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) Ran: generic/011 Failures: generic/011 Failed 1 of 1 tests FSTYP -- ext4 PLATFORM -- Linux/x86_64 localhost 4.13.0-next-20170905-gf165385 MKFS_OPTIONS -- -O encrypt /dev/loop1 MOUNT_OPTIONS -- -o acl,user_xattr -o test_dummy_encryption /dev/loop1 /mnt/btrfs-xfstest-scratch _check_generic_filesystem: filesystem on /dev/loop0 is inconsistent (see /root/xfstests-dev/results//check.full for details) generic/012 0s ...
