In our previous installment, the author introduced methods for accessing peripherals from user space in Linux. In this installment, Abbott describes kernel modules and device drivers followed by a ...

With this second excerpt, Abbott discusses kernel modules and device drivers in Part 1, Part 2, Part 3, Part 4, Part 5 and Part 6. In this final installment of the excerpt, Abbott continues this ...

This approach would allow different security models to work without modifying the main kernel code. Out of this discussion grew the Linux Security Module Project (LSM). A number of developers worked ...

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.

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.

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 ...

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.

Members of the open source community are working on a new security-focused project for the Linux kernel. Named Linux Kernel Runtime Guard (LKRG), this is a loadable kernel module that will perform ...

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