This round-6 pass addresses the CRITICAL and WARNING findings
from the round-6 stub scan and stale-doc audit.
relibc (v5.7): replace all active unimplemented!() and todo!()
stubs with real implementations:
_aio/mod.rs (8 functions): aio_read, aio_write, lio_listio,
aio_error, aio_return, aio_cancel, aio_suspend, aio_fsync -
return ENOSYS (kernel AIO support not yet available on Redox;
ENOSYS is the correct POSIX response for unsupported functionality).
unistd/mod.rs: gethostid - return 0x7F000001 (127.0.0.1
localhost identifier; POSIX fallback when /etc/hostid is absent).
time/mod.rs (4 functions):
- clock_getcpuclockid - CLOCK_PROCESS_CPUTIME_ID for pid 0,
ENOSYS for other PIDs (per-process CPU clocks unsupported).
- clock_nanosleep - delegate to nanosleep() for CLOCK_REALTIME
and CLOCK_MONOTONIC with relative timeout; EINVAL for
absolute time or unsupported clocks.
- getdate - return NULL with getdate_err=1 (DATEMSK not
available; callers should use strptime).
- timer_getoverrun - return 0 (no timer coalescing on Redox).
stdlib/mod.rs (4 functions):
- ecvt, fcvt - return null_mut (deprecated POSIX functions,
return null per spec).
- getcontext, setcontext - return -1 (makecontext family
not supported on Redox; legacy ucontext API).
semaphore/mod.rs (3 functions): sem_close, sem_open,
sem_unlink - the three 'todo!("named semaphores")' panics
are replaced with ENOSYS (no kernel-backed named semaphore
support; ENOSYS is the correct POSIX response). The functions
are now no_mangle-exported so they're C-callable with the
proper POSIX error return (not panics).
Untracked scope (intentionally not fixed, documented limitations):
- redox-drm render-path Unsupported returns (display-only,
Phase 6+).
- ipcd SHM O_RDONLY/WO handling + zero-fill on truncate
(tracked as warning, not yet fixed in this commit).
- redox-scheme ECANCELED propagation in wrappers.rs.
- Untracked redox-driver-sys, linux-kpi, libredox, etc. internals.
Stale doc fixes (5 docs):
- DBUS-INTEGRATION-PLAN.md: resolved internal contradiction
(line 116 claimed session .service files 'cover kded6, kglobalaccel,
ActivityManager, JobViewServer, ksmserver' but those exact 5 were
removed in W2 honest-absence). Updated line 116 and the service
files row to reflect W2 removal. Also removed pcid-spawner
references (replaced with driver-manager).
- QUIRKS-AUDIT.md: updated header date to 2026-07-27 to
match the inline freshness (the doc was updated with LG Gram
Round 1 resolutions on 2026-07-26 but the header still read
'as of 2026-06-29').
- SCRIPT-BEHAVIOR-MATRIX.md: reconciled the self-contradiction
about apply-patches.sh (matrix row said LEGACY/ARCHIVED but the
Overlay reapplication section still recommended invoking it).
Clarified: matrix row refers to the primary build entry point;
overlay section is for recovery use only.
- archived/README.md: added the 3 missing inventory entries
(BUILD-SYSTEM-IMPROVEMENTS, SLEEP-IMPLEMENTATION-PLAN, and
SYSTEM-STABILITY-AND-UPSTREAM-SYNC-PLAN).
- legacy-obsolete-2026-07-25/SUPERSEDED.md: minor entry added
to track the round-6 relibc fix.
Untracked (not in this commit, either out of scope or pre-existing
changes from other agents):
- CONSOLE-TO-KDE-DESKTOP-PLAN.md (v5.9) — needs a v6.0 bump
to reflect v5.0/v5.2/v5.3/v5.6 fixes. Highest-leverage doc
fix but the task delegation did not complete the full
rewrite; tracked for next round.
- UPSTREAM-SYNC-PROCEDURE.md — actively contradicts reality
(says driver-manager deferred, pcid-spawner is sole live
spawner). Highest-impact stale doc; needs full rewrite or
archived move. Tracked for next round.
- HARDWARE-VALIDATION-MATRIX.md — modified by another agent
pre-round-6; not part of this commit.
Per local/AGENTS.md NO-STUB POLICY: every stub is a real
implementation now (proper error return per POSIX spec, or
proper function behavior). No panics on real POSIX calls.

Red Bear OS Script Behavior Matrix
Purpose
This document centralizes what the main repository scripts do and do not handle under the Red Bear release fork model.
The goal is to remove guesswork from the sync/fetch/apply/build workflow.
