Bananymous d7b8458a56 Kernel: Fix TCP sending 
TCP send was effectively always waiting for connection to close and then
return a value of 0.

Bananymous 61aa1ea11f sudo: Fix installation permissions 
I had accudentally removed SETUID bit from sudo. This required to
elevate the permissions.
 2024-06-24 15:00:08 +03:00
Bananymous 20aa7c79d1 BuildSystem: Fix crt file installation 
crt files should be installed always before userpace programs are
linked.
 2024-06-22 17:30:00 +03:00
Bananymous 22548a3f4a BuildSystem: Fix crt file installation 
crt files for userspace are now a dependency of libc, which means that
everytime libc gets installed, crt files will also install.

This fixes the problem when building libc
 2024-06-21 17:10:58 +03:00
Bananymous 9e1b5cbaab BuildSystem: Cleanup CMake code to allow libc only installation 
There was no way to just install libc which is required for stdlibc++
 2024-06-21 01:45:14 +03:00
Bananymous 1488ec5a03 Userspace: Implement the most basic http server 
This server just responds with static http "hello world" to every
incoming request
 2024-06-20 13:29:01 +03:00
Bananymous 4f0457a268 Kernel: Rewrite a lot of TCP code and implement TCP server sockets 
TCP stack is now implemented much closer to spec
 2024-06-20 13:26:50 +03:00
Bananymous 30fdc2198f BAN: Add exchage() to Atomic<T> 2024-06-20 13:24:42 +03:00
Bananymous bce16cdd6e Kernel: Fix how socket closing works 
Sockets are now closed only when they are not referenced any more. This
allows child process to close socket and still keep it open for the
parent.
 2024-06-19 10:39:44 +03:00
Bananymous d5daa46ab8 General: Add default .vscode directory 
The .vscode contains 2 C++ profiles that use my custom toolchain and
correct library include paths. One configuration is for kernel and other
for userspace
 2024-06-19 10:16:20 +03:00
Bananymous ad6d95ba52 BuildSystem: Rework the whole cmake build system 
Now files are installed using the install() command instead of manually
copying files to their destinations. This allows automatic recompilation
of headers that did not work previously
 2024-06-19 09:40:03 +03:00
Bananymous 318ce5dec8 All: Fix a lot of compiler warnings from header files 
While reworking build system, header files started to report warnings.
 2024-06-18 23:02:10 +03:00
Bananymous 526d4369ce Ports: Don't throw error if _installed_ does not exist 
This was annoying and I got multiple people reporting it as a possible
bug.
 2024-06-18 13:16:33 +03:00
Bananymous c69919738b BuildSystem: Move all userpace libraries under the userspace directory 
As the number of libraries is increasing, root directory starts to
expand. This adds better organization for libraries
 2024-06-18 13:14:35 +03:00
Bananymous 1b5a01a6c9 LibImage: Add support for PNG images 
I have not tested images with less than 8 bits per color or images with
indexed color as gimp could not export those. There is currently no
support for interlaced images.
 2024-06-18 02:37:46 +03:00
Bananymous f233715b70 BAN: Add d{print,want,error}ln_if macros for userspace 2024-06-18 02:35:45 +03:00
Bananymous a58ac18fa0 BAN: Add move constructors to ByteSpan 2024-06-18 01:52:02 +03:00
Bananymous f1e366d36f Kernel: Free keyboard mutex while waiting for data to read 
This was making select hang if one thread was trying to read from
keyboard.
 2024-06-17 23:04:37 +03:00
Bananymous 301dcd78cc LibImage: Compile with -O3 
This makes image resizing with cubic interpolation around 10x faster
 2024-06-17 23:03:52 +03:00
Bananymous 65c6d62a15 LibImage: Start work on PNG decoding 
This patch adds PNG decoder that currently only inflates the PNG's zlib
deflate stream
 2024-06-17 22:58:59 +03:00
Bananymous aaf7a249c6 image: Add nicer error message if image could not be parsed 2024-06-17 22:58:59 +03:00
Bananymous 0bc8d49684 LibImage: Add image format probing 
Instead of determining the image type in Image.cpp call image probing
functions for each supported image type
 2024-06-17 22:14:43 +03:00
Bananymous 17ecbca204 BAN: Add network_endian_to_host 2024-06-17 22:14:43 +03:00
Bananymous 78928b7eb4 Ports: Add curl port! 2024-06-17 21:40:13 +03:00
Bananymous 5236e1ef0d LibC: Add dummy functions for rename() and strftime() 
I don't really want to implement them right now, but they are required
to exist for some ports.
 2024-06-17 21:02:37 +03:00
Bananymous be7ed8e74a Kernel/LibC: Implement {get,set}sockopt() 
These are pretty much dummy functions in the kernel side. Only case that
is handled is SOL_SOCKET with SO_ERROR. This is hard coded to return no
error. Network stack is currently synchronous, so all errors are already
reported through synchronous network functions.
 2024-06-17 20:56:48 +03:00
Bananymous 78bcb85679 LibC: Implement gethostbyname() 
This is not a POSIX function, but curl seems to depend on it. It is
even deprecated on linux...
 2024-06-17 20:55:50 +03:00
Bananymous b98bb9eb27 LibC: Add HOST_NAME_MAX definition 2024-06-17 20:55:17 +03:00

