Title:
btrfs and tar sparse truncate archives
Status in linux package in Ubuntu:
Fix Released
Status in tar package in Ubuntu:
New
Status in linux source package in Artful:
Fix Committed
Status in tar source package in Artful:
New
Bug description:
== SRU Justification ==
This bug causes btrfs and tar sparse to truncate archives. This bug has been
fixed in v4.15-rc3 by commit e3b8a4858566, which has a prereq commit of
f48bf66b662e.
These commits were cc'd to upstream stable and are already in Bionic.
However, upstream
4.13 is EOL, so Artful never recieved the fixes, which is the reason for
the SRU request.
== Fixes ==
f48bf66b662e ("Btrfs: move definition of the function
btrfs_find_new_delalloc_bytes")
e3b8a4858566 ("Btrfs: fix reported number of inode blocks after buffered
append writes")
== Regression Potential ==
Low. This fix was also sent and accepted to stable, so it has had additional
upstream review.
== Test Case ==
A test kernel was built with these patches and tested by the original bug
reporter.
The bug reporter states the test kernel resolved the bug.

3. Taring files into an archive are not truncated
4. Files included in tar are filled with NULLs
To reproduce, run an Artful system with one spare disk:
- mkfs.btrfs -f /dev/sda
- mount /dev/sda /mnt
- grep sda /proc/mounts
/dev/sda /mnt btrfs rw,relatime,space_cache,subvolid=5,subvol=/ 0 0
Then run this script which copies a 4MB binary to a btrfs filesystem,
tars the directory up containing the binary; then untars to stdout and
md5sum compares, showing it's different.
% SPARSE="-S"; rm -rf /mnt/tmp; md5sum /usr/bin/python3.6; mkdir -p /mnt/tmp;
cp -a /usr/bin/python3.6 /mnt/tmp; tar -C /mnt/tmp $SPARSE -czf /mnt/test.tgz
.; tar $SPARSE -xzf /mnt/test.tgz -O | md5sum
e4121d2f3126b8c364bfa1aaa82371a3 /usr/bin/python3.6
0ce8c4139740198926273853defcb12a -
And now without the sparse flag:
# SPARSE=""; rm -rf /mnt/tmp; md5sum /usr/bin/python3.6; mkdir -p /mnt/tmp;
cp -a /usr/bin/python3.6 /mnt/tmp; tar -C /mnt/tmp $SPARSE -czf /mnt/test.tgz
.; tar $SPARSE -xzf /mnt/test.tgz -O | md5sum
e4121d2f3126b8c364bfa1aaa82371a3 /usr/bin/python3.6
e4121d2f3126b8c364bfa1aaa82371a3 -
This has been reported to both gnu-tar and linux-btrfs; I'm not aware of an
actual fix.
Note that Xenial 4.4 kernels do not exhibit this behavior, and Bionic 4.15
kernel appears to be fixed as well though I'm not sure what the difference is.
