I have tried 3 different laptops with 3 different distro's.
Ubuntu 16.04.1, Ubuntu 16.04.3 and Linux Mint 17.
Also I've tried about 8 different kernels.
For that reason, a bug report with apport-collect, containing all my
hardware serials and stored wifi connections, seems irrelevant. I'm
marking this bug confirmed, as instructed by the Kernel Bot.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Description changed:
- I have two systems that have a Dropbox folder synced. One of the
- subfolders contains sensitive data encrypted using ecryptfs. Both were
- running linux kernel 4.4.0-53-generic.
+ UPDATE:
+
+ I think the problem only exists for unencrypted filenames that would
+ previously pass (by default or) by passing the ecryptfs_passthrough
+ option.
+
+ Unencrypted filenames work as expected on kernels <=4.4, but are
+ inaccessable and listed as ???????? in kernels >=4.8.
+
+ Original report below:
+
+ --------
+
+
+ I have two systems that have a Dropbox folder synced. One of the subfolders
contains sensitive data encrypted using ecryptfs. Both were running linux
kernel 4.4.0-53-generic.
I have since upgraded one system to use linux kernel 4.8.0-41-generic.
Now, the decrypted directory can no longer see groups and owners or read
files. All permissions are replaced by questionmarks.
4.8.0-41-generic
$ ll

The other machine still works fine.
