Cryptsetup 1.7.5 Release Notes
==============================

Changes since version 1.7.4

* Fixes to luksFormat to properly support recent kernel running in FIPS mode.

  Cryptsetup must never use a weak key even if it is just used for testing
  of algorithm availability. In FIPS mode, weak keys are always rejected.

  A weak key is for example detected if the XTS encryption mode use
  the same key for the tweak and the encryption part.

* Fixes accesses to unaligned hidden legacy TrueCrypt header.

  On a native 4k-sector device the old hidden TrueCrypt header is not
  aligned with the hw sector size (this problem was fixed in later TrueCrypt
  on-disk format versions).

  Cryptsetup now properly aligns the read so it does not fail.

* Fixes to optional dracut ramdisk scripts for offline re-encryption on initial boot.