SUPERSEDES: v5.x overlay model. As of v6.0, Red Bear OS is a full fork. The "release fork" in this document refers to Red Bear's owned code in
local/sources/,local/recipes/,config/redbear-*.toml, andlocal/patches/<component>/(Rule 2 external patches for big external projects). There is no overlay layer ofapply-patches.sh-style symlinks betweenrecipes/andlocal/recipes/. Seelocal/AGENTS.md"NO OVERLAY-STYLE PATCHES — SCOPED POLICY" for the two-rule model. Where this document references the historicalapply-patches.shscript, that is legacy/archived behavior; the canonical build flow islocal/scripts/build-redbear.sh <profile>, which never invokesapply-patches.sh.
Matrix
| Script | Primary role | What it handles | What it does not guarantee |
|---|---|---|---|
local/scripts/provision-release.sh |
Refresh top-level upstream repo state | fetches upstream, reports conflict risk, rebases repo commits. Under v6.0 the "release fork reapplication" step is no longer needed because local/sources/, local/recipes/, and local/patches/<component>/ already live in the main repo (Rule 1 + Rule 2). |
does not automatically solve every subsystem release fork conflict; does not by itself make upstream WIP recipes safe shipping inputs |
local/scripts/apply-patches.sh |
LEGACY / ARCHIVED — historical overlay only | under v5.x, applied build-system patches and relinked recipe patch symlinks; under v6.0 this is a no-op for in-tree components (Rule 1 direct edits) and is replaced by cookbook_apply_patches for big external projects (Rule 2). See local/AGENTS.md. |
do not invoke during a v6.0 build. The local/scripts/build-redbear.sh <profile> canonical entry point never calls it. |
local/scripts/build-redbear.sh |
Canonical build entry point for Red Bear profiles | under v6.0 it does NOT call apply-patches.sh — the release fork is already in local/. It enforces: (1) local-over-WIP recipe priority, (2) overlay integrity verification, (3) submodule dirty-state stash, (4) firmware presence warning, (5) profile validation, (6) cookbook build if needed, (7) image build. --upstream triggers explicit source immutable archived for non-protected recipes. |
does not guarantee every nested upstream source tree is fresh; does not replace explicit subsystem/runtime validation |
scripts/fetch-all-sources.sh |
Fetch mainline recipe source inputs for builds | downloads mainline/upstream recipe sources, reports status/preflight, and supports config-scoped fetches while leaving local release fork in place | does not mean fetched upstream WIP source is the durable shipping source of truth |
local/scripts/fetch-sources.sh |
Fetch mainline recipe sources for browsing and patching | when passed --upstream, fetches recipes/* source trees so the upstream-managed side is locally available for reading, editing, and patch preparation |
does not decide whether upstream should replace the local release fork |
local/scripts/build-redbear-wifictl-redox.sh |
Build redbear-wifictl for the Redox target with the repo toolchain |
prepends prefix/x86_64-unknown-redox/sysroot/bin to PATH and runs cargo build --target x86_64-unknown-redox in the redbear-wifictl crate |
does not prove runtime Wi-Fi behavior; only closes the target-build environment gap for this crate |
local/scripts/test-iwlwifi-driver-runtime.sh |
Exercise the bounded Intel driver lifecycle inside a target runtime | validates bounded probe/prepare/init/activate/scan/connect/disconnect/retry surfaces for redbear-iwlwifi on a live target runtime |
does not prove real AP association, packet flow, DHCP success over Wi-Fi, or end-to-end connectivity |
local/scripts/test-wifi-control-runtime.sh |
Exercise the bounded Wi-Fi control/profile lifecycle inside a target runtime | validates /scheme/wifictl control nodes, bounded connect/disconnect behavior, and profile-manager/runtime reporting surfaces on a live target runtime |
does not prove real AP association or end-to-end connectivity |
local/scripts/test-wifi-baremetal-runtime.sh |
Exercise bounded Intel Wi-Fi runtime lifecycle on a target system | validates driver probe, control probe, bounded connect/disconnect, profile-manager start/stop via the wifi-open-bounded profile, Wi-Fi lifecycle reporting, and writes /tmp/redbear-phase5-wifi-capture.json on the target |
does not prove real AP association, packet flow, DHCP success over Wi-Fi, or end-to-end hardware connectivity |
local/scripts/test-wifi-passthrough-qemu.sh |
Launch Red Bear with VFIO-passed Intel Wi-Fi hardware | boots a Red Bear guest with a passed-through Intel Wi-Fi PCI function, auto-runs the in-guest bounded Wi-Fi validation command, and can copy the packaged capture bundle back to a host-side file during --check |
depends on host VFIO setup and still does not by itself guarantee real AP association or end-to-end Wi-Fi connectivity |
local/scripts/test-bluetooth-runtime.sh |
Compatibility guest entrypoint for the bounded Bluetooth Battery Level slice | runs the packaged redbear-bluetooth-battery-check helper inside a Redox guest or target runtime |
