08f34656cb Return the same error in multipart and single shot AEAD
psa_aead_encrypt_setup() and psa_aead_decrypt_setup() were returning
PSA_ERROR_INVALID_ARGUMENT, while the same failed checks were producing
PSA_ERROR_NOT_SUPPORTED if they happened in psa_aead_encrypt() or
psa_aead_decrypt().

The PSA Crypto API 1.1 spec will specify PSA_ERROR_INVALID_ARGUMENT
in the case that the supplied algorithm is not an AEAD one.

Also move these shared checks to a helper function, to reduce code
duplication and ensure that the functions remain in sync.

d69da6c3c3 Improve PSA error return code
psa_key_derivation_output_key: prioritize BAD_STATE over NOT_PERMITTED

If psa_key_derivation_output_key() is called on an operation which hasn't been
set up or which has been aborted, return PSA_ERROR_BAD_STATE. Only return
PSA_ERROR_NOT_PERMITTED if the operation state is ok for
psa_key_derivation_input_bytes() or psa_key_derivation_output_bytes() but not
ok to output a key.

Ideally psa_key_derivation_output_key() would return PSA_ERROR_NOT_PERMITTED
only when psa_key_derivation_output_bytes() is possible, but this is clumsier
to implement.

f7b4137e69 Untangle PSA_ALG_IS_HASH_AND_SIGN and PSA_ALG_IS_SIGN_HASH
The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).

In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.

Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.
```

f28261fc14 Remove output buffer limitation for PSA with GCM.
The requirement of minimum 15 bytes for output buffer in
psa_aead_finish() and psa_aead_verify() does not apply
to the built-in implementation of the GCM.

Alternative implementations are expected to verify the
length of the provided output buffers and to return
the MBEDTLS_ERR_GCM_BUFFER_TOO_SMALL in case the
buffer length is too small.

424fa93efd psa: Support RSA signature without MBEDTLS_GENPRIME
On space-constrained platforms, it is a useful configuration to be able
to import/export and perform RSA key pair operations, but to exclude RSA
key generation, potentially saving flash space. It is not possible to
express this with the PSA_WANT_ configuration system at the present
time. However, in previous versions of Mbed TLS (v2.24.0 and earlier) it
was possible to configure a software PSA implementation which was
capable of making RSA signatures but not capable of generating RSA keys.
To do this, one unset MBEDTLS_GENPRIME.

Since the addition of MBEDTLS_PSA_BUILTIN_KEY_TYPE_RSA_KEY_PAIR, this
expressivity was lost. Expressing that you wanted to work with RSA key
pairs forced you to include the ability to generate key pairs as well.

Change psa_crypto_rsa.c to only call mbedtls_rsa_gen_key() if
MBEDTLS_GENPRIME is also set. This restores the configuration behavior
present in Mbed TLS v2.24.0 and earlier versions.

It left as a future exercise to add the ability to PSA to be able to
express a desire for a software or accelerator configuration that
includes RSA key pair operations, like signature, but excludes key pair
generation.

Without this change, linker errors will occur when attempts to call,
which doesn't exist when MBEDTLS_GENPRIME is unset.
    psa_crypto_rsa.c.obj: in function `rsa_generate_key':
    psa_crypto_rsa.c:320: undefined reference to `mbedtls_rsa_gen_key'

8af5c5c7de Be explicit about why the zero-length check is there
Since a valid mac operation context would guarantee that the stored
mac size is >= 4, it wasn't immediately obvious that the zero-length
check is meant for static analyzers and a bit of robustness.

72f736a191 Move is_sign and mac_size checking back to PSA core scope
It makes sense to do the length checking in the core rather than expect
each driver to deal with it themselves. This puts the onus on the core to
dictate which algorithm/key combinations are valid before calling a driver.

Additionally, this commit also updates the psa_mac_sign_finish function
to better deal with output buffer sanitation, as per the review comments
on #4247.

a1684f42d3 PSA: Reject curves that are not enabled in the PSA configuration
If an elliptic curve was enabled in the Mbed TLS classic API (#define
MBEDTLS_ECP_DP_xxx), but not enabled in the PSA configuration (#define
PSA_WANT_ECC_xxx), it would still work if you tried to use it through
PSA.

This is generally benign, but could be a security issue if you want to
disable a curve in PSA for some security reason (such as a known bug
in its implementation, which may not matter in the classic API if Mbed
TLS is running in a secure enclave and is only reachable from
untrusted callers through the PSA API). More urgently, this broke
test_suite_psa_crypto_not_supported.generated.

So if a curve is not enabled in the PSA configuration, ensure that
it's treated as unsupported through the PSA software implementation.

anymore at this point.

bb9cbc7a23 psa: ecdsa: Prefer NOT_SUPPORTED error code
When ECDSA is not supported by the library, prefer
to return NOT_SUPPORTED than INVALID_ARGUMENT when
asked for an ECDSA signature.

9103d490e8 psa: ecdsa: Rework deterministic support check
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.
