reproducible checks. It is an +upstream self-review, not an independent audit, certification, or guarantee. +`SECURITY.md` defines reporting policy and `THREAT_MODEL.md` defines the +security boundary. ---- +## 5.2.8 scope -## 1. Cryptographic Test Vector Verification +The baseline scope is the source-only CLI and its bundled source codec: -All primitives tested against published reference vectors: +- first-party C and headers under `src/` and `include/`; +- textual architecture-specific source under `jasmin/`, distinguishing + compiler-generated output from separately identified hand-written assembly; +- VaptVupt codec source at release 2.65.3, with provenance and licensing in + `THIRD-PARTY-NOTICES.md`; +- CLI tests, source scanner, build system, CI, and packaging recipes; +- the Python GUI source as a caller of the CLI. -| Primitive | Standard | Vectors | Status | -|-----------|----------|---------|--------| -| SHA-256 | FIPS 180-4 | 3 (empty, "abc", 448-bit) | **PASS** | -| HMAC-SHA256 | RFC 4231 | 2 (TC2: "Jefe", TC3: 20×0xAA) | **PASS** | -| SHA3-256 | FIPS 202 | 2 (empty, "abc") | **PASS** | -| SHAKE-128 | FIPS 202 | 1 (empty, 128-bit output) | **PASS** | -| X25519 | RFC 7748 §5.2 | 2 (both test vectors) | **PASS** | -| ML-KEM-768 | FIPS 203 | 2 (5-trial roundtrip + implicit rejection) | **PASS** | -| XXH64 | xxHash spec | 1 (empty string, seed=0) | **PASS** | -| **Total** | | **13** | **13/13 PASS** | +The baseline is built with `WITH_SDK=0 WITH_PQBOX=0`.

Compiler Warning Audit +Archive inspection must also fail closed at bounded recursion depth, member +count, individual expanded size, and total expanded size so a nested archive or +decompression bomb cannot turn the release scanner into an unbounded resource +consumer.

That manifest does not override a +compiled/executable magic finding. ---- +An artifact is not clean merely because it has a harmless extension. Conversely, +binary image data is not executable code: the documented GUI icon assets are +necessary data and are reviewed separately for purpose, provenance, and license. -## 5.

On +macOS arm64, the strict SHA-NI regression build diagnosed x86-only helper +declarations as unused under `-Werror`.

No +wire-format change — the MAC bytes are identical. + +### What was slow (structural) + +Both `zupt_encrypt_buffer_aad` and `zupt_decrypt_buffer_aad` built the +HMAC input by `malloc`-ing a buffer sized +`aad_extra + nonce + ciphertext + seq` and `memcpy`-ing the **entire +ciphertext** into it, every block, only to feed `zupt_hmac_sha256` once. +With the default 4 MB block size that is a 4 MB malloc plus a 4 MB copy +**per block, per direction**. Separately, `zupt_hmac_sha256` recomputed +the ipad/opad key-prefix SHA-256 compression on every call even though +the per-block `mac_key` never changes. + +### What changed + +- **Incremental HMAC-SHA256 API** (`zupt_hmac_ctx` + + `zupt_hmac_sha256_init/update/final`). `_init` folds the ipad/opad + key-prefix blocks once (one 64-byte compression each); `_update` + streams message segments; `_final` closes the inner+outer hashes. The + context is wiped on `_final` (it holds key-dependent state). +- **The one-shot `zupt_hmac_sha256` is now a thin wrapper** over the + incremental API — single source of truth. The AIT and other + once-per-archive MAC sites are unchanged in behaviour. +- **Both per-block MAC sites stream the segments** (`aad_extra`, then + `nonce || ciphertext` directly from the output package, then + `aad_seq`) through the incremental HMAC. No concat buffer, no + ciphertext copy, no per-block malloc/free. This covers the v1.6 + strict-AAD path and the v1.4/v1.5 legacy-fallback v2 candidate; the + v1 candidate was already a direct one-shot over the package. + +### Why it is wire-compatible (byte-identical MAC) + +RFC 2104 defines `HMAC(K,m) = H((K^opad) || H((K^ipad) || m))`, and +SHA-256's Merkle-Damgard `update()` is associative over the message, so +streaming `m` in segments yields exactly the same tag as hashing one +concatenated buffer. This is not a heuristic — it is pinned by tests: + +- **RFC 4231** HMAC-SHA256 vectors pass (`test_vectors` 14/14). +- New `tests/test_hmac_incremental.c`: one-shot == incremental for + single-segment; streamed 1/2/3-part splits == one-shot across lengths + 0..100000; the exact per-block pattern + `aad || nonce || ciphertext || seq` streamed in four updates == the + concat one-shot; RFC 4231 TC2 known-answer. +- **Byte-exact decryption of archives produced by 3.2.0 and earlier** + (plain and encrypted, both Argon2id and PBKDF2 KDFs) — if the streamed + MAC differed by a single byte, authentication would fail. It does not. + +### Security + +- **Identical authentication semantics.** F-09 byte sweep: **0/1827 + silent accepts**. F-06 1-bit HMAC fuzz: **0/2000**. Constant-time tag + comparisons (byte-OR accumulator / Jasmin `zupt_mac_verify_ct`) are + unchanged. +- **Less secret data on the heap.** The old path copied the full + ciphertext into a second `malloc`'d buffer per block; that buffer is + gone, reducing the lifetime and footprint of sensitive data and the + associated `zupt_secure_wipe` churn. + +### Performance + +Eliminates, per block per direction: one `malloc` of +`~blocksize` bytes, one `memcpy` of the full ciphertext, one +`zupt_secure_wipe` + `free` of that buffer, and (for the key prefix) +two redundant 64-byte SHA-256 compressions. The win scales with block +size and block count and stacks with the 3.2.0 SHA-NI work (fewer +SHA-256 invocations *and* faster ones).

No +wire-format change. + +### Why (measured, not assumed) + +On this project's fixtures, store-mode (codec bypassed) compresses at +**667 MB/s** plain but only **~10 MB/s** with a password. AES-NI is +already active (Jasmin 4-block CTR pipeline), so the cost is the +**Encrypt-then-MAC second pass**: HMAC-SHA256 in scalar C. Scalar +SHA-256 tops out around 150-250 MB/s, which is the wall. PBKDF2 (when +`--kdf pbkdf2` is selected) is HMAC-SHA256 in a tight loop and is hit +even harder. SHA-256 is therefore the correct acceleration target. + +### What was added + +- **`src/zupt_sha256_shani.c`** — the FIPS 180-4 SHA-256 compression + function using Intel SHA Extensions (`SHA256RNDS2`, `SHA256MSG1`, + `SHA256MSG2`), processing multiple 64-byte blocks per call. This is + the canonical Intel/Walton intrinsic sequence (the same one used by + OpenSSL, BoringSSL, and the Linux kernel). Compiled with + `-msha -mssse3 -msse4.1` on x86_64; a no-op translation unit on other + architectures. +- **CPU detection:** `has_shani` added to `zupt_cpu_features_t` + (CPUID.07H:EBX[29]). SHA-NI uses 128-bit `xmm` state from the baseline + x86-64 ABI, so unlike AVX it needs no XCR0/OSXSAVE gate. +- **`zupt_sha256_update()` refactored** to bulk-process full blocks: it + drains any buffered partial, then feeds all full blocks to the + hardware path in one call (`zupt_sha256_transform_shani`) when + `zupt_cpu.has_shani` is set, else the scalar transform in a loop. The + streaming/`final()` semantics are unchanged. + +### Security + +SHA-NI is **constant-time by construction**: it performs no +data-dependent memory accesses or branches, so it has a strictly +stronger side-channel posture than any table- or branch-based software +SHA-256. Since Zupt authenticates with HMAC-SHA256 over +attacker-influenced ciphertext, a constant-time compression function is +the right default wherever the CPU provides it. The scalar fallback is +unchanged and remains the path on non-SHA-NI hardware. + +### Performance + +On SHA-NI hardware (Intel Goldmont+/Ice Lake+, AMD Zen+), the SHA-256 +compression function is **[ESTIMATED] 3-8× faster** than the scalar path +(per the public Intel SHA Extensions throughput figures; this is the +standard speedup OpenSSL/kernel report). **This estimate is not measured +in this release** — the CI/build host used for 3.2.0 has no SHA-NI +(`sha_ni: 0`), so the hardware path cannot be executed here. The number +will be replaced with a measured one once run on SHA-NI silicon. The +`vaptvupt version` command now prints the live hardware-acceleration set +for the running CPU (e.g. `HW accel (this CPU): AES-NI SHA-NI +AVX2(codec)`). + +### Correctness validation (what *was* verified here) + +- **Round constants:** all 64 SHA-NI K-schedule immediates are verified + bit-identical to the scalar `K[]` table, in order — this eliminates + the single most likely class of bug in a hand-written SHA-NI routine. +- **Scalar refactor:** the rewritten `update()`/`sha256_blocks()` passes + the NIST FIPS 180-4 SHA-256 vectors (`test_vectors` 14/14), proving + the new buffering logic is sound on the path this host executes. +- **SHA-NI execution (on SHA-NI hardware only):** the new + `tests/test_sha256_shani.c` checks the SHA-NI path against the NIST + "abc"/empty digests, multi-block == single-block-loop agreement + (64B..64KiB), and streaming-split == one-shot (lengths 0..4096).

The 2.2.4 hypothesis (that the +index region was not MAC'd) was wrong: the index IS MAC'd correctly +on the encrypt side, but the verifier accepted ~6% of tampers in the +HMAC bytes themselves. + +Fix at `src/zupt_crypto.c:438-444` — fold each diff to a single +nonzero-indicator bit before ANDing, constant-time: + +```c +uint64_t nz_v2 = (diff_v2 | (uint64_t)(-(int64_t)diff_v2)) >> 63; /* CT-REQUIRED */ +uint64_t nz_v1 = (diff_v1 | (uint64_t)(-(int64_t)diff_v1)) >> 63; /* CT-REQUIRED */ +uint64_t diff = nz_v2 & nz_v1; +``` + +`(x | -x) >> 63` is the standard branchless "is nonzero" indicator +(0 → 0, anything else → 1) with no data-dependent branches or +secret-dependent memory access. The C-fallback path adopts the same +shape to prevent future divergence. + +**Severity calibration: high but not critical.** The attacker cannot +forge MACs with chosen content — they can only randomly tamper and +get lucky with ≈6% probability per 1-bit flip; multi-bit tampers +decrease exponentially.

But the bug breaks the integrity guarantee SECURITY.md +states ("any modification is detected with overwhelming +probability"), so it must ship as a patch. + +**F-07 — `open_archive()` did not verify `block_type` at +`index_offset`.** The block_type byte is not part of the MAC input, +so flipping it (e.g. from `0x02 INDEX` to `0x03 ENC_HEADER`) did +not cause auth failure; the downstream parser was tolerant. +Severity: low. Fix at `src/zupt_format.c` adds the structural +check immediately after `read_block`. This makes the byte +`OPAQUE` structural-integrity class (tamper detected by parser, not by +MAC). + +**F-02b — RECLASSIFIED.** The 2.2.4 hypothesis that the archive +index region was not MAC'd was incorrect. Exhaustive byte sweep +showed three undetected-tamper positions inside the index region; +one (byte 1620) was F-07, one (byte 1624) is an `OPAQUE`-class +reserved-flag byte that doesn't carry security-significant data, +and one (byte 1713) was F-06 manifesting in the HMAC tail. The +index region IS HMAC-protected; the bug was in the verifier. F-02b +closed without the planned v1.5 format bump. + +**F-08 — Cosmetic archive metadata not covered by any MAC, +deferred to v2.3.0.** Exhaustive byte sweep of a 1771-byte +`--pq-sdk` archive shows 86 remaining undetected-tamper positions +after F-06+F-07.

