We had a message in the data file, and were computing its hash in the
test function. It is more efficient (and simpler when it comes to
dependencies) to directly have the message hash in the data file.
It was probably this way because some test vectors provide the message
for the sake of all-in-one implementation that hash-and-sign at once.
But our API gets a hash as the input and signs it. In unit tests, this
should be reflected in the signature of the test function, which should
take a hash as input.
The changes to the .data file were done using the following python
script:
import hashlib
suite = 'pkcs1_v15'
functions = {
'pkcs1_rsassa_v15_sign': (10, 12),
'pkcs1_rsassa_v15_verify': (6, 8),

Having the whole .function file depend on SHA-1 was wrong: dependencies
in .function files are for compile-time dependencies all functions in
this file build just fine without SHA-1. It's just some tests cases that
do need SHA-1 at runtime, use dependencies on those specific tests in
the .data file then.
This reduces the number of cases skipped in this test suite in
test_psa_crypto_config_accel_hash_use_psa from 28 (all of them) down to
12 (those that actually use SHA-1 as opposed to no hash).

While at it, also fix buffer size for functions that already depend on
USE_PSA: it should be PSA_HASH_MAX_SIZE for functions that always use
PSA, and the new macro MBEDTLS_USE_PSA_MD_MAX_SIZE for functions that
use it or not depending on USE_PSA.
The only case where MBEDTLS_MD_MAX_SIZE is OK is when the function
always uses MD - currently this is the case with
pk_sign_verify_restart() as it is incompatible with USE_PSA anyway.
Signed-off-by: Manuel Pégourié-Gonnard <manuel.pegourie-gonnard@arm.com>
When MD is only used to compute a size, use md_internal.h instead.
When it's actually used to compute a hash, mark the test function as
depending on it. This is probably suboptimal in the long run, and we
might want to either adapt the code so that it can use PSA Crypto
instead, or just pre-compute the hash in the test data.

We want to check:
1. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE (the output fits
if the caller uses the key-specific buffer size macro)
2. actual output <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE (the output fits
if the caller uses the generic buffer size macro)
3. PSA_RAW_KEY_AGREEMENT_OUTPUT_SIZE <= PSA_RAW_KEY_AGREEMENT_OUTPUT_MAX_SIZE
(consistency in the calculation)
We were only testing (1) and (2). Test (3) as well. (1) and (3) together
imply (2) so there's no need to test (2).

For multipart encrpytion, call psa_cipher_finish(). This is not actually
necessary for non-pathological implementations of ECB (the only currently
supported IV-less cipher algorithm) because it requires the input to be a
whole number of blocks and non-pathological implementations emit the output
block from update() as soon as an input block is available. But in principle
a driver could delay output and thus require a call to finish().

Validate the size macros directly from the output length in the test data,
rather than using the value returned by the library. This is equivalent
since the value returned by the library is checked to be identical.
Enforce that SIZE() <= MAX_SIZE(), in addition to length <= SIZE(). This is
stronger than the previous code which merely enforced length <= SIZE() and
length <= MAX_SIZE().

We test some configurations using drivers where the driver doesn't

compound algorithms that use those hashes. Until this is fixed,
in those configurations, don't try to actually perform operations.
The built-in implementation of asymmetric algorithms that use a
hash internally only dispatch to the internal md module, not to
PSA. Until this is supported, don't try to actually perform
operations when the operation is built-in and the hash isn't.

Due to standard structure padding, the structure size does not change
unless alignment is 1-byte (instead of 2-byte or more)
Note: existing application use which accesses the struct member

but not compatible on big-endian platforms. The enum values for
the lower byte of MBEDTLS_SSL_VERSION_TLS1_2 and of
MBEDTLS_SSL_VERSION_TLS1_3 matches MBEDTLS_SSL_MINOR_VERSION_3 and
MBEDTLS_SSL_MINOR_VERSION_4, respectively.
Note: care has been taken to preserve serialized session format,
