2024-03-21	libc: fix malloc implementation	Anton Kling
	I don't know what was wrong but memory allocations were failing. I removed the old code and replaced it with the malloc implementation which exists in the kernel. Now it doesn't crash so I guess it is fine ¯\_(ツ)_/¯
2024-03-20	MMU: Fixed massive problem in assumption of RAM layout	Anton Kling
	This caused certain addreses which where not RAM memory to be assigned to virtual addresses incorrectly. This caused a significant slowdown when running it with KVM due to constantly having to exit the VM if the OS writes to memory that is not RAM. This fix increased the performance of KVM significantly and improved TCG performance.

2024-03-14	random changes made	Anton Kling

2024-03-02	Kernel: Fix incorrect hardcoded value.	Anton Kling
	It should be 20 as there are 5 addresses pushed onto the stack. Not hex 20 which is sligthly more and as a result caused random crashes.
2024-02-28	TCP/UDP: Start rewrite of network sockets	Anton Kling
	Having sockets be file descriptors seems like a bad idea so I trying to make UDP and TCP sockets be more independent and not be abstracted away as much.
2024-02-25	IPC: Inform the scheduler the process is waiting for a IPC message	Anton Kling

2024-02-22	Kernel: Fix undefined behavior and cleanup functions.	Anton Kling
	The int_syscall caused crashes for higher level of optimizations. To fix this I rewrote the function in assembly as I deemed it to be simpler.
2024-02-21	Kernel: Remove all inline assembly.	Anton Kling
	Now the kernel does not rely upon inline assembly which is often very error prone. This also means that the kernel could probably be compiled with any c99 compiler which would help future bootstrapping.
2024-02-21	Kerenel: Cleanup halt checking code	Anton Kling

2024-02-21	New clang-format options	Anton Kling

2024-02-19	Kernel: Change timing for context switches	Anton Kling

2024-02-19	Kernel/VFS: Cleanup of file descriptor halts	Anton Kling

2024-02-17	cleanup	Anton Kling

2024-02-16	General cleanup	Anton Kling

2024-02-14	Kernel: Update signal handling and IPC	Anton Kling

2024-02-09	Kernel/Interrupts: Restructure how interrupts are handeled in the kernel	Anton Kling
	Now all interrupts go through a common stub which will make certain signal handlers easier to implement
2024-02-07	Minor fix	Anton Kling

2024-02-07	Kernel: poll() should skip invalid file descriptors	Anton Kling

2024-02-07	Remove sti and cli inline assembly	Anton Kling

2024-02-07	Add enable/disable interrupts function	Anton Kling
	This is to reduce usage of inline assembly
2024-02-07	A lot of small changes	Anton Kling

2023-12-18	Add untracked files	Anton Kling

2023-11-29	Kernel: Zero initialize process struct during creation	Anton Kling

2023-11-28	Meta: Apply new clang-format rules to kernel	Anton Kling

2023-11-28	Kernel: Add basic IPC and move to microkernel design.	Anton Kling
	The IPC design is currently a WIP and is nowhere near complete
2023-11-25	Kernel: Add stat syscall	Anton Kling
	forgot to add it before
2023-11-25	Minibox shell: Change shell prompt to use cwd	Anton Kling

2023-11-24	LibC: Fill new allocations with random data and fix a bug	Anton Kling
	The bug was noticed as a result of this new randomization of allocations.
2023-11-24	Refactor write() and pwrite()	Anton Kling

2023-11-24	Refactor open()	Anton Kling

2023-11-23	Kernel/LibC: Add randomfill() syscall.	Anton Kling
	This syscall aims to fill the given buffer with cryptographically secure random data. If the syscall returns and does not cause a page fault it will always have filled the buffer with random data and never gives back any error value.
2023-11-23	LibC: Move assembly to its own file to avoid using inline	Anton Kling
	This was a ugly hack and in this case it caused undefined behavior.
2023-11-23	LibC: Reduce warnings in code	Anton Kling

2023-11-22	Networking: Split network packets if they are too large	Anton Kling

2023-11-22	Test: Add test case for realpath()	Anton Kling

2023-11-22	LibC: Add fflush() and buffer writes to file descriptors	Anton Kling

2023-11-22	Meta: Use dirent as a general include file	Anton Kling
	This include file is shared by the kernel and libc
2023-11-22	Kernel/RTL8139/Networking fixes	Anton Kling
	This is just a commit containing multiple fixes since I am too lazy to split them up.
2023-11-22	Kernel/LibC: Change file type detection	Anton Kling

2023-11-22	Meta: Cleanup of header files such that they are partially shared	Anton Kling
	The /include directory contains definitons that both the kernel and libc need to be in sync.
2023-11-21	Kernel: Make poll() return number of file descriptors that had revent set	Anton Kling

2023-11-20	LibC: Add ntohs and ntohl	Anton Kling

2023-11-20	LibC: Add macros for stdin, stdout, stderr in unistd	Anton Kling

2023-11-20	LibC: Allow open to accept multiple arguments	Anton Kling

2023-11-20	LibC: Add macros for file regnition	Anton Kling

2023-11-18	VFS: Do not add extra '/' on root path.	Anton Kling

2023-11-18	WindowServer: Implement window resizing.	Anton Kling
	Currently no event is sent to a client that a window is resized. This should be added when I can bother adding that functionality to the client applications also.
2023-11-17	Minibox: Add a somewhat improved shell	Anton Kling
	This shell actually lexes and produces a AST which makes it easier to add features and will makes it more difficult to introduce bugs. So basically it is just better code.
