Add MBEDTLS_ERR_XXX_HW_ACCEL_FAILED error codes for all cryptography
modules where the software implementation can be replaced by a hardware
implementation.
This does not include the individual message digest modules since they
currently have no way to return error codes.
This does include the higher-level md, cipher and pk modules since
alternative implementations and even algorithms can be plugged in at
runtime.
The commit f5bf7189d303e602992c750c09e429e23c7b2abf made the AES
functions mbedtls_aes_encrypt and mbedtls_aes_decrypt static, changing
the library's API.
This commit reverts this.
The functions mbedtls_aes_decrypt and mbedtls_aes_encrypt have been
superseded by mbedtls_aes_internal_decrypt and
mbedtls_aes_internal_encrypt, respectively. Alternative
implementations should now only replace the latter, and leave the
maintenance wrapper definitions of the former untouched.
This commit clarifies this in the documentation of the respective
configuration options MBEDTLS_AES_DECRYPT_ALT and
MBEDTLS_AES_ENCRYPT_ALT.
This patch modifies the following 2 functions in the AES module to
change the return type from void to int:
* mbedtls_aes_encrypt() -> mbedtls_internal_aes_encrypt()
* mbedtls_aes_decrypt() -> mbedtls_internal_aes_decrypt()
This change is necessary to allow users of MBEDTLS_AES_ALT,
MBEDTLS_AES_DECRYPT_ALT and MBEDTLS_AES_ENCRYPT_ALT to return an error
code when replacing the default with their own implementation, e.g.
a hardware crypto accelerator.
