Patch "scsi: qla2xxx: Fix Relogin being triggered too fast" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled scsi: qla2xxx: Fix Relogin being triggered too fast to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: scsi-qla2xxx-fix-relogin-being-triggered-too-fast.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 4005a995668b8fd58f4cf1460dd4cf63efa18363 Mon Sep 17 00:00:00 2001 From: Quinn Tran <quinn.tran(a)cavium.com> Date: Mon, 4 Dec 2017 14:45:06 -0800 Subject: scsi: qla2xxx: Fix Relogin being triggered too fast From: Quinn Tran <quinn.tran(a)cavium.com> commit 4005a995668b8fd58f4cf1460dd4cf63efa18363 upstream. Current driver design schedules relogin process via DPC thread every 1 second. In a large fabric, this DPC thread tries to schedule too many jobs and might get overloaded. As a result of this processing of DPC thread, it can schedule relogin earlier than 1 second.

Patch "scsi: qla2xxx: Fix memory leak in dual/target mode" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled scsi: qla2xxx: Fix memory leak in dual/target mode to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: scsi-qla2xxx-fix-memory-leak-in-dual-target-mode.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 7867b98dceb7741065c9c1b645136facad5c2e93 Mon Sep 17 00:00:00 2001 From: "himanshu.madhani(a)cavium.com" <himanshu.madhani(a)cavium.com> Date: Mon, 4 Dec 2017 14:45:16 -0800 Subject: scsi: qla2xxx: Fix memory leak in dual/target mode From: himanshu.madhani(a)cavium.com <himanshu.madhani(a)cavium.com> commit 7867b98dceb7741065c9c1b645136facad5c2e93 upstream. When driver is loaded in Target/Dual mode, it creates QPair to support MQ and allocates resources for each QPair. This Qpair initialization is delayed until the FW personality is changed to Dual/Target mode by issuing chip reset. At the time of chip reset firmware is re-initilized in correct personality all the QPairs are initialized by sending MBC_INITIALIZE_MULTIQ (001Fh). This patch fixes memory leak by adding check to issue MBC_INITIALIZE_MULTIQ command only while deleting rsp/req queue when the flag is set for initiator mode, and clean up QPair resources correctly during the driver unload. This MBX does not need to be issued for Target/Dual mode because chip reset will reset ISP.
