evgeny 38c9f229bc stcp: ed25519 pubkey exchange in handshake, fix instance destroy segfault, fix chat_tcp_test
- u_async.c: process immediate_queue BEFORE epoll_wait in uasync_poll
- stcp_link.c: defensive NULL etcp_conn/etcp_link in stcp_link_close
- utun_instance.c: move stcp_server_list_destroy_all to Phase J (before ETCP),
  add deferred drain in both Phase J and L
- stcp.h/c: STCP_HS_ENC_CLIENT 6→38, STCP_HS_ENC_SERVER 7→39,
  exchange ed25519_pubkey in both handshake directions
- etcp_connections.c: copy peer_ed25519 from STCP to ETCP_CONN in
  etcp_link_enter_ready_tcp; guard link->etcp in tcp_link_close_cb
- chat_sync.c: fix lk->conn NULL dereference for TCP links
- test_stcp.c: update stcp_server_create/stcp_client_connect callsites
- tools/chat_tcp_test: change transport udp→tcp

evgeny d773f1724a refactor: STCP connections as ETCP links (is_tcp)
- Add is_tcp, tcp_link, tcp_reconnect_* fields to ETCP_LINK
- Remove transport_link from ETCP_CONN, add tcp_link_count
- stcp_link: replace embedded etcp_conn with pointer; add etcp_link backpointer
- stcp_link: link_rx_cb routes ETCP data to etcp_conn_input
- stcp_link: call on_close_cb in close
- New TCP functions: etcp_link_enter_ready_tcp, etcp_tcp_link_start_connect,
  etcp_tcp_link_start_reconnect, tcp_link_close_cb, etcp_tcp_send
- etcp_link_new: handle NULL conn for TCP links; skip enter_init for TCP
- etcp_link_close: close stcp_link for TCP
- etcp_encrypt_send: redirect TCP to etcp_tcp_send (skips AES-CCM)
- tcp_server_on_link: create ETCP_LINK(is_tcp=1) + enter_ready_tcp
- etcp_connect: TCP addrs -> etcp_tcp_link_start_connect
- Remove ctx->tcp_link/tcp_ready
- test_stcp_traffic: find stcp_link via links->is_tcp instead of transport_link
- 66/68 tests pass; 2 STCP tests expected to fail (integration not complete)

evgeny d310bccf08 fix: memory pool alloc mismatch in tests, db_sync SEND_DATA buffer overflow
- test_etcp_router_reconnect, test_etcp_connect, test_stcp_traffic:
  replace u_calloc with memory_pool_alloc for TOPO_SOCKMETA4/TOPO_ADDR4
- db_sync.c: fix req[14] -> req[15] — SEND_DATA request header is 15 bytes
  (type:1 + from:4 + count:2 + vp:4 + want_from:4)

Evgeny fcf3fb7f51 refactor: move transport (etcp/stcp/normalizer) to transport_layer/, routing (bgp/pings/topo*) to routing_layer/ 2026-07-21 20:25:41 +03:00
Evgeny 3c3d9a65d9 refactor: переименование route_node/route_bgp в topo_node/topo_bgp
Файлы: route_node.* route_node_lmdb.* route_bgp.* -> topo_node.* topo_node_lmdb.* topo_bgp.*

Структуры:
- ROUTE_BGP -> TOPO_BGP, ROUTE_BGP_CONN_ITEM -> TOPO_BGP_CONN_ITEM
- NODEINFO -> TOPO_NODE, NODEINFO_Q -> TOPO_NODEQ, NODEINFO_PATH -> TOPO_NODEPATH
- NODEINFO_ROUTES -> TOPO_NODESUBNETS, NODE_CONNECTIVITY -> TOPO_CONNECTIVITY
- wire: NODEINFO_MSG -> TOPOMSG_NODE, NODEINFO_IPV4_* -> TOPOMSG_*4 и т.д.
- memory: NI_IPV4_* -> TOPO_*4, NI_IPV6_* -> TOPO_*6
- ROUTE_SUBCMD_* -> TOPO_SUBCMD_*, ETCP_ID_ROUTE_ENTRY -> ETCP_ID_TOPO_ENTRY

Функции:
- route_bgp_* -> topo_bgp_*
- nodeinfo_* -> topo_node_*
- route_node_* -> topo_node_*
- route_node_lmdb_* -> topo_node_lmdb_*

Смысл: отделение механизма формирования топологии узлов от IP-роутинга.

Evgeny c7ac42eb5f route_node: refactor NODEINFO — separate protocol/memory structs, linked lists with memory_pool
- 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

Evgeny 7d460ca156 fix: ASAN-detected UAFs and buffer overflows across 6 modules
- etcp_connections: fix link leak & UAF in etcp_socket_remove — remove_link inside etcp_link_close shifts array, skip NULL set and i++
- stcp_server: fix UAF in stcp_conn_process_recv — defer free via uasync_call_soon after stcp_conn_do_close
- etcp: save pkt_len before queue_data_put to output_queue (callback may free entry synchronously)
- socks_proxy: add pool bounds check before memcpy, UINT16_MAX truncation guard, freed flag
- tcp_proxy_server: reorder cleanup (cancel waiters before tcp_conn_destroy), UINT16_MAX guard
- test_route6_lib: increase nodes[] array to STRESS_NODES + STRESS_OPS

Evgeny 075d97a459 fix .gitignore: stop ignoring test_*.c source files; add missing test_ipv6_sockets, test_tcp_proxy, test_radix, test_route6_lib sources 2026-05-10 00:34:28 +03:00
