1 Cryptsetup 2.2.2 Release Notes
2 ==============================
3 Stable bug-fix release.
5 All users of cryptsetup 2.1 and 2.2 should upgrade to this version.
7 Changes since version 2.2.1
8 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
10 * Print error message if a keyslot open failed for a different reason
11 than wrong passwords (for example there is not enough memory).
12 Only an exit code was present in this case.
14 * The progress function switches unit sizes (B/s to GiB/s) according
15 to the actual speed. Also, it properly calculates speed in the case
16 of a resumed reencryption operation.
18 * The --version now supports short -V short option and better handles
19 common option priorities.
21 * If cryptsetup wipes signatures during format actions through blkid,
22 it also prints signature device offsets.
24 * Compilation now properly uses LTLIBINTL gettext setting in Makefiles.
26 * Device-mapper backend now supports new DM_GET_TARGET_VERSION ioctl
27 (available since Linux kernel 5.4).
28 This should help to detect some kernel/userspace incompatibilities
29 earlier later after a failed device activation.
31 * Fixes LUKS2 reencryption on systems without kernel keyring.
33 * Fixes unlocking prompt for partitions mapped through loop devices
34 (to properly show the backing device).
36 * For LUKS2 decryption, a device is now marked for deferred removal
37 to be automatically deactivated.
39 * Reencryption now limits hotzone size to be maximal 1 GiB or 1/4
40 system memory (if lower).
42 * Reencryption now retains activation flags during online reencryption.
44 * Reencryption now allows LUKS2 device to activate device right after
45 LUKS2 encryption is initialized through optional active device name
46 for cryptsetup reencrypt --encrypt command.
47 This could help with automated encryption during boot.
49 NOTE: It means that part of the device is still not encrypted during
50 activation. Use with care!
52 * Fixes failure in resize and plain format activation if activated device
53 size was not aligned to underlying logical device size.
55 * Fixes conversion to LUKS2 format with detached header if a detached
56 header size was smaller than the expected aligned LUKS1 header size.
