Red Bear OS 5cfbe23b5c cleanup: fix unreachable pattern warnings in TCP/UDP socket options
TCP and UDP get_sock_opt/set_sock_opt had duplicate match arms
due to constant collisions (Linux-level values share namespace):

  TCP: TCP_MAXSEG=2, IP_TTL=2, SO_REUSEADDR=2 → kept TCP_MAXSEG
  UDP: IP_TTL=2, SO_REUSEADDR=2 → kept IP_TTL (more useful)

Removed unreachable arms with explanatory comments. The
collision is inherent — Linux uses different option levels
(SOL_SOCKET vs IPPROTO_TCP vs IPPROTO_IP) but Redox scheme
has a flat namespace. Applications that use multi-level
getsockopt() would need richer level dispatching.

Base

Repository containing various system daemons, that are considered fundamental for the OS.

You can see what each component does in the following list:

  • audiod : Daemon used to process the sound drivers audio
  • bootstrap : First code that the kernel executes, responsible for spawning the init daemon
  • daemon : Redox daemon library
  • drivers
  • init : Daemon used to start most system components and programs
  • initfs : Filesystem with the necessary system components to run RedoxFS
  • ipcd : Daemon used for inter-process communication
  • logd : Daemon used to log system components and daemons
  • netstack : Daemon used for networking
  • ptyd : Daemon used for pseudo-terminal
  • ramfs : RAM filesystem
  • randd : Daemon used for random number generation
  • zerod : Daemon used to discard all writes and fill read buffers with zero

How To Contribute

To learn how to contribute you need to read the following document:

If you want to contribute to drivers read its README

Development

To learn how to do development with these system components inside the Redox build system you need to read the Build System and Coding and Building pages.

How To Build

It is recommended to build this system component via the Redox build system, you can learn how to do it on the Building Redox page.

To build and test outside the build system, install redoxer then use check.sh script to build or test:

  • ./check.sh - Check build for x86_64
  • ./check.sh --arch=ARCH - Check build for specific ARCH (aarch64, i586, riscv64gc)
  • ./check.sh --all - Check build for all ARCH
  • ./check.sh --test - Check the base system boots up on x86_64

You can also use make install to inspect the content on ./sysroot, or make test-gui to test booting with orbital interactively.
