Subject: [PATCH 3.16.y-ckt 025/126] Btrfs: fix file corruption and data loss after cloning inline extents
Date: Wed, 9 Dec 2015 09:36:35 +0000 [thread overview]

In-Reply-To: <1449653896-5236-1-git-send-email-luis.henriques@canonical.com>
3.16.7-ckt21 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Filipe Manana <fdmanana@suse.com>
commit 8039d87d9e473aeb740d4fdbd59b9d2f89b2ced9 upstream.
Currently the clone ioctl allows to clone an inline extent from one file
to another that already has other (non-inlined) extents. This is a problem
because btrfs is not designed to deal with files having inline and regular
extents, if a file has an inline extent then it must be the only extent
in the file and must start at file offset 0. Having a file with an inline
extent followed by regular extents results in EIO errors when doing reads
or writes against the first 4K of the file.
Also, the clone ioctl allows one to lose data if the source file consists
of a single inline extent, with a size of N bytes, and the destination
file consists of a single inline extent with a size of M bytes, where we
have M > N. In this case the clone operation removes the inline extent
from the destination file and then copies the inline extent from the
source file into the destination file - we lose the M - N bytes from the
destination file, a read operation will get the value 0x00 for any bytes
in the the range [N, M] (the destination inode's i_size remained as M,
that's why we can read past N bytes).
So fix this by not allowing such destructive operations to happen and
return errno EOPNOTSUPP to user space.
Currently the fstest btrfs/035 tests the data loss case but it totally
ignores this - i.e. expects the operation to succeed and does not check
the we got data loss.
The following test case for fstests exercises all these cases that result
in file corruption and data loss:
seq=`basename $0`
seqres=$RESULT_DIR/$seq
