Daniel Pouzzner 70aa3dc5b1 20260204-linuxkm-fips-hash: more fixes+improvements from peer and AI review:
linuxkm/linuxkm_memory.c:

linuxkm/linuxkm_memory.h: fix initializer for wc_reloc_table_segments.bss_end;

wolfssl/wolfcrypt/settings.h: add WC_BITS_TO_BYTES() and WC_BITS_FULL_BYTES() and deploy opportunistically to wolfssl/internal.h, wolfssl/wolfcrypt/{asn.h,dh.h,rsa.h,types.h}, wolfcrypt/src/sakke.c, and wolfcrypt/test/test.c.

JacobBarthelmeh a156ed7bc7 update Copyright year 2026-02-18 09:52:21 -07:00
Daniel Pouzzner 7ea66aeffe refactor WOLFSSL_LINUXKM gates as generic WOLFSSL_KERNEL_MODE gates where appropriate:
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.

Daniel Pouzzner 77dccc0c32 linuxkm:
* 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.

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.

David Garske 99daac3974 Improvement for SAVE_VECTOR_REGISTERS 2024-11-01 13:57:02 -07:00
Daniel Pouzzner c81c9be9ce error code fixes:
* 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().

JacobBarthelmeh 31a6a2bf59 update copyright to 2024 2024-07-19 13:15:05 -06:00
Daniel Pouzzner 1b907d05ed WOLFSSL_DEBUG_TRACE_ERROR_CODES: restore several initializations, one because needed (in wolfSSL_UseSecureRenegotiation()), the rest in an abundance of caution, and rearrange wolfSSL_CryptHwMutexInit() and wolfSSL_CryptHwMutexUnLock() in a similar abundance of caution. 2024-06-10 13:44:03 -05:00
Daniel Pouzzner b3e8f0ad24 add --enable-debug-trace-errcodes, WOLFSSL_DEBUG_TRACE_ERROR_CODES, WC_ERR_TRACE(), WC_NO_ERR_TRACE(), support/gen-debug-trace-error-codes.sh. also add numerous deployments of WC_NO_ERR_TRACE() to inhibit frivolous/misleading errcode traces when -DWOLFSSL_DEBUG_TRACE_ERROR_CODES. 2024-06-08 16:39:53 -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.
2024-02-16 10:26:21 -06:00
Daniel Pouzzner 6146485d2a linuxkm/linuxkm_wc_port.h:
* 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.

Daniel Pouzzner f771181e1a fixes for issues introduced in #5384:
added numerous missing _SMALL_STACK code paths (PK objects on the stack);

in settings.h, enable WOLFSSL_SMALL_STACK_STATIC by default when WOLFSSL_SMALL_STACK is defined (NO_WOLFSSL_SMALL_STACK_STATIC to override);

fixes for unsafe strcat()s in tests/quic.c;

fix for unsafe macro WOLFSSL_IS_QUIC();

fix to exclude quic from enable-all when enable-linuxkm (quic needs opensslextra, and opensslextra currently only works in-kernel in cryptonly builds);

fix for signed/unsigned clash in wolfSSL_quic_receive().
