- Remove is_dm column from channels table (dm detection by member count)
- Rename member name column to userinfo — extensible json_flat format
- Add json_flat.c/h library for compact JSON serialization
- Fix join_sig message format: use ch_x25519+ch_ed25519 instead of channel_id string
- Remove name from join_msg body (now in userinfo via json_flat)
- Update chat_core, chat_sync, member_sync, db_manager to new format
- Add topo_strategy.txt — архитектурные заметки по топологии
- CHAT groups don't send subnets and skip route insert/delete
- Group type mismatch sends ERR_GROUP_MISMATCH to peer
- New topo_groups_create_group() public API for creating typed groups
- Renamed TOPO_BGP to TOPO_GROUP with topo_group_id (64bit)
- Added TOPO_GROUPS container (ll_queue group_list) in UTUN_INSTANCE
- Memory pools moved from TOPO_GROUP to TOPO_GROUPS (instance-level)
- Default group: TOPO_GROUP_UTUN = 0x8000000000000000
- topo_groups_get_default() searches by group_id, not just first entry
- All topo_bgp_* renamed to topo_group_*; function signatures updated
- Files: topo_bgp.h/c -> topo_group.h/c
- 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
Added #ifdef __cplusplus / extern "C" { ... } / #endif to ~65 headers
in src/ and lib/, enabling the C library to be linked into C++ code (chatgui).
Fixed packet_dump.h (added missing header guard) and etcp_bbr.h
(#pragma once guard).
- route_node_format_all(): format all BGP nodes to snprintf buffer
- control_server: 'nodes' action sends ETCPMON_RSP_ACTION_RESULT (0x89) with text
- etcpmon_protocol.h: new response type + struct, increase MAX_MSG_SIZE to 32K
- etcpmon_client: on_action_result callback, send_action via send_request with seq_id
- etcpmon_gui: ETCPMonActionResult popup window class with EDIT multiline,
on_action_result creates popup (same size as main) or appends text + scrolls
Add route_node_dump_all() in route_node.c that walks bgp->nodes list
and outputs per-node info: node_id, name, version, pubkeys, IPv4/IPv6
addrs/sockets/subnets, paths with hop list, connectivity state, conn_mgr.
Wire 'nodes' action in control_server to call this function.
- Add ed25519_public_key[32] to NODEINFO struct for pubkey distribution
- Add ed25519_public_key[32] to ROUTE_BGP (derived from X25519 privkey at init)
- Add ROUTER_FLAG_SIGNED (0x08) to SVC_ROUTE_HDR flags byte
- router_send_one_flags: when is_signed, sign [hdr][payload] and append 64-byte sig
- etcp_router_recv_cb: verify Ed25519 signature when ROUTER_FLAG_SIGNED set
- New API: etcp_router_conn_send_signed()
- Drop signed packets if sender node not in routing table or no Ed25519 key
- 5 unit tests in test_etcp_router_unit.c covering OK/tampered/unknown/no-key/short
- Rename NAT types: OPEN->EIM, RESTRICTED->STRICT across all code
- Add flat addr list {type,ip,port,socket_id} to NODEINFO (NODEINFO_IPV4_ADDR)
- Add NODEINFO_IPV4_SOCKET_META for per-socket metadata
- Add NODE_CONNECTIVITY with per-type probe status and min_rtt
- New module: route_connectivity.c/h (probing engine with socket fallback)
- STRICT verified addresses excluded from NODEINFO broadcast
- Trigger probing on new/updated BGP node, cancel on remove/withdraw
- Update NAT type names in etcpmon GUI
- Add get_node_v6_sockets() function in route_node
- Add local_defaultroute_ip6 field to ETCP_SOCKET
- Fix IPv6 address logging in bind, init, new connection
- Fix socket lookup for IPv6 in init_connections
- Fix route_ping_handle_req to support both v4 and v6 sockets
- Replaced old BGP_ROUTE_PACKET with NODEINFO packets
- Added paths list to NODEINFO_Q for multi-path routing
- Implemented process_nodeinfo, process_withdraw, add/remove_path
- Updated routing.c to use v_node_info->paths
- Fixed type inconsistencies and includes across route_* files
- Hash size for nodes queue increased to 256
- Version increment logic in build_my_nodeinfo
Branch: feature/nodeinfo-routing
