ded2a42ac1 Use a union instead of casts
Same intended semantics, no casts.

Limitation: this doesn't work on architectures where
sizeof(uintptr_t) < sizeof(void*), which is somewhat weird but possible if
pointers contain redundant information.

49d7ddf7f3 Serializing a context does not save the user data
The user data is typically a pointer to a data structure or a handle which
may no longer be valid after the session is restored. If the user data needs
to be preserved, let the application do it. This way, it is a conscious
decision for the application to save/restore either the pointer/handle
itself or the object it refers to.

69477b5706 Add a field for application data to TLS structures
In structure types that are passed to user callbacks, add a field that the
library won't ever care about. The application can use this field to either
identify an instance of the structure with a handle, or store a pointer to
extra data.

f3ebd90a1c SECLIB-667: Accelerate SHA-256 with A64 crypto extensions
Provide an additional pair of #defines, MBEDTLS_SHA256_USE_A64_CRYPTO_IF_PRESENT
and MBEDTLS_SHA256_USE_A64_CRYPTO_ONLY. At most one of them may be
specified. If used, it is necessary to compile with -march=armv8-a+crypto.

The MBEDTLS_SHA256_PROCESS_ALT and MBEDTLS_SHA256_ALT mechanisms
continue to work, and are mutually exclusive with A64_CRYPTO.

There should be minimal code size impact if no A64_CRYPTO option is set.

58d2383ef4 Remove mbedtls_psa_tls_psa_ec_to_ecpoint()
Initially this function was doing something because the output format of
psa_export_public() didn't match the ECPoint format that TLS wants.

Then it became a no-op then the output format of psa_export_public()
changed, but it made sense to still keep the function in case the format
changed again. Now that the PSA Crypto API has reached 1.0 status, this
is unlikely to happen, so the no-op function is no longer useful.

Removing it de-clutters the code a bit; while at it we can remove a
temporary stack buffer (that was up to 133 bytes).

It's OK to remove this function even if it was declared in a public
header, as there's a warning at the top of the file saying it's not part
of the public API.

59753768f0 Simplify the definition of a macro
Relying on a PSA_VENDOR macro is not ideal, since the standard doesn't
guarantee this macro exists, but OTOH relying on
MBEDTLS_ECP_DP_xxx_ENABLED was even less ideal, so I believe this is
still an improvement.

533a728392 mbedtls_ssl_config: Replace bit-fields by separate bytes
This slightly increases the RAM consumption per context, but saves code
size on architectures with an instruction for direct byte access (which is
most of them).

Although this is technically an API break, in practice, a realistic
application won't break: it would have had to bypass API functions and rely
on the field size (e.g. relying on -1 == 1 in a 1-bit field).

e3d9c9d99b PSA operation structures: move less-used fields to the end
Move fields around to have fewer accesses outside the 128-element Thumb
direct access window.

In psa_hkdf_key_derivation_t, move the large fields (output_block, prk,
hmac) after the state bit-fields. Experimentally, it's slightly better
to put hmac last.

Other operations structures don't go outside the window, at least when not
considering nested structures.

Results (arm-none-eabi-gcc 7.3.1, build_arm_none_eabi_gcc_m0plus build):

09c02ee95f Make PSA headers more self-contained
Several files among include/psa/crypto_*.h are not meant to be included
directly, and are not guaranteed to be valid if included directly. This
makes it harder to perform some static analyses. So make these files more
self-contained so that at least, if included on their own, there is no
missing macro or type definition (excluding the deliberate use of forward
declarations of structs and unions).

853c0da8de Fix for pkcs12 with NULL or zero length password
Previously passing a NULL or zero length password into either

loop, and it was also possible to pass a NULL password, with a non-zero
length, which would cause memory corruption.
I have fixed these errors, and improved the documentation to reflect the

f7b4137e69 Untangle PSA_ALG_IS_HASH_AND_SIGN and PSA_ALG_IS_SIGN_HASH
The current definition of PSA_ALG_IS_HASH_AND_SIGN includes
PSA_ALG_RSA_PKCS1V15_SIGN_RAW and PSA_ALG_ECDSA_ANY, which don't strictly
follow the hash-and-sign paradigm: the algorithm does not encode a hash
algorithm that is applied prior to the signature step. The definition in
fact encompasses what can be used with psa_sign_hash/psa_verify_hash, so
it's the correct definition for PSA_ALG_IS_SIGN_HASH. Therefore this commit
moves definition of PSA_ALG_IS_HASH_AND_SIGN to PSA_ALG_IS_SIGN_HASH, and
replace the definition of PSA_ALG_IS_HASH_AND_SIGN by a correct one (based
on PSA_ALG_IS_SIGN_HASH, excluding the algorithms where the pre-signature
step isn't to apply the hash encoded in the algorithm).

In the definition of PSA_ALG_SIGN_GET_HASH, keep the condition for a nonzero
output to be PSA_ALG_IS_HASH_AND_SIGN.

