2024-02-21New clang-format optionsAnton Kling
2024-02-19Kernel: Change timing for context switchesAnton Kling
2024-02-19Kernel/VFS: Cleanup of file descriptor haltsAnton Kling
2024-02-17cleanupAnton Kling
2024-02-16General cleanupAnton Kling
2024-02-14Kernel: Update signal handling and IPCAnton Kling
2024-02-09Kernel/Interrupts: Restructure how interrupts are handeled in the kernelAnton Kling
Now all interrupts go through a common stub which will make certain signal handlers easier to implement
2024-02-07Kernel: poll() should skip invalid file descriptorsAnton Kling
2024-02-07Remove sti and cli inline assemblyAnton Kling
2024-02-07Add enable/disable interrupts functionAnton Kling
This is to reduce usage of inline assembly
2024-02-07A lot of small changesAnton Kling
2023-11-29Kernel: Zero initialize process struct during creationAnton Kling
2023-11-28Meta: Apply new clang-format rules to kernelAnton Kling
2023-11-28Kernel: Add basic IPC and move to microkernel design.Anton Kling
The IPC design is currently a WIP and is nowhere near complete
2023-11-25Kernel: Add stat syscallAnton Kling
forgot to add it before
2023-11-24Refactor write() and pwrite()Anton Kling
2023-11-24Refactor open()Anton Kling
2023-11-23Kernel/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.
2023-11-22Networking: Split network packets if they are too largeAnton Kling
2023-11-22Meta: Use dirent as a general include fileAnton Kling
This include file is shared by the kernel and libc
2023-11-22Kernel/RTL8139/Networking fixesAnton Kling
This is just a commit containing multiple fixes since I am too lazy to split them up.
2023-11-22Meta: Cleanup of header files such that they are partially sharedAnton Kling
The /include directory contains definitons that both the kernel and libc need to be in sync.
2023-11-21Kernel: Make poll() return number of file descriptors that had revent setAnton Kling
2023-11-18VFS: Do not add extra '/' on root path.Anton Kling
2023-11-17Kernel: Add isatty syscallAnton Kling
2023-11-16VFS: Do canonicalization of the current working directoryAnton Kling
2023-11-16Kernel: Change how syscalls are built and implemented.Anton Kling
2023-11-16ext2: Fix directory resolutionAnton Kling
Previously a parsing of /usr/../ would fail as it would be searching '/' for a empty file even though the desired outcome if for it to stop parsing after reaching '/'. The solution is to give the current directory inode if the file searched for in the directory is empty.
2023-11-15Add untracked filesAnton Kling
2023-11-15VFS/LibC: Add getcwd()Anton Kling
2023-11-15Meta: Setup a drive over AHCIAnton Kling
2023-11-15PCI: Add interrupt handler functionsAnton Kling
2023-11-15Kernel/LibC: Add chdir function and syscallAnton Kling
2023-11-15VFS: Add statAnton Kling
2023-11-15VFS: Bug fix. Uninitalized structure member.Anton Kling
This was found thanks to kmalloc now filling new allocations with random data.
2023-11-15ext2: Bug fix. Add padding to the block group descriptor.Anton Kling
2023-11-13AHCI: Add write function.Anton Kling
This also changes the ext2 filesystem so it will now write to the file it mounted. Currently the file mounted is /dev/sda which points to a SATA drive.
2023-11-13Kernel: Add support for AHCI and make use of it with the current filesystem.Anton Kling
It will now also create a corresponding /dev/sd* device for each detected SATA drive. The filesystem still writes using the ATA driver. This should be fixed soon.
2023-11-13Memory: Fix problem where certain tables did not get marked as kernel.Anton Kling
This caused the tables to be cloned instead of having the pointer copied on the new page directory creations. This is just a solution to the symptom of having a bad design for memory managment. Maybe I will figure out something better.
2023-11-13Kernel: Remove kmalloc_eternalAnton Kling
I would like to be able to free some of those objects but I have not decided upon how that will be done yet. Even if not freeded the added complexity of having two functions does not make the extra bytes saved worth it IMO.
2023-11-13Crypto: 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.
2023-11-13Kernel: Add typedefs.hAnton Kling
2023-11-13ARP: Save the IP, MAC of incoming ARP requestsAnton Kling
2023-11-13Exceptions: Output CR2 on page faultAnton Kling
2023-11-12AHCI: Add very basic AHCI and some additional helper functions to mmu.cAnton 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.
2023-11-12Kernel/PCI: Add functions for getting BAR and specific PCI devices byAnton Kling
class
2023-11-10Ext2: Change char* to u8* where the type is referencing data and not a CAnton Kling
string
2023-11-10Kernel Style: Change uint*_t -> u*Anton Kling
2023-11-10Kernel/Memory: Fill new allocations with random data.Anton Kling
This should make it easier to spot uninitalized memory being used.
2023-11-10Syscall: Cleanup code and remove dumb usage of get_vfs_fd.Anton Kling
