From: Nicholas Bellinger <[email protected]> This patch addresses a case where iscsi_target_do_tx_login_io() fails sending the last login response PDU, after the RX/TX threads have already been started. The case centers around iscsi_target_rx_thread() not invoking allow_signal(SIGINT) before the send_sig(SIGINT, ...) occurs from the failure path, resulting in RX thread hanging indefinately on iscsi_conn->rx_login_comp. Note this bug is a regression introduced by: commit e54198657b65625085834847ab6271087323ffea Author: Nicholas Bellinger <[email protected]> Date: Wed Jul 22 23:14:19 2015 -0700 iscsi-target: Fix iscsit_start_kthreads failure OOPs To address this bug, complete ->rx_login_complete for good measure in the failure path, and immediately return from RX thread context if connection state did not actually reach full feature phase (TARG_CONN_STATE_LOGGED_IN).
Hey Nic, Will it make better sense to start the rx/tx threads after the login was completed (i.e. the conn is in state TARG_CONN_STATE_LOGGED_IN) instead?
