- cryptsetup 2.6.0:
* Introduce support for handling macOS FileVault2 devices (FVAULT2).
* libcryptsetup: no longer use global memory locking through mlockall()
* libcryptsetup: process priority is increased only for key derivation
(PBKDF) calls.
* Add new LUKS keyslot context handling functions and API.
* The volume key may now be extracted using a passphrase, keyfile, or
token. For LUKS devices, it also returns the volume key after
a successful crypt_format call.
* Fix --disable-luks2-reencryption configuration option.
* cryptsetup: Print a better error message and warning if the format
produces an image without space available for data.
* Print error if anti-forensic LUKS2 hash setting is not available.
If the specified hash was not available, activation quietly failed.
* Fix internal crypt segment compare routine if the user
specified cipher in kernel format (capi: prefix).
* cryptsetup: Add token unassign action.
This action allows removing token binding on specific keyslot.
* veritysetup: add support for --use-tasklets option.
This option sets try_verify_in_tasklet kernel dm-verity option
(available since Linux kernel 6.0) to allow some performance
improvement on specific systems.
* Provide pkgconfig Require.private settings.
While we do not completely provide static build on udev systems,
it helps produce statically linked binaries in certain situations.
* Always update automake library files if autogen.sh is run.
For several releases, we distributed older automake scripts by mistake.
* reencryption: Fix user defined moved segment size in LUKS2 decryption.
The --hotzone-size argument was ignored in cases where the actual data
size was less than the original LUKS2 data offset.
* Delegate FIPS mode detection to configured crypto backend.
System FIPS mode check no longer depends on /etc/system-fips file.
* Update documentation, including FAQ and man pages.

- cryptsetup 2.5.0:
* Split manual pages into per-action pages and use AsciiDoc format.
* Remove cryptsetup-reencrypt tool from the project and move reencryption
to already existing "cryptsetup reencrypt" command.
If you need to emulate the old cryptsetup-reencrypt binary, use simple
wrappers script running "exec cryptsetup reencrypt $@".
* LUKS2: implement --decryption option that allows LUKS removal.
* Fix decryption operation with --active-name option and restrict
it to be used only with LUKS2.
* Do not refresh reencryption digest when not needed.
This should speed up the reencryption resume process.
* Store proper resilience data in LUKS2 reencrypt initialization.
Resuming reencryption now does not require specification of resilience
type parameters if these are the same as during initialization.
* Properly wipe the unused area after reencryption with datashift in
the forward direction.
* Check datashift value against larger sector size.
For example, it could cause an issue if misaligned 4K sector appears
during decryption.
* Do not allow sector size increase reencryption in offline mode.
* Do not allow dangerous sector size change during reencryption.
* Ask the user for confirmation before resuming reencryption.
* Do not resume reencryption with conflicting parameters.
* Add --force-offline-reencrypt option.
* Do not allow nested encryption in LUKS reencrypt.
* Support all options allowed with luksFormat with encrypt action.
* Add resize action to integritysetup.
* Remove obsolete dracut plugin reencryption example.
* Fix possible keyslot area size overflow during conversion to LUKS2.
* Allow use of --header option for cryptsetup close.

- Update to 2.3.4:
* Fix a possible out-of-bounds memory write while validating LUKS2 data
segments metadata (CVE-2020-14382, boo#1176128).
* Ignore reported optimal IO size if not aligned to minimal page size.
* Added support for new no_read/write_wrokqueue dm-crypt options (kernel 5.9).
* Added support panic_on_corruption option for dm-verity devices (kernel 5.9).
* Support --master-key-file option for online LUKS2 reencryption
* Always return EEXIST error code if a device already exists.
* Fix a problem in integritysetup if a hash algorithm has dash in the name.
* Fix crypto backend to properly handle ECB mode.
* TrueCrypt/VeraCrypt compatible mode now supports the activation of devices
with a larger sector.
* LUKS2: Do not create excessively large headers.
* Fix unspecified sector size for BitLocker compatible mode.
* Fix reading key data size in metadata for BitLocker compatible mode.

