Manuel Pégourié-Gonnard 8857984b2f Replace hash_info macro with MD macro
Now the MD macro also accounts for PSA-only hashes.

Just a search-and-replace, plus manually removing the definition in
hash_info.h.

Valerio Setti 77a75685ed pk: align library and tests code to the new internal functions
Note = programs are not aligned to this change because:
- the original mbedtls_pk_ec is not ufficially deprecated

  the legacy version of that function is available in that

Manuel Pégourié-Gonnard b8b07aa24a Handle errors from functions that now return int
A few functions were changed from returning void to returning int three
commits ago. Make sure their callers check the return values.

This commits was basically a matter of declaring newly-int-returning
functions MBEDTLS_CHECK_RETURN_CRITICAL and then fixing the resulting
warnings. A few functions had to be made int in the process; they were
applied the same process as well.

Therefore read/write functions used in the initial key exchange are

Fix bug whereby the supported signature algorithm list sent by the

length to be written, and thus the first element would get overwritten,

Gilles Peskine 945b23c46f Include platform.h unconditionally: automatic part
We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.

There should be no change in behavior since just including the header should
not change the behavior of a program.

This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:

```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

Leonid Rozenboim 287527042b Avoid potentially passing NULL arguments
Several call sites flagged by Coverity that may potentially cause
a pointer argument to be NULL.

In two cases the issue is using a function call as a parameter to
a second function, where the first function may return NULL, while
the second function does not check for the NULL argument value.

Remaining case is when static configuration is mixed with run-time
decision, that could result in a data buffer argument being NULL.

Glenn Strauss 8315811ea7 Remove restrictive proto ver negotiation checks
Overly restrictive protocol version negotiation checks might be
"version intolerant".  TLS 1.3 and DTLS 1.3 move the version to
the "supported_versions" ClientHello extension.

Glenn Strauss 60bfe60d0f mbedtls_ssl_ciphersuite_t min_tls_version,max_tls_version
Store the TLS version in tls_version instead of major, minor version num

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is not compatible, as the struct is now smaller.

Reduce size of mbedtls_ssl_ciphersuite_t

members are defined using integral types instead of enums in
order to pack structure and reduce memory usage by internal
ciphersuite_definitions[]

Glenn Strauss da7851c825 Rename mbedtls_ssl_session minor_ver to tls_version
Store the TLS version instead of minor version number in tls_version.

Note: struct member size changed from unsigned char to uint16_t
Due to standard structure padding, the structure size does not change
unless alignment is 1-byte (instead of 2-byte or more)

Note: existing application use which accesses the struct member
(using MBEDTLS_PRIVATE) is compatible on little-endian platforms,
but not compatible on big-endian platforms.  The enum values for
the lower byte of MBEDTLS_SSL_VERSION_TLS1_2 and of
MBEDTLS_SSL_VERSION_TLS1_3 matches MBEDTLS_SSL_MINOR_VERSION_3 and
MBEDTLS_SSL_MINOR_VERSION_4, respectively.

Note: care has been taken to preserve serialized session format,
which uses only the lower byte of the TLS version.