Everywhere else in the code base (definition of PSA_ALG_IS_SIGN_MESSAGE, and
every use of PSA_ALG_IS_HASH_AND_SIGN outside of crypto_values.h), we meant
PSA_ALG_IS_SIGN_HASH where we wrote PSA_ALG_IS_HASH_AND_SIGN, so do a
global replacement.
```
git grep -l IS_HASH_AND_SIGN ':!include/psa/crypto_values.h' | xargs perl -i -pe 's/ALG_IS_HASH_AND_SIGN/ALG_IS_SIGN_HASH/g'

e0edc8407b Add mbedtls_ssl_conf_groups to API
mbedtls_ssl_conf_groups allows supported groups for key
sharing to be configured via their IANA NamedGroup ID.

This is added in anticipation of PQC and Hybrid key
sharing algorithms being integrated into Mbed TLS.

mbedtls_ssl_conf_curves is deprecated in favor of
mbedtls_ssl_conf_groups. handshake_init has been
modified to translate and copy curves configured
via conf_curves into a heap allocatied array of
NamedGroup IDs. This allows the refactoring of code
interacting with conf_curve related variables (such
as curve_list) to use NamedGroup IDs while retaining
the deprecated API.

acd2d0e923 New algorithm PSA_ALG_RSA_PSS_ANY_SALT
This is a variant of PSA_ALG_RSA_PSS which currently has exactly the same
behavior, but is intended to have a different behavior when verifying
signatures.

In a subsequent commit, PSA_ALG_RSA_PSS will change to requiring the salt
length to be what it would produce when signing, as is currently documented,
whereas PSA_ALG_RSA_PSS_ANY_SALT will retain the current behavior of
allowing any salt length (including 0).

Changes in this commit:

* New algorithm constructor PSA_ALG_RSA_PSS_ANY_SALT.
* New predicates PSA_ALG_IS_RSA_PSS_STANDARD_SALT (corresponding to
  PSA_ALG_RSA_PSS) and PSA_ALG_IS_RSA_PSS_ANY_SALT (corresponding to
  PSA_ALG_RSA_PSS_ANY_SALT).
* Support for the new predicates in macro_collector.py (needed for
  generate_psa_constant_names).

MBEDTLS_CHECK_RETURN_TYPICAL defaults off, but is enabled if
MBEDTLS_CHECK_RETURN_WARNING is enabled at compile time.
(MBEDTLS_CHECK_RETURN_CRITICAL is always enabled.)

The default is off so that a plausible program that builds with one version

913fc5fff3 Better default for MBEDTLS_CHECK_RETURN in config.h
An empty expansion is possible, but as documented its effect is to disable
the feature, so that isn't a good example. Instead, use the GCC
implementation as the default: it's plausible that it could work even on
compilers that don't advertise themselves as sufficiently GCC-like to define
__GNUC__, and if not it gives users a concrete idea of what the macro is
supposed to do.

e41803af9c Change DES and AES functions to MBEDTLS_CHECK_RETURN_TYPICAL
For all of these functions, the only possible failures are a hardware
accelerator (not possible unless using an ALT implementation), an internal

Exception: the self-tests, which serve little purpose if their status isn't

463adf4536 Define indirection macros MBEDTLS_CHECK_RETURN_xxx
Define macros MBEDTLS_CHECK_RETURN_CRITICAL, MBEDTLS_CHECK_RETURN_TYPICAL
and MBEDTLS_CHECK_RETURN_OPTIONAL so that we can indicate on a
function-by-function basis whether checking the function's return value is
almost always necessary (CRITICAL), typically necessary in portable
applications but unnecessary in some reasonable cases (TYPICAL), or
typically unnecessary (OPTIONAL).

Update the documentation of MBEDTLS_CHECK_RETURN accordingly. This is split
between the user documentation (Doxygen, in config.h) and the internal
documentation (non-Doxygen, in platform_util.h, of minor importance since
the macro isn't meant to be used directly).

7820a574f1 Catch failures of AES or DES operations
Declare all AES and DES functions that return int as needing to have
their result checked, and do check the result in our code.

A DES or AES block operation can fail in alternative implementations of
mbedtls_internal_aes_encrypt() (under MBEDTLS_AES_ENCRYPT_ALT),
mbedtls_internal_aes_decrypt() (under MBEDTLS_AES_DECRYPT_ALT),
mbedtls_des_crypt_ecb() (under MBEDTLS_DES_CRYPT_ECB_ALT),
mbedtls_des3_crypt_ecb() (under MBEDTLS_DES3_CRYPT_ECB_ALT).
A failure can happen if the accelerator peripheral is in a bad state.
Several block modes were not catching the error.

This commit does the following code changes, grouped together to avoid
having an intermediate commit where the build fails:

* Add MBEDTLS_CHECK_RETURN to all functions returning int in aes.h and des.h.
* Fix all places where this causes a GCC warning, indicating that our code
  was not properly checking the result of an AES operation:
    * In library code: on failure, goto exit and return ret.
    * In pkey programs: goto exit.
    * In the benchmark program: exit (not ideal since there's no error
      message, but it's what the code currently does for failures).
    * In test code: TEST_ASSERT.
* Changelog entry.

Add functions to read the type, mode, name and key_bitlen fields from

likely to care about.

TLS code also uses iv_size and block_size, which it might make sense to
expose, but most applications shouldn't need those, so I'm not exposing them
for now.

fadbdbb576 Store TLS version in SSL session structure
