Deleting or updating a marker no longer triggers a full NIO reapply
(reset_packet_filters + re-add), which closed/reopened every sibling
marker's pcap via uBridge. Instead operate on single filters:
- stop_marker: bridge delete_packet_filter + unlink the pcap (works with
the node stopped; filter removal is skipped, the file is still deleted).
- update_marker: bpf/tag/direction → rebuild just that filter (delete + add);
enabled → instant toggle; color/highlight_duration → stored only.
- compute delete_marker_capture / rebuild_marker_filter + per-node routes
(DELETE /markers/{name}, PUT /markers/{name}/rebuild) + MarkerRebuild schema.
IOU overrides _ubridge_delete_marker_filter for iol_bridge; rebuild reuses
the already-overridden add/delete/set, so IOU needs no rebuild override.
The _marker_filter_bridges dict was keyed by marker name alone, so when one
node hosted the same filter name on several links (IUOL-BRIDGE per node with
many bays/units, or a multi-interface router), successive apply calls
overwrote earlier entries. pause_marker_definition then toggled only the last
recorded bridge/location — other copies stayed active and kept emitting.
Key by (name, link_id) so each copy is independent, and iterate all matching
entries in _ubridge_set_marker_filter_state (both generic bridge and IOU
iol_bridge override). Toggle route existence checks also iterate matching
names. Tests updated.
- compute (test_base_node.py): set_marker_filter_state on/off command,
marker pause/resume command, and apply issues enable_packet_filter off
for a disabled marker (+ records the name->bridge map).
- controller (test_marker.py): _markers_for_node keeps disabled markers
and carries enabled; update_marker enabled-only hits the toggle route
(not NIO rebuild) while a bpf change still rebuilds; pause/resume fan
out to capture nodes.
Direction field in marker.match events
=======================================
Read ubridge dir=<tx|rx> from MARK signal datagrams and forward it
as a "dir" key in the marker.match notification event. The field is
additive -- older ubridge builds omit it and the parser leaves it null,
so consumers fall back to undirected rendering with no version coupling.
Semantics are relative to the capture node (the signal's node=<id>):
tx = capture node is sending (ingressed device-side NIO), rx = it is
receiving (ingressed link-side NIO).
Per-marker direction filter (opt-in, server-side pipeline)
==========================================================
Add a direction field to MarkerCreate and MarkerDefinitionCreate
schemas ("tx" | "rx" | null). Plumb it through the full pipeline:
Schema -> controller (start_marker/update_marker, marker_entry,
_markers_for_node, update_marker_definition sync)
-> REST/MCP handlers -> compute _ubridge_add_marker_filter +
IOU _ubridge_apply_markers -> bridge add_packet_filter dir <tx|rx>
When set, ubridge only fires the mark handler (signal + pcap) for
packets matching the chosen direction. null (default/legacy) = both
directions -- zero behavioural change for existing markers.
Docs and tests
==============
- docs/features/marker-traffic-insight.md: signal format updated,
new Direction section with NIO mapping, arrow mapping, and additive
compatibility note.
- tests/compute/marker/test_marker_manager.py: 3 new parser tests
(dir tx/rx/absent) plus existing test extended to assert dir=None.
13 files, +123/-22, 72 tests pass (zero breakage)
NAT now includes an 'interfaces' field in its response, filtered to
contain only the mapped NAT interface (virbr0 on Linux, vmnet8 on
macOS/Windows). This lets connected nodes discover the NAT subnet
and gateway address without needing to list all host interfaces.
The field format mirrors Cloud.asdict(): name, type, special, and
ip_addresses list (both IPv4 and IPv6).
A uBridge MARK signal carries only node= and filter= (no bridge/link field), so when one node is the capture side for several links that share a marker name (always the case for global-{name} definitions on a multi-interface node) the signals were indistinguishable and the (node, filter) registry collapsed them to a single link.
The mark filter is now stamped with its link id (mark <bpf> ... link <link_id>); uBridge echoes it verbatim (link=<link_id>) and the listener uses the signal's link= as the authoritative link_id of the marker.match event, falling back to the registry only for legacy signals without it. base_node and iou apply paths pass link_id; covered by two new listener tests.
Each host interface surfaced by the cloud node now reports:
- ip_addresses: every IPv4 and IPv6 address (previously only a single
IPv4 was collected internally and then dropped before the response)
- status / speed / mtu / flags: operational state and link attributes
sourced from psutil.net_if_stats(), with flags normalized to a list
The legacy ip_address / netmask / mac_address fields are preserved so
existing callers (compute link detection, GNS3 VM, VMware, has_netmask)
keep working. The new fields travel through the existing interfaces
payload that the controller forwards verbatim, so no controller-side
change is required and the PUT / ports_mapping flow is unaffected.