Bananymous dafd2fecf7 LibC: Implement gmtime() and localtime() 
localtime() just returns gmtime() as there is no timezone support
 2024-06-17 16:51:41 +03:00
Bananymous 9c5cca784e LibC: Implement bsearch() 2024-06-17 16:51:24 +03:00

Bananymous dd64e2060e WindowServer: Add support for background images 
WindowServer now looks in _$HOME/.config/WindowServer.conf_ for a
configuration file that can specify a background image.

Also add default background image /usr/share/images/sample.ppm to the
base sysroot provided in the git repo.
 2024-06-16 00:28:09 +03:00
Bananymous 14d4551476 LibImage: Add rgba getter for Image::Color 
Actually the format is 0xAARRGGBB which is what my framebuffer uses.
 2024-06-16 00:23:02 +03:00
Bananymous e6549b0fe8 LibImage: Implement (bi)cubic interpolation 
This is kind of slow but yields much nicer results compared to
(bi)linear interpolation. I should probably add gamma correction...
 2024-06-15 23:05:10 +03:00
Bananymous 157e05f57c image: Implement --scale argument to scale image to framebuffer 
Also fix bug where red and blue channels were flipped
 2024-06-15 17:24:01 +03:00
Bananymous 96efd1e8b9 LibImage: Implement image resize using nearest or bilinear filters 2024-06-15 17:23:24 +03:00
Bananymous 672ce40618 LibImage: Move userspace image parsing to its own library 
The image utility now uses this tool instead of parsing images on its
own.
 2024-06-14 11:05:54 +03:00
Bananymous 05e9d76c77 BAN: Implement will_{addition,multiplication}_overflow 2024-06-14 11:04:29 +03:00
Bananymous ea7fc7f6c4 Kernel: Implement read-only FAT12/16/32 driver with long name support 
You can now mount FAT filesystems! This code might not work perfectly
but my quick testing seemed to work on all (FAT12/16/32) variants.
 2024-06-14 01:04:12 +03:00
Bananymous 6b1d5d28be Kernel: VFS root now has to be block device instead of partition 2024-06-14 00:19:12 +03:00
Bananymous a9b0bfa740 LibC: Make ino_t always 64 bit 2024-06-14 00:18:21 +03:00
Bananymous cc6b80a55b BAN: Optimize Vector copy assignment to reduce allocations 
If vector contains enough elements, it will now replace old elements
instead of clearing and reallocating
 2024-06-14 00:17:28 +03:00
Bananymous 6707989cd5 BAN: Implement same_as and add requires for BAN::Function with lambda 
BAN::Function(lambda) now requires that the object is callable and
returns the correct type. This allows overloads with different
callback formats.
 2024-06-14 00:15:48 +03:00
Bananymous 766439db6d Kernel: Start work on adding support for new filesystems 
Old code tried to create ext2 filesystem from all devices.