Instances of `mbedtls_ssl_session` represent data enabling session resumption.

With the introduction of TLS 1.3, the format of this data changes. We therefore
need TLS-version field as part of `mbedtlsl_ssl_session` which allows distinguish
1.2 and 1.3 sessions.

This commit introduces such a TLS-version field to mbedtls_ssl_session.

The change has a few ramifications:

- Session serialization/deserialization routines need to be adjusted.

  This is achieved by adding the TLS-version after the header of
  Mbed TLS version+config, and by having the subsequent structure
  of the serialized data depend on the value of this field.

  The details are described in terms of the RFC 8446 presentation language.

  The 1.2 session (de)serialization are moved into static helper functions,
  while the top-level session (de)serialization only parses the Mbed TLS
  version+config header and the TLS-version field, and dispatches according
  to the found version.

  This way, it will be easy to add support for TLS 1.3 sessions in the future.

- Tests for session serialization need to be adjusted

- Once we add support for TLS 1.3, with runtime negotiation of 1.2 vs. 1.3,
  we will need to have some logic comparing the TLS version of the proposed session
  to the negotiated TLS version. For now, however, we only support TLS 1.2,
  and no such logic is needed. Instead, we just store the TLS version in the
  session structure at the same point when we populate mbedtls_ssl_context.minor_ver.

The change introduces some overlap between `mbedtls_ssl_session.minor_ver` and
`mbedtls_ssl_context.minor_ver`, which should be studied and potentially resolved.
However, with both fields being private and explicitly marked so, this can happen
in a later change.

b795332401 mbedtls_rsa_rsassa_pss_*: improve documentation
Hashes used in RSA-PSS encoding (EMSA-PSS-ENCODE, see §9.1.1 in RFC
8017):

- H1: Hashing the message (step 2)
- H2: Hashing in the salt (step 6)
- H3: Mask generation function (step 9)

According to the standard:

- H1 and H2 MUST be done by the same hash function
- H3 is RECOMMENDED to be the same as the hash used for H1 and H2.

According to the implementation:

- H1 happens outside of the function call. It might or might not happen
and the implementation might or might not be aware of the hash used.
- H2 happens inside the function call, consistency with H1 is not
enforced and might not even be possible to detect.
- H3 is done with the same hash as H2 (with the exception of
mbedtls_rsassa_pss_verify_ext(), which takes a dedicated parameter for
the hash used in the MGF).

Issues with the documentation:

- The comments weren't always clear about the three hashes involved and
often only mentioned two of them (which two varied from function to
function).
- The documentation was giving the impression that the standard
recommends aligning H2 and H1 (which is not a recommendation but a
must).

d8f32e72b4 Move export callback and context to the end of SSL context
This saves some code when compiling for Thumb, where access to
fields with offset index > 127 requires intermediate address
computations. Frequently used fields should therefore be located
at the top of the structure, while less frequently used ones --
such as the export callback -- can be moved to the back.

39957503c5 Remove secp256k1 from the default X.509 and TLS profiles
For TLS, secp256k1 is deprecated by RFC 8422 §5.1.1. For X.509,
secp256k1 is not deprecated, but it isn't used in practice, especially
in the context of TLS where there isn't much point in having an X.509
certificate which most peers do not support. So remove it from the
default profile. We can add it back later if there is demand.

b1940a76ad In TLS, order curves by resource usage, not size
TLS used to prefer larger curves, under the idea that a larger curve has a
higher security strength and is therefore harder to attack. However, brute
force attacks are not a practical concern, so this was not particularly
meaningful. If a curve is considered secure enough to be allowed, then we
might as well use it.

So order curves by resource usage. The exact definition of what this means
is purposefully left open. It may include criteria such as performance and
memory usage. Risk of side channels could be a factor as well, although it
didn't affect the current choice.

The current list happens to exactly correspond to the numbers reported by
one run of the benchmark program for "full handshake/s" on my machine.

5752e599b3 Reduce the default ECP window size
MBEDTLS_ECP_WINDOW_SIZE is a compromise between memory usage (growing based
on the value) and performance (faster with larger values). There are
disminishing returns as the value grows larger. Based on Manuel's benchmarks
recorded in https://github.com/ARMmbed/mbedtls/issues/4127, 4 is a good
compromise point, with larger values bringing little advantage. So reduce
the default from 6 to 4.

Document the default value as in optimized for performance mostly, but don't
document the specific value, so we may change it later or make it
platform-dependent.
