- etcp_conn_reset: queue_resume_callback after clear_queue (input_queue,
input_send_q, input_wait_ack) to prevent suspended callback deadlock
- is_connection_established: check conn->initialized (reliable across
reinit) instead of link->initialized (never cleared on reinit)
- test: force etcp_conn_reinit after server recreation so conn_ok
waits for fresh INIT handshake
- test: guard send_packets() with is_connection_established in reconnect
phases to avoid sending data while conn is down
- etcp_link_update_inflight_lim: self-contained method with clamping,
send_blocked_inflight check, loadbalancer_link_ready on cwnd increase
- etcp_conn_on_inflight_lim_changed: recalc optimal_inflight + resume input
- etcp_ack_recv: use etcp_link_update_inflight_lim instead of manual set
- etcp_request_pkt: fix line 928 check old link (inf_pkt->last_link) not new
- etcp_link_close: recalc optimal_inflight on link removal (both branches)
- etcp_socket_remove: fix dangling pointer loop (nullify after close)
- uasync_print_resources: show timer names, remain time, deleted entries
- diagnostics in utun_instance_destroy and test_etcp_reconnect
- etcp_conn_reset: cancel retrans_timer/ack_resp_timer via uasync_cancel_timeout
before nulling (was leaking timer handles, confirmed by 'Timer leak: diff')
- etcp_connections: cancel link->init_timer explicitly when link_state becomes 3
on both client and server INIT_RESPONSE paths (prevents spurious INIT after
connection is established that could trigger cascading reinits)
- etcp_connections: remove duplicate conn->session_id assignment in new conn path
(session_id is set later via conn_reinit flow)
- pkt_normalizer: resume output queue callback after pn_reset
- Add test_etcp_reconnect with reinit detection — monitors conn->reinit_count
and restarts data transfer if reinit occurs during active phase
- Add etcp_dump.c/h — ETCP connection state dump utility for debugging
