Alexey Kodanev c277f3420a dccp: don't restart ccid2_hc_tx_rto_expire() if sk in closed state ... [ Upstream commit dd5684ecae ] ccid2_hc_tx_rto_expire() timer callback always restarts the timer again and can run indefinitely (unless it is stopped outside), and after commit 120e9dabaf ("dccp: defer ccid_hc_tx_delete() at dismantle time"), which moved ccid_hc_tx_delete() (also includes sk_stop_timer()) from dccp_destroy_sock() to sk_destruct(), this started to happen quite often. The timer prevents releasing the socket, as a result, sk_destruct() won't be called. Found with LTP/dccp_ipsec tests running on the bonding device, which later couldn't be unloaded after the tests were completed: unregister_netdevice: waiting for bond0 to become free.
