Red Bear OS 2b278390ee tun: wire TUN scheme into event loop + SLAAC RS/RA protocol
TUN integration:
- Smolnetd gains tun_scheme: TunScheme field and tun_file parameter
- on_tun_scheme_event() handler added (scheme event → poll)
- main.rs: EventSource::TunScheme, subscription, dispatch
- TUN devices can now receive and transmit packets through the netstack

SLAAC (RFC 4862):
- build_router_solicitation(): ICMPv6 Type 133 with source LL address option
- parse_router_advertisement(): ICMPv6 Type 134 with Prefix Information
  option extraction (on-link, autonomous, lifetimes)
- Slacd state machine: Idle → Solicited → Configured
  tick() drives RS retransmit (3 retries, 5s timeout)
  process_ra() extracts autonomous /64 prefixes
- ParsedRa, RaPrefix public structs for integration with IPv6 stack

Reference: Linux 7.1 ndisc_send_rs() / ndisc_router_discovery() /
addrconf_prefix_rcv()

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.
