- NODEINFO_MSG (protocol, packed): added flags byte + group_id field
- NODEINFO (memory): ref_count, linked list heads instead of inline arrays
- NODEINFO_ROUTES: separate struct with linked list subnet heads
- NODEINFO_Q: node*, routes*, tranzit_data*, hop_list* as separate mallocs
- 6 memory_pools in ROUTE_BGP for NI_* linked list items
- ni_list_count() universal counter via _ni_head cast
- nodeinfo_serialize/deserialize for protocol <-> memory conversion
- NODEINFO_FLAG_SEND_SUBNETS controls subnet data in protocol
- group_id defaults: utun=NODEINFO_GROUP_UTUN(1) with subnets
Fixes:
- deserialization: data+2 instead of data+sizeof(BGP_NODEINFO_PACKET)
- memset: start after ll_entry to preserve ll.size
- hop_src: subtract hop_count*8 to point at correct dynamic offset
- same-ver branch: remove_path(conn) instead of remove_path_by_hop(peer)
- double-free in route_bgp_remove_conn/process_withdraw
- conn_mgr_add_alien_node: rewritten for new structures
- all test files updated for new API
- keepalive_adaptive=0 disables adaptive keepalive period growth,
keeping it fixed at 200ms for faster timeout detection in tests
- test_bgp_triangle: 5-node triangle topology test (6 phases):
validates alternative path recording (fix#1), cascading node
removal on full isolation, and full recovery
- config generation via utun_instance_create_from_str() with
pre-generated keys — no temp files needed
