Subject: [PATCH 04/54] modules/kexec-tools + kexec-boot: bump to upstream
 commit e18a71f..., add versioned patches and Xen syscall loader

- Prefer upstream commit e18a71f... for kexec-tools; add versioned patches in patches/kexec-tools-e18a71f... (disable vmcore, framebuffer improvements, purgatory/build fixes, util build fixes).
- Update module to use commit-based module directory, switch to -Oz build flags and add zstd dependency to ensure proper upstream build with GCC 15.1.
- Update initrd/bin/kexec-boot to use syscall-only loader for Xen, use --load consistently, and remove buggy -d debug-load option.

From 465ddbcd703e808e177711f16495b95aaef81a81 Mon Sep 17 00:00:00 2001
From: Thierry Laurion <insurgo@riseup.net>
Date: Fri, 23 Jan 2026 16:58:37 -0500
Subject: [PATCH 06/54] gpg2: sync toolstack and modules for GCC15/-Oz
 compatibility

- Replace per-module hardcode_into_libs patches with inline sed calls in modules: libgcrypt, libksba, libassuan
- Update modules: libgcrypt, libksba, libassuan, libgpg-error, libusb, gpg2, pinentry, libusb-compat; enforce -Oz and other compatibility tweaks
- Add patch: patches/gpg2-2.4.0.patch
- Delete obsolete patches for libassuan-2.5.5, libgcrypt-1.10.1/1.10.2/1.8.3, libksba-1.3.5/1.6.3

Signed-off-by: Thierry Laurion <insurgo@riseup.net>

Subject: [PATCH 07/54] modules/dropbear + patches/dropbear-2025.88: sync with
 tlaurion staging; add patch to avoid fatal user/group change errors in Heads

Document GCC 15.1 bump requirement and partial -Oz support.

Notes:
- This update syncs the module and adds a patch that prevents Dropbear from exiting on user/group change failures in Heads.
- The toolchain bump to GCC 15.1 was required for compatibility and enabled -Oz usage in parts of the build.
- -Oz support is partial: Dropbear's main build uses -Oz while the bundled libtommath is built with -Os (controlled via LTM_CFLAGS/DROPBEAR_LTM_CFLAGS); further flag exploration is recommended before wide-sweeping changes.

Subject: [PATCH 08/54] modules/*: Gcc 15.1 + Oz fixes

- patches/patches/bash-5.1.16.patch
- What was missing in the per-dir patch (vs the branch/origin/master canonical patch):
  - added missing '#include <unistd.h>' to 'lib/termcap/tparam.c' to fix the implicit 'write' declaration under GCC 15.1.
  - updated 'Makefile.in' (mkversion invocation tweak)
- adjusted many modules' CFLAGS to prefer '-Oz' and added '-std=gnu11' where necessary to address C23 keyword and type compatibility issues surfaced by GCC 15.1;
- added/fixed module patches for PowerPC and other modules (see patch list in commit diff).

Subject: [PATCH 09/54] modules/linux: ppc64 GCC 15.1 compatibility flags
 (mitigation for assembler/codegen issues)

Add PowerPC-specific EXTRA_FLAGS to reduce aggressive optimizations and force -std=gnu11 for C23 compatibility when building on ppc64 with GCC 15.1.0. This is a mitigation pending an upstream toolchain/binutils fix.

Subject: [PATCH 11/54] modules/dropbear: run configure as a cross build (use
 $(CROSS_TOOLS) + --host)

Run configure with $(CROSS_TOOLS) and --host $(MUSL_ARCH)-linux-musl so Autotools treats this as a cross build and does not probe the host compiler. This avoids configure enabling host-only hardened flags (e.g. -mfunction-return=thunk, -mindirect-branch=thunk) that the ppc64 cross-compiler rejects, which previously caused build failures.

Subject: [PATCH 12/54] patches/powerpc-utils: remove obsolete AC_FUNC_MALLOC
 change; add RTAS function-pointer signature fix

Removed:
- patches/powerpc-utils-1.3.5.patch (dropped AC_FUNC_MALLOC change).
 - This removal was not needed to address the GCC15 compile errors and can cause malloc->rpl_malloc substitutions that break linking.

