Improve performance of CFB and OFB.
Only have one implementation that is used by OFB encrypt and decrypt.
Update AES testing in unit.test.
Update benchmarking of CFB and OFb to include decrypt.
This adds heap and stack tracking to wolfCrypt bench so that it is
possible to see RAM usage. It also adds support for stack tracking in
microcontrollers (tested on STM32).
x509.c: realloc may fail and therefore need to store result in a
temporary so the old pointer is not lost.
tls.c: free the name if it is not pushed on to the stack of peer CA
names. Failure to push can be from memory allocation failure.
aes.c: Don't compile XTS decrypt functions without HAVE_AES_DECRYPT.
Fix tests to have better pre-processor protection.
rename WOLFSSL_LINUXKM_USE_SAVE_VECTOR_REGISTERS to WOLFSSL_USE_SAVE_VECTOR_REGISTERS, and wherever appropriate, replace defined(WOLFSSL_LINUXKM) with defined(WOLFSSL_USE_SAVE_VECTOR_REGISTERS).
rename WC_WANT_FLAG_DONT_USE_AESNI to WC_WANT_FLAG_DONT_USE_VECTOR_OPS.
rename lkm_printf() to wc_km_printf().
replace WOLFSSL_LINUXKM gates on kernel-incompatible includes with header-specific gates NO_STRING_H, NO_STDINT_H, NO_LIMITS_H, NO_CTYPE_H, NO_STDLIB_H
remove low level threading setup section of wolfssl/internal.h, which duplicated existing logic in wc_port.h, except for off-topic WOLFSSL_APACHE_MYNEWT TLS-layer setup, which is preserved, and a defined(__NT__) clause, which is now merged into the existing section in wc_port.h.
add WC_GENERATE_SEED_DEFAULT, which defaults to wc_GenerateSeed if not overridden, and replace wc_GenerateSeed with WC_GENERATE_SEED_DEFAULT in various calls to wc_SetSeed_Cb();
linuxkm/linuxkm_wc_port.h: if FIPS <v6 and RDSEED, define WC_LINUXKM_RDSEED_IN_GLUE_LAYER and define WC_GENERATE_SEED_DEFAULT wc_linuxkm_GenerateSeed_IntelRD;
wolfcrypt/test/test.c: update rng_seed_test() with gating and vectors for FIPS v5 with HAVE_AMD_RDSEED or HAVE_INTEL_RDSEED;
wolfssl/wolfcrypt/types.h: add WC_HAVE_VECTOR_SPEEDUPS helper macro, and enlarge fallthrough definition coverage for DISABLE_VECTOR_REGISTERS.
Optimize code knowing it is for Intel x64.
Change signing to calculate one polynomial at a time so that if it isn't
valid then we fail early.
Other minor improvements.
Move the SHA-3 4 blocks at a time assembly into SHA-3 asm file.
Make constants in assembly the same length (front pad with zeros).
wolfcrypt/benchmark/benchmark.c:
* use WC_RELAX_LONG_LOOP() as default definition of TEST_SLEEP(), and remove WC_RELAX_LONG_LOOP() from bench_stats_sym_finish()/bench_stats_asym_finish_ex();
* when WOLFSSL_LINUXKM but !WOLFSSL_LINUXKM_USE_SAVE_VECTOR_REGISTERS., properly wrap kernel_fpu_begin...end around floating point ops.
* move enum wc_svr_flags out of BUILDING_WOLFSSL guard;
* add DISABLE_VECTOR_REGISTERS() and REENABLE_VECTOR_REGISTERS() definitions for !BUILDING_WOLFSSL;
* add #include <linux/spinlock.h> to !WOLFSSL_LINUXKM_USE_MUTEXES implementation to fix compilation (and add usability) to caller code;
linuxkm/lkcapi_sha_glue.c: in wc_linuxkm_drbg_ctx_clear(), fix error-path deallocation of locked object;
wolfcrypt/benchmark/benchmark.c:
* in FIPS v6+ builds, and FIPS linuxkm v5+, check retval from wc_AesEncryptDirect() and wc_AesDecryptDirect();
* add WC_RELAX_LONG_LOOP() in bench_stats_sym_finish() and bench_stats_asym_finish_ex();
wolfcrypt/test/test.c: fix rng_seed_test() with correct test vectors for the relevant combinations of features, and gate the test out if there are user override defines for ENTROPY_SCALE_FACTOR or SEED_BLOCK_SZ.
Defining WOLFSSL_WC_LMS_SERIALIZE_STATE will have the state serialized
before the private key data.
Lots of memory used but means fast reload times. That means that the key
can be reloaded for each sign.
-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.
defined, and issue a #error if no MPI backend gate is defined and NO_BIG_INT
is not defined either.
configure.ac:
* add support for FIPS lean-aesgcm[-{ready,dev}].
* implement handler for --enable-sha256.
* move setup for WOLFSSL_FIPS_DEV and WOLFSSL_FIPS_READY into the applicable
per-flavor sections.
* fix sensing of $ENABLED_AESGCM in FIPS setup clauses to pivot on `!= "no"`
rather than `= "yes"`, to accommodate "4bit" and other non-"yes" values.
* fix SNI_DEFAULT to be "no" if $ENABLED_TLS = no.
* fix ENABLED_DHDEFAULTPARAMS default to be $ENABLED_DH rather than yes.
wc_encrypt.c: add missing gates in wc_CryptKey() for NO_SHA256.
wolfcrypt/test/test.c: gating fixes for NO_SHA256.
wolfcrypt/benchmark/benchmark.c: basic fixes for building/running with
--disable-rng (-DWC_NO_RNG).
With the above additions and fixes, it's now a clean build, test, and benchmark,
with --disable-sha256 --enable-cryptonly --disable-hashdrbg --disable-rng
--disable-hmac, though RSA/DH/ECC benches are disabled.
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.
misc.c: when Intel x64 build, assume able to read/write unaligned
Matrix A is expensive to calculate.
Usage of ML-KEM/Kyber is
1. First peer generates a key and sends public to second peer.
2. Second peer encapsulates secret with public key and sends to first
peer.
3. First peer decapsulates (including encapsulating to ensure same as
seen) with key from key generation.
Caching A keeps the matrix A for encapsulation part of decapsulation.
The matrix needs to be transposed for encapsulation.
AES-GCM: don't generate M0 when using assembly unless falling back to C
and then use new assembly code.
HMAC: add option to copy hashes (--enable-hash-copy
-DWOLFSSL_HMAC_COPY_HASH) to improve performance when using the same key
for multiple operations.
