Bananymous c69efc040c Kernel: Scheduler now uses the new LinkedList API for moving threads 
Scheduler doesn't have to depend on the fact that allocations should
work when same amount of memory is just deallocated

Bananymous ca8e7b40bc Kernel: Implement SpinLock without CriticalScope 
This actually is not even spinlock since it yields the current
thread. It will become one when I get to SMP though...

Bananymous db933d5466 Kernel: Improve keymap file loading 
Now you can include other files in keymaps and set which keys are
modifier keys

Only keys that are set in keymap file are actually updated
 2024-01-12 02:55:06 +02:00
Bananymous 83ca469ed7 Kernel: Modifier keys are taken from current keyboard layout 
I used to assume where all modifiers were, but they are now taken
from keyboard layout.
 2024-01-11 11:53:11 +02:00
Bananymous d2c0718f7d Kernel: Fix toggleable modifier keys and add two more keys 2024-01-11 11:43:05 +02:00
Bananymous ab39c6541a Kernel: Require keymap loading superuser privileges 2024-01-10 14:50:30 +02:00

Bananymous 961ab9768a Kernel: KeyEvent is now well known keycode 
Keycodes are easier to handle as you need only one keyboard layout
for keycodes. Otherwise you would need to implement keyboard layout
for every keyboard driver in every language.
 2024-01-10 12:51:24 +02:00
Bananymous e4f48cbc73 Kernel: Move PS/2 command queue to controller instead of device 2024-01-09 20:00:19 +02:00
Bananymous e8f853a197 Kernel: After device updates, reschedule instead of sleeping 2024-01-09 11:21:00 +02:00
Bananymous d760239748 Kernel: Do a big rewrite of PS/2 code 
Command sending+response reading is now synchronized. This allows
bochs to properly initialize both mouse and keyboard simultaneously.

Also status register is checked EVERY time read/write to other IO
ports is performed.
 2024-01-08 10:50:55 +02:00
Bananymous f0cf54e194 Kernel: Reads from PS/2 keyboard and mouse can be terminated 2024-01-05 12:13:44 +02:00

 2024-01-04 12:17:55 +02:00
Bananymous e45b544a39 Kernel: Implement PS/2 mouse driver 
This is realtively simple driver that queries extensions (scroll +
extra buttons) from mouse and reads mouse packages.
 2024-01-04 12:17:55 +02:00
Bananymous d1e187570e Kernel: Fix old keyboard command 2024-01-04 12:08:23 +02:00
Bananymous d4191c0d94 Kernel: Reorganize PS/2 files to their own directory 2024-01-04 12:04:45 +02:00

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.
 2024-01-03 23:53:04 +02:00
Bananymous 0ba278041b Kernel: Start exec by loading the ELF file. It might not exist... 2024-01-03 23:50:02 +02:00
Bananymous b0ff2392a1 Kernel: Add some helpful debug prints 
Log RIP when stack pointer is out of bounds.

Log all syscalls that return ENOTSUP
 2024-01-03 02:08:01 +02:00
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.
 2024-01-03 02:06:49 +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.
 2024-01-02 23:24:32 +02:00
Bananymous 96d831c31a Kernel/LibC/Userspace: Implement chown and set tty owner on login 2024-01-02 22:19:38 +02:00
Bananymous 4307968182 All: Start work again on sse support 2023-12-28 19:14:42 +02:00

Bananymous 2e858fddb5 Kernel: Remove obsolete Scheduler::is_valid_tid() 
This function was used when processes could die at any point in time.
Now that processes can only die in known spots, we can be sure they
are not holding any locks. This allows much more performant locking.
 2023-12-07 13:26:42 +02:00
Bananymous 12474addda Kernel: Make Inodes use the new lock 
Also remove old lock from TTY since it can just use the one Inode
already has.
 2023-12-07 13:19:12 +02:00
Bananymous 7c25e4ce5a Kernel: Implement RecursivePrioritySpinLock 
This locks won't allow locking from userspace thread if there is
kernel thread waiting to lock this.
 2023-12-07 13:18:21 +02:00
Bananymous 24b71d1170 Kernel: Appreciate setuid and setgid bits executables 2023-12-06 18:14:27 +02:00

Bananymous 1c78671078 Kernel: Rework all signal code 
Signal handling code was way too complex. Now everything is
simplified and there is no need for ThreadBlockers.

