- android_jni_bridge: utun_bridge_set_debug_level actually calls debug_set_level / debug_set_category_level_by_name (was stub)
- SettingsScreen: CATEGORIES updated to match current g_debug_categories from debug_config.c
- ConfigProvider: persist category levels in [debug] section of generated INI config
- u_async: poll() log uses computed timeout_ms instead of confusing %d.%dms format
- u_async: timeout_node char name[16] → const char* name (no truncation, smaller struct)
- memory_pool: pool alloc/free debug logs moved from DEBUG to TRACE
- instance_lite: poll timeout changed from 10ms (100tb) to infinite (-1) — sleeps until traffic
- instance_lite: removed useless heartbeat timer
- 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
memory_pool: memory_pool_is_freed(pool,obj) — поиск obj в free-списке
tw_pcbs (3 места): !ctx→halt и is_freed→halt в начале итерации
— ловит висячий PCB до re-alloc и после re-alloc
etcp: is_freed→halt перед etcp_conn_input (caller + callee)
— ловит pkt освобождённый до входа
tcp_alloc: убран старый скан tw_pcbs (заменён на is_freed)
все dangling проверки — halt (while(1)) вместо break/return
memory_pool: +2 байта за объектом — canary 0xAA для детекции buffer overflow,
counter для детекции double-free. При free проверяется canary и counter==0,
при alloc выставляется новый counter.
lwip_tcp: убраны TCP_TW_MAX и счётчики tw_iter (толку нет, краш на 2й итерации).
Оставлены: !pcb->ctx (dangling pointer), self-loop checks, next_owner диагностика.
Добавлена проверка в tcp_alloc: если новый PCB найден в tw_pcbs → halt.
- Add timeout_heap_get_size() to get active timer count
- Add global counters in memory_pool: g_total_free and g_total_allocated
- Simplify busy memory calculation to single formula:
busy = memory_pool_get_total_allocated() - memory_pool_get_total_free_blocks()
- Add new IDC_EDIT_ACTIVE_TIMEOUTS and IDC_EDIT_BUSY_MEMORY to GUI
