[Backport request] blkdev_report_zones_ioctl(): Use vmalloc() to allocate large buffers

by Bart Van Assche

Hello stable kernel maintainers, Please backport patch 327ea4adcfa3 ("blkdev_report_zones_ioctl(): Use vmalloc() to allocate large buffers") to at least the v4.17.x and v4.14.y stable kernel series. That patch fixes a bug introduced in kernel v4.10. The entire patch is shown below.

Backport bonding patches to fix active-passive in 4.9

by Nate Clark

Hi, On the latest 4.9 stable active-passive bonding does not always failover to the passive slave when carrier is lost on the active slave. It seems that the issue stems from the backport of c4adfc822bf5d8e97660b6114b5a8892530ce8cb, bonding: make speed, duplex setting consistent with link state. There were subsequent patches which resolved issues with the change to bond_update_speed_duplex which were not backported. The three commits which seem to resolve the issue are b5bf0f5b16b9c316c34df9f31d4be8729eb86845, 3f3c278c94dd994fe0d9f21679ae19b9c0a55292 and ad729bc9acfb7c47112964b4877ef5404578ed13. There are other commits in mainline which also revolve around c4adfc822bf5d8e97660b6114b5a8892530ce8cb but are not necessary to resolving the active-passive failover problems. Would it be possible to queue up the three commits for backporting to 4.9 stable: b5bf0f5b16b9c316c34df9f31d4be8729eb86845 bonding: correctly update link status during mii-commit 3f3c278c94dd994fe0d9f21679ae19b9c0a55292 bonding: fix active-backup transition ad729bc9acfb7c47112964b4877ef5404578ed13 bonding: require speed/duplex only for 802.3ad, alb and tlb All of those commits apply cleanly to 4.9.107. Thanks, -nate

[PATCH v2 4/7] vmw_balloon: fix VMCI use when balloon built into kernel

by Nadav Amit

Currently, when all modules, including VMCI and VMware balloon are built into the kernel, the initialization of the balloon happens before the VMCI is probed. As a result, the balloon fails to initialize the VMCI doorbell, which it uses to get asynchronous requests for balloon size changes. The problem can be seen in the logs, in the form of the following message: "vmw_balloon: failed to initialize vmci doorbell" The driver would work correctly but slightly less efficiently, probing for requests periodically. This patch changes the balloon to be initialized using late_initcall() instead of module_init() to address this issue. It does not address a situation in which VMCI is built as a module and the balloon is built into the kernel.
