#gsoc#gsoc24#multiboot2#booting
In this blog post, I discuss the final weeks of my GSoC project, highlighting the process of testing Nuktiboot2 support on the helloworld and nginx applications, and reflecting on the progress made in enhancing the boot process.

This is the fourth post in a series of posts where I talk about my progress with the project.
#gsoc#gsoc24#allocators#synchronization
Different applications have different memory usage patterns and perform better
when using dedicated memory allocators. Right now, the buddy allocator is the only
available memory allocator used in Unikraft, so this GSoC project aims to
port more memory allocators to it, starting with mimalloc.

#gsoc#gsoc24#kraftkit
The goal of this project is to improve Unikraft's tooling, more especially, the kraft command-line tool, so that it can dynamically inject user-supplied variables into the build system.
#gsoc#gsoc24#uefi#booting
This project aims to add support for the modern UEFI GOP interface in Unikraft.
#gsoc#gsoc24#booting
The Linux boot protocol plays an important role in the initialization of the Linux operating system, emphasizing the importance of system optimization and scalability.
#gsoc#gsoc24#multiboot2#Booting
Multiboot2, an enhanced version of Multiboot, solves some of the limitations of the original protocol, such as the lack of support for 64-bit UEFI systems. It also provides a more accurate and detailed communication during the bootstrapping process and offers a standardized tag system for easier configuration.

The beauty of open source is the immediate availability of source code that
you can use to create or improve your software. Of course, this relies on
compatible licensing...

of familiarizing myself with Unikraft and an initial attempt to using
clang's ShadowCallStack, in this post, we will take a look into some
implementations that were tried in the meantime.
#gsoc#gsoc22
The previous blog on the SMP support explained different
synchronization primitives for the unikraft. As a part of the next

This project aims to add the SMP safe synchronization premitives as well as
remove the race conditions in the kernel.
#gsoc#gsoc22#security
While Unikraft provides great security advantages through strong
cross-application isolation, traditional means of securing one's
application shouldn't be overlooked.
