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.
Check that the Ed25519 and Ed448 public key is valid even without
private key.
Perform pairwise consistency test, only in FIPS, when making a key i
Ed25519 and Ed448.
* 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.
Ed25519 and Ed448 make public key APIs now check whether the private key
was set.
The private key and public key flags setting and clearing also updated.
Testing of unset private key and calling make public key added for
Ed25519 and Ed448.
In defense against attack, assume the imported public key is not trusted
and check it matches the private key if set.
Added APIs that allow application to explicitly trust public key.
Original APIs default to not trusting public key.
Add a define WOLFSSL_CHECK_MEM_ZERO to turn on code that checks that
memory that must be zeroized before going out of use is zero.
Everytime sensitive data is put into a allocated buffer or stack buffer;
the address, its length and a name is stored to be checked later.
Where the stack buffer is about to go out of use, a call is added to
check that the required parts are zero.
wc_MemZero_Add() adds an address with length and name to a table of
addressed to be checked later.
wc_MemZero_Check() checks that the memory associated with the address is
zeroized where required.
mp_memzero_add() adds mp_int's data pointer with length and name to
table.
mp_memzero_check() checks that the data pointer is zeroized where
required.
Freeing memory will check the address. The length was prepended on
allocation.
Realloction was changed for WOLFSSL_CHECK_MEM_ZERO to perform an
allocate, check, copy, free.
Allow Chachac20-Poly1305 to take an empty msg.
Allow AES-SIV to have an empty nonce.
Don't allow the length to be malleable. Must use the smallest number of
bytes to represent value.
ECDSA and DSA signature values are positive.
Add Sha512-224 and Sha512-256 OIDs.
ASN template - ensure the ECDSA/DSA signature uses all data.
Curve25519/Curve448 - WOLFSSL_ECDHX_SHARED_NOT_ZERO means shared secret
can't be 0.
Curve25519/Curve448 - check public value is less than order.
ECC - x or y may be zero but not both.
Ed25519/Ed448 - check S is less than order.
Ed448 - ge_p3_dbl can be simplified for ASM.
Prime check (integer.c/tfm.c/sp_int.c): Don't allow negative values and
make sure random candidate doesn't have bits higher than those in a set
when bits not a multiple of 8.
RSA: support Sha512-224 and Sha512-256.
RSA: Fix check for invalid in decryption. Affects plaintexts 256 bytes
and longer.
RSA: Don't allow base be larger than modulus.
RSA: Check small ciphertext (1 or 0) on decrypt when not using OAEP.
RSA: WOLFSSL_RSA_DECRYPT_TO_0_LEN allows decrypted value to be 0.
SP math all: fix div to handle large a and d when checking size of
remainder.
SP math all: set sign of result in sp_mod_2d()
refactor ED routines to pivot on WOLFSSL_ED*_PERSISTENT_SHA and WOLFSSL_ED*_STREAMING_VERIFY macros, with sha state in the key struct only when WOLFSSL_ED*_PERSISTENT_SHA, otherwise on the stack as before;
add ed*_hash_init() and ed*_hash_free() local helpers;
ED* peer review: fix line lengths, remove superfluous retval checks, tweaks for efficiency, and add ED448_PREHASH_SIZE to ed448.h.
harmonize the ED448 API with the ED25519 API by making wc_ed448_verify_msg_ex() and wc_ed448_init_ex() public functions;
track devId and heap pointer in ed*_key.{devId,heap}, and pass them through to sha init functions;
add ed*_key.{sha,sha_clean_flag}, and ed*_hash_{reset,update,final} functions, and use them for all ED hashing ops, to support streaming API and for optimally efficient reuse for the preexisting ED calls;
add ed448_hash() akin to ed25519_hash(), and use it in place of wc_Shake256Hash(), for .sha_clean_flag dynamics.
add to wc_ed*_import_private_key() the ability to import the combined key generated by wc_ed*_export_private() without supplying the redundant public key;
add macro asserts near top of ed*.h to assure the required hash functions are available;
fix {NO,HAVE}_ED*_{SIGN,VERIFY};
wolfcrypt/test/test.c: add missing key initializations in ed*_test();
wolfcrypt/test/test.c: fix unaligned access in myDecryptionFunc() detected by -fsanitize=address,undefined.
