Daniel Pouzzner 06d3d6d3df linuxkm/Kbuild and linuxkm/module_hooks.c: refactor wc_linuxkm_pie_reloc_tab to include ground truth segment tag from ELF metadata.
tweaks for ARM32: recognize R_ARM_* relocations, and add -fno-unwind-tables to PIE_FLAGS.

linuxkm/linuxkm_wc_port.h:
* __PIE__: don't declare static pmd_to_page() unless USE_SPLIT_PMD_PTLOCKS.
* add wc_lkm_refcount_to_int() helper with -Wnested-externs suppressed.

wolfcrypt/src/fe_operations.c: in fe_frombytes() and fe_sq2(), use explicit XMEMSET()s to initialize working vars, rather than implicit, to avoid implicit (unshimmable) memset() calls.

wolfcrypt/src/ge_operations.c: fix gate on _wc_curve25519_dummy() to require CURVED25519_ASM.

Sean Parkinson 574067e204 Curve25519: lshift of a negative value is undefined in C
Change all left shifts to be of unsigned values.
In some cases the values were negative.

Added macros to make the code easier to be consistent.

Daniel Pouzzner d15523a6df fix gating in wolfssl/wolfcrypt/fe_operations.h -- gate out load_3() and load_4() when !(CURVE25519_SMALL || ED25519_SMALL);
harmonize low-mem outer gate in wolfcrypt/src/fe_operations.c with outer gate in wolfcrypt/src/fe_low_mem.c.

wolfcrypt/src/curve25519.c: if defined(NO_CURVED25519_X64), #undef USE_INTEL_SPEEDUP;

wolfcrypt/src/fe_operations.c: fixes for -m32 -Wconversions;

.github/workflows/wolfCrypt-Wconversion.yml: add -m32 scenario;

.wolfssl_known_macro_extras: remove unneeded entry for WOLFSSL_CURVE25519_BLINDING.

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 932513a41e fixes for various -W*conversions in sp_int.c, asn.c, fe_operations.c, fe_448.c, ge_448.c. also, add support for NO_INT128, and add .github/workflows/wolfCrypt-Wconversion.yml. 2025-03-06 16:08:38 -06:00
Sean Parkinson bb84ebfd7a Curve25519: add blinding when using private key
XOR in random value to scalar and perform special scalar multiplication.
Multiply x3 and z3 by random value to randomize co-ordinates.

Add new APIs to support passing in an RNG.
Old APIs create a new RNG.

Only needed for the C implementations that are not small.

Modified TLS and OpenSSL compat API implementations to pass in RNG.

Fixed tests and benchmark program to pass in RNG.

Ralf Schlatterbeck 63c6c47165 Fixes for 16-bit systems
Systems with sizof(int) == 2 default to expressions with that size.
So we have to do some explicit casts or use unigned long constants in
some cases.
In ssl.h the prototype of a function was not matching the definition.
This resulted in a type incompatibility on a 16-bit system.
