1f186ff330 Add missing calls to USE_PSA_DONE

left where using the new macros would be better).

9634bb10d9 Move helper testing functions to tests/src/helpers.c
Moves the functions `test_fail`, `test_set_step`, `test_skip` and the struct
`test_info` from `tests/suites/helpers.function` to `tests/src/helpers.*`.
This is done to open these functions up to the API where they can be used by
other functions in the 'src' test infrastructure module.

As the functions are now contained within the src folder of the testing
infrastructure, the `mbedtls_` prefix has been added to the functions.

70d7fb0c2d Don't hardcode TLS 1.3 labels in test cases
ssl_tls1_3_keys.c exports a structure containing all labels used
in the TLS 1.3 key schedule, but the TLS 1.3 key scheduling unit
tests so far replicated those labels in the test file. In particular,
wrong label values in ssl_tls1_3_keys.c wouldn't have been caught
by the unit tests.

This commit modifies the TLS 1.3 key schedule unit tests to use
the TLS 1.3 labels as exported by ssl_tls1_3_keys.c. This not only
makes sure that those labels are correct, but also avoids hardcoding
their hex-encoding in the test file.

7fe2c5f086 Add mbedtls_ssl_cf_memcpy_offset() with tests
The tests are supposed to be failing now (in all.sh component
test_memsan_constant_flow), but they don't as apparently MemSan doesn't
complain when the src argument of memcpy() is uninitialized, see
https://github.com/google/sanitizers/issues/1296

The next commit will add an option to test constant flow with valgrind, which
will hopefully correctly flag the current non-constant-flow implementation.

65a6fa3e26 Make cf_hmac() STATIC_TESTABLE
The test function now depends on MBEDTLS_TEST_HOOKS, which is enabled by
config.py full, and since there are already components in all.sh exercising
the full config, this test function is sill exercised even with this new
dependency.

Since this is the first time a test function depends on MBEDTLS_TEST_HOOKS,
fix a bug in check-names.sh that wasn't apparent so far: headers from
library/*.h were not considered when looking for macro definitions. This
became apparent because MBEDTLS_STATIC_TESTABLE is defined in library/common.h
and started being used in library/ssl_msg.c, so was flagged as a likely typo.

045f094c81 Add dummy constant-flow HMAC function with tests
The dummy implementation is not constant-flow at all for now, it's just
here as a starting point and a support for developing the tests and putting
the infrastructure in place.

Depending on the implementation strategy, there might be various corner cases
depending on where the lengths fall relative to block boundaries. So it seems
safer to just test all possible lengths in a given range than to use only a
few randomly-chosen values.

Compared to the previous approach of having the bad padding provided as input

with less test cases in the .data file and more important no manually-generated
non-trivial data in the test case parameters, making it much easier to
complete the testing matrix.

b2713abb8f Enhance record encryption unit tests by checking hidden content type
TLS 1.3 and DTLS 1.2 + CID hide the real content type of a record
within the record's inner plaintext, while always using the same
content type for the protected record:
- TLS 1.3 always uses ApplicationData
- DTLS 1.2 + CID always uses a special CID content type.

This commit enhances the record encryption unit test to check
that the record content type is indeed correctly hidden.

Improve pointer calculations when resizing I/O buffers
This commit introduces two changes:
- Add in_msg and out_msg calculations for buffer upsizing. This was previously
considered as unnecessary, but renegotiation using certain ciphersuites needs
this.
- Improving the way out_msg and in_msg pointers are calculated, so that even 
if no resizing is introduced, the pointers remain the same;

New tests added:
- various renegotiation schemes with a range of MFL's and ciphersuites;
- an ssl-opt.sh test exercising two things that were problematic: renegotiation
with TLS-ECDHE-ECDSA-WITH-AES-128-CCM-8 and a server MFL that's smaller
than the one negotiated by the client.

1a44a159ef Change the order of endpoint initialization steps
Wrong order caused the `protected_record_size` to be of wrong size, hence
causing the server to receive a malformed message in case of a DTLS test.

the buffers are empty and full.

b29807413e Refactor certificates and keys in ssl handshake mock tests
Let the caller decide what certificates and keys are loaded (EC/RSA)
instead of loading both for the server, and an unspecified one 
for the client. Use only DER encoding.

d796e19d3b Fix memory allocation fail in TCP mock socket
Because two buffers were aliased too early in the code, it was possible that
after an allocation failure, free() would be called twice for the same pointer.

890b5ca330 Change non-blocking read/write in TCP mock socket
Previously mocked non-blocking read/write was returning 0 when buffer was empty/full. That was causing ERR_SSL_CONN_EOF error in tests which was using these mocked callbacks. Beside that non-blocking read/write was returning ERR_SSL_WANT_READ/_WRITE depending on block pattern set by test design. Such behavior forced to redesign of these functions so that they could be used in other tests

fb437d72ef Fix segmentation fault in mbedtls_test_buffer
This error occurs when free space in the buffer is in the middle (the buffer has come full circle) and function mbedtls_test_buffer_put is called. Then the arguments for memcpy are calculated incorrectly and program ends with segmentation fault

031827feba Add mbedtls_mock_socket to SSL unit tests
In a unit test we want to avoid accessing the network. To test the
handshake in the unit test suite we need to implement a connection
between the server and the client. This socket implementation uses
two ring buffers to mock the transport layer.

f9b3303eb9 Introduce specific error for ver/cfg mismatch on deserialization
This commit introduces a new SSL error code

  `MBEDTLS_ERR_SSL_VERSION_MISMATCH`

which can be used to indicate operation failure due to a
mismatch of version or configuration.

It is put to use in the implementation of `mbedtls_ssl_session_load()`
to signal the attempt to de-serialize a session which has been serialized
in a build of Mbed TLS using a different version or configuration.

fe1275e3fe Improve test for detection of ver/cfg corruption in serialized data
This commit improves the test exercising the behaviour of
session deserialization when facing an unexpected version
or config, by testing ver/cfg corruption at any bit in the
ver/cfg header of the serialized data; previously, it had
only tested the first bit of each byte.

aa75583ced Re-enable test that now works with new format
Previously the test didn't work because of embedded pointer values that
are not predictable. Now it works as we no longer serialize such values.

ee13a732d6 Fix serialization tests for !SSL_KEEP_PEER_CERT
The chosen fix matches what's currently done in the baremetal branch - except
the `#ifdef` have been adapted because now in baremetal the digest is not kept
if renegotiation is disabled.

686adb4d54 Normalize spelling to serialiZation
We have explicit recommendations to use US spelling for technical writing, so
let's apply this to code as well for uniformity. (My fingers tend to prefer UK
spelling, so this needs to be fixed in many places.)
