Public bug reported:

Binary package hint: ecryptfs-utils

When configuring an eCryptfs directory as specified in
http://ecryptfs.sourceforge.net/README, I cannot decrypt the stored
files any more after unmounting / mounting the directory:

$ echo hello > ~/Secret/test.txt
$ cat ~/Secret/test.txt
hello
$ umount ~/Secret
$ mount -i ~/Secret
$ cat ~/Secret/test.txt
cat: /home/vlc/Secret/test.txt: Input/output error

The following errors can be found in the system log:

> The lower file appears to be a non-encrypted eCryptfs file; this is not supported in this version of the eCryptfs kernel module
> Error attempting to read the [user.ecryptfs] xattr from the lower file; return value = [4294967201]
> Valid eCryptfs headers not found in file header region or xattr region
> Attempt to read file that is not in a valid eCryptfs format, and plaintext passthrough mode is not enabled; returning -EIO

Ubuntu version: 8.04.1
ecryptfs-utils version: 38-2

Attached in file ecryptfs.txt please find the exact steps I executed to
configure the eCryptfs directory.
