From 7a882133b181058ba7851e302ec218a896695c55 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 19 Mar 2015 22:25:16 -0700 Subject: [PATCH] tcm_qla2xxx: Fix incorrect use of __transport_register_session commit 75c3d0bf9caebb502e96683b2bc37f9692437e68 upstream. This patch fixes the incorrect use of __transport_register_session() in tcm_qla2xxx_check_initiator_node_acl() code, that does not perform explicit se_tpg->session_lock when accessing se_tpg->tpg_sess_list to add new se_sess nodes. Given that tcm_qla2xxx_check_initiator_node_acl() is not called with qla_hw->hardware_lock held for all accesses of ->tpg_sess_list, the code should be using transport_register_session() instead.
