Cryptsetup 1.4.2 Release Notes
==============================
Changes since version 1.4.1
* Add --keyfile-offset and --new-keyfile-offset parameters to API and CLI.
These options can be used to skip start of keyfile or device used as keyfile.
* Add repair command and crypt_repair() for known LUKS metadata problems repair.
Some well-known LUKS metadata corruptions are easy to repair, this
command should provide a way to fix these problems.
Always create binary backup of header device before running repair,
(only 4kB - visible header) for example by using dd:
dd if=/dev/<LUKS header device> of=repair_bck.img bs=1k count=4
Then you can try to run repair:
cryptsetup repair <device>
Note, not all problems are possible to repair and if keyslot or some header
parameters are overwritten, device is lost permanently.
* Fix header check to support old (cryptsetup 1.0.0) header alignment.
(Regression in 1.4.0)
* Allow to specify --align-payload only for luksFormat.
* Add --master-key-file option to luksOpen (open using volume key).
* Support UUID=<LUKS_UUID> format for device specification.
You can open device by UUID (only shortcut to /dev/disk/by-uuid/ symlinks).
* Support password verification with quiet flag if possible. (1.2.0)
Password verification can be still possible if input is terminal.
* Fix retry if entered passphrases (with verify option) do not match.
(It should retry if requested, not fail.)
* Fix use of empty keyfile.
* Fix error message for luksClose and detached LUKS header.
* Allow --header for status command to get full info with detached header.
