Andreas Kling 122d7d9533 Kernel: Add Credentials to hold a set of user and group IDs 
This patch adds a new object to hold a Process's user credentials:

- UID, EUID, SUID
- GID, EGID, SGID, extra GIDs

Credentials are immutable and child processes initially inherit the
Credentials object from their parent.

Whenever a process changes one or more of its user/group IDs, a new
Credentials object is constructed.

Any code that wants to inspect and act on a set of credentials can now
do so without worrying about data races.

About

SerenityOS is a love letter to '90s user interfaces with a custom Unix-like core. It flatters with sincerity by stealing beautiful ideas from various other systems.

Roughly speaking, the goal is a marriage between the aesthetic of late-1990s productivity software and the power-user accessibility of late-2000s *nix. This is a system by us, for us, based on the things we like.

You can watch videos of the system being developed on YouTube:

Features

  • Modern x86 32-bit and 64-bit kernel with pre-emptive multi-threading
  • Browser with JavaScript, WebAssembly, and more (check the spec compliance for JS, CSS, and WASM)
  • Security features (hardware protections, limited userland capabilities, W^X memory, pledge & unveil, (K)ASLR, OOM-resistance, web-content isolation, state-of-the-art TLS algorithms, ...)
  • System services (WindowServer, LoginServer, AudioServer, WebServer, RequestServer, CrashServer, ...) and modern IPC
  • Good POSIX compatibility (LibC, Shell, syscalls, signals, pseudoterminals, filesystem notifications, standard Unix utilities, ...)
  • POSIX-like virtual file systems (/proc, /dev, /sys, /tmp, ...) and ext2 file system
  • Network stack and applications with support for IPv4, TCP, UDP; DNS, HTTP, Gemini, IMAP, NTP
  • Profiling, debugging and other development tools (Kernel-supported profiling, detailed program analysis with software emulation in UserspaceEmulator, CrashReporter, interactive GUI playground, HexEditor, HackStudio IDE for C++ and more)
  • Libraries for everything from cryptography to OpenGL, audio, JavaScript, GUI, playing chess, ...
  • Support for many common and uncommon file formats (PNG, JPEG, GIF, MP3, WAV, FLAC, ZIP, TAR, PDF, QOI, Gemini, ...)
  • Unified style and design philosophy, flexible theming system, custom (bitmap and vector) fonts
  • Games (Solitaire, Minesweeper, 2048, chess, Conway's Game of Life, ...) and demos (CatDog, Starfield, Eyes, mandelbrot set, WidgetGallery, ...)
  • Every-day GUI programs and utilities (Spreadsheet with JavaScript, TextEditor, Terminal, PixelPaint, various multimedia viewers and players, Mail, Assistant, Calculator, ...)

... and all of the above are right in this repository, no extra dependencies, built from-scratch by us :^)

Additionally, there are over two hundred ports of popular open-source software, including games, compilers, Unix tools, multimedia apps and more.

How do I read the documentation?

Man pages are available online at man.serenityos.org. These pages are generated from the Markdown source files in Base/usr/share/man and updated automatically.

When running SerenityOS you can use man for the terminal interface, or help for the GUI.

Code-related documentation can be found in the documentation folder.

How do I build and run this?

See the SerenityOS build instructions. Serenity runs on Linux, macOS (aarch64 might be a challenge), Windows (with WSL2) and many other *Nixes with hardware or software virtualization.
