Crypto: Align PSA headers entirely to Mbed TLS 3.6.0
This also simplifies the client attributes translation between
client view and service view and reorganized how the Mbed TLS
config files are handled between NS/S (client/service) sides.
At the same time, perform a CMake targets refactoring to allow
exporting a client side view of the config files.

+ * \brief This function performs an AES-CTR encryption or decryption
+ * operation.
+ *
+ * Due to the nature of CTR, you must use the same key schedule
+ * for both encryption and decryption operations. Therefore, you
+ * must use the context initialized with mbedtls_aes_setkey_enc()
+ * for both #MBEDTLS_AES_ENCRYPT and #MBEDTLS_AES_DECRYPT.
+ *
+ * \warning You must never reuse a nonce value with the same key. Doing so
+ * would void the encryption for the two messages encrypted with
+ * the same nonce and key.
+ *
+ * There are two common strategies for managing nonces with CTR:
+ *
+ * 1. You can handle everything as a single message processed over
+ * successive calls to this function. In that case, you want to
+ * set \p nonce_counter and \p nc_off to 0 for the first call, and
+ * then preserve the values of \p nonce_counter, \p nc_off and \p
+ * stream_block across calls to this function as they will be
+ * updated by this function.
+ *
+ * With this strategy, you must not encrypt more than 2**128
+ * blocks of data with the same key.
+ *
+ * 2. You can encrypt separate messages by dividing the \p
+ * nonce_counter buffer in two areas: the first one used for a
+ * per-message nonce, handled by yourself, and the second one
+ * updated by this function internally.
+ *
+ * For example, you might reserve the first 12 bytes for the
+ * per-message nonce, and the last 4 bytes for internal use. In that
+ * case, before calling this function on a new message you need to
+ * set the first 12 bytes of \p nonce_counter to your chosen nonce
+ * value, the last 4 to 0, and \p nc_off to 0 (which will cause \p
+ * stream_block to be ignored). That way, you can encrypt at most
+ * 2**96 messages of up to 2**32 blocks each with the same key.
+ *
+ * The per-message nonce (or information sufficient to reconstruct
+ * it) needs to be communicated with the ciphertext and must be unique.
+ * The recommended way to ensure uniqueness is to use a message
+ * counter. An alternative is to generate random nonces, but this
+ * limits the number of messages that can be securely encrypted:
+ * for example, with 96-bit random nonces, you should not encrypt
+ * more than 2**32 messages with the same key.
+ *
+ * Note that for both strategies, sizes are measured in blocks and
+ * that an AES block is 16 bytes.
+ *
+ * \warning Upon return, \p stream_block contains sensitive data. Its
+ * content must not be written to insecure storage and should be
+ * securely discarded as soon as it's no longer needed.
+ *
+ * \param ctx The AES context to use for encryption or decryption.
+ * It must be initialized and bound to a key.
+ * \param length The length of the input data.
+ * \param nc_off The offset in the current \p stream_block, for
+ * resuming within the current cipher stream. The
+ * offset pointer should be 0 at the start of a stream.
+ * It must point to a valid \c size_t.
+ * \param nonce_counter The 128-bit nonce and counter.
+ * It must be a readable-writeable buffer of \c 16 Bytes.
+ * \param stream_block The saved stream block for resuming. This is
+ * overwritten by the function.
+ * It must be a readable-writeable buffer of \c 16 Bytes.
+ * \param input The buffer holding the input data.

