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.
* 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().
Thumb2/ARM32: use umaal instruction to speed up mulitplication, squaring
and reduction. umaal not always available so use umlal instead.
Implementations for architectures less than 4 still kept - no umull.
Cleanup point arithmetic to not take shortcuts.
Make masking for constant time faster.
Add alternate asm for different compilers.
Get ARMv4 and ARMv6 compiling.
Remove whitespace at end of lines.
SP ECC signing code was generating signatures with r of 0.
This is not allowed by the algorithm description.
Retry sig gen when r is 0 like when s is 0.
used and size have no reason to be negative - change type.
Change code to match unsigned change. Mostly change variables to be
unsigned where possible.
integer.c: Only have mp_rand_prime available when needed and
mp_prime_is_prime_ex is available.
Fixes from regression testing.
Fix for GeneratePublicDh was not right in #6002.
sp_DhExp_* are called from multiple functions.
Sometimes outLen contains a value and sometimes not.
Check public key output size in GeneratePublicDh before calling SP.
Enabling SP with ASM didn't enable SP or error out when SP wasn't
configured. Now enables SP when '' and errors when 'no'.
SAKKE modinv used large amounts of stack. Change to have more temporary
memory allocated increased to cover the usage.
ECC, SAKKE: sp_<bits>_ecc_mulmod_<cpu><words>() used large amounts of
stack. Allocate when WOLFSSL_SMALL_STACK.
wc_DhCheckKeyPair() not available when HAVE_SELFTEST.
Wasn't compiled in before as WOLFSSL_HAVE_SP_DH wasn't defined.
Specific compress key code for P521 doesn't need a n square function.
Fixing generation of x86_64 ASM scripts resulted in adding carriage
return to chacha_asm.S.
P-256/384/521.
New functions:
- sp_ecc_make_key_256_nb
- sp_ecc_make_key_384_nb
- sp_ecc_make_key_521_nb
- sp_ecc_secret_gen_256_nb
- sp_ecc_secret_gen_384_nb
- sp_ecc_secret_gen_521_nb
This commit also tweaks the testing for ECDSA testing in test.c. Instead of
testing with one of P-256/384/521, we test with all that are available.
Implement div words for different platforms.
Use implementation not using a divide instruction unless
SP_DIV_WORD_USE_DIV or we know there is a div instruction.
Fix Thumb implementation of div word.
GCM: make borrow constant time.
AES-GCM decrypt: compare at end and constant time.
Random: array_add touchs all elements every time.
RSA-OAEP: look for padding byte in constant time (look at every byte in
array).
SP
- reduce conditional use (make them bit ops)
- Fix point adds to not use double when adding infinity to infinity
- Implement signed div as __divi3 is not constant time.
- Move check sof input variables to API.
EC point add is a double if affine ordinates are the same.
Fix AVX2 implementation of mod inv to do conversion from 26 bits in
32-bit registers to 64 bits in 64-bit registers. Also handle negative
value.
RSA OAEP: loop down to last byte. Must have a separator.
Div for x86_64: fix to have all 1s when high word equals divisor.
Change Karatsuba implementations for x86_64.
Fix ECC code to better handle corner cases.
Add 'lower' versions of functions wehn an input is known to be less than m.
Add mont_add/dbl/tpl/sub for P384.
Change ECC point add to be cache-attack resistant.
Change mod_exp to be cache-attack resistant.
