* add --enable-wolfentropy as a synonym for --enable-wolfEntropy;
* avoid -Wno-deprecated-enum-enum-conversion when KERNEL_MODE_DEFAULTS, to work around old gcc with broken results from AX_CHECK_COMPILE_FLAG();
* rework help messages for several synonym options to refer to the canonical option (--enable-linuxkm-pie, --enable-kyber, --enable-dilithium, --enable-amdrand, --enable-entropy-memues).
### `wolfssl/internal.h`
- **`InternalTicket` struct gains a flexible array member**: A new `peerCert[]` field (with a preceding `peerCertLen[2]`) is added to `InternalTicket`. This allows the peer's DER-encoded certificate to be stored directly inside the session ticket.
- **`ExternalTicket` struct becomes variable-length**: The `enc_ticket` field is changed from a fixed-size array to a flexible array member (`byte enc_ticket[]`). The `mac` field is removed from the struct — the MAC is now placed dynamically after the encrypted data in `enc_ticket`.
### `src/internal.c`
- The `GetRecordHeader` function now only adds `MAX_COMP_EXTRA` to the maximum allowed record size when `ssl->options.usingCompression` is true, tightening the length validation. The max fragment length extension check is now much stricter.
- **Peer certificate is serialized into the ticket**: During ticket creation, the code attempts to find the peer certificate from `ssl->peerCert` or from `ssl->session->chain` (fallback). If found and within `MAX_TICKET_PEER_CERT_SZ`, it's copied into `it->peerCert`. DTLS is explicitly excluded (peer cert length set to 0) to keep ticket size small for MTU constraints. If `HAVE_MAX_FRAGMENT` is defined and max fragment is not `MAX_RECORD_SIZE` for TLS 1.3, the cert is also skipped since `SendTls13NewSessionTicket` doesn't support fragmentation yet.
- **Peer certificate restoration from ticket**: On successful ticket decryption, if the ticket contains a peer certificate (`peerCertLen > 0`), it is decoded back into `ssl->peerCert` via `ParseCertRelative`/`CopyDecodedToX509`, and also added to `ssl->session->chain` via `AddSessionCertToChain`.
- The `CLEAR_ASN_NO_PEM_HEADER_ERROR` macro was rewritten to loop and remove all consecutive PEM no-start-line errors (not just the last one), wrapped in a `do { ... } while(0)` for safety.
- The `SendTicket` function is simplified to use `SendHandshakeMsg` to support fragmenting the larger ticket.
---
### `src/x509.c`
- `loadX509orX509REQFromPemBio` now accepts `TRUSTED_CERT_TYPE` in addition to `CERT_TYPE` and `CERTREQ_TYPE`.
- **Streaming BIO support**: When `wolfSSL_BIO_get_len()` returns ≤ 0 (e.g., pipes/FIFOs), the function no longer returns an error. Instead, it sets an initial buffer of `MAX_X509_SIZE` and dynamically grows (doubling) up to `MAX_BIO_READ_BUFFER` (`MAX_X509_SIZE * 16`) as data is read byte-by-byte.
- **Alternate footer detection**: For `TRUSTED_CERT_TYPE`, the PEM reader also checks for the regular `CERT_TYPE` footer (`-----END CERTIFICATE-----`) in addition to the trusted cert footer (`-----END TRUSTED CERTIFICATE-----`), so it can parse either format.
- Removed two lines that set `cert->srcIdx` to `SIGALGO_SEQ` offset. This makes `cert->srcIdx` reflect the end of parsed certificate data. This is used by `loadX509orX509REQFromBuffer` to detect where auxiliary trust data begins in trusted certificates.
---
### `src/ssl_sk.c`
- Added a `STACK_TYPE_X509_CRL` case to `wolfssl_sk_dup_data` that calls `wolfSSL_X509_CRL_dup` for deep-copying CRL stack elements. Previously, `STACK_TYPE_X509_CRL` fell through to the unsupported default case.
---
### `wolfssl/openssl/ssl.h`
- `sk_X509_dup` now maps to `wolfSSL_shallow_sk_dup` (was `wolfSSL_sk_dup`/deep copy). This matches OpenSSL's behavior where `sk_X509_dup` does a shallow copy.
- `sk_SSL_CIPHER_dup` similarly changed to `wolfSSL_shallow_sk_dup`.
---
### `src/ssl_api_cert.c`
- When `ssl->ourCert` is `NULL` and the SSL owns its cert, the function now checks if `ssl->ctx->ourCert` points to the same certificate (by comparing DER buffers). If so, it returns the ctx's `X509` pointer directly. This maintains pointer compatibility for applications (like nginx OCSP stapling) that use the `X509*` from `SSL_CTX_use_certificate` as a lookup key.
### `src/bio.c`
- When `wolfssl_file_len` returns `WOLFSSL_BAD_FILETYPE` (now returned for pipes/FIFOs), `wolfSSL_BIO_get_len` treats it as length 0 instead of propagating the error.
---
### `tests/test-maxfrag.conf` and `tests/test-maxfrag-dtls.conf`
- Removed `DHE-RSA-AES256-GCM-SHA384` test entries because the ClientKeyExchange doesn't fit in the selected max fragment length.