+ * \param tag_may_val The desired value of each ASN.1 tag found in the

+ *
+ * \warning You must never reuse a nonce value with the same key. Doing so
+ * would void the encryption for the two messages encrypted with
+ * the same nonce and key.
+ *
+ * There are two common strategies for managing nonces with CTR:
+ *
+ * 1. You can handle everything as a single message processed over
+ * successive calls to this function. In that case, you want to
+ * set \p nonce_counter and \p nc_off to 0 for the first call, and
+ * then preserve the values of \p nonce_counter, \p nc_off and \p
+ * stream_block across calls to this function as they will be
+ * updated by this function.
+ *
+ * With this strategy, you must not encrypt more than 2**128
+ * blocks of data with the same key.
+ *
+ * 2. You can encrypt separate messages by dividing the \p
+ * nonce_counter buffer in two areas: the first one used for a
+ * per-message nonce, handled by yourself, and the second one
+ * updated by this function internally.
+ *
+ * For example, you might reserve the first \c 12 Bytes for the
+ * per-message nonce, and the last \c 4 Bytes for internal use.
+ * In that case, before calling this function on a new message you
+ * need to set the first \c 12 Bytes of \p nonce_counter to your
+ * chosen nonce value, the last four to \c 0, and \p nc_off to \c 0
+ * (which will cause \p stream_block to be ignored). That way, you
+ * can encrypt at most \c 2**96 messages of up to \c 2**32 blocks
+ * each with the same key.
+ *
+ * The per-message nonce (or information sufficient to reconstruct
+ * it) needs to be communicated with the ciphertext and must be
+ * unique. The recommended way to ensure uniqueness is to use a
+ * message counter. An alternative is to generate random nonces,
+ * but this limits the number of messages that can be securely
+ * encrypted: for example, with 96-bit random nonces, you should
+ * not encrypt more than 2**32 messages with the same key.
+ *
+ * Note that for both strategies, sizes are measured in blocks and
+ * that a CAMELLIA block is \c 16 Bytes.
+ *
+ * \warning Upon return, \p stream_block contains sensitive data. Its
+ * content must not be written to insecure storage and should be
+ * securely discarded as soon as it's no longer needed.
+ *
+ * \param ctx The CAMELLIA context to use. This must be initialized
+ * and bound to a key.
+ * \param length The length of the input data \p input in Bytes.
+ * Any value is allowed.
+ * \param nc_off The offset in the current \p stream_block (for resuming
+ * within current cipher stream). The offset pointer to
+ * should be \c 0 at the start of a stream. It is updated
+ * at the end of this call.
+ * \param nonce_counter The 128-bit nonce and counter. This must be a read/write
+ * buffer of length \c 16 Bytes.
+ * \param stream_block The saved stream-block for resuming. This must be a
+ * read/write buffer of length \c 16 Bytes.
+ * \param input The input data stream. This must be a readable buffer of
+ * size \p length Bytes.

+ * You may call this function zero, one or more times
+ * to pass successive parts of the input: the plaintext to
+ * encrypt, or the ciphertext (not including the tag) to
+ * decrypt. After the last part of the input, call
+ * mbedtls_ccm_finish(). The lengths \p input_len of the
+ * data parts should eventually add up exactly to the
+ * plaintext length \c plaintext_len passed to
+ * mbedtls_ccm_set_lengths().
+ *
+ * This function may produce output in one of the following
+ * ways:
+ * - Immediate output: the output length is always equal
+ * to the input length.
+ * - Buffered output: except for the last part of input data,
+ * the output consists of a whole number of 16-byte blocks.
+ * If the total input length so far (not including
+ * associated data) is 16 \* *B* + *A* with *A* < 16 then
+ * the total output length is 16 \* *B*.
+ * For the last part of input data, the output length is
+ * equal to the input length plus the number of bytes (*A*)
+ * buffered in the previous call to the function (if any).
+ * The function uses the plaintext length
+ * \c plaintext_len passed to mbedtls_ccm_set_lengths()
+ * to detect the last part of input data.
+ *
+ * In particular:
+ * - It is always correct to call this function with
+ * \p output_size >= \p input_len + 15.
+ * - If \p input_len is a multiple of 16 for all the calls
+ * to this function during an operation (not necessary for

+ * =\p input_len.

+/**
+ * \file mbedtls/config_adjust_legacy_crypto.h
+ * \brief Adjust legacy configuration configuration
+ *
+ * Automatically enable certain dependencies. Generally, MBEDLTS_xxx
+ * configurations need to be explicitly enabled by the user: enabling
+ * MBEDTLS_xxx_A but not MBEDTLS_xxx_B when A requires B results in a
+ * compilation error. However, we do automatically enable certain options
+ * in some circumstances. One case is if MBEDTLS_xxx_B is an internal option
+ * used to identify parts of a module that are used by other module, and we
+ * don't want to make the symbol MBEDTLS_xxx_B part of the public API.
+ * Another case is if A didn't depend on B in earlier versions, and we
+ * want to use B in A but we need to preserve backward compatibility with
+ * configurations that explicitly activate MBEDTLS_xxx_A but not
+ * MBEDTLS_xxx_B.

