From ba159914086f06532079fc15141f46ffe7e04a41 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Wed, 3 Jul 2013 03:48:24 -0700 Subject: iscsi-target: Fix iscsit_add_reject* usage for iser This patch changes iscsit_add_reject() + iscsit_add_reject_from_cmd() usage to not sleep on iscsi_cmd->reject_comp to address a free-after-use usage bug in v3.10 with iser-target code. It saves ->reject_reason for use within iscsit_build_reject() so the correct value for both transport cases. It also drops the legacy fail_conn parameter usage throughput iscsi-target code and adds two iscsit_add_reject_cmd() and iscsit_reject_cmd helper functions, along with various small cleanups. (v2: Re-enable target_put_sess_cmd() to be called from iscsit_add_reject_from_cmd() for rejects invoked after target_get_sess_cmd() has been called) Cc: Or Gerlitz Cc: Mike Christie Cc: stable@vger.kernel.org # 3.10+ Signed-off-by: Nicholas Bellinger --- drivers/target/iscsi/iscsi_target_util.c | 1 - 1 file changed, 1 deletion(-) (limited to 'drivers/target/iscsi/iscsi_target_util.c') diff --git a/drivers/target/iscsi/iscsi_target_util.c b/drivers/target/iscsi/iscsi_target_util.c index fe712d6cc478..96ce6f2ec428 100644 --- a/drivers/target/iscsi/iscsi_target_util.c +++ b/drivers/target/iscsi/iscsi_target_util.c @@ -178,7 +178,6 @@ struct iscsi_cmd *iscsit_allocate_cmd(struct iscsi_conn *conn, gfp_t gfp_mask) INIT_LIST_HEAD(&cmd->i_conn_node); INIT_LIST_HEAD(&cmd->datain_list); INIT_LIST_HEAD(&cmd->cmd_r2t_list); - init_completion(&cmd->reject_comp); spin_lock_init(&cmd->datain_lock); spin_lock_init(&cmd->dataout_timeout_lock); spin_lock_init(&cmd->istate_lock); -- cgit v1.2.3
