Bananymous 8f8d6bddc0 Kernel: Unify PS2Device to handle commands instead of inherited 2024-01-04 12:04:45 +02:00
Bananymous d2d12d5281 Kernel: validate_{string,pointer}_access now return ErrorOr<void> 
Now that signals are only processed when returning to userspace,
address validation has to do an early return.

Bananymous 0ba278041b Kernel: Start exec by loading the ELF file. It might not exist... 2024-01-03 23:50:02 +02:00
Bananymous ccaa159a73 Bootloader: Add support for ext2 blocks up to 4 KiB 
This should work with blocks bigger than that, but my linux system
only supports up to 4 KiB, so I cannot test this.

This allows getting rid of forced block size in mkfs and let the
program select appropriately sized blocks.

Bananymous 7356a83a44 Bootloader: Optimize some unnecessary branches on carry add/sub 2024-01-03 17:05:33 +02:00
Bananymous 2a68df81e2 Bootloader: Fix bootloader on bochs 
Bochs int 0x10 seems to scrap full ebp and top bits in some
registers. I now save all 32-bit registers on call frame. Also
ebp is across all int 0x10 calls.

Bananymous 50ca2ac09e Bootloader: Interpret 0x7F (DEL) as backspace 
This allows backspace to work over qemu's serial connection

Bananymous b0ff2392a1 Kernel: Add some helpful debug prints 
Log RIP when stack pointer is out of bounds.

Log all syscalls that return ENOTSUP

Bananymous 001e95f973 Kernel: Optimize sse saving/loading 
Only save and load sse when new thread is trying to execute sse
instruction. There is no need to do that every time we enter kernel.

Bananymous 1bd33e76e5 cat/cat-mmap: print newline if file doesn't end in one 2024-01-02 23:27:13 +02:00
Bananymous 9fa13079f2 Kernel: Implement supplementary groups 
This code has very ugly file parsing code. I have to create API
for reading files line by line in kernel space...

This allows users to open framebuffer/input files without root.

Mounting has to be moved to userspace soon. It makes no sense to
hard code permissions for every (device) file.

It used to be Vector<Vector<T>> but this feels more proper

Bananymous 79a15132da BAN: Cleanup HashSet 
I now use BAN::Iterator as the base iterator. Also unstable version
was added.

Bananymous bacc0db778 BAN: Fix unstable hash map rebucket 2023-12-23 16:31:42 +02:00
Bananymous 3963afe343 BAN: Add unstable version of hash map 
This version differs only when doing rebucket. If rebucket fails,
the whole hash map is invalidated. This allows rebucketing to use
moving instead of copying.
