From c3e51442711d20ea1245bb6d260aa05593849e82 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger Date: Wed, 19 Jun 2013 18:48:51 -0700 Subject: iscsi-target: Add demo-mode TPG authentication context support This patch adds a auth configfs group context following existing explict NodeACL and discovery auth within: /sys/kernel/config/target/iscsi/$TARGETNAME/$TPGT/auth/ This patch allows these attributes to be used for CHAP authentication an TPG is configured in demo-mode (generate_node_acl=1). Note this authentication information takes precedence over NodeACL authentication when struct se_node_acl->dynamic_node_acl is present.
