Janos Follath 0cbdc61171 Bump version to Mbed TLS 2.25.0
Executed ./scripts/bump_version.sh --version 2.25.0 --so-crypto 6

Increasing the SO version of the crypto library, because the openless
API improvement came with API/ABI incompatibilities. For example
    - the size of psa_key_handle_t changed
    - the type of a parameter in 18 public functions has changed from
      psa_key_handle_t to mbedtls_svc_key_id_t

Work in progress: next steps are to implement and test it.

Compared to the existing non-ext version:

- to separate tag parameter
- explicit output_len parameter

Also, this version will retain support for NIST_KW (hence documents it), while
the non-ext version will lose it in a few commits.

Manuel Pégourié-Gonnard 3ba84d5bd6 Improve documentation of cipher_auth_xxcrypt()
- Document constraints on buffers/pointers NULLability explicitly.
- Simplify terminology around IV/nonce: all AEADs implemented so far call that
  a nonce. Keep the parameter names (iv, iv_len) to avoid having to change the
code (or having different names in the header and C files).
- Align documentation to the code regarding parameter constraints: the
  documentation said the for ciphers with fixed nonce/tag length, the
iv_len/tag_len arguments were ignored, while the code enforced them to be the
expected value. This is more consistent with what's done with GCM/CCM, which
for tag_len for example accept more than one value, but from a relatively
small set, and will return errors for values outside that set. Accepting a
single value is a particular case of that (the set of acceptable value only
has one element).

Don't document behaviour with NIST KW as we're about to change that.

Note: this function is currently only defined if at least one of GCM, CCM or
ChachaPoly is enabled, even though it's supposed to handle NIST KW as well. No
need to fix this as the function will soon no longer support NIST KW.

John Durkop d62b678473 Minor updates to address review comments
Removed unecessary checks on the ALG_SHA_224 and ALG_SHA_384 since
those are handled in config_psa.h by ensuring the correct _C is
included. Reformatted config_psa.h to be alphabetical and made the
assignments line up correctly for consistency. Fixed the guards
for ALG_SHA_224 and ALG_SHA_384 to be correct in the crypto library
source.

Gavin Acquroff 6aceb51e43 Support set *_drbg reseed interval before seed
mbedtls_ctr_drbg_set_reseed_interval() and
mbedtls_hmac_drbg_set_reseed_interval() can now be called before
their seed functions and the reseed_interval value will persist.
Previously it would be overwritten with the default value.

*_drbg_reseed_interval is now set in init() and free().

mbedtls_ctr_drbg_free() and mbedtls_hmac_drbg_free() now
reset the drbg context to the state immediately after init().

Tests:
- Added test to check that DRBG reseeds when reseed_counter
reaches reseed_interval, if reseed_interval set before seed
and reseed_interval is less than MBEDTLS_CTR_DRBG_RESEED_INTERVAL.

Gilles Peskine 14c332baee Fix a Doxygen warning
We generate the Doxygen documentation in a configuration where part of
config.h is excluded. See
https://github.com/ARMmbed/mbedtls/issues/520
```
/var/lib/build/include/mbedtls/config.h:3635: warning: documentation for unknown define MBEDTLS_PSA_HMAC_DRBG_MD_TYPE found.
```

This is a more general issue and fixing it is out of scope of my
current work. Therefore, just do something simple to silence Doxygen,
and never mind that this causes the documentation of
`MBEDTLS_PSA_HMAC_DRBG_MD_TYPE` to be omitted from the rendered
documentation. We'll fix that when we fix all the configuration macros
with a similar problem.

Ronald Cron c3623dbc76 State PSA_CRYPTO_KEY_ID_ENCODES_OWNER and USE_PSA_CRYPTO incompatibility
Code under MBEDTLS_USE_PSA_CRYPTO define is PSA client
code intended to use key identifiers of type psa_key_id_t.
Thus the MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
configuration option is incompatible with
MBEDTLS_USE_PSA_CRYPTO.

State this in config.h and check_config.h.

As a consequence:
. remove MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER from
  the full configuration, as MBEDTLS_USE_PSA_CRYPTO is
  part of it.

. add a new component in all.sh to keep testing the
  library when MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
  is set.

John Durkop 0e00519711 Add feature support for RSA for PSA crypto config
In the original attempt to add RSA support to PSA crypto config was too
generic. This set of changes adds support for the following RSA features:
PSA_WANT_ALG_RSA_PKCS1V15_CRYPT, PSA_WANT_ALG_RSA_PKCS1V15_SIGN,
PSA_WANT_ALG_RSA_OAEP, PSA_WANT_ALG_RSA_PSS, PSA_WANT_KEY_TYPE_RSA_KEY_PAIR,
and PSA_WANT_KEY_TYPE_RSA_PUBLIC_KEY.

There were also some updates to ensure the proper inclusion of PSA crypto
library code when certain features are enabled. These updates were made to
address warnings and errors in builds from the new tests for these
features being added for PSA crypto configuration.

John Durkop d032195278 Phase 2 support for MBEDTLS_PSA_CRYPTO_CONFIG
This phase adds in support for the following features being
added to the list of features that can be configured in the
include/psa/crypto_config.h header file using the PSA_WANT_ALG_xxx
macros: ECDH, HMAC, HKDF, and RSA. These changes include changes to
the PSA crypto library to use the appropriate new guards that
will allow the feature to be compiled in or out either using
new PSA_WANT_ALG_xxx or the previous MBEDTLS_xxx macros.

For HKDF and HMAC, most of the PSA library code did not have a
specific matching MBEDTLS_xxx macro for that feature, but was instead
using the generic dependent MBEDTLS_MD_C macro. The ECDH and RSA
features more closely aligned with a direct replacement with a similar
macro.

The new tests for RSA, HMAC, and HKDF would normally unset additional
dependent macros, but when attempting to implement that level of
testing it required removal of too many core features like MD_C, PK_C,
ECP_C and other low level features. This may point to additional phases of
work to complete the transition of these features to the new model.

Gilles Peskine a26b3e56cb Only include config_psa.h from config.h with new-style PSA configuration
In old-style configuration, do not include mbedtls/config_psa.h from
mbedtls/config.h.

The inclusion should not and did not break any code, but it caused our
testing to miss a break of backward compatibility (fixed in "Include
config_psa.h from psa/crypto.h"). If users have their own config.h
which enabled MBEDTLS_PSA_CRYPTO_C and worked prior to the creation of
config_psa.h and MBEDTLS_PSA_CRYPTO_CONFIG, their config.h must keep
working. By including config_psa.h from config.h in the legacy case,
we weren't testing the legacy configuration mechanism adequately.
