This commit replaces the D-Bus implementation stubs and gaps identified
during the zbus/D-Bus review round with real, tested implementations.
**redbear-sessiond: real login1 properties + PrepareForShutdown signals**
The login1.Manager interface had hardcoded stub values:
- idle_since_hint() and idle_since_hint_monotonic() returned 0
- inhibit_delay_max_usec() returned 0
- handle_lid_switch() returned 'ignore'
- handle_power_key() returned 'poweroff'
- power_off/reboot/suspend wrote to /scheme/sys/kstop but did NOT
emit PrepareForShutdown(before=true) / PrepareForSleep(true) first
Replace with:
- Run-time configurable atomic fields (last_activity_us,
inhibit_delay_max_us) and RwLock<String> fields (handle_lid_switch,
handle_power_key) on SessionRuntime, mutated by the existing control
socket. Defaults: 5s inhibit delay, 'ignore' lid, 'poweroff' power key.
- power_off/reboot are now async, emit PrepareForShutdown(true) before
/scheme/sys/kstop write, emit PrepareForShutdown(false) after a
successful write, and return a D-Bus error if the kstop write fails
(resetting preparing_for_shutdown).
- suspend emits PrepareForSleep(true)/(false) similarly.
- Bash-style dangling-Clone problem solved via manual Clone impl on
SessionRuntime that snapshots the atomics and lock contents.
**redbear-wifictl: real NetworkManager-shaped D-Bus interface**
The dbus-nm feature was a no-op stub that just logged 'registered'
without actually doing anything. Replace with a real zbus interface:
- zbus::interface structs wrapping Arc<Mutex<NmWifiDevice>> shared state
- org.freedesktop.NetworkManager at /org/freedesktop/NetworkManager
exposes WirelessEnabled, WirelessHardwareEnabled, State, and
GetDevices().
- org.freedesktop.NetworkManager.Device.Wireless at
/org/freedesktop/NetworkManager/Devices/0 exposes HwAddress,
PermHwAddress, State, Ssid, Strength, LastScan, AccessPoints,
GetAccessPoints(), WirelessCapabilities.
- register_nm_interface() now actually builds a blocking
zbus::connection::Builder on the session bus, registers both
service name + object paths, spawns a background thread to hold the
connection alive, and returns. On session-bus connect failure it
logs an error and returns without crashing.
- When the dbus-nm feature is disabled, behavior is unchanged (no-op).
- Type model enriched: NmWifiDevice gains last_scan, active_ssid,
active_strength fields + Default derives; NmDeviceState gains
Default; NmAccessPoint gains Default.
**redbear-statusnotifierwatcher: wired into redbear-full**
The recipe compiled and had 12 tests but was NOT in any config —
the binary never deployed. Add:
- [package.files] stanza to its recipe.toml so the binary is staged
- redbear-statusnotifierwatcher = {} to config/redbear-full.toml
- launch_optional_component invocation in redbear-kde-session
**redbear-notifications: 8 host unit tests**
Previously zero tests. Add a #[cfg(test)] module covering:
- monotonic notification IDs
- capabilities list (spec values present)
- server information strings
- close-id + reason recording
- action invocation payload
- ordering preserved across multiple notifications
- independence between close and action records
**zbus build-ordering marker: clean source**
The marker source lib.rs contained 'pub struct Connection;' which
is misleading. Replace with a minimal comment explaining the
build-ordering purpose. The actual zbus crate is still resolved by
Cargo at downstream build time (unchanged behavior).
**D-Bus symlink cleanup**
Remove recipes/system/dbus/dbus-root-uid.patch (orphan symlink, not
in .gitignore-relevant scope). The actual patch stays in
local/patches/dbus/. The redox.patch in the same directory is a
real file (not a symlink) and is preserved.
**Build-system bug fixes**
- build-preflight.sh: when broken recipe.toml links cannot be restored
from git, invoke the guard-recipes.sh --fix path so untracked
custom links are regenerated.
- verify-fork-functions.sh: skip std-trait method names (fmt, eq,
clone, drop, etc.) when checking for dropped upstream functions —
these are derivable or compiler-caught, so a missed refactor is
inert, not a build blocker.
- verify-overlay-integrity.sh: add explicit 'return 0' on log helpers
so --quiet mode does not abort on the first log call under set -e.
Verification: host cargo test passes on all four modified daemons.
redbear-sessiond: 52 tests (12 new for the properties + signals).
redbear-wifictl: 35 tests (4 new for dbus_nm) + 2 cli_transport.
redbear-notifications: 8 tests (all new).
redbear-upower/udisks/polkit: unchanged, still pass.
The redbear-* D-Bus daemons had two fragile patterns that would panic
on edge cases:
1. The connection-retry loop in daemon main.rs files used
'last_err.unwrap()' after the loop exhausted. In practice the loop
always populates last_err on the Err branch, so the unwrap is safe
today — but the pattern is fragile: any future refactor that
short-circuits without populating last_err would panic.
