Bananymous 3750d29b2b Kernel: Fix possible out-of-bounds disk access in ext2 2023-09-08 02:42:53 +03:00
Bananymous e75522a005 BuildSystem: Cleanup disk image creation 2023-09-08 02:41:39 +03:00
Bananymous 5972c73950 LibC: fix fread implementation
fread() should read until either size*nitems bytes are read or eof
is reached.

Bananymous 41757b5f6c Shell: Clean exit on ^D and use getchar()
Use getchar() instead of fread(&ch, 1, sizeof(char), stdin). This
is much cleaner.

Bananymous c33c7f8b3b Init: use read instead of fread()
This allows actually correct behaviour. My fread implementation is
flawed. It should not return on '\n'

Bananymous 4648f6718e Kernel: Cleanup TTY::read() 2023-09-07 15:27:21 +03:00
Bananymous b30af0edca Kernel: TTY now reads input byte by byte
This allows correct behaviour for character streams / keyboard
handling. Serial input can now send working ^C :D

Bananymous 5e1725abb2 Kernel: Remove bitmap debug printing from ext2 inode allocation 2023-09-06 01:25:09 +03:00
Bananymous 6ad2f23259 Kernel: Correct inode links count 2023-09-05 14:46:56 +03:00
Bananymous 0d725f68e3 Snake render grid lines without extra space after last '#' 2023-09-05 14:35:53 +03:00
Bananymous 0770ba0936 BuildSystem: Don't set permissions on image creation
This is already handled by *new* tar ball sysroot

Bananymous c13b5aecfe Snake: Reorder apple generation/snake body update
If new apple was generated to heads previous position after update,
it would not render.

Bananymous 3892579049 Base: Add grub entries for serial-only boot
We can now fully boot with serial input and output :)

Bananymous 3fd94b1acb Kernel: You can now read serial output from the /dev/ttyS* 2023-09-05 01:07:52 +03:00
Bananymous 93c5755012 Kernel: Receive interrupts for COM1 and COM2 input
The input has to still be attached to terminal
2023-09-04 22:07:40 +03:00
Bananymous 323de3c866 Kernel: Rework whole Terminal structure
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

Bananymous 8032824054 BuildSystem: use -a with rsync
This allows cmake to not rebuild whole project every time
2023-08-28 11:38:17 +03:00
Bananymous 7aaea786c2 LibC: Don't undef needed values in inttypes.h 2023-08-24 15:48:14 +03:00
Bananymous ce8e8e68f4 BuildSystem: Add USES_TERMINAL when preparing sysroot
You were not able to enter sudo password on sysroot unpacking,
which caused ninja to hang
2023-08-23 20:48:40 +03:00
Bananymous 80e7a89f67 BuildSystem: Base sysroot is now distributed as a tar ball
This allows file and directory permissions work as intended.

cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Bananymous b5a7246ba7 LibC: make printf buffer only 128 bytes
Only reason for it to be big is if you want super large zero padding
for your number. This will eventually be handled without the buffer.
