Added a new version of 'nofail' handshaking that doesn't use threads.
More tests can be run in single threaded.
Changed tests over to use test_wolfSSL_client_server_nofail() or
test_wolfSSL_client_server_nofail_memio() to simplfy test cases.
Changed tests to use Expect.
CRL:
BufferLoadCRL wasn't freeing allocated data when currentEntry
couldn't be allocated.
ssl.c:
DecodeToX509(): Needs to call FreeDecodedCert even if
ParseCertRelative fails.
wolfSSL_PEM_read_PUBKEY(): Need to check result of
wolfSSL_d2i_PUBKEY is NULL rather than the passed in WOLFSSL_EVP_PKEY.
X509:
wolfSSL_X509_set_ext(): Must free allocated WOLFSSL_X509_EXTENSION
if not pushed on to stack regardless of stack being NULL.
wolfSSL_X509V3_EXT_i2d(): Don't free asn1str on error as it is the
data passed in.
wolfSSL_i2d_X509_NAME_canon(): free names and cano_data when call to
wolfSSL_ASN1_STRING_canon() fails.
PKCS7:
wc_PKCS7_InitWithCert(): Check memory allocation of cert for NULL.
Modified number of tests to not crash on failure and cleanup allocations
on failure.
Added memory fail count option to set which memory allocation to start
failing on.
Fix issues found from testing.
bio.c:
BIO_new() move ref count up so that calls to wolfSSL_BIO_free()
work.
internal.c:
ImportCipherSpecState wasn't checking SetKeySide for failure. Crash
when pointer is NULL and accessed directly.
ocsp.c:
wolfSSL_OCSP_response_get1_basic() doesn't need to free vs->source
as it is freed in WOLFSSL_OCSP_RESPONSE_free().
ssl.c:
ProcessBuffer() Don't strip PKCS#8 header if failed to create DER.
Crasged as directly accessing 'der' which was NULL.
ssl_asn.c:
wolfssl_asn1_integer_require_len was checking wrong variable to see
if allocation failed.
x509,c:
wolfSSL_X509_ALGOR_set0 needs to set aobj only when no failure
possible.
wolfSSL_X509_chain_up_ref needs to call cleanup to ensure everything
is freed.
wolfSSL_X509_NAME_ENTRY_get_object
- object field was being reused if it existed but lost on error
- store object only on success, ie object is not NULL
- moved function into x509.c
wolfSSL_X509_NAME_ENTRY_create_by_txt and
wolfSSL_X509_NAME_ENTRY_create_by_NID:
- object field was being reused if it existed but lost on error
- extracted common code
- store object only on success, ie object is not NULL
In DTLS v1.3 the normal (plaintext) record header can be used only with
unprotected message (epoch == 0). Protected messages use the unified header.
Check this invariant using `IsAtLeastTLSv1_3` instead of `ssl->options.tls1_3`
because the latter is false before version negotiation.
In DTLSv1.2 the DTLS normal header is used for all the epoch, this check doesn't
interfere because:
1. the first CH's epoch must be zero in all DTLS versions
2. In case of downgrade after version negotiation `IsAtLeastTLSv1_3` is false