+ * The security strength as defined in NIST SP 800-90A is
+ * 128 bits when AES-128 is used (\c MBEDTLS_CTR_DRBG_USE_128_BIT_KEY enabled)
+ * and 256 bits otherwise, provided that #MBEDTLS_CTR_DRBG_ENTROPY_LEN is

+/**
+ * \file dhm.h
+ *
+ * \brief This file contains Diffie-Hellman-Merkle (DHM) key exchange
+ * definitions and functions.
+ *
+ * Diffie-Hellman-Merkle (DHM) key exchange is defined in
+ * <em>RFC-2631: Diffie-Hellman Key Agreement Method</em> and
+ * <em>Public-Key Cryptography Standards (PKCS) #3: Diffie
+ * Hellman Key Agreement Standard</em>.
+ *
+ * <em>RFC-3526: More Modular Exponential (MODP) Diffie-Hellman groups for
+ * Internet Key Exchange (IKE)</em> defines a number of standardized
+ * Diffie-Hellman groups for IKE.
+ *
+ * <em>RFC-5114: Additional Diffie-Hellman Groups for Use with IETF
+ * Standards</em> defines a number of standardized Diffie-Hellman
+ * groups that can be used.
+ *
+ * \warning The security of the DHM key exchange relies on the proper choice
+ * of prime modulus - optimally, it should be a safe prime. The usage
+ * of non-safe primes both decreases the difficulty of the underlying
+ * discrete logarithm problem and can lead to small subgroup attacks
+ * leaking private exponent bits when invalid public keys are used
+ * and not detected. This is especially relevant if the same DHM
+ * parameters are reused for multiple key exchanges as in static DHM,
+ * while the criticality of small-subgroup attacks is lower for
+ * ephemeral DHM.
+ *
+ * \warning For performance reasons, the code does neither perform primality
+ * nor safe primality tests, nor the expensive checks for invalid
+ * subgroups. Moreover, even if these were performed, non-standardized
+ * primes cannot be trusted because of the possibility of backdoors
+ * that can't be effectively checked for.
+ *
+ * \warning Diffie-Hellman-Merkle is therefore a security risk when not using
+ * standardized primes generated using a trustworthy ("nothing up
+ * my sleeve") method, such as the RFC 3526 / 7919 primes. In the TLS
+ * protocol, DH parameters need to be negotiated, so using the default
+ * primes systematically is not always an option. If possible, use
+ * Elliptic Curve Diffie-Hellman (ECDH), which has better performance,
+ * and for which the TLS protocol mandates the use of standard
+ * parameters.

+ * trust-worthy procedure:
+ * - Fix N in { 2048, 3072, 4096, 6144, 8192 } and consider the N-bit number
+ * the first and last 64 bits are all 1, and the remaining N - 128 bits of
+ * which are 0x7ff...ff.
+ * - Add the smallest multiple of the first N - 129 bits of the binary expansion
+ * of pi (for RFC 5236) or e (for RFC 7919) to this intermediate bit-string
+ * such that the resulting integer is a safe-prime.
+ * - The result is the respective RFC 3526 / 7919 prime, and the corresponding
+ * generator is always chosen to be 2 (which is a square for these prime,
+ * hence the corresponding subgroup has order (p-1)/2 and avoids leaking a
+ * bit in the private exponent).

+ * - The RFC specifies the Signed Data type can contain multiple X.509 or PKCS #6 extended
+ * certificates. In Mbed TLS, this list can only contain 0 or 1 certificates
+ * and they must be in X.509 format.
+ * - The RFC specifies the Signed Data type can contain
+ * certificate-revocation lists (CRLs). This implementation has no support
+ * for CRLs so it is assumed to be an empty list.
+ * - The RFC allows for SignerInfo structure to optionally contain
+ * unauthenticatedAttributes and authenticatedAttributes. In Mbed TLS it is