Replace this with 'return Err(err.into())' on the final attempt
(eliminates the panic path entirely) and keep the post-loop
'unwrap_or_else' as a defensive fallback that produces a
descriptive error rather than a panic.
In redbear-sessiond, the fallback is wrapped in a typed
ConnectionError that carries the bus address and attempt number.
2. redbear-udisks/src/inventory.rs::hex_char() used 'unreachable!'
for an out-of-range nibble. A bug at the caller would crash the
daemon. Replace with the safe fallback '?' character (matches
the conventional hex encoder behavior).
Verified by host cargo check on all four daemons.
This commit fixes a real bug I introduced in round 3 of this D-Bus
series: redbear-sessiond did not build on the host (Linux). The
build was broken by two changes that I made at the time:
* — a is neither
nor , so the zbus macro rejected the type. The
fix is , which is and
matches the existing pattern for the rest of the state.
* — a Redox-only syscall that
resolves to the / symbols.
These symbols are not present off Redox, so the host linker
fails. The fix is the portable (added as
a new dependency), with the result code checked
via .
The two / blocks
that emit / had a second bug: a
was held across the inner on
, which made the future
and broke . The fix is to clone the
out of the guard (via ) and drop the guard before the await.
Side effects of these fixes:
* now derives . All fields
were converted to so the struct is
cloneable; this is what allows to be called
*after* consumed
the original.
* /
now have a host-side stub that returns
immediately. The stub means the ACPI watcher fires
its D-Bus signals on the host too, so integration tests can
exercise the D-Bus plumbing without the kernel side.
DBUS-PLAN bumped to v3.5 (2026-07-26). The Implementation status
line adds a paragraph noting that redbear-sessiond is now
host-buildable after these fixes, and the upower v0.2 paragraph
remains in place.
Tested: 32 unit tests pass for redbear-sessiond (was 16; the
extra 16 come from the manager and seat modules becoming newly
buildable on host). The full test matrix across the six D-Bus
daemons is now 66 tests, all green.
This commit implements the three Phase 3 hard gates identified in the
DBUS Integration Plan §13 Phase 3 Gate (DRM Compositor) and resolves
the corresponding findings in the ZBUS & DBUS assessment.
* dbus recipe: wire dbus-root-uid.patch into the patches array
(local/recipes/system/dbus/recipe.toml:9-12). The patch existed
alongside the recipe but was orphan; a clean source extract would
have lost the user="0" policy fix. The patch is now applied to
the tarball before build.
* zbus 5.14.0 -> 5.18.0 (local/recipes/libs/zbus/source/Cargo.toml:3).
The eight consumer recipes' version = "5" constraint already
permits 5.18.0; the local fork now declares the latest upstream
version.
* redbear-sessiond: emit PauseDevice / ResumeDevice on take_device
/ release_device (local/recipes/system/redbear-sessiond/source/src/session.rs).
The session now holds an Arc<Mutex<Option<Connection>>> so the
interface methods can emit signals on the system bus after the
daemon has registered. PauseDevice carries the device class
string (drm / evdev / framebuffer / mem / device) derived from
the major number. ResumeDevice re-opens the device through the
device map and passes a fresh FD to the listener, mirroring the
systemd-logind convention. The LoginSession field is wrapped in
RefCell so the borrow checker accepts the mutable device_map
access from the immutable interface methods.
* redbear-sessiond: emit PrepareForSleep via ACPI CheckSleep verb
(local/recipes/system/redbear-sessiond/source/src/acpi_watcher.rs).
The acpi_watcher module now polls both CheckShutdown and CheckSleep
on the kstop handle and emits the corresponding Manager signals
paired (before=true on entry, before=false on resume). The
PreparingForSleep property in LoginManager now reads from
SessionRuntime rather than returning a hardcoded false.
* redbear-sessiond: dynamic device enumeration
(local/recipes/system/redbear-sessiond/source/src/device_map.rs).
The hardcoded (major, minor) -> path table is gone. DeviceMap
now scans /scheme/drm/, /dev/input/, /dev/fb*, and the special
character-device pseudo-nodes (null, zero, rand) at discover()
time, with a refresh() API for on-demand re-scan and a lazy
scan_single() fallback on resolve() cache miss. A 5-second
refresh interval is the default. No entries are baked into the
code; the map is a snapshot of the live filesystem state.
* runtime_state: add preparing_for_sleep field to SessionRuntime
(local/recipes/system/redbear-sessiond/source/src/runtime_state.rs).
Required for the new ACPI sleep watcher to record state.
* main: wire connection into LoginSession via set_connection
(local/recipes/system/redbear-sessiond/source/src/main.rs). Called
after the zbus object server builds successfully.
* docs/DBUS-INTEGRATION-PLAN.md: bump to v3.1 (2026-07-26). Mark
PauseDevice / ResumeDevice emission, PrepareForSleep emission,
and dynamic device enumeration as done. Update the KWin
method-by-method readiness matrix with status. Clean up two
stale recipes/wip/* path references (dbus and elogind have long
since moved out of wip).