Packaging must never fetch +`zupt-web` or substitute an asset from another project. + +The `v5.2.2`, `v5.2.3`, `v5.2.4`, `v5.2.5`, `v5.2.6`, and `v5.2.7` tags are +immutable non-promoted candidates. +The v5.2.3 source-policy test assumed LF for a Windows `.bat` file that Git +correctly checks out as CRLF. Exact-tag GitHub Actions run `33431386002` then +recorded 12 successful v5.2.4 jobs, one openSUSE service-harness failure caused +by its working directory, and skipped dependent Windows/macOS jobs. A local +Tumbleweed reproduction confirmed that `refs/tags/v5.2.4` is valid and that +entering the service directory completes the source-service chain. Corrective +working-directory integration was carried by v5.2.5, whose exact-tag GitHub +Actions run `33434986357` completed 13 jobs successfully but failed the native +Windows and macOS jobs. Its v5.2.6 corrections reached exact-tag run +`33442264243`, where 13 jobs succeeded but macOS arm64 failed on unused x86 +SHA-NI test-helper declarations under `-Werror`, and Windows aborted during safe +UTF-8 fixture argv transcoding. Version 5.2.7 corrected those failures, but +exact-tag run `33445470664` ended with 13 successful jobs, a macOS raw-C1 +fixture failure with `EILSEQ`, and a cancelled Windows job after the hosted job +stalled in `make check`; a MinGW/Wine reproduction isolated a non-console +password-prompt hang in `_getch`. Manual 5.2.8 pre-tag run `33452602634` +subsequently passed 14 of 15 jobs, including native macOS and the complete +Windows distribution checks, before an old MSYS `grep` non-BMP pattern failed +in the later smoke. ZUPT's redirected listing was byte-correct; the corrected +gate uses byte-exact, locale-independent checks and requires extraction plus a +full tree diff. The failed run is diagnostic evidence only. +Exact-tag run `33456209269` subsequently passed all 15 jobs at +`ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`, including the pinned local OBS +source-service chain, native +Windows/macOS, and every package gate. Promotion run `33457868306` published +the exact tested 13-file set; the source archive SHA-256 is +`378b9506211545b9594cf0d38ac8955d9b1cac34eb6b379ae0ec26b84edb65f7`. +Corrective packages and release assets use `v5.2.8`; never move or +overwrite an earlier tag or checksum, and never transfer prior evidence +automatically. Version 5.2.8 corrects those native test boundaries, hardens +three path-race boundaries, and adds the SDK regression to release/hosted Linux +gates. The archive format, cryptography, codec, and SDK ABI remain unchanged. + +## Source-only boundary + +Git, `git archive`, and the upstream source tarball contain source code, +textual assembly, documentation, packaging metadata, and necessary data files. +They do not contain compiled objects or executables, shared or static libraries, +or DEB/RPM/AppImage packages. + +The default build is deliberately independent of the optional SDK and PQBOX +libraries: + +```sh +make clean +make -j"$(getconf _NPROCESSORS_ONLN 2>/dev/null || printf 1)" \ + WITH_SDK=0 WITH_PQBOX=0 +make WITH_SDK=0 WITH_PQBOX=0 check +``` + +`WITH_SDK=1` and `WITH_PQBOX=1` use separately installed system development +libraries. They never load a library committed under `vendor/`, never download +a dependency during build or test, and fail explicitly when their development +metadata is unavailable. Distribution builds should keep both options at `0` +unless the corresponding source-built system packages are declared as build +requirements. + +Audit the current tree or a generated archive with: + +```sh +scripts/check-source-only.sh +scripts/check-source-only.sh --archive /path/to/zupt-5.2.8.tar.gz +``` + +The scanner reports paths, not file contents, and exits nonzero on a violation. + +## Reproducible source archive + +`make dist` verifies committed `HEAD` and exports its tree object, normalizes +member order, timestamps, owner/group metadata, and gzip metadata, and audits +the result before moving it to its destination. Exporting the tree rather than +the commit omits Git's commit-ID PAX header: + +```sh +make DIST_TARBALL=/tmp/zupt-5.2.8.tar.gz dist +sha256sum /tmp/zupt-5.2.8.tar.gz +``` + +The canonical release uses the tracked `.source-date-epoch`; an explicit +`SOURCE_DATE_EPOCH` override intentionally creates a different archive. With +identical committed input and epoch, repeated exports must have the same +SHA-256 digest. Do not generate a release tarball from uncommitted working-tree +files. + +The AUR, Homebrew, and Guix recipes pin the checksum of this tarball. They are +marked `export-ignore` in `.gitattributes` so their own checksum fields do not +make the archive self-referential. A commit changing only those ignored recipes +therefore leaves the fixed-epoch archive byte-identical. The recipes remain +versioned in Git and must be updated after the final source archive checksum is +known. + +Do not commit the generated tarball or checksum file. Host them as immutable +release assets after the release tag is published. + +## Staged installation + +Packagers should preserve distribution flags and install into a package root: + +```sh +make -j"${JOBS:-1}" WITH_SDK=0 WITH_PQBOX=0 \ + CPPFLAGS="$CPPFLAGS" CFLAGS="$CFLAGS" \ + LDFLAGS="$LDFLAGS" LDLIBS="$LDLIBS" +make WITH_SDK=0 WITH_PQBOX=0 check +make DESTDIR="$pkgroot" PREFIX=/usr \ + WITH_SDK=0 WITH_PQBOX=0 INSTALL_LEGACY_ALIAS=0 install +``` + +`INSTALL_LEGACY_ALIAS=0` installs only `zupt`. The `vaptvupt` +command can be requested explicitly with `INSTALL_LEGACY_ALIAS=1`, but it is +not installed by default and is not part of the openSUSE main package. This +keeps the canonical package surface limited to ZUPT and `zupt`. + +The Makefile accepts the usual `BINDIR`, `LIBDIR`, `INCLUDEDIR`, `MANDIR`, and +completion-directory overrides. It does not strip package builds or add a +private-library RPATH. + +## Packaging material + +| Target | Maintained path | Intended output | +|---|---|---| +| openSUSE / OBS | `packaging/opensuse/` | source and binary RPM through OBS | +| Debian / Ubuntu | `packaging/debian/`, `packaging/build-deb.sh` | Debian metadata and binary DEB after the target gate | +| RPM release artifact | `packaging/opensuse/zupt.spec`, `packaging/build-rpm.sh` | source and binary RPM after the target gate | +| GUI DEB | `packaging/build-gui-deb.sh` | `zupt-gui_5.2.8_all.deb` after payload/dependency and installed integration gates | +| GUI RPM | `packaging/build-gui-rpm.sh` | `zupt-gui-5.2.8-1.noarch.rpm` and matching `.src.rpm` after package and installed integration gates | +| Linux CLI archive | `.github/workflows/ci.yml` | `zupt-5.2.8-linux-x86_64.tar.xz` with notices after dependency, member, and extracted functional gates | +| Portable GUI source | `packaging/portable/`, `.github/workflows/ci.yml` | `zupt-gui-5.2.8-portable.zip` after source scan, member allowlist, and extracted off-screen integration gate | +| Fedora / RPM-based systems | `packaging/rpm/zupt.spec` | downstream RPM starting point | +| AppImage helper | `packaging/build-appimage.sh` | downstream-only helper; no 5.2.8 AppImage is promoted | +| Windows | `.github/workflows/cross-platform.yml` | native ZIP (executable plus notices) after the required native gate | +| macOS | `packaging/build-dmg.sh` | native-architecture DMG after the native gate | +| Arch Linux | `packaging/aur/PKGBUILD` | AUR package recipe | +| Homebrew | `packaging/homebrew/zupt.rb` | formula-built package | +| Guix | `packaging/guix/zupt.scm` | Guix package definition | +| Nix | `packaging/nix/flake.nix` | flake-built package | + +These files are upstream starting points. Use each distribution's isolated +builder and current policy checks; do not claim support based only on parsing a +recipe. + +### openSUSE / OBS + +The authoritative instructions, tested matrix, and outstanding gates are in +`packaging/opensuse/README.md`. The normal local flow is: + +```sh +cd packaging/opensuse +xmllint --noout _service +osc service manualrun +rpmspec -P zupt.spec >/dev/null +osc build openSUSE_Tumbleweed x86_64 zupt.spec +``` + +Run `rpmlint` on all produced RPMs and install the binary RPM in a disposable +environment for `--version`, `--help`, and archive round-trip tests. Presence of +the OBS files upstream does not mean the package has been submitted or accepted +by openSUSE Factory. + +### Debian and RPM release artifacts + +The release helper scripts build from this source tree, stage into temporary +directories, run their format and installed-binary checks, and place only their +final outputs in an explicitly selected directory. Run them from an exact +checkout of the immutable tag inside a clean target container, chroot, or VM: + +```sh +release_dir=$(mktemp -d) + +# Native Debian/Ubuntu binary package +DIST_DIR="$release_dir" RUN_CHECKS=1 packaging/build-deb.sh + +# Source and binary RPM using the openSUSE spec +DIST_DIR="$release_dir" packaging/build-rpm.sh + +# Architecture-independent GUI DEB and noarch/source GUI RPM +DIST_DIR="$release_dir" packaging/build-gui-deb.sh +DIST_DIR="$release_dir" packaging/build-gui-rpm.sh +``` + +`packaging/build-deb.sh` creates a native binary DEB; it does not claim to +create a Debian source package. The files in `packaging/debian/` are Debian +source-package metadata and must be staged as the source package's top-level +`debian/` directory before using `dpkg-buildpackage`. Running +`dpkg-buildpackage` directly at the ZUPT repository root is not the +documented release-artifact path. + +`packaging/build-rpm.sh` creates its audited Source0 archive, builds both the +binary RPM and source RPM, inspects the installed payload, and copies both +outputs to `DIST_DIR`. The separate `packaging/rpm/zupt.spec` is a +Fedora-family downstream starting point; build and lint it only after staging +Source0 in a normal RPM build tree. + +Run the target's metadata and lint tools in addition to the script gates. A +package built for one distribution release or architecture is not evidence for +another. + +The GUI helpers package Python/Qt source rather than compiled application code. +They validate exact version, payload, dependency, ownership and legacy-alias +expectations, then test the installed launcher off-screen against the matching +`zupt` CLI. A successful GUI DEB gate does not imply an RPM gate, or vice versa. + +### Portable and native release artifacts + +The Linux x86_64 gate packages the tested `zupt` executable as +`zupt-5.2.8-linux-x86_64.tar.xz` beside README, changelog, security guidance, +and every applicable public license and notice. Its dynamic-library allowlist, +archive member allowlist, and extracted CLI functional suite must pass. + +The `zupt-gui-5.2.8-portable.zip` artifact is source-only: it contains the GUI +Python source, shell/macOS/Windows launchers, icons, provenance, changelog, and +licenses, but no Python, Qt, CLI, or compiled runtime. The gate scans both the +assembled and extracted trees, verifies an exact safe member allowlist, and +runs the extracted launcher off-screen against the tested CLI. + +AppImage creation is deliberately offline and is not a 5.2.8 release gate. +Supply a locally verified `appimagetool`, type-2 runtime, and the complete +license/source-relink compliance notice for those exact runtime bytes; the +helper never downloads any input: + +```sh +DIST_DIR="$release_dir" RUN_CHECKS=1 \ +APPIMAGETOOL=/verified/path/appimagetool \ +APPIMAGE_RUNTIME_FILE=/verified/path/runtime-x86_64 \ +APPIMAGE_RUNTIME_COMPLIANCE_FILE=/verified/path/runtime-compliance.txt \ + packaging/build-appimage.sh +``` + +The runtime inspected while preparing 5.2.2 omitted a linked component from +its notice and did not provide the complete LGPL source/relink handoff required +by this release policy. No AppImage produced by this helper is promoted by the +upstream 5.2.8 workflow. AppDir and Flatpak bundles and GUI platform installers +are also excluded. Bare Linux and Windows executables are not promoted; their +CLI programs appear only inside notice-bearing archives. The Windows ZIP and +macOS DMG remain CLI-only. + +Run `packaging/build-dmg.sh` only on a native macOS host. It records the host +architecture in the filename and tests the binary before and after packaging: + +```sh +DIST_DIR="$release_dir" RUN_CHECKS=1 packaging/build-dmg.sh +``` + +The Windows ZIP (including its executable and notices) must be built and tested +by the Windows job in `.github/workflows/cross-platform.yml`; it is not a +cross-compiled release claim from a Linux build. No Wine result is retained as +5.2.8 release evidence. Extended-length/device namespace paths, raw UNC output +roots, and mapped/network-drive output are not supported in 5.2.8. Publish the +exact architecture recorded by the native job. +These helpers create binary distribution artifacts for the release page, not +content to be committed to Git or included in the source archive. + +### AUR, Homebrew, Guix, and Nix + +After calculating the final reproducible source archive, but before creating or +publishing the immutable tag, update each recipe to version 5.2.8 and to the +exact digest or content hash expected by its package manager. These recipe +directories are excluded from the source archive, so this does not create a +checksum cycle. Commit the pinned recipes in the tagged tree, then build and +test with each package manager before publishing its recipe. Keep build inputs +offline-capable: the check phase must not fetch source or dependencies +dynamically. + +## Release-page artifacts + +The source-only policy applies to Git and upstream source archives. A release +page may also carry CLI/GUI DEB and RPM artifacts, the notice-bearing Linux CLI +tar.xz, source-only portable GUI ZIP, CLI Windows ZIP, or CLI macOS DMG when +each is built from the tagged source in its target environment and passes its +format-specific tests. These are separate outputs, never inputs to a source +build. + +For every published artifact: + +1. start from the immutable `v5.2.8` tag; +2. keep `WITH_SDK=0 WITH_PQBOX=0` unless system dependencies are declared; +3. record the exact OS, distribution release, architecture, and toolchain; +4. run format validation plus installed `--version`, `--help`, and archive + round-trip tests; +5. publish a SHA-256 checksum; +6. scan the source inputs and ensure no credential or build path is embedded; +7. label an unbuilt or untested target `SKIP`, never `PASS`. + +Do not infer multi-architecture compatibility from portable source.

