execve replacement.

[=?iso-8859-1?Q?Abel_Mu=F1oz_Alcaraz?=]

Hi everybody,

	I have replaced the execve() kernel API with my own implementation but it
doesn't work well.

		extern void * sys_call_table[]

		asmlinkage int (*system_execve)(const char *, const char **, const char
**);

		asmlinkage int my_execve(const char * filename, const char **argv, const
char **envp)
		{
			return system_execve(filename, argv, envp);
		}

		int init_module()
		{
			system_execve = sys_call_table[__NR_execve];
			sys_call_table[__NR_execve] = my_execve;
		}

		void cleanup_module()
		{
			sys_call_table[__NR_execve] = system_execve;
		}

	Does anybody know where is the problem?

Thanks in advance.

-Abel.