Only complication that this patch includes is that blocking syscalls
have to manually be made interruptable by signal. There might be some
clever solution to combat this is make this happen automatically.
 2023-12-06 13:02:17 +02:00
Bananymous cdcc36efde Kernel: Remove unnecessary raise syscall 2023-12-06 13:00:45 +02:00

 2023-12-01 01:22:53 +02:00
Bananymous c1cac43f28 BuildSystem: Don't build lai with -Wstack-usage 
Lai has two functions that trigger warnings on gcc. There isn't
really anything I can do about it, so just disable the warning
 2023-12-01 01:22:53 +02:00
Bananymous fdb6dc94ba Kernel: cast between inheritance with static_cast 
using reinterpret_cast is not a good idea. preferably we would use
dynamic_cast, but that is not possible since kernel is compiled with
-fno-rtti.
 2023-11-29 20:50:57 +02:00
Bananymous 327b330338 Kernel: Make internal framebuffer bpp constexpr defined in libc 2023-11-29 20:07:33 +02:00

Bananymous ab9954fe73 Kernel: Delete the now obsolete VesaTerminalDriver 2023-11-22 21:59:11 +02:00
Bananymous fd18071975 Kernel: Implement TerminalDriver for Framebuffer device 
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.
 2023-11-22 21:57:17 +02:00

Bananymous 7a8fd6d04a Kernel: TmpFS doesn't mark any functions as final 
I didn't think these would be overloaded, but they are
 2023-11-21 15:19:34 +02:00
Bananymous b749963b62 Kernel: Add common {read,write}_blocks() api to BlockDevice 2023-11-21 15:19:07 +02:00
Bananymous 6a068fb9f9 Kernel: Move Partition to its own file 2023-11-21 15:16:04 +02:00
Bananymous cadb56d8ba Kernel: ProcFS inodes reflect processes ruid/rgid 
setgid/setuid did not change the permissions of procfs inodes. This
made Shell launched by init not appear in meminfo.
 2023-11-18 14:26:44 +02:00
Bananymous c9e9cfd361 Bootloader: Implement VESA video mode query and pass it to kernel 
Kernel now gets framebuffer from bootloader. Framebuffer dimensions
and bpp are hardcoded in bootloader, but will probably be read from
config file at some point.
 2023-11-17 22:45:35 +02:00
Bananymous cb5a5d3ed1 Kernel/Bootloader: banan-os can now be booted with my bootloader :D 2023-11-17 20:33:02 +02:00
Bananymous 95af728e39 Kernel: Don't calculate divisor in a for loop in ext2 inodes 2023-11-17 19:02:01 +02:00
Bananymous 24d87acec4 Kernel: Serial now uses random size for some serial ports 
If the serial port doesn't repond with a size, just use a random
one. There is no reason to ditch the whole output if you cannot
determine its size.
 2023-11-17 18:56:02 +02:00
Bananymous 84040e64b8 Kernel: Don't use multiboot2 explicitly. Parse it to common structure 
This allows support of multiple different bootloaders
 2023-11-17 18:54:59 +02:00

Bananymous d6ae1bcf36 Kernel: Remove now obsolete RamFS 
Everything is using now the better TmpFS which uses physical pages
for page allocation instead of the static kmalloc memory.
 2023-11-07 16:07:11 +02:00
Bananymous 5044810451 Kernel: Make DevFS use the new and better TmpFS instead of RamFS 2023-11-07 16:05:05 +02:00

Bananymous ba2f09a4e6 Kernel: Cleanup TmpFS code and block access doesn't require allocs 
TmpFS blocks are now accessed with a simple wrapper
 2023-11-06 20:07:09 +02:00
Bananymous c92c1b8e2b Kernel: TmpInode blocks are on demand allocated 2023-11-06 10:44:37 +02:00

Bananymous 99d7b0917d Kernel: Start work on proper TmpFS in Heap instead of kmalloc memory 2023-11-04 18:18:45 +02:00
Bananymous 8b4e129fc1 Kernel: Add better APIs for fast page 2023-11-04 18:13:16 +02:00
Bananymous f6c312a6b3 BuildSystem: using sysroot doesn't need root privileges anymore! 
Sysroot is now created with fakeroot. This allows root access to be
only needed for disk image creation, since it uses loopback devices.
 2023-11-04 17:50:43 +02:00
Bananymous ca34ece8ef BAN: Update ASSERT api 
its now much harder to mix < with <= and > with >=
 2023-11-02 00:01:12 +02:00
Bananymous 71ecdd7245 Kernel: Canonicalize vaddr before using it 2023-10-30 19:20:17 +02:00
Bananymous b80b59ce24 Kernel: Remove unused externs in kernel.cpp 2023-10-30 19:09:31 +02:00
Bananymous 640d27748f Kernel: Temporarily force FileBackedRegion mappings writable 
Now that write-protect bit is enabled this is neccessary.
 2023-10-30 19:08:33 +02:00
Bananymous 42772611ce Kernel: Add fast page to page table 
Add "fast page" to KERNEL_OFFSET. This is always present in page
tables and only requires changing the page table entry to map. This
requires no interrupts since it should only be for very operations
like memcpy.

I used to map all temporary mappings to vaddr 0, but this is much
better. C++ standard always says that nullptr access is undefined
and this gets rid of it.

