Cryptsetup 2.6.1 Release Notes
==============================
Stable bug-fix release with minor extensions.
All users of cryptsetup 2.6.0 should upgrade to this version.
Changes since version 2.6.0
~~~~~~~~~~~~~~~~~~~~~~~~~~~
* bitlk: Fixes for BitLocker-compatible on-disk metadata parser
(found by new cryptsetup OSS-Fuzz fuzzers).
- Fix a possible memory leak if the metadata contains more than
one description field.
- Harden parsing of metadata entries for key and description entries.
- Fix broken metadata parsing that can cause a crash or out of memory.
* Fix possible iteration overflow in OpenSSL2 PBKDF2 crypto backend.
OpenSSL2 uses a signed integer for PBKDF2 iteration count.
As cryptsetup uses an unsigned value, this can lead to overflow and
a decrease in the actual iteration count.
This situation can happen only if the user specifies
--pbkdf-force-iterations option.
OpenSSL3 (and other supported crypto backends) are not affected.
* Fix compilation for new ISO C standards (gcc with -std=c11 and higher).
* fvault2: Fix compilation with very old uuid.h.
* verity: Fix possible hash offset setting overflow.
* bitlk: Fix use of startup BEK key on big-endian platforms.
* Fix compilation with latest musl library.
Recent musl no longer implements lseek64() in some configurations.
Use lseek() as 64-bit offset is mandatory for cryptsetup.
* Do not initiate encryption (reencryption command) when the header and
data devices are the same.
If data device reduction is not requsted, this leads to data corruption
since LUKS metadata was written over the data device.
* Fix possible memory leak if crypt_load() fails.
* Always use passphrases with a minimal 8 chars length for benchmarking.
Some enterprise distributions decided to set an unconditional check
for PBKDF2 password length when running in FIPS mode.
This questionable change led to unexpected failures during LUKS format
and keyslot operations, where short passwords were used for
benchmarking PBKDF2 speed.
PBKDF2 benchmark calculations should not be affected by this change.

Similar to mdadm also cryptsetup now requires _LARGEFILE64_SOURCE.
Add -D_LARGEFILE64_SOURCE to TARGET_CFLAGS to fix compilation.

Use PKG_FIXUP:=autoreconf when building cryptsetup to prevent
accidental linkage against host libraries.

Use PKG_INSTALL for consistency between packages.
Add PKG_BUILD_PARALLEL for faster compilation.
Fix wrong locking path. First discovered here:

This removes lines that set PKG_BUILD_DIR when the set value is no
different from the default value.
Specifically, the line is removed if the assigned value is:
* $(BUILD_DIR)/$(PKG_NAME)-$(BUILD_VARIANT)/$(PKG_NAME)-$(PKG_VERSION)
The default PKG_BUILD_DIR was updated[1] to incorporate BUILD_VARIANT
if it is set, so now this is identical to the default value.
* $(BUILD_DIR)/$(PKG_NAME)-$(BUILD_VARIANT)/$(PKG_SOURCE_SUBDIR)
if PKG_SOURCE_SUBDIR is set to $(PKG_NAME)-$(PKG_VERSION), making it
the same as the previous case
* $(BUILD_DIR)/$(PKG_NAME)-$(PKG_VERSION)
This is the same as the default PKG_BUILD_DIR when there is no
BUILD_VARIANT.
* $(BUILD_DIR)/[name]-$(PKG_VERSION)
where [name] is a string that is identical to PKG_NAME

The CONTRIBUTING.md requests an (or multiple) SPDX identifier for GPL
licenses. But a lot of packages did use a different, non-SPDX style with a
"+" at the end instead of "-or-later".

OpenSSL is only used for hashing while being a huge dependency (689.4KB
for mips_24kc.
Cryptsetup also supports and recommends argon2 for hashing, which is not
provided by OpenSSL.

Add several configure arguments to speed up build time.
Switch from using libgcrypt to using the kernel directly.
This has a number of benefits including smaller size and faster speed. It
also allows selection of desired crypto primatives instead of having all
of them.
