Author	SHA1	Message	Date
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	3 months ago
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	3 months ago
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	3 months ago
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.	3 months ago
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	3 months ago
