f87e3aea16 Update guards in PSA crypto library for ECDSA and DETERMINISTIC support
In the PSA crypto library, the code for verification of ECDSA is the same for
both MBEDTLS_PSA_BUILTIN_ALG_ECDSA and
MBEDTLS_PSA_BUILTIN_ALG_DETERMINISTIC_ECDSA. So, the guards should allow for
either one to enable the code blocks. The original implementation only had
the check for ECDSA. In order to make this work, config_psa.h was updated
to ensure when MBEDTLS_CRYPTO_CONFIG is disabled, the setting for DETERMINISTIC
is only updated if MBEDTLS_ECDSA_C is also enabled.

0ea39e0ee4 Correct use of MBEDTLS_PSA_BUILTIN_ALG_xxx in crypto library
The psa crypto library was generically using PSA_WANT_ALG_xxx, but
should have been using the correct MBEDTLS_PSA_BUILTIN_ALG_xxx
definition since that code is the builtin version. There were also
a couple of spots that needed to ensure the code block was enabled
for either ECDSA or DETERMINISTIC_ECDSA, not just one of them.

Fixed all the new ALG_ECDSA_DETERMINISTIC names to be
ALG_DETERMINISTIC_ECDSA instead.

Fixed test to use correct definitions.

714e3a1318 Minor cleanup to fix errors with some unit tests
With the new feature MBEDTLS_PSA_CRYPTO_CONFIG, needed to
add support that when the feature is disabled, if there
are defines like MBEDTLS_ECDSA_C defined, then the PSA_WANT_
equivalent define is also enabled. This ensures the guards in
the library psa_crypto will work properly.

Also fixed an error return code in the driver wrapper for cipher
encrypt setup so it will properly pass unit tests.

Ensured config.py full works properly with the new
MBEDTLS_PSA_CRYPTO_CONFIG, it should not be set when the full
option is used.

2dfaf9ca23 Update how MBEDTLS_PSA_CRYPTO_CONFIG is handled
Originally, MBEDTLS_PSA_CRYPTO_CONFIG was being used to allow
inclusion of mbedlts/config_psa.h, but that needed to be updated
so that mbedtls/config_psa.h is always included and the definitions
specific to PSA configuration are now guarded by
MBEDTLS_PSA_CRYPTO_CONFIG. This will allow for the standard setup
to continue working while new PSA configuration items to also work.

27a2688fbb Introduce public macro for maximum symmetric cipher key length
This commit introduces the public macro MBEDTLS_MAX_KEY_LENGTH,
which evaluates to an upper bound for the key lengths of all enabled
ciphers, in Bytes.

This is analogous to the already existing macros MBEDTLS_MAX_IV_LENGTH
and MBEDTLS_MAX_BLOCK_LENGTH, which provide upper bounds for the IV
and block length, respectively.

For now, MBEDTLS_MAX_KEY_LENGTH is 32 Bytes by default, and 64 in case
XTS is enabled. This is a strict overapproximation for some restricted
configurations. Ideally, the upper bound should be calculated exactly
and automatically from the list of enabled ciphers. The same applies
to the existing macros MBEDTLS_MAX_IV_LENGTH and MBEDTLS_MAX_BLOCK_LENGTH,
though, and is left for future work.

71016a9ea7 psa: Rename psa_key_file_id_t to mbedtls_svc_key_id_t
With PSA crypto v1.0.0, a volatile key identifier may
contain a owner identifier but no file is associated
to it. Thus rename the type psa_key_file_id_t to
mbedtls_svc_key_id_t to avoid a direct link with a
file when a key identifier involves an owner
identifier.

The new type name is prefixed by mbedtls to highlight
that the type is specific to Mbed TLS implementation
and not defined in the PSA Cryptography API
specification.

The svc in the type name stands for service as this
is the key identifier type from the point of view of
the service providing the Cryptography services.
The service can be completely provided by the present
library or partially in case of a multi-client service.

As a consequence rename as well:
. MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER to
  MBEDTLS_PSA_CRYPTO_KEY_ID_ENCODES_OWNER
. PSA_KEY_ID_INIT to MBEDTLS_SVC_KEY_ID_INIT
. PSA_KEY_FILE_GET_KEY_ID to MBEDTLS_SVC_KEY_ID_GET_KEY_ID

27238fcbd8 psa: Use psa_key_file_id_t as the key id type
The purpose of this commit and the following is for
psa_key_id_t to always be as defined by the PSA
Cryptography API specification.

Currently psa_key_id_t departs from its specification
definition when MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER
configuration flag is set. In that configuration, it is set
to be equal to psa_key_file_id_t which in that configuration
encodes an owner identifier along the key identifier.

Type psa_key_file_id_t was meant to be the key identifier type
used throughout the library code. If
MBEDTLS_PSA_CRYPTO_KEY_FILE_ID_ENCODES_OWNER is set it
includes both a key and owner identifier, otherwise it is
equal to psa_key_id_t.

