This is a note to let you know that I have just added a patch titled fs, omfs: add NULL terminator in the end up the token list to the linux-3.13.y-queue branch of the 3.13.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11-ckt23. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 5ec5a53b6c560cece6fa321bcfa565c301e25a1a Mon Sep 17 00:00:00 2001 From: Sasha Levin <sasha.levin@oracle.com> Date: Thu, 28 May 2015 15:44:29 -0700 Subject: fs, omfs: add NULL terminator in the end up the token list commit dcbff39da3d815f08750552fdd04f96b51751129 upstream. match_token() expects a NULL terminator at the end of the token list so that it would know where to stop. Not having one causes it to overrun to invalid memory. In practice, passing a mount option that omfs didn't recognize would sometimes panic the system.
