Securing the Linux Kernel by patching even its smallest vulnerabilities is of high importance as these small things can cost a lot. One such area that is exploited regularly is a structure in read-write mode. According to my mentor Julia it is good to work on something small and focused…

For every patch sent for a Linux kernel driver one needs to be sure that the .o file has been obtained after compiling the changed .c file. A driver can contain a mixture of files that are meant for different machine architectures like blackfin, arm, sparc, mips, x86 etc. It…

Pointers in C/C++ have always confused people as they can be used in many ways and these ways can go really crazy sometimes. Understanding this topic is a bit complex initially but once you get hold of it you will appreciate how beautifully the concept of pointers work in C…

As mentioned in my previous blog my internship with the Linux Kernel is focused on the ways to make the kernel more secure. Adding const annotation to the structures is one of the ways to achieve this. Annotating a variable of any data type with ‘const’ implies that it becomes…

My Outreachy internship with the Linux Kernel revolves around the ways to make the kernel more secure from attacks that involves overwriting the memory regions allocated to the kernel code. One of the ways to protect the kernel from an attack is to make different parts of the kernel read-only…

Before starting my story I would like to introduce myself. My name is Bhumika Goyal and I am a 4th year student of B.tech in Computer Science and Engineering. This November I got an excellent opportunity to work as an Outreachy intern for the Linux kernel. …
