Gilles Peskine 8133abd746 SSL test programs: always allow building with the PSA external RNG
The SSL test programs can now use the PSA RNG, and the PSA RNG can use
an external RNG. The build conditions hadn't been updated and didn't
cover the case when MBEDTLS_TEST_USE_PSA_CRYPTO_RNG is enabled but
MBEDTLS_USE_PSA_CRYPTO is disabled. Fix this.

Gilles Peskine 38c12fd48e In external_rng tests, disable the entropy module
The point of having an external RNG is that you can disable all
built-in RNG functionality: both the entropy part and the DRBG part.

Gilles Peskine 1dc19ffb29 The PSA external RNG does not require MBEDTLS_USE_PSA_CRYPTO
The dependency is on MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG plus
MBEDTLS_PSA_CRYPTO_C. MBEDTLS_USE_PSA_CRYPTO is irrelevant.

Gilles Peskine b8c484088c Fix psa_destroy_key called after mbedtls_psa_crypto_free
Move the call to destroy the PSK to before freeing the SSL session
data and calling rng_free(), which deinitializes the PSA subsystem.
This particular ordering was chosen to make the ssl_client2 more
similar to ssl_server2. This fixes the client failing on the
psa_destroy_key() call in `ssl-opt.sh -f 'opaque psk on client'`.

Gilles Peskine 8eb2943705 Support mbedtls_psa_get_random() in SSL test programs
The SSL test programs can now use mbedtls_psa_get_random() rather than
entropy+DRBG as a random generator. This happens if
the configuration option MBEDTLS_USE_PSA_CRYPTO is enabled, or if
MBEDTLS_TEST_USE_PSA_CRYPTO_RNG is set at build time.

Gilles Peskine 077599ad85 New test suite for random generation
Test random generation as a whole. This is different from
test_suite_*_drbg and test_suite_entropy, which respectively test PRNG
modules and entropy collection.

Start with basic tests: good-case tests, and do it twice and compare
the results to validate that entropy collection doesn't repeat itself.

Gilles Peskine 2747d7dc60 Duplicate no-DRBG tests: with and without MBEDTLS_USE_PSA_CRYPTO
Whether MBEDTLS_USE_PSA_CRYPTO is enabled makes a significant
difference with respect to how random generators are used (and, for
no-HMAC_DRBG, how ECDSA signature is dispatched), so test both with
and without it.

Gilles Peskine aaedbdcfd6 Refuse reproducible mode with MBEDTLS_USE_PSA_CRYPTO
With MBEDTLS_USE_PSA_CRYPTO, some of the randomness for the TLS
connection is generated inside the PSA crypto subsystem, which has no
reproducible mode. Whether there is a nonzero amount of randomness
coming from inside the PSA subsystem rather than from the random
generator set by mbedtls_ssl_conf_rng() depends on the choice of
cipher suite and other connection parameters as well as the level of
support for MBEDTLS_USE_PSA_CRYPTO. Rather than give unreliable
results, conservatively abort with a clear error message.

Steven Cooreman 64f2773eab Skip tests requiring known entropy for ECJPAKE ALT implementations
These implementations don't necessarily consume entropy the same way the
mbed TLS internal software implementation does, and the 'reference
handshake' test vectors can thus not be applied to an ALT implementation.

Gilles Peskine 3d67365ef7 Add a key_buffer_length output to "get_builtin_key"
While builtin keys will often have a fixed-size context, this is not
necessarily the case, so the "get_builtin_key" entry point needs to
return the size of the actual key context.

Gilles Peskine 1af872d23b Move the fake PSA external RNG to its own header and source files
Move the declaration of the functions needed to use the test
implementation of mbedtls_psa_external_get_random() to a new header
file. Before, they were declared in
tests/include/test/psa_crypto_helpers.h, but this header file can't be
included in sample programs because it also includes headers from the
library directory which is not on the include path for sample
programs.

This fixes the build of the sample programs when
MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG and MBEDTLS_USE_PSA_CRYPTO are
enabled.

Move the implementation of the functions to a separate .c file as
well. This isn't strictly necessary, but makes the structure of the
source code easier to understand.

Gilles Peskine e1d51bd99d Depend on all test headers when building tests
There were explicit dependencies on header files for some test suites,
dating back from when only a few test suites depended on anything in
tests/include. The noted dependencies were still correct, but now that
tests/include is more populated, they were only the tip of the
iceberg. Just keep it simple and depend on all the headers.
