ROOT CAUSE: Qt6's auto-generated Wayland wrappers pass NULL proxies
to wl_*_add_listener() during initialization. The generated code stores
wlRegistryBind() return value in m_wl_* member without null check,
then init_listener() calls wl_*_add_listener(m_wl_*, ...) which
page-faults at null+8 (write to proxy->object.implementation).
FIX (kded6): wrapper script renames libqwayland.so to .disabled
before launching kded6.real. QT_QPA_PLATFORM=offscreen alone is not
sufficient — Qt6 still loads wayland plugin despite env var.
FIX (libwayland): null guards in redox.patch for wl_proxy_add_listener,
wl_proxy_get_version, wl_proxy_get_display. Blocked from compilation
by pre-existing relibc conflicts (open_memstream, signalfd_siginfo).
FIX (Qt6 wrappers): regex-based null guard insertion proven in concept.
Blocked by TOML recipe format not supporting backslash escape sequences.
Implementation plan: inject null guards via a separate build step script
rather than inline in recipe.toml.
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.
Add guard-recipes.sh with four modes:
- --verify: check all local/recipes have correct symlinks into recipes/
- --fix: repair broken symlinks (run before builds)
- --save-all: snapshot all recipe.toml into local/recipes/
- --restore: recreate all symlinks from local/recipes/ (run after sync-upstream)
Wired into apply-patches.sh (post-patch) and sync-upstream.sh (post-sync).
This prevents the build system from deleting recipe files during
cargo cook, make distclean, or upstream source refresh.
Verified x86_64-unknown-redox cross-compilation:
redbear-hwutils, redbear-info, redbear-compositor all build and publish.
Host cargo check zero warnings. Target make r.* successful.
12 total commits. 7 master plan workstreams advanced.
- count_status: cfg-gated to Redox only (uses CheckStatus)
- list_dir_names: cfg-gated to Redox only (uses std::fs)
Verified: host cargo check zero warnings, Redox-target make r.redbear-hwutils
builds and publishes successfully (x86_64-unknown-redox).
- redbear-phase-pci-irq-check: removed Copy derive from AffinityProbe
(contains String field, not Copy-safe on Redox target)
- redbear-phase1-udev-check: added missing count_status() function
Verified: make r.redbear-hwutils builds and publishes successfully
for x86_64-unknown-redox target.
test-posix-runtime.sh: unified POSIX runtime harness running all 6
relibc-phase1-tests C programs in guest/QEMU modes, exit-code-based
redbear-usb-check.rs: recreated after cancelled task cleanup —
full Phase-pattern checker with JSON output, xHCI/USB/HID/storage probes
Zero warnings, all scripts syntax-clean.
redbear-usb-check: rewritten from 99-line minimal checker to full
Phase-pattern validation (CheckResult/Report, JSON output, proper
cfg-gating). Checks xHCI controllers, USB device enumeration,
HID class detection, storage class detection.
test-usb-runtime.sh: guest + QEMU harness following Phase 1-5 pattern.
Zero warnings.
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.
