Cryptsetup 1.5.1 Release Notes ============================== Changes since version 1.5.0 * The libcryptsetup library now tries to initialize device-mapper backend and loop devices only if they are really needed (lazy initializations). This allows some operations to be run by a non-root user. (Unfortunately LUKS header keyslot operations still require temporary dm-crypt device and device-mapper subsystem is available only to superuser.) Also clear error messages are provided if running as non-root user and operation requires privileged user. * Veritysetup can be now used by a normal user for creating hash image to file and also it can create hash image if doesn't exist. (Previously it required pre-allocated space.) * Added crypt_keyslot_area() API call which allows external tools to get exact keyslot offsets and analyse content. An example of a tool that searches the keyslot area of a LUKS container for positions where entropy is low and hence there is a high probability of damage is in misc/kesylot_checker. (Thanks to Arno Wagner for the code.) * Optimized seek to keyfile-offset if key offset is large. * Fixed luksHeaderBackup for very old v1.0 unaligned LUKS headers. * Various fixes for problems found by a several static analysis tools.
