In some cases the values were negative.

Changed 128-bit variable implementation of Curve25519. (generated)
Changed Ed25519 C implementation.

Daniel Pouzzner c401f5caf2 move the newly added wolfcrypt/src/wolfssl_sources.h to wolfssl/wolfcrypt/libwolfssl_sources.h, and likewise for wolfssl_sources_asm.h; revert changes to IDE/ project files. 2025-04-04 18:44:12 -05:00
Daniel Pouzzner 217440c885 Add wolfcrypt/src/wolfssl_sources.h and wolfcrypt/src/wolfssl_sources_asm.h,
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.

Sean Parkinson f8bc819fb5 ASM, SP, C regeneration
Fix spaces at start of copyright line in .asm files.
Changed generation of X25519 and Ed448 code to better match changes
already in C code. Fixed formatting in places.

Daniel Pouzzner b2f594e84b fixes for --enable-32bit CFLAGS=-m32 --enable-fips=v6 (fixes "#error ED448 requires SHAKE256"). 2024-04-17 00:43:41 -05:00
Daniel Pouzzner 44e0ee1ecd wolfssl/wolfcrypt/types.h:
* fix overallocation in WC_DECLARE_ARRAY() macro in the !WOLFSSL_SMALL_STACK path.
* rename WC_INIT_ARRAY() to WC_ALLOC_ARRAY() for clarity (it doesn't initialize any memory).
* rename WC_DECLARE_ARRAY_DYNAMIC_DEC(), WC_DECLARE_ARRAY_DYNAMIC_EXE(), and WC_FREE_ARRAY_DYNAMIC() to WC_DECLARE_HEAP_ARRAY(), WC_ALLOC_HEAP_ARRAY(), and WC_FREE_HEAP_ARRAY(), respectively, also for clarity, and refactor out the duplicate definitions.
* add WC_ALLOC_VAR(), and move the XMALLOC() in smallstack WC_DECLARE_VAR() into it.  smallstack WC_DECLARE_VAR() now initializes the pointer to NULL, like smallstack WC_DECLARE_ARRAY(), assuring all pointers are valid upon shortcircuit to cleanup for a failed allocation (see WC_ALLOC_DO_ON_FAILURE below).
* add a new hook "WC_ALLOC_DO_ON_FAILURE" in WC_ALLOC_VAR(), WC_ALLOC_ARRAY(), and WC_DECLARE_ARRAY_DYNAMIC_EXE(), which is invoked when an allocation fails.  by default the hook is defined to WC_DO_NOTHING.
* add basic safety to WC_*_HEAP_ARRAY() by recording/detecting allocation state via idx##VAR_NAME.
* add macros WC_ARRAY_OK() and WC_HEAP_ARRAY_OK() to test if allocation succeeded.
* add macros WC_CALLOC_ARRAY() and WC_CALLOC_HEAP_ARRAY() which zero the objects.
* add macro WC_CALLOC_VAR() which zeros the object.

ED448: smallstack refactor of ge448_scalarmult_base().

src/tls.c tests/api.c wolfcrypt/test/test.c: update WC_DECLARE_VAR()s with now-required matching WC_ALLOC_VAR()s.

wolfcrypt/benchmark/benchmark.c:
* no functional changes in default error-free behavior.
* add definition of WC_ALLOC_DO_ON_FAILURE() that prints error message, sets ret, and does goto exit.
* add BENCH_NTIMES and BENCH_AGREETIMES overrideeable macros, to allow fast sanitizer runs and slow high-precision runs.
* smallstack refactor of all declarations of stack arrays of the form foo[BENCH_MAX_PENDING], using WC_DECLARE_ARRAY() (35 in all).
* additional smallstack refactors, using WC_DECLARE_VAR(), for bench_aesxts(), bench_ed448KeyGen(), bench_eccsi*(), and bench_sakke*().
* fixes for various unhandled error conditions around malloc failures.

wolfcrypt/test/test.c: opportunistically constify several (42) static constants, moving them to the readonly data segment.

linuxkm/Makefile: if ENABLED_LINUXKM_BENCHMARKS, add wolfcrypt/benchmark/benchmark.o to WOLFSSL_OBJ_FILES.

linuxkm/Kbuild: enable FPU for benchmark.o, and remove enablement for module_hooks.o.

linuxkm/module_hooks.c: remove inline include of benchmark.c.

Sean Parkinson a242424abe Generated files: fixes
Fixups from updating scripts that generate the files.
Include settings.h for ARM32 assembly.
ARM32 SHA-512 ASM has only one function, Transform_Sha512_Len(). The
implementation is dependent on defines.