A local Tumbleweed +reproduction confirmed both the explicit tag ref and the corrected +working-directory contract. This is release/test integration only; the product, +archive format, cryptography, codec, and SDK ABI are unchanged. The immutable +`v5.2.5` candidate was likewise not promoted: exact-tag GitHub Actions run +`33434986357` recorded 13 successful jobs and failed native Windows/macOS jobs. +The immutable `v5.2.6` candidate was not promoted after run `33442264243` +recorded 13 successful jobs and two native failures: unused x86 SHA-NI helper +declarations on macOS arm64 under `-Werror`, and early Windows abortion while +argv-transcoding a safe UTF-8 fixture. Version 5.2.7 corrected those boundaries +but was not promoted after exact-tag run `33445470664`: 13 jobs succeeded, +macOS failed because its filesystem rejected the raw-C1 filename fixture with +`EILSEQ`, and Windows was cancelled after the hosted job stalled in `make +check`; a MinGW/Wine reproduction isolated the cause to the non-console +password-prompt test entering `_getch`. Version 5.2.8 makes both +fixtures portable, hardens the three CodeQL High path-race boundaries described +in the security documents, and adds `sdk-test` to release and hosted Linux +gates. Exact-tag run `33456209269` passed all 15 jobs, and promotion run +`33457868306` published the exact tested set. Do not treat any prior candidate's +artifacts or evidence as 5.2.8 packages or validation. -Put all the downloaded files in the same folder, then: +The published 5.2.8 package set is exactly these 13 gated assets: -```bash -sudo bash install-zupt-gui.sh -``` - -This script auto-detects your distribution and installs everything in -the right order.

By contrast, +our General Public Licenses are intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + Developers that use our General Public Licenses protect your rights +with two steps: (1) assert copyright on the software, and (2) offer +you this License which gives you legal permission to copy, distribute +and/or modify the software. + + A secondary benefit of defending all users' freedom is that +improvements made in alternate versions of the program, if they +receive widespread use, become available for other developers to +incorporate. Many developers of free software are heartened and +encouraged by the resulting cooperation. However, in the case of +software used on network servers, this result may fail to come about. +The GNU General Public License permits making a modified version and +letting the public access it on a server without ever releasing its +source code to the public. + + The GNU Affero General Public License is designed specifically to +ensure that, in such cases, the modified source code becomes available +to the community. It requires the operator of a network server to +provide the source code of the modified version running there to the +users of that server. Therefore, public use of a modified version, on +a publicly accessible server, gives the public access to the source +code of the modified version. + + An older license, called the Affero General Public License and +published by Affero, was designed to accomplish similar goals. This is +a different license, not a version of the Affero GPL, but Affero has +released a new version of the Affero GPL which permits relicensing under +this license. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU Affero General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Remote Network Interaction; Use with the GNU General Public License. + + Notwithstanding any other provision of this License, if you modify the +Program, your modified version must prominently offer all users +interacting with it remotely through a computer network (if your version +supports such interaction) an opportunity to receive the Corresponding +Source of your version by providing access to the Corresponding Source +from a network server at no charge, through some standard or customary +means of facilitating copying of software. This Corresponding Source +shall include the Corresponding Source for any work covered by version 3 +of the GNU General Public License that is incorporated pursuant to the +following paragraph. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the work with which it is combined will remain governed by version +3 of the GNU General Public License. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU Affero General Public License from time to time. Such new versions +will be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU Affero General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU Affero General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU Affero General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU Affero General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU Affero General Public License for more details. + + You should have received a copy of the GNU Affero General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If your software can interact with users remotely through a computer +network, you should also make sure that it provides a way for users to +get its source. For example, if your program is a web application, its +interface could display a "Source" link that leads users to an archive +of the code. There are many ways you could offer source, and different +solutions will be better for different programs; see section 13 for the +specific requirements. + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU AGPL, see +. diff --git a/LICENSE-BSD-2-Clause b/LICENSE-BSD-2-Clause new file mode 100644 index 0000000..e4c5da7 --- /dev/null +++ b/LICENSE-BSD-2-Clause @@ -0,0 +1,26 @@ +xxHash Library +Copyright (c) 2012-2021 Yann Collet +All rights reserved. + +BSD 2-Clause License (https://www.opensource.org/licenses/bsd-license.php) + +Redistribution and use in source and binary forms, with or without modification, +are permitted provided that the following conditions are met: + +* Redistributions of source code must retain the above copyright notice, this + list of conditions and the following disclaimer. + +* Redistributions in binary form must reproduce the above copyright notice, this + list of conditions and the following disclaimer in the documentation and/or + other materials provided with the distribution. + +THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS "AS IS" AND +ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED +WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE +DISCLAIMED.

By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. But first, please read +. diff --git a/Makefile b/Makefile index fa6bdf6..5b6ec4e 100644 --- a/Makefile +++ b/Makefile @@ -1,47 +1,120 @@ -# Zupt — backup compression with hybrid post-quantum encryption +# SPDX-License-Identifier: AGPL-3.0-or-later +# ZUPT — backup compression with hybrid post-quantum encryption # Build system.

Encrypt always.** +Version 5.2.8 closes three CodeQL High path-race findings: SDK key copies now +publish atomically through an already-open private object, POSIX disk restore +classifies and retains the descriptor it actually opened, and benchmark cleanup +traverses only pinned descriptors or handles without following links or Windows +reparse points. It also makes the raw-C1 scanner fixture explicitly skip a +filesystem that rejects creation with `EILSEQ`, normalizes Bash 3.2 signed-byte +diagnostics, and brings `sdk-test` into the +release and hosted Linux gates. Windows password prompts now reject redirected +input before entering `_getch` and treat console EOF as an error; its key-file +regression validates the protected current-user-only DACL rather than an MSYS +POSIX-mode projection. The C/C++ default-branch scan run `33452563116` of +commit `7a8e5c5` completed successfully after the follow-up changed the new SDK +regression to no-follow descriptors plus `fstat` and descriptor reads. Alerts +#5 through #10 are fixed, and the authenticated code-scanning API reported zero +open alerts. Final release-commit CodeQL run `33456049125` also completed +successfully, with the API still reporting zero open alerts.

That run includes the pinned +local OBS source-service chain, reproducible source checks, GCC/Clang, analyzers, +sanitizers, DEB/RPM/SRPM and portable-package gates, the native Windows ZIP +round trip, and the mounted macOS arm64 DMG test. Corrected promotion run +`33457868306` validated and published exactly 13 assets.

An optional `vaptvupt` command alias may be provided +for scripts written against versions 3.0.0 through 5.2.1. -- **Hardware-adaptive codec** — auto-detects AVX2/NEON at runtime and selects the best codec: VaptVupt (LZ77 + tANS + SIMD decode) on capable hardware, Zupt-LZHP on everything else. Override with `--vv` or `--lzhp`. -- **Post-quantum encryption** — `--pq` mode uses ML-KEM-768 + X25519 hybrid KEM (same approach as Signal and iMessage). Protects against "harvest now, decrypt later" quantum attacks. -- **AES-NI hardware acceleration** — AES-256-CTR via Jasmin-verified assembly with 4-block interleaved pipeline. Safe AVX detection with OSXSAVE/XCR0 validation — no SIGILL on any CPU. Falls back to C table-based AES on unsupported hardware. -- **Multi-threaded** — Compression and decompression both parallelized. `-t 0` auto-detects cores. -- **Full-disk backup** — `zupt disk backup` clones entire disks or partitions in one command. Sparse block detection skips zero regions, real-time progress bar, all encryption modes supported. Restore with byte-for-byte verification via per-block XXH64 checksums. -- **Encrypted backups in one command** — `zupt compress -p changeme backup.zupt ~/data/` — AES-256 + HMAC-SHA256, file names hidden. -- **Per-block integrity** — XXH64 checksum + HMAC-SHA256 per block. Wrong password rejected instantly. -- **Formally verified crypto** — 5 Jasmin assembly functions with constant-time proofs. 19 ACSL-annotated functions for Frama-C memory safety analysis. -- **Multi-architecture** — builds on x86_64, aarch64, armhf, ppc64le, s390x, riscv64. Jasmin CT crypto on x86_64, C fallback everywhere else. Any archive decompresses on any architecture. -- **Zero dependencies** — ML-KEM, X25519, Keccak, SHA-256, AES-256, HMAC, PBKDF2, VaptVupt codec — all pure C11. Builds with `gcc` or `cl` alone. +## Corrective changes in 5.2.8 ---- +SDK key saves use atomic descriptor/handle-backed publication and preserve the +requested private/public modes without reopening the destination. Disk restore +opens a POSIX target once before its type, identity, and device-capacity +decisions, and benchmark cleanup is descriptor-relative on POSIX and +handle/reparse-point aware on Windows. The live-workspace symlink regression, +SDK link-target/mode regression, static path-race guards, portable raw-C1 +fixture with Bash 3.2 unsigned-byte normalization, native redirected-prompt +and protected-DACL regressions, byte-exact BMP/non-BMP Windows list and extract +checks, and `sdk-test` CI step cover these boundaries. All current release +paths moved to 5.2.8 and received fresh exact-tag hosted CI, package, +native-platform, source-only, checksum, OBS, and promotion evidence in runs +`33456209269` and `33457868306`. -## Quick Start +## Corrective changes introduced in 5.2.7 -### Fast installation -``` -curl -fsSL https://short.securityops.co/zupt | bash -``` +The SHA-NI regression keeps x86-only helper declarations out of unsupported +arm64 builds, and the safe UTF-8 Windows fixture crosses the argv boundary in a +byte-stable representation. Those test-harness changes did not alter the +archive format, cryptography, codec, or SDK ABI. Exact-tag run `33445470664` +subsequently exposed the separate macOS raw-C1/EILSEQ fixture failure; Windows +was cancelled after the hosted job stalled in `make check`; MinGW/Wine then +isolated the stall to a non-console password prompt entering `_getch`. The run recorded 13 successful jobs, one +failure, and one cancellation; v5.2.7 remained unpromoted. -### Build & Install -``` -git clone https://git.securityops.co/cristiancmoises/zupt.git && \ -cd zupt && \ -make && \ +## Corrective changes introduced in 5.2.6 + +Darwin and NetBSD select the portable compiler-resistant secure-wipe fallback; +scanner option/path arrays are guarded for Bash 3.2; and hostile Windows path +fixtures use explicit bytes and reject dangerous raw diagnostic fragments. +Those corrections changed release/test integration only. The resulting v5.2.6 +candidate was not promoted because its next exact-tag run exposed the distinct +arm64 SHA-NI helper and safe UTF-8 Windows argv failures described above. + +## Corrective changes introduced in 5.2.5 + +The exact-tag openSUSE gate executes its standalone service chain from the +directory containing `_service`. A local Tumbleweed reproduction confirmed +that `refs/tags/v5.2.4` resolves correctly and that entering the service +directory completes `obs_scm`, `tar`, and `recompress`. The immutable v5.2.4 +candidate recorded 12 successful jobs in run `33431386002`; its openSUSE job +failed before the correction and dependent Windows/macOS jobs were skipped. + +## Corrective changes introduced in 5.2.4 + +The release gate now validates the required CRLF checkout form without treating +it as source drift. That candidate required fresh exact-tag CI, package, +native-platform, source-only, and checksum evidence before promotion.

