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 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 a7ecee01f5 etcp: replace connections linked-list with indexed ll_queue, add state/ref_count lifecycle
- Remove ETCP_CONN.next linked-list, UTUN_INSTANCE.connections list/count
- Unified connections in single ll_queue indexed by peer_node_id (0=pending)
- struct conn_queue_entry { peer_node_id, conn* } for uniform queue data
- Connection lifecycle via etcp.c: create→pending, conn_ready→indexed, close→detach+deferred free
- Close split: phase1 detach from external world, phase2 deferred via uasync_call_soon
- etcp_conn_set_peer_node_id: reindex on ID change (WARN)
- etcp_conn_ref_take/free: blocking close until refcount returns to 0
- Remove chat_connections — use unified connections queue directly
- Update all iteration/search patterns across 40 files (src + tests + chatgui)

Evgeny 73f707ef9b crypto: migrate ECDH(secp256r1) to X25519, drop TinyCrypt
- SC_PUBKEY_SIZE: 64 -> 32 bytes, SC_PUBKEY_ENC_SIZE: 72 -> 40
- sc_set_peer_public_key uses EVP_PKEY_derive with X25519
- sc_generate_keypair via EVP_PKEY_keygen(EVP_PKEY_X25519)
- sc_compute_public_key_from_private via EVP_PKEY_new_raw_private_key
- sc_validate_key: check non-zero (X25519 has no invalid keys)
- sc_obfuscate_pubkey: XOR now 32 bytes
- Remove all TinyCrypt code (~860 lines), always use OpenSSL
- Remove TinyCrypt from build system, drop test_crypto/test_ecc_encrypt
- Update all test keys (128 hex -> 64 hex)
- Fix bbr_integration.c split-line pubkeys
2026-06-17 21:28:07 +03:00
Evgeny e39979bfac Config: Added [allowed_keys] section for client public key authorization on server
- Added CFG_ALLOWED_KEY struct with binary key storage (64 bytes) for fast memcmp comparison
- Implemented parsing of [allowed_keys] section with allow_all flag and per-key entries
- Added key validation in etcp_connections.c server handler (errorcode=8 for rejected keys)
- Default behavior: deny all if [allowed_keys] section is missing or allow_all=0 with no keys
- Added proper memory cleanup and debug logging for allowed_keys configuration
- Updated all test configs to include [allowed_keys] allow_all=1 for backward compatibility

Evgeny f5faa7c834 Fix Windows build: add default_CSPRNG and improve build.sh error handling
- Add Windows implementation of default_CSPRNG() using CryptGenRandom
- Add fallback stub for platforms without CSPRNG support
- Fix build.sh to properly detect build failures (use PIPESTATUS)
- Show proper error message instead of "Build completed successfully" on failure
2026-02-15 04:34:05 +03:00
Evgeny 4d486c7017 Fix test files for Windows cross-platform compatibility
- Create test_utils.h with cross-platform utility functions:
  * test_mkdtemp() - Windows uses GetTempPath + _mkdir, Linux uses mkdtemp
  * test_unlink() - Windows _unlink, Linux unlink
  * test_rmdir() - Windows _rmdir, Linux rmdir

- Update all test files to use test_utils.h
- Replace arpa/inet.h and netinet/in.h with platform_compat.h
- Replace unistd.h with conditional includes
- Replace mkdtemp(), unlink(), rmdir() with test_* versions

- Tests now build on both Linux and Windows
- Note: Some integration tests may fail on Linux due to test environment

Evgeny 277ab872bf Fix: routing initialization timing and test callbacks
- Fixed race condition: routing_add_conn called before etcp->normalizer was assigned

- Moved routing_add_conn from pn_init to etcp_connection_create after normalizer init

- Added routing.h include to etcp.c

- Fixed tests: disable routing callback on output_queue to keep packets for test verification

All 19 tests now pass.

- Added explicit uasync_destroy calls in all tests and main program

Evgeny 8f60e6092a Fix ETCP input_queue processing and add 100 packets test
- etcp.c: Added queue_resume_callback(q) in input_queue_cb to process all packets
  from input_queue, not just the first one. This fixes packet loss when multiple
  packets are queued.
- Added test_etcp_100_packets.c: Test that sends 100 packets with flow control
  (max 5 packets in queue) to verify queue processing works correctly.
