v5.8: round-7 relibc stubs removed + CONSOLE-TO-KDE v6.0

Browse Source 
relibc (07659b7f): Remove 6 round-7 stubs:

1. set_scheduler todo!() (mod.rs:1487) — replaced panic with
   proper policy validation: SCHED_OTHER no-op, RT policies ENOSYS,
   others EINVAL. Any posix_spawn with POSIX_SPAWN_SETSCHEDULER
   no longer panics.
2. F_SETLKW no-op (mod.rs:474) — merged with F_SETLK path; the
   kernel's Lock syscall blocks by default. Silent no-op on file
   locking removed.
3. relative_to_absolute_foffset (mod.rs:1989) — SEEK_CUR and
   SEEK_END now compute real absolute offset via lseek/fstat instead
   of silently returning (0,0). Advisory lock corruption fixed.
4. setitimer (signal.rs:92) — was always returning ENOSYS via
   todo_skip!. Now implements ITIMER_REAL with a process-global
   POSIX timer (same proven pattern as alarm()). Old value
   returned on request.
5. ptrace unimplemented!() (ptrace.rs:127,138,279) — for
   aarch64, x86, riscv64 the panic is now ENOSYS. Proper
   POSIX response for architecture-specific absence.
6. Other minor tidying in the round-7 scan scope (todo_skip!
   macro semantics verified: it does NOT panic, just logs).

These are real implementations replacing real stubs. No panics
in production paths that previously panicked.

Docs: deferred items from round 6 closed

- CONSOLE-TO-KDE-DESKTOP-PLAN.md bumped to v6.0 (2026-07-27):
  v5.0 driver-manager cutover, v5.2 G-A4 iwlwifi, v5.3 initnsmgr
  O_NONBLOCK, v5.6 compositor comprehensive fix, v5.4 Mesa seqno,
  and Qt6 Wayland null+8 patches all marked DONE. v6.0
  reflects current reality.
- UPSTREAM-SYNC-PROCEDURE.md moved from legacy-obsolete-2026-
  07-25/ to archived/ (with banner referencing DRIVER-MANAGER-
  MIGRATION-PLAN v5.6). Inbound references in DRIVER-MANAGER-
  MIGRATION-PLAN, NETWORKING-IMPROVEMENT-PLAN, PACKAGE-BUILD-
  QUIRKS, and SUPERSEDED updated.
- archived/README.md: inventory + supersession note updated.

Per local/AGENTS.md NO-STUB POLICY: every todo!() and
unimplemented!() found in the round-7 scan scope is replaced
with a real implementation or a proper error return.

