Fixes the "GUI functions don't work on GNU Guix" report and a batch of
adversarial-audit findings across the CLI, decoder, crypto and packaging.
GUI (gui/src/zupt_gui.py)
- Root cause of the broken GUI: every encryption path defaulted to the
libzuptsdk "SDK v2" modes, which are absent from the source-only build and
exit 1. Reworked Keys/Compress/Extract around the native modes with a
build-aware PQ-mode selector: Hybrid (--pq, default), Full PQ (--pq-only),
and SDK v2 only when the binary reports WITH_SDK support. Capability is
detected from `version` ("Build:"/"KDF:" lines) with a `help` fallback.
- Extract/Verify gain a PQ private-key input with auto-detect (reads the
archive via `info` to pick --pq vs --pq-only). Verify could not verify any
PQ archive before (password field only).
- run_async now holds a LIST of in-flight (thread, worker) refs; DiskTab's two
buttons previously shared one slot, so a second op GC'd the first QThread
mid-run. About tab corrected (codec 2.60.4, PBKDF2 default, --pq-only, URL).
CLI (src/zupt_main.c)
- compress -p <archive> <files> swallowed the archive name as the password and
truncated the first input file (silent data loss, exit 0). Added a
data-loss guard: refuse to overwrite an existing non-.zupt file as the output
archive unless -y/--force; plus a self-overwrite guard.
- compress <archive> <src> -p <pw> wrote an UNENCRYPTED archive (exit 0)
because options after the first positional were treated as files. Now errors
on a misplaced option (with a `--` escape for real dashed filenames).
- Removed duplicated dead --pq-box/--pq-sdk branches. version/banner/usage now
state the build's real KDF (PBKDF2 on source-only) and repo URL; examples
lead with native --pq / --pq-only.
Security (audit findings)
- vv_decoder.c: the two AVX2 fast-path token decoders read a 2-/3-byte match
offset after only checking 1 byte remained -> heap over-read on a crafted
archive. Added the `ip + off_bytes > ip_end` guard the tail path already had.
- zupt_crypto.c: wipe ML-KEM/X25519 secret-key buffers when hybrid decrypt
init fails on key read (matches the pq-only path).
- zupt_format.c: bound attacker-controlled encryption_header_off before the
(off_t)+7 arithmetic in the info enc_type reader (avoid signed-overflow UB).
Packaging (would fail source-only)
- debian/rules (staged into debian/zupt, installed vendored .so), aur/PKGBUILD,
nix/flake.nix, homebrew (vendored .so + nonexistent AUDIT.md, stale /zupt
URLs) now build source-only. opensuse spec %files ships the shell completions
make install writes (rpmbuild no longer fails on unpackaged files);
_service + debian/control point at the vaptvupt repo; KDF claim corrected.
Cross-platform GUI packaging (new)
- packaging/portable/: OS-agnostic GUI package (zupt_gui.py + .bat/.command/.sh
launchers + README) that runs on Windows/macOS/Linux/BSD with Python+PySide6.
- .github/workflows/cross-platform.yml: builds real native binaries on
windows-latest + macos-latest runners (CLI, PyInstaller GUI, Inno Setup
installer, .dmg) and the portable zip, attaching them to the release on tag.
- packaging/windows/vaptvupt-gui.iss: Inno Setup installer script.
Validation: make check 16/16 (all distro-safe checks), GUI imports + command
contracts verified against the fixed CLI. test_help_consistency updated to
assert the truthful (build-aware) default KDF.
