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