From 683497566d48f86e04d026de1ee658dd74fc1077 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Tue, 17 Jun 2014 21:54:38 +0000 Subject: iscsi-target: Explicily clear login response PDU in exception path This patch adds a explicit memset to the login response PDU exception path in iscsit_tx_login_rsp(). This addresses a regression bug introduced in commit baa4d64b where the initiator would end up not receiving the login response and associated status class + detail, before closing the login connection.
