[Linux-stable-mirror] [merged] ocfs2-fix-cluster-hang-after-a-node-dies.patch removed from -mm tree

by akpm＠linux-foundation.org

The patch titled Subject: ocfs2: fix cluster hang after a node dies has been removed from the -mm tree. Its filename was ocfs2-fix-cluster-hang-after-a-node-dies.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Changwei Ge <ge.changwei(a)h3c.com> Subject: ocfs2: fix cluster hang after a node dies When a node dies, other live nodes have to choose a new master for an existed lock resource mastered by the dead node. As for ocfs2/dlm implementation, this is done by function - dlm_move_lockres_to_recovery_list which marks those lock rsources as DLM_LOCK_RES_RECOVERING and manages them via a list from which DLM changes lock resource's master later. So without invoking dlm_move_lockres_to_recovery_list, no master will be choosed after dlm recovery accomplishment since no lock resource can be found through ::resource list. What's worse is that if DLM_LOCK_RES_RECOVERING is not marked for lock resources mastered a dead node, it will break up synchronization among nodes. So invoke dlm_move_lockres_to_recovery_list again. Fixs: 'commit ee8f7fcbe638 ("ocfs2/dlm: continue to purge recovery lockres when recovery master goes down")' Link: http://lkml.kernel.org/r/63ADC13FD55D6546B7DECE290D39E373CED6E0F9@H3CMLB14-… Signed-off-by: Changwei Ge <ge.changwei(a)h3c.com> Reported-by: Vitaly Mayatskih <v.mayatskih(a)gmail.com> Tested-by: Vitaly Mayatskikh <v.mayatskih(a)gmail.com> Cc: Mark Fasheh <mfasheh(a)versity.com> Cc: Joel Becker <jlbec(a)evilplan.org> Cc: Junxiao Bi <junxiao.bi(a)oracle.com> Cc: Joseph Qi <jiangqi903(a)gmail.com> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> --- fs/ocfs2/dlm/dlmrecovery.c | 1 + 1 file changed, 1 insertion(+) diff -puN fs/ocfs2/dlm/dlmrecovery.c~ocfs2-fix-cluster-hang-after-a-node-dies fs/ocfs2/dlm/dlmrecovery.c --- a/fs/ocfs2/dlm/dlmrecovery.c~ocfs2-fix-cluster-hang-after-a-node-dies +++ a/fs/ocfs2/dlm/dlmrecovery.c @@ -2419,6 +2419,7 @@ static void dlm_do_local_recovery_cleanu dlm_lockres_put(res); continue; } + dlm_move_lockres_to_recovery_list(dlm, res); } else if (res->owner == dlm->node_num) { dlm_free_dead_locks(dlm, res, dead_node); __dlm_lockres_calc_usage(dlm, res); _ Patches currently in -mm which might be from ge.changwei(a)h3c.com are

[Linux-stable-mirror] [PATCH 1/2] ASoC: da7218: fix fix child-node lookup

by Johan Hovold

Fix child-node lookup during probe, which ended up searching the whole device tree depth-first starting at the parent rather than just matching on its children.

[Linux-stable-mirror] dmaengine: dmatest: warn user when dma test times out

by Adam Wallis

a9df21e34b42 ("dmaengine: dmatest: warn user when dma test times out") for 4.14-stable (applies cleanly) for 4.13-stable (applies cleanly) This should be included since it warns the user that the kernel stack memory may have been corrupted due to a fault DMA callback. I could also backport for older 4.x kernels if you think it would be useful. -- Adam Wallis Qualcomm Datacenter Technologies as an affiliate of Qualcomm Technologies, Inc.

Hi Greg, as promised a month ago, here finally come the tested backports of this fix for 4.9 and 4.4 respectively. This backport is not needed for 3.18 as the regression was introduced in 3.19-rc1. Cheers, Willy

[Linux-stable-mirror] [PATCH] bcache: Fix building error on MIPS

This patch try to fix the building error on MIPS. The reason is MIPS has already defined the PTR macro, which conflicts with the PTR macro in include/uapi/linux/bcache.h.

[Linux-stable-mirror] Patch "target/iscsi: Fix iSCSI task reassignment handling" has been added to the 4.9-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled target/iscsi: Fix iSCSI task reassignment handling to the 4.9-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: target-iscsi-fix-iscsi-task-reassignment-handling.patch and it can be found in the queue-4.9 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 59b6986dbfcdab96a971f9663221849de79a7556 Mon Sep 17 00:00:00 2001 From: Bart Van Assche <bart.vanassche(a)sandisk.com> Date: Thu, 5 Jan 2017 12:39:57 +0100 Subject: target/iscsi: Fix iSCSI task reassignment handling From: Bart Van Assche <bart.vanassche(a)sandisk.com> commit 59b6986dbfcdab96a971f9663221849de79a7556 upstream. Allocate a task management request structure for all task management requests, including task reassignment. This change avoids that the se_tmr->response assignment dereferences an uninitialized se_tmr pointer.