* Support VeraCrypt 128 bytes passwords.
VeraCrypt now allows passwords of maximal length 128 bytes
(compared to legacy TrueCrypt where it was limited by 64 bytes).
* Strip extra newline from BitLocker recovery keys
There might be a trailing newline added by the text editor when
the recovery passphrase was passed using the --key-file option.
* Detect separate libiconv library.
It should fix compilation issues on distributions with iconv
implemented in a separate library.
* Various fixes and workarounds to build on old Linux distributions.
* Split lines with hexadecimal digest printing for large key-sizes.
* Do not wipe the device with no integrity profile.
With --integrity none we performed useless full device wipe.
* Workaround for dm-integrity kernel table bug.
Some kernels show an invalid dm-integrity mapping table
if superblock contains the "recalculate" bit. This causes
integritysetup to not recognize the dm-integrity device.
Integritysetup now specifies kernel options such a way that
even on unpatched kernels mapping table is correct.
* Print error message if LUKS1 keyslot cannot be processed.
If the crypto backend is missing support for hash algorithms
used in PBKDF2, the error message was not visible.
* Properly align LUKS2 keyslots area on conversion.
If the LUKS1 payload offset (data offset) is not aligned
to 4 KiB boundary, new LUKS2 keyslots area in now aligned properly.
* Validate LUKS2 earlier on conversion to not corrupt the device
if binary keyslots areas metadata are not correct.

- Update to 2.3.0 (include release notes for 2.2.0)
* BITLK (Windows BitLocker compatible) device access
* Veritysetup now supports activation with additional PKCS7 signature
of root hash through --root-hash-signature option.
* Integritysetup now calculates hash integrity size according to algorithm
instead of requiring an explicit tag size.
* Integritysetup now supports fixed padding for dm-integrity devices.
* A lot of fixes to online LUKS2 reecryption.
* Add crypt_resume_by_volume_key() function to libcryptsetup.
If a user has a volume key available, the LUKS device can be resumed
directly using the provided volume key.
No keyslot derivation is needed, only the key digest is checked.
* Implement active device suspend info.
Add CRYPT_ACTIVATE_SUSPENDED bit to crypt_get_active_device() flags
that informs the caller that device is suspended (luksSuspend).
* Allow --test-passphrase for a detached header.
Before this fix, we required a data device specified on the command
line even though it was not necessary for the passphrase check.
* Allow --key-file option in legacy offline encryption.
The option was ignored for LUKS1 encryption initialization.
* Export memory safe functions.
To make developing of some extensions simpler, we now export
functions to handle memory with proper wipe on deallocation.
* Fail crypt_keyslot_get_pbkdf for inactive LUKS1 keyslot.
* Add optional global serialization lock for memory hard PBKDF.
* Abort conversion to LUKS1 with incompatible sector size that is
not supported in LUKS1.
* Report error (-ENOENT) if no LUKS keyslots are available. User can now
distinguish between a wrong passphrase and no keyslot available.
* Fix a possible segfault in detached header handling (double free).
* Add integritysetup support for bitmap mode introduced in Linux kernel 5.2.
* The libcryptsetup now keeps all file descriptors to underlying device
open during the whole lifetime of crypt device context to avoid excessive
scanning in udev (udev run scan on every descriptor close).
* The luksDump command now prints more info for reencryption keyslot
(when a device is in-reencryption).
* New --device-size parameter is supported for LUKS2 reencryption.
* New --resume-only parameter is supported for LUKS2 reencryption.
* The repair command now tries LUKS2 reencryption recovery if needed.
* If reencryption device is a file image, an interactive dialog now
asks if reencryption should be run safely in offline mode
(if autodetection of active devices failed).
* Fix activation through a token where dm-crypt volume key was not
set through keyring (but using old device-mapper table parameter mode).
* Online reencryption can now retain all keyslots (if all passphrases
are provided). Note that keyslot numbers will change in this case.
* Allow volume key file to be used if no LUKS2 keyslots are present.
* Print a warning if online reencrypt is called over LUKS1 (not supported).
* Fix TCRYPT KDF failure in FIPS mode.
* Remove FIPS mode restriction for crypt_volume_key_get.
* Reduce keyslots area size in luksFormat when the header device is too small.
* Make resize action accept --device-size parameter (supports units suffix).

