This is a note to let you know that I have just added a patch titled farsync: fix info leak in ioctl to the linux-3.5.y-queue branch of the 3.5.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From dab75c8b00a07776f4024d66c1bdb069da1db149 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Salva=20Peir=C3=B3?= <speiro@ai2.upv.es> Date: Fri, 11 Oct 2013 12:50:03 +0300 Subject: [PATCH] farsync: fix info leak in ioctl commit 96b340406724d87e4621284ebac5e059d67b2194 upstream. The fst_get_iface() code fails to initialize the two padding bytes of struct sync_serial_settings after the ->loopback member. Add an explicit memset(0) before filling the structure to avoid the info leak. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.
