This is a note to let you know that I have just added a patch titled target: Re-add explict zeroing of INQUIRY bounce buffer 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 0d32695d8203dad57dcbdc2d7cb91a99b2725185 Mon Sep 17 00:00:00 2001 From: Nicholas Bellinger <nab@linux-iscsi.org> Date: Wed, 31 Oct 2012 22:04:26 -0700 Subject: [PATCH 1/5] target: Re-add explict zeroing of INQUIRY bounce buffer memory commit dea5f0998aa82bdeca260b87c653db11e91329b2 upstream. This patch fixes a regression in spc_emulate_inquiry() code where the local scope bounce buffer was no longer getting it's memory zeroed, causing various problems with SCSI initiators that depend upon areas of INQUIRY EVPD=0x83 payload having been zeroed. This bug was introduced with the following v3.7-rc1 patch + CC'ed stable commit: commit ffe7b0e9326d9c68f5688bef691dd49f1e0d3651 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Fri Sep 7 17:30:38 2012 +0200 target: support zero allocation length in INQUIRY Go ahead and re-add the missing memset of bounce buffer memory to be copied into the outgoing se_cmd descriptor kmapped SGL payload.