Added:
- patches/powerpc-utils-1.3.5/0001-fix-rtas-function-pointer-signatures-gcc15.patch.
  - Updates RTAS helper function pointer declarations to match their actual signatures (parse_rtas_event, rtas_print_event, cleanup_rtas_event) to satisfy GCC 15/C23 stricter type checks and fix compilation failures in src/nvram.c.

Subject: [PATCH 13/54] OFLAG audit: confirm and record hardcoded optimization
 flags (2026-01-27)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
- This commit records the results of a deterministic log sweep for optimization flags and updates module `TODO(-OFLAG)` notes, the `build_OFLAG_inventory.csv`, and `OFLAG_PROGRESS.md`.

Confirmed offenders (evidence in build logs):
- slang: hardcoded -O2 (166 occurrences) — propose small packaging patch to remove/override -O2
- tpmtotp: hardcoded -O3 (142 occurrences) sometimes mixed with -Oz (144) — prepare patch to remove -O3
- zlib: hardcoded -O3 (62 occurrences) — prepare patch to remove -O3
- npth: hardcoded -O2 (30 occurrences) — patch to remove -O2
- pciutils: hardcoded -O2 (49 occurrences) — patch to remove -O2
- kexec-tools: mixed -Os/-O2/-Oz (O2:4, Os:18, Oz:87) — normalize to -Oz
- libaio: hardcoded -O2 (4 occurrences) — remove -O2
- tpm2-tss: hardcoded -O2 (8 occurrences) — remove -O2
- tpm2-tools: hardcoded -O2 (1 occurrence) — remove -O2
- cryptsetup2: bundled Argon2/Blake2 set -O3 — existing patch present: patches/cryptsetup2-2.6.1.patch (apply and verify)
- kbd: mix of -O2 and -Oz (O2:1 / Oz:2) — remove -O2 occurrences
- linux/coreboot: kernel/coreboot subcomponents show non -Oz flags (see per-arch logs)

Notes:
- Modules with no logs were marked UNKNOWN (explicit) and left for targeted rebuilds to collect missing logs.
- musl-cross-make and blob placeholders (coreboot-blobs, purism-blobs) marked N/A as they are buildstack/tooling or binary assets.

Action items:
1. Prepare minimal patches for the high-priority offenders listed above and run cross-target builds (x86_64 & ppc64le) to validate.
2. Generate logs for UNKNOWN modules via targeted builds and update statuses.
3. When patches are verified, update module TODOs with patch references and mark as resolved.

This commit is purely audit/documentation and module TODO updates; no build-system behavior was changed beyond annotations and the inventory CSV and tracker update.

 size regression vs older CircleCI artifact

- normalize -O/ -Os -> -Oz only at packaging time
- observed size regression (dropbear +56 KiB, ssh +56 KiB); note local GCC 15.1.0 vs remote GCC 9.4.0

also dropped old unused patch

TODO: further optimizations?

We intentionally do **not** strip `-funroll-loops` or `-fomit-frame-pointer` here — reintroducing those options into bundled libs did not change the final `dropbear`/`ssh` sizes in our experiments. Validated V=1: configure and build logs show `-Oz` for the main build, but a size regression remains versus an earlier CircleCI artifact (dropbear: 184,832 → 241,248; ssh: 176,416 → 233,048, both ≈ +56 KiB). Local builds use GCC 15.1.0 while the earlier artifact used GCC 9.4.0, so the most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags. Action: retain the minimal, reversible sed (creates `.bak`) for reproducibility; record this regression in `build_OFLAG_inventory.csv` and `doc/OFLAG_fixes.md` for future follow-up (possible experiments: rebuild with GCC 9.4, symbol/section diffs, or linker-level mitigations). Priority: Low.

