  eCryptfs: don't pass fs-specific ioctl commands through (2015-03-03 02:03:56 -0600)

----------------------------------------------------------------
Fixes for proper ioctl handling and an untriggerable buffer overflow
- The eCryptfs ioctl handling functions should only pass known-good ioctl
  commands to the lower filesystem
- A static checker found a potential buffer overflow. Upon inspection, it is
  not triggerable due to input validation performed on the mount parameters.
