Anthony Hu 00d0b09401 Fix buffer-overflow in LMS leaf cache indexing
wc_lms_treehash_init() writes leaf node hashes into the leaf cache
using an absolute index (i * hash_len), but the cache is only
max_cb entries starting from leaf->idx. When leaf->idx > 0 (which
occurs when wc_LmsKey_Reload is called after signing more than
max_cb times), the write goes past the end of the cache buffer.

Fix by using the relative offset (i - leaf->idx) * hash_len instead.

Added unit tests (test_lms.c):
  - test_wc_LmsKey_sign_verify: basic sign/verify sanity check
  - test_wc_LmsKey_reload_cache: (TDD) reproduces the overflow by
    signing 33 times then reloading the key

Tobias Frauenschläger 14ce7956f1 Increase test coverage
* More PQC configurations
* More CMake setups
* Fix various bugs uncovered by these tests

Added some missing feature additions to CMake to make the example
`user_settings_all.` config file work for the CI test.

Sean Parkinson da0e4f59ec LMS - check sum fix for SHA-256-192
Only 8 bits needed of checksum whem doing 192-bit hashes with Winternitz
of 1 (9 for 256-bit hashes).
Cleanup code around checksum.

Sean Parkinson 36c953dd8f LMS: Cast constants before shifting left
Compiling for 16-bit results in some constants type being too small for
shift amount without cast.

Sean Parkinson d05790ed89 LMS: Allow state to be saved with private key
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.

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.

Daniel Pouzzner 7cd2fd3617 numerous fixes for memory errors reported by clang-tidy, most of them true positives, unmasked by CPPFLAGS=-DNO_WOLFSSL_MEMORY: clang-analyzer-unix.Malloc, clang-analyzer-core.NullDereference, clang-analyzer-core.uninitialized.Assign, clang-analyzer-core.UndefinedBinaryOperatorResult, and clang-analyzer-optin.portability.UnixAPI (re malloc(0)).
several fixes for defects reported by cppcheck:

wolfcrypt/src/ecc.c: fix for cppcheck oppositeInnerCondition from cppcheck-2.16.0 in _ecc_make_key_ex(), and fixes for related unhandled errors discovered by manual inspection;

wolfcrypt/test/test.c: fix XREALLOC call in memcb_test() to resolve cppcheck-detected memleak.

src/ssl_crypto.c, wolfcrypt/src/wc_lms.c, wolfcrypt/src/wc_lms_impl.c, wolfcrypt/src/wc_xmss.c, wolfcrypt/test/test.c: add missing casts for XMALLOC()s.
