Our objective in this chapter is to introduce the basics of Linux device drivers. We’ll begin with the concept of installable kernel modules. Then we’ll look at the basic device driver APIs in the ...

Resources Rubini, Alessandro, Jonathan Corbet, and Greg Kroah-Hartman, Linux Device Drivers, third Ed. , O’Reilly, 2005. On the one hand, this is a very readable and thorough treatment of kernel-level ...

This includes such things as whenever an inode is accessed, a module is loaded or a task is created. As of the 2.5.31 kernel, there were 88 different function pointers needed. The majority of these ...

The kernel, however, including modules, has no such restriction. That can make debugging modules tricky because you can easily bring the system to its knees.

When you program in the kernel, there is no operating system to step in and safely stop your code from running and tell you that you have a problem. The Linux kernel is pretty nice to its own code.

What superpowers? eBPF gives you the power to run programs in the Linux kernel without changing the kernel source code or adding additional modules. In effect, it acts as a lightweight (VM) inside ...

The Linux kernel is a monolithic kernel. It’s mainly one large program, but it closely interacts with other, distinct, programs such as drivers and kernel modules.

The OP is talking about mucking about in the kernel. Even if that book did talk about kernel programming, Stevens has been dead for 15-20 years so the book would be horribly out of date.

New Linux kernel "lockdown" module to limit high-privileged users -- even root -- from tampering with some kernel functionality.
