* 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.
* tls: negotiate until hs is complete in wolfSSL_read/wolfSSL_write
Don't rely on ssl->options.handShakeSate == HANDSHAKE_DONE to check if
negotiation is needed. wolfSSL_Connect() or wolfSSL_Accept() job may not yet be
completed and/or some messages may be waiting in the buffer because of
non-blocking I/O.
* tests: test case for handshake with wolfSSL_read()/wolfSSL_write()
* doc: clarify wolfSSL_write()
* internal.c: rename: need_negotiate -> ssl_in_handshake
- dtls: check that the cookie secret is not emtpy
- Dtls13DoDowngrade -> Dtls13ClientDoDowngrade
- dtls: generate both 1.2 and 1.3 cookie secrets in case we downgrade
- dtls: setup sequence numbers for downgrade
- add dtls downgrade sequence number check test
Fixes ZD17314
Multiple handshake messages in one record will fail the MsgCheckBoundary() check on the client side when the client is set to TLS 1.3 but allows downgrading.
--> ClientHello
<-- ServerHello + rest of TLS 1.2 flight
Client returns OUT_OF_ORDER_E because in TLS 1.3 the ServerHello has to be the last message in a record. In TLS 1.2 the ServerHello can be in the same record as the rest of the server's first flight.