It has not been the key identifier type throughout the
library so far because when the PSA Cryptography
specification was developped the library Doxygen
documentation was used to generate the PSA Cryptography API
specification thus the need to use psa_key_id_t and not
psa_key_file_id_t.

As this constraint does not hold anymore, move
to psa_key_file_id_t as the key identifier type throughout
the library code.

By the way, this commit updates the key identifier
initialization in the tests to be compatible with a
composit key identifier. A psa_key_id_make()
inline function is introduced to initialize key
identifiers (composit ot not) at runtime.

80b95101a9 psa: Move psa_key_file_id_t definition to crypto_types.h
`psa_key_file_id_t` was defined in `crypto_platform.h` and
not `crypto_types.h` even if it wasn't platform dependent
because back when the PSA Crypto Specification was put
together `crypto_types.h` was meant to contain only types
that were intended to make it to the specification. There
is not such constraint anymore thus move the definition
of `psa_key_file_id_t` to crypto_types.h.

6240defd17 Add MBEDTLS_TEST_CONSTANT_FLOW_MEMSAN
This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.

(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

de8593f2fe Implement and test mbedtls_ecp_write_key
mbedtls_ecp_write_key is a mirror function to mbedtls_ecp_read_key, which
writes a private key back into a byte buffer in the correct format.
This is a helpful convenience function, since the byte order is defined
differently between Montgomery and Weierstrass curves. Since this difference
is accounted for in mbedtls_ecp_read_key, it made sense to add
mbedtls_ecp_write_key for the purpose of abstracting this away such that
psa_export_key doesn't need to take byte order into account.

c52a43c2bd Implement use of internal DRBG for ecp_mul()
The case of MBEDTLS_ECP_RESTARTABLE isn't handled correctly yet: in that case
the DRBG instance should persist when resuming the operation. This will be
addressed in the next commit.

When both CTR_DRBG and HMAC_DRBG are available, CTR_DRBG is preferred since
both are suitable but CTR_DRBG tends to be faster and I needed a tie-breaker.

There are currently three possible cases to test:

- NO_INTERNAL_RNG is set -> tested in test_ecp_no_internal_rng
- it's unset and CTR_DRBG is available -> tested in the default config
- it's unset and CTR_DRBG is disabled -> tested in
  test_ecp_internal_rng_no_ctr_drbg

13996927cb Introduce configuration option for TLS 1.3 padding granularity
TLS 1.3 record protection allows the addition of an arbitrary amount
of padding.

This commit introduces a configuration option

```
   MBEDTLS_SSL_TLS13_PADDING_GRANULARITY
```

The semantics of this option is that padding is chosen in a minimal
way so that the padded plaintext has a length which is a multiple of
MBEDTLS_SSL_TLS13_PADDING_GRANULARITY.

For example, setting MBEDTLS_SSL_TLS13_PADDING_GRANULARITY to 1024
means that padded plaintexts will have length 1024, 2048, ..., while
setting it to 1 means that no padding will be used.

Continue parsing when the callback fails to parse a non critical
exception. Also document the behaviour more extensively and pass
the callback error code to the caller unaltered.

ee04e69956 Rename and clarify the default persistent location and persistence
Call persistence "default" because that is genuinely the default that
applications should use if they don't know better. It's slightly
misleading in that the default persistence when you create a key is
volatile, not this: "default" is the default persistence for
persistent keys, not the default persistence for keys in general. But
we haven't found a better name.

Introduce the term "primary local storage" to designate the default
storage location.

2f0eb51aae psa: Define mbedtls_ecc_group_to_psa() inline
On dual world platforms, we want to run the PK module (pk.c) on the NS
side so TLS can use PSA APIs via the PK interface. PK currently has a
hard dependency on mbedtls_ecc_group_to_psa() which is declared in
crypto_extra.h, but only defined in psa_crypto.c, which is only built
for the S side.

Without this change, dual world platforms get error messages like the
following.

    [Error] @0,0: L6218E: Undefined symbol mbedtls_ecc_group_to_psa (referred from BUILD/LPC55S69_NS/ARM/mbed-os/features/mbedtls/mbed-crypto/src/pk.o)

Make mbedtls_ecc_group_to_psa() inline within crypto_extra.h so that it
is available to both NS and S world code.

a9f64006ea Add support for const error description strings
Problem
-------
mbedtls_strerror is a utility function which converts an mbedTLS error code
into a human readable string. It requires the caller to allocate a buffer every
time an error code needs to be converted to a string. It is an overkill and a
waste of RAM for resource constrained microcontrollers - where the most common
use case is to use these strings for logging.

Solution
--------
The proposed commit adds two functions:

* const char * mbedtls_high_level_strerr( int error_code );
* const char * mbedtls_low_level_strerr( int error_code );

The above two functions convert the high level and low level parts of an mbedTLS
error code to human readable strings. They return a const pointer to an
unmodifiable string which is not supposed to be modified by the caller and only
to be used for logging purposes. The caller no longer needs to allocate a
buffer.

Backward Compatibility
----------------------
The proposed change is completely backward compatible as it does not change
the existing mbedtls_strerror function and ensures that it continues to behave
the same way.

