Title:
  ecryptfs fails to mount (Unable to link the KEY_SPEC_USER_KEYRING into
  the KEY_SPEC_SESSION_KEYRING)

Status in “ecryptfs-utils” package in Ubuntu:
  New
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  ecryptfs seems to be currently broken on Trusty.
  System: Trusty
  Linux: 3.13.0-8-generic #28-Ubuntu
  ecryptfs: 103-0ubuntu2 or 104-0ubuntu1

  Any attempt to mount fails with:
  Unable to link the KEY_SPEC_USER_KEYRING into the KEY_SPEC_SESSION_KEYRING; there is something wrong with your kernel keyring. Did you build key retention support into your kernel?

  
  Original reporter mentioned earlier kernel also:
  ------------------------------------------------

  I am using the fedora 19 default kernel, which should have ecryptfs
  support. I don't think something is wrong with my kernel. Nevertheless
  I get this strange error message. Googling it lead to nothing, so I
  suspect this is a bug in ecryptfs?

   iblue@silence  ~/ecrypt-test  lsmod | grep ecrypt
