Release notes for 5.3 (whinlatter)

New Features / Enhancements in 5.3

  • Linux kernel 6.16, gcc 15, glibc 2.42, LLVM 21.1.1, and over 300 other recipe upgrades.

  • Minimum Python version required on the host: 3.9.

  • Host requirements changes:

    • The minimum disk space requirement is now 140Gbytes (previously 90Gbytes).

    • The minimum RAM requirement is now 32Gbytes (previously 8Gbytes).

    • These changes are mainly due to recent additions of the LLVM and other resource heavy recipes. For guidance on how to limit the resources used by the OpenEmbedded Build System, see the Limiting the Host Resources Usage guide.

  • BitBake changes:

    • codeparser: Add function decorators for vardeps

      Adds bb.parse.vardeps and bb.parse.excludevardeps function decorators that can be used to explicitly add or exclude variables from a Python function parsed by BitBake.

      Move vardepexclude flag entries alongside functions for maintainability.

    • Fetcher:

      • Check for git-lfs existence before using it.

      • Add support for .debs files containing uncompressed data tarballs.

      • az: Add sanity check to check that AZ_SAS starts with ? to mark the start of the query parameters.

      • git:

        • Add the tag to shallow clone tarball name.

        • Verify if local clones contains a tag, when the tag= parameter is used in SRC_URI.

    • knotty:

      • Pass failed task logs through the log infrastructure (use bb.plain() instead of print()).

      • Improve refresh rate of the footer progress bar.

    • Add support for automatically promoting class inherits to deferred inherits by listing them in the BB_DEFER_BBCLASSES variable.

    • “Built-in” fragments support is now added to the addfragments directive. This is the fourth parameter to this directive, and should be the name of the variable that contains definitions of built-in fragments. Refer to the documentation of addfragments to learn how to define new built-in fragments.

      Listing these built-in fragments can be done with bitbake-config-build list-fragments, which could list:

      Available built-in fragments:
machine/...     Sets MACHINE = ...
distro/...      Sets DISTRO = ...

      In the above example, this means that the MACHINE of DISTRO can be overridden with:

      OE_FRAGMENTS += "machine/qemuarm64 distro/poky-bleeding"

      This would set MACHINE to qemuarm64 and the DISTRO to poky-bleeding.

    • The tag- parameter in URLs can now be specified alongside the rev= parameter and SRCREV variable, and will ensure that the specified tag matches the specified revision.

      It is strongly encouraged to include the tag= parameter to the SRC_URI definition when possible.

    • tinfoil: add a wait_for decorator to wrap a function that makes an asynchronous tinfoil call wait for event to say that the call has been successful, or an error has occurred.

    • New bb.utils.to_filemode() helper function which is a helper to take a variable’s content containing a filemode and convert it to the proper Python representation of the number.

    • cooker: Use a shared counter for processing parser jobs. This allows the parser processes to run independently of needing to be feed by the parent process, and load balances them much better.

    • cooker/process/utils: Add a -P (--profile) option to BitBake to specify what to profile. Can be “main”, “idle” or “parsing”. Split the reports in separate files.

    • A “filtering” functionality was added and allows modifying the value of a variable before its value is returned by BitBake. The setVarFilter API can be used for applying the filters, but it is not recommended for general use. It was added for internal use in the OpenEmbedded Build System in the native class. The list of filters that are allowed are derived from a select list of functions that must be added using a filter_proc decorator.

    • tests/parse: Add tests for include, require and include_all.

  • Toolchain changes:

  • Global configuration changes:

    • bitbake.conf/pseudo: Switch from exclusion list to inclusion list by swapping PSEUDO_IGNORE_PATHS for PSEUDO_INCLUDE_PATHS which should be easier and more explicit to maintain.

    • bitbake.conf: Drop lz4 from HOSTTOOLS, as it is not required anymore, and the lz4-native package is used instead.

    • Configuration Fragments:

      • Add a fragment for the CDN sstate-cache mirror.

      • Add a show-fragments sub-command to the bitbake-config-build utility, to show the content of fragments from command-line.

    • default-distrovars: set an empty default for LICENSE_PATH.

    • The default definition of UNPACKDIR is no longer sources-unpack but sources.

    • The default value for IMAGE_FSTYPES (defined in bitbake.conf) is now tar.zst (previously tar.gz).

