Every recipe below builds sources whose headers say "or (at your
option) any later version", so none is -only.
- 15 recipes GPL-3.0-only -> GPL-3.0-or-later (wolfssl, linuxkm,
wolfcrypttest/benchmark, wolfprovider(+cmd/test), wolfengine,
wolfssh, wolfpkcs11, wolfhsm, wolfboot, wolftpm, wolfcrypt-py)
- wolfmqtt, wolfclu: GPL-2.0-only -> GPL-3.0-or-later (sources are
v3+). wolfclu checksum moved from LICENSE (GPLv2 text) to COPYING
(GPLv3 text) at the pinned rev.
- wolfssl-py, wolf-py-tests, wolftpm-wrap-test: GPL-2.0-only ->
GPL-2.0-or-later (sources at those pins are v2+).
- README: wolfSSL is GPLv3 (or later), not GPLv2.
Unchanged: fips-ready recipes (source is a user-supplied bundle) and
wolfssl-gnutls-wrapper (upstream has no license file).
update-version.sh: use the release tag from the GitHub API and report successful updates.
wolfhsm: note its version-guard patch is a no-op on 5.9.4, kept for older FIPS/commercial bundles.
Bumps SRC_URI to dgarske/wolfBoot fit_compressed and updates SRCREVs to
pull in the FIT ramdisk extraction (RAMDISK build switch +
linux,initrd-{start,end} DTB fixup) and the gzip subimage decompression
work. Required by ZynqMP boards (e.g. Gilat ZCU102) that ship the
initramfs as a separate FIT ramdisk node rather than bundling it into
the kernel image.
wolfssl SRCREV pinned to v5.9.1-stable to match what fit_compressed
points at via lib/wolfssl.
Validated end-to-end on ZCU102: FSBL -> ATF -> wolfBoot loads kernel +
ramdisk to 0x40000000, patches /chosen/linux,initrd-{start,end}, signed
image (RSA4096+SHA3-384) verifies, kernel boots and unpacks initramfs.
Add wolfBoot secure boot support to meta-wolfssl. Four new recipes
cross-compile wolfboot.elf, build host-side signing/keygen tools,
and sign kernel FIT images with RSA4096+SHA3-384 for verified boot.
New recipes:
wolfboot.inc - shared SRC_URI, LICENSE, SRCREVs
wolfboot_git.bb - cross-compiles wolfboot.elf from a
user-selected config/examples/ template;
embeds a user-supplied RSA4096 public key
wolfboot-keytools-native_git.bb - native wolfboot-keygen / wolfboot-sign
wolfboot-signed-image.bb - signs kernel FIT with RSA4096+SHA3-384
Supporting files:
xilinx-bootbin_%.bbappend - replaces U-Boot with wolfBoot in BOOT.BIN
on ZynqMP (gated by WOLFBOOT_ENABLE="1");
uses BBFILES_DYNAMIC for meta-xilinx-tools
conf/layer.conf - registers wolfboot BBFILES globs and
PREFERRED_PROVIDER
README.md - usage guide, key provisioning, ZynqMP notes
Design decisions:
- Signing key is user-supplied out-of-band (WOLFBOOT_SIGNING_KEY) to
avoid leaking private key material through sstate or DEPLOY_DIR_IMAGE.
- wolfboot_git.bb uses raw make (not oe_runmake) because wolfBoot is a
bare-metal bootloader with its own -nostdlib/-ffreestanding toolchain
flags that conflict with Yocto's CC/CFLAGS/LDFLAGS injection.
- SRCREVs use weak assignment (?=) so downstream users can override via
local.conf to track unreleased upstream fixes.
Tested on AMD/Xilinx ZCU102 hardware with PetaLinux 2025.2:
FSBL -> PMU FW -> ATF -> wolfBoot (EL2) -> signed FIT -> Linux
WOLFBOOT_CONFIG="zynqmp_sdcard.config"
WOLFBOOT_LINUX_BOOTARGS_ROOT="/dev/mmcblk0p4"
* Refactor meta-wolfssl: modularize feature enablement and centralize helpers in bbclass
Refactored layer.conf to unconditionally include all recipes, moved feature-specific configuration into modular .inc files, created wolfssl-helper.bbclass with reusable do_wolfssl_autogen and do_wolfssl_check_package tasks, updated all recipes to use the new pattern, and standardized commercial license variables to be recipe-specific.