Falls back to scalar on unsupported hardware. -- **Rep-match** — checks 3 recent offsets before hash probe (O(1) vs O(chain_depth)), hits ~30% of matches. Saves 10–15 bits per repeated offset. -- **Order-1 context model** — captures byte-pair correlations in structured data (JSON, CSV, logs) -- **Cost-aware lazy parser** (Sprint 120) — the breakthrough that put EXTREME ahead of zstd-3 in aggregate ratio -- **Adaptive window** — trial-compresses at wlog=16 vs wlog=20, picks larger window only if ≥3% improvement -- **`format_v2` (T-tag, min_match=3)** — 4–7% better binary ratio; transparent to v2.33.0+ decoders -- **Memory hygiene** (Sprint 118) — encoder working buffers scrubbed via `vv_secure_zero` before `free()` -- **~6,500 lines** of pure C11 — auditable, portable, no external dependencies - ---- - -## Post-Quantum Encryption - -`--pq` mode uses hybrid ML-KEM-768 + X25519 key encapsulation per NIST FIPS 203. - -``` -Public key → ML-KEM-768 Encaps + X25519 ECDH → hybrid shared secret - → SHA3-512(ss ‖ transcript) → enc_key[32] + mac_key[32] - → AES-256-CTR + HMAC-SHA256 per block -``` - -**Security model:** Secure if EITHER ML-KEM-768 (post-quantum) OR X25519 (classical) is secure. - -**Password mode (`-p`) is NOT quantum-safe.** Use `--pq` for long-term protection. - ---- - -## Full-Disk Backup - -Clone entire disks, partitions, or raw images with compression and encryption in one command. - -### Quick start -```bash -# Clone a partition (requires read access) -sudo zupt disk backup backup.zupt /dev/sda1 - -# Clone with post-quantum encryption (strongest) -zupt keygen -o mykey.key -zupt keygen --pub -o pub.key -k mykey.key -sudo zupt disk backup --pq pub.key backup.zupt /dev/nvme0n1p2 - -# Clone with password encryption -sudo zupt disk backup -p backup.zupt /dev/sda1 - -# Maximum compression (level 9, extreme mode) -sudo zupt disk backup -l 9 backup.zupt /dev/sda1 - -# Restore to a device or file -sudo zupt disk restore backup.zupt /dev/sda1 -sudo zupt disk restore --pq mykey.key backup.zupt /dev/sda1 -``` - -### How it works - -``` -Source device → Read 4MB blocks → Sparse detection → Compress → Encrypt → Write .zupt - │ │ │ - │ │ └─ AES-256-CTR + HMAC-SHA256 - │ └─ VaptVupt/LZHP (auto-selected) - └─ Zero blocks stored as STORE (near-zero overhead) -``` - -Zupt reads the source device sequentially in 4MB chunks. Each block is checked for all-zero content (sparse detection uses 8-byte-wide comparison). Zero blocks are stored with codec `STORE` — effectively just the block header with no payload, saving both compression CPU time and archive space. Non-zero blocks are compressed with the selected codec and optionally encrypted. Per-block XXH64 checksums ensure byte-for-byte integrity on restore. - -### Best practices - -**Encryption hierarchy (strongest → fastest):** - -| Mode | Command | Security Level | Speed Impact | -|------|---------|---------------|-------------| -| PQ Hybrid | `--pq pub.key` | Quantum-resistant + classical | ~5% overhead | -| Password | `-p` | AES-256, PBKDF2 600K iter | ~3% overhead | -| None | (default) | Integrity only (XXH64) | Fastest | - -**Compression levels for disks:** - -| Level | Mode | Best for | Typical ratio | -|-------|------|----------|--------------| -| `-l 1` to `-l 3` | Ultra-Fast | Live systems, NVMe (speed priority) | 1.5–2.5:1 | -| `-l 4` to `-l 7` | Balanced (default) | General partitions, ext4/NTFS | 2–5:1 | -| `-l 8` to `-l 9` | Extreme | Cold storage, archival backups | 3–10:1 | - -**Operational guidance:** - -- **Unmount before backup** for filesystem consistency. For live systems, use LVM snapshots or filesystem freeze: `fsfreeze -f /mnt/data && zupt disk backup ... && fsfreeze -u /mnt/data`. -- **Block devices require root** on Linux. Regular files (disk images, `.img`, `.raw`) do not. -- **Sparse-heavy disks** (freshly formatted, VMs with thin provisioning) compress extremely well — the sparse detector skips zero blocks at memory-copy speed with no compression overhead. -- **Verify after backup** with `zupt test archive.zupt` — checks every block's XXH64 checksum without extracting. -- **PQ encryption for long-term** — disk backups stored for years should use `--pq` to resist future quantum attacks. Generate one keypair, store the private key offline, distribute the public key. -- **Restore is non-destructive on files** — writing to a regular file creates/overwrites it. Writing to a block device overwrites the raw device. Double-check the target path before restoring to a device. - -### Comparison with other tools - -| Feature | Zupt disk | dd + gzip | Clonezilla | partclone | -|---------|-----------|-----------|------------|-----------| -| Compression | VaptVupt/LZHP (adaptive) | gzip (fixed) | Multiple | Multiple | -| Encryption | AES-256 + PQ hybrid | None (pipe to gpg) | None | None | -| Sparse detection | Automatic | None | Filesystem-aware | Filesystem-aware | -| Per-block integrity | XXH64 per block | None | None | CRC32 | -| Single binary | ✓ (zero deps) | 2+ tools | ISO boot | Multiple | -| Post-quantum | ML-KEM-768 | — | — | — | -| Cross-platform | 6 architectures | ✓ | x86 only | Linux only | - ---- - -## Multi-Architecture Support - -Zupt builds and runs on all major architectures.

Prefer `--password-prompt`, `--pass-file` with restrictive +permissions, or `--pass-fd` with a descriptor inherited from a trusted caller. +The file/descriptor forms read one line, remove LF and an optional preceding CR, +and reject empty, NUL-containing, or overlong input. ZUPT does not enforce +password-file ownership or mode; the caller remains responsible for creating, +protecting, and deleting that file. The descriptor form duplicates the supplied +descriptor and does not close the caller's original descriptor. +The duplicate shares the same underlying stream and offset, and buffered input +may consume beyond the password line. Pass a descriptor dedicated to this one +password read; do not reuse it as a multi-record protocol channel. -The following attack vectors are now explicitly defended against: +On POSIX terminals, the explicit prompt saves terminal state and installs +signal-aware cleanup so a handled interruption restores echo and other changed +settings before termination. This behavior is covered by a PTY regression and +passed in the full local Linux gate for commit `ff99770`. +On Windows, the prompt requires a real console input handle before entering +`_getch`; redirected input and console EOF fail instead of blocking a native +release gate. -- **Malicious archive with path-traversal entries** (Zip Slip 2018 pattern): - rejected by `zupt_path_is_safe()` — blocks `..`, absolute paths, Windows - drive letters, UNC paths, embedded NULs. -- **Symlink at extract target** (TOCTOU pre-extraction): refused by - `zupt_safe_fopen_output()` using `O_NOFOLLOW` on POSIX.

