- tcp/scheme/tcp.rs: write_buf now returns the actual bytes from send_slice() instead of buf.len(). Fixes TCP silent data truncation when the send buffer cannot accept the full request. - netstack/scheme/ip.rs: fpath() uses .expect() with a message in place of .unwrap() for clearer diagnostics on buffer write failure. - dhcpd/main.rs: parse the first non-flag positional argument as the interface name. Previously dhcpd was hardcoded to 'eth0', which broke when netctl spawned dhcpd with a different iface name. - drivers/common/dma.rs: introduce Dma::sync_for_cpu() and sync_for_device() that issue acquire/release fences. Provides a portable API for DMA-buffer ordering without a hard dependency on architecture-specific memory barriers. - drivers/net/virtio-netd/scheme.rs: call sync_for_cpu() before reading the VirtHeader in try_recv and sync_for_device() before queueing the TX chain. Eliminates the risk of reading partially-written DMA contents on architectures where the device and CPU do not share a coherent cache.
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.
