Relax the dependencies of the tests about handshake
message defragmentation/reassembly on server side.
TLS 1.3 does not need to be enable anymore for this
to work for TLS 1.2 handshake messages.

The original macro was accounting for the size of public FFDH keys,
which are not a concern for PK. Use sizes for key types supported by PK,
this brings the size of the buffer from 1kB to 528 bytes in the default
config.

In all.sh component test_psa_crypto_config_accel_rsa_crypto, where RSA
is provided only by a drivers, we were using a stack buffer. However
that was not correct, as "opaque" (PSA-held) RSA keys are still
possible. This was pointed by failing test cases in test_suite_pk, such
as "PSA import into PSA: opaque RSA, EXPORT (ok)".
As usual with 3.6, we need more complicated pre-processor conditions.

The type was validated near the end of the function when importing, but
if makes more sense to validate upfront before we possibly allocate a
buffer, export the key to it etc.
This also guarantees a sensible error value without requiring a special
case when exporting on the stack.

This makes test_suite_pk pass again, but beyond that I think it's the

This is not only convenient, but now necessary, because if the content of
the generated files changes due to changes in Python files in the framework,
`all.sh check_generated_files` will fail in the framework CI.

We are about to have full support for TLS 1.2
CH reassembly on server side. The equivalent
positive test would be a duplicate of one of
the tests generated by generate_tls_handshake_tests.py.
Thus just removing the negative test.

When we are using PSK or authmode is MBEDTLS_SSL_VERIFY_NONE, set
verify_result to 0 rather than MBEDTLS_X509_BADCERT_SKIP_VERIFY.
This is specific to the 3.6 LTS, to preserve the previous behaviour of
the library in these cases, which was determined by the default value
of verify_result being 0.

We do not return failure, but return -1u which is documented as a value
that indicates that the result is not available.

When we are using PSK or when authmode == MBEDTLS_SSL_VERIFY_NONE, we
intentionally do not verify the certificate. In these cases, do not keep
verify_result at -1u but set it to MBEDTLS_X509_BADCERT_SKIP_VERIFY to
indicate that no certificate verification took place.

Initialize the verify_result field in mbedtls_ssl_session_free().
Previously we were just zeroising the entire session object, which would
yield a default 'success' value if the same object were reused.
Test that this initialisation is actually happening by setting
verify_result manually to zero and calling mbedtls_ssl_session_free() on
the session before checking its value.

Since we explicitly document the value 0xFFFFFFFF or -1u as representing
'result not available', we can use it as a sensible default value
without creating an API change. Use this value instead of introducing a
new verification result value.

Write a testcase to get verify_result before we have performed a
handshake and make sure that it is initialised to a failure value.
Signed-off-by: David Horstmann <david.horstmann@arm.com>
At initialization, set the verify_result field of the ssl session to
MBEDTLS_X509_VERIFY_NOT_STARTED, rather than 0 as it is by default
currently. This prevents mbedtls_ssl_get_verify_result() from indicating
that certificate verification has passed if it is called prior to the
handshake happening.

Add a new verification result bitflag MBEDTLS_X509_VERIFY_NOT_STARTED
to use as a safe initial value for verify_result. This is better than
the current initial value which is 0 (indicating success).

In the TLS-Exporter for TLS 1.3 we mistakenly call PSA_HASH_LENGTH() on
an mbedtls_md_type_t when it should be called on a psa_algorithm_t.
Fortunately, these two types have almost the same values, since we have
previously aligned them to make conversion more efficient. As a result,
PSA_HASH_LENGTH() produces exactly the same value when called on an
mbedtls_md_type_t as with the equivalent psa_algorithm_t.
Thanks to this happy coincidence, fix a largely cosmetic issue (rather
than a major functional bug).
