Bananymous 3666525d24 Kernel/LibC: Implement `readlink` in terms of `readlinkat` 2024-09-17 16:38:15 +03:00
Bananymous f1a4bbce53 Kernel/LibC: Implement all stat family functions with fstatat 
This patch gets rid of 2 unnecessary syscalls!
 2024-09-17 16:38:01 +03:00
Bananymous 708a720d9d Kernel: Remove SYS_OPEN 
This can be done with SYS_OPENAT with fd set to AT_FDCWD
 2024-09-17 16:16:47 +03:00
Bananymous 7177da7d62 LibC: Implement dummy get_rusage 
One port seems to use this function. This dummy just reports no used CPU
time for current process nor children

Bananymous 5e4aa75e03 Kernel: Perform access checks when creating a file or a directory 
Also SYS_CREATE_DIR now uses correct relative path. It used to always
create files relative to root. And as no permission checks were tested,
file creation succeeded to root as long as path did not contain '/' :D
 2024-09-17 15:57:07 +03:00
Bananymous d88ee5c9ee Kernel/LibC: Implement `creat` with `open` 
This allows getting rid of unnecessary SYS_CREATE. Directory creation
still has its own syscall, but I could combine it with SYS_OPEN also.

Bananymous d4ea720239 Kernel: Don't crash the kernel if ext2 encounters disk error 
This will most likely result in a corrupted filesystem, but crashing the
kernel is too much :D
 2024-09-17 15:54:33 +03:00
Bananymous 97ee370ffe Kernel: Allow listing files even if one of directories blocks are empty 2024-09-17 15:53:14 +03:00
Bananymous a084f83f4c Kernel: Rework kernel-side ELF loading 
ELFs are now loaded as MemoryRegions so they don't need special handling
anywhere. This also allows file backed COW optimizations to work. This
was not the case before.

This patch removes now obsolete LoadableELF and unused ELF files from
LibElf.

Bananymous 54732edff4 Kernel: Fix bugs in memory regions 
MemoryRegion::initialize() required size to be page aligned, this is not
necessary.

MemoryBackedRegion::copy_data_to_region() required user-write
permissions for underlying data. This did not matter as memory backed
regions dont support COW memory, but it could lead to bugs later on.

Bananymous 1a24d1839f LibInput: KeyEvent to ansi string now handles delete key 
This allows Terminal emulator to also handle delete key.

The value of `\0x7F` may be wrong as qemu's serial console seems to be
sending `\e[3~`

Bananymous c3040a04a3 Terminal: Optimize printing a lot 
Terminal used to run `yes` at around 400 lines per second

This patch pumps that to over 100'000 lines per second!

There are 2 optimizations done:
  1. only invalidate window once after rendering is done
  2. if printing more than `rows()` newlines skip prior data
