[ 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@tuxdriver.com> Reported-By: boyang@redhat.com CC: boyang@redhat.com CC: Shrikrishna Khare <skhare@vmware.com> CC: "VMware, Inc." <pv-drivers@vmware.com> CC: David S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
