| Configuration file split |
| ======================== |
| |
| ## Why splitting the configuration file? |
| |
| The objective of the repository split is to reach the point where in Mbed TLS |
| all the cryptography code and its tests are located in a tf-psa-crypto |
| directory that just contains the TF-PSA-Crypto repository as a submodule. |
| The cryptography APIs exposed by Mbed TLS are just the TF-PSA-Crypto ones. |
| Mbed TLS relies solely on the TF-PSA-Crypto build system to build its |
| cryptography library and its tests. |
| |
| The TF-PSA-Crypto configuration file `tf_psa_crypto_config.h` configures |
| entirely the cryptography interface exposed by Mbed TLS through TF-PSA-Crypto. |
| Mbed TLS configuration is splitted in two files: `mbedtls_config.h` for TLS and |
| x509, `tf_psa_crypto_config.h` for the cryptography. |
| |
| ## How do we split the configuration file? |
| |
| We extend the so called PSA cryptographic configuration scheme based on |
| `mbedtls_config.h` and `crypto_config.h`. The configuration file `crypto_config.h` |
| is extended to become the TF-PSA-Crypto configuration file, `mbedtls_config.h` |
| becomes the configuration file for the TLS and x509 libraries. All the options |
| to select the cryptographic mechanisms and to configure their implementation |
| are moved from `mbedtls_config.h` to `(tf_psa_)crypto_config.h`. |
| |
| The configuration options that are relevant to both Mbed TLS and TF-PSA-Crypto |
| like platform or system ones are moved to `(tf_psa_)crypto_config.h`. That way |
| they are available in both repositories (as Mbed TLS includes |
| `tf_psa_crypto_config.h`) without duplication. Later, we may duplicate or |
| create aliases for some of them to align with the naming conventions of the |
| repositories. |
| |
| The layout of options into sections in `mbedtls_config.h` does not suit |
| TF-PSA-Crypto well thus the configuration options `tf_psa_crypto_config.h` are |
| organized into different sections (see below). |
| |
| ## Configuration files and `config.py` |
| |
| Each repository contains a `config.py` script to create and modify |
| configurations. |
| |
| In Mbed TLS, `config.py` handles both `mbedtls_config.h` and |
| `tf_psa_crypto_config.h`. It can set or unset TLS, x509 and cryptographic |
| configuration options without having to specify the configuration file the |
| options belong to. Commands like full and baremetal affect both configuration |
| files. |
| |
| In TF-PSA-Crypto, `config.py` addresses only `tf_psa_crypto_config.h`. |
| |
| ## Sections in `tf_psa_crypto_config.h` |
| |
| The `tf_psa_crypto_config.h` configuration file is organized into eight |
| sections. |
| |
| The pre-split `mbedtls_config.h` configuration file contains configuration |
| options that apply to the whole code base (TLS, x509, crypto and tests) mostly |
| related to the platform abstraction layer and testing. In |
| `tf_psa_crypto_config.h` these configurations options are organized into two |
| sections, one for the platform abstraction layer options and one for the others, |
| respectively named "Platform abstraction layer" and |
| "General and test configuration options". |
| |
| Then, the "Cryptographic mechanism selection (PSA API)" section is the |
| equivalent of the pre-split `crypto_config.h` configuration file containing the |
| PSA_WANT_ prefixed macros. |
| |
| The following section named "Cryptographic mechanism selection (extended API)" |
| contains the configuration options for the cryptography mechanisms that are not |
| yet part of the PSA cryptography API (like LMS or PK). |
| |
| It is followed by the "Data format support" section that contains configuration |
| options of utilities related to various data formats (like base64 or ASN1 APIs). |
| These utilities aim to facilitate the usage of the PSA cryptography API in other |
| cryptography projects. |
| |
| Compared to Mbed TLS, the cryptography code in TF-PSA-Crypto is not located |
| in a single directory but split between the PSA core (core directory) and the |
| PSA builtin drivers (drivers/builtin/src directory). This is reflected in |
| `tf_psa_crypto_config.h` with two sections respectively named "PSA core" and |
| "Builtin drivers". |
| |
| Finally, the last section named "Legacy cryptography" contains the configuration |
| options that will eventually be removed as duplicates of PSA_WANT_\* and |
| MBEDTLS_PSA_ACCEL_\* configuration options. |
| |
| By contrast to `mbedtls_config.h`, `tf_psa_crypto_config.h` does not contain a |
| section like the "Module configuration options" one containing non boolean |
| configuration options. The configuration options that are not boolean are |
| located in the same section as the boolean option they are associated to. |
| |
| Open question: do we group them into a subsection? |
| |
