evgeny 90d3206071 Confirm new TCP sessions and bound reciprocal challenge retries 
Negotiate new TCP sessions even when the peer epoch is known, and let the retry timer send reciprocal challenges to avoid feedback loops when confirmations are lost.

Cover peer restarts, simultaneous connects, REALITY, confirmation loss, second links, stale confirmations and deadlines. Remove forced client resets and count only validated test payloads in the UDP reconnect test.

Validation: 149 tests passed; proxy, burst and load integration tests passed; Android assembleDebug succeeded.

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 a3783b5f55 fix: re-index conn_queue_entry after setting peer_node_id 
tcp_server_on_link sets conn->peer_node_id after etcp_connection_create
which adds the entry with peer_node_id=0. instance_find_conn couldnt
find TCP connections until the queue entry was re-indexed.

evgeny adac854c94 fix: TCP data flow — tx_state, keepalive, last_recv_local_time 
- etcp_link_enter_ready_tcp: set tx_state=DATA_WAIT (was 0, blocking sends)
- etcp_conn_input: update last_recv_local_time on every packet (keepalive liveness)
- link_rx_cb: handle ETCP_KEEPALIVE before etcp_conn_input (conflicts with MEAS_RESP=0x08)
- KEEPALIVE handler: set recv_keepalive, remote_keepalive, link_status, keepalive_recv_count
- test_stcp_traffic: etcp_send instead of raw stcp_link_send
- test_etcp_stcp: rewrite for utun_instance + etcp_connect

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 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 2bbdf8195f fix: TASSERT return value in test_etcp_stcp.c and test_stcp_link.c 2026-06-18 22:11:25 +03:00
Evgeny 150e9977df stcp: unified transport — etcp_send/bind over TCP via stcp_link 
- stcp_link.h/c: manage TCP connections through STCP protocol
  stcp_server_listen, stcp_link_connect/send/close
  rx dispatch goes directly through inst->api_bindings (single table)
- etcp_api.c: etcp_send checks conn->transport_link for TCP path
  etcp_bind stores only in api_bindings (no duplication)
- etcp_connections.c: init_sockets creates stcp_server for TCP
  init_connections creates stcp_link_connect for TCP clients
  tcp_server_on_link creates minimal ETCP_CONN + fires callbacks
- etcp.h: ETCP_CONN.transport_link field (NULL for UDP, set for TCP)
- config_parser: CFG_SERVER.transport field, parsing transport=tcp|udp
- utun_instance.h: struct stcp_server*
- Tests: test_stcp_link (handshake, wrong key)
         test_etcp_stcp (etcp_send/bind over TCP)
- Renamed: transport.h/c → stcp_link.h/c (cleaner, no bindings table)
- 46/46 tests pass