Fixed some bugs I found along the way
 2023-10-30 19:02:09 +02:00
Bananymous 6e676ee8c5 Kernel: Remove GeneralAllocator since it was not used 2023-10-30 18:13:17 +02:00

Bananymous 6ef153b6ca Kernel: Enable Write Protect. This seems to be good for security 2023-10-30 12:23:22 +02:00
Bananymous 130a69bac6 Kernel: Fix stack OOB detection 
I now check both interrupt and normal stack to detect OOB. Processes
are killed if they encouner stack over/under flow.
 2023-10-30 12:17:08 +02:00
Bananymous 0b5fcb3f88 Kernel/LibC: Add crt* files to LibC and remove crt0 from kernel 
There was no reason for libc get crt0 from kernel.
 2023-10-30 11:06:13 +02:00
Bananymous 18f61c5427 Kernel: Fix ACPI DSDT address 
Read x_dsdt address only if fadt's length contains it. Bochs seems
to have version 1 fadt without the x_* fields.
 2023-10-29 21:35:11 +02:00
Bananymous 76f48f095c Kernel: Rewrite a lot of ext2 code 
This commit consists of multiple big changes

1. blocks for inodes are now allocated on demand
  - reading from non allocated block will just return zeroes
  - writing to non allocated block allocates it

2. code doesn't really use raw pointers anymore
  - all casts to uint32_t or structures are now replaced with
    spans. either as<T> or as_span<T> which both are bounds
	checked

3. code doesn't depend on random macros for accessing indirect blocks
  - i added some recursive functions which take care of this :)

Bananymous 240a687d8f Kernel: Fix ext2 inode block allocation with triply indirect blocks 2023-10-28 16:53:00 +03:00
Bananymous 35b46e37bb Kernel: Fix ext2 inode deletion cleanup 
I now cleanup all blocks (including direct) in i_block array

Bananymous 87ff38664a Kernel/LibC: Add syscall and wrapper for unlink 2023-10-25 21:45:04 +03:00
Bananymous b7007016c0 BAN: Implement Ext2 file unlinking 
Ext2 inodes can now be unlinked from directories and after last
inode closes (destructor gets called) we check if link count is 0
and cleanup the inode from filesystem
 2023-10-25 21:43:36 +03:00
Bananymous 6ee4d10651 Kernel/LibC/Userspace: Implement mkdir and creat 
Touch now uses creat insteadd of open with O_CREAT flag
 2023-10-25 21:07:26 +03:00
Bananymous e9b7cf332d Kernel: Implement directory creation for RamFS 2023-10-25 19:41:34 +03:00
Bananymous 4ee2f0f789 Kernel: Implement Ext2 directory creation 2023-10-25 19:37:04 +03:00
Bananymous 18e90d305d Kernel: Add Inode API for creating directories 2023-10-25 19:36:04 +03:00
Bananymous fd1b331b86 Kernel: Ext2FS now uses Ext2Inodes as cached values 2023-10-25 19:34:00 +03:00
Bananymous 5c51d09309 Kernel: Fix read offset of RamFileInode 2023-10-25 02:53:20 +03:00

 2023-10-24 11:56:25 +03:00
Bananymous f3d9da9549 Kernel: Rewrite all read/write functions to use BAN::ByteSpan 
This allows us to not work with raw pointers and use sized containers
for reading and writing.
 2023-10-24 11:56:00 +03:00
Bananymous c17cdb39d5 Kernel: Map multiboot2 memory in PageTable initialization 
It cannot be assumed that multiboot data lies between kernel_end
and 2 GiB mark, so I properly allocate virtual address space for it.
 2023-10-17 01:15:08 +03:00
Bananymous 69a39b7077 Kernel: Start using multiboot2 instead of multiboot 
This allows better compatibility with (U)EFI and gives RSDP location
instead of me having to scan ram to find it.
 2023-10-17 01:06:24 +03:00
Bananymous 19696bdad3 Kernel: TTY doesn't panic if it doesn't find input device 2023-10-16 16:58:39 +03:00
Bananymous 00dd7d85ce Kernel: Fix device identification with all bits as ones 
If device identification sends all ones, don't initialize the device.
 2023-10-16 16:57:07 +03:00
Bananymous 0c88c74b76 Kernel: ATABuses are but to compatibility mode if possible 
I don't support native mode ata bus (irq sharing) so ata buses are
but to compatibility mode if possible.
 2023-10-16 16:56:12 +03:00
Bananymous c4a640bcb6 Kernel: Fix ATADevice naming 
ATADevice now stores its name instead of using static buffer. Old
static buffer was changing on every name query. I just hadn't noticed
since virtual machine disks were always sda.
 2023-10-16 16:52:15 +03:00
Bananymous 0fdf8b6f68 Kernel: Fix PCI bugs 
IO BarRegion used vaddr instead of the correct paddr. Add API for
memory region iobase query.
 2023-10-16 16:50:49 +03:00
Bananymous 37bc52988c Kernel: Don't require framebuffer 
Initializes virtual tty only if framebuffer is initialized
