wolfssl/internal.h: add DTLS13_HANDSHAKE_HEADER_SZ;
src/tls13.c: in EchHashHelloInner(), use falseHeader[DTLS13_HANDSHAKE_HEADER_SZ] to fix buffer overrun;
src/dtls13.c: add static assert for DTLS13_HANDSHAKE_HEADER_SZ.
* 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().
tests/api.c: add error_test() adapted from wolfcrypt/test/test.c, checking all error strings for expected presence/absence and length, called from existing test_wolfSSL_ERR_strings().
wolfssl/ssl.h, wolfssl/error-ssl.h, and wolfssl/wolfcrypt/error-crypt.h:
* move several negative error return codes from ssl.h to error-ssl.h,
* renumber them to conform to existing sequence, and
* include error-ssl.h from ssl.h;
* add special-case WOLFSSL_DEBUG_TRACE_ERROR_CODES macros for WOLFSSL_FAILURE;
* add missing WOLFSSL_API attribute to wc_backtrace_render().
add numerous WC_NO_ERR_TRACE()s to operand error code uses, cleaning up error traces in general, and particularly when WOLFSSL_DEBUG_TRACE_ERROR_CODES_ALWAYS.
* crypto lib (36),
* crypto test&benchmark (20),
* TLS lib (179),
* examples (122),
* linuxkm (3),
* tests/api.c (2272).
- DTLS 1.3 pqc support
- Add --enable-dtls-frag-ch option to enable CH fragmenting
- Send an alert when we get an empty keyshare with a cookie present to not allow for multiple HRR in one connection
- Only update the DTLS window when we have successfully processed or stored a message
- Call ssl->chGoodCb as soon as we have processed a verified full or fragmented ClientHello cookie
dtls13.c:
Change end of outputBuffer data calculations to use function
GetOutputBuffer().
Use idx when calculating unused byte count of outputBuffer.
internal.c:
Change end of outputBuffer data calculations to use function
GetOutputBuffer().
Use GetOutputBuffer() to calculate end of data in outputBuffer.
GrowOutputBuffer():
Calculate new size to allocate to include already written data in
case of static buffer.
Copy all data including already written count (idx).
CheckAvailableSize():
Don't subtract idx from length when checking MTU size.
Do subtract idx from bufferSize to determine count of unused bytes
in outputBuffer.
