From 45519d7eeeefd076bc226fee9defb92078fe7569 Mon Sep 17 00:00:00 2001 From: kartikey1306 Date: Fri, 28 Aug 2026 19:17:52 +0530 Subject: [PATCH 1/8] fix: restore the build and make the unit suite exercise real code master does not compile. Several PRs that fixed the same defects, or that added new files, were squash-merged on stale bases, and nothing re-verified master afterwards -- `CI - eBoot` has been red since. Build breakage: - core/recovery.c declared `slot_size` twice (#33 and #50 both landed the same bounds check). - include/eos_image.h declared `int eos_crc32(uint32_t, size_t, uint32_t *)` while core/image_verify.c defines `uint32_t eos_crc32(uint32_t, size_t)` (#38 vs #52). The header now matches the implementation. - core/sha512.c and core/rollback.c were never added to CMakeLists.txt, so the SHA-512 support from #46 and the anti-rollback counter from #54 were merged as dead code. - Two SHA-512 APIs survived the merge: eos_crypto_boot.h declares eos_sha512_*, include/eos_sha512.h declared sha512_*, and only the latter was implemented. Consolidated on the eos_sha512_* API that the rest of the tree already refers to; include/eos_sha512.h is removed. - The body of eos_ed25519_verify() was lost. What remained was two spliced hash blocks and `return diff == 0` with `diff` undeclared -- the group operation that actually checks the signature was gone. Restored: recompute R' = [S]B + [k](-A) and compare its encoding against R in constant time. - The EBLDR_BOARD dispatch chain was duplicated (83 boards listed twice, 121 lines), with a stray message(FATAL_ERROR ...) spliced into the kalimba branch. tests/unit/test_cmake_board_dispatch.py already covered this. Test suite: - tests/unit/test_slot_manager.c has not compiled since #37, which committed two versions of the file spliced together: a main() calling ~20 functions that do not exist, a duplicated test, and fixture variables used before they are declared. Rebuilt on the coherent pre-#37 harness and given real coverage for the boot-attempt counter #37 was meant to add. - tests/unit/test_boot_log.c defined its own eos_boot_log_* functions, so the linker never pulled core/boot_log.c out of libeboot_core.a: the test exercised its own stubs and reported PASS. Rewritten against the real implementation, stubbing only flash and the tick counter. It now covers append-before-init, head persistence and wrapping, read bounds, and that a failed erase does not reset the head. - include/eos_boot_log.h declared an API that exists nowhere -- init(void), count(), flush(), get_latest(), event_name(). Every one of them lived only in the old test's stubs. The header now documents what core/boot_log.c implements, which is what recovery.c and stage1 already call. - The ARM job in ci.yml pointed CMAKE_TOOLCHAIN_FILE at cmake/arm-cortex-m4.cmake, which does not exist, and passed -DBUILD_TESTS=OFF, which is not this project's option name. Pointed at toolchains/arm-none-eabi.cmake with EBLDR_BOARD=stm32f4. Verified: host build clean in Debug and Release; ctest 16/16 pass; pytest tests/ 13 passed, 1 skipped; `cmake -DEBLDR_BOARD=kalimba` configures. Not verified locally: the ARM cross-build, for lack of an arm-none-eabi toolchain on this machine.

That option defaults to ON, so every cross-compiled board build fails: stage0/jump_stage1.c:70:9: error: unknown type name 'eos_sha256_ctx_t' The host build never caught it because EBLDR_BOARD defaults to "none" and stage0 is only added for a real board -- so the first link in the secure-boot chain, stage-0 verifying stage-1 before jumping to it, has never been compiled. Surfaced by the Cross-compile STM32F4 job on this PR. Verified with `clang -fsyntax-only -DEBLDR_VERIFY_STAGE1` over every stage0/ and stage1/ source: clean afterwards, apart from reset_entry.c's weak aliases, which clang rejects on darwin regardless.

Measured coverage is 23.06%, most of the gap being tests/production_test_suite.py (736 statements) which nothing imports. The step therefore failed on the coverage number even when all 27 Python tests passed -- so this job could never go green regardless of the code. ebuild hit exactly this and resolved it by passing --cov-fail-under=0 in CI, with the reasoning recorded in its .coveragerc: the repo-wide ratchet belongs in codecov.yml, and TESTING.md's 95% target is a patch target, not a repo-wide one. Same fix here, for consistency across the two repos. Both numbers are left alone -- raising .coveragerc to a real floor, or enforcing one here, is a maintainer decision.

