* cryptsetup: upgrade 2.4.2 -> 2.4.3wangmy2022-01-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changelog: ========= Stable security bug-fix release that fixes CVE-2021-4122. All users of cryptsetup 2.4.x must upgrade to this version. Changes since version 2.4.2 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * Fix possible attacks against data confidentiality through LUKS2 online reencryption extension crash recovery (CVE-2021-4122). An attacker can modify on-disk metadata to simulate decryption in progress with crashed (unfinished) reencryption step and persistently decrypt part of the LUKS device. This attack requires repeated physical access to the LUKS device but no knowledge of user passphrases. The decryption step is performed after a valid user activates the device with a correct passphrase and modified metadata. There are no visible warnings for the user that such recovery happened (except using the luksDump command). The attack can also be reversed afterward (simulating crashed encryption from a plaintext) with possible modification of revealed plaintext. The size of possible decrypted data depends on configured LUKS2 header size (metadata size is configurable for LUKS2). With the default parameters (16 MiB LUKS2 header) and only one allocated keyslot (512 bit key for AES-XTS), simulated decryption with checksum resilience SHA1 (20 bytes checksum for 4096-byte blocks), the maximal decrypted size can be over 3GiB. The attack is not applicable to LUKS1 format, but the attacker can update metadata in place to LUKS2 format as an additional step. For such a converted LUKS2 header, the keyslot area is limited to decrypted size (with SHA1 checksums) over 300 MiB. The issue is present in all cryptsetup releases since 2.2.0. Versions 1.x, 2.0.x, and 2.1.x are not affected, as these do not contain LUKS2 reencryption extension. The problem was caused by reusing a mechanism designed for actual reencryption operation without reassessing the security impact for new encryption and decryption operations. While the reencryption requires calculating and verifying both key digests, no digest was needed to initiate decryption recovery if the destination is plaintext (no encryption key). Also, some metadata (like encryption cipher) is not protected, and an attacker could change it. Note that LUKS2 protects visible metadata only when a random change occurs. It does not protect against intentional modification but such modification must not cause a violation of data confidentiality. The fix introduces additional digest protection of reencryption metadata. The digest is calculated from known keys and critical reencryption metadata. Now an attacker cannot create correct metadata digest without knowledge of a passphrase for used keyslots. For more details, see LUKS2 On-Disk Format Specification version 1.1.0. The former reencryption operation (without the additional digest) is no longer supported (reencryption with the digest is not backward compatible). You need to finish in-progress reencryption before updating to new packages. The alternative approach is to perform a repair command from the updated package to recalculate reencryption digest and fix metadata. The reencryption repair operation always require a user passphrase. WARNING: Devices with older reencryption in progress can be no longer activated without performing the action mentioned above. Encryption in progress can be detected by running the luksDump command (output includes reencrypt keyslot with reencryption parameters). Also, during the active reencryption, no keyslot operations are available (change of passphrases, etc.). The issue was found by Milan Broz as cryptsetup maintainer. Other changes ~~~~~~~~~~~~~ * Add configure option --disable-luks2-reencryption to completely disable LUKS2 reencryption code. When used, the libcryptsetup library can read metadata with reencryption code, but all reencryption API calls and cryptsetup reencrypt commands are disabled. Devices with online reencryption in progress cannot be activated. This option can cause some incompatibilities. Please use with care. * Improve internal metadata validation code for reencryption metadata. * Add updated documentation for LUKS2 On-Disk Format Specification version 1.1.0 (with reencryption extension description and updated metadata description). See docs/on-disk-format-luks2.pdf or online version in https://gitlab.com/cryptsetup/LUKS2-docs repository. * Fix support for bitlk (BitLocker compatible) startup key with new metadata entry introduced in Windows 11. * Fix space restriction for LUKS2 reencryption with data shift. The code required more space than was needed. Signed-off-by: Wang Mingyu <wangmy@fujitsu.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>