+# OFLAG status: addressed — packaging-time normalization applied to autotools inputs
+# Actions taken:
+#  - Applied in-place `sed -i` normalization to `configure.ac` and `m4/*` to replace `-O[0-9]+` and `-Os` with `-Oz` and to collapse duplicate `-Oz` tokens.
+#  - Avoided editing generated `configure` in-place to prevent corrupting embedded scripts/backreferences; instead we edit autotools inputs and run `autoreconf`.
+#  - Set `hardcode_into_libs=yes` -> `no` to avoid hardcoding lib paths into installed `.la` artifacts.
+# Validation & repro:
+#  - Full verbose board build (V=1) completed and `build/x86/log/tpm2-tss.log` shows compile invocations using `-Oz` and **no** `-O2` in effective compile/link lines.
+#  - Residual `-O2` occurrences remain only in autotools caches/traces (e.g. `autom4te.cache/*`, `configure~`), which are informational and do not affect actual compile commands.
+# Next steps:
+#  - Optionally run `make BOARD=XYZ tpm2-tss V=1` to validate package-only behavior and ensure regenerated files remain normalized; otherwise consider this module ready for committing the packaging-time edits.
+# Inventory classification: fixed — packaging-time sed applied; validated (no -O2 in compile lines; -Oz present)
 
-# TODO(-OFLAG): OFLAG status: CONFIRMED — hardcoded -O2 (8 occurrences) observed in `tpm2-tss` compile/link lines, preventing `CFLAGS=-Oz` from taking effect.
-# Action: add a minimal packaging patch to remove explicit `-O2` from configure/Makefile fragments (or ensure packaging overrides it); verify via cross-arch builds. Priority: Medium.
-# Inventory classification: hardcoded -O2 (8 occurrences)

Subject: [PATCH 28/54] docker: unify helpers; programmatic X11 auth; enable
 USB passthrough by default and kvm

- Centralize Docker logic in docker/common.sh with build_docker_opts() and run_docker() to remove duplication across wrappers.
- Implement programmatic Xauthority (via xauth) and avoid automatic xhost changes; provide concise guidance when Xauthority isn't present.
- Enable host USB passthrough by default when /dev/bus/usb exists; opt-out via HEADS_DISABLE_USB=1
- Auto-add /dev/kvm when present; mount host repo at /root/heads and set HOME=/root.
- Make run_docker print concise feature summary and full docker command for developer visibility; add usage docs for minimal env vars.
- Add safety checks, set -euo pipefail, and trap SIGINT; validate via bash

+OFALG fixes summary
+
+This document lists recent OFLAG (optimization flag) fixes applied in the repository and where to find validation evidence.
+
+- zlib
+  - Fix: packaging enforces CFLAGS=-Oz
+  - Validation: V=1 builds on x86 & ppc64 show -Oz usage in compile lines
+  - Logs: build/x86/log/zlib.log, build/ppc64/log/zlib.log
+
+- cryptsetup2
+  - Fix: pre-configure substitutions applied (remove -O3 from Argon2 templates and normalize libtool hardcode flags)
+  - Commit: fac65ebc7e
+  - Validation: V=1 x86 build validated; grep shows no remaining -O3 in cryptsetup build tree
+  - Logs: build/ppc64/log/cryptsetup2.log, build/x86/log/cryptsetup2.log
+
+- slang
+  - Fix: minimal pre-configure sed applied replacing -O2 with -Oz
+  - Validation: logged CFLAGS show -Oz in build output
+  - Logs: build/x86/log/slang.log
+
+- libaio
+  - Fix: pre-configure sed applied to replace `-O[0-9]+` and `-Os` with `-Oz`.
+  - Validation: V=1 x86 & ppc64 builds show `-Oz` in compile and link lines (see `build/x86/log/libaio.log` and `build/ppc64/log/libaio.log`).
+
+- tpmtotp
+  - Fix: guarded pre-build sed replaces -O[0-9]+ with -Oz in generated Makefile fragments (Makefile, util/Makefile, libtpm/Makefile)
+  - Validation: V=1 builds completed for x86 & ppc64 and grep shows no remaining -O3 in build trees
+  - Logs: build/x86/log/tpmtotp.log, build/ppc64/log/tpmtotp.log
+
+- dropbear
+  - Fix: packaging-time sed normalizes optimization flags to `-Oz` (replaces `-O[0-9]+` & `-Os` with `-Oz`) and configure is invoked with size-friendly env vars where applicable. We intentionally do not strip `-funroll-loops`/`-fomit-frame-pointer` at packaging time because reintroducing them into bundled libs did not change final binary sizes in our tests.
+  - Validation: V=1 x86 build shows `-Oz` in `configure` and build logs. However, a size regression was observed versus the earlier CircleCI artifact: `dropbear` 184,832 → 241,248 (+56,416 bytes), `ssh` 176,416 → 233,048 (+56,632 bytes). Local builds used GCC 15.1.0 while the earlier artifact used GCC 9.4.0; most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags.
+  - Logs: build/x86/dropbear-2025.88/config.log
+  - Recommended follow-ups: 1) Rebuild dropbear under GCC 9.4 to confirm toolchain impact; 2) run symbol/section diffs to localize growth; 3) prototype linker/build mitigations (`-ffunction-sections/-fdata-sections` + `--gc-sections`, strip, or LTO) if desired.
+
+Notes & next steps
+- .bak files left in the build trees are artifacts of the reversible sed step; remove them for cleanliness if desired or keep them as audit evidence.
+- For cross-arch completeness, consider running per-package V=1 builds on additional arches (arm64, riscv) for packages that still show legacy -O tokens in non-built files.

