Paul Lawrence 236e5e800e Make ext4 userdata checkpoints work with metadata encryption ... When both ext4 user data checkpoints and metadata encryption are enabled, we are creating two stacked dm devices. This had not been properly thought through or debugged. Test: Enable metadata encryption on taimen (add keydirectory=/metadata/vold/metadata_encryption to flags for userdata in fstab.hardware) Unfortunately metadata is not wiped by fastboot -w, so it is necessary to rm metadata/vold -rf whenever you wipe data. fastboot flashall -w works fastboot reboot -w works A normal boot works Disable checkpoint commits with setprop persist.vold.dont_commit_checkpoint 1 vdc checkpoint startCheckpoint 10 adb reboot wait for device to fully boot then adb reboot Wait for device to fully boot then adb logcat -d | grep Checkpoint shows the rollback in the logs This tests encryption on top of checkpoints with commit, encryption without checkpoints, and rollback, which seems to be the key cases.
