Detect attempts to do ECDSA with a Montgomery curve in psa_sign_hash_start() and psa_verify_hash_start(), whereas before start() would succeed and complete() would fail. This avoids an inconsistency between psa_sign_hash() and psa_sign_hash_start() that would be annoying to handle in test_suite_psa_crypto_op_fail. Signed-off-by: Gilles Peskine <[email protected]>

Mbed-TLS/mbedtls-framework#104 fixes a bug whereby some negative tests were always skipped (because they were generated with incorrect dependencies). These test cases fail because the test code is more strict about error behavior than the library. Make the library detect some errors earlier to reconcile it with the test code.
Once this is merged, the CI on Mbed-TLS/mbedtls-framework#104 should pass.
