Public bug reported:
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
ls: cannot access 'Contracts': No such file or directory
ls: cannot access 'Documents': No such file or directory
ls: cannot access 'Work': No such file or directory

drwxr-x--- 5 redsandro redsandro 4.0K Mar 31 15:54 ./

d????????? ? ? ? ? ? Contracts/
d????????? ? ? ? ? ? Documents/
d????????? ? ? ? ? ? Work/
The other machine still works fine.
4.4.0-53-generic:
$ ll

For both machines:
$ apt version ecryptfs-utils
