*** Problem description ***
btrfs/060 test of xfstests segfaults with unhandled signal 11 at 00003fff88820000 nip 0000000010065ac0 lr 0000000010065b18 code 30001 messages in dmesg.

Linux ubuntu 3.18.0-13-generic #14-Ubuntu SMP Fri Feb 6 09:57:41 UTC 2015 ppc64le ppc64le ppc64le GNU/Linux
*** Steps to reproduce ***
1. Power8 Machine installed Ubuntu 15.04 on a PowerVM LPAR.
2. Download git://oss.sgi.com/xfs/cmds/xfstests.git , compile and build
3. create 6 loop devices with btrfs file system on it.
4. local.config file will look like this:
export TEST_DEV=/dev/loop0
export TEST_DIR=/mnt/test
export SCRATCH_DEV_POOL="/dev/loop1 /dev/loop2 /dev/loop3 /dev/loop4 /dev/loop5"
export SCRATCH_MNT=/mnt/scratch
5. run the test : ./check btrfs/060
6. test failed with errors in dmesg and the command btrfsck core dumped.

The following upstream commit will fix the issue:
2c0e02a568c7db99922e9080407f8fc22d1991bd
Author: David Sterba <dsterba@suse.cz>

btrfs-progs: make free space checker work on non-4k sectorsize filesystems
The value of sector for space cache was hardcoded to 4k, and used to
calculate bitmap sizes. In kernel, the BITS_PER_BITMAP is derived from
PAGE_CACHE_SIZE which is not available for userspace, that can also deal
with filesystem of varying sectorsize.
Signed-off-by: David Sterba <dsterba@suse.cz>
Without this patch, In io_ctl_check_crc(), we end up passing an incorrect "length" value to the crc32c_le() function.
The patch (2c0e02a568c7db99922e9080407f8fc22d1991bd) needs to picked to help resolve this issue on Ubuntu. |
[Impact]
* fsck fails and uses incorrect sector size
[Test Case]
* see below
[Regression Potential]
* low, upstream patch used and tested in all later releases