An attacker - who swaps two valid encrypted blocks between positions in the archive - produces blocks whose AAD no longer matches their position; both MAC - candidates (v2 with AAD, v1 legacy fallback) reject the swapped block. - Empty/partial output files are `unlink()`'d on auth failure. - Limitation: dedup mode uses sentinel seq=0 (refs can't derive source - AAD); plaintext XXH64 still provides per-block integrity. +## Native key files -### Path traversal — operational guidance +Native private keys use no-replace creation: POSIX files are mode `0600` and +Windows files receive a current-user-only DACL. An existing destination is +never truncated. If write, flush/fsync, or close fails, ZUPT deliberately leaves +the exclusively created incomplete or durability-uncertain file at that path +for the user to inspect and remove. It does not unlink by pathname after close, +which avoids deleting a replacement installed during a race. Public keys may be +shared deliberately and are not treated as secret. ZKEY and ZPQK readers +validate the checksum, format version, flags, reserved bytes, exact encoded +size, and public/private role before using any key material. A truncated, +extended, structurally invalid, or role-confused key is rejected rather than +partially accepted. -Even with the in-binary defenses, operators extracting untrusted archives -should: +### Optional integrations -1. Extract into a dedicated empty directory (not `~/Downloads` or `/tmp`). -2. Audit symlinks in the target directory before extraction. -3. Run extraction as a low-privilege user, never root. -4. On Windows, pre-create the target directory with restrictive ACLs - (the `O_NOFOLLOW` defense is POSIX-only). +The 5.2.8 default is `WITH_SDK=0 WITH_PQBOX=0`: -These are belt-and-suspenders — the in-binary defenses are the primary -control, but defense in depth is good practice. +- `WITH_SDK=1` enables libvuptsdk-backed features, including the SDK PQ mode + and Argon2id support, using a separately installed system development package. +- `WITH_PQBOX=1` independently enables the libpqvaptvupt sealed-box mode using + its separately installed system development package. -### Out-of-scope (still) +Neither library is committed as a precompiled artifact, and no build path +downloads it. A missing requested dependency is a build error. Security +properties of these optional libraries are outside the source-only CLI audit +unless their exact source package and version are reviewed separately. -- External independent audit (cost-bound, on roadmap) -- Side-channel testing on production hardware (timing leaks) -- Formal verification beyond Jasmin constant-time primitives +The in-repository SDK adapter saves copied keys through the core atomic output +publisher. POSIX permissions are applied to its already-open temporary +descriptor, and publication replaces only the requested directory entry after +copy/close checks succeed. `make sdk-test` exercises private/public modes and +preservation of pre-existing symlink and hardlink targets. This covers the +adapter boundary; it does not certify the separately installed SDK library. +## Cryptographic construction + +Encrypted blocks use a fresh 128-bit nonce, AES-256-CTR, and HMAC-SHA256. The +MAC binds the encrypted payload, canonical block metadata, and the frame's +logical position, and is checked before restored data is accepted. In 5.2.2, +this positional AAD applies to DATA and DEDUP_REF frames. An authenticated +reference is bound to its own position and carries the authenticated source +position needed to verify the referenced DATA frame. + +An archive-integrity trailer (AIT) covers global metadata. The 5.2.2 +`extract`, `list`, `test`, and `disk restore` paths refuse a no-AIT layout by +default, without trusting the archive's unauthenticated `ENCRYPTED` bit to +decide whether that check matters. `--allow-legacy-no-ait` is accepted only by +those commands; it is a recovery-only opt-in for a known, trusted pre-AIT +archive and emits a downgrade warning. Never use it for an archive from +untrusted or attacker-writable storage. `info` only reports unauthenticated +framing and apparent AIT presence; it does not validate the trailer or archive +contents. Plain archives use non-cryptographic checksums and do not provide +protection against an attacker who can rewrite the archive. + +Archive comments are authenticated according to the archive mode, but they are +still untrusted display data. ZUPT renders control bytes safely when showing a +comment and does not emit raw terminal-control sequences. This prevents a valid +or attacker-supplied comment from rewriting terminal output; it does not make a +plain archive cryptographically authentic. + +In new 5.2.2 encrypted+dedup archives, each reference offset is included in +the authenticated reference payload. New encrypted disk archives also +authenticate their index; the index binds the image size, block count, and a +chained XXH64 hash of the complete restored byte stream. The writer +additionally requires an XXH64 and SHA-256/128 match before emitting a dedup +reference, but that SHA-256/128 digest is an in-memory collision guard and is +not stored as an on-disk integrity claim. XXH64 is non-cryptographic: in a +plain archive it +detects accidental corruption but can be recomputed by an attacker. + +The native hybrid derivation implemented by 5.2.2 is: + +```text +ml_ss = ML-KEM-768 shared secret +x25519_ss = X25519 shared secret +hybrid_ikm = ml_ss XOR x25519_ss +archive_key = SHA3-512(hybrid_ikm || ml_ct || ephemeral_pk || + "ZUPT-HYBRID-v1") +``` + +`--pq-only` derives the archive key as +`SHA3-512(ml_ss || ml_ct || "ZUPT-PQ-ONLY-v1")`. + +The native modes are at-rest archive encryption. They do not provide protocol +session forward secrecy: later compromise of the relevant long-term private key +can compromise archives encrypted to it. + +## Constant-time and side-channel scope + +Portable C is the 5.2.8 default. Sensitive comparisons and selections use +branchless helpers, but generated machine-code behavior remains dependent on +the compiler and platform. This is not a formal whole-program constant-time +claim. The C AES implementation uses table lookups and is unsuitable for a +claim of cache-timing resistance on hostile shared hardware. + +Sensitive VaptVupt working buffers are cleared through a compiler-resistant +wipe helper. Platforms with a guaranteed libc `explicit_bzero` use it; macOS +and NetBSD use the portable volatile-write fallback because the supported +deployment targets do not guarantee that symbol. This source-level choice +resists ordinary dead-store elimination but is not a formal claim about every +compiler binary. + +Textual assembly under `jasmin/` can be enabled explicitly with +`WITH_JASMIN=1` on a supported x86_64 compiler target. The directory contains +Jasmin-generated output and separately identified hand-written assembly; all of +it is disabled by default and its inclusion must be confirmed in the exact +binary being assessed. Its availability does not imply formal verification of +the archive parser, compression codec, or the whole program. + +## Security boundary and limitations + +ZUPT is designed for backups created and restored on trusted endpoints. It +does not protect against: + +- malware, keyloggers, memory inspection, or a compromised user account on the + machine handling plaintext or keys; +- disclosure of a password or private key; +- denial of service from arbitrarily large or adversarial input; +- traffic analysis from archive size and visible framing metadata; +- hiding that a file is a ZUPT archive; +- compression-length side channels when attacker-controlled and secret data are + compressed together and an attacker can observe output length; +- network transport attacks, multi-party access control, threshold recovery, or + key rotation; +- every compiler-, microarchitecture-, power-, or speculative-execution side + channel. + +Archive entry paths reject traversal, absolute paths, control characters, +Windows alternate streams/device names, and ambiguous trailing dot/space +components. POSIX extraction resolves each parent relative to a pinned file +descriptor with no-follow semantics after canonicalizing the user-selected +output root once; symlinks below that root remain forbidden. Windows resolves +each parent and temporary +file relative to a directory handle and performs the final no-replace rename by +handle, so a checked path is not looked up again through a mutable junction or +reparse point. An existing destination leaf is never overwritten. + +Decoded bytes first go to a private, exclusively created temporary file. The +final name is published only after the expected decoded size and chained +checksum match and the stream closes successfully; failures remove the +temporary by descriptor/handle. These controls reduce traversal, link, race, +and partial-output risks, but they do not make privileged extraction +appropriate. Extract untrusted archives as a dedicated unprivileged user into +a new empty directory, inspect the result before moving it, and apply OS +sandboxing where available. + +Benchmark workspaces are random private directories. POSIX cleanup opens each +directory component without following links and removes entries relative to +pinned descriptors. Windows retains no-delete-sharing handles for the resolved +ancestors and refuses reparse-point recursion. After emptying a directory, it +reopens that entry relative to the pinned parent, verifies the volume and file +index against the traversal handle, and marks only the identity-checked handle +for deletion. An injected link is removed as a link rather than traversed to +its target. + +Disk restore has a separate destructive-device boundary. It measures and +copies the compacted archive to an exclusively created, auto-deleted private +scratch file, then performs validation and restoration from that same snapshot. +`ZUPT_TMPDIR` is an explicit existing scratch-directory override; an invalid +override fails without fallback. On POSIX, the target is opened once without +truncation or final-symlink following, classified with `fstat`, and—when it is +a supported Linux, macOS, or FreeBSD raw block device—the same descriptor is +retained through capacity checks and writes. Regular files continue through +atomic publication. Unknown device capacity, an undersized device, a +source/destination identity match, or a snapshot failure stops before the +first target write. These checks do not +make raw-device restore non-destructive: verify both operands and keep recovery +media before proceeding. + +These changes address the three 5.2.8 CodeQL High reports: #5 at SDK key +publication, #6 at POSIX disk-target classification/use, and #7 at benchmark +workspace cleanup. The regressions and source review are project evidence, not +an independent certification. Exact-tag run `33456209269` subsequently passed +all 15 jobs at `ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`. + +The C/C++ default-branch analysis of commit `69fc26b` closed #5, #6, and #7, +then opened test-only High #8, #9, and #10 because the new SDK regression used +path-level `stat`/`lstat` before later reads or cleanup. Each individual test +check now uses a no-follow descriptor with `fstat` or descriptor reads; the +static gate rejects reintroduction of path-level metadata checks there. The +subsequent C/C++ default-branch scan run `33452563116` completed successfully at +commit `7a8e5c5`; alerts #5 through #10 are fixed, and the authenticated +code-scanning API reported zero open alerts. +The final release-commit CodeQL run `33456049125` also completed successfully; +the authenticated API again reported zero open alerts, with #5 through #10 +recorded as fixed rather than dismissed. + +The Windows handle-relative implementation is scoped to normal local Win32 +paths. Win32 extended-length and device-namespace paths, raw UNC output roots, +and mapped/network-drive output are not supported in 5.2.8. Cross-build and +Wine results are not native-Windows evidence; the `windows-latest` package gate +must pass its Unicode round trip before Windows assets are published. Restore +to a normal local directory first and move verified output to network storage +afterward. + +## Historical compatibility and fixes + +These statements are historical release records, not claims that every current +gate was rerun on every platform: + +- In 4.2.0, encrypted deduplication changed from a repeated derived nonce to a + fresh random per-block nonce. Re-encrypt encrypted `--dedup` archives written + by releases through 4.1.0. +- In 5.0.0, native ML-KEM was corrected from round-3 CRYSTALS-Kyber semantics + to FIPS 203 ML-KEM-768. Native `--pq` and `--pq-only` keys and archives from + releases through 4.2.1 are not compatible with the corrected mode. Password + and plain archive paths were not affected by that KEM change. +- Releases predating the archive-integrity trailer may have a structurally + valid no-AIT layout. Such an archive now fails closed unless the caller uses + `--allow-legacy-no-ait` on a supported read command. This option permits + recovery of trusted old media; it is not a general compatibility mode and + does not make unauthenticated header/footer metadata safe. +- Readers since 5.2.2 accept the fixed-width disk index and encrypted-dedup linear + AAD sequence published through 5.2.1 and warns that the legacy index has no + whole-image content hash. Its regression fixture is an actual v5.2.1 + password-encrypted DATA/DATA/REF/DATA disk archive stored as hexadecimal text with + source and hash provenance. The candidate lists, tests, extracts, and restores it + byte-exact; the full local Linux gate passed on commit `ff99770`. This does not + claim that 5.2.1 readers accept the new flag-gated 5.2.2 records or that every + historical encrypted+dedup combination was validated. + +The repository contains NIST/RFC vector tests and an OpenSSL 3.5 ML-KEM +interoperability test. The OpenSSL test can only execute when the environment +provides an ML-KEM-capable OpenSSL; otherwise it must be reported as skipped. + +## Source and release integrity + +Git and upstream source archives contain no compiled executable, object, +shared/static library, or distribution package. Audit them with: + +```sh +scripts/check-source-only.sh +scripts/check-source-only.sh --archive /path/to/zupt-5.2.8.tar.gz +``` + +Nested archive inspection is required to enforce bounded recursion, member +count, per-entry expanded size, and total expanded size, and to fail closed on +limit violations. On commit `ff99770`, the source-only scanner suite passed +39/39, including GNU thin archives, resource-limit cases, and safe diagnostics. + +DEB, binary RPM, SRPM, notice-bearing Linux tar.xz, source-only portable GUI +ZIP, Windows ZIP, and macOS DMG release assets are separate outputs. An +AppImage is not promoted for 5.2.8. A bare Linux or Windows executable is also +excluded; executables are distributed only inside their notice-bearing +archives. Trust an artifact only when its exact format has a recorded build, +content/metadata inspection, extracted or installed smoke test, and applicable +archive round trip. Never treat an unexecuted platform as passing. + +The gated 5.2.8 set is the CLI package/archive set plus the exact GUI DEB, +noarch/source RPM, and source-only portable ZIP documented in the README. The +portable GUI ZIP contains no compiled runtime and is scanned as source before +and after extraction. Other GUI packages, AppImage, AppDir and Flatpak bundles, +and GUI platform installers are excluded. Windows ZIP and macOS DMG artifacts +remain CLI-only. + +## Reproducing project checks + +Start with the baseline source-only build: + +```sh +make clean +make -j"$(getconf _NPROCESSORS_ONLN 2>/dev/null || printf 1)" \ + WITH_SDK=0 WITH_PQBOX=0 V=1 +make WITH_SDK=0 WITH_PQBOX=0 check +make WITH_SDK=0 WITH_PQBOX=0 test-all +make sdk-test +``` + +Where the compiler supports them, run the sanitizer target separately: + +```sh +make test-asan +make test-asan-run +``` + +The first command builds the sanitizer configuration; the second executes its +test suite. Neither substitutes for the normal optimized build and tests. + +The full local Linux `make release-check` passed on the immutable, non-promoted +5.2.2 candidate at `ff99770`. Its recorded evidence includes packaging +`PASS=49 FAIL=0 SKIP=0`, +the 39/39 source-only scanner suite, strict GCC and Clang builds, GCC +`-fanalyzer`, 9/9 static analysis in a tool-enabled run, ASan/UBSan/LSan, and +1,000 mutation-fuzz iterations without a sanitizer-detected crash. An earlier +off-screen GUI smoke run is supporting evidence, not an exact-candidate package +result. + +Post-tag CI integration failures prevented 5.2.2 promotion. Those upstream +self-audit results are not independent certification and do not transfer to +5.2.8. The immutable 5.2.3 candidate was not promoted because its source-policy +test assumed LF for a Windows `.bat` file checked out as CRLF. The immutable +v5.2.4 candidate was not promoted after exact-tag GitHub Actions run +`33431386002`: 12 jobs succeeded, the sole openSUSE job failed in its +standalone source-service harness because it did not enter the service +directory, and dependent Windows and macOS jobs were skipped. A local +Tumbleweed reproduction confirmed that `refs/tags/v5.2.4` is valid and that +`os.chdir(service_dir)` lets `obs_scm`, `tar`, and `recompress` complete with a +source-scanned archive. This was a release/test integration defect, not a +product, archive, cryptographic, codec, or SDK ABI change, and its evidence does +not transfer automatically to 5.2.8. The immutable v5.2.5 candidate was also +not promoted: exact-tag GitHub Actions run `33434986357` recorded 13 successful +jobs and failed native Windows/macOS jobs. Its Windows fixture-byte and macOS +secure-wipe/Bash 3.2 defects were corrected for 5.2.6. A targeted clean-clone +run of the corrected scanner under genuine GNU Bash 3.2.57 passed repository, standalone +tree, standalone archive, and root-plus-tag modes; that local compatibility +result does not transfer to any other gate. Exact-tag v5.2.6 run `33442264243` +then completed 13 jobs successfully but failed native macOS because x86 SHA-NI +test helpers were unused on arm64 under `-Werror`, and failed native Windows +when argv transcoding aborted the safe UTF-8 fixture. Those are test-harness +integration defects, not product, archive, cryptographic, codec, or SDK ABI +changes; v5.2.6 remained unpromoted, so its results did not transfer to the +required 5.2.8 suite. The immutable v5.2.7 candidate was likewise not +promoted: exact-tag run `33445470664` concluded `cancelled` at +`2026-08-31T23:11:19Z`, with 13 successful jobs, one failed macOS job after +raw-C1 fixture creation returned `EILSEQ`, and one cancelled Windows job after +the hosted job stalled in `make check`; a MinGW/Wine reproduction isolated the +cause to a redirected password prompt entering `_getch`. Version 5.2.8 makes +both test boundaries fail or skip without hanging. Manual pre-tag run +`33452602634` subsequently passed 14 of 15 jobs, including the native macOS +DMG and the Windows source audit, build, and full distribution checks. The +remaining Windows smoke failure was an old MSYS `grep` non-BMP pattern boundary +after ZUPT had compressed and verified all inputs; MinGW/Wine confirmed ZUPT's +byte-exact UTF-8 listing. The corrected gate validates Latin-1, BMP, and +non-BMP listing bytes without locale-sensitive matching, then requires +extraction and a full tree diff. The failed run is not exact-candidate +evidence. Exact-tag run `33456209269` then completed 15/15 jobs successfully, +including native Windows/macOS, the pinned local OBS service chain, package +installation/round trips, source-only checks, analyzers, and sanitizers. +Promotion run `33457868306` published the exact 13-file allowlist after +format, metadata, payload, and checksum validation. An unavailable or +unexecuted environment remains `SKIP`, never `PASS`; successful project CI is +still not independent security certification. + +Run target-native static analyzers and package checks as additional evidence. +Do not infer x86_64, aarch64, ppc64le, s390x, riscv64, macOS, Windows, Leap, or +SLE success from these commands unless that exact environment produced a +successful recorded result. + +ZUPT application code is distributed under AGPL-3.0-or-later.

