This is a note to let you know that I have just added a patch titled fix sysvfs symlinks to the linux-3.16.y-queue branch of the 3.16.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.16.y-queue This patch is scheduled to be released in version 3.16.7-ckt22. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.16.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 9d02cebddca50757e1f6adca49693a893d80b1ef Mon Sep 17 00:00:00 2001 From: Al Viro <viro@zeniv.linux.org.uk> Date: Mon, 23 Nov 2015 21:11:08 -0500 Subject: fix sysvfs symlinks commit 0ebf7f10d67a70e120f365018f1c5fce9ddc567d upstream. The thing got broken back in 2002 - sysvfs does *not* have inline symlinks; even short ones have bodies stored in the first block of file. sysv_symlink() handles that correctly; unfortunately, attempting to look an existing symlink up will end up confusing them for inline symlinks, and interpret the block number containing the body as the body itself. Nobody has noticed until now, which says something about the level of testing sysvfs gets ;-/ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> [ luis: backported to 3.16: adjusted context ] Signed-off-by: Luis Henriques <luis.henriques@canonical.com> --- fs/sysv/inode.c | 10 ++-------- 1 file changed, 2 insertions(+), 8 deletions(-)
