This is a note to let you know that I have just added a patch titled ext4: fix an endianness bug in ext4_encrypted_zeroout() 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-ckt2. 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 ---8<------------------------------------------------------------ From db0431b548cd683bf7863aed1c5bcd7c6f6572c1 Mon Sep 17 00:00:00 2001 From: Al Viro <viro@ZenIV.linux.org.uk> Date: Thu, 26 Nov 2015 15:20:19 -0500 Subject: ext4: fix an endianness bug in ext4_encrypted_zeroout() commit e2c9e0b28e146c9a3bce21408f3c02e24ac7ac31 upstream. ex->ee_block is not host-endian (note that accesses of other fields of *ex right next to that line go through the helpers that do proper conversion from little-endian to host-endian; it might make sense to add similar for ->ee_block to avoid reintroducing that kind of bugs...)
