![]() ![]() Glibc does not seem to provide a C wrapper for them, so we just create our own with syscall. Access Linux Kernel Programming: A comprehensive guide to kernel internals, writing kernel modules, and kernel synchronization BY author Free Download Full Book > Download PDF Access. You will write a module that executes as a kernel-space extension of Linux to report the values of the kernels xtime variable. The param_values argument is as for init_module().įinit is newer and was added only in v3.8. It is useful when the authenticity of a kernel module can be determined from its location in the filesystem in cases where that is possible, the overhead of using cryptographically signed modules to determine the authenticity of a module can be avoided. The finit_module() system call is like init_module(), but reads the module to be loaded from the file descriptor fd. The Linux kernel offers two system calls for module insertion: We use the init_module / finit_module and remove_module Linux system calls. ![]() Tested on a QEMU + Buildroot VM and Ubuntu 16.04 host with this simple parameter printer module. Modify the Makefile to add the new module. Modify the KConfig to introduce the new module.
