create_module - create a loadable module entry
#include <linux/module.h>
caddr_t create_module(const char *name, size_t size);
Note: No declaration
of this function is provided in glibc headers; see NOTES.
Note:
This system call is present only in kernels before Linux 2.6.
create_module()
attempts to create a loadable module entry and reserve the kernel memory
that will be needed to hold the module. This system call requires privilege.
On success, returns the kernel address at which the module
will reside. On error, -1 is returned and errno is set appropriately.
- EEXIST
- A module by that name already exists.
- EFAULT
- name is outside the program’s
accessible address space.
- EINVAL
- The requested size is too small even for
the module header information.
- ENOMEM
- The kernel could not allocate a contiguous
block of memory large enough for the module.
- ENOSYS
- create_module() is not
supported in this version of the kernel (e.g., the kernel is version 2.6 or
later).
- EPERM
- The caller was not privileged (did not have the CAP_SYS_MODULE
capability).
This system call is present on Linux only up until
kernel 2.4; it was removed in Linux 2.6.
create_module() is
Linux-specific.
The create_module() system call is not supported by
glibc. No declaration is provided in glibc headers, but, through a quirk
of history, glibc does export an ABI for this system call. Therefore, in
order to employ this system call, it is sufficient to manually declare
the interface in your code; alternatively, you can invoke the system call
using syscall(2)
.
