2023-11-10Kernel: Remove old dead codeAnton Kling
2023-11-10Kernel/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.
2023-11-09Kernel/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.

2023-11-09Kernel: Initalize the file descriptor pointers in the proess struct toAnton Kling
zero.
2023-11-08Kerenl/MMU: Remove dumb bug as a result of uninitalized memoryAnton 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.
2023-11-08Kernel/MMU: Detect system memory and dynamically adjust memory usage availableAnton Kling
Previously this would be hardcoded but now it can be detected by the bootloader and passed in via the multiboot header.

2023-11-08Kernel/MMU: Create a seperate table for heap allocationAnton Kling
2023-11-01Kernel: Add a simple TCP implementationAnton Kling
2023-10-31Kernel: Remove all O0 optimizations on functions.Anton Kling
The kernel can now fully compile under O3 without any noticable problems :)
2023-10-31Kernel: Bug fix, infinite loop when checking string memory permissionsAnton Kling
If the string is pointed to a very exact location in memory the loop never finishes.
2023-10-31Meta: Create simple build scripts for kernel, userland and general enviromentAnton Kling
2023-10-31Meta: 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.
