Merging TranslateReturnCode into wolfSSL_LastError dropped the
IP_SOCK_getsockopt(SO_ERROR) lookup emNET integrations need to retrieve
the canonical IP_ERR_* for a failed recv/send, leaving a broken branch
that returned the raw value and mishandled the POSIX-facade convention.
Restore the historic lookup (fixing the optlen pointer-vs-int typo
along the way) and add a CI test that builds wolfSSL with
-DWOLFSSL_EMNET against a clean-room shim providing an emNET-faithful
IP_SOCK_getsockopt (SO_ERROR-then-errno fallback, since Linux does not
stash EAGAIN in SO_ERROR); recv/send fall through to glibc.
The emNET `wolfSSL_LastError` branches were incorrect. The second one
was never hit and would never compile. The first one inverts error codes
that should not be inverted.
This fixes that code and adds a test with a shim layer to test emNET
calls without using emNET.
* configure.ac: --enable-dtls13 auto-enables --enable-dtls and TLS 1.3,
with a targeted error if either is explicitly --disabled, plus a
post-finalization sanity check that errors out if a later
prerequisite test forces ENABLED_TLS13 back to "no" while
ENABLED_DTLS13 is yes.
* src/internal.c, src/wolfio.c, wolfssl/wolfio.h: new WOLFSSL_DTLS_ONLY
compile-time flag elides the EmbedReceive / EmbedSend default
callbacks. The DTLS_MAJOR runtime check stays in SetSSL_CTX so a
TLS-method ctx in a DTLS-only build doesn't get datagram callbacks
by default, and WriteSEQ keeps its ssl->options.dtls branch. A
#error in settings.h refuses WOLFSSL_DTLS_ONLY without WOLFSSL_DTLS.
* wolfcrypt/src/aes.c: add HAVE_AES_DECRYPT to the inv_col_mul
definition gate to match its only caller; without it the function is
emitted dead under WOLFSSL_AES_DIRECT && NO_AES_DECRYPT and
-Werror=unused-function fails the build.
* .github/workflows/os-check.yml: matrix entry for a minimal DTLS 1.3
client-only build.
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.
Reduce the number of tests running on macos in os-check.yml to the
minimum required number to cover all mac os specific features. All other
platform-agnostic configs and setups are only tested on Linux, which is
much faster in GitHub CI.
.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.

Add SRAM PUF (Physically Unclonable Function) support to wolfCrypt. Derives device-unique cryptographic keys from the power-on state of SRAM memory using a BCH(127,64,t=10) fuzzy extractor with HKDF key derivation.
- **wolfCrypt PUF API** (`wolfcrypt/src/puf.c`, `wolfssl/wolfcrypt/puf.h`)
- `wc_PufInit`, `wc_PufReadSram`, `wc_PufEnroll`, `wc_PufReconstruct`
- `wc_PufDeriveKey` (HKDF-SHA256), `wc_PufGetIdentity` (SHA-256 device fingerprint)
- `wc_PufZeroize` (secure context cleanup)
- `wc_PufSetTestData` (synthetic SRAM for testing without hardware)
- **BCH(127,64,t=10) error-correcting codec** - corrects up to 10 bit flips per 127-bit codeword across 16 codewords
- **`WC_PUF_SHA3` build option** - select SHA3-256 instead of SHA-256 for identity hash and HKDF (default: SHA-256)
- **Precomputed GF(2^7) tables** - `const` arrays in `.rodata` (no runtime init, thread-safe, flash-resident on embedded)
- `./configure --enable-puf` (auto-enables HKDF dependency)
- CMake: `WOLFSSL_PUF=yes`
- `WOLFSSL_USER_SETTINGS`: define `WOLFSSL_PUF` and `WOLFSSL_PUF_SRAM`
- See wolfssl-examples/puf for example implementation on STM32 NUCLEO-H563ZI (Cortex-M33, STM32H563ZI)
- Supports test mode (synthetic SRAM)
- Builds to ~13KB `.elf`
- Tested on NUCLEO-H563ZI: enrollment, noisy reconstruction, key derivation all pass
- `.github/workflows/puf.yml`: host build + test workflow for PUF feature
- Doxygen API docs for all 8 public functions
- PUF group added to `doxygen_groups.h`
Implement RFC8773bis (draft-ietf-tls-8773bis-13)
cert_with_extern_psk for TLS 1.3, including protocol checks
and API support.
Includes unit tests for API and handshake behavior as well
as tests in the testsuite using extended examples.
