procfs: Add `stat`

2024-12-14T17:14:19+00:00

procfs: Add `self` and `id`

2024-12-14T14:35:40+00:00

sb: Allow input to be "ignored"

2024-12-14T14:13:01+00:00

This removes edge cases from read calls and makes bugs harder to introduce.

formatting: Use clang-format on all projects

2024-12-12T15:03:08+00:00

This commit also add braces to all `if` statements.

signal: Remove old way of sending signals and instead use procfs

2024-12-12T14:48:20+00:00

procfs: Add a procfs

2024-12-12T14:48:19+00:00

Userland can now interface with processes by writing/reading from `/proc//` It can send signals, for example `echo 15 > /proc/1/signal`

kernel: Add a way to parse numbers from C strings

2024-12-09T22:27:48+00:00

After making this change I am now actually doubting if using C strings is a good idea and maybe it should just always just the string view library that userland makes use of. But old code and the upcoming commits rely upon this so it is a change my future less lazy self will do.

mmu: Make certain allocations physical and virtual mapping linear

2024-12-09T18:17:57+00:00

Previously it was possible for fragmentation to occur and as a result certain allocations would have a linear virtual address space but not a linear physical address space. This is bad since a lot of calls to kmalloc_align rely upon both being linear, it has now been changed such that all allocations done by kmalloc_align now guarantee this mapping holds for both virtual and physical addresses. It was due to oversight and sheer luck that this had been working for so long.

vfs: Bug fix...

2024-12-08T18:45:22+00:00

The commit is self explanatory. It was a simple mistype that went unnoticed for a while.

vfs: Force truncation even without permissions

2024-12-08T18:43:31+00:00

O_TRUNC as a mode does not seem to imply write permissions but we still wish to truncate the file before giving back a file descriptor. Therefore the kernel can now override any permission checks if it wishes to do a truncation while still using the "ordinary path".
