Fix 1 — NixOS: store/ dir missing from ReadWritePaths
archive_path points to .archivr/; captures write artifacts to the
sibling store/ directory. Whitelisting only .archivr/ caused POST
/captures to fail under ProtectSystem=strict.
Fix: use builtins.dirOf a.path to whitelist the parent, which
contains both .archivr/ and store/.
Fix 2 — Rust: X-Forwarded-For was unconditionally trusted
An attacker could send a different IP on every login attempt,
bypassing LOGIN_MAX_ATTEMPTS entirely.
Fix: use ConnectInfo<SocketAddr> (via into_make_service_with_connect_info)
as the primary rate-limit key; XFF is trusted only when the TCP peer
is loopback (i.e. a local reverse proxy). Tests without a real socket
fall back to XFF unchanged.
Port configuration:
NixOS module: split 'bind' string into separate 'listenAddress'
(default 127.0.0.1) and 'port' (default 8080) options. openFirewall
now uses cfg.port directly instead of parsing it from the bind string.
README NixOS example updated accordingly.
modules/nixos/archivr-server.nix — services.archivr-server NixOS module:
- enable/bind/archives/user/group/openFirewall options
- generates archivr-server.toml from options via pkgs.writeText
- pins auth DB to /var/lib/archivr-server/ (StateDirectory)
- dedicated archivr system user + group
- hardened systemd unit: ProtectSystem=strict, NoNewPrivileges,
PrivateTmp, RestrictNamespaces, etc.; archive paths whitelisted
- openFirewall parses the port from the bind string automatically
flake.nix:
- add self to outputs args
- add aarch64-linux to systems (Raspberry Pi / ARM servers)
- expose nixosModules.archivr-server + nixosModules.default
.gitignore: whitelist modules/ directory
docs/README.md: add 'Hosting on NixOS' section with full example
