1 Cryptsetup 1.4.2 Release Notes
2 ==============================
4 Changes since version 1.4.1
6 * Add --keyfile-offset and --new-keyfile-offset parameters to API and CLI.
7 These options can be used to skip start of keyfile or device used as keyfile.
9 * Add repair command and crypt_repair() for known LUKS metadata problems repair.
11 Some well-known LUKS metadata corruptions are easy to repair, this
12 command should provide a way to fix these problems.
14 Always create binary backup of header device before running repair,
15 (only 4kB - visible header) for example by using dd:
16 dd if=/dev/<LUKS header device> of=repair_bck.img bs=1k count=4
18 Then you can try to run repair:
19 cryptsetup repair <device>
21 Note, not all problems are possible to repair and if keyslot or some header
22 parameters are overwritten, device is lost permanently.
24 * Fix header check to support old (cryptsetup 1.0.0) header alignment.
27 * Allow to specify --align-payload only for luksFormat.
29 * Add --master-key-file option to luksOpen (open using volume key).
31 * Support UUID=<LUKS_UUID> format for device specification.
32 You can open device by UUID (only shortcut to /dev/disk/by-uuid/ symlinks).
34 * Support password verification with quiet flag if possible. (1.2.0)
35 Password verification can be still possible if input is terminal.
37 * Fix retry if entered passphrases (with verify option) do not match.
38 (It should retry if requested, not fail.)
40 * Fix use of empty keyfile.
42 * Fix error message for luksClose and detached LUKS header.
44 * Allow --header for status command to get full info with detached header.
