Linux system calls never change. What, never? Hardly ever. One of the fundamental principles of Linux kernel development is that user-space interfaces are set in stone. Once an API has been made ...

If you’ve ever wondered how much memory a process uses, you’ve probably used a form of task manager or system monitor. System monitors can be useful to identify resource hogs, but are often less ...

There's an effort under way to reduce and ultimately remove all system call invocations from within kernel space. Dominik Brodowski was leading this effort, and he posted some patches to remove a lot ...

This new technical paper titled “AMD Prefetch Attacks through Power and Time” is from researchers at Graz University of Technology and CISPA Helmholtz Center for Information Security. Note, this is a ...

Here are the benefits and some caveats to running data-path applications in the user space. Discussed is Linux's UIO framework. Traditionally, packet-processing or data-path applications in Linux have ...

Mike Rapoport from IBM launched a bid to implement address space isolation in the Linux kernel. Address space isolation emanates from the idea of virtual memory—where the system maps all its hardware ...

(1) The memory allocated to applications in a computer that uses an operating system such as macOS or Linux. Such operating systems keep their kernel in one area of memory (kernel space) with user ...
