From ba7736696341ad4253125055c0c85aa9f42959a0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Sat, 13 Aug 2011 22:35:00 -0700 Subject: iscsi-target: Fix iscsit_allocate_se_cmd_for_tmr failure path bugs This patch fixes two bugs in allocation failure handling in iscsit_allocate_se_cmd_for_tmr(): This first reported by DanC is a free-after call to transport_free_se_cmd(), this patch drops the transport_free_se_cmd() call all together, as iscsit_release_cmd() will release existing allocations as expected. The second is a bug where iscsi_cmd_t was being leaked on a cmd->tmr_req allocation failure, so make this jump to iscsit_release_cmd() as well.
