This is a note to let you know that I have just added a patch titled net: fix uninitialized variable issue to the linux-4.2.y-queue branch of the 4.2.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-4.2.y-queue This patch is scheduled to be released in version 4.2.8-ckt1. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 4.2.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 4c5440642275531fcc4edc3d5dc654aece49606b Mon Sep 17 00:00:00 2001 From: "tadeusz.struk@intel.com" <tadeusz.struk@intel.com> Date: Tue, 15 Dec 2015 10:46:17 -0800 Subject: net: fix uninitialized variable issue [ Upstream commit 130ed5d105dde141e7fe60d5440aa53e0a84f13b ] msg_iocb needs to be initialized on the recv/recvfrom path. Otherwise afalg will wrongly interpret it as an async call.