* The default size of the LUKS2 header is increased to 16 MB.
It includes metadata and the area used for binary keyslots;
it means that LUKS header backup is now 16MB in size.
* Cryptsetup now doubles LUKS default key size if XTS mode is used
(XTS mode uses two internal keys). This does not apply if key size
is explicitly specified on the command line and it does not apply
for the plain mode.
This fixes a confusion with AES and 256bit key in XTS mode where
code used AES128 and not AES256 as often expected.
* Default cryptographic backend used for LUKS header processing is now
OpenSSL. For years, OpenSSL provided better performance for PBKDF.
* The Python bindings are no longer supported and the code was removed
from cryptsetup distribution. Please use the libblockdev project
that already covers most of the libcryptsetup functionality
including LUKS2.
* Cryptsetup now allows using --offset option also for luksFormat.
* Cryptsetup now supports new refresh action (that is the alias for
"open --refresh").
* Integritysetup now supports mode with detached data device through
new --data-device option.
- 2.1.0 would use LUKS2 as default, we stay with LUKS1 for now until
someone has time to evaluate the fallout from switching to LUKS2.

- Suggest hmac package (boo#1090768)
- remove old upgrade hack for upgrades from 12.1
- New version 2.0.5
Changes since version 2.0.4
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Wipe full header areas (including unused) during LUKS format.
Since this version, the whole area up to the data offset is zeroed,
and subsequently, all keyslots areas are wiped with random data.
This ensures that no remaining old data remains in the LUKS header
areas, but it could slow down format operation on some devices.
Previously only first 4k (or 32k for LUKS2) and the used keyslot
was overwritten in the format operation.
* Several fixes to error messages that were unintentionally replaced
in previous versions with a silent exit code.
More descriptive error messages were added, including error
messages if
- a device is unusable (not a block device, no access, etc.),
- a LUKS device is not detected,
- LUKS header load code detects unsupported version,
- a keyslot decryption fails (also happens in the cipher check),
- converting an inactive keyslot.
* Device activation fails if data area overlaps with LUKS header.
* Code now uses explicit_bzero to wipe memory if available
(instead of own implementation).
* Additional VeraCrypt modes are now supported, including Camellia
and Kuznyechik symmetric ciphers (and cipher chains) and Streebog
hash function. These were introduced in a recent VeraCrypt upstream.
Note that Kuznyechik requires out-of-tree kernel module and
Streebog hash function is available only with the gcrypt cryptographic
backend for now.

Changes since version 2.0.3
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Use the libblkid (blockid) library to detect foreign signatures
on a device before LUKS format and LUKS2 auto-recovery.
This change fixes an unexpected recovery using the secondary
LUKS2 header after a device was already overwritten with
another format (filesystem or LVM physical volume).
LUKS2 will not recreate a primary header if it detects a valid
foreign signature. In this situation, a user must always
use cryptsetup repair command for the recovery.
Note that libcryptsetup and utilities are now linked to libblkid
as a new dependence.
To compile code without blockid support (strongly discouraged),
use --disable-blkid configure switch.
* Add prompt for format and repair actions in cryptsetup and
integritysetup if foreign signatures are detected on the device
through the blockid library.
After the confirmation, all known signatures are then wiped as
part of the format or repair procedure.
* Print consistent verbose message about keyslot and token numbers.
For keyslot actions: Key slot <number> unlocked/created/removed.
For token actions: Token <number> created/removed.
* Print error, if a non-existent token is tried to be removed.
* Add support for LUKS2 token definition export and import.
The token command now can export/import customized token JSON file
directly from command line. See the man page for more details.
* Add support for new dm-integrity superblock version 2.
* Add an error message when nothing was read from a key file.
* Update cryptsetup man pages, including --type option usage.

- new tarball / signature location
* Implement new erase (with alias luksErase) command.
* Add internal "whirlpool_gcryptbug hash" for accessing flawed
Whirlpool hash in gcrypt (requires gcrypt 1.6.1 or above).
* Allow to use --disable-gcrypt-pbkdf2 during configuration
to force use internal PBKDF2 code.
* Require gcrypt 1.6.1 for imported implementation of PBKDF2
(PBKDF2 in gcrypt 1.6.0 is too slow).
* Add --keep-key to cryptsetup-reencrypt.
