evgeny ce5a84da24 fix: uasync epoll event ordering + test_uasync_socket_race fix 2026-07-29 11:10:55 +03:00
Evgeny bfa3e666d4 fix test_uasync_socket_race: increase listen() backlog from 32 to 1024 
Root cause: accept queue overflow (backlog=32) caused kernel SYN drops.
Children waited ~1s for SYN retransmit timeout (5 gaps × 1s = 5s out of 7.2s).
With backlog=1024 the timeout drops from ~7.2s to ~0.065s (110× faster).

Evgeny 3d04c37f56 stcp: add on_close callback to stcp_server_create/stcp_client_connect; member_sync: add join_ts/update_sig/update_ts fields, verify update_sig in apply; topo_node_sqlite: add join_ts/update_sig/update_ts to member_put, add member_get_join, add node_update_verified; chat_sync: include join_ts in join_msg, add update_sig/update_ts to CHANNEL_INFO_RESP; WELCOME verify join_sig; tests: use generated node_ids, reduce max ticks 2026-07-16 19:04:00 +03:00
jeka 7139969acd fix: Windows/MSYS2 build compatibility 
- proxy/icmp_proxy.c: define struct icmp/ip + ICMP constants for _WIN32
- lwip_tcp_priv.h: use #include <winsock2.h> instead of #define htonl/htons
- lwip_tcp.h/c: rename poll field to pollfn (avoid WSAPoll macro conflict)
- tests: guard Unix-only headers with #ifndef _WIN32, skip fork/socketpair tests

Evgeny f06ebd2ab4 fix: protect fd 0 from close in socket_close_wrapper + dup2 reserve in tests 
- socket_close_wrapper: never close sock==0 (prevents fd 0 reuse cycle)
- test_uasync_socket_race: dup2-based fd 0 reservation, pass 800/800
- tcp_io: SOCKET_INVALID before on_error (previous commit)
- Plus earlier fixes: uasync gen counter, ll_queue call_soon_id, pkt_normalizer

Result: test_uasync_socket_race PASSES, 50/51 tests pass

Evgeny a97a38d867 fix: set tc->sock=SOCKET_INVALID before on_error in handle_error 
В одном epoll_wait batch три события для fd: EPOLLERR (освобождает tc),
EPOLLIN (read_cb), EPOLLOUT (write_cb). read_cb/write_cb guard проверяет
tc->sock==SOCKET_INVALID, но sock обнулялся ПОСЛЕ on_error.
Перенос sock=SOCKET_INVALID до on_error защищает от use-after-free.

Доказано: без фикса segfault на tcp_io.c:374 (write_cb → tc->connected).
С фиксом тест работает без крашей.

Evgeny ccdbab95a8 fix: use-after-free in pkt_normalizer + ll_queue waiter cancel + uasync gen counter for epoll fd-reuse 
- pkt_normalizer: save recvpart->len before queue_data_put (may free synchronously)
- ll_queue: save uasync_call_soon handle in queue_waiter_handle, cancel on free
- uasync: generation counter in epoll data.u64 to skip stale events after fd reuse
- uasync: keep fd_to_index mapping after socket_array_remove for inactive nodes
- test: test_uasync_socket_race — 4 children × 200 iterations, currently flaky