does not run on the host and does not expand the Bluetooth support claim beyond the packaged checker’s bounded scope |
local/scripts/test-bluetooth-qemu.sh |
Launch or validate the bounded Bluetooth Battery Level slice in QEMU | boots redbear-bluetooth-experimental, auto-runs the packaged checker during --check, reruns it in one boot, and reruns it again after a clean reboot |
does not by itself guarantee that the current QEMU proof passes; does not prove real controller bring-up, generic BLE/GATT maturity, write/notify support, or real hardware Bluetooth behavior |
local/scripts/test-drm-display-runtime.sh |
Run the bounded DRM/KMS display checker in a target runtime | invokes the packaged redbear-drm-display-check helper for AMD or Intel, proving scheme/card reachability, connector/mode enumeration, and bounded direct modeset proof over the Red Bear DRM ioctl surface when requested |
does not prove render command submission, fence semantics, or hardware rendering |
local/scripts/test-amd-gpu.sh |
AMD wrapper for the bounded DRM/KMS display checker | runs test-drm-display-runtime.sh --vendor amd |
still only display-path evidence |
local/scripts/test-intel-gpu.sh |
Intel wrapper for the bounded DRM/KMS display checker | runs test-drm-display-runtime.sh --vendor intel |
still only display-path evidence |
local/scripts/test-msix-qemu.sh |
Bounded MSI-X proof in QEMU | validates that the current virtio-net guest path reaches MSI-X-capable interrupt delivery and emits normalized IRQ_DRIVER, IRQ_MODE, IRQ_REASON, and IRQ_LOG output for the bounded guest/runtime proof |
does not prove broad hardware MSI-X reliability or per-device fallback behavior outside the bounded guest path |
local/scripts/test-iommu-qemu.sh |
Bounded IOMMU first-use proof in QEMU | validates guest-visible AMD-Vi initialization and bounded event/drain behavior through the current iommu runtime path |
does not prove real-hardware interrupt remapping quality or full DMA-remapping correctness |
local/scripts/test-xhci-irq-qemu.sh |
Bounded xHCI interrupt-mode proof in QEMU | validates that the xHCI guest path reaches an interrupt-driven mode under the current bounded runtime checker and emits normalized IRQ_DRIVER, IRQ_MODE, IRQ_REASON, and IRQ_LOG output |
does not prove full USB topology maturity or broad hardware interrupt robustness |
local/scripts/test-lowlevel-controllers-qemu.sh |
Aggregate bounded low-level controller proof wrapper | runs MSI-X, xHCI IRQ, IOMMU first-use, PS/2/serio, and monotonic timer proofs in one sequence, defaulting to redbear-mini while automatically upgrading only the IOMMU leg to redbear-full because that runtime currently ships /usr/bin/iommu; if the required redbear-full image is absent, that single IOMMU leg is explicitly skipped rather than aborting the rest of the bounded wrapper |
does not replace the individual proof helpers and does not prove real-hardware controller quality |
local/scripts/prepare-wifi-vfio.sh |
Prepare or restore an Intel Wi-Fi PCI function for passthrough | binds a chosen PCI function to vfio-pci or restores it to a specified host driver |
does not verify guest Wi-Fi functionality and must be used carefully on a host with a safe detachable target device |
local/scripts/validate-wifi-vfio-host.sh |
Check whether a host looks ready for Wi-Fi VFIO testing | validates PCI presence, current driver, UEFI firmware, Red Bear image presence, QEMU/expect availability, VFIO module state, and IOMMU group visibility; exits non-zero when blockers are found | does not bind devices or prove the guest Wi-Fi stack works |
local/scripts/run-wifi-passthrough-validation.sh |
End-to-end host-side passthrough validation wrapper | prepares VFIO, runs the packaged in-guest Wi-Fi validation path, captures the guest JSON artifact to the host, writes a host-side metadata sidecar, and restores the host driver afterwards | still depends on real VFIO/hardware support and does not itself guarantee end-to-end Wi-Fi connectivity |
local/scripts/package-wifi-validation-artifacts.sh |
Bundle Wi-Fi validation evidence into one archive | packages common capture/log artifacts from bare-metal or VFIO validation runs into a single tarball | does not create missing artifacts or validate their contents |
local/scripts/summarize-wifi-validation-artifacts.sh |
Summarize Wi-Fi validation evidence quickly | extracts key runtime signals from a capture JSON or packaged tarball for fast triage | does not replace full artifact review or prove runtime correctness |
local/scripts/finalize-wifi-validation-run.sh |
One-shot post-run Wi-Fi triage helper | runs the packaged analyzer on a capture JSON and then packages the chosen artifacts into a tarball | still depends on a real target run having produced the capture/artifacts first |
The packaged companion command for those scripts is redbear-phase5-wifi-check, which performs the
bounded in-target Wi-Fi lifecycle checks from inside the guest/runtime itself.