+ * Reference: RFC 9146 (or draft-ietf-tls-dtls-connection-id-05
+ * https://tools.ietf.org/html/draft-ietf-tls-dtls-connection-id-05
+ * for legacy version)
+ *
+ * The DTLS CID extension allows the reliable association of
+ * DTLS records to DTLS connections across changes in the
+ * underlying transport (changed IP and Port metadata) by
+ * adding explicit connection identifiers (CIDs) to the
+ * headers of encrypted DTLS records. The desired CIDs are
+ * configured by the application layer and are exchanged in
+ * new `ClientHello` / `ServerHello` extensions during the
+ * handshake, where each side indicates the CID it wants the
+ * peer to use when writing encrypted messages. The CIDs are
+ * put to use once records get encrypted: the stack discards
+ * any incoming records that don't include the configured CID
+ * in their header, and adds the peer's requested CID to the
+ * headers of outgoing messages.
+ *
+ * This API enables or disables the use of the CID extension
+ * in the next handshake and sets the value of the CID to
+ * be used for incoming messages.
+ *
+ * \param ssl The SSL context to configure. This must be initialized.
+ * \param enable This value determines whether the CID extension should
+ * be used or not. Possible values are:
+ * - MBEDTLS_SSL_CID_ENABLED to enable the use of the CID.
+ * - MBEDTLS_SSL_CID_DISABLED (default) to disable the use
+ * of the CID.
+ * \param own_cid The address of the readable buffer holding the CID we want
+ * the peer to use when sending encrypted messages to us.
+ * This may be \c NULL if \p own_cid_len is \c 0.
+ * This parameter is unused if \p enable is set to
+ * MBEDTLS_SSL_CID_DISABLED.
+ * \param own_cid_len The length of \p own_cid.
+ * This parameter is unused if \p enable is set to
+ * MBEDTLS_SSL_CID_DISABLED.
+ *
+ * \note The value of \p own_cid_len must match the value of the
+ * \c len parameter passed to mbedtls_ssl_conf_cid()
+ * when configuring the ::mbedtls_ssl_config that \p ssl
+ * is bound to.
+ *
+ * \note This CID configuration applies to subsequent handshakes
+ * performed on the SSL context \p ssl, but does not trigger
+ * one. You still have to call `mbedtls_ssl_handshake()`
+ * (for the initial handshake) or `mbedtls_ssl_renegotiate()`
+ * (for a renegotiation handshake) explicitly after a
+ * successful call to this function to run the handshake.
+ *
+ * \note This call cannot guarantee that the use of the CID
+ * will be successfully negotiated in the next handshake,
+ * because the peer might not support it. Specifically:
+ * - On the Client, enabling the use of the CID through
+ * this call implies that the `ClientHello` in the next
+ * handshake will include the CID extension, thereby
+ * offering the use of the CID to the server. Only if
+ * the `ServerHello` contains the CID extension, too,
+ * the CID extension will actually be put to use.
+ * - On the Server, enabling the use of the CID through
+ * this call implies that the server will look for
+ * the CID extension in a `ClientHello` from the client,
+ * and, if present, reply with a CID extension in its
+ * `ServerHello`.
+ *
+ * \note To check whether the use of the CID was negotiated
+ * after the subsequent handshake has completed, please
+ * use the API mbedtls_ssl_get_peer_cid().
+ *
+ * \warning If the use of the CID extension is enabled in this call
+ * and the subsequent handshake negotiates its use, Mbed TLS
+ * will silently drop every packet whose CID does not match
+ * the CID configured in \p own_cid. It is the responsibility
+ * of the user to adapt the underlying transport to take care
+ * of CID-based demultiplexing before handing datagrams to
+ * Mbed TLS.

+ * In nominal conditions (that is, if no error occurs),
+ * the effect of a call to a key creation function in the PSA Cryptography
+ * API with a lifetime that places the key in a secure element is the
+ * following:
+ * -# The core calls psa_drv_se_key_management_t::p_allocate
+ * (or in some implementations
+ * psa_drv_se_key_management_t::p_validate_slot_number). The driver
+ * selects (or validates) a suitable slot number given the key attributes
+ * and the state of the secure element.
+ * -# The core calls a key creation function in the driver.
+ *
+ * The key creation functions in the PSA Cryptography API are:
+ * - psa_import_key(), which causes
+ * a call to `p_allocate` with \p method = #PSA_KEY_CREATION_IMPORT
+ * then a call to psa_drv_se_key_management_t::p_import.
+ * - psa_generate_key(), which causes
+ * a call to `p_allocate` with \p method = #PSA_KEY_CREATION_GENERATE
+ * then a call to psa_drv_se_key_management_t::p_import.
+ * - psa_key_derivation_output_key(), which causes
+ * a call to `p_allocate` with \p method = #PSA_KEY_CREATION_DERIVE
+ * then a call to psa_drv_se_key_derivation_t::p_derive.
+ * - psa_copy_key(), which causes
+ * a call to `p_allocate` with \p method = #PSA_KEY_CREATION_COPY
+ * then a call to psa_drv_se_key_management_t::p_export.
+ *
+ * In case of errors, other behaviors are possible.
+ * - If the PSA Cryptography subsystem dies after the first step,
+ * for example because the device has lost power abruptly,

