Cryptsetup 2.8.2 Release Notes
==============================
Stable bug-fix release with minor extensions.

All users of cryptsetup 2.8.x must upgrade to this version.

Changes since version 2.8.1
~~~~~~~~~~~~~~~~~~~~~~~~~~~

* Fix cryptsetup LUKS2 status for HW inline integrity device.
  Cryptsetup status did not print the inline flag if the underlying device with
  HW integrity tags was used.

* Fix LUKS2 format with detached header and data device with HW integrity tags.

* Fix PBKDF serialization flag during device activation.
  The --serialize-memory-hard-pbkdf and CRYPT_ACTIVATE_SERIALIZE_MEMORY_HARD_PBKDF API flag
  is now properly supported again. This option is an optional workaround for situations where
  multiple devices are activated in parallel (e.g., systemd crypttab activation).

* BITLK: Add support for opening devices with Clear Key in BitLocker compatible mode.
  BitLocker devices that are not yet encrypted can contain a Clear Key that is not protected
  by a password. Cryptsetup can now map such devices and allow the user to access data on them.
  Note that while such a device is detected as BitLocker, it must be treated as an unencrypted
  device. Cryptsetup still does not allow mapping of partially encrypted BitLocker devices
  (those in the middle of the encryption process).

* BITLK: Harden metadata check by properly validating BitLocker metadata.
  BitLocker metadata store checksums and authentication tags to detect random or malicious
  manipulation. BITLK code now properly validates these and uses a backup metadata block
  if validation fails. Previously, only the first metadata block was used.

* Fix documentation to explicitly mention units for various API functions and in help messages.
  Note that due to compatibility reasons, cryptsetup arguments use key sizes in bits while
  integritysetup uses bytes.

* Fix handling of too-long labels and subsystem fields.
  LUKS2 labels are stored in the binary header area, which has a limited size.
  Cryptsetup no longer silently truncates too-long labels; it prints an error instead.

* Optimize reencryption to not repeatedly test access to the device.

* Allow to use PHMAC (protected HMAC) with integritysetup and cryptsetup.
  PHMAC is used by S390 mainframes. Support was added in Linux kernel 6.17. Configuration requires
  steps using s390-tools; once that's done, it can be handled as a common LUKS2 or integrity device.

* Opal2 SED: Fix misleading error messages during the self-encrypting drives format.
  Cryptsetup misinterpreted some error codes when the kernel interface was not available
  or the system call failed.

* Opal2 SED: Ensure the system tries to rescan the device after the PSID reset.
  Udev should now receive change events, allowing rescan of partition table after PSID reset.

* Fix typos in volume-key-file help and integritysetup man page.

* Fix detection of supported compiler attributes on PPC64 architecture.

* Fix const compilation warnings with new gcc and glibc headers.
