Fixes to get WOLFSSL_PUBLIC_MP testing passing.
Fix DH constant time agreement:
- implement constant time encoding to big-endian byte array in TFM
- only force x to be zero for SP math as others implementations ensure
unused words are zero
- exponentiate in constant time to the smallest number of words
possible
- no need to encode into separate buffer anymore as encoding is
constant time and front padded
- make requested_sz be the maximum size for the parameters and check
against agreeSz
- update agreeSz to be the maximum valid size instead of filling all
the buffer which may be many times too big
- fix SP result to front pad when doing constant time
which force on BUILDING_WOLFSSL and do boilerplate includes, and update library
sources to include them at the top.
wolfssl_sources.h includes types.h, error-crypt.h, and logging.h, and
conditionally, config.h. settings.h and wc_port.h are unconditionally
included at the top of types.h.
wolfssl_sources_asm.h includes settings.h, and conditionally, config.h.
Add wolfssl_sources*.h to wolfcrypt/src/include.am, and to several IDE/ project
files.
Also added a TEST_WOLFSSL_SOURCES_INCLUSION_SEQUENCE clause in
wolfssl/wolfcrypt/settings.h to allow coverage testing.
In wolfcrypt/src/misc.c, retain existing ad hoc boilerplate includes, and use
them if WOLFSSL_VIS_FOR_TESTS, otherwise include the new wolfssl_sources.h.
Define WOLFSSL_VIS_FOR_TESTS at top of wolfcrypt/test/test.c.
Also renamed WOLFSSL_NEED_LINUX_CURRENT to WOLFSSL_LINUXKM_NEED_LINUX_CURRENT,
for clarity.
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)`.
wolfssl/wolfcrypt/error-crypt.h: add WC_FIRST_E.
wolfcrypt/src/error.c: add MP error code strings.
wolfssl/error-ssl.h: add WOLFSSL_FIRST_E and WOLFSSL_LAST_E.
wolfcrypt/test/test.c: update error_test() for new error code layout, refactoring the "missing" check.
src/internal.c: use WC_FIRST_E and WC_LAST_E in wolfSSL_ERR_reason_error_string().
src/ssl.c: fix wolfSSL_ERR_GET_REASON() to identify in-range error codes using WC_FIRST_E, WC_LAST_E, WOLFSSL_FIRST_E, and WOLFSSL_LAST_E.
sp_int.h: provide for WOLFSSL_DEBUG_TRACE_ERROR_CODES, and refactor MP error codes as enums, for consistency with other error codes.
wolfcrypt/src/ecc.c: fix 2 identicalInnerCondition's.
Add support for:
- SM2 elliptic curve and SM2 sign/verify
- SM3 digest
- SM4 cipher with modes ECB/CBC/CTR/GCM/CCM
Add APIs for SM3 and SM4.
Add SM2 sign and verify APIs.
Add support for SM3 in wc_Hash and wc_Hmac API.
Add support for SM3 and SM4 through EVP layer.
Add support for SM2-SM3 certificates. Support key ID and name hash being
with SHA-1/256 or SM3.
Add support for TLS 1.3 cipher suites: TLS-SM4-GCM-SM3, TLS-SM4-CCM-SM3
Add support for TLS 1.2 SM cipher suite: ECDHE-ECDSA-SM4-CBC-SM3
Add support for SM3 in wc_PRF_TLS.
Add SM2-SM3 certificates and keys. Generated with GmSSL-3.0.0 and
OpenSSL.
The modular exponentiation implementations in sp_int.c and tfm.c are not
safe when using Encrypted Memory.
Cannot have two pieces of memory where one changes and the other doesn't
based on private value.
Use extra variable to hold the two new values and assign them both back
at the same time in a safe manner.
Alternative implementations used when WC_PROTECT_ENCRYPTED_MEM is
defined.
src/internal.c: fix for -Wdeclaration-after-statement and clang-diagnostic-unreachable-code-break;
tests/api.c: fix for -Wunused-variable and clang-analyzer-deadcode.DeadStores;
olfcrypt/src/pkcs12.c: fixes for cppcheck uselessAssignmentPtrArg and arrayIndexThenCheck, and clang-tidy clang-analyzer-deadcode.DeadStores and clang-analyzer-core.NonNullParamChecker;
wolfssl/src/tls.c: fix for clang-analyzer-deadcode.DeadStores;
wolfcrypt/src/tfm.c: fix for clang-diagnostic-newline-eof;
src/tls13.c: fix for clang-analyzer-core.NonNullParamChecker.
BN APIs from ssl.c have been moved out to ssl_bn.c that is included in
ssl.c.
Added defines for BN_rand() and BN_pseudo_rand() to indicate which bits
are to be set.
'internal' field now always maps to the ;mpi' field that is a MP
integer.
SetIndividualInternal/External renamed to wolfssl_bn_get/set_value.
Fixed BN APIs to work as closely to OpenSSL as possible.
Added tests.
Moved wolfssl_make_rng out to ssl.c as BN APIs are using it now.
SP int and TFM now check trials are in a valid range for
mp_prime_is_prime_ex().
mp_to_unsigned_len checks length and front pads with zeros.
Return MP_VAL when length is too small in all implemenations.
Make TFM implementation check length.
Add test case.
* fix compilation warning
* adjust SHA3-384 test error-codes
The way the codes were constructed before, they were not unique.
* unify code
Instead of having `ifdef`'s in the code, define our own wrapper around
the keysource as required.
* add CMake option for help-text in wolfCrypt tests
* expose test `main()` as `wolfcrypt_test_main()`
* Don't overwrite previously set errors
* add FreeRTOS support for Xilinx demo
* move `fp_reverse` from `tfm.c` to `wolfmath.c` and rename to
`mp_reverse`.
