23-Aug-2021: Finding bugs related to memory errors in Linux Kernel
Submitted by Vadim Mutilin on Mon, 23/08/2021 - 16:31Nadezda Lutovinova has finished the GSoC 2021 project “Finding bugs related to memory errors in Linux Kernel and improving environment model specifications for static verification”. Her project was related to finding memory errors in Linux drivers code. During the work Nadezda has used Klever - a software verification framework that is created for automated checking of programs developed in the C programming language. It was used to analyze the Linux kernel version 5.12-rc3 code.
20-Aug-2021: Analysis & Fixing of Race Condition Warnings in the Linux Kernel
Submitted by Vadim Mutilin on Fri, 20/08/2021 - 07:22Saubhik Mukherjee has finished the GSoC 2021 Project "LSB: Analysis & Fixing of Race Condition Warnings in the Linux Kernel" for The Linux Foundation. The task is to catch bugs due to race conditions in Linux kernel 5.4 device drivers. A software verification framework called Klever automates the verification against a concurrency safety requirement specification. Using the Klever web interface, the generated error traces are analyzed and classified as false warnings or real bugs.

28-Aug-2020: Analysis and fixing of race condition warnings in the Linux kernel
Submitted by Vadim Mutilin on Fri, 28/08/2020 - 10:32Madhuparna Bhowmik has finished the GSoC 2020 Project “Analysis and fixing of race condition warnings in the Linux kernel” for The Linux Foundation. The project involved using Klever interface for finding the race condition related bugs in the v4.18 of the Linux Kernel, and most of them were still present in the latest kernel release which is v5.9. Out of the 301 traces analyzed around 44 of them were either Actual Bugs or Benign bugs. This gives a true positive rate of 14.6%.
