The previous tokio = { features = ["full"] } pulled in tokio::signal
(including tokio::signal::unix::SignalKind::terminate). On Redox the
libc signal-handler registration path is incomplete; calling
enable_all() in main triggered a protection fault inside relibc, and
the kernel then panicked on unreachable code in
process::exit_this_context (see kernel/src/syscall/process.rs:79).
Two-part fix:
- Cargo.toml: scope tokio features to rt, rt-multi-thread, macros,
net, time, sync. This drops and , which are
unavailable on Redox anyway. The init system manages the daemon
lifecycle, so a signal handler is not needed in this daemon.
- src/main.rs: spawn_signal_handler becomes a no-op. The shutdown_tx
channel is preserved for any future internal shutdown signaling.
The SIGTERM path is removed entirely.
This unblocks Phase 2.1 by removing the kernel panic cascade: the
protection fault no longer fires, the kernel's exit_this_context
reaches the context switch cleanly, and the previous
unreachable!() panic no longer triggers.
Both daemons previously checked /scheme/acpi/thermal (thermald) and
/scheme/acpi/power (redbear-upower) existence with Path::exists or
is_dir, which use stat/lstat. On Redox these syscalls can return
errors for scheme paths even when the scheme IS registered, leading
to false 'unavailable' warnings even after the new acpid thermal/
power directories were added.
Use fs::read_dir (which already worked for actual zone enumeration)
as the existence probe instead. The match expression intentionally
calls read_dir to discard the iterator and keep only the Result;
using ? here would break the warn-once pattern.
- Add x11proto to redbear-full.toml package list
- libxau recipe updated with x11proto dependency and custom build script
- Fixes libxau build failure: 'Package xproto was not found'
Add redbear-usb-storage-check in-guest binary that validates USB mass
storage read and write I/O: discovers /scheme/disk/ devices, writes a
test pattern to sector 2048, reads it back, verifies match, restores
original content. Updates test-usb-storage-qemu.sh with write-proof
verification step.
Includes all accumulated Red Bear OS work: kernel patches, relibc
patches, driver infrastructure, DRM/GPU, KDE recipes, firmware,
validation tooling, build system hardening, and documentation.