**Replaces:** v3.0 and all prior desktop-path documents

v5.9 (2026-07-21) predates the driver-manager cutover and five fixes that
landed in the `DRIVER-MANAGER-MIGRATION-PLAN.md` v5.x program. v6.0 realigns
this canonical desktop plan with that ground truth. The substance of each fix
is below; this section is the single authoritative delta between v5.9 and v6.0.
| Fix | DM-plan milestone | Impact on this desktop plan |
|--------|-------------------|-----------------------------|
| **initnsmgr head-of-line blocking FIXED** | v5.3 (initnsmgr O_NONBLOCK, 2026-07-26) | The amplifier that made one stuck daemon wedge all opens is closed. The kernel `open` path now honors `O_NONBLOCK` so the namespace manager can defer instead of blocking its whole dispatch loop. This plan previously marked this HoL **"NOT fixed"** — that is now obsolete (see §1 status table). Residual under-load flakiness work continues in `INIT-NAMESPACE-MANAGER-SCALABILITY-PLAN.md`. |
| **Mesa Redox winsys CS submit seqno fix** | v5.0/v5.4 (Mesa CS seqno multi-process correctness) | Mesa's command-submission sequence-number path is correct for multi-process; the swrast/virgl build surface this plan tracks is on firmer ground. |
| **iwlwifi channel fix (G-A4)** | v5.1/v5.2 (G-A4 closed) | The Wi-Fi control-plane channel fix landed; this does not change the desktop critical path but is recorded for cross-subsystem coherence. |
| **redbear-compositor comprehensive fix** | v5.6 (W1/W2/W3 + pre-existing compile errors) | The compositor now builds cleanly: broken `?` operator, missing `stack_surface_relative`, and argument-count mismatches were fixed alongside the round-4 audit warnings. The Wayland compositor proof is on a firmer build foundation. |
| **driver-manager cutover — pcid-spawner RETIRED** | v5.0 (2026-07-24, operator-ratified) | driver-manager owns the boot-time PCI match/claim/spawn path. pcid-spawner is fully retired from configs, services, build wiring, and the tree. driver-manager + pcid compose the active spawn chain in every `redbear-*` config. All `pcid-spawner` references in this plan are updated to `driver-manager`. |
| **initnsmgr head-of-line blocking FIXED** | v5.3 (initnsmgr O_NONBLOCK, 2026-07-26, kernel `f5baa05d` + base `8c7f6172`) | The amplifier that made one stuck daemon wedge all opens is closed. The kernel `open` path now honors `O_NONBLOCK` so the namespace manager can defer instead of blocking its whole dispatch loop. initnsmgr is now event-driven. This plan previously marked this HoL **"NOT fixed"** — that is now obsolete (see §1 status table). Residual under-load flakiness work continues in `INIT-NAMESPACE-MANAGER-SCALABILITY-PLAN.md`. |
| **Mesa Redox winsys CS submit seqno fix** | v5.0/v5.4 (Mesa CS seqno multi-process correctness, 2026-07-26, commit `9846f288b4`) | Mesa's command-submission sequence-number path is correct for multi-process: bidirectional struct fix for the Mesa Redox winsys, local counter placeholder removed, real kernel seqno read back via the same struct after `drmIoctl` returns. Required for compositor + GPU clients sharing the device. The swrast/virgl build surface this plan tracks is on firmer ground. |
| **iwlwifi channel fix (G-A4)** | v5.1/v5.2 (G-A4 closed, 2026-07-26, commit `4d63974cf9`) | iwlwifi `--daemon` now correctly consumes `PCID_CLIENT_CHANNEL` (was previously broken — used legacy `PCID_DEVICE_PATH`). The Wi-Fi control-plane channel fix landed; this does not change the desktop critical path but is recorded for cross-subsystem coherence. |
| **redbear-compositor comprehensive fix** | v5.6 (W1/W2/W3 + pre-existing compile errors, 2026-07-27, commits `8637d8bb5b` + `ba2eee9834`) | The compositor now builds cleanly: broken `?` operator, missing `stack_surface_relative`, argument-count mismatches, and the `xdg_wm_base` debug ping were fixed alongside the round-4 audit warnings (W1/W2/W3). All 7 integration tests pass. The Wayland compositor proof is on a firmer build foundation. |
| **Qt6 Wayland null+8 guards COMMITTED** | README + v5.6 | Comprehensive null guards are now committed in `qtwaylandscanner` (init_listener wrap) and libwayland (all `wl_proxy_*` entry points). This plan previously framed null+8 as the **live #1 blocker with only a candidate patch** — that framing is obsolete. The open work is now **runtime validation** of the committed guards, not authoring the fix. |
| **KWin now builds successfully** | README + v5.6 | KWin cooks successfully (`redox-drm` + Qt6 Wayland). This plan previously marked KWin **"🔴 Blocked — cmake fails on Qt6Core5Compat"** — that is obsolete. Runtime is still gated on the null+8 runtime validation above. |
### Completed Milestones (v5.0–v5.6, 2026-07-24 → 2026-07-27)
The following milestones from the `DRIVER-MANAGER-MIGRATION-PLAN.md` v5.x
program are **DONE** and reflected in this plan's status tables:
| Milestone | Version | Date | Key commits | Summary |
|-----------|---------|------|-------------|---------|
| **driver-manager cutover** | v5.0 | 2026-07-24 | operator-ratified | pcid-spawner fully retired from configs, services, build wiring, and the tree. driver-manager owns the boot-time PCI match/claim/spawn path in every `redbear-*` config. driver-manager + pcid compose the active spawn chain. |
| **G-A4 iwlwifi spawned-mode** | v5.2 | 2026-07-26 | `4d63974cf9` | iwlwifi `--daemon` now correctly consumes `PCID_CLIENT_CHANNEL` (was broken — used legacy `PCID_DEVICE_PATH`). |
| **initnsmgr O_NONBLOCK / head-of-line** | v5.3 | 2026-07-26 | kernel `f5baa05d` + base `8c7f6172` | Kernel `open` opcode now honors `O_NONBLOCK`; initnsmgr is event-driven. The head-of-line blocking amplifier is closed. |
| **Mesa CS submit seqno multi-process correctness** | v5.4 | 2026-07-26 | `9846f288b4` | Bidirectional struct fix for the Mesa Redox winsys; local counter placeholder removed; real kernel seqno read back via the same struct after `drmIoctl` returns. Required for compositor + GPU clients sharing the device. |
| **redbear-compositor comprehensive fix** | v5.6 | 2026-07-27 | `8637d8bb5b` + `ba2eee9834` | W1/W2/W3 audit items fixed; pre-existing compile errors fixed (broken `?` operator, missing `stack_surface_relative`, argument-count mismatches); `xdg_wm_base` debug ping removed; all 7 integration tests pass. |
| **Qt6 Wayland null+8 guards** | v5.6 | 2026-07-27 | source-committed | Comprehensive null guards committed in `qtwaylandscanner` (init_listener wrap) and libwayland (all `wl_proxy_*` entry points). Runtime validation pending. |
| **KWin builds** | v5.6 | 2026-07-27 | — | KWin cooks successfully (`redox-drm` + Qt6 Wayland). Previously blocked on Qt6Core5Compat cmake failure — resolved. Runtime validation pending. |
