Package: e2fsprogs
Version: 1.44.5-1
Severity: normal
Tags: lfs
Dear Maintainer,
I created a rootfs containing a file with a size greater than 5G. I
used mkfs to apply the rootfs on an image. If I applied the Image the
file had changed (verified with md5sum). This bug is fixed upstream[1] with
version 1.44.6. The fixing commit is 1eec7413677ee15182470928c7236969d32d8426.
[1] git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
Steps to reproduce:
mkdir rootfs
dd if=/dev/urandom of=rootfs/bigfile bs=4M count=1280
dd if=/dev/zero of=image bs=4M count=2000
mkfs.ext4 image -d rootfs
mount -o loop,ro image /mnt
md5sum rootfs/bigfile /mnt/bigfile
Kind regards
Quirin

Unfortunatelly, 1.44.6 didn't make the Debian Buster freeze, and the
bug isn't sufficiently serious, so a bugfix for it won't be accepted
by the Debian Release Team for Debian Stable.
Since it has been fixed in Debian Testing, if you need a fixed version
for Debian Stable, I suggest that you use the version of e2fsprogs
from Debian Backports[1], which is currently version
1.45.3-3~bpo10+1[2].
