kCFI is a tool that enables the compilation of commodity Operating Systems with Control-Flow Integrity protection. kCFI first prototype was developed/implemented during a PhD program held in the University of Campinas, in Brazil. Although fully functional, the tool remains in a very experimental shape, needing to be refactored prior to being released. As kCFI consists in multiple tools, which include compiler plugins, kernel patches and binary analyzers, its deployment is considerably complex. Once code refactoring is finished, the next step consists in setting up proper repositories for the tool and for each submodule, along with scripts and documentation to enable easy configuration and compilation on new environments.

Everything is (in) a module now. They depend on each other and you need a whiteboard and a few different colors to understand and remember how.

There seems to be an overall consensus that the ioctl interface used by ethtool is a poor design as it's inflexible, error prone and notoriously hard to extend. It should clearly be replaced by netlink and obsoleted. Unfortunately not much actual work has been done in that direction until this project started. The project started in Hackweek 16 (fall 2017) and has been worked on since, both in Hackweek 17-19 and outside. First two parts of kernel implementation are in mainline since 5.6-rc1, first part of userspace implementation (ethtool utility) has been submitted to upstream at the end of Hackweek 19 (2020-02-16).

1% of SUSE Manager's functionality in 0.1% of the lines of code

Let's create a much simpler SUSE Manager — one you could use at home! Users should be able to deploy and operate in minutes with minimal configuration, while still retaining the very core features that make SUSE Manager useful!

Most large workloads such as SAP HANA require special, highly optimized configuration to run in a virtual machine. Virtual resources such as memory and CPU must be carefully configured to ensure optimum performance of the virtual machine workload. Default VM configuration created by tools such as virt-install are not optimized and often result in poor performance of large workloads due to memory access latencies and incorrect/incomplete information available to the VM's task scheduler. Currently, users deploying large workloads must manually optimize virtual CPU and memory resources, which can be error-prone and if not done properly can actually degrade performance. This project aims to create a tool that can produce suggested vCPU and vNUMA configuration based on a VM configuration template and capabilities of the target virtual machine host. E.g. something along the lines of

Behavior-Driven Development is a process to follow in software development. I want to learn how BDD testing framework works. Learn how the pieces fall together and how frameworks are put together, as well as best practice of BDD.

I want to experiment with three things: * Blockchain
