From d06283341aee9e48eff1b068779d340785c635ce Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Sun, 26 Feb 2012 22:16:07 -0800 Subject: [PATCH] iscsi-target: Fix dynamic -> explict NodeACL pointer reference This patch fixes a free after use in lio_target_make_nodeacl() where iscsi_node_acl was referenced from the original se_nacl_new allocation, instead of from core_tpg_add_initiator_node_acl() in the case of dynamic -> explict NodeACL conversion.