It is +not a certification, a guarantee against every hostile input, or a substitute +for reviewing the exact source and binary used for important data. + +## Intended use + +ZUPT is intended for at-rest backup archives created and restored on +machines controlled by the user. It can be used when the storage provider or +physical medium is not trusted, provided encryption is enabled and credentials +remain secret. + +It is not a network protocol, a full-disk encryption system, a multi-party or +threshold scheme, a password manager, or a way to make an archive's existence +plausibly deniable. + +## Baseline considered here + +The upstream baseline is built from the 5.2.8 source with: + +```sh +make WITH_SDK=0 WITH_PQBOX=0 +``` + +It contains the native password, ML-KEM-768 + X25519 hybrid `--pq`, and +ML-KEM-768-only `--pq-only` modes. It does not load a precompiled library from +the repository and does not download a dependency while building. + +`WITH_SDK=1` and `WITH_PQBOX=1` add separately installed system libraries and +change the assessed code boundary. The SDK and PQBOX integrations must be +reviewed with their exact packaged source and version; success of the baseline +tests is not evidence for them. + +Textual assembly under `jasmin/` is a separate `WITH_JASMIN=1` option for +supported x86_64 compiler targets. The directory contains both generated and +separately identified hand-written assembly. Portable C is the default. +Architecture portability is a source property, not evidence that an unexecuted +architecture passed. + +## Assets + +The assets ZUPT tries to protect are: + +- archived file contents and encrypted index data; +- the integrity and ordering of encrypted archive blocks and current global + metadata covered by the archive integrity trailer; +- private keys, passwords, and derived encryption/MAC keys while held by the + trusted caller; +- safe placement of extracted entries within the requested destination. + +The archive's existence, total byte length, magic, encryption/framing flags, and +some size/structure information are observable. Plain archives provide +corruption detection, not cryptographic protection against an active attacker. + +## Adversaries considered + +The design considers an adversary who can read, copy, truncate, reorder, or +modify stored archive bytes but cannot read the encryption endpoint's memory or +credentials. It also considers accidental corruption and malicious archive +entry paths during extraction. + +The following adversaries are outside the protection boundary: + +- malware, a keylogger, or an administrator on the source or restore endpoint; +- an attacker who obtains the password or matching private key; +- a malicious compiler, kernel, CPU, firmware, or random-number generator; +- an attacker with unrestricted side-channel observation of a shared machine; +- an attacker allowed unbounded CPU, memory, or storage denial of service. + +## Security properties + +### Encrypted archive confidentiality + +Password and native PQ modes encrypt blocks with AES-256-CTR and authenticate +them with HMAC-SHA256. Confidentiality depends on unique nonces, correct +implementations, OS randomness, and credential secrecy. In password mode it +also depends on password entropy; PBKDF2-SHA256 slows but cannot prevent offline +guessing of a weak password. + +Prefer `--password-prompt`, `--pass-file`, or `--pass-fd`. A password supplied +through `-p/--password` can be visible through process inspection or shell +history. A password file is protected only by the caller's filesystem choices; +ZUPT does not validate its ownership or permission bits. A descriptor is +trusted input inherited from the caller. Both non-interactive forms read one +line and reject empty, NUL-containing, or overlong values. The descriptor form +duplicates but shares the underlying stream/offset and may buffer beyond the +line, so callers should provide a descriptor dedicated to that password read. +On POSIX, handled prompt interruptions restore the saved terminal state before +termination; an exact-candidate PTY regression is required before release. +On Windows, a prompt is entered only for a real console input handle; +redirected input and console EOF fail instead of blocking in `_getch`. + +Native private-key generation uses no-replace creation with POSIX mode `0600` +or a Windows current-user-only DACL. A failed write, flush/fsync, or close leaves +the incomplete or durability-uncertain exclusive file for manual review and +removal instead of risking an unlink-after-close race against a replacement +pathname. ZKEY and ZPQK inputs +are accepted only after checksum, version, flags, reserved bytes, exact size, +and public/private role validation. This prevents role confusion and +partial/trailing-key acceptance; it does not protect a key after endpoint or +account compromise. + +When the optional system SDK is enabled, the in-repository adapter copies a key +through the core atomic publisher, applies POSIX mode through the already-open +temporary descriptor, and publishes only after copy/close checks succeed. Its +`sdk-test` regression preserves existing symlink/hardlink targets and verifies +private/public modes. This narrows the adapter boundary; it does not extend the +baseline assessment to the external SDK implementation. + +### Encrypted archive integrity + +Current encrypted archives authenticate ciphertext, canonical block metadata, +and each frame's logical position. DATA and DEDUP_REF frames both receive this +positional AAD. A reference is authenticated at its own position and carries +the authenticated source position needed to verify the referenced DATA frame, +so exchanging otherwise equivalent frames is not accepted. + +Current archives carry an archive-integrity trailer for global metadata. The +`extract`, `list`, `test`, and `disk restore` paths refuse any no-AIT layout by +default without relying on an unauthenticated header flag. +`--allow-legacy-no-ait` is a narrowly scoped, warning-producing recovery option +for those commands when the caller already trusts a pre-AIT archive. Selecting +it for attacker-controlled storage removes the header/footer authentication +assumption and is outside this threat model. `info` is an unauthenticated +framing inspection that reports apparent AIT presence but validates neither the +trailer nor archive contents. These checks do not prevent deletion of the +entire archive, rollback to an older valid archive, or storage-layer replay. + +Archive comments remain untrusted presentation data even when they are +authenticated. Display paths render control bytes without emitting raw terminal +control sequences, limiting terminal-output injection while leaving the stored +and authenticated comment bytes unchanged. + +New 5.2.2 encrypted+dedup archives authenticate each reference offset. New +encrypted disk archives also authenticate an index that binds image size, +block count, and a chained XXH64 hash of the complete restored stream. The +writer's additional SHA-256/128 comparison is only an in-memory collision guard +before deduplication; it is not an on-disk cryptographic hash. XXH64 is not +cryptographic, so a writer who controls a plain archive can recompute it. + +Plain archives use non-cryptographic checksums. A writer who controls a plain +archive can recompute them. + +### Native hybrid post-quantum mode + +The `--pq` mode combines an ML-KEM-768 shared secret and an X25519 shared secret +as implemented in 5.2.2: + +```text +hybrid_ikm = ml_ss XOR x25519_ss +archive_key = SHA3-512(hybrid_ikm || ml_ct || ephemeral_pk || + "ZUPT-HYBRID-v1") +``` + +Its goal is harvest-now/decrypt-later resistance if ML-KEM-768 remains secure, +with X25519 as a classical hedge under the combiner assumptions. This is not +session forward secrecy: compromise of the recipient's long-term private key +can compromise previously captured archives encrypted to it. + +The native `--pq-only` mode removes X25519 and derives a key from ML-KEM-768 +alone. Use it only when a policy specifically excludes the classical component; +it loses the hybrid hedge. + +The in-tree ML-KEM code has project tests, including known-answer vectors and a +conditional OpenSSL 3.5 interoperability test. It has not been independently +audited or formally verified as a whole implementation. + +### Extraction containment + +The reader rejects absolute paths, traversal components, control characters, +ambiguous trailing dot/space components, NTFS alternate-stream syntax, and +reserved Windows device names. POSIX extraction resolves every parent below a +pinned destination descriptor with no-follow operations after canonicalizing +the user-selected root once. Windows extraction +uses handle-relative traversal, rejects reparse-point parents, and publishes the +final name by handle without replacing an existing leaf. A checked path is not +re-resolved through a mutable parent. + +Decoded bytes are first written to a private, exclusively created temporary +file. The final name is published only after the expected decoded size and +chained checksum match and the stream closes successfully; failures remove the +temporary through its descriptor or handle. These controls reduce traversal, +link, race, and partial-output risks, but do not establish that no parser or +filesystem bug can exist. + +Benchmark scratch data lives in a random private directory. Cleanup resolves +POSIX components without following links and deletes relative to pinned +descriptors. On Windows it retains no-delete-sharing ancestor handles, refuses +reparse-point recursion, then reopens each emptied directory relative to its +pinned parent and verifies its filesystem identity before handle-based +deletion. An attacker who inserts a link can cause cleanup failure, but the +cleanup must not traverse to the link target. + +The Windows handle-relative boundary in 5.2.8 covers normal local Win32 paths. +Win32 extended-length and device-namespace paths, raw UNC output roots, and +mapped/network-drive output are not supported. Cross-build and Wine results are +not a substitute for the required native `windows-latest` Unicode package +gate. Restore locally before moving verified output to network storage. + +Disk restore copies the measured compacted archive into one exclusively +created, auto-deleted scratch file. Preflight and restoration consume that same +open snapshot. An explicit `ZUPT_TMPDIR` selects an existing scratch directory; +failure there does not fall back to consuming the mutable source pathname. On +POSIX, the destination is opened once without truncation or final-symlink +following, classified with `fstat`, and the same raw-device descriptor is +retained for supported Linux, macOS, and FreeBSD capacity checks and writes. +Regular-file output retains atomic publication. A raw target is rejected before +writing if its capacity is unknown or smaller than the image. These controls +reduce source exchange, target exchange, and immediate overrun risk but do not +protect against a compromised kernel/device, a wrongly selected sufficiently +large device, power loss, or hardware failure. + +The SDK publication, POSIX disk-target, and benchmark-cleanup changes address +CodeQL High #5, #6, and #7 respectively. Their source review and regressions +alone are project evidence, not independent certification. Exact-tag run +`33456209269` subsequently passed all 15 hosted jobs at +`ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`; final release-commit CodeQL run +`33456049125` completed successfully with zero open alerts. + +For an untrusted archive: + +1. use a new empty destination outside sensitive trees; +2. run as a dedicated unprivileged user, never root; +3. apply a container, sandbox, resource limits, and a storage quota when + available; +4. inspect extracted paths, types, permissions, and content before moving them; +5. never restore a disk image to a device without independently confirming both + source and destination. + +## Non-goals and residual risks + +ZUPT does not claim to provide: + +- resistance to cache, power, EM, acoustic, speculative-execution, or all + compiler-introduced timing side channels; +- bounded resource consumption for every malformed archive; +- confidentiality of archive size or complete framing metadata; +- protection against compression-length oracles when secret and + attacker-controlled data are compressed together; +- rollback detection across multiple valid versions of a backup; +- forward-secure sessions, remote authentication, replay protection, or secure + transport; +- automatic key rotation, recovery, escrow, threshold access, or secure + deletion; +- preservation of every operating-system ACL, ownership attribute, extended + attribute, or special-file semantic; +- safe operation on a compromised host. + +## Credential handling + +- Generate PQ keys on a trusted system using the OS CSPRNG. +- Keep private keys separate from the archive and from release/package inputs. +- Store an offline recovery copy and test recovery before relying on a backup. +- Use a distinct high-entropy credential where compromise isolation matters. +- Re-encrypt under a new credential after suspected disclosure; there is no + in-place key rotation. +- Never include credentials or sensitive archives in bug reports or CI logs. + +## Supply-chain boundary + +Git and upstream source archives are source-only. They must pass +`scripts/check-source-only.sh` and must not contain executable code artifacts, +objects, shared/static libraries, distribution packages, unsafe symlinks, or Git +LFS pointers. + +Nested inspection is itself an untrusted-input boundary. The release scanner +must cap recursion depth, archive members, per-entry expansion, and total +expanded bytes and fail closed when a cap is reached. Commit `ff99770` passed +all 39 source-only scanner cases, including GNU thin archives, scanner-bomb +limits, and safe diagnostic cases. + +DEB, binary RPM, SRPM, notice-bearing Linux tar.xz, source-only portable GUI +ZIP, Windows ZIP, and macOS DMG files can be published separately from the +tagged source. Each artifact extends the trust boundary to its builder, +toolchain, runner image, and packaging scripts. Treat it as validated only when +the exact target has a recorded build, content/package inspection, extracted or +installed smoke test, and applicable archive round trip. An AppImage is not +promoted for 5.2.8; bare Linux and Windows executables are also excluded. + +For 5.2.8, that gated artifact scope covers the CLI files plus the exact GUI +DEB, noarch/source RPM, and source-only portable ZIP named in the README. The +portable ZIP contains no compiled runtime and crosses the release boundary only +after source scans and an exact safe-member check. AppDir and Flatpak bundles +and GUI platform installers remain excluded; Windows ZIP and macOS DMG outputs +remain CLI-only. + +The immutable, non-promoted 5.2.2 candidate at `ff99770` passed the full local +`make release-check`: packaging reported `PASS=49 FAIL=0 SKIP=0`; strict GCC, +strict Clang, GCC `-fanalyzer`, the 9/9 tool-enabled static-analysis run, +ASan/UBSan/LSan, and 1,000 mutation-fuzz iterations passed. Earlier off-screen +GUI smoke evidence is retained separately. Post-tag CI integration failures +prevented 5.2.2 promotion. This upstream self-review is not an independent +certification and is not 5.2.8 evidence. The immutable 5.2.3 candidate was not +promoted because its source-policy test assumed LF for a Windows `.bat` checkout +that correctly used CRLF. The immutable v5.2.4 candidate was not promoted after +exact-tag GitHub Actions run `33431386002`: 12 jobs succeeded, the sole openSUSE +service-harness job failed because its standalone executor did not enter the +service directory, and dependent Windows/macOS jobs were skipped. A local +Tumbleweed reproduction established that the explicit `refs/tags/v5.2.4` +revision works and that `os.chdir(service_dir)` completes the source-service +chain. This narrows the failure to release/test integration; it changes no +product, archive, cryptographic, codec, or SDK ABI boundary and supplies no +automatic 5.2.8 evidence. The immutable v5.2.5 candidate was not promoted after +exact-tag GitHub Actions run `33434986357`: 13 jobs succeeded, but native +Windows and macOS failed on fixture-byte preservation and Darwin/Bash 3.2 +portability respectively. The corresponding 5.2.6 corrections were followed by +exact-tag run `33442264243`: 13 jobs succeeded, while native macOS failed on +x86-only SHA-NI helper declarations unused on arm64 under `-Werror`, and native +Windows aborted during safe UTF-8 fixture argv transcoding. The v5.2.6 tag was +not promoted. Version 5.2.7 corrected those two boundaries, but its exact-tag +run `33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13 +successful jobs, one failed macOS job after raw-C1 filename creation returned +`EILSEQ`, and one cancelled Windows job after the hosted job stalled in `make +check`; a MinGW/Wine reproduction isolated the cause to a redirected password +prompt entering `_getch`. +The corresponding 5.2.8 fixture and prompt corrections alone did not establish +a result. Exact-tag run `33456209269` then passed 15/15 jobs, including +`sdk-test`, native Windows/macOS, the pinned local OBS source-service chain, +and the package/source gates. Promotion run `33457868306` published the exact +13 tested assets. Official authenticated OBS/Factory acceptance, the full +automatic debug-package result, and untested architectures remain unclaimed; +the earlier `debugsource` rpmlint `no-binary` finding remains unresolved and +unsuppressed. + +## Historical compatibility notes + +These are historical facts about earlier releases, retained to support recovery: + +- Releases through 4.1.0 could reuse an AES-CTR nonce in encrypted `--dedup` + archives. Release 4.2.0 changed to fresh random per-block nonces. Re-encrypt + affected older archives. +- Releases through 4.2.1 used round-3 CRYSTALS-Kyber semantics in the native PQ + path. Release 5.0.0 corrected the implementation to FIPS 203 ML-KEM-768, + changing native PQ key/archive compatibility. See `CHANGELOG.md` before + planning cross-version restoration. +- Pre-AIT archive layouts now fail closed by default. The explicit + `--allow-legacy-no-ait` read option is only for recovery from a known, trusted + historical archive and leaves its header/footer metadata outside the current + authenticated boundary. +- The 5.2.2 reader retains compatibility parsers for the fixed-width disk index + and encrypted-dedup linear AAD sequence published through 5.2.1. An actual + v5.2.1 password-encrypted DATA/DATA/REF/DATA disk fixture is stored as hexadecimal + text with source and hash provenance. The candidate lists, tests, extracts, and restores + it byte-exact, with a warning that the legacy index has no whole-image hash; + the full local Linux gate passed on commit `ff99770`. Older readers are not + claimed to accept new flag-gated 5.2.2 records, and untested historical mode + combinations remain unclaimed. + +Historical test counts in the changelog describe those releases. They do not +automatically become 5.2.8 results; current outcomes belong in the release +validation record, with unavailable environments marked `SKIP`. In particular, +runs made before the final positional-AAD and mandatory-AIT changes are not +final release gates for the resulting candidate. + +## Reporting security issues + +Email **zupt@riseup.net** with `[security]` in the subject.