   - Logs: build/x86/dropbear-2025.88/config.log
   - Recommended follow-ups: 1) Rebuild dropbear under GCC 9.4 to confirm toolchain impact; 2) run symbol/section diffs to localize growth; 3) prototype linker/build mitigations (`-ffunction-sections/-fdata-sections` + `--gc-sections`, strip, or LTO) if desired.

+  - Fix: packaging-time pre-configure sed normalizes `-O[0-9]+`/`-Os` -> `-Oz` and removes Makefile backup artifacts; sed is run during `kexec-tools_configure` (pre-configure) so generated artifacts no longer contain legacy `-O` tokens.
+  - Validation: V=1 x86 & ppc64 builds show `-Oz` only in compile/link lines; evidence: `build/x86/log/kexec-tools.log`, `build/ppc64/log/kexec-tools.log`. Post-scan totals: `Oz:157`, no `-O2`/`-Os` occurrences remaining in build logs.
+  - Notes: prior scan reported mixed `-Os`/`-O2`/`-Oz`; packaging-time change resolved those mixed occurrences in validated builds.
+
 Notes & next steps
 - .bak files left in the build trees are artifacts of the reversible sed step; remove them for cleanliness if desired or keep them as audit evidence.
 - For cross-arch completeness, consider running per-package V=1 builds on additional arches (arm64, riscv) for packages that still show legacy -O tokens in non-built files.

   - Fix: packaging-time sed normalizes optimization flags to `-Oz` (replaces `-O[0-9]+` & `-Os` with `-Oz`) and configure is invoked with size-friendly env vars where applicable. We intentionally do not strip `-funroll-loops`/`-fomit-frame-pointer` at packaging time because reintroducing them into bundled libs did not change final binary sizes in our tests.
   - Validation: V=1 x86 build shows `-Oz` in `configure` and build logs. However, a size regression was observed versus the earlier CircleCI artifact: `dropbear` 184,832 → 241,248 (+56,416 bytes), `ssh` 176,416 → 233,048 (+56,632 bytes). Local builds used GCC 15.1.0 while the earlier artifact used GCC 9.4.0; most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags.

 - .bak files left in the build trees are artifacts of the reversible sed step; remove them for cleanliness if desired or keep them as audit evidence.
 - cryptsetup (legacy module) restored to HEAD and is not referenced by any boards; no packaging-time changes are required for that module.
 - For cross-arch completeness, consider running per-package V=1 builds on additional arches (arm64, riscv) for packages that still show legacy -O tokens in non-built files.

Subject: [PATCH 40/54] collect_oflags.py: avoid sed/configure false positives;
 skip per-module configure logs; regenerate built-only CSVs

Details:
- Ignore text after '|' (pipelines) and skip sed substitution contexts for generic '-O' counting to reduce false positives.
- Skip '*.configure.log' and 'configure.*' so only built module logs are scanned.
- Regenerated built-only CSVs: build_oflags_summary_built_only*.csv and updated combined CSVs.

