This is a note to let you know that I have just added a patch titled iscsi-target: Add explicit set of cache_dynamic_acls=1 for to the linux-3.5.y-queue branch of the 3.5.yuz extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.yuz tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Herton ------ From f4bb5366731db01ada3a1c35cd5917cf22fb54a1 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger <nab@linux-iscsi.org> Date: Sun, 30 Sep 2012 12:20:02 -0700 Subject: [PATCH] iscsi-target: Add explicit set of cache_dynamic_acls=1 for TPG demo-mode commit 38b11bae6ba02da352340aff12ee25755977b222 upstream. We've had reports in the past about this specific case, so it's time to go ahead and explicitly set cache_dynamic_acls=1 for generate_node_acls=1 (TPG demo-mode) operation. During normal generate_node_acls=0 operation with explicit NodeACLs -> se_node_acl memory is persistent to the configfs group located at /sys/kernel/config/target/$TARGETNAME/$TPGT/acls/$INITIATORNAME, so in the generate_node_acls=1 case we want the reservation logic to reference existing per initiator IQN se_node_acl memory (not to generate a new se_node_acl), so go ahead and always set cache_dynamic_acls=1 when TPG demo-mode is enabled.
