Fix likely harmless undefined behavior in cipher tests pointed out by
UBSan with recent compilers (e.g. Clang 10). When the complete output
is empty, the output buffer is NULL. Adding an integer to a null
pointer is undefined behavior even when the integer is 0, so make a
special case for that.

Replace MBEDTLS_* config options for which there is
an associated PSA_WANT_* to the PSA_WANT_* one. That
way the tests are also run when the dependency is
provided by a driver.

Generate test cases for all algorithms without parameters. Only the encoding
of the algorithm in the key metadata is covered: the test keys are not of a
type that permits the algorithm to be used in an operation.
This commit only covers algorithms without parameters. A subsequent commit
will generate algorithms with parameters.

Generate test cases for all key types. These test cases cover the key
representation (checked with export) and the encoding of the key type and

Start generating storage format test cases. This commit introduces two test
data files: test_suite_psa_crypto_storage_format.v0.data for reading keys in
storage format version 0 (the current version at this time), and
test_suite_psa_crypto_storage_format.current.data for saving keys in the
current format (version 0 at this time).
This commit kicks off the test case generation with test cases to exercise
the encoding of usage flags. Subsequent commits will cover other aspects of
keys.

Save tests are for forward compatibility: import a key in the current format
and check that it has the expected storage format so that future versions
will still be able to read it.
Read tests are for backward compatibility: read a key in the format of a
past version (injected into storage) and check that this version can use it.
Exercise the key unless it is meant to test metadata storage only.

Printf could potentially produce 2 64 bit numbers here when there is

When ECDSA is not supported by the library, prefer
to return NOT_SUPPORTED than INVALID_ARGUMENT when
asked for an ECDSA signature.
Signed-off-by: Ronald Cron <ronald.cron@arm.com>
Move the check that ECDSA is supported from the
caller of the function responsible for Mbed TLS
ECDSA signatures to this function, namely
mbedtls_psa_ecdsa_sign_hash().
This makes the caller code more readable and is
more aligned with what is expected from a
sign_hash() PSA driver entry point.
Add a negative test case where a deterministic
ECDSA signature is requested while the library
does not support deterministic ECDSA.

Reworked the validation of MAC algorithm with the used key type by
introducing psa_mac_key_can_do, which guarantees that PSA_MAC_LENGTH can
be called successfully after validation of the algorithm and key type.
This means psa_get_mac_output_length is no longer required.

Marked dirty memory ends up in the result buffer after encoding (due to
the input having been marked dirty), and then the final comparison
to make sure that we got what we expected was triggering the constant

Fix sloppy wording around stricly less-than vs less or equal in
comments. Also fix an off-by-one error in a comparison which led to
calling setrlimit if the limit was exactly the minimum required for
the test, which was unnecessary but harmless.

mbedtls_net_poll() and mbedtls_net_recv_timeout() rely on select(),
which represents sets of file descriptors through the fd_set type.
This type cannot hold file descriptors larger than FD_SETSIZE. Make
sure that these functions identify this failure code.
Without a proper range check of the file descriptor in the
mbedtls_net_xxx function, this test fails when running with UBSan:
```