All users of cryptsetup 2.4.0 should upgrade to this version. Changes since version 2.4.0 ~~~~~~~~~~~~~~~~~~~~~~~~~~~ * Fix compilation for libc implementations without dlvsym(). Some alternative libc implementations (like musl) do not provide versioned symbols dlvsym function. Code now fallbacks to dlsym operation for dynamic LUKS2 token load. It is up to maintainers to ensure that LUKS2 token plugins are compiled for the supported version. * Fix compilation and tests on systems with non-standard libraries (standalone argp library, external gettext library, BusyBox implementations of standard tools). * Try to workaround some issues on systems without udev support. NOTE: non-udev systems cannot provide all functionality for kernel device-mapper, and some operations can fail. * Fixes for OpenSSL3 crypto backend (including FIPS mode). Because cryptsetup still requires some hash functions implemented in OpenSSL3 legacy provider, crypto backend now uses its library context and tries to load both default and legacy OpenSSL3 providers. If FIPS mode is detected, no library context is used, and it is up to the OpenSSL system-wide policy to load proper providers. NOTE: We still use some deprecated API in the OpenSSL3 backend, and there are some known problems in OpenSSL 3.0.0. * Print error message when assigning a token to an inactive keyslot. * Fix offset bug in LUKS2 encryption code if --offset option was used. * Do not allow LUKS2 decryption for devices with data offset. Such devices cannot be used after decryption. * Fix LUKS1 cryptsetup repair command for some specific problems. Repair code can now fix wrongly used initialization vector specification in ECB mode (that is insecure anyway!) and repair the upper-case hash specification in the LUKS1 header.

| | | | | | | | | | | | | | | | | | | | Otherwise cryptsetup-native depends on the target kernel and thus the target compiler, as can be seen by: $ bitbake -g cryptsetup-native $ grep 'cryptsetup.*linux-yocto' task-depends.dot "cryptsetup-native.do_build" -> "linux-yocto.do_deploy" "cryptsetup-native.do_build" -> "linux-yocto.do_package_write_rpm" "cryptsetup-native.do_populate_sysroot" -> "linux-yocto.do_populate_sysroot" $ grep 'linux-yocto.*gcc-cross' task-depends.dot "linux-yocto.do_kernel_configme" -> "gcc-cross-x86_64.do_populate_sysroot" "linux-yocto.do_prepare_recipe_sysroot" -> "gcc-cross-x86_64.do_populate_sysroot" This also moves the runtime dependencies to near the end of the recipe, which is more customary.

| | | | | | | | | | | | | | | | | The util-linux recipe in Poky has been split, and libuuid is separate now: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=d42487bf52310d095178e480b7ddec2666471009 This allows to build util-linux with cryptsetup, for native dm-verity support. The main cryptsetup build needs libuuid and not the full util-linux, so switch the build-dependency over, thus allowing users to enable the cryptsetup util-linux's PACKAGECONFIG. The libblkid dependency is handled individually by the crypsetup's PACKAGECONFIG option. Signed-off-by: Luca Boccassi <luca.boccassi@microsoft.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>

* cryptsetup: set the default luks format to LUKS1Yi Zhao2019-07-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cryptsetup 2.1 uses LUKS2 format as the default LUKS format. This change introduced the following issues: * LUKS2 requires kernel userspace crypto API to be available (CONFIG_CRYPTO_USER_API and CONFIG_CRYPTO_USER_API_SKCIPHER). But linux-yocto doesn't enable these options by default. If missing these kernel modules, the cryptsetup will fall back to using dmcrypt-device for keyslot processing. $ cryptsetup --debug --type luks luksFormat /dev/sda3 [snip] Checking if cipher aes-xts-plain64 is usable. Userspace crypto wrapper cannot use aes-xts-plain64 (-95). Using dmcrypt to access keyslot area. [snip] * The grub can not decrypt a LUKS2 encrypted boot partition because it doesn't support LUKS2 now. See grub bug: https://savannah.gnu.org/bugs/?55093 Add a PACKAGCONFIG for luks format and set the default LUKS format to LUKS1. The users can specify '--type luks2' in cryptsetup command line if they want to use LUKS2. Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Khem Raj <raj.khem@gmail.com>
* cryptsetup: Don't enable udev for native buildRobert Joslyn2019-07-101-2/+4
| | | | | | | | | | | | | | When building cryptsetup-native, don't enable udev support since there is not a udev-native recipe. When udev is enabled, change the dependency from a DEPENDS to an RDEPENDS. The --enable-udev option adds a runtime check for udev before using udev features of libdevmapper. Because of this, udev isn't needed at build time, just runtime.
