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.

Original code acquires hardware_lock to add Abort IOCB onto driver request queue for processing. However, abort_command() will also acquire hardware lock to look up sp pointer before issuing abort IOCB command resulting into a deadlock. This patch safely removes the possible deadlock scenario by removing extra spinlock. Fixes: 6eb54715b54bb ("qla2xxx: Added interface to send explicit LOGO.")

Patch "NFS: Fix unstable write completion" has been added to the 4.15-stable tree

This is a note to let you know that I've just added the patch titled NFS: Fix unstable write completion 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: nfs-fix-unstable-write-completion.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 c4f24df942a181699c5bab01b8e5e82b925f77f3 Mon Sep 17 00:00:00 2001 From: Trond Myklebust <trond.myklebust(a)primarydata.com> Date: Wed, 7 Mar 2018 15:22:31 -0500 Subject: NFS: Fix unstable write completion From: Trond Myklebust <trond.myklebust(a)primarydata.com> commit c4f24df942a181699c5bab01b8e5e82b925f77f3 upstream. We do want to respect the FLUSH_SYNC argument to nfs_commit_inode() to ensure that all outstanding COMMIT requests to the inode in question are complete. Currently we may exit early from both nfs_commit_inode() and nfs_write_inode() even if there are COMMIT requests in flight, or unstable writes on the commit list. In order to get the right semantics w.r.t. sync_inode(), we don't need to have nfs_commit_inode() reset the inode dirty flags when called from nfs_wb_page() and/or nfs_wb_all(). We just need to ensure that nfs_write_inode() leaves them in the right state if there are outstanding commits, or stable pages.

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.
