[Linux-stable-mirror] [PATCH] cxl: Check if vphb exists before iterating over AFU devices

by Vaibhav Jain

commit 12841f87b7a8ceb3d54f171660f72a86941bfcb3 upstream, for 4.3. During an eeh a kernel-oops is reported if no vPHB is allocated to the AFU. This happens as during AFU init, an error in creation of vPHB is a non-fatal error. Hence afu->phb should always be checked for NULL before iterating over it for the virtual AFU pci devices. This patch fixes the kenel-oops by adding a NULL pointer check for afu->phb before it is dereferenced.

[Linux-stable-mirror] [PATCH V2] block-throttle: avoid double charge

by Shaohua Li

If a bio is throttled and splitted after throttling, the bio could be resubmited and enters the throttling again. This will cause part of the bio is charged multiple times. If the cgroup has an IO limit, the double charge will significantly harm the performance. The bio split becomes quite common after arbitrary bio size change. To fix this, we always set the BIO_THROTTLED flag if a bio is throttled. If the bio is cloned/slitted, we copy the flag to new bio too to avoid double charge. However cloned bio could be directed to a new disk, keeping the flag will have problem. The observation is we always set new disk for the bio in this case, so we can clear the flag in bio_set_dev(). This issue exists a long time, arbitrary bio size change makes it worse, so this should go into stable at least since v4.2.

[Linux-stable-mirror] Patch "cxl: Check if vphb exists before iterating over AFU devices" 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 cxl: Check if vphb exists before iterating over AFU devices 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: cxl-check-if-vphb-exists-before-iterating-over-afu-devices.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 12841f87b7a8ceb3d54f171660f72a86941bfcb3 Mon Sep 17 00:00:00 2001 From: Vaibhav Jain <vaibhav(a)linux.vnet.ibm.com> Date: Thu, 23 Nov 2017 09:08:57 +0530 Subject: cxl: Check if vphb exists before iterating over AFU devices From: Vaibhav Jain <vaibhav(a)linux.vnet.ibm.com> commit 12841f87b7a8ceb3d54f171660f72a86941bfcb3 upstream. During an eeh a kernel-oops is reported if no vPHB is allocated to the AFU. This happens as during AFU init, an error in creation of vPHB is a non-fatal error. Hence afu->phb should always be checked for NULL before iterating over it for the virtual AFU pci devices. This patch fixes the kenel-oops by adding a NULL pointer check for afu->phb before it is dereferenced.