Use a virtual wolfssl to make library switching easier for fips vs non fips or other wolfSSL packages
Set wolfssl libraries as the deafualt weak Preferred_Provider option for packages
* Merged refactor and new test changes
* Combine refactor changes and add replace default and fips modes
* Add working and tested fips, replace default, non-fips, non-replace-default work
* Add FIPS replace default to layers and test all options
* Refactor bbappends to be more yocto like
* Add overide to openssl configure
* Address comment concerns
* Only do neccesary simlinks
* Only do neccesary simlinks
* Convert wolfprovider test bbappend to inc file
* Add Image minimals for all wolfprovider modes
* Fully tested images
* Get conf files from source
* Fix FIPS package issues
* Fixes 7z extraction issues, mostly around using password when the
password has already been stripped out
* Fixes autoreconf and configure issues with the FIPS package
* Fixes wolfcrypttest and wolfcryptbenchmark not being isntalled with
FIPS when they are selected
* Fix unstable meta data for fips package
* Fix the execution command for QEMU
The execution of QEMU to get the hash would fail when cross-compiling to
a different CPU target. This fixes it.
* gnutls-wolfssl layers
Added 3 layers
- gnutls: gnutls fork patched to use wolfssl as cryptographic
provider
- wolfssl: wolfssl configured to work against gnutls
- wolfssl-gnutls-wrapper: shim layer that gets called by gnutls
applications when linked against gnutls-wolfssl
- gnutls-wolfssl-tests: tests from the wolfssl-gnutls-wrapper folder
installed under /usr/lib/wolfssl-gnutls-wrapper/
Everything gets installed under /usr ovverriding the system installed
recipes, the wrapper is symlinked in /opt.
Fips currently not supported.
* fips support
* Removed hmac generation and installation since this step is already
happening on the base recipe
* gnutls layers (from https://github.com/wolfSSL/meta-wolfssl/pull/111/)
rebased against the new staging branch (refactor-meta-wolfssl)
* - added gnutls-image-minimal;
- update layer.conf to conditionally include gnutls-image-minimal if
included in the WOLFSSL_DEMOS;
- minor update to inc/gnutls/gnutls-enable-wolfssl.inc to by pass the
fuzzing binaries from the base recipes;
* added do_configure[network] = "1" to the inc file (fixes networking issues on
some builds)
* Add support for GCP and tarballs
The commercial package can now be retrieved from GCP and can be a
tarball without password protection.
* fix stamp.h in append rather than main .bb
* Update wolfprovider include files with local changes
* Add messages for debug files
* Follow Debian convention for provider config in openssl.cnf
- Install provider*.conf files to /etc/ssl/openssl.cnf.d/ instead of /opt
- Remove OPENSSL_CONF environment variable approach
- Add .include directive to openssl.cnf automatically in explicit load mode
- This allows OpenSSL to automatically load the provider configuration
- Update script output to reflect the new approach
* Append conf fil
* Don't use fixed version for FIPS
User can use any FIPS wolfSSL package
* Fix naming for new fips rename
* Add final wolfprovider refactor changes
* Benchmark and GPG Error Patch to resolve build issues and disable benchmarking due to length of time it takes to run AES GCM in current port
* Fixes for when GNUPG is needed
* Update wolfProvider images to match other demo images,
add to bbclass to ensure configurations are not added
to reciepes automatically.
* Fips Image for reference
* Fix openssl target detection
This was not working properly on an ARM64 build.
* Add symlink in ossl-modules, install provider.conf from main module
* Remove debug for wolfprovider
* Add fix for loading conf in wolfproviderenv
* linuxkm: add non-FIPS kernel module recipe and initramfs integration class
This introduces support for building the wolfSSL Linux kernel module (linuxkm)
in non-FIPS configurations and adds a generic bbclass for including the module
in any initramfs image.
Key additions:
- New recipe: wolfssl-linuxkm.bb (non-FIPS)
* Builds linuxkm against the target kernel
* Installs libwolfssl.ko into /lib/modules/.../extra
* Adds auto-load entry under /etc/modules-load.d/
* Tracks upstream wolfSSL master at commit 3062d1524
- New class: wolfssl-initramfs.bbclass
* Allows any initramfs image to include the linuxkm module
* Intended to be inherited from BSP/distro override layers
This prepares the layer for future FIPS/non-FIPS split support and provides
a clean mechanism for systems that need early-boot availability of the
wolfSSL kernel module.
