auto_socket.c: remove tsrv from inst->stcp_servers before stcp_link_server_destroy
when TCP socket has null addr — freed pointer stayed in linked list corrupting it
on next stcp_server_listen->stcp_server_list_add, causing hang
utun_instance.c: apply debug_level + per-category debug from config in
utun_instance_create_from_config (was only in utun_instance_create)
chat_core.c: verbose error log on invalid args
- 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
- etcp_connections.h: add WIRE_OVERHEAD, IP_UDP_OVERHEAD_V4/V6, SC_ENCRYPT_OVERHEAD
(properly accounts for v6 IP(40)+UDP(8)+SC(3)+CCM tag(16) = 67 vs old UDP_HDR_SIZE=28)
- etcp_connections.c etcp_encrypt_send: use WIRE_OVERHEAD instead of UDP_HDR_SIZE
- etcp_connections.c send_init_response: clamp padding to max_data = mtu - WIRE_OVERHEAD
- chat_core_priv.h: add addr_type_from_ip() classifier
- chat_profile.c, chat_sync.c, member_sync.c: use classified addr_type instead of hardcoded 0
- chat_sync.c: skip zero nat_addr in JOIN, fall back to interface_addr
- topo_node_sqlite.c, member_sync.c: remove addr_type=0 filter from SELECT/DELETE
- chat_profile.c, member_sync.c: DELETE all addresses (not just addr_type=0)
- node_put/node_update_verified: set online=1 on INSERT (nodes created when conn is UP)
- channel_peers_all: fix peer_needed calculation (atl byte was missing)
- cs_send_channel_join: add proto byte to address serialization matching all parsers
Root cause: instance_lite_restart was creating new thread without
re-setting g_event_handler, causing all chat events (CHANNEL_UPDATED,
CONNECT_RESULT, etc.) to be silently dropped after app restart.
Fixes:
- instance_lite_restart: save/restore g_event_handler across hard restart
- instance_thread restart loop: re-call chat_event_set_handler after uasync_create
- utun_bridge_restart: call instance_lite_set_event_handler before restart
- AppEventHandler SharedFlow replay: 1 → 16 to not lose early init events
- ViewModel: added diagnostic logging for channel/connect events
- Keep diagnostic logs in instance_lite (set_handler, chat_event_forward NULL check)
- instance_event_handler: removed static for cross-block forward declaration
- member_sync apply_items: empty payload is normal sync completion, not error
- topo_node_sqlite node_load: no addresses is normal for stub/seed nodes
- conn_mgr_core: node skipped when not in routing (normal for nodes w/o addrs)
- topo_group send_nodeinfo: downgrade ERROR→WARN in DEBUG category
- db_sync INIT_RESP: protocol details belong in DEBUG, not INFO
chat_core_attachment_download: use sqlite3_column_text for null-term
on_msg_inserted: copy data to local null-term buf before strstr
Both caused b64_decode to misread body from garbage memory
* prefix prepended in on_media_registered before b64 data
on_msg_inserted, chat_core_attachment_download, get_messages_json
only attempt b64_decode when prefix starts with '*' marker
- _compute_bucket_hash: SELECT protocol, write proto byte
- _member_get_items: SELECT protocol, write proto byte
- _member_apply_items: consume proto byte in skip calculation
- topo_node_sqlite_channel_peers_all: SELECT protocol, write proto byte
All 5 writers and 5 readers now consistently include protocol byte.
- stcp_server_create: support AF_INET and AF_INET6 V6ONLY=1 (no dual-stack)
- Add listen_family to stcp_link_config
- init_sockets: return error (not partial) on any bind failure
- add chat_core_sync_my_addresses() call at chatgui startup
- collect_my_addrs: add proto byte (1=UDP, 2=TCP) to binary format
- chat_sync.c JOIN/WELCOME/PEER_UPSERT: read proto byte, write protocol column
- member_sync.c: read proto byte, dynamic protocol bind
- topo_node.c: debug logs for nodeinfo changed detection
- node_config.cpp: type=public for all servers
- Replace instance->stcp_server (single pointer) with stcp_servers linked list
- Add stcp_server_list_add/destroy_all/count API in stcp_link.h/c
- Fix port extraction for both AF_INET and AF_INET6 in init_sockets
- Filter out 0.0.0.0 and [::] addresses in chat_profile.c TCP address sync
- Add type=public to servers in node_config.cpp saveFull()
Remote peers should not overwrite local node_addresses.
When member_sync_recv processes data about our own node_id,
we trust locally-synced addresses (from sync_my_addresses)
and ignore address data from the remote peer.
sync_my_addresses used interface_addr even when its family
differed from the socket's local_addr family. A v4 socket
bound to 0.0.0.0 could pick up a v6 interface_addr on
dual-stack Android, inserting a duplicate v6 entry.
Now interface_addr is only used when families match.
Android chatgui:
- New MemberListScreen with member list, detail card, edit dialog
- Link status dots (green/red/grey) per address in detail card (1s poll)
- Self-node name coloured green
- ChatScreen: people icon in TopAppBar
IPv6 autoconnect fixes (3 bugs in conn_mgr/topo):
- topo_node_sqlite_node_load: load v6 addresses from DB
- topo_node_registry_store: merge v6_addrs into existing node
- cm_sock_v6_classify: wildcard [::] treated as CM_V6_DIR
- cm_add_v6_link: htons(port) was missing
Memory fixes:
- strdup→u_strdup in bridge (7 instances)
- u_realloc cap update before success check (3 instances)
- char sql[256]→[512] for truncated SELECT
Chat member hash now includes addresses for change detection
Linux chatgui:
- Link status dots in AccountList detail panel (1s poll)
- Self-node name in green in member list
- db_record_insert_cascade: unified insert with on_insert + PUSH cascade
- SYNC_DONE moved from INIT_RESP to DATA handler (master sends after slave response)
- db_sync_add/remove_done_cbk: global sync-completion subscription (etcp pattern)
- REQUEST_SYNC handler: sync_state != 1 instead of == 0
- SYNC_DONE mc==pc hash mismatch: accept as converged
- Removed unconditional sync_state=2 from DATA handler
- test: done_cbk for sync phases, count-only for PUSH phases, removed dead B<>C reinitiate
g_cc.db_path is '/data/.../files/chats.db' (file path), but media blocks
are written to '/data/.../files/media/<channel>/'. chat_msg was concatenating
'chats.db/media/...' — now strips the database filename, using only the
directory portion for the media path.
- instance_lite: cleanup moved to uasync thread (self-detach), events on start/stop
- udp_log: cancel_timer before uasync_destroy, flush on stop, stopping flag
- jni_bridge: fixed UDP stop order (cancel_timer → destroy → flush)
- instance_lite: u_report_unfreed_blocks at all shutdown paths
- chat_event: CHAT_EVT_SERVICE_STARTED/STOPPED for GUI notifications
- AGENTS: logreceiver section
