[Linux-stable-mirror] [PATCH 4.4] vsyscall: Fix permissions for emulate mode with KAISER/PTI

by Ben Hutchings

The backport of KAISER to 4.4 turned vsyscall emulate mode into native mode. Add a vsyscall_pgprot variable to hold the correct page protections, like Borislav and Hugh did for 3.2 and 3.18.

[Linux-stable-mirror] Patch "vmxnet3: repair memory leak" 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 vmxnet3: repair memory leak 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: vmxnet3-repair-memory-leak.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 foo@baz Sun Jan 28 17:37:09 CET 2018 From: Neil Horman <nhorman(a)tuxdriver.com> Date: Mon, 22 Jan 2018 16:06:37 -0500 Subject: vmxnet3: repair memory leak From: Neil Horman <nhorman(a)tuxdriver.com> [ Upstream commit 848b159835ddef99cc4193083f7e786c3992f580 ] with the introduction of commit b0eb57cb97e7837ebb746404c2c58c6f536f23fa, it appears that rq->buf_info is improperly handled. While it is heap allocated when an rx queue is setup, and freed when torn down, an old line of code in vmxnet3_rq_destroy was not properly removed, leading to rq->buf_info[0] being set to NULL prior to its being freed, causing a memory leak, which eventually exhausts the system on repeated create/destroy operations (for example, when the mtu of a vmxnet3 interface is changed frequently. Fix is pretty straight forward, just move the NULL set to after the free. Tested by myself with successful results Applies to net, and should likely be queued for stable, please Signed-off-by: Neil Horman <nhorman(a)tuxdriver.com> Reported-By: boyang(a)redhat.com CC: boyang(a)redhat.com CC: Shrikrishna Khare <skhare(a)vmware.com> CC: "VMware, Inc." <pv-drivers(a)vmware.com> CC: David S.