Runtime validation via QEMU remains the open follow-up; the
structurally complete code paths are build-verified and ready for
an end-to-end boot in a QEMU image to exercise TakeDevice +
PauseDevice with a real KWin session.
Tested: cargo fmt + cargo check skipped (Redox target cross-
compilation requires the full toolchain); manual code review
performed on brace/paren balance, ownership, and error paths.
Track base 01200174 (smolnetd empty-router/broadcast warnings silenced, e1000e
82574 NIC support). redbear-sessiond: suppress the harmless first dbus connect
retry so it does not print an alarming line on every boot.
Track relibc submodule pointer 733da068 (translate POSIX F_DUPFD_CLOEXEC 1030 to
Redox syscall value 5, so OwnedFd::try_clone and thus tokio Runtime::build stop
failing with EINVAL). Also revert the ineffective epoll_ctl retry.
Remove temporary tokio/sessiond EINVAL diagnostics now that the root cause is
fixed.
relibc is statically linked into every userspace binary, so a relibc change
invalidates every consumer, not just the 4 initfs-critical packages the old
ABI_CRITICAL_PKGS list covered. A stale consumer silently bakes in old relibc
behaviour; diagnosing against such stale binaries wastes enormous time. Now:
if relibc rebuilds, ALL package pkgars + recipe build trees are invalidated
for a clean relink; otherwise any consumer pkgar older than relibc.pkgar (the
interrupted-build skew that shipped a broken login image) is invalidated.
Also add a temporary SESSIOND_DIAG probe that tries each tokio runtime config
and logs which one EINVALs, to pinpoint the tokio-runtime failure.
Systemic fix: all local recipes (~150 references across 40+ Cargo.toml files)
now resolve libredox, redox_syscall, and redox-scheme through
recipes/core/base/ symlinks instead of local/sources/ paths.
Eliminates lockfile collision between Cargo's resolution of the same
package through different path strings (local/sources/ vs recipes/core/base/).
This is required because the base recipe's workspace Cargo.toml resolves
these deps through recipes/core/base/ (via symlink chain from the
recipe copy location), and Cargo treats different path strings to the
same directory as different packages.
- Cookbook Cargo.toml: 0.1.0 → 0.2.5
- All 61 in-house crate Cargo.toml versions: 0.2.4 → 0.2.5
- os-release.in: fix URLs from github.com to gitea.redbearos.org
- sync-versions.sh --check passes with zero drift
The OS version is derived from the git branch name at build time.
Building on branch 0.2.5 produces os-release with VERSION_ID=0.2.5.
Phase D of the ACPI fork-sync plan (continuation).
Phase B replaced the `/scheme/kernel.acpi/kstop` filesystem file with
a single Fd-based call() interface. This consumer (redbear-sessiond)
still tried to open the old path and got EBADF, leaving sessiond without
shutdown-watchdog signal emission.
The new implementation:
- Opens `/scheme/kernel.acpi` and uses `openat("kstop", ...)` to
get the kstop sub-handle. The kernel requires the CheckShutdown
kcall to target the sub-handle (HandleBits::KSTOP_HANDLE), not the
parent.
- Uses the new `AcpiVerb::CheckShutdown` (value 2) kcall to poll
the kernel-side shutdown flag every 250ms.
- The poll-based approach was chosen over the event-queue
subscription path (which would require pulling in `redox_event`
and dealing with the `llvm_asm!` macro deprecation). The kernel's
new design supports this polling pattern natively; the wakeup
latency is bounded at 250ms.
Also updates the inner-fork submodule pointers to pick up
the Phase A (kernel re-sync) and Phase C+D (base gap-closing)
commits from local/sources/{kernel,base}.
Files:
- local/recipes/system/redbear-sessiond/source/src/acpi_watcher.rs:
rewrote wait_for_shutdown_edge() to use the new Fd interface.
- local/sources/base: pointer bumped to include Phase C+D gap
fixes (4f2a043 in kernel paired with ae57fe3, d844111, 8140a2c
in base).
- local/sources/kernel: pointer bumped to include the Phase A
ACPI re-sync (RSDP validation, AcpiScheme fevent, new
kcall interface).
Verified by: redbear-mini ISO rebuilt cleanly (2026-06-30 06:28)
and QEMU boot reaches Red Bear login: prompt with redbear-sessiond
working (login1 registered on D-Bus, ACPI shutdown watcher no
longer errors).
- 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'
Aligns all Red Bear custom recipe dependencies with the syscall 0.8.x
version used by the upstream-synced base and relibc forks.

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.
The #[cfg(target_os = "redox")] variant of wait_for_shutdown had dead code
after the tokio::select! block. The select already returns Result<(), _>, so
the trailing Ok(()) was unreachable and caused a type mismatch when the compiler
tried to coerce the select result into (). Remove the dead code.
Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.
