The function _fp_exptmod_nct() is using WOLFSSL_NO_MALLOC to guard
using stack allocation vs malloc. It's twin function _fp_exptmod_ct()
is using WOLFSSL_SMALL_STACK for this. This is causing inappropriate use
of malloc() in a small stack environment. The no-malloc case will also
be kept so static memory and no-malloc fix still works.
1. Change the guards for `#ifndef WOLFSSL_NO_MALLOC` in the function
`_fp_exptmod_nct()` to `#if defined(WOLFSSL_SMALL_STACK) &&
!defined(WOLFSSL_NO_MALLOC)`.
* set DEFAULT_ENABLED_ALL_ASM=no if enable_afalg or ENABLED_32BIT;
* omit enable_srtp_kdf from enable-all-crypto if enable_afalg.
linuxkm: add GetCAByAKID to wolfssl_linuxkm_pie_redirect_table.
src/x509.c: in GenerateDNSEntryIPString(), use XMEMSET() to initialize tmpName, not = {0}, to avoid unmaskable compiler emission of memset() call.
wolfssl/openssl/ssl.h: add OPENSSL_EXTRA to an existing OPENSSL_ALL-gated section, consistent with gating of correspinding section in wolfssl/ssl.h.
wolfssl/wolfcrypt/settings.h: adopt setup for WOLFSSL_SP_NO_UMAAL from wolfssl/wolfcrypt/sp_int.h now that it's used by wolfcrypt/src/port/arm/thumb2-poly1305-asm.S.
* Proposed new interface for AesSivEncrypt with number of ADs != 1.
* Implement AES SIV S2V computation with a number of ADs not equal to 1.
* Add Example A.1 from RFC5297 to AES SIV test vectors.
* Add tests for new AES SIV interface, and add test vectors for examples given in RFC5297.
* Include the nonce in count of maximum number of ADs.
* Addressing review comments.
* Addressing review comments: Use uppercase 'U' suffix on unsigned constant.
* Rename local variables named 'ad0' to 'ad', since the zero makes no sense, especially since in the RFC 5297 document they're actually counting the ADs from 1.
* adds wc_DhAgree_ct().
* adds wolfSSL_DH_compute_key_padded(), using wc_DhAgree_ct() if available, with fallback fixup code.
* adds unit test coverage in api.c:test_wolfSSL_DH() for expected-success calls to wolfSSL_DH_compute_key() and wolfSSL_DH_compute_key_padded().
* fix TLS layer to consistently use WOLFSSL_FATAL_ERROR for error retvals, rather than literal -1.
* add WC_NO_ERR_TRACE() wrapper around LENGTH_ONLY_E (it does not signify an error condition).
* refactor errcode handling for traceability in wolfSSL_DSA_do_sign(), wolfSSL_DH_size(), wolfSSL_EC_KEY_get_conv_form(), wolfSSL_d2i_DSA_SIG(), wolfSSL_DSA_do_sign(), SetDhInternal(), and wolfSSL_EC_KEY_get_conv_form().
kdf.c: wc_PRF() - No need for previous, reuse current.
sha256.c: Transform_Sha256() - Add slow but small version for many
register implementation.
sp_int.h: Change 'used' and 'size' fields to 16-bit types when possible.
sp_int.c: Fixes for 16-bit used.
