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.

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.

Adds the `mbedtls_` prefix to `test_result_t` and `test_info` and updates
any references to them. This is to follow the naming convention as these are
now declared in a public namespace.

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.

In component_test_no_hmac_drbg, the fact that HMAC_DRBG is disabled
doesn't affect the SSL code, but the fact that deterministic ECDSA is
disabled does. So run some ECDSA-related SSL tests.

- following the removal of the RSA_VALIDATE_RET() to check
the salt length, this test is not necessary/required anymore
- negative salt length are caught later in the function

- removed the check on saltlen > 0 and added tests
positive test cases for this.
- added negative test cases when even saltlen == 0
is not enough. This allowed to uncover an underflow bu
in the slen check (when olen-slen-2 is negative)
- fixed the saltlen check to avoid underflow
- added more test cases where saltlen is the maximum
possible value and one above the maximum possible value
(different hash, different key size)

TEST_ASSERT jumps to the exit label, so it must not be called from
cleanup code executed after the exit label. It's legitimate (and
indeed very common) to call PSA_DONE in cleanup code, so PSA_DONE must
not jump to exit.
Define an auxiliary function test_fail_if_psa_leaking() that calls
test_fail() with the error message provided by
mbedtls_test_helper_is_psa_leaking(). This function currently needs to
be in helpers.function rather than in a PSA-specific helper file
because it calls test_fail which is defined in helpers.function.

Don't microoptimize memory usage in tests: use separate buffers for
the input and the output. Allocate the input buffer dynamically
because the size is a parameter of the test case. Allocate the output
buffer dynamically because it's generally good practice in tests so
that a memory sanitizer can detect a buffer overflow.

When verifying the impact of a forced RNG failure, depend on the built-in
implementation of the algorithm that uses randomization, whether it's
because the algorithm is randomized or because our implementation uses
randomization for (e.g.) blinding. An external implementation could use
its own randomness source which is not affected by the forced failure of
the RNG driver.

Under MBEDTLS_ERR_RSA_RNG_FAILED, add tests where the random generator
failed. This commit tests the following operations:
* psa_generate_random()
* psa_generate_key() for a symmetric key
* Deterministic signatures that use blinding (RSA PKCS#1v1.5,
deterministic ECDSA).
* Randomized signatures (RSA PSS, randomized ECDSA).

To reduce the risk of people accidentally using the test
implementation of mbedtls_psa_external_get_random(), which is
insecure, require the user to explicitly call
mbedtls_test_enable_insecure_external_rng() first.
Disabling the test implementation of mbedtls_psa_external_get_random()
will also allow negative testing for MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG,
which will be added in a subsequent commit.

`tests/scripts/all.sh test_psa_collect_statuses` calls
`tests/scripts/psa_collect_statuses.py` which calls
`make -DRECORD_PSA_STATUS_COVERAGE_LOG` which must generate
`include/test/instrument_record_status.h`.
With the refactoring of `psa_crypto_helpers.{h,c}`, this now
needs to be done before building `psa_crypto_helpers.c`.
Also, remove `include/test/instrument_record_status.h` unconditionally
in `make clean`, which helps keep the build tree clean.

Refactor some PSA test helper functions and macros to avoid depending
on test_info and test_fail inside functions. These identifiers are
only defined in helpers.function, so they're only available in test
suites, and not in test helper modules (tests/src/*.c) which are also
linked into example programs.
This is in preparation for moving function definitions from
psa_crypto_helpers.h to psa_crypto_helpers.c.
No behavior change.

Since 349eadc58faff851ee8dcbb43c702f0ddecfcbb8, test_fail() reports
the first failure. So it's safe to call test_fail() again to report a
cleanup failure when we don't want to potentially erase information
about an earlier failure.
The behavior of mbedtls_test_helper_is_psa_pristine() changes if
test_info.result was neither TEST_RESULT_SUCCESS nor
TEST_RESULT_FAILED, but this should not matter since a skipped test
should not cause mbedtls_test_helper_is_psa_pristine() to fail.

mypy automatically checks the modules when it encounters them as

about encountering them through different paths (via the command line

The test suite assumed that if SHA512 was enabled, then
SHA384 was also available. This is not true. There is
config MBEDTLS_SHA512_NO_SHA384 which allows precisely
to add SHA512 and not SHA384.
This commits adds the necessary `depends_on` clause,
to avoid running the SHA384 tests when config
MBEDTLS_SHA512_NO_SHA384 is set.

- all positibe test cases were sampled from the CAVP test suite
(SigGenPSS_186-2.txt, SigGenPSS_186-3.txt)
Only kept one representative for each triple (modlen, sha, saltlen)
- two extra test cases were added to cover the maximum salt length
(slen=olen-slen-2 and slen=(olen-slen-2)-1)
- in rsa.c, the salt intermediate buffer was too small to cover cases
where slen > hlen. So reworked the code to generate the salt in the
encoded message directly. This has the advantage to remove a memcpy
and a memset.
