If anyone has any objections, please let me know. ------------------ From: Nicholas Bellinger commit 683497566d48f86e04d026de1ee658dd74fc1077 upstream. 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.