## Summary
- Add non-blocking (incremental) Curve25519 key generation and shared secret via `WC_X25519_NONBLOCK`, modeled after the existing ECC non-blocking pattern (`WC_ECC_NONBLOCK`)
- Implement `curve25519_nb()` and `fe_inv__distinct_nb()` in `fe_low_mem.c` as state-machine variants that return `FP_WOULDBLOCK` to yield after each field multiply
- Add `wc_curve25519_set_nonblock()` API to attach/detach non-blocking context to a key
- Integrate X25519 non-blocking with TLS 1.2/1.3 key share generation and shared secret in `tls.c` and `internal.c` (behind `WC_X25519_NONBLOCK && WOLFSSL_ASYNC_CRYPT_SW`)
- Add `--enable-curve25519=nonblock` configure option (auto-enables `--enable-asynccrypt` and `--enable-asynccrypt-sw`)
- Add X25519 async software dispatch cases in `async.c` and types in `async.h`
- Fix async guard in `curve25519.c` to require `WOLFSSL_ASYNC_CRYPT_SW` (matching other algorithms)
- Overhaul `examples/async/` client/server: non-blocking I/O via `WOLFSSL_USER_IO`, standalone `Makefile`, X25519/ECC mode selection, CI-friendly ready-file sync
- Add `examples/configs/user_settings_curve25519nonblock.h` and CI coverage in `os-check.yml` and new `async-examples.yml` workflow
- Add wolfcrypt test and API test coverage for X25519 non-blocking
* Minor fixes to the CMakeLists.txt
* Add more options to the CMake infrastructure already present in the
autoconf infrastructure
* An autoconf build now also generates and installs files required to
consume the installed wolfssl library via CMake.
* Added test for autoconf-CMake interworking
Work is mostly done by Codex and Curser.
wolfssl/wolfcrypt/settings.h: classify OPENSSL_EXTRA as "desktop type system" in bump up of default FP_MAX_BITS and SP_INT_BITS;
wolfssl/wolfcrypt/types.h: if WC_32BIT_CPU, don't define WC_64BIT_CPU.
wolfcrypt/src/rng_bank.c:
* add wc_local_rng_bank_checkout_for_bankref, wc_BankRef_Release(), wc_rng_bank_new(), and wc_rng_bank_free();
* in wc_rng_bank_checkin(), take a struct wc_rng_bank_inst **rng_inst and NULL it before return;

* fix order of operations in wc_rng_bank_checkout() re DISABLE_VECTOR_REGISTERS();
wolfcrypt/src/random.c:

add various comments for clarity.
Branching to a common block encrypt/decrypt may work for assembly but
not always for C code.
Added option, for assembly and inline assembly, to inline block
encrypt/decrypt: WOLFSSL_ARMASM_AES_BLOCK_INLINE.
Add non-constant time implemenations of mod_inv for x64 and Aarch64
assembly.
Generate base point table, with better formatting, for double smul with
a script.
Increase Bi table size to 32 entries for 64-bit asm.
Minor improvements to double smul.
WOLFSSL_CURVE25519_NOT_USE_ED25519 to not use ed25519 base smul in
curve25519 base smul.
Gate keeping the seed FD open behind WOLFSSL_KEEP_RNG_SEED_FD_OPEN and only
enable by default for HAProxy. It is causing issues on OS X and may
cause issues on other OSes, and is generally a major behavior change.
Use the Ed25519 base smul in Curve25519 base mul and covert to
Montogmery curve for a faster implementation.
Only when Ed25519 is compiled in or WOLFSSL_CURVE25519_USE_ED25519 is
defined.
When compiling Intel x64 assembly and Aarch64 assembly, always define
WOLFSSL_CURVE25519_USE_ED25519.
Can't use with blinding - normal C implementation.
Optimized the Curve25519 smul slightly for Intel x64 and Aarch64.
Improved the conditional table lookup on Intel x64 to use AVX2 when
available.
globally replace defined(__PIE__) with defined(WC_CONTAINERIZE_THIS) to decouple containerization from -fPIE;
configure.ac:
* add --enable-kernel-reloc-tables as an alias for --enable-linuxkm-pie;
* always activate ENABLED_ENTROPY_MEMUSE_DEFAULT when KERNEL_MODE_DEFAULTS and not RDSEED/RDRAND, regardless of FIPS presence/version;
linuxkm/Kbuild:
* add -DWC_CONTAINERIZE_THIS to PIE_FLAGS;
* add support for NO_PIE_FLAG, which inhibits -fPIE on ENABLED_LINUXKM_PIE builds, and adds -DWC_NO_PIE_FLAG to PIE_FLAGS;
linuxkm/linuxkm_wc_port.h: add setup for WC_LINUXKM_WOLFENTROPY_IN_GLUE_LAYER;
linuxkm/module_hooks.c: add wc_linuxkm_GenerateSeed_wolfEntropy().