Nothing in the tree defined them. tools/embed_stage1_hash.py exists to produce them and is never invoked by the build -- and even if it were, it emitted a header declaring `static const uint8_t stage1_expected_hash`, which cannot satisfy an extern in another translation unit, and never emitted stage1_expected_size at all. So stage-0 verifying stage-1 -- the first link of the secure boot chain, and ON by default via EBLDR_VERIFY_STAGE1 -- has never been built on any board. - tools/embed_stage1_hash.py now emits a C source file defining both symbols with external linkage, sized from the input binary. - CMakeLists.txt generates it from eboot_firmware.bin and compiles it into ebldr_stage0. The custom command DEPENDS on eboot_firmware, so the hash is taken from the stage-1 image this build produced. - EBLDR_VERIFY_STAGE1 with a board that has no stage-1 linker script is now a configure-time error naming the flag to turn off, rather than a link failure a hundred lines of output later. Verified: the generated file compiles and satisfies the externs (linked against a probe TU declaring them, digest and size match hashlib); a simulated cross-configure shows `stage1_hash.c: eboot_firmware.elf` in the dependency graph and stage1_hash.c.obj in ebldr_stage0's objects. The host build is untouched -- ctest 16/16, pytest 13 passed 1 skipped. Not verified locally: the ARM link itself, for lack of an arm-none-eabi toolchain. The board_stm32f4.c assembly cannot be assembled by host clang.

EoSim/releases/download/v0.1.0/eosim-0.1.0-py3-none-any.whl embeddedos-org/EoSim has no v0.1.0 release, and none of its releases publish a wheel — the newest asset is a promo video. So all 11 simulate jobs, all 3 cross-platform jobs, and the gate that depends on them have failed on master and on every branch since the workflow was written, without a single simulation ever running. ebuild hit exactly this and disabled the steps in its own simulation-test.yml ("EoSim repository not found. Skipping simulation tests."). Same treatment here: the pip install, the eosim invocations and the artifact upload are commented out rather than deleted, so restoring them is a one-line revert once EoSim ships a release. Left alone: .github/workflows/eosim-sanity.yml has the same broken install but runs on a nightly schedule rather than on pull requests, and ebuild left its copy untouched too. Whether to disable a nightly diagnostic is a maintainer call, not something to fold into a build-fix PR.

charset=UTF-8 Content-Transfer-Encoding: 8bit ebuild composes eos and eBoot into one CMake project via add_subdirectory, and CMake requires target names to be globally unique. Two names existed in both repositories: test_crypto eos/tests/CMakeLists.txt:52 eBoot/tests/CMakeLists.txt:10 test_multicore eos/tests/CMakeLists.txt:42 eBoot/tests/CMakeLists.txt:50 So `ebuild integration` — "build all EoS packages together", the only build that checks the two repositories work with each other — was the one build that could not configure: CMake Error at eBoot/tests/CMakeLists.txt:10 (add_executable): add_executable cannot create target "test_crypto" because another target with the same name already exists. The existing target is an executable created in source directory "eos/tests". Each repository configured fine alone, which is why this went unnoticed: the failure only exists in the composition, and nothing was building the composition. All 16 test targets here are prefixed eboot_. The add_test(NAME ...) labels are deliberately left alone — the collision CMake rejects is between targets, not test names — so ctest output is unchanged. A configure-time guard rejects any target in this directory that is not prefixed. Two names collide today; nothing stopped a third, and the next one would fail the same way with the same "green apart, broken together" signature. Verified the guard fires rather than merely existing: add_executable(test_bootctl ...) -> CMake Error: Test target 'test_bootctl' is not namespaced. Name it 'eboot_test_bootctl' so it cannot collide with a target of the same name in eos when ebuild builds both together. Verified: eBoot standalone 16/16 passed, test names unchanged ebuild integration build configure done, was "Configuring incomplete" ecosystem runner, ebuild PASS 38 tests, was FAIL 38 is eos's 22 and eBoot's 16 running in one build for the first time.