    • Remove the meta/conf/distro/include/distro_alias.inc include file, which associated a recipe name to one or more Distribution package name. This file is not used and maintained anymore.

    • A new configuration file build/conf/toolcfg.conf is now used by bitbake-config-build to manage Configuration Fragments.

    • bitbake.conf: add TMPDIR to the GIT_CEILING_DIRECTORIES Git variable. This avoids Git trying to find a repository higher than TMPDIR in recipes that use the build/tmp/work-shared/ directory for storing their sources. This fixes reproducibility issues.

    • Changes to the genericarm64 machine configuration:

      • Increase the Initramfs maximum size.

      • Install extra Linux firmware packages to fix Linux kernel warnings.

  • New variables:

    • The VIRTUAL-RUNTIME_dbus variable, to allow changing the runtime implementation of D-Bus. See VIRTUAL-RUNTIME.

    • The VIRTUAL-RUNTIME_libsdl2 variable, to allow changing the runtime implementation of libsdl2. See VIRTUAL-RUNTIME.

    • The SPDX_PACKAGE_URL variable can be used in recipes to set the output software_packageUrl field in their associated SPDX 3.0 output (default value: empty string).

    • The KMETA_CONFIG_FEATURES variable can be used to control kernel-yocto configuration features. For now only prefer-modules is supported for this variable.

    • The TESTSDK_SUITES variable can be used to control the list of tests run for the testsdk class.

    • The UBOOT_FIT_CONF_FIRMWARE can be used to specify a firmware entry in the configuration node of a FIT image.

    • The SPDX_INCLUDE_COMPILED_SOURCES option allows the same as SPDX_INCLUDE_SOURCES but including only the sources used to compile the host tools and the target packages.

    • The UBOOT_VERSION variable holds the package version (PV) and revision (PR) which are part of the installed and deployed filenames. Users can now override UBOOT_VERSION to changes the output filenames.

    • The UBOOT_MAKE_OPTS variable specifies extra options passed to make when building U-boot. Extra options can also be passed as the fourth argument of the UBOOT_CONFIG variable. See the documentation of uboot-config class for more details.

  • Kernel-related changes:

    • linux/generate-cve-exclusions: use data from CVEProject instead of the archived https://linuxkernelcves.com.

    • kernel-yocto: allow annotated options to be modified. For example if the following kernel configuration is set:

      CONFIG_INET_TUNNEL=y # OVERRIDE:$MODULE_OR_Y

      And if the KMETA_CONFIG_FEATURES variable contains prefer-modules, CONFIG_INET_TUNNEL will be set to m instead of y.

    • kernel-devsrc: Replace the extra System.map file with symbolic link.

    • kernel-module-split: Allow for external configuration files being assigned to the correct kernel module package.

    • When built for the RISC-V architecture, ensure that the minimum required features set by TUNE_FEATURES are set using the features_check class.

    • linux-yocto: when built for RISC-V, enable features in KERNEL_FEATURES based on features listed in TUNE_FEATURES.

    • perf: Enable coresight if enabled in MACHINE_FEATURES.

  • New core recipes:

    • python3-pdm, python3-pdm-backend and python3-pdm-build-locked, which are dependencies of python3-webcolors. python3-pdm itself depends on python3-pdm-build-locked

    • bindgen-cli: a tool to generate Rust bindings.

    • python3-colorama: Cross-platform colored terminal text, needed by pytest as a dependency.

    • libglvnd: imported from meta-oe which provides a vendor neutral approach to handling OpenGL / OpenGL ES / EGL / GLX libraries.

    • python3-sphinx-argparse: A sphinx extension that automatically documents argparse commands and options. It is part of buildtools-docs-tarball for later use in the Yocto Project documentation.

    • python3-sphinx-copybutton: A sphinx extension that adds a copy button to code blocks in Sphinx. It is part of buildtools-docs-tarball for later use in the Yocto Project documentation.

    • python3-coherent-licensed: License management tooling for Coherent System and skeleton projects. It became a new dependency of python3-zipp.

    • gn: a commonly used build tool to generate ninja files.

    • LLVM/Clang related recipes:

      • clang: LLVM based C/C++ compiler.

      • compiler-rt: LLVM based C/C++ compiler Runtime.

      • libclc: Implementation of the library requirements of the OpenCL C programming language.

      • libcxx: new implementation of the C++ standard library, targeting C++11 and above

      • llvm-tblgen-native: LLVM TableGen binaries for the build host, often used to build LLVM projects.

