Colloid-Catppuccin theme loaded via ~/.config/gtk-4.0/gtk.css at
PRIORITY_USER (800) was overriding moonlock's PRIORITY_APPLICATION (600),
causing avatar to lose its circular border-radius.
- Use STYLE_PROVIDER_PRIORITY_USER for app CSS provider
- Replace border-radius: 50% with 9999px (GTK4 CSS percentage quirk)
Wallpaper is installed by moonarch to /usr/share/moonarch/wallpaper.jpg.
Embedding a 374K JPEG in the binary was redundant. Without a wallpaper
file, GTK background color (Catppuccin Mocha base) shows through.
Close the only exploitable auth bypass: validate VerifyStatus signal sender
against fprintd's unique bus name. Fix fingerprint D-Bus lifecycle so devices
are properly released on verify-match and async restarts check the running
flag between awaits.
Security: num_msg guard in PAM callback, symlink rejection for background_path,
peek icon disabled, TOML parse errors logged, panic hook before logging.
Performance: blur and avatar textures cached across monitors, release profile
with LTO/strip.
Gaussian blur applied at texture load time when `background_blur` is
set in moonlock.toml. Refactored wallpaper loading from per-window
Picture::for_filename() to shared gdk::Texture pattern (matching
moonset/moongreet), avoiding redundant JPEG decoding on multi-monitor.
Move all fprintd D-Bus calls (init, availability check, claim, verify)
from synchronous to async using gio futures. Windows now appear
immediately without waiting for D-Bus — fingerprint label fades in
once fprintd is ready. Single shared FingerprintListener across all
monitors instead of one per monitor.
PAM conv callback: check msg_style (password only for ECHO_OFF),
handle strdup OOM with proper cleanup, null-check PAM handle.
Fingerprint: self-wire D-Bus g-signal in start() via Rc<RefCell<>>
and connect_local — VerifyStatus signals are now actually dispatched.
VerifyStop before VerifyStart in restart_verify.
Lockscreen: password entry stays active after faillock threshold
(PAM decides lockout, not UI), use Zeroizing<String> from GTK entry.
Release builds exit(1) without ext-session-lock-v1 support.
Config: fingerprint_enabled as Option<bool> so empty user config
does not override system config.
Dead code: remove unused i18n strings and fingerprint accessors,
parameterize faillock_warning max_attempts.
Complete rewrite of the Wayland lockscreen from Python/PyGObject to
Rust/gtk4-rs for memory safety in security-critical PAM code and
consistency with the moonset/moongreet Rust ecosystem.
Modules: main, lockscreen, auth (PAM FFI), fingerprint (fprintd D-Bus),
config, i18n, users, power. 37 unit tests.
Security: PAM conversation callback with Zeroizing password, panic hook
that never unlocks, root check, ext-session-lock-v1 compositor policy,
absolute loginctl path, avatar symlink rejection.