From 13642fae49f6b4b02ba998eca80de7b394cb2dca Mon Sep 17 00:00:00 2001
From: Thierry Laurion <insurgo@riseup.net>
Date: Mon, 2 Feb 2026 17:08:44 -0500
Subject: [PATCH 41/54] modules: canonicalize '# OFLAG:' comments and mark
 untested modules

- Standardize per-module '# OFLAG:' comments to reflect packaging-time '-Oz' enforcement, pre-configure sed normalization, or 'Untested' status.
- Mark modules that had no build logs in the retest as 'Untested in prior retest'.
- Update documentation and remove generated audit CSVs.
- Delete leftovers oflags tracking files
- Delete forgotten files in past testing

Signed-off-by: Thierry Laurion <insurgo@riseup.net>

 - Kernel config note (moved)
   - Note: kernel-config changes to enable `CONFIG_TMPFS` and `CONFIG_MEMFD_CREATE` have been applied repository-wide; see the header comment in `initrd/bin/kexec-boot` for rationale and validation guidance.
+
+Sed normalization patterns
+- Generic pre-configure sed applied across multiple modules normalizes optimization flags to `-Oz`:
+  - Pattern: `sed -e 's/-O[0-9]\+/-Oz/g' -e 's/-Os/-Oz/g'`
+  - Effect: replaces `-O0`, `-O1`, `-O2`, `-O3`, `-Ofast` with `-Oz` and replaces `-Os` with `-Oz` in generated configure scripts and Makefiles.
+  - Placement: applied in `module_configure` target before `./configure` invocation or in pre-build hooks.
+  - Artifact cleanup: `.bak` files generated by sed are removed to avoid confusion with source artifacts.
+
+Notes:
+- `openssl` — Verified OK: packaging explicitly sets `CFLAGS="-Oz"` in `modules/openssl` and built logs (`build/x86/log/openssl.log`) show compile commands with `-Oz` only. No packaging-time sed changes required.
+- All fixes validated with V=1 reproducible builds (x86 & ppc64) and rescanned using `scripts/collect_oflags.py` to confirm no `-O2`/`-O3` in built module logs.

-# FIXED(-OFLAG): packaging-time sed normalizes optimization flags to `-Oz` only (replaces `-O[0-9]+` and `-Os` with `-Oz`). We intentionally do **not** strip `-funroll-loops` or `-fomit-frame-pointer` here — reintroducing those options into bundled libs did not change the final `dropbear`/`ssh` sizes in our experiments. Validated V=1: configure and build logs show `-Oz` for the main build, but a size regression remains versus an earlier CircleCI artifact (dropbear: 184,832 → 241,248; ssh: 176,416 → 233,048, both ≈ +56 KiB). Local builds use GCC 15.1.0 while the earlier artifact used GCC 9.4.0, so the most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags. Action: retain the minimal, reversible sed (creates `.bak`) for reproducibility; record this regression in `build_OFLAG_inventory.csv` and `doc/OFLAG_fixes.md` for future follow-up (possible experiments: rebuild with GCC 9.4, symbol/section diffs, or linker-level mitigations). Priority: Low.

-#  - Applied in-place `sed -i` normalization to `configure.ac` and `m4/*` to replace `-O[0-9]+` and `-Os` with `-Oz` and to collapse duplicate `-Oz` tokens.
-#  - Avoided editing generated `configure` in-place to prevent corrupting embedded scripts/backreferences; instead we edit autotools inputs and run `autoreconf`.
-#  - Set `hardcode_into_libs=yes` -> `no` to avoid hardcoding lib paths into installed `.la` artifacts.
-# Validation & repro:
-#  - Full verbose board build (V=1) completed and `build/x86/log/tpm2-tss.log` shows compile invocations using `-Oz` and **no** `-O2` in effective compile/link lines.
-#  - Residual `-O2` occurrences remain only in autotools caches/traces (e.g. `autom4te.cache/*`, `configure~`), which are informational and do not affect actual compile commands.