      • openmp: LLVM OpenMP compiler Runtime.

  • kernel-signing-keys-native: this recipe is used in the kernel-fit-image class to generate a pair of RSA public/private key. It replaces the do_generate_rsa_keys of the kernel-fit-image class.

  • New DISTRO_FEATURES:

    • glvnd, which enables OpenGL Vendor Neutral Dispatch Library support when using recipes such as mesa.

    • opencl: support for the OpenCL (Open Computing Language) framework.

  • New core classes:

    • The new kernel-fit-image class replaces the previous kernel-fitimage class. It has been rewritten and improved to fix bug 12912. See the Removed Classes section of the Migration notes for 5.3 (whinlatter) for more details on how to switch to this new class.

    • The new go-mod-update-modules class can be used to maintain Go recipes that use a BPN-go-mods.inc and BPN-licenses.inc and update these files automatically.

    • The new python_pdm class supports building Python recipes with the PDM package and dependency manager.

  • Architecture-specific changes:

    • Rework the RISC-V TUNE_FEATURES to make them based of the RISC-V ISA (Instruction Set Architecture) implementation.

      This implements the following base ISAs:

      • rv32i, rv64i

      • rv32e, rv64i

      The following ABIs:

      • ilp32, ilp32e, ilp32f, ilp32d

      • Zbb: Basic bit manipulation extension

      • Zbc: Carry-less multiplication extension

      • Zbs: Single-bit manipulation extension

      • Zicbom: Cache-block management extension

      The existing processors tunes are preserved:

      • riscv64 (rv64gc)

      • riscv32 (rv32gc)

      • riscv64nf (rv64imac_zicsr_zifencei)

      • riscv32nf (rv32imac_zicsr_zifencei)

      • riscv64nc (rv64imafd_zicsr_zifencei)

      See meta/conf/machine/include/riscv/README for more information.

    • Add support for new Arm64 instruction sets, which are represented as files to be included in MACHINE configuration in OpenEmbedded-Core (OE-Core). The new configuration files are:

    • arch-mips.inc: Use -EB/-EL for denoting Endianness.

    • Enable riscv32 as supported arch for musl systems.

    • Powerpc: Use -maltivec in compiler flags if altivec is in TUNE_FEATURES.

    • arm: add a nocrypto feature to TUNE_FEATURES to complement the crypto feature to explicitly disable cryptographic extensions via GCC flags.

      This lead to the creation of two new tunes:

      • tune-cortexa72-nocrypto

      • tune-cortexa53-nocrypto

  • QEMU / runqemu changes:

    • Refactor qemu functions into library functions (in lib/oe/qemu.py).

    • The qemux86-64 MACHINE now defaults to the x86-64-v3 micro-architecture level.

      The previous default was Core 2 era processors. This change means that the toolchain is configured to build for that level, and QEMU is configured to emulate it.

      The v3 level adds support for AVX/AVX2/BMI/BMI2/F16C and other newer instructions which are seeing increasing usage in modern software and add performance benefits. Please see X86-64 Microarchitecture levels for definition of the levels and lists of Intel/AMD CPUs where support for the instructions was first added.

      Note that if QEMU system emulation is used on an x86 build machine with KVM enabled, then the build machine’s CPU must also be recent enough to support these instructions natively.

    • runqemu:

      • The script can now run compressed images with snapshot mode. For example, with IMAGE_FSTYPES containing ext4.zst, you can run:

        runqemu snapshot ext4.zst <image-recipe>

      • Add support for the erofs filesystem.

      • The BitBake environment is now a requirement, and the script cannot run without a successful call to bitbake -e.

        The script will also raise an error with the bitbake command is not found.

  • Documentation changes:

  • Core library changes:

    • Add license_finder.py, which was extracted from recipetool to be shared for multiple users. Improve its functionalities.

  • Go changes:

  • Rust changes:

    • rust-llvm:

      • Compile LLVM to use dynamic libraries. This reduces the size of llvm-rust to about a third.

      • Disable the following feature through configuration (do_configure): libedit, benchmarks.

    • Add the has-thread-local option to the rust-target-config class.

  • Wic Image Creator changes:

    • After a Python upgrade, WIC plugins containing dashes (-) for their filenames are no longer supported. One must convert the dashed to underscores (_) and update users of the plugins accordingly.