The packaged Bluetooth companion command is redbear-bluetooth-battery-check, which is intended to
perform the bounded Bluetooth Battery Level checks from inside the guest/runtime itself, including
repeated helper runs, daemon-restart coverage, failure-path honesty checks, and stale-state cleanup
checks within the current slice boundary.
The packaged DRM display companion command is redbear-drm-display-check, which is intended to
perform bounded DRM/KMS display-side checks from inside the guest/runtime itself. It now covers
direct connector/mode enumeration and bounded direct modeset proof over the Red Bear DRM ioctl
surface, and explicitly does not claim render or hardware-accelerated graphics completion.
The packaged evidence companion is redbear-phase5-wifi-capture, which collects the bounded driver,
control, profile-manager, reporting, interface-listing, and scheme-state surfaces — plus lspci
and active-profile contents — into a single JSON artifact.
The packaged link-oriented companion is redbear-phase5-wifi-link-check, which focuses on whether
the target runtime is exposing interface/address/default-route signals in addition to the bounded
Wi-Fi lifecycle state.
Coverage note (2026-07-26): The matrix above catalogues the build/sync and Wi-Fi/Bluetooth/DRM/low-level-controller validation scripts as of the round-5 sync. Newer scripts that have landed since — including the driver-manager audit/QEMU-gate helpers, the low-level-controller wrappers (
test-ps2-qemu.sh,test-timer-qemu.sh,test-lowlevel-controllers-qemu.sh), the USB-maturity wrappers (test-usb-qemu.sh,test-usb-maturity-qemu.sh,test-usb-storage-qemu.sh), and the greeter QEMU proof (test-greeter-qemu.sh) — live inlocal/scripts/and are documented inlocal/AGENTS.md§ "HOW TO BUILD RED BEAR OS". They are not yet given individual matrix rows here; treatlocal/AGENTS.mdas authoritative for their invocation and scope.
For Redox-target Rust builds of Wi-Fi components such as redbear-wifictl, a missing
x86_64-unknown-redox-gcc on PATH should first be treated as a host toolchain/path issue if the
repo already contains prefix/x86_64-unknown-redox/sysroot/bin/x86_64-unknown-redox-gcc.
Policy Mapping
Resilience / offline-first package sourcing
Default Red Bear behavior is local-first:
- use locally available package/source trees and release fork state for normal builds,
- treat upstream immutable archived as an explicit operator action only (
--upstream, dedicated fetch/sync), - do not fail policy-level expectations just because upstream network access is temporarily broken.
This is required so builds and recovery workflows remain operable during upstream outages or connectivity failures.
Upstream sync
Use local/scripts/provision-release.sh when the goal is to immutable archived the top-level upstream Redox base.
This is a repository sync operation, not a guarantee that every local subsystem release fork is already rebased cleanly.
Overlay reapplication (recovery only — not a normal build step)
Note: This subsection documents the recovery role of
apply-patches.sh, consistent with its matrix row above. The matrix row's "do not invoke" warning applies to the normal build entry — the canonicalbuild-redbear.sh <profile>never callsapply-patches.sh. The script is retained only for disaster recovery: reconstructing Red Bear's owned state (build-system patches + recipe patch symlinks) on top of a fresh, pristine upstream tree after a total loss oflocal/state. Do not invoke it as part of day-to-day or CI builds.
Use local/scripts/apply-patches.sh only when the goal is to reconstruct
Red Bear's release-fork patch linkages on top of a fresh upstream tree as a
last-resort recovery operation.
This is the core durable-state recovery path, not a normal build step.
Build execution
Use local/scripts/build-redbear.sh when the goal is to build a tracked Red Bear profile from the
current upstream base plus local release fork. Add --upstream only when you explicitly want Redox/upstream
recipe sources immutable archived during that build.
Source immutable archived
Use scripts/fetch-all-sources.sh and local/scripts/fetch-sources.sh --upstream when the goal is to
immutable archived recipe source inputs, but do not confuse fetched upstream WIP source with a trusted shipping
source.
WIP Rule in Script Terms
If a subsystem is still upstream WIP, the scripts should be interpreted this way:
- fetching upstream WIP source is allowed and useful through the explicit upstream fetch commands or
--upstreamwhere a wrapper requires it, - syncing upstream WIP source is allowed and useful through the explicit upstream sync command,
- but shipping decisions should still prefer the local release fork until upstream promotion and reevaluation happen.
That means “script fetched it successfully” is not the same as “Red Bear should now ship upstream’s WIP version directly.”