-#  - Optionally run `make BOARD=XYZ tpm2-tss V=1` to validate package-only behavior and ensure regenerated files remain normalized; otherwise consider this module ready for committing the packaging-time edits.

Subject: [PATCH 48/54] modules/dropbear: document -Oz normalization and record
 size regression vs older CircleCI artifact

- normalize -O/ -Os -> -Oz only at packaging time
- observed size regression (dropbear +56 KiB, ssh +56 KiB); note local GCC 15.1.0 vs remote GCC 9.4.0

also dropped old unused patch

TODO: further optimizations?

+# See other modules for examples: e.g., modules/gpg2
+#
+# NOTE: -Oz support here is partial — verbose builds show the main dropbear
+#       compilation using -Oz while the *bundled* libtommath is built with
+#       -Os (configurable via LTM_CFLAGS/DROPBEAR_LTM_CFLAGS). If you need
+#       further size tuning or to hunt GCC15 regressions, explore the
+#       libtommath/libtomcrypt flag variables (LTM_CFLAGS/LTC_CFLAGS) first.
+#
+# FIXED(-OFLAG): packaging-time sed normalizes optimization flags to `-Oz` only (replaces `-O[0-9]+` and `-Os` with `-Oz`). We intentionally do **not** strip `-funroll-loops` or `-fomit-frame-pointer` here — reintroducing those options into bundled libs did not change the final `dropbear`/`ssh` sizes in our experiments. Validated V=1: configure and build logs show `-Oz` for the main build, but a size regression remains versus an earlier CircleCI artifact (dropbear: 184,832 → 241,248; ssh: 176,416 → 233,048, both ≈ +56 KiB). Local builds use GCC 15.1.0 while the earlier artifact used GCC 9.4.0, so the most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags. Action: retain the minimal, reversible sed (creates `.bak`) for reproducibility; record this regression in `build_OFLAG_inventory.csv` and `doc/OFLAG_fixes.md` for future follow-up (possible experiments: rebuild with GCC 9.4, symbol/section diffs, or linker-level mitigations). Priority: Low.
+#
+# NOTE: network support under Heads is seldom used. The `#network-recovery-init`
+#       hook (when present) is currently the main place that invokes dropbear
+#       manually. Consider whether forcing -Oz globally for Dropbear is worth
+#       pursuing if network-recovery is not in active use.
+#
+# TODO: Revisit and document any further flag experiments or required
+#       compatibility fixes before widening -Oz usage elsewhere.
+# Force main build to use -Oz and prefer -Oz for the bundled libtommath.
+# This keeps main dropbear space-optimised while avoiding O3 for libtommath.
+# Use Autotools' cross-compile mechanism so configure knows it's a cross
+# build and won't probe the host compiler for runtime-only hardened flags.
+# Use $(CROSS_TOOLS) so CC and other crosstools are set consistently.

+#  - Avoided editing generated `configure` in-place to prevent corrupting embedded scripts/backreferences; instead we edit autotools inputs and run `autoreconf`.
+#  - Set `hardcode_into_libs=yes` -> `no` to avoid hardcoding lib paths into installed `.la` artifacts.
+# Validation & repro:
+#  - Full verbose board build (V=1) completed and `build/x86/log/tpm2-tss.log` shows compile invocations using `-Oz` and **no** `-O2` in effective compile/link lines.
+#  - Residual `-O2` occurrences remain only in autotools caches/traces (e.g. `autom4te.cache/*`, `configure~`), which are informational and do not affect actual compile commands.

+#  - Optionally run `make BOARD=XYZ tpm2-tss V=1` to validate package-only behavior and ensure regenerated files remain normalized; otherwise consider this module ready for committing the packaging-time edits.

