2023-11-13	Crypto: Implement fast insecure RNG for overwritting memory areas.	Anton Kling
	This is mainly done to test for uninitlalized memory and find bugs faster. Therefore it does not need to be cryptographically secure or perfectly uniform. Xoshiro256++ seems like a good fit.
2023-11-13	Kernel: Add typedefs.h	Anton Kling

2023-11-13	ARP: Save the IP, MAC of incoming ARP requests	Anton Kling

2023-11-13	Exceptions: Output CR2 on page fault	Anton Kling

2023-11-12	AHCI: Add very basic AHCI and some additional helper functions to mmu.c	Anton Kling
	Currently certain parts of the code are taken from osdev wiki as there seems to be very little documentation that I can find on how H2D FIS is structured. Those parts, especially some of the uglier parts of the example code will be rewritten/changed.
2023-11-12	Kernel/PCI: Add functions for getting BAR and specific PCI devices by	Anton Kling
	class
2023-11-10	Ext2: Change char* to u8* where the type is referencing data and not a C	Anton Kling
	string
2023-11-10	Kernel Style: Change uint_t -> u	Anton Kling

2023-11-10	Kernel/Memory: Fill new allocations with random data.	Anton Kling
	This should make it easier to spot uninitalized memory being used.
2023-11-10	Syscall: Cleanup code and remove dumb usage of get_vfs_fd.	Anton Kling

2023-11-10	Kernel: Remove old dead code	Anton Kling

2023-11-10	Kernel/fs: Dynamically allocate based upon file size.	Anton Kling
	This commit also changes "unsigned char" to "char". A slight step in the direction of making my coding style less bipolar.
2023-11-09	Kernel/fs: Dynamically allocate depending upon file size of directory.	Anton Kling
	This also solves a bug where the data_p pointer could get out of range due to incorrect assumptions being made about the ext2 directory layout. To be fair even a faulty ext2 directory layout should not be able to cause memory bugs.
2023-11-09	Kernel: Remove old comment	Anton Kling

2023-11-09	Kernel: Initalize the file descriptor pointers in the proess struct to	Anton Kling
	zero.
2023-11-08	Kerenl/MMU: Remove dumb bug as a result of uninitalized memory	Anton Kling
	The kernel would randomly crash. Turns out I did not zero out the frames so my page allocator seemed to get into some weird state.
2023-11-08	Kernel/MMU: Detect system memory and dynamically adjust memory usage available	Anton Kling
	Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header.

2023-11-08	Kernel/MMU: Create a seperate table for heap allocation	Anton Kling

2023-11-01	Kernel: Add a simple TCP implementation	Anton Kling

2023-10-31	Kernel: Remove all O0 optimizations on functions.	Anton Kling
	The kernel can now fully compile under O3 without any noticable problems :)
2023-10-31	Kernel: Bug fix, infinite loop when checking string memory permissions	Anton Kling
	If the string is pointed to a very exact location in memory the loop never finishes.
2023-10-31	Meta: Create simple build scripts for kernel, userland and general enviroment	Anton Kling

2023-10-31	Meta: Move kernel and userland to their own folders.	Anton Kling
	This is to allow both the kernel and the userland to share certain header files and to make the folder structure a bit more clear.
