Ensure dsa->g is initialized with other mp_ints so that it can be
cleared at the end regardless of failures.
Don't clear tmp or tmp2 if allocation or initialization failed as you
will access uninitialized data.
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_linuxkm_check_for_intr_signals(), wc_linuxkm_relax_long_loop(),
WC_CHECK_FOR_INTR_SIGNALS(), WC_RELAX_LONG_LOOP(), SAVE_NO_VECTOR_REGISTERS(),
RESTORE_NO_VECTOR_REGISTERS(), and new error code INTERRUPTED_E ("Process
interrupted");
* update the no-asm remaps in the PK implementations to use
SAVE_NO_VECTOR_REGISTERS() and RESTORE_NO_VECTOR_REGISTERS(), so that inner
loops in them are always covered by the new logic.
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().
* add support for DEBUG_LINUXKM_FORTIFY_OVERLAY to allow KASAN analysis of the overlay without actually enabling CONFIG_FORTIFY_SOURCE (which is buggy in combination with KASAN).
* make SAVE_VECTOR_REGISTERS2 definition conditional on !defined(SAVE_VECTOR_REGISTERS2).
wolfssl/wolfcrypt/memory.h: fix the DEBUG_VECTOR_REGISTER_ACCESS definition for SAVE_VECTOR_REGISTERS to properly omit the on-success bookkeeping code even if the supplied fail_clause doesn't return.
wolfcrypt/src/rsa.c: in wc_MakeRsaKey() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/dh.c: in wc_DhGenerateParams() primality loop, invoke RESTORE_VECTOR_REGISTERS() SAVE_VECTOR_REGISTERS() to prevent lengthy kernel lockups.
wolfcrypt/src/{curve25519.c,dh.c,dsa.c,ecc.c,eccsi.c,rsa.c,sakke.c,sp_int.c}: when WOLFSSL_LINUXKM, force {SAVE,RESTORE}_VECTOR_REGISTERS() to WC_DO_NOTHING if settings gate out applicable asm.
* Add introspection for math build.
* Raise build error if more than one multi-precision math library used.
* Fix ESP32 to support using any multi-precision math option.
* Refactor math headers to use `wolfmath.h`
* Refactor of the opaque math variable type `MATH_INT_T` used by crypto hardware (QuickAssist, SE050, ESP32 and STM32).
* Cleanups for building with `WOLFCRYPT_ONLY` and `NO_BIG_INT`.
* Stop forcing use of fast math by default for platforms in settings.h. Note: For users that still want to use fast math (tfm.c) they will need to add USE_FAST_MATH to their build settings.

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.
If NULL is passed as the digest argument of wc_DsaSign(), mp_clear() will be
called before mp_init() is called. This can cause segmentation fault.

test_wc_DsaSignVerify() passes the tests but causes an error.
free(): invalid pointer
If NULL is passed as the digest argument of wc_DsaVerify(), mp_clear() will be
called before mp_init() is called. On qemu-i386, the dp field of the mp_int
structure is non-null by default, which causes a segmentation fault when calling
mp_clear(). However, if WOLFSSL_SMALL_STACK is enabled, this problem does not
occur.
