a8ade16ffd Gate secure element support by a separate config option
Secure element support has its own source file, and in addition
requires many hooks in other files. This is a nontrivial amount of
code, so make it optional (but default on).

adbec81cc4 Remove the deprecated PSA_ALG_SELECT_RAW option
This change affects the psa_key_derivation_s structure. With the buffer
removed from the union, it is empty if MBEDTLS_MD_C is not defined.

We can avoid undefined behaviour by adding a new dummy field that is
always present or make the whole union conditional on MBEDTLS_MD_C.

In this latter case the initialiser macro has to depend on MBEDTLS_MD_C
as well. Furthermore the first structure would be either
psa_hkdf_key_derivation_t or psa_tls12_prf_key_derivation_t both of
which are very deep and would make the initialisation macro difficult
to maintain, therefore we go with the first option.

16de4a4017 Adapt the derive_setup tests to the new API
Part of the tests are adapted in this commit, another part is already
covered by the derive_input tests and some of them are not applicable to
the new API (the new API does not request capacity at the setup stage).

The test coverage temporarily drops with this commit, the two test cases
conserning capacity will be re-added in a later commit.

99dd6acdce Add test cases for derive_input
In the 1.0 API some functionality has been split from the
psa_key_derivation_setup() function and is now done with the
psa_key_derivation_input_*() functions. The new tests maintain the
existing test coverage of this functionality.

71a4c9125b Add flag for removing deprecated API
Add the compile time option PSA_PRE_1_0_KEY_DERIVATION. If this is not
turned on, then the function `psa_key_derivation()` is removed.

Most of the tests regarding key derivation haven't been adapted to the
new API yet and some of them have only been adapted partially. When this
new option is turned off, the tests using the old API and test cases
using the old API of partially adapted tests are skipped.

The sole purpose of this option is to make the transition to the new API
smoother. Once the transition is complete it can and should be removed
along with the old API and its implementation.

72662a495c Refactor receive_uint32()
Call `greentea_getc()` 8 times, and then `unhexify` once, instead of
calling `receive_byte()`, which inside calls `greentea_getc()` twice,

5075f4df18 Update the test encoding to support python3
Since Python3 handles encoding differently than Python2,
a change in the way the data is encoded and sent to the target is needed.
1. Change the test data to be sent as hex string
2. Convert the characters to binary bytes.

This is done because the mbed tools translate the encoding differently
(mbed-greentea, and mbed-htrunner)

1838e82190 Rename psa_helpers.function to psa_crypto_helpers.h
This file isn't like the other .function files: it isn't concatenated
by a separate preprocessing script, but included via C preprocessing.

Rename this file to .h. This isn't a normal C header, because it
defines auxiliary functions. But the functions aren't big and we only
have one compilation unit per executable, so this is good enough for
what we're doing.

<assert.h> is not included, but it's fragile, because it means the

5ab80efa10 test: Check empty buffer decryption for chachapoly
Previously, even in the Chacha20 and Chacha20-Poly1305 tests, we would
test that decryption of an empty buffer would work with
MBEDTLS_CIPHER_AES_128_CBC.

Make the cipher used with the dec_empty_buf() test configurable, so that
Chacha20 and Chacha20-Poly1305 empty buffer tests can use ciphers other
than AES CBC. Then, make the Chacha20 and Chacha20-Poly1305 empty buffer
tests use the MBEDTLS_CIPHER_CHACHA20 and
MBEDTLS_CIPHER_CHACHA20_POLY1305 cipher suites.

1153e7bd57 Replace all calls to mbedtls_psa_crypto_free by PSA_DONE
Replace all calls to mbedtls_psa_crypto_free in tests by PSA_DONE.
This is correct for most tests, because most tests close open keys. A
few tests now fail; these tests need to be reviewed and switched back
to mbedtls_psa_crypto_free if they genuinely expected to end with some
slots still in use.

952f40962a Create PSA-specific helper function file
Create a specific file for helper functions that are related to the
PSA API. The reason for a separate file is so that it can include
<psa/crypto.h>, without forcing this header inclusion into every test
suite. In this commit, psa_helpers.function doesn't need psa/crypto.h
yet, but this will be the case in a subsequent commit.

Move PSA_ASSERT to psa_helpers.function, since that's the sort of
things it's for.

Include "psa_helpers.function" from the PSA crypto tests.

In the ITS test, don't include "psa_helpers". The ITS tests are
meant to stand alone from the rest of the library.

2de07f1dd1 ssl: Don't access non-existent encrypt_then_mac field

MBEDTLS_SSL_SOME_MODES_USE_MAC, mbedtls_ssl_derive_keys() and
