The 10 GB, LRU-evicted, PR-scoped Actions cache was being thrashed - the
docker simulator buildx layers (~6 GiB), plus per-PR ccache and apt-archive
writes whose keys never hit - which kept evicting the shared ccache, while
the apt mirror timed out often enough to break PR CI. Move the heavy caches
to ghcr (free, separate pool) and make PR runs read-only against the Actions
cache.
apt dependencies from prebuilt ghcr .deb bundles
- ci-deps-image.yml resolves each package list under .github/ci-deps/ into
its .deb closure and publishes ghcr.io/<owner>/wolfssl-ci-debs:<tag> in
two tiers: <ver>-minimal (make-check family) and <ver>-full (interop
superset), for ubuntu-22.04 and 24.04.
- install-apt-deps gains a ghcr-debs-tag input: pull the bundle and install
offline (--no-download) so the apt mirror is never on the PR critical
path. Any failure (bundle missing/not public/incomplete) falls through to
the existing apt path, so it is always safe to set.
sim-test buildx layers to a shared ghcr registry cache
- the 7 docker simulator workflows switch from cache-to: type=gha to
ghcr.io/wolfssl/wolfssl-sim-cache:<scope>. cache-from reads on every run
(anonymous); cache-to writes only on the weekend cron and manual
workflow_dispatch. Per-distinct-image tags and de-duplicated writers keep
parallel matrix jobs from racing on one ref.
ccache: PRs read, the schedule writes
- ccache-setup gains read-only: PR runs restore the shared master-scoped
cache but never upload; schedule/push runs refresh it. Wired across
os-check (linux + macOS), pq-all, smoke-test and the 12 small make-check
workflows.
- parallel-make-check.py gains --build-only (compile every config, skip the
test phase) so weekday-morning seed crons warm the cache PR runs consume.
artifact retention capped at 7 days on the failure-log/result uploads that
previously defaulted to 90.
ONE-TIME SETUP: after their first publish, make the ghcr packages
wolfssl-ci-debs and wolfssl-sim-cache PUBLIC so anonymous pulls work from PR
(including fork) runs; until then everything falls back cleanly.
GitHub Actions now emits "Node.js 20 actions are deprecated" warnings:
actions are forced to Node.js 24 by default starting 2026-06-16, and
Node.js 20 is removed from the runners on 2026-09-16. Update every
JavaScript action referenced by the workflows and the local composite
actions to the lowest release that runs on Node.js 24:
actions/checkout v4 -> v5
actions/checkout (SHA pin) v4.1.7 -> v5
actions/upload-artifact v4 -> v6 (v5 still Node.js 20)
actions/download-artifact v4 -> v7 (v5/v6 still Node.js 20)
actions/cache[/restore|/save] v4 -> v5
actions/setup-python v5 -> v6
actions/github-script v7 -> v8
docker/setup-buildx-action v3 -> v4
docker/build-push-action v5 -> v7 (v6 still Node.js 20)
docker/login-action v3 -> v4
microsoft/setup-msbuild v2 -> v3
open-watcom/setup-watcom v0 -> v1
Actions already running on Node.js 24 (jwlawson/actions-setup-cmake,
shogo82148/actions-setup-perl, msys2/setup-msys2, dorny/paths-filter)
are left unchanged. These bumps are runtime-only; no workflow uses an
input or output removed by the new majors, and v4-format artifacts
remain compatible across the upload v6 / download v7 backends.
Replace the one-runner-per-configuration matrices across the
make-check workflow family with a generic pooled runner,
.github/scripts/parallel-make-check.py. Each workflow keeps its
configuration list as JSON next to the invocation; one runner (or a
small fixed set of shards, balanced by measured per-config minutes)
builds every config in its own out-of-tree (VPATH) build directory off
a single checkout/autogen, on a pool of one-per-CPU worker threads,
longest first. Concurrent checks are isolated with bubblewrap network
namespaces, compilations are cached with ccache, the first failure
aborts the rest (fail-fast, with --no-fail-fast to run everything),
and per-config timings plus pool efficiency land in the step summary.
Failure logs upload as artifacts. smoke-test.yml is likewise reworked
into a single pooled job that runs its nine configs on one runner.
Converted workflows (runner jobs per full pass):
os-check.yml 101 -> 8 (92 Ubuntu configs -> 4 shards;
the macOS matrix, the user-settings jobs and
the standalone
macos-apple-native-cert-validation.yml fold
into one macOS runner; Windows unchanged)
pq-all.yml 21 -> 2 shards
disable-pk-algs.yml 15 -> 1
wolfCrypt-Wconversion.yml 11 -> 1
trackmemory.yml 7 -> 1
cryptocb-only.yml 8 -> 1 (incl. the two new SHA512 entries)
multi-compiler.yml 6 -> 1
smallStackSize.yml 6 -> 1
multi-arch.yml 6 -> 1
async.yml 5 -> 1
psk.yml 5 -> 1
no-malloc.yml 3 -> 1
wolfsm.yml 3 -> 1
opensslcoexist.yml 2 -> 1
Measured against current upstream passing runs (job execution time,
queue excluded): ~200 runner jobs / ~374 runner-minutes per full pass
become 23 jobs / ~168 runner-minutes, with more coverage than before.
multi-arch's old matrix combined an "include" list of four
architectures with an "opts" axis; GitHub's include-merge rules made
each arch entry overwrite the previous one, so only the armel
combinations actually ran. The pooled list restores the intended
aarch64/armhf/riscv64 coverage (23 combinations; riscv64 x sp-math is
omitted as invalid - configure rejects sp-math without SP, and
--enable-riscv-asm, unlike --enable-sp-asm, does not bring SP in).
