Hello,

This series adds an xfstest which tests that the encryption for
IV_INO_LBLK_64 encryption policies is being done correctly.

IV_INO_LBLK_64 is a new fscrypt policy flag which modifies the
encryption to be optimized for inline encryption hardware compliant with
the UFS v2.1 standard or the upcoming version of the eMMC standard.  For
more information, see the kernel patchset:
https://lore.kernel.org/linux-fscrypt/20191024215438.138489-1-ebiggers@kernel.org/T/#u

This is RFC for now since the kernel patches aren't in mainline yet
(they're queued for 5.5).

To run on ext4 this test also needs a version of e2fsprogs built from
the master branch, for support for the stable_inodes filesystem feature.

Eric Biggers (5):
  fscrypt-crypt-util: create key_and_iv_params structure
  fscrypt-crypt-util: add HKDF context constants
  common/encrypt: create named variables for UAPI constants
  common/encrypt: support verifying ciphertext of IV_INO_LBLK_64
    policies
  generic: verify ciphertext of IV_INO_LBLK_64 encryption policies
