From cd931ee62fd0258fc85c76a7c5499fe85e0f3436 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Mon, 16 Jan 2012 17:11:54 -0800 Subject: iscsi-target: Fix double list_add with iscsit_alloc_buffs reject This patch fixes a bug where the iscsit_add_reject_from_cmd() call from a failure to iscsit_alloc_buffs() was incorrectly passing add_to_conn=1 and causing a double list_add after iscsi_cmd->i_list had already been added in iscsit_handle_scsi_cmd().

To address this, save local socket ->getname() output during iscsi login setup, and makes iscsit_build_sendtargets_response() return these TargetAddress keys when INADDR_ANY or IN6ADDR_ANY_INIT portals are in use.
