[PATCH 0/1] Check for eCryptfs cipher support at mount time.

[Tim Sally <tsally@xxxxxxxxxxxxxxx>]

eCryptfs will mount with any cipher supported by the crypto subsystem,
even if the cipher is not supported by eCryptfs itself. An error will
not occur until a write. This change checks for eCryptfs cipher
support at mount time and will not mount the filesystem if the cipher
is not supported.

The cipher name and blocksize are retrieved from ecryptfs_key_tfm
because it will assign a default block size upon creation if none
is specified in the mount options.

This issue originally reported by Tyler Hicks in 03/2009.