Split the maximum fragment length into two - an input and output MFL
Since the server might want to have a different maximum fragment length
for the outgoing messages than the negotiated one - introduce a new way of
computing it. This commit also adds additional ssl-opt.sh tests ensuring
that the maximum fragment lengths are set as expected. 
mbedtls_ssl_get_max_frag_len() is now a deprecated function,
being an alias to mbedtls_ssl_get_output_max_frag_len(). The behaviour
of this function is the same as before.

432e7023b1 Add additional sanity checks to check_config.h
Additional sanity checks in check_config.h to ensure:
    * if test certificates are included (MBEDTLS_CERTS_C) there must be also be
      support for the core X509 feature (MBEDTLS_X509_USE_C). This has a
      secondary dependency on the public key abstraction layer (MBEDTLS_PK_C),
      necessary as the certificates will either be signed by RSA or ECDSA, and
      therefore need to be part of the library.
    * if any of the TLS protocols are defined (MBEDTLS_SSL_PROTO_xxx) then a
      key exchange method must also be defined (MBEDTLS_KEY_EXCHANGE_xxx).

Anyone who knows the library will probably not make these mistakes or will
quickly diagnose and fix them, but it is possible to compile and link both
configurations if you build only the library and not the example programs, and
therefore users may not realise immediately that there's a mistake, only
discovering it at runtime.

These checks may therefore save someone some time.

b99bd39b4e Merge mbed-crypto into mbedtls: the merge commit
Merge `unremove-non-crypto` into `mbedtls/development`. The branch
`unremove-non-crypto` was obtained by starting from `mbed-crypto/development`,
then reverting many commits that removed X.509 and TLS functionality when Mbed
Crypto forked from Mbed TLS (the “unremoval”), then make a few tweaks to
facilitate the merge.

The unremoval step restored old versions of some tls files. If a file doesn't
exist in mbed-crypto, check out the mbedtls version, regardless of what
happened during the unremoval of tls files in the crypto tree. Also
unconditionally take the mbedtls version of a few files where the
modifications are completely project-specific and are not relevant in
mbed-crypto:

* `.github/issue_template.md`: completely different. We may want to reconcile
  them independently as a follow-up.
* `.travis.yml`: would only be reverted to an earlier tls version.
* `README.md`: completely different. We may want to reconcile them
  independently as a follow-up.
* `doxygen/input/doc_mainpage.h`: the changes in crypto were minimal and not
  relevant except as a stopgap as mbed-crypto did not have its own product
  versioning in the Doxygen documentation.
* `tests/.jenkins/Jenkinsfile`: completely different.
* `tests/data_files/Makefile`: there were no changes in mbed-crypto,
  but the unremoval step restored an old version.

Shell script for everything to do after the merge apart from the conflict
resolution:

Resolve the remaining conflicts:

* `library/CMakeLists.txt`:
    * Keep the TLS definition of `src_crypto`
    * `USE_SHARED_MBEDTLS_LIBRARY`: keep all three libraries, with both
      `include` and `crypto/include` in `target_include_directories`, all with
      version `2.21.0`.
* `programs/Makefile`:
    * Reconcile the APPS lists (add/add from a differently-formatted common
      ancestor): insert the `psa/*` from crypto into the tls list.
    * Keep the `fuzz` target defined only in tls version.
    * Keep the recipe (only in tls version) cleaning `ssl_pthread_server`
      stuff for the `clean` target.
* `scripts/config.py`:
    * `include_in_full`: add/add conflict. Keep both.
* `tests/scripts/all.sh`:
    * `component_test_no_use_psa_crypto_full_cmake_asan`: partially old
      version in crypto. Take the tls version.
    * `component_test_malloc_0_null` and more: take
      `component_test_malloc_0_null` from crypto (with `config.py` rather than
      `config.pl`, and with `$ASAN_FLAGS` rather than an explicit list), but
      add the call to `ssl-opt.sh` from tls. Take the other components from
      crypto.

With this commit, building and running the unit tests with both `make ` and
`cmake` work in the default configuration on Linux. Other platforms, build
systems and configurations are likely not to work, and there is some
regression in test coverage.

There is some loss of functionality because the unremoval step restored older
versions of tls content. This commit contains the latest tls version of
tls-only files, but some changes from the tls side in files that existed on
both sides have regressed. Most problematic changes are hunks that remove some
tls-specific feature and contain either a C preprocessor symbol identifying a
tls-specific module or option, or the name of a tls-specific file. Hunks
that remove a tls-specific preprocessor symbol can be identified with the
regular expression `^-.*MBEDTLS_(ERR_)?(PKCS11|X509|NET|SSL)_`.

Subsequent commits will revert a few parts of the patch from this merge commit
in order to restore the tls functionality that it removes, ensure that the
test coverage includes what was covered in either branch, and fix test
failures.

43aa905d1e DHM functions are not part of x509
In the old days, key parsing was part of x509, but these days it's
part of crypto.
