Set secondary_socket_id = NX_BSD_MAX_SOCKETS to invalidate the slot for future accept() calls, but still return the already-accepted FD. - Restore select() writefds 'not in use' case: closed/unallocated descriptors must be reported immediately as writable per BSD semantics. Several tests (netx_bsd_tcp_basic_blocking_test, _rcvbuf_test, _getaddrinfo_test) depend on this behaviour. - Fix select() exceptfds race with readfds: the readfds scan calls nx_tcp_socket_receive() which dequeues the head packet; a subsequent peek at nx_tcp_socket_receive_queue_head in the exceptfds scan then finds NULL. Move the URG/push-flag check into the readfds scan immediately after the successful dequeue while the packet is still accessible. - Add regression test netx_bsd_select_improvements_test covering: * zero-timeout select clears all fdsets without blocking * normal TCP data sets readfds, not exceptfds * a not-in-use descriptor appears in writefds Register test in regression/CMakeLists.txt. --------- Co-authored-by: Frédéric Desbiens <frederic.desbiens@eclipse-foundation.org> Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
