

   {

       printk(KERN_INFO "Loading rooted module...n");

       char* argv = {"/home/tomasz/", "s.sh", NULL};



       static char* envp = { "HOME=/",  "TERM=linux",   "PATH=/sbin:/bin:/usr/sbin:/usr/bin", NULL };

       call_usermodehelper(argv[0], argv, envp, UMH_WAIT_EXEC);

       return 0;

   }



   static void __exit hello_end(void)

   {

       printk(KERN_INFO "exit.n");

   }



   module_init(hello_start);

   module_exit(hello_end);

/home/tomasz/s.sh

#for example

reboot

# but in the future here will be sending file by ftp

What am I doing wrong? Why doesn't script run?

Use /bin/bash as the executable and your script as the first argument:

char* argv = {"/bin/bash", "/home/tomasz/s.sh", NULL};

Use /bin/bash as the executable and your script as the first argument:

char* argv = {"/bin/bash", "/home/tomasz/s.sh", NULL};
