Bananymous d395cf38b7 Kernel: Binding to port 0 will always find unused port 2024-09-22 17:30:01 +03:00
Bananymous 57aec2a733 Kernel: Validate pointer's when printing stack trace 
There was an kernel panic if stack trace contained uncanonical
addresses.
 2024-09-22 17:16:01 +03:00
Bananymous ae89237453 Kernel: Disable warning when calling syscall 
This warning is only generated when compiling with UBSAN and I don't see
how the value would even be uninitialzed.
 2024-09-22 17:15:07 +03:00
Bananymous 60d5257678 Kenrel: Add __builtin_unreachable support for UBSAN 2024-09-22 17:14:36 +03:00
Bananymous d59463d11b Kernel: Fix TTY reading one keyevent after disabling input handling 2024-09-22 17:13:10 +03:00
Bananymous 1280528e4e BuildSystem: Use -O2 for all libraries 
I don't know why I had not specified optimization level for libraries.
Only LibImage was using explicit -O3. LibImage doesn't need O3 anymore
as O2 seems to be around the same speed.
 2024-09-20 20:04:49 +03:00
Bananymous 23d6205659 Kernel: Move DEBUG_* macros to centralized Debug.h 
This makes toggling debug info much easier
 2024-09-20 11:00:07 +03:00
Bananymous bc0acc6f44 Kernel: Validate network packet sizes before casting 
This caused a lot of crashes on invalid packets :D
 2024-09-20 10:46:59 +03:00
Bananymous b8622f2b4b Kernel: Implement simple RTL8169 driver 
This allows me to use internet when running banan-os on my hardware!
 2024-09-19 22:58:03 +03:00
Bananymous 7f0c39fe91 Kernel: Don't crash the kernel if packet is smaller than ethernet hdr 2024-09-19 22:51:55 +03:00
Bananymous a489be0e05 Kernel: Allow parallel LAPIC timer initialization with HPET 
HPET supports reading LAPIC counter without locks, so it can be done in
parallel. This makes booting much faster. Previously initializing every
timer took 100 ms, so 16 CPUs took total of 1.6 seconds. This allows
doing it all in 100 ms.
 2024-09-19 14:41:59 +03:00
Bananymous 8e08046519 Kernel: Add asserts about having locked TTY's write lock 
This for some reason fixes booting on real hardware? :D
 2024-09-18 00:56:48 +03:00
Bananymous 999eb53364 Kernel: Release debug lock if its locked during kernel panic 
Also kernel panic now prints if it had lock
 2024-09-18 00:56:02 +03:00
Bananymous f7e549e412 Toolchain: Run strip after installing toolchain 
This drops installed toolchain size to around fifth :D
 2024-09-17 22:30:40 +03:00
Bananymous fbb99de728 ls: Show symlink target with -l 2024-09-17 19:12:34 +03:00
Bananymous 0620ed3d4f Kernel: Fix file open permissions for some syscalls 2024-09-17 19:11:48 +03:00
Bananymous b779b3cf2d Kernel: Move file finding code to a helper 2024-09-17 18:52:52 +03:00
Bananymous a6b973003b WindowServer: chmod the correct file 2024-09-17 18:35:27 +03:00
Bananymous e431e90b20 Kernel/LibC: Implement all chown family function with fchownat 2024-09-17 18:35:01 +03:00
Bananymous 4aa466b948 Kernel/LibC: Implement all chmod family functions using fchmodat 2024-09-17 17:19:26 +03:00
Bananymous 04ae53b6df Shell: Add back accidentally deleted cd and time builtins 2024-09-17 16:38:45 +03:00
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
 2024-09-17 15:59:22 +03:00
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.
 2024-09-17 15:55:53 +03:00
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.
 2024-09-15 23:57:34 +03:00
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.
 2024-09-15 23:18:05 +03:00
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~`
 2024-09-15 03:13:21 +03:00
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
 2024-09-15 03:12:26 +03:00

Bananymous 04c715d314 BuildSystem: Build all libraries in root build directory 
I could not figure out how to use cmake's rpath to build libraries with
DT_NEEDED only containing the library name, not a relative path.
 2024-09-02 21:31:08 +03:00
Bananymous 35743cc8e6 LibC: Compile both static and shared version of LibC