--selftest ] .SH DESCRIPTION .B zupt-gui -is a graphical frontend for +is a Python Qt 6 frontend for .BR zupt (1). -It provides tabs for compression, extraction, key management, and -full-disk backup. Both PQ encryption modes are exposed: -.B legacy --pq -and -.B SDK v2 --pq-sdk -(HKDF combiner, key commitment, HPKE binding, Argon2id). - -If -.I ARCHIVE -is given on the command line, the GUI opens directly on the -extract tab with that archive preloaded. - -.B zupt-gui -uses Qt 6. It works with either of the following Python Qt bindings, -auto-detected at startup in this order: -.IP \(bu 2 -PySide6 (Qt for Python) -.IP \(bu 2 -PyQt6 +It creates, inspects, verifies, and extracts archives by running the CLI as a +child process. It can also request CLI disk backup and restore operations. +The GUI does not implement an archive codec or cryptography itself. .PP -If neither is installed, the GUI prints an instructive error and exits. - +PySide6 is tried first and PyQt6 is used as a fallback. The selected +.B zupt +command is checked by executing +.BR "zupt version" . +The ZUPT command and environment variables are preferred; renamed-era names +are accepted only for compatibility with an existing installation. +.PP +When paired with the source-only baseline CLI, the frontend uses a build with +.B WITH_SDK=0 +and +.BR WITH_PQBOX=0 . +Native password, +.B --pq +(ML-KEM-768 plus X25519), and +.B --pq-only +(ML-KEM-768) modes remain available. The GUI parses the CLI's +.B Build integrations: +line and exposes +.B --pq-sdk +or +.B --pq-box +only when libvuptsdk or libpqvaptvupt is independently reported enabled. +These two optional integrations are detected separately. +.PP +The gated 5.2.8 GUI release set is limited to the architecture-independent DEB, +noarch/source RPM, and source-only portable ZIP named in the project README. +Package gates require exact checks and installed off-screen GUI/CLI integration. +The portable ZIP receives source scans, an exact safe-member allowlist, and an +extracted launcher test; it bundles no Python, Qt, CLI, or compiled runtime. +AppImage, AppDir and Flatpak bundles and Windows/macOS GUI installers are not +promoted; the Windows ZIP and macOS DMG are CLI-only. +.PP +The GUI does not expose the CLI's recovery-only +.B --allow-legacy-no-ait +option. A known, trusted pre-AIT archive must be recovered explicitly with the +CLI; untrusted trailerless archives must remain rejected. +.SH OPTIONS +.TP +.B --compress +Open the Compress tab with the remaining arguments selected as inputs. +.TP +.B --extract +Open the Extract tab with the following archive selected. +.TP +.B --selftest +Create the complete interface, run the event loop briefly, and exit. A display +backend (or a suitable off-screen Qt backend) is still required. +.TP +.BR --version , " -V" +Print the GUI, Qt binding, CLI version, and selected CLI path. +.TP +.BR --help , " -h" +Print command-line usage. .SH TABS .TP +.B Keys +Generate and export recipient keys. Mode choices follow CLI capability +detection, including independent SDK and PQ-box choices when enabled. +.TP .B Compress -Select files or directories, choose codec, level, password and/or PQ -key. The -.B Mode -panel controls whether the SDK v2 path or the legacy path is used. +Choose inputs, destination, codec options, password, and an optional recipient +public key. .TP .B Extract -Open a .zupt archive, select output directory, provide password -and/or PQ private key. +Choose an archive, output directory, and any required password or private key. +The GUI uses +.B zupt info +to auto-detect supported archive protection modes. That framing inspection is +unauthenticated and is only a mode-selection hint; the subsequent CLI extract +or test operation performs the required AIT and content validation. .TP -.B Keygen -Generate ML-KEM-768 + X25519 keypair. The -.B SDK v2 format -checkbox controls whether the keypair is generated via -.B zupt keygen --sdk -(producing -.IR file -and -.IR file.pub -in one step) or via the legacy -.BR "zupt keygen" . +.B Verify +Inspect an archive header or run the CLI integrity test with the detected +credential type. .TP .B Disk -Full-disk backup and restore. Enumerates block devices with -human-readable sizes. Same encryption mode controls as Compress. - +Request full-device or image backup and restore through the CLI.

Two PQ encryption modes are -supported: a legacy combiner kept for backward compatibility, and a -state-of-the-art mode backed by libzuptsdk (HKDF-SHA3 hybrid combiner with -domain separation, key commitment, HPKE binding RFC 9180, anti-fault -decapsulation, and Argon2id RFC 9106 password derivation). - +creates self-contained backup archives with the historical +.B .zupt +extension. Version 5.2.2 restores the original product name, ZUPT, and the +primary installed command is +.BR zupt . +The archive extension and +.B ZUPT +format magic, codec identifiers, and archive compatibility remain unchanged. +. +.PP +Plain archives provide compression checksums for accidental-corruption +detection. They do not provide cryptographic authentication against an attacker +who can rewrite an archive. Encrypted archives use AES-256-CTR with +HMAC-SHA256 and authenticate current per-block framing, logical frame position, +and archive metadata. The validating read paths require an archive-integrity +trailer by default; a no-trailer archive fails closed unless the caller selects +the explicit trusted-legacy override described below. +See +.B SECURITY.md +and +.B THREAT_MODEL.md +for the exact boundary and historical-format limitations. +. +.PP +The bundled compression codec is VaptVupt codec 2.65.3. +Automatic codec selection uses VaptVupt where the supported AVX2 or NEON path +is available and uses the portable LZHP codec otherwise. Use a codec-selection +option only when a specific choice is required. +. +.PP +The renamed-era +.B vaptvupt +command is an optional compatibility alias and is not installed by default. +Distribution packages, including the openSUSE main package, expose +.B zupt +as the canonical command. +. +.PP +Git and the upstream source tarball are source-only. Separately built CLI DEB, +binary RPM, SRPM, notice-bearing Linux tar.xz, Windows ZIP, and macOS DMG assets +may be published from the immutable tag only after their target-specific gates +pass; they never enter Git or the source tarball. An AppImage is not promoted +for 5.2.8; neither are AppDir/Flatpak bundles, GUI platform installers, or bare +Linux/Windows executables. The Python/Qt frontend remains available as source; +its gated architecture-independent DEB, noarch/source RPM, and source-only +portable ZIP are included in the release claim. The portable ZIP contains no +Python, Qt, CLI, or compiled runtime. Windows and macOS artifacts remain +CLI-only. +. .SH COMMANDS .TP -.B compress, c -Create a compressed archive from one or more files or directories. +.BR compress , " c" +Create an archive from one or more files or directories.

The portable ZIP contains source, launchers, icons, licenses, +and provenance only; it bundles no Python, Qt, CLI, or compiled runtime. Its +gate scans the assembled and extracted trees, enforces an exact safe-member +allowlist, and runs the extracted launcher off-screen against the tested CLI. +An absent artifact did not pass its gate and must not be inferred from another +format's result. + +GUI AppImage, AppDir and Flatpak bundles, and Windows/macOS GUI installers are +not promoted by the upstream 5.2.8 release gates. +`packaging/build-gui-appimage.sh` is a downstream-only helper and fails unless +its operator supplies the exact verified runtime plus a complete +license/source-relink notice through `APPIMAGE_RUNTIME_COMPLIANCE_FILE`; that +material is included in the resulting AppDir. + +The downstream Windows GUI helper similarly requires +`ZUPT_WINDOWS_RUNTIME_NOTICES_DIR` with a `MANIFEST.txt` that identifies +the exact Python, PyInstaller, Qt and PySide/PyQt runtime inputs and their +notices. It fails unless the directory also has non-empty +`PYTHON-NOTICE.txt`, `PYINSTALLER-NOTICE.txt`, `QT-NOTICE.txt`, and either +`PYSIDE6-NOTICE.txt` or `PYQT6-NOTICE.txt`. The installer includes that +directory together with every ZUPT license and notice. This requirement does +not make the untested GUI installer a 5.2.8 release asset. The promoted Windows +ZIP and macOS DMG are CLI-only. + +Packaging recipes and scripts under `gui/packaging/` and `packaging/` are build +inputs, not evidence that a package has been accepted by a distribution. They +must build the CLI from the immutable source tag with +`WITH_SDK=0 WITH_PQBOX=0` unless source-built system dependencies are declared. +Generated packages, application bundles, and executables must remain outside +Git and outside upstream source archives. + +The former standalone `gui/setup.py` sdist/wheel route is intentionally absent: +its outputs did not carry the complete project license payload.