Out-of-tree build fixes this depends on:
- Makefile.am: symlink the read-only test data (certs/, tests/ config
files, sniffer captures and helpers, examples/crypto_policies,
input, quit) into the build tree via a BUILT_SOURCES stamp, removed
again in distclean-local. ChangeToWolfRoot() and the script tests
resolve everything relative to the working directory, so out-of-tree
make check and make distcheck now pass.
- scripts/multi-msg-record.py: locate the client binary from the build
tree working directory rather than the script's source directory.
- configure.ac + wolfssl/include.am: run
support/gen-debug-trace-error-codes.sh from $srcdir; it reads the
error-code headers from the source tree and generates into the build
tree.
- tests/swdev: a WOLFBUILD variable points the sub-make at the build
tree for the configure-generated headers (wolfssl/options.h,
wolfssl/version.h); the in-tree-only guards are dropped.
Portions of PR #10649 are incorporated: the cross-platform
ccache-setup composite action, repository_owner gates on check-headers
and check-source-text, the docs-only paths-ignore on os-check, and the
libspdm timeout bumps.
Increase the timeout for PQC CI tests from 6 to 10 minutes. The new
SLH-DSA tests take more time than the previous tests due to the slow
signing. With the old timeout, some tests sometimes hit the timeout
before finishing successfully.
.github/workflows/pq-all.yml: for the --enable-sp-math scenario, --disable-quic (QUIC unit tests fail on that combo);
wolfcrypt/test/test.c: add WC_MAYBE_UNUSED to ecdsa_test_deterministic_k_rs(), to fix armel sp-math build.
* add "-Wnull-dereference" to all existing "-pedantic -Wdeclaration-after-statement" configs;
* add an --enable-sp-math config to .github/workflows/pq-all.yml and .github/workflows/multi-arch.yml.
This update introduces the WOLFSSL_DILITHIUM_DYNAMIC_KEYS option, allowing
for dynamic memory allocation of public and private key buffers. This change
reduces memory usage by allocating buffers only when needed.
Introduce the WOLFSSL_MLKEM_DYNAMIC_KEYS option to allow dynamic allocation
of private and public key buffers in the MlKemKey struct. This change
enables right-sizing of buffers based on the actual ML-KEM level and eliminates
unnecessary memory usage for encapsulate-only operations.
* Enable ML-KEM by default in build systems (autoconf and CMake)
* Only allow three to-be-standardized hybrid PQ/T combinations by
default
* Use X25519MLKEM768 as the default KeyShare in the ClientHello (if user
does not override that). When Curve25519 is disabled, then either
WOLFSSL_SECP384R1MLKEM1024 or WOLFSSL_SECP256R1MLKEM768 is used as
default depending on the ECC configuration
* Disable standalone ML-KEM in supported groups by default (enable with
--enable-tls-mlkem-standalone)
* Disable extra OQS-based hybrid PQ/T curves by default and gate
behind --enable-experimental (enable with --enable-extra-pqc-hybrids)
* Reorder the SupportedGroups extension to reflect the preferences
* Reorder the preferredGroup array to also reflect the same preferences
* Add async support for ML-KEM hybrids
* More PQC configurations
* More CMake setups
* Fix various bugs uncovered by these tests
Added some missing feature additions to CMake to make the example
`user_settings_all.` config file work for the CI test.
refactor all static flag initializations to use cpuid_get_flags_ex() for race-free dynamics;
refactor cpuid_set_flags() to be race-free;

wolfcrypt/test/test.c: add to memory_test() tests for all atomic macros and APIs;
.github/workflows/pq-all.yml: don't use -Wpedantic for CC=c++ scenario.
-Wdeclaration-after-statement to .github/workflows/pq-all.yml.
rearrange code/gating in wolfcrypt/src/wc_mlkem.c:mlkemkey_encapsulate() for
clarity and to fix a -Wdeclaration-after-statement.
also, made mlkem_encapsulate_c() and mlkem_encapsulate() return error code
(currently always zero) rather than void, for consistency.
configure.ac: fix Kyber/ML-KEM option setup.
ML-KEM/Kyber:
MakeKey call generate random once only for all data.
Allow MakeKey/Encapsulate/Decapsulate to be compiled separately.
Pull out public key decoding common to public and private key decode.
Put references to FIPS 140-3 into code. Rename variables to match FIPS
140-3.
Fix InvNTT assembly code for x64 - more reductions.
Split out ML-KEM/Kyber tests from api.c.
TLSX:
Store the object instead of the private key when WOLFSSL_MLKEM_CACHE_A
is defined or WOLFSSL_TLSX_PQC_MLKEM_STORE_OBJ. Faster decapsulation
when A is cached and object stored.
To store private key as normal define
WOLFSSL_TLSX_PQC_MLKEM_STORE_PRIV_KEY.
