2024-03-26 | Kernel: Improve kmalloc security and performance | Anton Kling | |
Fill new and freed allocations with random data unless it is allocated from kcalloc in which case it should be zero filled. | |||
2024-03-26 | Increase support for signals | Anton Kling | |
2024-03-25 | Random changes | Anton Kling | |
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. | |||
2024-03-19 | IRC: Add the IRC client I am working on | Anton Kling | |
2024-03-17 | stuff | Anton Kling | |
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 | 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 | |
2023-11-29 | 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 | |||
2023-11-24 | 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. | |||
2023-11-22 | Networking: Split network packets if they are too large | 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 | 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 | |
2023-11-18 | VFS: Do not add extra '/' on root path. | Anton Kling | |
2023-11-17 | Kernel: Add isatty syscall | Anton Kling | |
2023-11-16 | VFS: Do canonicalization of the current working directory | Anton Kling | |
2023-11-16 | Kernel: Change how syscalls are built and implemented. | Anton Kling | |
2023-11-16 | ext2: Fix directory resolution | Anton 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. | |||
2023-11-15 | Add untracked files | Anton Kling | |
2023-11-15 | VFS/LibC: Add getcwd() | Anton Kling | |
2023-11-15 | Meta: Setup a drive over AHCI | Anton Kling | |
2023-11-15 | PCI: Add interrupt handler functions | Anton Kling | |
2023-11-15 | Kernel/LibC: Add chdir function and syscall | Anton Kling | |
2023-11-15 | VFS: Add stat | Anton Kling | |
2023-11-15 | VFS: Bug fix. Uninitalized structure member. | Anton Kling | |
This was found thanks to kmalloc now filling new allocations with random data. | |||
2023-11-15 | ext2: Bug fix. Add padding to the block group descriptor. | Anton Kling | |
2023-11-13 | AHCI: 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. |
