- Each migration runs in a transaction. Several rebuild the profiles
table (create, copy, DROP, rename); a crash between the DROP and the
rename left a database that failed to open on every later launch.
- Migration 009 removes the Go-era proxyPassword/totpSecret keys still
sitting in old ssh_config JSON, then VACUUMs and checkpoints the WAL so
the old pages leave the file. secure_delete is on from now on.
- nexus.db (and -wal/-shm) are created and kept 0600.
- Profile ids are limited to [A-Za-z0-9._-]{1,64}: ids name keychain and
vault entries (profile:<id>:<kind>), so a crafted id containing ':'
could shadow or purge another profile's credentials on import/sync.
- Hosts reject control characters (NUL got through) and >253 bytes; jump
hosts and forward destination/bind addresses get the same host check.
RDP profiles can go through a Remote Desktop Gateway (MS-TSGU over an
HTTPS WebSocket) with its own username and password, stored like other
credentials (rdp-gateway-password). The gateway stream is bridged to a
loopback socket so the blocking RDP client uses it like any transport.
IronRDP's gateway crate (0.0.1) is vendored with fixes: it used
ironrdp-tls, which accepts any certificate, before sending Basic
credentials — the gateway is now verified against the web PKI; its
asserts on gateway-supplied lengths are errors instead of panics; and
the server port is passed through. Checked against a self-signed
openssl s_server: the connection is refused ('invalid peer certificate')
before any request or credential is sent. Not tested against a real
gateway; Basic-auth gateways only (no NTLM).
- Audio: the RDPSND channel with IronRDP's cpal playback backend (PCM;
Opus left out to avoid another native library). On by default for new
RDP profiles. Building now needs the ALSA headers on Linux
(libasound2-dev), added to CI, release and fuzz jobs and the build docs.
- Shared folder (Linux/macOS): one local folder appears on the remote
desktop as a drive. IronRDP's native backend joins server paths onto
the share unchecked, so it is wrapped in ConfinedDrive: create, list
and rename paths with '..' components, NUL bytes, or that resolve
through a symlink outside the share are refused (ACCESS_DENIED);
tests cover the escapes.
Verified against xrdp (with FUSE): the remote read the shared file, and
writes, mkdir and rename landed in the local folder. Not verified:
audio playback (the test container has no sound module), and xrdp lists
the drive as 'ignored' and can't list its directories (an IronRDP/xrdp
naming and listing mismatch, fixed upstream for the name).
- Protocol::Rdp with RdpConfig (domain, password mode, certificate
policy, TLS-only fallback, fixed or tab-sized resolution, SOCKS5/HTTP
proxy, SSH tunnel); migration 008 adds rdp_config and drops the
protocol CHECK constraint so new protocols no longer need a rebuild.
- Session manager: connect_rdp dials directly, via the shared proxy
module (proxy password from the secret store) or an SSH tunnel; the
server certificate goes through the known-hosts check (key type
rdp-tls); a tab-sized desktop uses the tab's reported pixel size, and
resizes wait until the server opens Display Control. Rejected NLA
passwords count as auth failures, so a saved one is asked again.
- The VNC viewer becomes DesktopView for both protocols; a small adapter
turns its keysyms and pointer masks into RDP scancodes, Unicode keys,
buttons and wheel events. For RDP, Paste Clipboard types the text.
- Profile editor RDP section, Quick Connect, badges, docs.
Verified against xrdp in the app: logon, desktop, input, and connections
through SOCKS5 and HTTP CONNECT relays. Not verified here: Windows/NLA
servers, the SSH tunnel route, and Display Control resizing (xrdp
0.9.24 never opened the channel).
