Subject: Testing Ext4 encryption with fstests
Date: Sat, 02 Dec 2017 08:44:29 +0530 [thread overview]
Message-ID: <2008991.n3x73QCyP8@localhost.localdomain> (raw)
Hi,
I have now got an initial version of patch to get encryption to work on
blocksize < pagesize
(https://github.com/chandanr/linux/commit/343ef14a6c33fd3fc4bda11a2ffa6de8cd695f04).
There is still some error handling code to be written.
My fstests local.config has,
export TEST_DEV=/dev/loop0
export TEST_DIR=/mnt/btrfs-xfstest-test
export SCRATCH_DEV=/dev/loop1
export SCRATCH_MNT=/mnt/btrfs-xfstest-scratch
MKFS_OPTIONS="-O encrypt"
EXT_MOUNT_OPTIONS="-o test_dummy_encryption"
export FSTYPE=ext4
With the latest linux-next next-20171201 (i.e. without my changes applied)
on x86 I see some tests fail and also filesystem consistency almost always
fails. E.g.
_check_generic_filesystem: filesystem on /dev/loop0 is inconsistent
(see /root/xfstests-dev/results//check.full for details)
generic/011 1s ... 0s
_check_generic_filesystem: filesystem on /dev/loop0 is inconsistent
(see /root/xfstests-dev/results//generic/011.full for details)