Its primary URL is the canonical upstream: + +```text +https://github.com/cristiancmoises/zupt.git +``` + +`obs_scm` stores an `.obscpio` plus `.obsinfo`. The `tar` and `recompress` +services reconstruct `zupt-5.2.8.tar.gz` inside the build environment, which +matches `Source0` in the spec. + +This source policy does not prohibit separately built release-page packages. +The upstream 5.2.8 gates may publish the CLI source tarball, DEB, binary RPM, +SRPM, notice-bearing Linux tar.xz, Windows ZIP, and macOS DMG, together with a +GUI DEB, noarch RPM, GUI SRPM, and source-only portable GUI ZIP after each +format-specific test succeeds. None of those files is an OBS `Source0` input +or belongs in Git. AppImage and bare executables remain excluded: the former +lacks an audited runtime source/relink handoff, while the latter does not carry +the required license and notice payload beside the program. + +## License and bundled codec + +The resulting executable combines the AGPL-3.0-or-later application with the +GPL-3.0-or-later VaptVupt codec, adapted BSD-2-Clause XXH64 routines, and +CC0-1.0 pq-crystals/kyber-derived ML-KEM portions, plus BSD-3-Clause +curve25519-donna-derived X25519 portions, so the RPM uses: + +```text +AGPL-3.0-or-later AND GPL-3.0-or-later AND BSD-2-Clause AND BSD-3-Clause AND CC0-1.0 +``` + +The bundled codec is VaptVupt codec tag `v2.65.3`. It was integrated into this +repository by commit `59f9ebc59ea13c6edf1d199ca795cdbf00e62226` and is declared +as `bundled(vaptvupt-codec) = 2.65.3`. That integration commit records the local +ANS safe-zone reserve patch applied on top of the upstream tag. The package +retains all license and notice files, including Yann Collet's xxHash notice; +it does not claim that the codec is unbundled. + +## Optional SDK and PQBOX integrations + +The OBS package always builds with: + +```text +WITH_SDK=0 WITH_PQBOX=0 +``` + +The resulting CLI retains the in-tree password, ML-KEM-768, X25519 and hybrid +features. It does not enable the optional libvuptsdk-backed Argon2id/`--pq-sdk` +integration or the separate libpqvaptvupt-backed `--pq-box` integration. Those +options may only be enabled in a future package after their complete source or +system development packages, licenses, ABI and dependencies have been audited. +The build does not download dependencies and never loads a repository-local +`.so`, `.a` or `.o` fallback. + +## Archive integrity and compatibility in 5.2.2 + +New encrypted archives bind every DATA and DEDUP_REF frame to its logical +position. An authenticated reference also carries the authenticated position of +the source DATA frame, and new disk archives use flag-gated index/content-hash +metadata. The on-disk version byte remains 1.6, but an older reader is not +claimed to accept every new 5.2.2 encoding. + +The packaged `extract`, `list`, `test`, and `disk restore` paths require an +archive-integrity trailer by default, without trusting unauthenticated header +flags. `--allow-legacy-no-ait` is accepted only by those commands for recovery +of a known, trusted pre-AIT archive and emits a downgrade warning. `info` merely +reports unauthenticated framing and apparent AIT presence; it does not validate +the trailer or contents. Package documentation must not recommend the override +for untrusted input or present `info` success as an integrity result. + +The separate v5.2.1 compatibility claim is narrow: an actual +password-encrypted, deduplicated DATA/DATA/REF/DATA disk archive created from the +immutable v5.2.1 tag is stored as hexadecimal text with its source and SHA-256 +provenance. The 5.2.2 reader reconstructs the legacy linear block-AAD sequence, +lists, tests, extracts, and restores its input byte-exact through the +fixed-width legacy disk-index parser. This does not cover every historical mode +and passed in the full local Linux gate for commit `ff99770`; the target RPM +`%check` must still exercise it before that package is promoted. + +Disk restore also snapshots the measured archive into a private scratch file +before opening the destination, then validates and restores from that same +stream. An invalid `ZUPT_TMPDIR` override (or the compatibility fallback +`VAPTVUPT_TMPDIR`) and an unknown or insufficient raw-device capacity fail +before the first target write. The package check covers +the unprivileged unknown-capacity path; its loop-device size regression is +reported `SKIP`, not `PASS`, when the builder cannot create a loop device. + +## Migration from the former package name + +The main package is named `zupt` and installs only `/usr/bin/zupt`, its man +page, and its completions. The spec has a versioned `Provides: vaptvupt` and +`Obsoletes: vaptvupt` so an installed package under the former public name can +upgrade cleanly. It intentionally does not claim or install a second +`/usr/bin/vaptvupt` executable. The bundled codec and optional library keep +their established VaptVupt identifiers because those are compatibility-facing +API names, not the application package name. + +## Local validation workflow + +Run these commands in an OBS package checkout, not in the upstream Git tree: + +```sh +xmllint --noout _service +osc service manualrun +rpmspec -P zupt.spec >/dev/null +spec-cleaner --diff zupt.spec +osc build --clean --keep-pkgs="$PWD/.osc-build-results" \ + openSUSE_Tumbleweed x86_64 +rpmlint .osc-build-results/*.rpm +``` + +`osc service manualrun` materializes the service marked `manual` (the pinned +SCM input). The tarball itself is +reconstructed by the build-time services. Neither `%build` nor `%check` may +access the network. + +For a source RPM check outside OBS, place the service-produced +`zupt-5.2.8.tar.gz` next to the spec and use a disposable RPM build tree: + +```sh +rpm_top=$(mktemp -d) +trap 'rm -rf -- "$rpm_top"' EXIT +mkdir -p "$rpm_top"/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS} +rpmbuild --define "_topdir $rpm_top" --define "_sourcedir $PWD" \ + -bs zupt.spec +``` + +After building, inspect the RPM contents and dependencies, run `rpmlint`, then +install it in a disposable openSUSE environment and execute +`scripts/test-installed-zupt.sh`. Do not claim a repository or architecture +as supported until its build and installed smoke test have actually passed. + +## Prior 5.2.2 committed-candidate local Linux validation + +The immutable 5.2.2 candidate at `ff99770` passed the full local +`make release-check`. Packaging policy +and syntax reported `PASS=49 FAIL=0 SKIP=0`; source-only scanner testing passed +39/39, including GNU thin archives and safe diagnostic cases; strict GCC, +strict Clang, GCC `-fanalyzer`, the 9/9 full tool-enabled static-analysis run, +ASan/UBSan/LSan, and 1,000 mutation-fuzz iterations passed. A reduced +environment completed six available static checks and reported `cppcheck` +unavailable rather than passing it. Earlier off-screen GUI smoke evidence is +supporting evidence, not an exact-commit package result. + +Post-tag CI integration failures prevented 5.2.2 promotion. These historical +local results do not establish 5.2.8, native Windows or macOS success, hosted +GitHub CI/release promotion, authenticated OBS acceptance, or resolution of the +automatic openSUSE `debugsource` rpmlint `no-binary` finding. The immutable +5.2.3 candidate was not promoted because its source-policy test assumed LF for +a Windows `.bat` file checked out as CRLF. + +## Prior 5.2.4 exact-tag source-service evidence + +The immutable v5.2.4 candidate was not promoted. Exact-tag GitHub Actions run +`33431386002` recorded 12 successful jobs and one failed openSUSE job. That job's +standalone `Serviceinfo` harness passed the service directory to the executor +but did not make it the process working directory; dependent native Windows and +macOS jobs were skipped. + +A disposable local openSUSE Tumbleweed reproduction independently resolved +`refs/tags/v5.2.4` to the tagged commit. With `osc` 1.27.3, +`obs-service-obs_scm` 0.12.4, `obs-service-tar` 0.12.4, and +`obs-service-recompress` 0.5.2 installed, the same executor completed +`obs_scm`, `tar`, and `recompress` after `os.chdir(service_dir)`. It produced +exactly one `zupt-5.2.4.tar.gz`; its SHA-256 was +`aa68a58fc2e88ee92296542de1f189e2b8a803154d832fb04d5296b25acaef8f`, and the +source scanner reported `PASS source-only: 204 files, 1 archives`. + +This result establishes that the explicit tag revision works and isolates a +release/test harness defect. It does not change the product, archive format, +cryptography, codec, or SDK ABI; it does not make skipped native jobs pass or +establish authenticated OBS/Factory acceptance. No v5.2.4 evidence transferred +automatically to v5.2.8; the exact candidate later repeated every applicable +upstream gate in run `33456209269`, as recorded below. The automatic openSUSE +`debugsource` rpmlint `no-binary` finding remains unresolved and unsuppressed. + +## Prior 5.2.5 exact-tag native-gate evidence + +The immutable v5.2.5 candidate was not promoted. Exact-tag GitHub Actions run +`33434986357` completed 13 jobs successfully and failed the native Windows and +macOS jobs. Windows exposed a hostile-path fixture that did not preserve its +requested bytes across the command-line boundary; macOS exposed the unsupported +`explicit_bzero` assumption and Bash 3.2 empty-array handling. The 5.2.6 +corrections address those release/test integration defects without an archive, +cryptographic, codec, or SDK ABI change. + +## Prior 5.2.6 exact-tag native-gate evidence + +The immutable v5.2.6 candidate was not promoted. Exact-tag GitHub Actions run +`33442264243` completed 13 jobs successfully and failed two native jobs. The +macOS arm64 SHA-NI test build treated unused x86-only helper declarations as +errors under `-Werror`; Windows argv transcoding aborted the safe printable +UTF-8 fixture before its intended path assertions. The 5.2.7 changes correct +those test-harness boundaries without an archive-format, cryptographic, codec, +or SDK ABI change. They do not establish 5.2.8 hosted, native, OBS, or promotion +evidence. + +## Prior 5.2.7 exact-tag native-gate evidence + +The immutable v5.2.7 candidate was not promoted. Exact-tag GitHub Actions run +`33445470664` concluded `cancelled` at `2026-08-31T23:11:19Z`, with 13 +successful jobs, one failed macOS job, and one cancelled Windows job. macOS +rejected creation of the raw-C1 scanner fixture +with `EILSEQ`; the hosted Windows job stalled in `make check`, and a MinGW/Wine +reproduction isolated the cause to a redirected password prompt entering +`_getch`. Version 5.2.8 makes those test +boundaries fail or skip without hanging, addresses CodeQL High #5/#6/#7 in SDK +key publication, disk restore, and benchmark cleanup, and adds `sdk-test` to +release and hosted Linux gates. None of those changes establishes an exact +5.2.8 OBS, native, hosted-CI, or promotion result. + +## 5.2.8 exact-tag upstream package evidence + +Manually dispatched exact-tag GitHub Actions run `33456209269` passed all 15 +jobs at `ebb9ab3aa1d42c50030ca02883f6162dc4771fe1`. Its openSUSE Tumbleweed +x86_64 job parsed and normalized the spec, executed the pinned standalone OBS +source-service chain, source-scanned the resulting archive, built the binary +RPM and genuine SRPM, ran `rpmlint` without suppressions, and completed the +install/round-trip/uninstall test. The canonical source archive is 798296 bytes +with SHA-256 +`378b9506211545b9594cf0d38ac8955d9b1cac34eb6b379ae0ec26b84edb65f7`. + +Promotion run `33457868306` published the exact tested binary RPM and SRPM with +the other gated assets. The source package is identified by +`%{SOURCEPACKAGE}=1` and an absent `%{SOURCERPM}`; its `%{ARCH}` legitimately +reflects the spec's build architecture and is not the SRPM discriminator. +Repository, Git archive, and upstream source tarball scans remain binary-free. + +This is upstream local-service and package evidence, not a claim that the +package was submitted to or accepted by openSUSE Factory, nor a result for the +full set of automatically generated OBS debug packages or any untested +architecture. + +## Prior openSUSE packaging validation + +The local results below were produced on 2026-08-24 from the 5.2.2 candidate +snapshot captured for the packaging run, in a disposable openSUSE Tumbleweed +20260822 x86_64 container. This matrix was documented afterward, so the results +validate that captured snapshot, not the later documentation edit, a future +commit or a tag.

Exact-tag hosted, + native-platform, package, and promotion gates must pass before release or + downstream handoff; the tag itself is never moved to repair a failure. +2. With Git, `file`, bsdtar, tar, zip, unzip and SHA-256 tools installed, run + `scripts/export-opensuse-package.sh v5.2.8`. Verify the reported ZIP and + SHA-256 outside the Git index.

From the extracted handoff root, run + `packaging/opensuse/source-audit.sh --archive /path/to/zupt-5.2.8.tar.gz`. + Then copy `_service`, `zupt.spec`, `zupt.changes` and `README.md` + into the flat OBS package checkout.

The C-source identifier prefix (zupt_, ZUPT_) is also + unchanged for ABI continuity with libzuptsdk. + * Legacy /usr/bin/zupt symlink installed alongside vaptvupt for + one major version cycle. + * Integrated VaptVupt LZ + ANS codec 2.48.5: fixes csz==0 heap- + buffer-overflow READ in vv_dstream_decompress_chunk (libFuzzer- + found, medium severity), UBSan-safe pointer arithmetic in + vv_copy_match, const-correctness cleanup in vv_ans entropy + encoder. + * Enhanced manpage (597 lines, was 422).