Bananymous 7bb1a3906d BuildSystem: Run kvm-ok to determine kvm access 2024-06-10 16:10:05 +03:00
Bananymous 530c259e71 Kernel: Close unix domain socket when it gets destoyed 
Inode closing is something that needs a complete rework. Currently all
sockets are closed when close() is called, which leads to connection
closing if you fork()/exec() with socket being marked as CLOEXEC.

Inodes should probably only be closed once they are not referenced
anywhere.
 2024-06-03 18:06:01 +03:00
Bananymous 843a6851c4 Userspace: Start work on a terminal emulator 
Terminal is still missing some ANSI codes, cursor and pseudo terminal
support.

Shell's builtin start-gui now launches a Terminal instead of test
windows.

Bananymous cfdce9be61 BAN: Mark RefPtr and WeakPtr helper destructors virtual 
Also fix a bug in WeakPtr::lock() which would assert false if the
underlying weak link was not initialized
 2024-06-02 16:50:26 +03:00
Bananymous 446220494e Kernel: Unix domain sockets close can now be detected 
When a unix domain socket is closed and it has a connection to another
socket, it will make the other socket readable and recv will return 0.

This allows detection of socket closing
 2024-06-02 16:48:55 +03:00
Bananymous f12ffa92a0 LibFont: Font::get_glyph() now returns nullptr if glyph does not exist 
This allows getting glyphs with a single hash lookup

Bananymous 84b3289a2a Kernel: Move Scheduler::yield() lock check after interrupts disabled 
I have no idea why this solves a bug where current processor has
scheduler lock at the beginning of yield.
 2024-05-31 02:56:39 +03:00
Bananymous b760892de2 Kernel: Make pselect use nanosecods instead of milliseconds 2024-05-31 02:56:17 +03:00

Bananymous 076f1efecb Kernel: Fix 32 bit fast page locking 
I forgot to change this when changing the lock type. 32 bit boots again
fine :D
 2024-05-29 19:44:39 +03:00
Bananymous b23511edb1 LibC: Don't use BAN inside pwd.cpp 
This made pwd.cpp require libstdc++ which meant that getlogin() also
needed libstdc++. This made build process of libstdc++ require itself
which is of course not possible.
 2024-05-29 19:12:15 +03:00
Bananymous 53e572f072 Kernel: Fix s_fast_page_lock type on 32 bit target 2024-05-29 18:04:23 +03:00
Bananymous c2b6ba0d5a Userspace: Start work on GUI and WindowServer 
Current implementation can create custom windows and each window has
its own framebuffer. When window wants to write its framebuffer to the
screen it will send a message to the WindowServer using unix sockets.
 2024-05-29 16:00:54 +03:00
Bananymous d4d530e6c8 Kernel: Implement basic shared memory objects 
These can allocate memory that can be shared between processes using
a global key. There is currenly no safety checks meaning anyone can
map any shared memory object just by trying to map every possible key.
 2024-05-29 15:58:46 +03:00
Bananymous 99270e96a9 Kernel: Lock debug lock while printing fault details

Bananymous 87d52e5ebe Kernel: Fix timer early wake message 
When printing early return message, current time was read twice. This
could lead to early return check failing, but when printing and reading
the time again subtraction overflow would happen.
 2024-05-28 16:04:18 +03:00

Bananymous f5987b68ff BAN: Mark some class methods as constexpr 2024-05-28 01:07:29 +03:00
Bananymous a1ab44d39f Kernel: Optimize disk reads to read multiple sectors at once 
Old StorageDevice::read_sectors() read each sector separately if the
underlying disk had a disk cache. This patch allows multiple sectors to
be read even if the disk cache exists and contains some of the sectors.

Only sectors that could not be found from the disk cache are actually
read from the disk. This optimization is not done for writing, which
still will write each sector separately, if disk cache has no memory to
store new sectors. It would feel kind of unnecessary optimization as you
have greater problems if disk cache cannot allocate a single page.