      See the Wic plugins containing dashes should be renamed section of the Yocto Project 5.3 Migration Guide for more information.

    • wic: do not ignore IMAGE_ROOTFS_SIZE if the Rootfs is modified.

    • Several improvements in WIC selftests.

    • bootimg_efi.py: fail build if no binaries are installed.

    • Add new options to the wic ls, cp, rm, and write commands:

      • --image-name: name of the image to use the artifacts from.

      • --vars: directory with <image>.env files that store BitBake variables. This directory is usually found in STAGING_DIR.

    • Add the Wic-specific option --extra-partition-space to add extra empty space after the space filled by the filesystem in the partition.

    • The Wic-specific option --extra-space has a new alias --extra-filesystem-space.

    • bootimg_pcbios: move Syslinux install into separate functions, to make it easier to add new bootloaders.

      The Grub bootloader can now be installed with this Wic plugin.

    • Add the Wic plugin extra_partition to install files from the DEPLOY_DIR_IMAGE directory into an extra non-rootfs partition. See the IMAGE_EXTRA_PARTITION_FILES variable for more information.

  • SDK-related changes:

    • Include additional information about Meson setting in the SDK environment setup script (host system, CPU family, etc.).

    • Add Go to SDK_TOOLCHAIN_LANGS, except for the following architecture on which this is not supported:

      • RISC-V 32 bits (rv32)

      • PowerPC

    • Image-based SDKs can now include Zsh completions by adding the zsh-completion-pkgs feature to the IMAGE_FEATURES variable in the image recipe.

  • Testing-related changes:

    • bitbake/tests/fetch: Add tests for gitsm with git-lfs.

    • bitbake/lib/bb/tests/fetch: add a test case to ensure Git shallow fetch works for tag containing slashes.

    • testexport: capture all tests and data from all layers (instead of the OpenEmbedded-Core (OE-Core) layer only).

    • OEQA:

      • SDK:

        • Add a test to sanity check that the generated SDK manifest was parsed correctly and isn’t empty.

        • Add a test to verify the manifests are generated correctly.

        • Add helpers to check for and install packages.

        • Add check that meson has detected the target correctly.

      • Simplify test specification and discovery:

        • Introduce the TESTSDK_CASE_DIRS variable to specify test directory types, replacing the need to modify the default_cases class member.

        • Discover tests from configured layers using a common discovery pattern (<LAYER_DIR>/lib/oeqa/<dirname>/cases) where <dirname> is specified in TESTSDK_CASE_DIRS.

        • The “buildtools” directories were renamed to follow the common discovery pattern (<LAYER_DIR>/lib/oeqa/<dirname>/cases) for consistency across all SDK configurations.

      • selftest/reproducible: Limit memory used by diffoscope to avoid triggering OOM kills.

      • Add tests for the devicetree class.

      • Tests for the kernel-fit-image class have been reworked and improved.

      • data.py: add skipIfNotBuildArch decorator, to skip tests if BUILD_ARCH is not in present in the specified tuple.

      • selftest: add new test for toolchain switching.

      • utils/command: add a fast-path get_bb_var() that uses bitbake-getvar instead of bitbake -e when there is not postconfig argument passed.

      • core/case: add file exists assertion test case.

      • context.py: use TEST_SUITES if set.

      • runqemu: add new test for booting compressed images.

      • General improvements of the parallelization of tests, namely fixing some tests that could spawn an unlimited number of threads leading to OOM kills.

      • A new SDK test is now running for Go after go was added to SDK_TOOLCHAIN_LANGS.

      • Commands sent over SSH (using the OESSHTarget class) will now error when an SSH failure occurs. It is possible to ignore these errors by passing ignore_ssh_fails when executing a command.

  • Utility script changes:

    • sstate-cache-management: add a --dry-run argument

    • yocto-check-layer:

      • Expect success for test_patches_upstream_status. This means that patch files must include an Upstream-Status to pass with this script.

      • Show the DISTRO used when running the script.

      • yocto-check-layer class:

        • Refactor to be extended easily.

        • Add a check_network_flag test that checks that no tasks other than do_fetch can access the network.

    • send-error-report:

      • Respect URL scheme in server name if it exists.

      • Drop --no-ssl as the server URL specifies it with http:// or https://.

    • buildstats.py:

      • Extend disk stats support for NVMe and flexible token count.