+ * and re-initialization. Alternatively, after a reset and

+ * was allocated (or validated) instead of calling a key creation function.
+ *
+ * Errors and system resets also have an impact on the driver's persistent

+/** \defgroup driver_derivation Secure Element Key Derivation and Agreement
+ * Key derivation is the process of generating new key material using an
+ * existing key and additional parameters, iterating through a basic
+ * cryptographic function, such as a hash.
+ * Key agreement is a part of cryptographic protocols that allows two parties
+ * to agree on the same key value, but starting from different original key
+ * material.
+ * The flows are similar, and the PSA Crypto Driver Model uses the same functions
+ * for both of the flows.
+ *
+ * There are two different final functions for the flows,
+ * `psa_drv_se_key_derivation_derive` and `psa_drv_se_key_derivation_export`.
+ * `psa_drv_se_key_derivation_derive` is used when the key material should be
+ * placed in a slot on the hardware and not exposed to the caller.
+ * `psa_drv_se_key_derivation_export` is used when the key material should be
+ * returned to the PSA Cryptographic API implementation.
+ *
+ * Different key derivation algorithms require a different number of inputs.
+ * Instead of having an API that takes as input variable length arrays, which
+ * can be problematic to manage on embedded platforms, the inputs are passed
+ * to the driver via a function, `psa_drv_se_key_derivation_collateral`, that
+ * is called multiple times with different `collateral_id`s. Thus, for a key
+ * derivation algorithm that required 3 parameter inputs, the flow would look
+ * something like:
+ * ~~~~~~~~~~~~~{.c}
+ * psa_drv_se_key_derivation_setup(kdf_algorithm, source_key, dest_key_size_bytes);
+ * psa_drv_se_key_derivation_collateral(kdf_algorithm_collateral_id_0,

+ * p_collateral_2,
+ * collateral_2_size);
+ * psa_drv_se_key_derivation_derive();
+ * ~~~~~~~~~~~~~
+ *

+ * ~~~~~~~~~~~~~{.c}

+ * <h3>Design notes about multipart operation structures</h3>
+ *
+ * For multipart operations without driver delegation support, each multipart
+ * operation structure contains a `psa_algorithm_t alg` field which indicates
+ * which specific algorithm the structure is for. When the structure is not in
+ * use, `alg` is 0. Most of the structure consists of a union which is
+ * discriminated by `alg`.
+ *
+ * For multipart operations with driver delegation support, each multipart
+ * operation structure contains an `unsigned int id` field indicating which
+ * driver got assigned to do the operation. When the structure is not in use,
+ * 'id' is 0. The structure contains also a driver context which is the union
+ * of the contexts of all drivers able to handle the type of multipart
+ * operation.
+ *
+ * Note that when `alg` or `id` is 0, the content of other fields is undefined.
+ * In particular, it is not guaranteed that a freshly-initialized structure
+ * is all-zero: we initialize structures to something like `{0, 0}`, which
+ * is only guaranteed to initializes the first member of the union;
+ * GCC and Clang initialize the whole structure to 0 (at the time of writing),
+ * but MSVC and CompCert don't.
+ *
+ * In Mbed TLS, multipart operation structures live independently from
+ * the key. This allows Mbed TLS to free the key objects when destroying
+ * a key slot. If a multipart operation needs to remember the key after
+ * the setup function returns, the operation structure needs to contain a
+ * copy of the key.

Subject: [PATCH 1/6] Add TF-M Builtin Key Loader driver entry points
-TF-M requires a mechanism to leverage the drivers and builtin keys
-at the same time to allow for "transparent builtin keys". More details
-are in the TF-M design doc. Provide directly the wrappers instead of
-modifying the autogen scripts, for the time being.
