Root cause: kiosk never stored cluster_key from pairing response.
Bundle ships onvif_password_encrypted (AES-256-GCM with cluster key).
decrypt_cluster was a stub returning None → empty password → WSSE auth
fails → CreatePullPoint rejected → no events ever.
Fix:
1. ClaimResp now includes cluster_key field
2. Stored encrypted at rest alongside kiosk_key (at_rest.rs)
3. Loaded at bundle render, passed to onvif_events::start()
4. decrypt_cluster implements full AES-256-GCM: parse v1.<iv>.<tag>.<ct>
format, base64url decode, decrypt with cluster key
Also: removed BF_ENABLE_ONVIF_EVENTS env gate — if camera is type=onvif
with onvif_host, subscribe. Gate was redundant with the type filter.
Also: bump Angie proxy_read_timeout to 600s on /api/admin/ for OS
bundle import (downloads ~1GB from GitHub, was timing out at 60s).
NOTE: existing paired kiosks won't have cluster_key stored. They need
to re-pair (delete + re-add) to receive it. New pairings get it
automatically.
New kiosk/src/onvif_events.rs: for each ONVIF camera in the bundle,
creates a PullPoint subscription, polls every 3s, parses
NotificationMessage XML into structured JSON (topic + source key/values
+ data key/values + timestamp), and POSTs to /api/kiosk/event with
source_type=onvif + camera_id.
Forwards ALL event topics: motion, ANPR (LicensePlateRecognition),
line crossing, intrusion, digital input, analytics, tamper — everything
the camera exposes. Node-RED sorts what matters.
Subscription lifecycle:
- CreatePullPointSubscription with 60s InitialTerminationTime
- Renew every 55s before timeout
- Unsubscribe on bundle change / shutdown
- Auto-resubscribe on pull/renew failure (30s backoff)
- Generation tracking via Weak<()> so old workers self-terminate
when start() is called with a new bundle
WSSE PasswordDigest auth for SOAP calls — same scheme the server's
onvif.ts uses. sha1 crate added.
BundleCamera extended with onvif_host/port/username/password_encrypted
fields (server already ships them; kiosk just wasn't deserializing).
Gated by BF_ENABLE_ONVIF_EVENTS=1. Enabled by default in the pi-gen
image env file.
TODO: cluster-key-based decryption of onvif_password_encrypted. For
now relies on the RTSP URI having plaintext credentials embedded (which
the ONVIF import path already ensures via rtspWithCredentials).