      • Add tracking of network I/O per interface.

    • buildstats-diff: find last two Buildstats files if none are specified.

    • pybootchartgui:

      • visualize /proc/net/dev network stats in graphs.

      • account for network statistics when calculating extents.

  • Packaging changes:

    • Export debugsources in PKGDESTWORK as JSON. The source information used during packaging can be use from other tasks to have more detailed information on the files used during the compilation and improve SPDX accuracy.

    • When using the ipk and rpm package managers, give out more possible reasons about unmatched packages.

      For example:

      E: Package 'catch2' has no installation candidate
catch2 is a recipe. Its generated packages are: ['catch2-src', 'catch2-dbg', 'catch2-staticdev', 'catch2-dev', 'catch2-doc']
Either specify a generated package or set ALLOW_EMPTY:${PN} = "1" in catch2 recipe

    • package.py: replace all files unconditionally when copying debug sources (passing -u to the cpio command in copydebugsources()). This improves reproducibility.

  • LLVM related changes:

    • Like gcc-source, the LLVM project sources are part of work-shared under TMPDIR. The project codebase is large and sharing it offers performance improvements.

  • SPDX-related changes:

    • spdx30: Provide software_packageUrl field

    • spdx30_tasks: Change recipe license to “declared” (instead of “concluded”)

    • create-spdx-2.2: support to override the version of a package in SPDX 2 through SPDX_PACKAGE_VERSION.

  • devtool and recipetool changes:

    • Use lib/oe/license_finder to extract the license from source code.

    • Calculate source paths relative to UNPACKDIR.

    • Allow recipe create handlers to specify bitbake tasks to run.

    • create_go: Use go-mod class instead of go-vendor.

    • Go recipes are now generated with help of the new go-mod-update-modules class.

    • Add a new improve_kernel_cve_report.py script in scripts/contrib for post-processing of kernel CVE data.

    • Handle workspaces for multiconfig.

    • Fix upgrade for recipes with Git submodules.

  • Patchtest-related changes:

    • Multiple improvements to the tool’s README.

    • Don’t match BitBake Python expansions as GitHub usernames (${@...} syntax).

  • Security changes:

    • openssl: add FIPS support. This can be enabled through the fips PACKAGECONFIG.

  • cve-check class changes:

    • cve-update-db-native: FKIE: use Secondary metric if there is no Primary metric.

  • New PACKAGECONFIG options for individual recipes:

    • ppp: l2tp, pptp

    • dropbear: x11 (renamed from enable-x11-forwarding)

    • gdb: source-highlight

    • gstreamer1.0-plugins-bad: analytics

    • mtd-utils: ubihealthd-service

    • openssl: fips

    • qemu: sdl-image, pixman

    • wget: pcre2

    • mesa: asahi, amd, svga, teflon, nouveau, xmlconfig

    • dbus: traditional-activation, message-bus

    • cmake: debugger

    • freetype: brotli

    • gawk: pma-if-64bit

    • x264: ffmpeg, opencl

  • Systemd related changes:

    • Enable getty generator by default by adding serial-getty-generator to PACKAGECONFIG.

    • Now uses the USE_NLS variable to enable or disable building translations.

    • Fix deduplicated templates and instance lines in preset files when listing both template and instances in SYSTEMD_SERVICE.

    • Stop enabling non-standard MAC policy when using the ‘pni-names’ feature (part of DISTRO_FEATURES). Instead, follow what is provided by upstream systemd.

    • Install systemd-sysv-install when using the systemd-systemctl-native recipe.

  • sanity class changes:

    • insane: Move test for invalid PACKAGECONFIG to do_recipe_qa.

    • Add unimplemented-ptest detection for cargo-based tests, allowing to detect when a cargo package has available tests that could be enable with Ptest.

    • Add a test for recipe naming/class mismatches.

    • Add a sanity test for “bad” gcc installs on Ubuntu 24.04. The host should install libstdc++-14-dev instead of libgcc-14-dev to avoid build issues when building native with Clang.

    • Drop the var-undefined QA check as it was not relevant for the variables it was checking, as those are mandatory by default.

  • U-boot related changes:

    • uboot-sign: Add support for setting firmware property in FIT configuration with UBOOT_FIT_CONF_FIRMWARE.

    • uboot-sign: Add support for signing U-Boot FIT image without an SPL. The SPL_DTB_BINARY variable can be set to an empty string to indicate that no SPL is present.