 - dropbear
-  - Fix: packaging-time sed normalizes optimization flags to `-Oz` (replaces `-O[0-9]+` & `-Os` with `-Oz`) and configure is invoked with size-friendly env vars where applicable. We intentionally do not strip `-funroll-loops`/`-fomit-frame-pointer` at packaging time because reintroducing them into bundled libs did not change final binary sizes in our tests.
-  - Validation: V=1 x86 build shows `-Oz` in `configure` and build logs. However, a size regression was observed versus the earlier CircleCI artifact: `dropbear` 184,832 → 241,248 (+56,416 bytes), `ssh` 176,416 → 233,048 (+56,632 bytes). Local builds used GCC 15.1.0 while the earlier artifact used GCC 9.4.0; most likely root cause is compiler/toolchain or upstream package-version changes rather than residual `-O` flags.

+  - Validation: V=1 x86 build shows `-Oz` in configure and build logs; a size regression vs an older CircleCI artifact was observed (investigate toolchain vs package changes).
   - Logs: build/x86/dropbear-2025.88/config.log
-  - Recommended follow-ups: 1) Rebuild dropbear under GCC 9.4 to confirm toolchain impact; 2) run symbol/section diffs to localize growth; 3) prototype linker/build mitigations (`-ffunction-sections/-fdata-sections` + `--gc-sections`, strip, or LTO) if desired.
 
 - kexec-tools
-  - Fix: packaging-time pre-configure sed normalizes `-O[0-9]+`/`-Os` -> `-Oz` and removes Makefile backup artifacts; sed is run during `kexec-tools_configure` (pre-configure) so generated artifacts no longer contain legacy `-O` tokens.
-  - Validation: V=1 x86 & ppc64 builds show `-Oz` only in compile/link lines; evidence: `build/x86/log/kexec-tools.log`, `build/ppc64/log/kexec-tools.log`. Post-scan totals: `Oz:157`, no `-O2`/`-Os` occurrences remaining in build logs.
-  - Notes: prior scan reported mixed `-Os`/`-O2`/`-Oz`; packaging-time change resolved those mixed occurrences in validated builds.

 Notes & next steps
-- .bak files left in the build trees are artifacts of the reversible sed step; remove them for cleanliness if desired or keep them as audit evidence.
-- cryptsetup (legacy module) restored to HEAD and is not referenced by any boards; no packaging-time changes are required for that module.
+- `.bak` files left in the build trees are artifacts of the reversible sed step; remove them for cleanliness if desired or keep them as audit evidence.
 - For cross-arch completeness, consider running per-package V=1 builds on additional arches (arm64, riscv) for packages that still show legacy -O tokens in non-built files.
-
-- Kernel config note (moved)
-  - Note: kernel-config changes to enable `CONFIG_TMPFS` and `CONFIG_MEMFD_CREATE` have been applied repository-wide; see the header comment in `initrd/bin/kexec-boot` for rationale and validation guidance.
+- Kernel config note: changes to enable `CONFIG_TMPFS` and `CONFIG_MEMFD_CREATE` have been applied repository-wide; see the header comment in `initrd/bin/kexec-boot` for rationale and validation guidance.
 
 Sed normalization patterns
 - Generic pre-configure sed applied across multiple modules normalizes optimization flags to `-Oz`:
   - Pattern: `sed -e 's/-O[0-9]\+/-Oz/g' -e 's/-Os/-Oz/g'`
-  - Effect: replaces `-O0`, `-O1`, `-O2`, `-O3`, `-Ofast` with `-Oz` and replaces `-Os` with `-Oz` in generated configure scripts and Makefiles.
   - Placement: applied in `module_configure` target before `./configure` invocation or in pre-build hooks.
-  - Artifact cleanup: `.bak` files generated by sed are removed to avoid confusion with source artifacts.
-
-Notes:
-- `openssl` — Verified OK: packaging explicitly sets `CFLAGS="-Oz"` in `modules/openssl` and built logs (`build/x86/log/openssl.log`) show compile commands with `-Oz` only. No packaging-time sed changes required.
-- All fixes validated with V=1 reproducible builds (x86 & ppc64) and rescanned using `scripts/collect_oflags.py` to confirm no `-O2`/`-O3` in built module logs.
+  - Artifact cleanup: `.bak` files generated by sed are kept or removed per module policy (kept for audit evidence by default).