    • When built for the RISC-V architecture, read the TUNE_FEATURES variable to automatically set U-boot configuration options (for example CONFIG_RISCV_ISA_F).

    • Improve the way build directories are split when having multiple configurations listed in UBOOT_CONFIG. This fixes an issue where two or more of these configurations were using the same directory for building (because these were using the same defconfig file).

  • Miscellaneous changes:

    • dropbear: The dropbearkey.service can now take extra arguments for key generation, through /etc/default/dropbear.

    • initscripts: add log_success_msg/log_failure_msg/log_warning_msg functions for logging in initscripts.

    • connman:

      • Mark iptables and nftables feature of PACKAGECONFIG mutually incompatible.

      • Set dns-backend automatically to systemd-resolved when systemd-resolved is part of DISTRO_FEATURES.

    • uninative: show errors if installing fails.

    • meson: Allow user to override setup command options by exporting MESON_SETUP_OPTS in a recipe.

    • cmake: Enhance to emit a native toolchain CMake file. This is part of improvements allowing to use clang in an SDK.

    • Fix the runtime version of several recipes (they now return the effective version instead of a default string like “Unknown”).

    • module: add KBUILD_EXTRA_SYMBOLS to the install command.

    • rpm-sequoia: add Ptest support.

    • libunwind: disable installation of tests directory with --disable-tests, which can be installed with the libunwind-ptest package instead.

    • boost: add process library to the list of built libraries.

    • base-files: add nsswitch-resolved.conf, only installed if systemd and systemd-resolved is part of DISTRO_FEATURES.

    • nfs-utils: don’t use signals to shut down the NFS server in the associated initscript, instead use rpc.nfsd 0.

    • readline: enable HOME, END, INSERT, and DELETE key bindings in inputrc.

    • Switch to a new sstate-cache CDN (http://sstate.yoctoproject.org).

    • sstate: Apply a proper umask when fetching from SSTATE_MIRRORS.

    • kernel-devsrc: make package version consistent with kernel source (by inheriting kernelsrc).

    • externalsrc: Always ask Git for location of .git directory (may be different from the default ${S}/.git).

    • features_check: Add support for REQUIRED_TUNE_FEATURES.

    • openssh: limit read access to sshd_config file (set its filemode to 0600).

    • barebox-tools now installs the rk-usb-loader utility.

    • The setuptools3_legacy class now supports the pep517-backend QA check.

    • The ccache class now supports using Ccache for native recipes when the local build configuration contains:

      ASSUME_PROVIDED += "ccache-native"
HOSTTOOLS += "ccache"

    • python_pep517: use pyproject-build instead of calling the module with nativepython3.

    • dbus-glib: include the binding tools separately into the ${PN}-tools package.

    • dbus: use the systemd class to handle the unit files of D-Bus.

    • dpkg: add ptest support.

    • shared-mime-info: Now uses the USE_NLS variable to enable building translations.

    • p11-kit: Now uses the USE_NLS variable to enable building translations.

    • babeltrace2: Enable Python plugins

    • initramfs-framework: mount a temporary filesystem on /run and move it to the root filesystem directory before calling switch_root.

    • python3: Pass PLATFORM_TRIPLET explicitly when cross compiling to make the build deterministic instead of letting Python detect the platform triplet (${HOST_ARCH}-${HOST_OS}).

    • pulseaudio: Add the audio group explicitly if pulseaudio-server is used.

    • oe/license_finder: Add find_licenses_up function to find licenses upwards until reaching a predefined top directory (as an argument).

    • mesa:

      • Build Mesa’s Asahi tools when asahi is part of the recipe’s PACKAGECONFIG variable.

      • The mesa recipe now declares two new PROVIDES for Vulkan and OpenCL ICD. These virtual provider are respectively named virtual-opencl-icd and virtual-vulkan-icd.

    • mesa-demos: split info tools to a separate package mesa-demos-info.

    • vte: skip gobject-introspection with Clang on Arm, as it caused build failures.

    • shadow: Increase the maximum group name length from 24 to 32 (default value provided by upstream recipe, was previously hardcoded to 24).

    • udev-extraconf: Speed up the mount.sh script by passing the block device of interest to blkid when getting partition label names.

    • piglit: enable OpenCL support if opencl is part of the DISTRO features.
